I believe you need to use your config files for that. REsources are part of the exe, you can't change them

Resource files don't exist at runtime. They're compiled into the .EXE and the resources are readonly since you cannot modify an .EXE file while it's running.

Hi,
I am working on C# form application. The user can change the UI seetings and i need to restart the application.
I am using Application.Restart() method to do this.
But this is not closing my MainThread (Form) completely.
To ensure that only one instance of appplication should be running, i am checking for the process name like this:
string MyMainProcessName = Process.GetCurrentProcess().ProcessName;
Process[] AppInstances = Process.GetProcessesByName(MyMainProcessName );
if (AppInstances .Length > GlobalConstants.ONE)
{
MessageBox.Show("The application is already running");
}
I always get this message whenever i restart the application.
How to ensure that Main Application and all child applcation should be terminated properly before doing Restart?
Thanks.

Where are you checking if another instance already exists? Surely you are doing it in the Main() method, before you show the form? I just created a small app with a restart button that does not allow multiple instances and it works perfectly fine.

Yes.
I check for this just in the beginning of Main(..)
My application UI is having lots controls placed in it also having some other child thread which also needs to be closed.
But the restart doesn't wait till all these terminates properly.
How do i make sure the Restart should wait till all the processes are closed properly?

That is somewhat hard to believe, although it's possible. What do you do with the other threads when you restart the app?
Have you tried setting a breakpoint where you do the multiple-instance check? How many process instances does it say there are?
Cheers,
Vikram.

Thanks Vikram.
It's true about Restart()
Anyway, i set a flag in my application's main form and in Main.cs i check this flag. If it is true then i restart the application. Like this in Main.cs:
Application.Run(gObjfrmMDIMain);
//If application needs to be restarted
if(MyMainFormObj.IsApplicationRestarted)
{
MyMainFormObj.IsApplicationRestarted= false;
Application.Restart();
}
Just before Application.Restart(), i want to make sure that MyMainFormObj has been disposed properly or i want to wait till it is getting done.
The problem is the Application.Restart() starts the application in without debug mode so no use of breakpoint over there. I tried displaying the messageBox and it says about the instance already running.

Whoops, I didn't think about that. You will not be able to use a flag across different instances of the app, so no luck there.
Have you tried using a Mutex? That's what I use to avoid multiple instances - maybe you can have the mutex wait for a while before you decide not to proceed?
I'm at home now; I don't have the code sample. I could send it tomorrow if you want....

Vikram.

Restart first starts a new instance of the application and then exits the existing instance.
If it would exit first, no one would be left to start the new instance.
|
|
|
|

Thanks Daniel,
But it doesn't always give the similar result. Some time it terminates properly but someting the instance still exist.
Most of the time if you are already in restarted application and you restart it again then it occurs more frequently.

I have encountered a typical problem while splitting a large file(.doc) in C# and then sending them via email. After splitting the files when I try to send them in email as attachment always the first part is not received at the destination ie if a file is split into 5 parts(part0,part1...part4) then the part0 is never received but is successfully sent.
I have even tried this with the file splitter program available in codeproject.
Any help would be appreciated?
|
|
|
|
|
One more update on this is when I use normal C program to split the files, all of them are received at the destination.

How do you expect people to help you if they can't see what you are doing? Showing the relevant code would go a long way here.
Cheers,

Also, this is happening only for .doc files.

hello,
im trying to write in process memory(of a game)at a specified address, but its not working, neither any error nor working, im new to API.
here is the code im using to write a int(4 bytes) value at 0xB7CE50.
IntPtr m_hProcess = IntPtr.Zero;
m_hProcess = APIDecalaration.OpenProcess(APIDecalaration.PROCESS_ALL_ACCESS, 1, ((UInt32)MYProcesses[0].Id));
APIDecalaration.WriteProcessMemory(m_hProcess, (IntPtr)0xB7CE50, 1000, 4, 0);
int isClosed = APIDecalaration.CloseHandle(m_hProcess);
if (isClosed == 0)
throw (new Exception("CloseHandle failed"));
APIDecalaration class :
public const int PROCESS_ALL_ACCESS = 0x1F0FFF;
[DllImport("kernel32", ExactSpelling = true, CharSet = CharSet.Ansi, SetLastError = true)]
public static extern IntPtr OpenProcess(UInt32 dwDesiredAccess, int bInheritHandle, UInt32 dwProcessId);
[DllImport("kernel32", ExactSpelling = true, CharSet = CharSet.Ansi, SetLastError = true)]
public static extern int WriteProcessMemory(IntPtr hProcess, IntPtr lpBaseAddress, int lpBuffer, long nSize, long lpNumberOfBytesWritten);
[DllImport("kernel32", ExactSpelling = true, CharSet = CharSet.Ansi, SetLastError = true)]
public static extern int CloseHandle(IntPtr hObject);
where i did mistake ???

I have a C# Form textBox that I would like to display a global counter that keeps track of different events. I would like to lock down the textBox so no input can be entered. Does anyone have an example of how to do this or a example of a better way of displaying this counter.
|
|
|
|
|
Hi
can can, You create a global property for the counter. and create a custom event for every evetn fiare in the any of the ur form trigger ur custom event and update the textbox by the ur counter value.
Basically u create a text box property readonly=true.
|
|
|
|
|
A TextBox has a ReadOnly property which you have to set to false. You could use a Label, but a TextBox is better because it still allows the user to copy-paste the contents.

Vikram.

Hi all,
i need set the position for ascii char in richtextbox.
Here is my coding that will show the ascii char in richtextbox.
string hex = "040";
string hex1 = "025";
string hex2 = "023";
string hex3 = "025";
int code = Convert.ToInt32(hex,16);
int code1 = Convert.ToInt32(hex1,16);
int code2 = Convert.ToInt32(hex2,16);
int code3 = Convert.ToInt32(hex3, 16);
richTextBox1.Text = Encoding.Default.GetString(new byte[] {(byte)code,(byte)code1,(byte)code2,(byte)code3});
Now i need arrange all the ascii char in correct position.I hd tried in many ways,but still got errors.pls help me.
Thank you.
