Probleme mit PostMessage(WM_KEYDOWN)

[Periander]

Hallo ich habe folgendes Problem:
Ich will ein Programm schreiben, dass die ausgewählte Taste einem beliebigen andern Programm simuliert. Dazu habe ich eine Combobox eingerichtet, in der man die Tasten wählen kann.
Dieses erkennt dann das Programm:

Delphi-Quellcode:

 ch := ar[i].var1;
     Case ch of

           0 :begin  c:=vk_F1; end;
           1 :begin  c:=vk_F2; end;
           2 :begin  c:=vk_F3; end;
           3 :begin  c:=vk_F4; end;
                    (...)
           26 :begin  c:=Ord('a'); end;
           27 :begin  c:=Ord('b'); end;
           28 :begin  c:=Ord('c'); end;
                    (...)

und soll diese dann simulieren:

Delphi-Quellcode:

       if ar[i].var1 < 26 then
       begin
       PostMessage(w,WM_KEYDOWN,c,1);
       pause(ar[i].zeit,i);
       PostMessage(w,WM_KEYUP,c,1);
       end;
       if ar[i].var1 > 25 then
       begin
       PostMessage(w,WM_KEYDOWN,c,0);
       pause(ar[i].zeit,i);
       PostMessage(w,WM_KEYUP,c,0);
       end;

Das klappt soweit mit allen "vk_" tasten auch wunderbar, allerdings funktioniert es mit den chars nicht! Ich habe schon soviel ausprobiert...

Ich hoffe ihr könnt mir weiterhelfen.

Hallo,

ich würde vermuten, Du musst Großbuchstaben senden (65 = A, 66 = B usw.). Ob ein Großbuchstabe oder ein Kleinbuchstabe gemeint ist, hängt ja vom Status der Shifttaste ab. Und die sendet ebenfalls ein KEYDOWN/KEYUP-Paar.

Danke für dir schnelle antwort.

du meinst, sowas hier: (ohne die Variable)

Delphi-Quellcode:

       begin
       PostMessage(w,WM_KEYDOWN,66,0);
       pause(ar[i].zeit,i);
       PostMessage(w,WM_KEYUP,66,0);
       end;

Das funktioniert nicht, oder wie genau meinst du das?
Verzeiht, wenn mir teilweise Grundkenntnisse fehlen.

[SirThornberry]

bei der Keymessage bekommst du (soweit ich mich erinnere) nicht das Zeischen sondern die Taste. Du musst zu der Taste also auch noch weitere Dinge mit schicken (Keydown, keydown-count etc.)

[Christian Seehase]

Moin Periander,

erst einmal herzlich willkommen hier in der Delphi-PRAXiS.

Bei WM_KEYDOWN kann der letzte Wert 0 sein, bei WM_KEYUP solltest Du aber mindestens $C0000000 für lParam angeben.
(siehe WM_KEYUP)

[Periander]

Hmm... leider hat nichts davon funktioniert.

Könntet ihr vielleicht einen Beispielcode posten, der mit der PostMessage einen Buchstaben schickt? Ich habe die Vorahnung, dass ich etwas ganz kleines falsch mache.

Danke

[SirThornberry]

für Buchstaben kannst du übrigens wm_char nehmen.

[Periander]

also folgendes funktioniert jetzt:

Delphi-Quellcode:

postmessage(form2.Efname.Handle, wm_char, ord('\'), 0);

will ich das zeichen aber an ein anderes fenster schicken, mit:

Delphi-Quellcode:

w := FindWindow(NIL,('Name des Fensters'));

sendmessage(w,wm_char,ord('\'),0);

geht es nichtmehr (auch nicht mit postmessage)

Ich denke das Sendmessage nicht die geeignete API dafür ist.
Versuchs mal mit SendKeys ;)

SendKeys('{ENTER}', True)
Simuliert den druck auf die Enter Taste und sendet sie an die andere anwendung

Alternativ ginge dies vielleicht auch noch.
SendMessageByNum(hWnd, WM_CHAR, 13, 0) 13 ist das ASC zeichen für ENTER.

Text wird so gesendet
SendMessageByString(hWnd, WM_SETTEXT, 0, '\')

was für "uses" brauche ich dafür?
Er erkennt diese art von API nicht.

gibts nicht die SNDKEY32.pas in Delphi?

ahh... das sieht schonmal ziemlich gut aus.
Werde damit erstmal noch ein bisschen rumprobieren.
Vielen dank für die schnelle Hilfe.

Zitat:

Zitat von Periander

also folgendes funktioniert jetzt:

Delphi-Quellcode:

postmessage(form2.Efname.Handle, wm_char, ord('\'), 0);

will ich das zeichen aber an ein anderes fenster schicken, mit:

Delphi-Quellcode:

w := FindWindow(NIL,('Name des Fensters'));

sendmessage(w,wm_char,ord('\'),0);

geht es nichtmehr (auch nicht mit postmessage)

Sendest du die Message an das Eingabecontrol oder an das Hauptfenster? Der Name des Fensters (Eingabecontrols) ändert sich ja sobald etwas eingegeben wurde.
Wenn man an Form2.handle etwas schickt wird ja auch nicht der Text ins Eingabecontrol geschrieben. Ich glaub du hast enfach das falsche handle.
