VB Graph Control: ThisPoint, ThisSet Reset to 1 at Run Time

• Microsoft Visual Basic Professional Edition for Windows, versions 2.0, 3.0
• Microsoft Professional Toolkit for Microsoft Visual Basic programming system for Windows, version 1.0

SUMMARY

The Graph version 1.2 custom control in the Professional Edition of Microsoft Visual Basic versions 2.0 or 3.0 for Windows, and in the Microsoft Professional Toolkit for Visual Basic version 1.0 for Windows, allows you to set the values of the ThisPoint and ThisSet properties at design time to aid in the development of your graphs. However, when you run the project, the Graph custom control resets the property values of ThisPoint and ThisSet to 1.

This behavior is a design feature of the Graph custom control to help avoid logic errors in your code. If your program requires ThisPoint and ThisSet to be a value other than 1 upon execution of the project, you will need to specifically set these property values in the program's code.

MORE INFORMATION

The example below demonstrates that ThisPoint and ThisSet are reset to 1 at run time.

Example

1. With Visual Basic for Windows running and Graph loaded, create a form (Form1).



2. On Form1 create a graph control (Graph1).



3. Change the following properties:

   
   Control           Property          Value
   -------           --------          -----
   Command1          Caption           Show values
   Graph1            Top               2000
   Graph1            NumSet            2
   Graph1            ThisPoint         2
   Graph1            ThisSet           2 




4. Add the following code to the Command1 button Click event:

   
   Sub Command1_Click ()
        Form1.Print "Graph1.ThisPoint = "; Graph1.ThisPoint
        Form1.Print "Graph1.ThisSet = "; Graph1.ThisSet
   End Sub 




5. Press the F5 key to run the program.
