The information in this article applies to:
- Standard and Professional Editions of Microsoft Visual Basic for
Windows, versions 2.0 and 3.0
SYMPTOMS
If you set the ScaleHeight or ScaleWidth property of a container to a
negative value, the Height or Width property of all child controls are
saved incorrectly if the form is saved in ASCII format. When you re-load a
form or its project that was previously saved in ASCII format, it may look
like controls on the container have been removed. Actually, the child
controls still exist, but their Height and Width properties were saved
incorrectly, which results in significantly smaller controls.
WORKAROUND
To work around the problem:
- Resize the controls to their original size by using the mouse. You must
use the mouse; you cannot resize the controls by changing the Height and
Width properties in the Property window. Click the lower right-hand
corner of the control and drag it down or to the right to make the
control taller or wider, respectively.
- Save the form in binary format. From the File menu, choose Save Project
(ALT, F, V) and clear the Save as Text check box option.
STATUS
Microsoft has confirmed this to be a bug in both the Standard and
Professional Editions of Microsoft Visual Basic versions 2.0 and 3.0
for Windows. This problem has been corrected in Visual Basic version 4.0.
MORE INFORMATION
Steps to Reproduce Problem
- Run Visual Basic, or from the File menu, choose New Project (ALT, F, N)
if Visual Basic is already running. Form1 is created by default.
- From the Properties window, set the following properties of Form1:
ScaleMode: 0 (User)
ScaleHeight: -100
ScaleWidth: -150
ScaleTop: -100 Sets upper left hand corner coordinates
ScaleLeft: -150 of Form1 to (-150,-100)
- Add a command button (Command1) to Form1.
- From the Properties window, set the properties of the Command1 button as
follows to place the command button in the middle of the form.
Top: -150
Left: -200
- From the File menu, choose Save Project (ALT, F, V). Select the Save as
Text option and save the form using the default name of Form1. Save the
project (Project1) using the default name.
- From the File menu, choose Open Project (ALT, F, O). In the Files box,
select PROJECT1.MAK.
- From the Window menu, choose Project (ALT, W, R). Using the mouse, click
View Form in the Project window. Form1 displays, and you can see that
the Command1 button is significantly smaller, making it difficult to
pinpoint where it is.
- Using the mouse, click Form1 to change the focus to Form1.
- Press the Tab key to move the focus to the command button. Now Command1
becomes visible and the Properties window shows its properties.
You can resize or move the command button by using the mouse. However, if
you attempt to set the Height property of Command1 to a positive value,
Visual Basic incorrectly changes the property to its minimum value. The
minimum value for the Height property is based on the FontName and FontSize
properties.
