Last changed: odalet-77.136.18.190

.
Summary
Searches the current PATH for the specified file

C# Signature:

[DllImport("shlwapi.dll", SetLastError=true)]
[DllImport("shlwapi.dll", CharSet=CharSet.Auto, SetLastError=false)]
static extern bool PathFindOnPath([In, Out] StringBuilder pszFile, [In] String [] ppszOtherDirs);

VB Signature:

Declare Function PathFindOnPath Lib "shlwapi.dll" (TODO) As TODO

Notes:

Make sure pszFile has enough space for MAX_PATH characters.

ppszOtherDirs is a list of specific directories to search first. It can be null if you want to search only the PATH.

This function does not include the current dir or the application launch dir in its search.

Tips & Tricks:

None.

Sample Code:

int MAX_PATH=260;

StringBuilder sb = new System.Text.StringBuilder("LVComplianceRunner.dll", MAX_PATH);
bool found = PathFindOnPath(sb, new String [] {"c:\\test", "c:\\junk"} );
if (found)
{
    Console.WriteLine("File was found at: " + sb.ToString());
}
else
{
    Console.WriteLine("File was not found");
}

Alternative Managed API:

None that I could find.
