Error handling

[abdul]

I am using "ShellExecute" to open a file but I want to show an error message whenever the path or file is invalid or some other error occurs. How do I do that?

I have tried the following line of code but even if the specific path is valid, it still shows the error message:

if(ShellExecute(hwnd, "open",combotext,NULL,NULL, SW_NORMAL)==(HINSTANCE)ERROR_FILE_NOT_FOUND || (HINSTANCE)ERROR_PATH_NOT_FOUND || (HINSTANCE)ERROR_PATH_NOT_FOUND)
			   {
				   MessageBox(hwnd, "The specified file name or path was not found, or there is not enough memory to run this program. Please try again"
					   , "Error!!", MB_OK | MB_ICONERROR);
			   }

When I type "C:\" as the path, it opened The contents of C: but still showed me the message box. How do you fix that?

Try this:

HINSTANCE tempRes = ShellExecute(hwnd, "open",combotext,NULL,NULL, SW_NORMAL);

if ((long)tempRes <= 32) // Validate file
{
    // Error!!!
    MessageBox(hwnd, "An error occured while trying to access this file.", "Error", MB_OK | MB_ICONERROR);
}
