Fix your forms to paint borders correctly under Vista Aero

I've modified the code: instead of swapping the DoCreate and the BorderStyle, it now inserts the BorderStyle before the DoCreate. It might make a subtle difference, although I don't know of any cases where it would.

Calvin,

Your continued contributions to the VFP community are much appreciated. Keep up the great work!

Hi Calvin,

thank you very much for another insight into the inner workings of VFP. I'd like to add that your fix can be called from a project hook class' BeforeBuild event.

Unfortunately it's not as useful for a professional VFP user. Most of us are using Visual SourceSafe with VFP. So most forms are checked in at build time and thus are read only (removing the read only attribute is not really an option).

As the ProjectHook class has no BeforeCheckIn event I have no clue how to automate running your code before check in.

Any idea?

TIA,

Markus

Unfortunately this fix does not work - at least under VFP 8. Mostly (but not always) the borders are correctly painted on creation, but if a form is opened over the top, or the form moved over the edge of the screen and back, corruptions occur. The properties of one my forms that does not work (after Calvin's fix) are:

Height = 396

Width = 314

BorderStyle = 2

DoCreate = .T.

ShowTips = .T.

AutoCenter = .T.

Caption = "Letter Generator"

ControlBox = .F.

Closable = .F.

MaxButton = .F.

MinButton = .F.

WindowType = 1

Name = "LETTER"

I have tried moving other properties before the DoCreate, but without success. Interestingly, running as administrator does correct the problem.

Another workaround I have just tried is to set HalfHeightCaption = .T., which gives a Windows 2000 look, but does seem to avoid the corruptions.

A final problem affecting VFP applications is with fonts corrupting. I understand from Rick Strahl that this is due to the ClearType setting which is now default in Vista. Are there likely to be any solutions to this?

Dominic:

I tried creating a form with exactly the same properties as you specify in VFP8, and it repro’s the Aero problem as expected. I run the fix in my code above to put the BorderStyle before the DoCreate, and the problem goes away. Keep in mind that every time VFP rewrites the form from any modification, the fix above needs to be applied. If you can still repro the problem, can you provide the exact repro steps. Thanks

Markus:

Perhaps in your beforeBuild event you can run code that turns off the readonly attrib, applies the fix. The AfterBuild event can be used to clean up. You could even make/restore a backup copy in these events.

Calvin,

When the border/Titlebar is not shown, clicking outside the form and clicking back inside the form sometimes repaints it correctly with a Titlebar

Have taken out the 'DoCreate = .T.' line altogether. Some testing seems to confirm that this is another possibility

(1) Compile form does not put 'DoCreate = .T.'

(2) Editing a form does put the 'DoCreate = .T.' back

Any thoughts ?

How can I enabled the Aero Glass effect to a VFP program that's built as a SDI? In other words, this program uses the main VFP screen at runtime. VFP ignores the Aero Glass effect. Can it be enabled in this instance?

Windows Vista border issue and SP2

We've figured out the Vista border issue (we think). We couldn't reproduce it here, but Jim Slater noted

The Border problem exists also with Border Style = 3. I fix the program be amended and all was well.

Hi Calvin. I'm coming late to the party but have the same VFP form border issues and need some clarity. All of the forms in my app. were built using Vsual Fox Express and VFP9. All of the forms are VCXs. None are SCX. Nevertheless, in Aero, they all paint correctly at startup but any form movement (moving a form from one place to another on the screen) or calling another form corrupts their borders. The form's title bar disappears thereby losing its Min, Max and Close buttons.

I haven't tried your code because your message imples the VCX forms should behave correctly. What am I missing? Thanks.
