void FileOperation::fileRead(char cName[100] , char cSvnPath[100] , char cPass[100])
{
//char cName1[100];
//char cSvnPath1[100];
//char cPassword1[100];
FILE *fp;
fp = fopen("config.txt","r");
fgets(cName , 100, fp);
fgets(cSvnPath ,100 , fp);
fgets(cPass ,100 ,fp);
fclose(fp);
}

Now use the arguments in your main file

You just pass the arguments you want to your function. Calling a function and passing parameters is basics C++ so I really suggest you read some book before going on with classes otherwise you'll get totally lost.

oh my god !!! OMG | :OMG:

you know what ?
stop this immediately, go to a book shop, find Kernigan & Ritchie's Book about the C language, and read (i mean, read and LEARN) !!!

then you'll find all this becoming very easy

hey, it's not to annoy you if we suggest you to read books... it's for your own efficiency dude !

it's as if you drive a car without a license... how can you drive on a highway then if you don't learn driving first ? D'Oh! | :doh:

oh and By the way, if we "never answered properly" as you say, it's because you never ask properly ! Suspicious | :suss:

and at last, "u", "y" and "r" are letters; "you", "why" and "are" are the words to use if you want anybody to understand you. you're not an a chat room, and people around here are from all over the world. be compliant with the policies, and everything will be fine. if you don't want to comply, i'll stick on your ass to warn you as you already started to know me for this Poke tongue | ;-P

well, don't get me wrong.

i'm not paid to answer on this board. all i do is because i want to and i love it.

but i'm still thinking you have some lack of knowledge that you should fix fastly. calling a finction is part of the basics of the C/C++ (and any programming - in general...) languages. if you can't figure out how to call one, then you should start from the beginning.

i'm not obliged to do so, and know that i do my best anyway. but sometimes, i really don't understand the question, so how to help then ?
and if i was obliged to help, then the one who's asking should be obliged to ask with all the useful informations we must have to answer well in a one step. Is that Wrong ?

i hope you understood me and will make efforts in the future. for my part, i have nothing against you. just against your questions Wink | ;)

Dont Mind...

But as Sunit and Tox says you must read some c++ books for your further knowledge.

Since you're obviously using C++ you should use it correctly. Don't pass crap like char cName[100] as arguments in functions or as variables. Use the STL's std::string class for representing a string.

Thus you would rewrite the above as

void FileOperation::fileRead( const std::string& cName, const std::string& cSvnPath, const std::string& cPass )

second problem - you have variables defined within the local scope of your function with the same name as the arguments you've defined in your function. That could be problematic.

You should go out and get a good book on C++ first and get comfortable with the basics.

TCHAR* argv[ ]

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 Smile | :)

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

baerten8-Aug-07 23:42

8-Aug-07 23:42

yup,

i'm stupid, i found the answer

it works via char** than allocate different char* to the pointers Sleepy | :zzz:

I think i must stop to take drugs Dead | X|

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

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

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);

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