I've got a program with a function that contains this line of code:
return Environment.GetFolderPath( Environment.SpecialFolder.Desktop );
that's the whole function. It's fine on my machine, but blowing up on the client, with an error about a root node being missing. Does anyone have any ideas ? He reckons it crashes on multiple machines. I have a try catch around the main function, that writes the call stack and error message to a log file.

Try using "DesktopDirectory" instead of "Desktop", i.e., try using the following code and see if it solves your problem:
return Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory);

Thanks, but I've discovered the error occurs in the boundary between one class and another ( see above) .How does the change you suggest differ from what I've done ?

"Desktop" is the logical Desktop rather than the physical file system location.
On the other hand, "DesktopDirectory" is the the directory used to physically store file objects on the desktop.
Therefore, one should not confuse this directory with the desktop folder itself, which is a virtual folder.

Thanks - that's a worthwhile change, although it stands no chance of fixing the problem at hand ( as far as I can see ). Live and learn...

Hi folks,
I need to write a piece of code to list all the virtual directories in IIS.
Could you guys give me a hint?

Is there a way to get the exact size of a process ? I've been looking at the Process class' members that deal with memory (PrivateMemorySize, PagedMemorySize, etc...) but none of them give me the same number as Task Manager does. Anyone know how to get the exact size of a running process ? Thanks in advance...

Nevermind I've found it. It's (Process.WorkingSet / 1024).

I am using Visual C# 2005 to develop a program. When the program calls line 3 of the following code I get a COMException with every path I try. I am trying to place a shortcut in the start menu.
The problem code is underlined. Even when that method is called by itself it creates the exception. I have included the proper reference in the project. Any ideas? Thanks for any help.
WshShell shell = new WshShell();
string path = Environment.GetFolderPath(Environment.SpecialFolder.StartMenu) + "\\programs";
IWshShortcut link = (IWshShortcut)shell.CreateShortcut(path);
link.TargetPath = destinationPath + "\\filemover.exe";
link.IconLocation = destinationPath + "\\" + "FileMover.ico";
link.Save();

Question #1: Event Handler External to the Main Form
An application that I am working on requires an eventhandler class stored in another folder separate from the main application form. The problem that this creates is that I have been forced to have two event handler approaches for the controls: one for the event processing and another to manipulate the form controls. I would much rather prefer to combine the two event handlers into one event handler to remove the confusion rather than have to manage two of them.
The reason why I cannot put all of the code thus far into the external event handler is because none of the form objects are available in the external event handler class. In other words, I would need to manipulate elements that are on the form from the external event handler. However, the external event handler does not even permit the keyword "this" to be used, especially when the methods in the external event handler is set to static. If the keyword static is removed, then the keyword "this" works, but only for the elements that are on the external event handler class. I cannot manipulate any of the form elements from the external event handler class.
The first question is: How to I address the main form of the application from the external event handler class. I tried to use:
<br />
frmMainForm frm = new frmMainForm();<br />
but that only created another form. When I tried to manipulate the controls on the form, and the event handler interacted with this "new" form, it caused the form controls to disappear. I suspect that the control disappeared from the original form because it did not know what to do with it, considering that now there was a "new" frmMainForm form. Either that or it actually attempted to move the control from the "original" frmMainForm to the "new" frmMainForm, but I doubt it because that would require some other technologies.
I also used the "using" keyword referencing the namespace of the frmMainForm form. Then where the code required the frmMainForm I tried to reference it with
<br />
System.Windows.Forms.Form frm = NameSpaceOfFrmMainForm.frmMainForm.ActiveForm;<br />
but when the program reached this line of code, it only caused the form to become "active" thereby ignoring any of the code following it which attempted to use the form controls from the application's main form. I know that I am missing something. Could somebody kindly explain to me how to address the application's main form from an external event handler class?
Question #2: ctrl.Update()
When drawing a control to the screen in a looping construction of an array, I would like to clean the screen from the previous iteration through the loop. For example:
<br />
System.Drawing.Point pt1 = new ctrl.Location(50, 10);<br />
System.Drawing.Point pt2 = new ctrl.Location(50, 20);<br />
System.Drawing.Point pt3 = new ctrl.Location(50, 30);<br />
System.Drawing.Point pt4 = new ctrl.Location(50, 40);<br />
<br />
Point[] ptArray = {pt1, pt2, pt3, pt4};<br />
foreach (Point pt in ptArray)<br />
{<br />
ctrl.Location = pt;<br />
ctrl.Update();<br />
}<br />
The problem is that each time through the array loop, the control displays, but the previous time through the loop is not removed. Is there some kind of Form1.Paint() delegate that could be used to clear the previous control image ghost? I would like the control to appear as if it is moving with an animation effect, but the fact that the previous ctrl.Update() remains on each next time through the loop detracts from the desired result. Would really appreciate some assistance!!!

Because every time you do a complete rebuild of the application, the output directories get cleaned out. You might want to try putting the .INI file either in the application project folder or where the application can find it on the Path, like in the %WINDIR% folder, which, BTW, is not always C:\WINDOWS.
By putting it in the application project folder, this folder will not get cleaned out when you rebuild your project. If your code is written correctly, it will not assume that the current directory is whatever directory the app was launched from. Instead, your code should ask the system from what directory is was launched from, then look in the directory for the configuration file.
Check into storing Application.StartupPath and/or Environment.CurrentDirectory when your application starts and using it later to locate your configuration file.

hi
I want to use the .exe.config file. I copied to the main project folder. Then also it is not reading the file. Please tell me from where all the application reads the exe.config file. Secondly, I created an .ini file also.
I copied .ini file to bin, debug and project folder. I set the project output folder to first to bin then to debug. But the problem remains.
please help

Actually this is not true. I have multiple applications that have INI files in the Debug & Release directories and they are not effected in any way when performing any build type in the build menu of VS.NET. Are you talking about some action other than those in the build menu ?
