App. works in Debug mode but not Release

[michael_hk]

Hi guys,

 

I have developed a simple remoting app. It works fine in Debug mode, but when I want to run it in Release mode (press F5), it gives

 

The parameter is incorrect

 

when I call a method.

 

How is going on? :confused: :confused:

 

Thanks for your time.

Could you post the relevant code? It makes it a lot harder to solve a problem when people have to guess what the calling and server code looks like.

The following code works in debug mode.

 

Client:

txtResult.Text = infoMan.getUserList(txtUserName.Text);

 

Server:

public string getUserList(string userName)
{
try
{
	System.Diagnostics.ProcessStartInfo ps = new System.Diagnostics.ProcessStartInfo();
	ps.FileName = @"C:\USERLIST.EXE";			ps.Arguments= userName;		
	ps.RedirectStandardOutput=true;
	System.Diagnostics.Process p = new System.Diagnostics.Process();
	ps.UseShellExecute=false;
	p.StartInfo=ps;
	p.Start();
	string s = p.StandardOutput.ReadToEnd();
	return s;
}
catch (Exception ex)
{
	return ex.Message;
}
}

Is it failing on the client's call to the server or somwhere within the server code? If on the server do you know which line of code is failing?

I really have no idea.....

 

After the call, infoMan.getUserList(txtUserName.Text), the textbox (txtResult) shows

 

"The parameter is incorrect"

 

The strange thing is the above sentence is not produced by an exception.

 

i.e. the following code

 

catch (Exception ex)
{
return ex.Message;
}

 

has never been executed.

If you change the server's exception handler to return something else does that really not change the contents of the label?

i.e.

catch (Exception ex)
{
return ex.Message + ' ' + "test";
}

God......the contents changed now......So I can firm it is an exception. :p

 

But still don't know why it is an exception in Release mode, but not in Debug mode.

If you enable debug symbols on your release build and return ex.ToString() what line of code does it point to on the server code?
