Question

I am having problems when executing an event in C# using Process.Start. The statement below only outputs half of the command:

private void AddTask_Click(object sender, EventArgs e)
{
    Process.Start("schtasks.exe", string.Format(@"/Create /SC DAILY /TN", "\"" + textBox1.Text + "\"", string.Format(@"/TR C:\Program Files\test\scanner.exe C:\", "\"" + textBox1.Text + "\"")));
}

For some reason it cuts of at “/TN” e.g.

“C:\Windows\System32\schtasks.exe” /Create /SC DAILY /TN

Answer 1

For some reason it cuts of at “/TN”

Correct. In

 string.Format(@"/Create /SC DAILY /TN", "other strings");

The first string is seen as the format string, the rest are arguments, unused in this case.
Without {0} place holders you don’t need String.Format(), simply use

 Process.Start("schtasks.exe", @"/Create /SC DAILY /TN" + "\"" + ...

That doesn’t exclude the possibility of a syntax error in your commandline arguments.

Change it to :

string args =  @"/Create /SC DAILY /TN" + "\"" + ...
Process.Start("schtasks.exe", args);

And then you can inspect args in the debugger and maybe post here.
