Question

I have this function which should run a shell command.
This is how I call this:

RunCommand("C:\\source\\in\\DSC00749.jpg -gravity Center -crop 100x100+0+0 -write C:\\source\\out\\DSC00749.jpg");

private static string RunCommand(string cmd)
    {
        const int ERROR_FILE_NOT_FOUND = 2;
        const int ERROR_ACCESS_DENIED = 5;

        string strErrMsg = "OK";

        try
        {
            ProcessStartInfo procInfo = new ProcessStartInfo("convert.exe");

            procInfo.CreateNoWindow = true;
            procInfo.UseShellExecute = true;

            procInfo.Arguments = cmd;
            Process.Start(procInfo);
        }
        catch (Win32Exception e)
        {
            if (e.NativeErrorCode == ERROR_FILE_NOT_FOUND)
            {
                strErrMsg = "File not found exception";
            }
            else if (e.NativeErrorCode == ERROR_ACCESS_DENIED)
            {
                strErrMsg = "Access Denied Exception";
            }
        }

        return strErrMsg;
    }

If I run this in command shell it works:

convert.exe C:\\source\\in\DSC00749.jpg -gravity Center -crop 100x100+0+0-write C:\\source\\out\\DSC00749.jpg

If I run in debug more or directly run it, it just doesn’t create the images.

What is wrong with my code? Am I doing it the right way?

Answer 1

Do you have full path to the convert.exe?

Try that and see if it works since you are not getting any exception.
