Title Bar Flickering

[Tommy]

When going from one form to another the titlebar on my vb app flickers back
and forth from the underlying to the top form. It all happens in the
InitializeComponent() function of the new form.

If i step through my code it all happens only on that line. It's very slow
and very noticable. My forms have a quite a bit of code on them and a few do
some db access in the load.

To create the form and show it i simply use the following code:

Dim oFrm as New Form1
oFrm.ShowDialog

Thanks for any help.

This was a bug in the RTM release of .NETCF v1.0. Installing the latest
runtimes to your device (currently Service Pack 2 although SP3 is in Beta)
should sure this. You can download SP2 here:-

Does that go for vs.net 2003? Doesn't it have the cf framework 1.1?

Thanks,
Tommy

There is no CF 1.1

For CF version info please visit:

Is it possible to install ServicePack on an emulator? especially is it
possible to install it for keeps for an emulator.

You can install the X86 version in the download linked below to the
emulator - it will of course be lost if the emulator is hard-reset. Another
option (although not supported) is to overwrite the RTM versions of the cab
files within VS2003 with the updated SP2 versions so for example for the
Pocket PC 2002 emulator copy netcf.core.ppc3.x86.cab from the SP2
redistributable to
C:\Program Files\Microsoft Visual Studio .NET
2003\CompactFrameworkSDK\v1.0.5000\Windows CE\wce300\x86\

Then whenever Visual Studio deploys the framework to a freshly reset
emulator it will install the SP2 version.

Thank you, Peter!

It seems the sp2 fixed that problem and caused another.

I have a class containing some buttons to act as a mini tool bar that get's
instantiated in the load of some of my forms. When i click one of those
buttons and show a utility form with showdialog and close that dialog form
the underlying form is gone. I have to go to memory settings of the device
and select the form then click activate to see it again.

This didn't happen before the service pack.

I tried Bringtofront(), Focus() and Show() on that hidden form after closing
the dialog for to bring it back to the top but nothing seems to work.

Any experience with this problem anyone?

Thanks,
Tommy

BringToFront is sometimes not very effective, try SetForegroundWindow,
requires a bit of P/Invoke but much more reliable - a code sample here:-
