Simple/strange problem changing the text value of a text box

[dsm1995gst]

I've got a button_click function that calls a Powershell script and outputs the results into a text box. This sometimes take a few seconds, so I wanted to first change the .text of the textbox (called Results) to "Please wait... searching remote PC" so the user knows the program is actually doing something.

Results.Text = "Please wait... searching remote PC"
Results.Text = RunScript(LoadScript(fullPCinfoScript))

However, the text will not change. It basically waits to change the text of the text box until the Powershell script is finished, and by that point it is obviously too late. I also tested by creating a label and making the label say "Please wait... searching remote PC," but it does not change the text value of the label until the Powershell function is finished.

Label1.Text = "Please wait... searching remote PC"
Results.Text = RunScript(LoadScript(fullPCinfoScript))

If I test it by displaying a messagebox that says "Please wait... searching remote PC," the message box appears immediately.

MessageBox.Show("Please wait... searching remote PC")
Results.Text = RunScript(LoadScript(fullPCinfoScript))

Any ideas?

Try refreshing the control
Control.Refresh Method (System.Windows.Forms)

Results.Text = "Please wait...Searching remote PC"
Results.Refresh()
Results.Text = RunScript(LoadScript(fullPCinfoScript))

Or the Application.DoEvents() Method (System.Windows.Forms)

Results.Text = "Please wait...Searching remote PC"
Application.DoEvents()
Results.Text = RunScript(LoadScript(fullPCinfoScript))
