I am building a money budgeting app where the user can split their monthly salary in 5 areas: food, social, education, travel, savings. I have a register and log in screen. This is in Flutter/dart and I'm using sqlite.
Some of the data to store:
id, username, password, email, monthly_salary, food_initial, food_final, social_initial, social_final, education_initial, education_final, travel_initial, travel_final, savings_initial, savings_final
The 'initial' refers to a value that the user will input for themselves based on the division of the monthly salary. (ie. $5000 a month/5 containers = 1000 for each container. but, the user can edit this value of 1000 as their initial budgeted money). The 'final' refers to the user's remaining money (under the assumption they don't go over) for that container.
The initial and final values get reset at the end of the month. However, I would like to save their previous month's final values so the user can see a backlog of what they did.
I initially had 2 tables for my database. One was for the USER_DATA and the other was BUDGETS table. However, after struggling to figure out how to do CRUD operations for two tables, I decided to make it all into one table. But, after experiencing trouble with one table, I want to move back to more than one table. I'm confused now on:
1. How to use CRUD operations when having more than one table on DB?
2. Do I have to build a new model class in order to have more than one table?
3. How to save some of the user's data on database, but have to wait for the rest of the information to come in (later on while they're using the app)?
When making the constructor for the model class, and then referring to the model class in the UI, it requires me to bring in all of the parameters I have, but I don't have all of those values ready yet. The user still needs to register before they can input their salary and etc. Would I have to use the Future class to get over this hurdle?
I've watched a lot of videos on others building their databases in sqlite and with Flutter but all of them usually do a simple To-Do list app where they will need to fill in every column of the table and I haven't seen one yet that includes several tables. (ie. columns: id, description, priority, date)
--
I think have a good basis now on the UI side and using TextFormFields to access the information, but connecting the database/creating it properly is confusing me.
I am also considering writing the database in a .sql file now before proceeding. I have been teaching myself Flutter through tutorials (as background knowledge).
I know this is a bit long and all over the place, but I would greatly appreciate anyone who has experience with the sqlite environment in Flutter to please help me understand how to do this correctly.
Thank you. Also, if there is any more clarification/code needed, let me know.

To be more specific, I am confused on not writing the query of a new table, but rather at this point:
var result = await db.insert(userDataTable, data.toMap());
return result;
The result is only containing my userDataTable and if I create another table, then am I supposed to add another var result? I tried to have:
var result2 = await db.insert(budgetsTable, data.toMap());
This seemed wrong. Also, I didn't know how to return both results.
That was specifically where/when I started to scavenge the internet of people who have made CRUD operations using more than one table on sqlite with Flutter.
I have this function which get back longitude and latitude from my Rtb data (first picture):
// funkcja pobierająca szerokość i długość geograficzną w formacie dziesiętnym
private Tuple<double, double>[] wsp_geograficzne(string[] lines)
{
return Array.ConvertAll(lines, line =>
{
string[] elems = line.Split(',');
return new Tuple<double, double>(0.01*double.Parse(elems[1]), 0.01*double.Parse(elems[3]));
});
}
This line calls this above function:
var data = wsp_geograficzne(richTextBox1.Lines);
This is a sample, which display routes on my OpenStreetMaps.
GMapOverlay routes = new GMapOverlay(gMapControl1, "routes");// Constructing object for Overlay
gMapControl1.Overlays.Add(routes);
List<PointLatLng> list = new List<PointLatLng>(); // The list of Coordinates to be plotted
list.Add(new PointLatLng(53.119149707703, 23.1447064876556));
list.Add(new PointLatLng(53.11963262556597, 23.1468522548676));
list.Add(new PointLatLng(53.1205276192621, 23.1460046768188));
list.Add(new PointLatLng(53.120701464779, 23.1463050842285));
list.Add(new PointLatLng(53.1200962217943, 23.1489872932434));
list.Add(new PointLatLng(53.1196970143107, 23.1489014625549));
list.Add(new PointLatLng(53.119439459128, 23.1490087509155));
GMapRoute r = new GMapRoute(list, "myroute"); // object for routing
r.Stroke.Width = 5;
r.Stroke.Color = Color.Blue;
routes.Routes.Add(r);
gMapControl1.ZoomAndCenterRoute(r);
gMapControl1.Zoom = 15;
It looks like on the picture:
I want display routes from my data "wsp_geograficzne" (wsp_geograficzne include longitude and latitude) on this map. How should I do it? Is there any method that allow me to create List which data from "wsp_geograficzne"? I trying something like this:
List<PointLatLng> nowa = new List<PointLatLng>();
foreach (var p in data)
nowa.Add(p.Item1, p.Item2);
but it dont works. I get back error: Error 2 No overload for method 'Add' takes 2 arguments.
Please help :)
Ok I find answer (new function which get back 2 value (longitude and latitude) from rtb (longitude and latitude are back in decimal notation):
// funkcja pobierająca szerokość i długość geograficzną w formacie dziesiętnym
private Tuple<double, double>[] wsp_geograficzne(string[] lines)
{
return Array.ConvertAll(lines, line =>
{
string[] elems = line.Split(',');
double we1 = 0.01 * double.Parse(elems[3], EnglishCulture);
int stopnie1 = (int)we1;
double minuty1 = ((we1 - stopnie1) * 100) / 60;
double szerokosc_dziesietna = stopnie1 + minuty1;
double we2 = 0.01 * double.Parse(elems[5], EnglishCulture);
int stopnie2 = (int)we2;
double minuty2 = ((we2 - stopnie2) * 100) / 60;
double dlugosc_dziesietna = stopnie2 + minuty2;
return new Tuple<double, double>(szerokosc_dziesietna, dlugosc_dziesietna);
});
}
And this is a part which display routes on the map.
{
var data = wsp_geograficzne(richTextBox1.Lines);
List<PointLatLng> nowa = new List<PointLatLng>();
foreach (var p in data)
nowa.Add(new PointLatLng(p.Item1, p.Item2));
GMapOverlay routes = new GMapOverlay(gMapControl1, "routes");
gMapControl1.Overlays.Add(routes);
GMapRoute r = new GMapRoute(nowa, "myroute"); // object for routing
r.Stroke.Width = 9;
r.Stroke.Color = Color.Blue;
routes.Routes.Add(r);
gMapControl1.ZoomAndCenterRoute(r);
gMapControl1.Zoom = 16;
}
If someone has another notations this part:
List<PointLatLng> nowa = new List<PointLatLng>();
foreach (var p in data)
nowa.Add(new PointLatLng(p.Item1, p.Item2));
please show me here.
Greetings from Poland :).
I am creating a silverlight application as a web resource for CRM 2011. Now i am creating a ServiceAppointment record in DB and after creating it i want to change its Status to "reserved" instead of requested.
I googled about this and come across the examples like Close a Service Activity Through Code and Microsoft.Crm.Sdk.Messages.SetStateRequest
They all suggesting to use "SetStateRequest" and for using this i have to set the OptionSetValue like
request["State"] = new OptionSetValue(4);
But above line gives me error saying "OptionSetValue does not contain constructor which takes one argument"
BTW i am using SOAP end point of CRM 2011 service in silverlight application
Any ideas friends?
EDIT
Following is my code
var request = new OrganizationRequest { RequestName = "SetStateRequest" };
request["State"] = 3;
request["Status"] = 4;
request["EntityMoniker"] = new EntityReference() { Id = createdActivityId, LogicalName = "serviceappointment" };
crmService.BeginExecute(request,ChangeActivityStatusCallback,crmService);
And my callback function is
private void ChangeActivityStatusCallback(IAsyncResult result) {
OrganizationResponse response;
try
{
response = ((IOrganizationService)result.AsyncState).EndExecute(result);
}
catch (Exception ex)
{
_syncContext.Send(ShowError, ex);
return;
}
}
You must some how be referencing some other OptionSetValue class that is not the Microsoft.Xrm.Sdk one. Try appending the namespace to see if that resolves your issue:
request["State"] = new Microsoft.Xrm.Sdk.OptionSetValue(4);
Also, why are you using late bound on the SetStateRequest? Just use the SetStateRequest class:
public static Microsoft.Crm.Sdk.Messages.SetStateResponse SetState(this IOrganizationService service,
Entity entity, int state, int? status)
{
var setStateReq = new Microsoft.Crm.Sdk.Messages.SetStateRequest();
setStateReq.EntityMoniker = entity.ToEntityReference();
setStateReq.State = new OptionSetValue(state);
setStateReq.Status = new OptionSetValue(status ?? -1);
return (Microsoft.Crm.Sdk.Messages.SetStateResponse)service.Execute(setStateReq);
}
Thanks Daryl for you time and effort. I have solved my problem with the way u have suggested.
I am posting my code that worked for me.
var request = new OrganizationRequest { RequestName = "SetState" };
request["State"] = new OptionSetValue { Value = 3 };
request["Status"] = new OptionSetValue { Value = 4 };
request["EntityMoniker"] = new EntityReference() { Id = createdActivityId, LogicalName = "serviceappointment" };
crmService.BeginExecute(request,ChangeActivityStatusCallback,crmService);
private void ChangeActivityStatusCallback(IAsyncResult result) {
OrganizationResponse response;
try
{
response = ((IOrganizationService)result.AsyncState).EndExecute(result);
}
catch (Exception ex)
{
_syncContext.Send(ShowError, ex);
return;
}
}

oUser.Profile.ProfileProperties.Add(def);
}
oUser.Profile.SetProfileProperty("Level", ddlLevel.SelectedItem.Text.ToString().Trim());
DotNetNuke.Entities.Profile.ProfileController.UpdateUserProfile(oUser, oUser.Profile.ProfileProperties);
But it won't work, please help me with suitable solution.
try out this code for adding Profile Property:

I am using Nevron Charting Control ver.11.1.17.12 in application. I am facing problem in drawing the chart correct with the DateTimeScaleConfigurator. Here are following problem:
Series Bar overlapping each other if series count increases.
Series getting out of the Axis lines.
X Axis Scale automatically add previous year December and next year Jan in the scale which cause the chart to have blank area in case of Surface Chart.

Here is the generated output:
Any idea regarding this problem will be deeply appreciated.
Thanks in advance.
Series Bar overlapping each other if series count increases.
&
Series bar getting out of the Axis lines.
Answer: When you are using categorial data then use NOrdinalScaleConfigurator rather than NDateTimeScaleConfigurator. It will not solve the problem and put the series bar in the center of the scale and auto resize them according to the chart size also.
X Axis Scale automatically add previous year December and next year
Jan in the scale which cause the chart to have blank area in case of
Surface Chart.
Answer:
Set the following properties of the DateTimeScaleConfigurator to false to avoid such behavior.
dateTimeScale.RoundToTickMax = false;
dateTimeScale.RoundToTickMin = false;
