TCHAR* argv[ ]

[baerten]

Hello, i need to call wmain(int argc,TCHAR* argv[],TCHAR* envp[]) but how to create the TCHAR* argv[] ? it's possible to get different strings of argv via argv[0] ... [1] ... [2] The number of elements is stored in argc but which lenght has a TCHAR String ? I need the lenght to set the size of my malloc Big thanks for help :)

i didn't get your question. Do you know what is TCHAR ? it is just a tyepedef . If ur applicaiton is unicode TCHAR is wchar_t otherwise it is char.

If u can Dream... U can do it

you don't call main() or winmain() - or whatever the entry point is called - yourself. the system does it when you launch the application. a TCHAR is a char or a wchar_t, depending if the UNICODE (and _UNICODE) macro has been defined. to pass parameters to you main function, add command line parameters, and they will end as strings in the argv array

yup, :doh: i'm stupid, i found the answer it works via char** than allocate different char* to the pointers :zzz: I think i must stop to take drugs X| (Joke)

I call the DOS Main from out my MFC Application. The DOS Prog should run hidden(no visualization) in a thread (not process) but thanks nevertheless for your answer

U should read some books which discuss about Windows Internal viz Programming Applications for Microsoft Windows by Jeff Richter,it has mentioned who calls winmain or main:-O

never say die

I make a AllocConsole in a Thread, then i redirect the STD_OUTPUT_HANDLE of the hidden console to stdout then i start simply _tmain(...) In my MFC applic i can read the output with the function "ReadConsoleOutput" and it works, i get the characters in a buffer of CHAR_INFO

char ** args; args = (char**) malloc ( 2*sizeof(char*)); args[0] = (char*)malloc(50*sizeof(char)); args[1] = (char*)malloc(50*sizeof(char)); strcpy(args[0],"C:\\....."); strcpy(args[1],"\restart"); _tmain(2,args,0);

[toxcct]

is your program calling its own _tmain() recursively ? :wtf:

Nope, the MFC Applic calls the _tmain of the DOS-Project I call the _tmain in a thread, which was created by clicking on a button
