XL: Visual Basic Code to Resize an Application Window

• Microsoft Excel for Windows, versions 5.0, 5.0c
• Microsoft Excel for Windows NT, version 5.0

SUMMARY

In Microsoft Windows, you cannot resize a window if it is already maximized or minimized (for example, if the Microsoft Excel window is maximized or minimized, you cannot choose the Size command from the Control menu to change the size of the window).

However, you can resize another application's window from a Visual Basic, Applications Edition, macro that contains at least two API (Application Programming Interface) calls. For an example of how to do this, see the sample macro code below.
