That's not what he meant. He meant to check something like this:
var msg = Message;
if (msg == null)
{
}
var field = msg.GetField("FieldName", 0);
if (field == null)
{
}
var value = field.Value;

Hello everybody,
The GetWindowText Function is not working fine if my selected application title is
मेरी थकन or Something like that.
If you can think then I Can.

|

How have you defined GetWindowText? What does your import look like?
|
|
|
|
|
Dear Sir,
Actually GetWindowText is a Native Api
Private Declare Function GetWindowText Lib "user32" Alias "GetWindowTextA" (ByVal hwnd As Integer, ByVal lpString As String, ByVal cch As Integer) As Integer
If you can think then I Can.

You should be using the Unicode version GetWindowTextW().

Dear Sir,
Thanks for reply and Answer.
But i don't know how to use GetWindowTextW in C#.
Can u please describe me how to Use GetWindowTextW in the place of GetWindowText.

They are exactly the same, except that GetWindowTextW() returns its data in Unicode, so it works for C#. See here[^] for the formal specification.

I know it is. I needed to see the function definition, which you for some reason have provided in VB. Specifically I wanted to see what your CharSet was set to.

Hello,
I want to execute a command line command from my C#. I have written code that works but am not as expected. The code is taken from "How to Execute a Command in C# ?" found on this site. and is :
<code>
public static int ExecuteCommand(string Command, int Timeout)
{
int ExitCode = -1;
ProcessStartInfo ProcessInfo;
Process Process;
try
{
ProcessInfo = new ProcessStartInfo("cmd.exe", "/C " + Command);
ProcessInfo.UseShellExecute = false;
ProcessInfo.RedirectStandardOutput = true;
//ProcessInfo.CreateNoWindow = false;
//ProcessInfo.UseShellExecute = false;
Process = Process.Start(ProcessInfo);
// Get the results
string result = Process.StandardOutput.ReadToEnd();
Console.WriteLine("Process Result = " + result);
Process.WaitForExit();
ExitCode = Process.ExitCode;
Console.WriteLine("%%%%%%%%%%% EXIT CODE = " + ExitCode);
Process.Close();
}
catch (Exception e) {
Console.WriteLine("Error Processing ExecuteCommand : " + e.Message);
}
finally {
//Process = null;
//ProcessInfo = null;
}
return ExitCode;
}
</code>
The code runs, but untill I don't press "Ctrl+C" on dos prompt I don't see any results. I also want to check a line form the console text. For eg: If I find "Connected" from the output I want to close the process and return. Then when the user asks for disconnecting want to execute another command to disconnect the running application.
Why does the above code doesn't retun untill I press "Ctrl+c" on the command window (I don't want to show the command window also, right now am just showing)? Whne I press Ctrl+C I see the text on Console (output window), but want to check the text and on findling "Connected" want ot return and/or close the process.
Can anyone point out where am I going wrong and how to solve the problem and work out with it.
Any help is highly appreciated. Need to solve this early have already spend 2-3 days trying to solve the problem.
Thanks
Thanks & Regards,

Hi,
I want to restrict users log on the computer from Windows "Guest" account from starting our application. Our application can be used on XP, Vista and Windows 7.
What is wrong with this solution, I get SecurityException when testing from Win7 guest account, I have tried both PrincipalPermission(null, "Guests"); and PrincipalPermission(null, "Guest");
I have also tried to use PrincipalPermission(null, "Administrators"); and then I can use the application from Admin account but not from guest account.
static void Main()
{
AppDomain.CurrentDomain.SetPrincipalPolicy(PrincipalPolicy.WindowsPrincipal);
PrincipalPermission principalGuest = new PrincipalPermission(null, "Guest"); //Has also tested with "Guests"
try
{
principalGuest.Demand();
}
catch (SecurityException e)
{
//I only want to get this exception if the user is Windows account type "guest"
}
}
Best regards
Olof

have you tried?
WindowsIdentity wi = WindowsIdentity.GetCurrent();
WindowsPrincipal wp = new WindowsPrincipal(wi);
if (wp.IsInRole(WindowsBuiltInRole.Guest)) return;
Might need a bit more code but that should help
Architecture is extensible, code is minimal.

Hi, thanks for your answer. With this solution I can block users that belong to the Windows Guest group. I want to block user with name guest. The guest account you can turn on/off on windows.
I got an answer on another forum
string username = Environment.UserName;
if (username.ToLower() == "guest")
Application.Exit();
One problem is that the application can be used on many different language OS, if we are using chinese OS do we have to translate "guest" to chinese before or is there another way to determine this?
We can translate "guest" but it is easy if there is another way to solve it.

You'll need to create globalization resource files. There are a number of articles [here] at CodeProject
BTW: You'll be doing the support desk a favour if you add a MessageBox notifying "Guest" that they have insufficient permissions to use the application before exiting.

Looks like you don't want to "inject" code, but read the memory of a foreign process. There's an article[^] on that

Ooh, thank you. I'll test that tonight.

Ok, I have just about had enough...
Two systems, one laptop one desktop.
Built the same small test app on each one. Just a button that when clicked writes the following:
Debug.WriteLine("Test");
The laptop writes the 'Test' out tothe debug window just fine... the desktop doe snot.
Ready to really throw a fit here...
Any ideas before I toss things out the window?
Aaaaaaaaaaaaaaaaaaa

Hi Ray,
with the risk to state the obvious: the Debug class only works in a debug build. Check your "Configuration Manager". And check your project properties: in the Build pane, there may be a checkbox "define DEBUG constant" which should be checked.

Looks good to me... I even changed my setting over to release, ran it and then went back to debug and reran it thinking maybe there was a corrupted configuration or something...
No luck...

You could replace Debug.WriteLine by Console.WriteLine just to test the statement is reached...
