Netspider Mitglied 10:40:00 14.11.2002 Titel:

Hallo,

ich bins mal wieder,
wie kann ich eine messagebox mit eingabefeld machen, die eine INT-zahl speichert???
Ist das eingegebene dann gleich 'ne zahl oder wird dass als string angesehen (oder char?) ??

edit: Titel geändert.

woher soll einer wissen, was fuer eine box du nimmst? ab nach mfc oder winapi oder so.

sag nicht so, das hört sich an als ob der da noch mal posten soll, wir verschieben lieber die Threads!

@Netspider in welches Forum soll der Thread verschoben werden?
Wohin mit meiner Frage?

LLLLLLLLLLLLLLLLLOOOOOOOOOOOOOOOOOOOLLLLLLLLLLLLLLLLL

.

wuerde es dir was ausmachen zu sagen
-mit welcher klassenbibliothek
-unter welchem betriebssystem
du das programmieren willst?

Netspider Mitglied 18:19:00 14.11.2002 Titel:

öööh, windows, VC++
ich dachte es gibt einen einfachen befehl mit dem man eine eingabe
des benutzers machen kann, muss das verschoben werden?????
ich verstehe nicht wieso das nicht hier reinpassen soll!

erst schreibe ich einen beitrag in das MFC forum und der wird sofort von euch gesperrt *grrr*
dann schreib ich hier rein und ihr meckert wieder !!!!!

[edit]hier ist mal ein beispiel, wie es aussehen soll,
für die, die noch nicht wissen, was ich meine.
einfach den link in ein browserfenster kopieren und starten
[java]
javascript:window.prompt('Testbox','test')[/code]

PeterTheMaster Mitglied 19:03:00 14.11.2002 Titel:

sowas ist mit standard c++ definitiv nicht zu erreichen. wenn es dir nur auf die eingabe, nicht das fensterchen ankommt, dann kannst dus ueber die konsole machen.
lies mal was ueber cin und cout.

Netspider Mitglied 19:07:00 14.11.2002 Titel:

naja, ich wusel so ein bisschen in Opengl rum und wollte aber vom user noch eine zahl abfragen, bevor das programm richtig startet, also mit windows und VC++, OpenGL und wenig ahnung ;-)

aber ein NIMM-Spiel habe icch schon hinbekommen *g*
- 21 streichhölzer am anfang, man nimmt immer 1-3, dann comp, wer das letzt zieht hat verloren *bg* -

Ich verscheibe den Thread ins WinAPI Forum.

Da musst du dir wohl oder übel einen eigenen Dialog basteln.

WebFritzi Mitglied 08:21:00 15.11.2002 Titel:

...oder WebFritzi arbeiten lassen.

Ich habe jetzt die ganze Nacht durchgearbeitet, um diesen dummen Dialog zu basteln (ohne Resource). Dabei ist folgende cpp-Datei herausgekommen ([edit]überarbeitete Version[/edit]):

Dann kannst du eine solche InputBox wie folgt aufrufen:

C/C++ Code:
1 2 3 4 5 6 7 8 9	1 2 3 4 5 6 7 8 9	char buffer[256]; int ret = InputBox(hwnd, "Eingabe in diesem Feld:", "Titel", buffer, 256); if(ret == IDOK) MessageBox(hwnd, buffer, "Die Eingabe war:", MB_OK \| MB_ICONINFORMATION); else if(ret == IDCANCEL) MessageBox(hwnd, "Es wurde \"Abbrechen\" gewählt", "INFO", MB_OK \| MB_ICONINFORMATION); else if(ret == 0) MessageBox(hwnd, "Ein Fehler ist aufgetreten", "INFO", MB_OK \| MB_ICONERROR);

Ich habe jetzt rund 48 Stunden dafür gebraucht. Dabei war Knobeln an der Tagesordnung, denn die MS-Dokumentation zu DialogBoxIndirect() ist sehr schlecht und fehlerhaft in mehreren Punkten. Im Netz ist auch nicht das Wahre zu finden. Aber jetzt steht das ganze hoffentlich (ohne Fehler), und man kann nicht nur InputBoxes damit erstellen, sondern Dialoge jeglicher Art. Dazu schaue man sich die Funktion InputBox() an. Diese nutzt wiederum die Funktionen InitDialog() und CreateDlgControl(), mit denen man seinen Dialog erstellen kann wie auch in einem Resourcen-Script. Viel Spaß damit.
