I have a file stored in local computer and a printer connected too. So generally if I want to give a print of the file to the connected printer, I would run following command in command prompt:
cd <path where the file is locally stored>
copy <filename.ext> <portname in which the printer is connected>
So for example, if I have a file at path /Users/chandrani.chatterjee/Desktop/TestFolder and a printer connected at port lpt1 I would write following commands in command prompt
cd /Users/chandrani.chatterjee/Desktop/TestFolder
copy testfilename.txt lpt1
So this would print my testfilename.txt
No I want to achieve this on a button click in ReactJs.
I searched the web and found out about shellJs but I am not sure on how to fire the commands using it.
I tried
var sh = require('shelljs');
const { stdout, stderr, code } = sh.exec('cd /Users/chandrani.chatterjee/Desktop/TestFolder', { silent: true });
I also tried
var sh = require('shelljs');
var output = sh.exec('java -version', {silent:true}).stdout;
but getting error in both the scenarios
Cannot read property 'stdout' of null
How to do this correctly?
EDIT:
For example in .Net the same can be achieved with below code:
function create_send_file() {
var fso = new ActiveXObject("Scripting.FileSystemObject");
var s = fso.CreateTextFile("c:\\FilePrn\\label.prn", true);
s.WriteLine("some string");
s.Close();
var newpath = fso.CopyFile("c:\\FilePrn\\label.prn", "lpt1");
}
Your Reactapp is running in the browser so doesn't have access to your shell.
To do this you will need to create a web service that React app can call to. Here you can execute the shell command return the result to the React in the browser.

I created an application in VS2010 with operating system WINDOWS XP.
Now, I updated the os to WIN 7 and also updated the location of the application.
So, while running the application for opening a file using open dialog box it showing some exception like"File Not Found".
It was working fine with WIN XP, but now it showing this error, if we keep that perticular file in bin folder its working fine , but if we choose a file from other drive or a folder it showing error.
enter code here
string chosen_file = "";
ofd.Title = "Open a file";
ofd.FileName = "";
ofd.Filter = "Text Files(*.txt)|*.txt|Rich Text Box(*.rtb)|*.rtb|Word Document(*.doc)|*.doc|HTML Pages(*.htm)|*.html|Cascading Style Sheet(*.css)|*.css|JAVA(*.java)|*.java|video file(*.wmv)|*.wmv|All Files(*.*)|*.*";
if (ofd.ShowDialog() == DialogResult.OK)
{
chosen_file = ofd.FileName;
// richTextBox2.LoadFile(chosen_file, RichTextBoxStreamType.PlainText);
var fileInfo = new FileInfo(ofd.FileName);
fileInfo.Length.ToString();
byte[] buffer = new byte[fileInfo.Length];
int length = (int)fileInfo.Length;
FileStream fileStream = new FileStream(fileInfo.Name, FileMode.Open, FileAccess.Read);
fileStream.Read(buffer, 0, length);}
My guess is you referenced a hard-coded path, probably to your "Documents" folder, rather than using an environment variable. With the change from XP to 7, that directory changed. I can't recall what the directory was for Windows XP, but it's now /users/username for Windows 7. Either way, you would be better off using an environment variable.
Look through your program for Documents and Settings and see if you can find it. If you go to a command prompt and type set, it should give you a list of environment variables you could use in place of whatever you were using.
I have been trying to get the Neustar Local-Validator working on my Windows 7 machine however I keep getting "SocketException : Connection Reset". Does anyone have any experience with this?
Even a very simple script is failing:
var driver = test.openBrowser();
var selenium = driver.getSelenium();
var timeout = 120000;
selenium.setTimeout(timeout);
var tx = test.beginTransaction();
var step = test.beginStep("Homepage", timeout);
selenium.open("http://www.neustar.biz/");
test.endStep();
test.endTransaction();
It sounds like you might not have the config file setup correctly for your machine.
Update the file C:\Users\%USERNAME%\.wpm\config.properties
An example is below, but you will want to use the correct path based on your machine.
FF=C:\\Program\ Files\ (x86)\\Mozilla\ Firefox\\firefox.exe
I have an AIR-app and I want it to write down logs to a txt file in its application directory.
I have this class:
public class Logger
{
public static function log(message:String):void
{
var logFile:File = File.applicationDirectory;
logFile = logFile.resolvePath("log/Logs.txt");
var fileStream:FileStream = new FileStream();
fileStream.open(logFile, FileMode.APPEND);
fileStream.writeUTFBytes("\n" + message);
fileStream.close();
}
}
}
After installation my app has this file structure
log
--Logs.txt
META-INF
xml
airapp.exe
airapp.swf
mimetype
So the path I'm using is correct.
But no writes happen to the file!
Could you help me with that please?
Thanks
Upd. Ok, I'm stupid. I should have read documentation properly first.
You cannot edit data in application directory.
So I should use applicationStorageDirectory.
But how can I create a file in that directory once (on app installation) and then append logs in it?
Try the following....
function saveLog(logStr:String):void
{
var myFile:File = File.applicationStorageDirectory.resolvePath("my_logs.txt");
var fs:FileStream = new FileStream();
if(!myFile.exists){
fs.open(myFile, FileMode.WRITE);
}
else{
fs.open(myFile, FileMode.APPEND);
}
fs.writeUTFBytes("\n" + logStr);
fs.close();
}
call this function on creation complete and then from where to add logs.
If you want the real log than you should use third party installer rather than native run time of adobe air. Try Wixedit(opensource) or install aware .
You have to export your project into captive run time format that is provided in flash builder.
try this link
http://www.adobe.com/devnet/air/articles/customize-setup-for-AIR-app-with-captive-runtime.html
Try something like:
function saveLog(content:String):void
{
var data:ByteArray = new ByteArray();
data.writeMultiByte(content, "utf-8");
file.save(data, "Logs.txt");
}
saveLog('testing :)');
To open and edit your log file, try to follow this tutorial
Im writing WPF application and want to add ability to call jump list and open program configuration, app.config or log directory from it. Is it possible(cant find the way to do that..just JumpTasks with application path and JumpPath with path to file, and not just path to be opened via explorer)?
Found answer here. Seems that JumpList wasnt designed for opening anything but files or applications, associated with current program. So that when we see directories in explorer tasklist -it actually means: use explorer with parameters. By the way ill try to use it.
Update
made it with such code:
string explorerPath = #"%windir%\explorer.exe";
JumpTask path = new JumpTask
{
CustomCategory = "Paths",
Title = "Open program directory",
IconResourcePath = explorerPath,
ApplicationPath = explorerPath,
Arguments = #"/root," + AppDomain.CurrentDomain.BaseDirectory,
Description = AppDomain.CurrentDomain.BaseDirectory
};
Im leaving this answer here, because someone can have similar incomprehension.
I want to create a web application similar to TS Web Access, where I can create rdp files on the fly for Remote Apps configured on the server. Any idea??
We had to do this exact thing.
private void InvokeRDPSign(String fileName, String certificateThumbPrint)
{
Process signingProcess = new Process();
signingProcess.StartInfo.FileName = #"rdpsign.exe";
String arguments = String.Format("/sha1 {0} {1}", certificateThumbPrint, fileName);
signingProcess.StartInfo.Arguments = arguments;
signingProcess.StartInfo.UseShellExecute = false;
signingProcess.StartInfo.RedirectStandardOutput = true;
signingProcess.StartInfo.WorkingDirectory = Environment.SystemDirectory;
signingProcess.Start();
String signingOutput = signingProcess.StandardOutput.ReadToEnd();
signingProcess.WaitForExit();
int exitCode = signingProcess.ExitCode;
//TODO: should we throw an error if the exitcode is not 0
}
Be aware that that the RDPSign.exe is different on each version of windows. You will find that an older version of the utility will ignore newer settings from the signature.
well Having looked at a 'rdp' file this is the contents:
screen mode id:i:2
desktopwidth:i:1280
desktopheight:i:768
session bpp:i:32
winposstr:s:2,3,1430,104,2230,704

keyboardhook:i:2

shell working directory:s:
gatewayhostname:s:
gatewayusagemethod:i:4
gatewaycredentialssource:i:4

Just create that as a string, seems straightforward.
ps I have no idea what the 'winposstr' parameter is...
