textbox value doen't change

[1974maiden]

Sorry,
If this question is ridiously easy ...

' If I click on a button (event) then I can change my textbox value

Private Sub btnClosePort_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnClosePort.Click
txtSend.Text = "Text value Changed"
End Sub

'But how can I change the data in a textbox for non-events

Public Sub senddata(ByVal s As String)
'doing something with s
'doing something
txtSend.Text = "Value not changed" 'DOES NOT WORK
End Sub


Thanks

Everything is event driven. Some event has to happen to change the text. Like:

Private Sub btnClosePort_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnClosePort.Click
      senddata("Close Port Clicked")
End Sub

Public Sub senddata(ByVal s As String)
        'doing something with s
        'doing something
        txtSend.Text = s
End Sub

I understand but it does not overwrite the orignal text in the textbox.

You may want to check if the textbox has READONLY property set to true, in which case it will not be overwritten.

If setting txtSend.Text = s does not change the value of the text box that means either s contains the same value as txtSend.Text OR the text box you are looking at is not txtSend.

The read only flag will only prevent users from being able to type in the text box, you can still set the text value from code.

...or the textbox needs to be redrawn.

After changing its text, do an Application.DoEvents.

txtSend.Text = s
Application.DoEvents

... or txtSend.Refresh


Hope this helps.
