frage zu..doppeltes öffnen eines programmes vermeiden aus faq

[Surfman]

ja!!
ich will einfach C:\Programm.exe eingeben...dann soll er schaun ob der process schon läuft...kannst ja mir bissi helfen..;-)

ich versteh da mit der msdn nicht so viel...erklärungen sind auch keine dabei;-(

was machen die da mit....Process32First
hat jemand da eine example vielleicht wo man das besser sieht???
wär fein...

//   604 = No permission to terminate process
//   605 = Unable to load PSAPI.DLL
//   602 = Unable to terminate process for some other reason
//   606 = Unable to identify system type
//   607 = Unsupported OS
//   632 = Invalid process name
//   700 = Unable to get procedure address from PSAPI.DLL

jetzt muss ich halt das mittn terminate raus tun??? was meinst du soll ich das auf meine vorstellungen anpassen, so viel is ja net zu ändern??

cu surf.

[flenders]

Also ich weiß nicht, ob das nicht auch einfacher geht - bei mir klappt das nämlich mit FindWindow wunderbar:

if(FindWindow(NULL,"123456789") == NULL) MessageBox(NULL,"ICQ is not running","",0);

Für 123456789 musst du eben noch deine ICQ-Nummer eintragen! Teste mal, ob das so bei dir nicht auch klappt
Ansonsten kannst du ja mal mit Winspector ein wenig rumschnüffeln

[Surfman]

das sollte ja nicht nur für icq gehn*gg*

ich will ja auch schaun ob zb.: microsoft messanger.exe gestartet wurde...da werd ich lieber den code umbauen da obn oder was meinst??

ich würd mal sagn das soll in die faq *fg*

Ich würde sagen das darf auf keinen Fall in die FAQ, es läuft ja nicht mal durch nen Compiler, ohne das der (zu Recht) Fehler ausgibt...

Außerdem ist es für das simple Auffinden von laufenden Programmen ein mordsmäßiger Overhead, mit 'nem Viertel der Codezeilen geht es auch, Funktionen hast Du genug genannt bekommen hier im Thread...

hi!! ich werds heute noch für visual c++ optimieren!!

Das hat überhaupt nichts mit Optimierung für einen speziellen Compiler zu tun! Der Auszug, den Hepi zitiert hat ist schlichtweg falsch und wird von deinem Compiler mit Sicherheit auch nicht akzeptiert
So langsam habe ich irgendwei das Gefühl, du willst uns hier nur veralbern (um mich noch einigermaßen gepflegt auszudrücken )

mfg surf.

Wenn ich mir deine Quelltexte hier so ansehe, dann zucke ich irgendwie zusammen, wenn ich auch nur dran denke, das Du nun auch noch etwas für einen bestimmten Compiler "optimieren" willst...

Geh mal folgende Schritte systematisch durch:

1.) C bzw. C++ richtig lernen. Ich sehe da gravierende Grundlagenmängel!
2.) Kauf Dir "Windows Programmierung, 5. Auflage" von Charles Petzold
3.) Lies es durch!
4.) Schreibe erste, kleine Programme mit der WinAPI.
5.) Kauf Dir "Microsoft Windows Programmierung für Experten" von Jeffrey Richter
6.) Lies es ebenfalls durch, schlag zur Not im Petzold nach, falls Dir Grundlagen entfallen sind...
7.) Sieh Dir deinen obigen Quelltext an, vielleicht kannst Du mittlerweile auch drüber lachen...
