Hi,

I'm trying to get the complete path of all .exe returned by
Process.GetProcesses()

The problem is the "theprocess.MainModule.FileName"...sometime for
some process it return stange invalid path like this : \??\c:
\blablabla\myexe.exe

Is there any other way to get the correct path (without the \??\)

Here is the code :
//...
using System.Diagnostics;
//...
Process[] processlist = Process.GetProcesses();
foreach (Process theprocess in processlist)
{

MessageBox.Show(theprocess.MainModule.FileName);

}

Thanks!
 
Hi,

The prefix on the path that you are probably talking about is \\?\ and it is
a perfectly valid prefix for a path.

Check out the following link on MSDN for more information. Specifically,
pay attention to the section titled "Maximum Path Length".

Hope this helps,

Maybe this path is "valid" but it's not valid when trying to retrieve
the associated icon from the .exe like this :

//...
SHFILEINFO shinfo = new SHFILEINFO();
hImgSmall = SHGetFileInfo(theprocess.MainModule.FileName, 0, ref
shinfo,(uint)Marshal.SizeOf(shinfo), SHGFI_ICON |SHGFI_SMALLICON);
//...

How can i convert this path to a "normal" valid path usable for other
function like SHGetFileInfo function ???
Any other way to get the path without the \\??\ prefix ??

Thanks!

Finally found a solution :
Remove the first 4 characters to remove the \??\
GetLongPathName api

Not sure if it's the best solution, but look like a lot of process
viewer tool use this kind of ugly direct manipulation with the path.
