单击按钮后如何显示.txt

Question

I asked this question a minute ago and was not specific enough so let me try again.

I am trying to generate a report of inventory information that is already made and have it update from the user input into text boxes on the form and then have a button to make the .txt file of the report show to the screen and have the updated information on it.

I have the GUI created and have the button created and the .txt file is created. I just need to know how to make it where I can click the button and have the .txt file appear to the screen.

Answer 1

    Using System.Diagnostics;
    ... 
    String filename = "C:\\....\data.txt"; \\ File Created With Information
    Process.Start(filename); \\ Will open file with default program

The above code can be used to open an external program to display your text file.

As usual I recommend using try/catch since you are dealing with external I/O (files).

Answer 2

You can just start the notepad process with your *.txt file as the argument and start the process can't you?

• Assign a click event to your button (in your class constructor for instance):

   button.Click += new EventHandler(button_Click); 

• In the event, start notepad.exe in a new process:

   void button_Click(Object sender, EventArgs e) { ProcessStartInfo startInfo = new ProcessStartInfo(); startInfo.FileName = "notepad.exe"; startInfo.Arguments = "C:\\Path\\To\\My\\file.txt"; Process.Start(startInfo); }
