It is NOT an extension DLL, just a normal DLL. I see your point and will look into extension DLL or mangage the state in the callback.
I think were done here - many thanks

Cool. Try adding this to the top of the callback...
AFX_MANAGE_STATE(AfxGetAppModuleState());

Dear all;
I have finished building an MFC Application in Microsoft visual studio 2003. Now I would like to produce an executable application which can be used in any machine.
How do i do that? please post any articles or help guidelines.
I am thankful

I think you need to be more specific, "any machine" would include my refrigerator.

Oh sorry,
I meant any computer machine which has windows XP installed on it.

Deployment of MFC applications is documented on msdn so you can find everything you need there. Perhaps some searching like this[^] would help.

What does a "build" actually refer to?

I meant implementing or coding. The point i am trying to express if that i have tested the application within Microsoft visual studio 2003 and it works great. Now i would like to run the application outside the development environment.
I hope this is clear enough.

Oh! hmm, well haven't you ever opened your project folder? Have you seen these folders? "Debug" "Release" ? All the binaries you build will get created there. If your .exe doesn't have any dependency, you can take that .exe straight from the "release" folder and distribute. but it's not the usual case. Even if you do something with MFC, it will become mfc dlls dependant. (assuming you are linking dynamically). So use an installer like "Innosetup" (google for it). it's free and cool. You can deploy apps on the fly.

lol, indeed i have opened my project folder so many times. I have tried using the '.exe' file from the release folder but i encountered problems and thats why i posted this question. As you said it must have dependencies.
Ok, i will look for Innosetup and try it.
Thank you

Hello,
I am working for C project. The codebase exist since long time(more than 10 years).
We are using lots of structures with fixed array size. Like
struct tagMystruct
{
char name[256];
char disign[256];
.
.
}
Now new requirement came, I have to change fixed size arrays to dynamic arrays. I defined new array like
struct tagMystruct
{
char *name;
int nameLength;
char *disign;
int disgLength;
.
.
}
Is this correct approcach? In my existing code in lot many places we are using strcpy, strcat etc..
Now i have to check the buffer all the place before calling any function. It will take more time and regression? Can i know how can achive or any new ways?
Thanks and Regards,
Chandu

If the requirement is it must remain C code, then you have to do something like that you've exposed in your post.
However, if you can afford the C++ power then I strongly suggest to use STL's std::string instead of char * (at least toxcct will be happy  ).
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

As another wrote, think whether it can be a C++ project so, you can use classes. For instance you can use the std libs or the MFC (with CString). There are a lot of other classes here at CP.
Try to develop with structs, as
stringStruct
{
int l;
char *p;
}
If you cant use classes you should think about implementing often used operations in funktions.
SetString( stringStruct *p, "new string" )
{
//do stuff
}

Yes, you can do that since you mention that it is a "C" project, hence no C++ code. If you can build the project in C++, you can then use string objects (MFC's CString, STL's std::string) that will handle the memory allocations for you as well as supply methods for assignment, concatenation/appending, etc.
If you have to stick with the manually-managed buffers, be sure that when calling the string-related functions, you take care to use the n versions of the functions, like strncpy(...), so that you can help protect yourself from buffer overruns.
Peace!

There's one thing you shouldn't forget. that's to delete the "new"ly allocated buffers.
But,std::strings. Just awesome.

I am working on a project, where i have to catch event on Update of the particular control , message is already defined for it.
Between BEGIN_MESSAGE_MAP and END_MESSAGE_MAP i am putting
ON_MESSAGE (Messagename,UpdateFunction) statement with message and function name as a parameter.
i have written definition of UpdateFunction in the same class.
Problem  is while running and updating control UpdateFunction is not getting executed. 
is there anything i am missing for handling this ?

Do you SendMessage or PostMessage to the class that you defined message in it or the framework should do that for you?
Did you define a custom message or just redirect the same message?
Which message is it? What type of control? Is it a custom control for example?
Would you please provide some of your codes or at least more details.

yah its a custom control and message is also a custom one , redirecting to other message ... , i mean to say that its a custom table control when i update a cell value it should get to that method which i have specified in On_Message ...
I just wanted to ask that is there anything that we have to do while handling messages
1)Define entry in message map
2)provide declaration and definition of Method (which you want to execute on event of message)

If it's a CUSTOM message, then we shall follow the instruction:
1. Event handler MUST return LRESULT
2. Message variable should be defined in a right way, easiest: #define MyTestMessage WM_USER+1
3. Function declaration in the header file should should be written before DECLARE_MESSAGE_MAP() (e.g LRESULT OnSomething(WPARAM wParam, LPARAM lParam); )
4. In .cpp it should be declared in a MESSAGE_MAP block: (e.g.ON_MESSAGE(MyTestMessage, OnSomthing))
5. ALWAYS return 0 in the message handler function.
6. Only a window can accept messages, unless you create a custom message mapping, sending, dispatching, ... mechanism. So a CWnd object or derived classes can handle a message.
...
LRESULT OnSomething(WPARAM wParam, LPARAM lParam);
DECLARE_MESSAGE_MAP()
...
BEGIN_MESSAGE_MAP(CMyClass, CDialog)
...
ON_MESSAGE(MyTestMessage, OnSomething)
END_MESSAGE_MAP()
.
.
.
LRESULT CMyClass::OnSometing(WPARAM wParam, LPARAM lParam)
{
return 0;
}
