FIX: Debugger Hangs Expanding TreeView in Debug Watch Window

MORE INFORMATION

Steps to Reproduce Problem

1. Create a Form and add a TreeView Control to it as following:
   • Choose OLE Container Control in the Form Controls toolbar and then click the Form.
   • When the Insert Object dialog comes up, select the Insert Control option and then select the TreeView Control from the Control Type list. Click OK to return to the Form Designer.
2. Add a Command button to the form with the following code in the Click event:

      USE HOME()+"samples\data\customer"
      SELECT customer
      oNodes = THISFORM.oleControl1.Nodes
      oNodes.CLEAR
      SCAN
         oNodes.ADD(,1,ALLTRIM(cust_id),ALLTRIM(company),0)
      ENDSCAN
   							

3. Run the Form. Click on the Command button to populate the TreeView object.
4. Open the debugger and enter the following in the Watch Window, and then press the Enter key:

      _SCREEN.ACTIVEFORM.OleControl1
   							

5. In the Watch window, expand the "SCREEN.ACTIVEFORM.OleControl1" watch expression.
6. Expand the Objects section of the TreeView OleControl.
7. Expand the Nodes section of the Objects section.

At this point, Visual FoxPro for Windows will freeze and you will not be able to perform any functions from within Visual FoxPro for Windows or the Debugger window.
