Problem mit WS_EX_COMPOSITED

Nestos

Schönen Abend alle.

Und hier gleich zu meinem Problem:

Ich habe ein Script geschrieben, was einen String in GDI+ darstellt. Mit dem Hotkey 1 soll man das Bild bewegen können. Das klappt ja auch soweit ganz gut. Nur flackert es dann halt total. Ich hab es dann mit VM_COMPOSITED versucht, was aber nur zufolge hatte, dass garnichtsmehr angezeigt wird.

Dein Problem mit dem geflackere kann ich nicht nachvollziehen, bei mir flackert nichts.
Welches Windows benutzt du? Hab es auf Vista getestet.

Probier mal das Script.

Edit: Der Titel deines Threads ist leicht verwirrend. Du solltest WS_EX_COMPOSITED verwenden und nicht WM_COMPOSITED.

Nestos

Danke für die schnelle Antwort.

Ich hab Win XP ServicePack 3.

Dein Script flackert genauso wie das meine.

SEuBo

Habe keine Ahnung von GDI+ aber ich bin gestern abend durch zufall hierdrauf gestoßen

Vielleicht hilft das weiter...

Ja Danke, das hat zwar nich mein Problem gelöst, aber hat in Erfahrung gebracht, dass Win XP anscheinend anders mit GDI+ arbeitet als Win Vista.

Jam00

Ich hab win7 und da Flackert es auch

Nestos

Das ist irgendwie komisch.

Kann mir denn jemand zeigen, wie das mit WS_EX_COMPOSITED funktionierd?

simon

Hab auch Vista und flackert nicht versuch mal

[autoit]

BitOR(-1,$WS_EX_COMPOSITED)

[/autoit]

Nestos

@simon: Jetzt wird zwar etwas angezeigt, aber das flackern ist immer noch da.

**Greenhorn**

Hi,

Windows XP hat ein Problem mit dem Fensterstil WS_EX_COMPOSITED.
In der Titelleiste, z.B., werden die Schaltflächen des Systemmenüs (minimieren, maximieren, schliessen) nicht mehr "gehighlighted".

EDIT:
Probiere doch einmal, ob das hier hilft...

[autoit]

GUIRegisterMsg ($WM_ERASEBKGND, "OnEraseBkGnd")

[/autoit][autoit][/autoit][autoit]

;...

[/autoit][autoit][/autoit][autoit]

Func OnEraseBkGnd ($hwnd, $message, $wParam, $lParam)

[/autoit][autoit][/autoit][autoit]

Return 1

[/autoit][autoit][/autoit][autoit]

EndFunc

[/autoit][autoit][/autoit][autoit][/autoit]

Danke.
Das funktioniert wunderbar.
