Then you should create a dialog template (through the resource editor), then create the associated class. Then, on the button function handler, create an instance of this class and call DoModal.
If you want to pass some parameters, then add a new function in the class (that receives the data) and use these parameters in OnInitdialog. This new function is called before you call DoModal.

receive the data? I mean, if say i have in the main frame's class an int data;
and then it's initializrd in the application by say data=10; how do i write the function on the new dialog that gives me data's value?

You only need to show some parameters value in a string for example ? Then it is much easier to go for a simple MessageBox.
Here is how you can do that (let's say that you want to show the values of Param1 and Param2 wich are both integers):
char szString[255];
sprintf(szString,"Value of Param1: %i, Value of Param2: %i",Param1,Param2);
MessageBox(szString);
(I suppose you put this code in a class derived from CWnd).
Take a look at the doc of sprintf[^] for more details.

mmm
then you need this:
<br />
CString String;<br />
int N=5;<br />
String.Format("parameter1 is: %d", N);<br />
AfxMessageBox(String);<br />

wouldn't that print out : parameter 1 is=5 ?
i need the real value of param 1

My application is reading data from serial port. But the data may arrive at any random time. So i want to interrupt the application when data arrives on the serial port. Can anybody suggest me some solution to this problem.

You won't be able to use hardware interruptions in your program (and it's bad design also  ). A better solution is in general to spawn a thread that will poll the serial port for data. A good design for doing that is starting this thread in a separate class that will send a message to your application when data is available (custom message). This may sound 'complicated' but if you don't want to freeze your GUI, it is the best way of doing that.

From my experience in the past, polling eats processor resource even though we have added something in the loop in the thread like Sleep(1).
Personally I prefer to feed an event to the serial port API, and use WaitForMultipleObjects or WaitForSingleObject ...

Yes this is so true! Basically all those communication related applications have to be designed in multi-threading to prevent from GUI frozen.

Use Overlapped I/O and WaitForSingleObject

Is pTmpl initialized? In your example there isn't any init.
if yes what about pTmpl->UpdateAllViews(NULL); ?;)

How can i understand the child window which i got is of child dialog?

i want to know if pWnd is of child dialog?

I'm not sure that I understand your question, but I think that if you want to know what kind of object is pointing pWnd you could use
if(! pWnd ->IsKindOf(RUNTIME_CLASS(CChildClassName))){;)
//Error
}else{
...
}
|
|
|
|

Hope I understood your question
see IsChild[^]
and CWnd::IsChild

i got the child window using CWnd* pWnd = GetWindow( GW_CHILD );
but the pWnd i got is of the edit control of the parent dialog.
i need to get only the pWnd of child dialog and not of child controls.

Use pWnd=pWnd->GetNextWindow() in a while loop and exit when the pWnd points the right object.

Do you wish to check pWnd is a Child dialog or pWnd is a child of a dialog.
Use GetParent to find out the parent and then use GetClassName to find out the class.
You can also refer GetParentOwner.

What he need is to check whether a window ( got from hWnd ) is a dialog window or a child control ( means edit, static, etc. )
