i've also behaviored like below :
_buffer[0] = _buffer[0] + 1;
but the problem is there.

you just have to change the "access database" to "excel database" sql connection string.

have a good time dear friend
You know that the excel is a kind of database and you should connect and work with it like a database.
This tutorial can helps you to do this :

hi dear friend
At first you have to download the Android-NDK and then install that.
After that you should set the NDK installation path to the "Environment Variables"

Dear Afzaal
Thanks for your response
Would you more explain for me?
What's the path that i should go or learn and also the language programming?

mr ridoy
is there another way to do this?
what do you think about it?
a way that a person in home can access to it.

ohi really thanks to guide me

thanks dear ridoy to spend your time to ans my question

in that article he said that "it's not possible..."
but i have question and that it we have and we see many application-android that change the voice during live call.
how do they do?
i think at first they get the mic buffer
second change the buffer
and finally send the buffer through call
am i right?

thanks again

thanks dear pal for your solution

Well
I want to write an application like winrar but at here there a different, we put some files in a package like .rar and then open this archive by winrar, now we double click on a file, what happens? A file will extracted to hard disk then runs.
i need to do this but i don't want create any file ondisk(cause of security).

wow ! . your explanations are complete.
i really thank you for helping and the time you have spent.

Thanks dear Jochen.
i read your post and got useful information about IPC.
i think i use the send/get message for my project.

but can you tell me how can i share a part (address) of RAM between two applications?

dear friend
i also use the "this" but when the application(VB.net) will be opened, error will happen.

oh right!
i wrote it and "inside" has no type.
but below error accured :

error C2582: 'operator =' function is unavailable in 'ClassLibrary2::class1::class2'

thanks dear friend for your solution and your attention.

but i've a question that is :
what type do i declare the inside?

i also worked on "CLR DLL" (ClassLibrary). in this status, i could access the sub class of dll form vb.bet but there was a problem :

for example :
we have below code in CLR :

namespace mydll{

public ref class class1{

public:

ref class class2{
public:

int x;
}

};

};



then in the vb.net to access the "var x" we have to write this code:
#1

dim a as new mydll.class1.class2
a.x=10



while we need to write code like :

#2

dim a as new mydll.class1
a.class2.x=10

when i used code#2,in the vb.net occur an error.



in fact i need the suitable hierachy of class and it's sub's without extra definition.
i also need to access and create the array of c++'s class's and strings in vb.net.

like :

dim a as new mydll.class1
a.class2.x=4
...

thanks dear jochen

i removed the part of #ifdef _WINDOWS_ ....

but the error is still there.
all right
i'll talk to you there

i undefining _WINDOWS_ because pre error was the windows.h is already included.
i searched about it and i found this code to prevent definition again.

dear friend
thanks for your ans
but you saw my .h code
i've never included the windows.h and winsock.h

in fact my project isn't MFC project.
i'm using the CWnd and... in console and work with them.

can you help me more?

dear vengala
my os is windows7 and i also run the visual studio as "run as admin" but didn't work.
please help me

i did it.
i change the security of this folder for all user and full control.
but didn't solved.

look dear friend
designing and building the compiler for a language programming is to difficult.
that needs the compiler writing science at first, then needs high skill to code that, even convert the codes to machine language.you have to work with strings and it's category: tokens and several concepts.
the DFA and NFA language and ... theories...

but you can design the interpreter for your language.
it's easy.
interpreter is like the compiler,but in the interpreter the codes will not convert and translate to the machine language. it's like the run time code like javascript.
it means you make the program that read every code and does it's action for each statement.
to design it you just should use "if" condition for each code.

hello pal


at first you should determine that what Database Software and What Application Programming Language do you want to use?

step by step
if you want do this with Visual C++ tell me what do you want untill i send to you.

i got the path of the work and it's too soon for me.

thanks alot

I'm working on a project that i have to do this with code(manually).
can you give any reference?

about the "OnPaint" yes, but about the "Created" variable
it is inner variable:
class Theme:Public CWnd{
public:
bool Created;
};

and in the another Derived varibale form "Theme" it's different from pre "Created" in First Class, doesn't it?

i update my question.
please see above text of question.
thanks again

can you tell me what the BM_SETIMAGE is?
event or function?

thanks for your answers
but i want to compile my project that will be run in windows xp x86.
i work with windows7 x64.
can you help me?
thanks in advance

dear friend
thanks for your answer
but i want to know what code is more faster from "GetPixel()" and "GetRValue()" functions to get color from image.

Dear friend
you want do it in C++ Console or Visaul C++?

Dear friend
this is not a solution.It's a comment.
The solution solves a problem.

Dear friend
to do this, there's many ways.
you should encrypt the file by your specific structure.
you just design the structure and formula of your encryption function.
for expample , you increase plus every characters with constant number. then the file won't able to execute.

may be you have written a code that related to "MouseMove()" on the combo that happen so.
You should see the code exactly.

When i use The PostQuitMessage, this works.even WM_CLOSE and WM_DESTROY.
may be the your windows is has wrong.

dear friend at first you should know the structure of 3dmax file to convert it to the txt file.
like you see,first there is the object list and between of them is their coordinates of vertexes.
after that you have to write a interpreter program that convert the source structure file to destination file.
it's long.

Hi dear friend
even you use open cv, you should to know the algorithms for doing this.
the open cv is just a code that help you do quickly process from Graphic card like open gl.
am i correct?

Did you search in MSDN?
That's the reference document of visual studio.

Can you explain for me that what's the add-in?

the file breakpoint file has true value.
i don't know what's wrong.

yeah i'm sure.
i cleaned solution and rebuilt it several.
but the program works but without breakpoint.
thanks for you answer dear.

thanks man.thanks
