i have this code:
private void button1_Click(object sender, EventArgs e)
{
Process p = new Process();
p.StartInfo.FileName = \"C:/Users/Valy/Desktop/
I've searched on the internet for a solution at your problem and found this site: http://www.widecodes.com/0HzqUVPWUX/i-am-lauching-an-opengl-program-exe-file-from-visual-basic-but-the-texture-is-missing-what-is-wrong.html
In C# code it looks something like this:
string exepath = @"C:\Users\Valy\Desktop\3dcwrelease\3dcw.exe";
ProcessStartInfo psi = new ProcessStartInfo();
psi.FileName = exepath;
psi.WorkingDirectory = Path.GetDirectoryName(exepath);
Process.Start(psi);
