User-Defined Types:

None.

Notes:

The last 4 overrides are probably more useful than the first. They can be used without any casting.

if the function failes, you can call Marshal.GetLastWin32Error() to get the error code, and send it to the Win32Exception constructor to get the message.

Tips & Tricks:

Please add some!

Sample Code:

this code finds a resource in another executable, loads it to memory, and returns a pointer to it.

    private IntPtr FindLoadnLock(IntPtr hExe, String fileName, String fileType) {
      IntPtr hResource;  //handle to resource
      IntPtr pResource;  //pointer to resource in memory
      hResource = FindResource(hExe, fileName, fileType);
      if (hResource.ToInt32() == 0) {
    throw new Win32Exception(Marshal.GetLastWin32Error());
      }
      hResource = LoadResource(hExe, hResource);
      if (hResource.ToInt32() == 0) {
    throw new Win32Exception(Marshal.GetLastWin32Error());
      }
      pResource = LockResource(hResource);
      if (pResource.ToInt32() == 0) {
    throw new Win32Exception(Marshal.GetLastWin32Error());
      }
      return pResource;
    }
