The following code creates and initialises a simple progress bar using CFUserNotification API. How would I add a callback to update the progress bar ? With this code, the progress is at the constant value indicated by prog.
float prog = 0.1;
CFNumberRef cfNum = CFNumberCreate(kCFAllocatorDefault,kCFNumberFloatType, &prog);
const void* keys[] = { kCFUserNotificationAlertHeaderKey, kCFUserNotificationProgressIndicatorValueKey };
const void* vals[] = { CFSTR("Progress Bar"), cfNum};
CFDictionaryRef dict = CFDictionaryCreate(0, keys, vals,
sizeof(keys)/sizeof(*keys),
&kCFTypeDictionaryKeyCallBacks,
&kCFTypeDictionaryValueCallBacks);
CFUserNotificationRef pDlg = NULL;
pDlg = CFUserNotificationCreate(kCFAllocatorDefault, 0,
kCFUserNotificationPlainAlertLevel,
&nRes, dict);

I have a method in viewmodel that I want to execute infinity till client stop that.
This loop should work for each button separately and stop that too.
But when I execute the loop for fourth time, application hangs.
How can I manage the loop and run it for four separate objects
This is my method in viewmodel:
fun getLocationInfinity(context: Context, tripId: Long, passengerId: Int) =
viewModelScope.launch {
val gpsTracker = LocationGpsTracker(context, 0, 0)
val netGpsTracker = LocationGpsTrackerNetwork(context)
var way = Way()
way.latitude1 = gpsTracker.getLatitude()
way.longitude1 = gpsTracker.getLongitude()
way.accuracy1 = gpsTracker.getAccuracy()
way.latitudeNet1 = netGpsTracker.getLatitude()
way.longitudeNet1 = netGpsTracker.getLongitude()
way.accuracyNet1 = netGpsTracker.getAccuracy()
while (isActive) {
if (_passengerSwitch.value?.get(passengerId - 1) == true) {
way.latitude2 = way.latitude1
way.longitude2 = way.longitude1
way.accuracy2 = way.accuracy1
way.latitudeNet2 = way.latitudeNet1
way.longitudeNet2 = way.longitudeNet1
way.accuracyNet2 = way.accuracyNet1
way.latitude1 = gpsTracker.getLatitude()
way.longitude1 = gpsTracker.getLongitude()
way.accuracy1 = gpsTracker.getAccuracy()
way.latitudeNet1 = netGpsTracker.getLatitude()
way.longitudeNet1 = netGpsTracker.getLongitude()
way.accuracyNet1 = netGpsTracker.getAccuracy()
_way.postValue(way)
val tripDetails = TripDetails(
latitude1 = way.latitude1,
latitude2 = way.latitude2,
longitude1 = way.longitude1,
longitude2 = way.longitude2,
accuracy1 = way.accuracy1,
accuracy2 = way.accuracy2,
latitudeNet1 = way.latitudeNet1,
latitudeNet2 = way.latitudeNet2,
longitudeNet1 = way.longitudeNet1,
longitudeNet2 = way.longitudeNet2,
accuracy1Net = way.accuracyNet1,
accuracy2Net = way.accuracyNet2,
distance = null,
isCalculated = false,
tripId = tripId.toInt(),
isEnded = false
)
localRepository.insertLocation(tripDetails)
delay(2000)
}
}
}
The delay() call needs to be outside your if-block. Otherwise, if the condition is false, this loop will never suspend so it never relinquishes the thread.
I'm looking to make a script that cycles through a dropdown list and creates a pdf for each.
https://docs.google.com/spreadsheets/d/1HrXWkNXT7aEWOXkngiuSX9Sr1F0V4Y_rZH6Eg3mjaJQ/edit?usp=sharing
First I would like to check if B2 is not empty, then if so create pdf and change A2 to the next option until all are complete. I have a basic script but feel free to disregard!
function loopScript() {
const ss = SpreadsheetApp.getActiveSpreadsheet();
const interface = ss.getSheetByName("Interface");
var folderID = "###GOOGLE DRIVE FOLDER ID###";
var folder = DriveApp.getFolderById(folderID);
const exportOptions = 'exportFormat=pdf&format=pdf'
+ '&size=A4'
+ '&portrait=true'
+ '&scale=4'
+ '&fith=true&source=labnol'
+ '&top_margin=0.05'
+ '&bottom_margin=0.05'
+ '&left_margin=1.00'
+ '&right_margin=0.25'
+ '&sheetnames=false&printtitle=false'
+ '&pagenumbers=false&gridlines=false'
+ '&fzr=false'
+ '&gid=125740569';
var params = {method:"GET",headers:{"authorization":"Bearer "+ ScriptApp.getOAuthToken()}};
var response = UrlFetchApp.fetch(url+exportOptions, params).getBlob();
const nameFile = "NAME OF FILE" + ".pdf" ;
folder.createFile(response.setName(nameFile));
DriveApp.createFile(response.setName(nameFile));
}
I believe your goal is as follows.
You want to check the cell "B2". When the cell "B2" is not empty, you want to set the value of the dropdown list of cell "A2" to the next value of the list.
For example, when the dropdown list is Joe, Barry, Jane, Fred and the cell "A2" is Barry, you want to set the cell to Jane.
In this case, how about the following modified script?
Modified script:
From:
const ss = SpreadsheetApp.getActiveSpreadsheet();
const interface = ss.getSheetByName("Interface");
To:
const ss = SpreadsheetApp.getActiveSpreadsheet();
const interface = ss.getSheetByName("Interface");
if (interface.getRange("B2").isBlank()) return;
const range = interface.getRange("A2");
const values = [...new Set(range.getDataValidation().getCriteriaValues()[0].getValues().flat())];
const nextValue = values[values.indexOf(range.getValue()) + 1] || values[0];
range.setValue(nextValue);
In this modified script, when the cell "B2" is empty, the script is finished. When the cell "B2" is not empty, the script is run and the cell "A2" is updated and your script for creating the PDF file is run.
Note:
In above modified script, when the dropdown list is Joe, Barry, Jane, Fred and the cell "A2" is Fred, the value of Joe is set. If you want to change this, please modify the above script.
In your current script, url is not defined. Please be careful this.
References:
isBlank()
getDataValidation()
getCriteriaValues()
Issue:
If I understand you correctly, you want to do the following:
For each dropdown in A2, check if the formula in B2 populates any values (based on data from sheet Data).
If any value is populated in B due to the formula, create a PDF file using the value of A2 for the file name (you have achieved this already).
Method 1:
In this case, I'd suggest the following workflow:
Retrieve an array with the accepted values from A2 dropdown (you can use the method used in Tanaike's answer).
Iterate through these values, and for each one, set the A2 value, using Range.setValue.
Call flush in order to update the data in B2 according to the current value in A2.
Check if B2 is blank (using Range.isBlank, for example).
If B2 is not blank, create the drive file.
function loopScript() {
const ss = SpreadsheetApp.getActiveSpreadsheet();
const interface = ss.getSheetByName("Interface");
const range = interface.getRange("A2");
const values = [...new Set(range.getDataValidation().getCriteriaValues()[0].getValues().flat())].filter(String);
values.forEach(name => {
range.setValue(name);
SpreadsheetApp.flush();
if (!interface.getRange("B2").isBlank()) {
// CODE FOR CREATING FILE
}
});
}
Method 2:
In the previous method, setValue, flush, getRange and isBlank are used iteratively, greatly increasing the amount of calls to the spreadsheet. This is not the best practice, as it will slow down the script (see Minimize calls to other services), and this will get worse if there are more valid options for the dropdown.
Therefore, since the data this formula is using can be found in sheet Data, I'd suggest using that source data instead of the formula, in order to minimize the calls to the spreadsheet.
In this case, you could follow this workflow:
Get all data in Data at once using Range.getValues.
Get all valid options in the data validation from A2, as in method 1.
For each option, check if there's any row in Data that has this option in column A and a non-empty cell in B.
If there is some data for that option, create the file.
function loopScript() {
const ss = SpreadsheetApp.getActiveSpreadsheet();
const interface = ss.getSheetByName("Interface");
const data = ss.getSheetByName("Data");
const DATA_FIRST_ROW = 2;
const dataValues = data.getRange(DATA_FIRST_ROW,1,data.getLastRow()-DATA_FIRST_ROW+1,2).getValues();
const range = interface.getRange("A2");
const values = [...new Set(range.getDataValidation().getCriteriaValues()[0].getValues().flat())].filter(String);
values.forEach(name => {
const optionValues = dataValues.filter(dataRow => dataRow[0] === name);
const nonEmpty = optionValues.some(optionValue => optionValue[1] !== "");
if (nonEmpty) {
// CODE FOR CREATING FILE
}
});
}
Thanks to everyone's help, I ended up using Tanaike's advice and continued on to come up with this:
function sendAll() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var interface = ss.getSheetByName("Interface");
var range = interface.getRange("A2");
// Cell of validation
const values = [...new Set(range.getDataValidation().getCriteriaValues()
[0].getValues().flat())]; // Gets array of validation
var first = values[0];
// 1st cell of validation
var number = values.length - 1;
// Length of validation
range.setValue(first);
// Sets value to first one
for(i = 0;i < number;i++) {
// Loop number of names
if (interface.getRange("B2").getValue().length > 0) {
// Sheet isn't empty
var person = interface.getRange("A2").getValue();
const url = 'MY SHEET URL';
var folderID = "MY FOLDER ID";
var folder = DriveApp.getFolderById(folderID);
const exportOptions = 'exportFormat=pdf&format=pdf'
+ '&size=A4'
+ '&portrait=true'
+ '&scale=4'
+ '&fith=true&source=labnol'
+ '&top_margin=0.05'
+ '&bottom_margin=0.05'
+ '&left_margin=1.00'
+ '&right_margin=0.25'
+ '&sheetnames=false&printtitle=false'
+ '&pagenumbers=false&gridlines=false'
+ '&fzr=false'
+ '&gid=0';
var params = {method:"GET",headers:{"authorization":"Bearer "+
ScriptApp.getOAuthToken()}};
var response = UrlFetchApp.fetch(url+exportOptions, params).getBlob();
const nameFile = person + ".pdf" ;
folder.createFile(response.setName(nameFile));
DriveApp.createFile(response.setName(nameFile));
const nextValue = values[values.indexOf(range.getValue()) + 1] || values[0];
range.setValue(nextValue);
}
else {const nextValue = values[values.indexOf(range.getValue()) + 1] ||
values[0];
range.setValue(nextValue);}
}
}
I am using model.GetType().GetProperties() with foreach to compare properties of 2 object of same class.
like this
foreach (var item in kayit.GetType().GetProperties())
{
var g = item.GetValue(plu);
var b = item.GetValue(kayit);
if (g is string && b is string&& g!=b)
{
a += item.Name + "*";
}
else if (g is DateTime&& b is DateTime&& g!=b)
{
a += item.Name + "*";
}
}
But the problem is even if they have the same value g!=b returns a true all the time. I have used a break point to prove this and they are literally same thing. Actually I am taking the value putting it in textbox then creating another class after button click and comaring to see the changed properties. So even if I don't change anything it doesn't read the mas equals. Can someone help me about this please?
more info:
I get the plu from database and populate my control with it:
txtorder.Text = plu.OrderNo;
dtporder.Value = nulldate(plu.OrderDate);
dtp1fit.Value = nulldate(plu.FirstFitDate);
dtp1yorum.Value = nulldate(plu.FirstCritDate);
dtp2fit.Value = nulldate(plu.SecondFitDate);
dtp2yorum.Value = nulldate(plu.SecondCritDate);
dtpsizeset.Value = nulldate(plu.SizeSetDate);
dtpsizesetok.Value = nulldate(plu.SizeSetOkDate);
dtpkumasplan.Value = nulldate(plu.FabricOrderByPlan);
txtTedarikci.Text = plu.Fabric_Supplier;
dtpkumasFP.Value = nulldate(plu.FabricOrderByFD);
dtpfabarrive.Value = nulldate(plu.FabricArrive);
dtpbulk.Value = nulldate(plu.BulkFabricDate);
dtpbulkok.Value = nulldate(plu.BulkConfirmDate);
dtpaccessory.Value = nulldate(plu.AccessoriesDate);
dtpaccessoryarrive.Value = nulldate(plu.AccessoriesArriveDate);
dtpcutok.Value = nulldate(plu.ProductionStartConfirmation);
dtpcutstart.Value = nulldate(plu.ProductionStart);
dtpshipmentdate.Value = nulldate(plu.ShipmentDate);
dtpshipmentsample.Value = nulldate(plu.ShipmentSampleDate);
dtpshippedon.Value = nulldate(plu.Shippedon);
nulldate is just a method where I change null values to my default value.
And this is what I do after button click:
var kayit = new uretim();
kayit.OrderNo = txtorder.Text.ToUpper();
kayit.OrderDate = vdat(dtporder.Value);
kayit.FirstFitDate = vdat(dtp1fit.Value);
kayit.FirstCritDate = vdat(dtp1yorum.Value);
kayit.SecondFitDate = vdat(dtp2fit.Value);
kayit.SecondCritDate = vdat(dtp2yorum.Value);
kayit.SizeSetDate = vdat(dtpsizeset.Value);
kayit.SizeSetOkDate = vdat(dtpsizesetok.Value);
kayit.FabricOrderByPlan = vdat(dtpkumasplan.Value);
kayit.Fabric_Supplier = txtTedarikci.Text;
kayit.FabricOrderByFD = vdat(dtpkumasFP.Value);
kayit.FabricArrive = vdat(dtpfabarrive.Value);
kayit.BulkFabricDate = vdat(dtpbulk.Value);
kayit.BulkConfirmDate = vdat(dtpbulkok.Value);
kayit.AccessoriesDate = vdat(dtpaccessory.Value);
kayit.AccessoriesArriveDate = vdat(dtpaccessoryarrive.Value);
kayit.ProductionStartConfirmation = vdat(dtpcutok.Value);
kayit.ProductionStart = vdat(dtpcutstart.Value);
kayit.ShipmentDate = vdat(dtpshipmentdate.Value);
kayit.ShipmentSampleDate = vdat(dtpshipmentsample.Value);
kayit.Shippedon = vdat(dtpshippedon.Value);
kayit.Status = true;
kayit.WrittenDate = DateTime.Now;
kayit.GuidKey = plu.GuidKey != null ? plu.GuidKey : Guid.NewGuid().ToString("N");
I have proven by breakpoint that values are actually same. But the != check retruns a true.
When you are doing
g != b
compiler doesn't know that these objects are strings to compare so it compares their references. You can do:
g.Equals(b) //be carefull if one of them is null
or
g.ToString() != b.ToString()
EDIT
You can compare them after you check the type:
if (g is string && b is string)
{
if( g.ToString() != b.ToString() ){
}
}
I have a client that retrieves a certificate (.pfx), including a private key, from a server and I add this to the local keychain with the following code: -
void AddCertToKeyChain(const QByteArray& cert, const QString& password)
{
SecKeychainRef keyChain = nil;
OSStatus err = SecKeychainCopyDomainDefault(kSecPreferencesDomainUser, &keyChain);
if (err != errSecSuccess)
{
emit Log("Failed to access system keychain: " + LogMessageForStatus(err));
return;
}
SecExternalFormat format = kSecFormatPKCS12;
SecExternalItemType itemType = kSecItemTypeAggregate;
SecItemImportExportFlags flags = 0;
SecItemImportExportKeyParameters params;
memset(¶ms, 0, sizeof(params));
params.version = SEC_KEY_IMPORT_EXPORT_PARAMS_VERSION;
params.flags = 0;
params.passphrase = password.toCFString();
params.alertTitle = NULL;
params.alertPrompt = NULL;
params.accessRef = NULL;
// create and populate the key usage array
CFMutableArrayRef keyUsage = CFArrayCreateMutable(
kCFAllocatorDefault,
0,
&kCFTypeArrayCallBacks
);
CFArrayAppendValue(keyUsage, kSecAttrCanEncrypt);
CFArrayAppendValue(keyUsage, kSecAttrCanDecrypt);
CFArrayAppendValue(keyUsage, kSecAttrCanDerive);
CFArrayAppendValue(keyUsage, kSecAttrCanSign);
CFArrayAppendValue(keyUsage, kSecAttrCanVerify);
CFArrayAppendValue(keyUsage, kSecAttrCanWrap);
CFArrayAppendValue(keyUsage, kSecAttrCanUnwrap);
keyUsage = NULL; // Error without this - Failed to import certificate: The key usage mask is not supported.
// create and populate the key attributes array
CFMutableArrayRef keyAttributes = CFArrayCreateMutable(
kCFAllocatorDefault, 0, &kCFTypeArrayCallBacks
);
// required for import
params.keyUsage = keyUsage;
params.keyAttributes = keyAttributes;
OSStatus status = SecItemImport(cert.toCFData(), CFSTR(".p12"), &format, &itemType, flags, ¶ms, keyChain, NULL);
if(status == errSecSuccess)
emit Log("Certificate successfully imported");
else
{
emit Log("Failed to import certificate: " + LogMessageForStatus(status));
}
}
The certificate and private key appear in the keychain, as expected.
However, trying to retrieve the certificate is a problem, either programmatically or using the Keychain application.
If I select to export the private key from the keychain, I'm provided with the following error in a dialog: -
"An error has occurred. Unable to export an item. The contents of this item cannot be retrieved"
However, if the certificate and key are added to the keychain by double-clicking on the pfx, exporting the key works as expected.
So, why would the code above cause the problem of not being able to export the key?
With the assistance of Quinn at Apple, It seems that the method described in the question should work, but doesn't.
Using an old CDSA style flag instead does in fact work, doing something like this: -
OSStatus err;
SecExternalFormat format;
SecItemImportExportKeyParameters params;
params.version = SEC_KEY_IMPORT_EXPORT_PARAMS_VERSION;
params.flags = 0;
params.passphrase = (__bridge CFStringRef) pkcs12Password;
params.alertTitle = NULL;
params.alertPrompt = NULL;
params.accessRef = NULL;
params.keyUsage = NULL;
params.keyAttributes = (__bridge CFArrayRef) #[ #(CSSM_KEYATTR_EXTRACTABLE) ];
format = kSecFormatPKCS12;
err = SecItemImport(
(__bridge CFDataRef) pkcs12Data,
CFSTR("p12"),
&format,
NULL,
0,
¶ms,
keychain,
NULL
);
Note the setting of params.keyAttributes, which defines the key to be extractable.
Alternatively, the older (deprecated) SecKeychainItemImport API may be used: -
BOOL success;
OSStatus err;
NSArray * result;
SecExternalFormat format;
SecKeyImportExportParameters params;
CFArrayRef importedItems;
result = nil;
importedItems = NULL;
format = kSecFormatPKCS12;
memset(¶ms, 0, sizeof(params));
params.passphrase = password;
params.keyAttributes = CSSM_KEYATTR_EXTRACTABLE;
err = SecKeychainItemImport(
(CFDataRef) pkcs12Blob, // importedData
NULL, // fileNameOrExtension
&format, // inputFormat
NULL, // itemType
0, // flags
¶ms, // keyParams
self->keychain, // importKeychain
&importedItems // outItems
);
success = (err == noErr);
While the function SecKeychainItemImport is defined as deprecated in Apple's documentation, I have been informed that it's unlikely to be removed any time soon.
I'm trying to create a simple addon for world of warcraft which records my kills.
I've already got'n quite far except there is a problem with the writing of a lua array.
The code I have so far
local CharacterDefaults = {
kills = {},
totalkills = 0
}
local killDefaults = {
DBtimeofday = 0,
DBplayer = 0,
DBenemyname = 0,
DBenemyid = 0,
DBzone = 0,
DBkilltype = 0
}
The next piece is inside a event which checks for overkill
if not KillCount then
KillCount = CharacterDefaults
end
if not KillCount.totalkills then
KillCount.totalkills = 0
end
KillCount.enemy[KillCount.totalkills] = destName
KillCount.kills[KillCount.totalkills] = killDefaults
KillCount.kills[KillCount.totalkills].DBtimeofday = stamp
KillCount.kills[KillCount.totalkills].DBzone = zone
KillCount.kills[KillCount.totalkills].DBkilltype = killtype
KillCount.kills[KillCount.totalkills].DBenemyid = unitId
KillCount.kills[KillCount.totalkills].DBenemyname = destName
KillCount.kills[KillCount.totalkills].DBplayer = playerName
KillCount.totalkills = KillCount.totalkills + 1
Ofcourse there's more code but this is the only important code (as far as I know).
If I look at this I would expect that for every new kill a new array part is made and the values are entered. However, for each kill I make in world of warcraft, every single item already in it will get the results of the last kill.
The lua variables saved file:
KillCount = {
["kills"] = {
{
["DBplayer"] = "MyName",
["DBzone"] = "Blackrock Depths",
["DBkilltype"] = 0,
["DBenemyname"] = "Grim Patron",
["DBenemyid"] = 9545,
["DBtimeofday"] = "11-09-22 10:45:23",
}, -- [1]
{
["DBplayer"] = "MyName",
["DBzone"] = "Blackrock Depths",
["DBkilltype"] = 0,
["DBenemyname"] = "Grim Patron",
["DBenemyid"] = 9545,
["DBtimeofday"] = "11-09-22 10:45:23",
}, -- [2]
[0] = {
["DBplayer"] = "MyName",
["DBzone"] = "Blackrock Depths",
["DBkilltype"] = 0,
["DBenemyname"] = "Grim Patron",
["DBenemyid"] = 9545,
["DBtimeofday"] = "11-09-22 10:45:23",
},
},
["totalkills"] = 3,
}
as you can see the [0] is the only one to be properly writen. Am I doing something wrong?
The problem is here:
KillCount.kills[KillCount.totalkills] = killDefaults
Everytime you kill, you're pointing KillCount.kills[KillCount.totalkills] to killDefaults then modifying killDefaults. The problem is, you are using the same killDefaults every time. So when you udpate the values of killDefaults later, it affects every reference to killDefaults that you have already created.
Try something like:
function GetDefaultKills()
return {
DBtimeofday = 0,
DBplayer = 0,
DBenemyname = 0,
DBenemyid = 0,
DBzone = 0,
DBkilltype = 0
};
end
KillCount.kills[KillCount.totalkills] = GetDefaultKills()
