Please do not shout, or fix your CAPS LOCK key on your keyboard.
As for your question, DDX_ is an MFC macro that maps one of the controls you have created in the resource editor (IDC_THIN_PEN_WIDTH) to the member variable (m_nThinWidth), so that you can access to the control using the member variable.
For advanced user, it is possible to mess with the MFC macros; however, unless you are trying to do some advanced code, if you have to change a macro, it points out a bad design. What are you trying to achieve exactely ?

thanx for the explanation.

The way to figure this out for yourself is to place a breakpoint on the DDX_ line, run your program in the debugger and step into the DDX_ code.
You will then see what DDX_ does, and with a little help from MSDN you can easily figure out how to write your own.

Hey guys
I have a simple dialog based MFC in which I have removed the title bar area from property of dialog as I want to show that dialog in fullscreen. Also I have opened another smae kind of exe. now when i terminate I want to terminate the other EXE also. But my both the EXEs don't have either classname or caption. So how to close it ?
For that first i need to find handle of the other EXE and for this i use FindWindow() function. Now it requires classname or caption. Is there any way to assigne classname or caption so that I can find that window.
Any idea....
Or is there a way so that I first assign window name to one of my window and at run time I can hide that caption. ?

AFAI, with GetWindowsText, you can retrieve the "name" of your window. The fact that you does not show the caption does not remove the member of the dialog class containing the name, it is only not shown.

You can do some interprocess communication.
In the second application use RegisterWindowMessage() to register a custom user message, and capture that message using WndProc().
In the first application (full-screen), when you are exiting, register the custom message, then send it to all windows using:
::SendMessage(HWND_BROADCAST,id,0,0); //id is id of the message returned by RegisterWindowMessage().
The second one will catch it in its WndProc() then it can exit.
this is this.

Use ::SendMessageTimeout instead or your application might hang on the first app that is not processing messages - I can already see myself shouting this from the grave

Are you using CreateProcess() or ShellExecuteEx() for this? If so, then just retain the handle of the new process. You can then call TerminateProcess() using that handle. Another option is to send that other application a WM_CLOSE message.

In the MFC exe version,i created a thread just to protect the GUI from freezing, but is it actually need inside an ATL dll?.. the dll's going to be used by a VB application, i guess it wont freeze the VB application, but is it recommended to use threads even inside a component(ATL)?
ie, its just a do while loop
void simpleFunction()
{
do
{
}while();
}
or
UINT ThreadFunxn(LPVOID lp)
{
do
{
}while();
}
which one can be right inside a DLL?
thanx

You already know the uses of both approaches. If it is a small operation, then it will do fine without threading.
If it is lengthy, then you should use threads. Inside the threaded version, you can report back by firing events that the operation is complete etc. Also you need to make sure that the object created in VB stays alive (global) as long as the thread inside the dll is running.
Maybe someone else can give some better explanation.
this is this.

AFAIK,This some time can be complecated... let search some documentation regarding it and will revert back to you for further discussion..

This could be a tricky one! VB and threading are like water and oil, they just won't mix well together.. at least that's what everybody is saying, including Microsoft. The thing is, if you're thread is created within the DLL and you only call the function that spawns off the thread from VB you should be OK; but only as long as you initialize OLE on that thread using CoInitialize() and then uninitialize it before the thread exits using CoUninitialize(). That is critical!!! Other than that, make sure the thread is dead before you close VB... or else  ...

Let say I have a server and client Dialog to send message through TCP/IP and I just read the MODBUS frame that have Transaction Identifier, Protocol Identifier, Length Field, Unit ID, Function Code & Data. How to write a program into the send button that when I type and send a data, it will add all the address infront of it?

What kind of question is that? Can you be more precise in your questions? I will have to ban you if you continue to post such questions!
Thanks for your cooperation.
I have reviewed your profiles and discover you have various identities and post questions which are irrelevent and i might say is stupid. So i ask of you to stop posting such questions.
