Flackernde Buttons???

Hallo.
Warum flackern/verschwinden die Buttons beim Button_Click-Ereignis?

bitte beim nächsten mal code tags vewenden (denn dann mach ich es nicht für dich :p )

Wie wende ich "System.Brain" an?

denke mal scharf nach
mal im ernst: minimier doch deinen code erstmal auf das nötigste, nimm alle panels und was da sonst noch rumfliegt raus und dann wirst du vielleicht schon den fehler selbst rausfinden.

Wird wohl an der Technik liegen wie Windows Fenster zeichnet
Du kannst (zumindest bei .net 2.0) Double-Buffering für das Fenster aktivieren und hoffen dass die Software ab WinXP eingesetzt wird - vorher kennt Windows kein DoubleBuffering.Wenn die Größe eines Panels geändert wird, zeichnet Windows erst den Hintergrund des Panels neu, dann das Panel selbst, dann den Hintergrund eines Buttons der da drauf-liegt und dann den Button an sich. Da das zeichnen allerdings nicht in 0 ms passiert und vor allem wenn das Panel animiert wird, kommt es dann zum Flackern.
Die WinAPI-Leute fuckeln dann immer mit nem Backbuffer rum. Quasi eine Bitmap im Arbeitsspeicher in der vorher alles reingezeichnet wird und wenn das Zeichnen fertig ist, wird der gesamte Backbuffer gezeichnet. Dadurch wird quasi alles im Hintergrund gezeichnet und dann mit einem Schlag das Ergebnis angezeigt.
Seit WinXP gibt es in der WinAPI ein Flag WS_EX_COMPOSITED, das DoubleBuffering für ein Fenster einschaltet. Das dürfte dem oben genannten im .net-Framework entsprechen.

Ich habe jetzt das
while(panContainer2.Height<=(x))
in
while(panContainer2.Height==(x))
geändert. Es flackert nicht mehr!
Aber: Das "AnimationRate" greift jetzt auch nicht mehr.
Und genau diesen Effekt brauche ich. ?

Servus,

abgesehen davon das ich das noch nie genutzt habe aber stimmt das wirklich? Dann würde ja folgendene Möglichkeit keinen Sinn machen
this.SetStyle(ControlStyles.DoubleBuffer, true);Echt eine dumme Frage von mir: Wenns doch nicht funzt, wofür sollte ich dann SetStyle verwenden? *nixrallt*

Hmm, probieren geht über studieren.
Rein-theoretisch kann erst Windows XP DoubleBuffering.
Zumindest steht da nen Windows XP davor:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/winui/windowsuserinterface/windowing/windows/windowreference/windowfunctions/createwindowex.aspMir scheint bisher das ganze Windows.Forms wieder nur ein WinAPI-Wrapper zu sein.
Beispielsweise kennt die ListView in der WinXP-Version noch das Feature "Groups", in Win2k gibt es das noch nicht.
Verwendet man nun die ListView des .net 2.0-Frameworks und benutzt da Groups, dann werden unter Win2k keine Groups angezeigt ;/
Oder hab ich etwas falsch gemacht ?Und ich dachte bisher die Controls im .net-Framework wären unabhängig von den bestehenden Controls der jeweiligen Windows-Version implementiert worden.
Andererseits steht hier:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemwindowsformscontrolstylesclasstopic.asp
nichts davon, dass das erst ab WinXP funktioniert.
(Oh, da steht das mit Flicker-Reduzieren nochmal etwas anders!!)Naja, hier habe ich gerade keine Win2k-Maschine zwecks testen
