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:

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

While filling you can use clipping functions like SelectClipRgn etc.
and then u try painting with any gdi functions like (fillrgn etc)

If u can Dream... U can do it

Drawing the larger circle first and then the smaller one on top of it with background Color is not what your tutor wants you to do, I guess?

Hi,
I develop many direct show filters . I want to develope a filter
that takes many input (video , text , image ) and mix them .

Trioum

jk chan8-Aug-07 22:57

8-Aug-07 22:57

which is the video format ur using ? , and what will be the output pin format of ur filter ? i guess you may have many input pins and 1 output pin .

If u can Dream... U can do it

trioum8-Aug-07 23:22

trioum

8-Aug-07 23:22

yes
I am using many inputpins one output pin . i take input from
many live capture devices . bitmap text any one

Trioum

jk chan8-Aug-07 23:51

8-Aug-07 23:51

U havn;t told me the videformat.. anyway suppose ur input pin gets imag data (bmp), i think u can use GDI functions like bitblt for adding image or text to ur source image. then copy this bmp data to ur output imediasample . it might work

If u can Dream... U can do it
