Article ID: 150229
Article Last Modified on 1/9/2003
APPLIES TO
- Microsoft Visual Basic 4.0 Professional Edition
- Microsoft Visual Basic 4.0 16-bit Enterprise Edition
This article was previously published under Q150229
SYMPTOMS
If the Clip property of the Grid control is set equal to the Text property of an empty Text box, a General Protection Fault occurs.
RESOLUTION
The Clip property can be explicitly set to an empty string. If the Text box is empty, set the Clip property of the Grid control to an empty string. If the Text box is not empty, set the Clip property to the Text property. For example, instead of:
Grid1.Clip = Text1.Text
This problem can be avoided by using:
If Text1.Text = "" Then
Grid1.Clip = ""
Else
Grid1.Clip = Text1.Text
EndIf
STATUS
Microsoft has confirmed this to be an issue in the Microsoft products listed at the beginning of this article.
MORE INFORMATION
Steps to Reproduce Problem
- Start a new project in Visual Basic. Form1 is created by default.
- Place a Grid Control on Form1.
- Place a Command button and a Text box on Form1.
- Click the Property window for the Text box and delete the Text property (delete "Text1").
In the Click event of the Command button, place the following code:
Private Sub Command1_Click() Grid1.Clip = Text1.Text End Sub- Run the project by pressing F5. When running this code under Windows NT 3.51, the following error message displays:
To work around this problem, change the code in the Click event of the button to:
Private Sub Command1_Click()
If Text1.Text = "" Then
Grid1.Clip = ""
Else
Grid1.Clip = Text1.Text
EndIf
End Sub
