Uuh ?  Sorry but I did not understand what you are trying to say. You need to explain that part a little bit clearer. What are you doing exactly with this class ?

Are you wanting only one instance of the DLL, or one instance of a class within the DLL?

I believe these are called singleton classess. Be sure the constructor is private.

Yes I now but my class work in my project very good I get only one instance but now I have put my "singleton" class into a DLL and the instance that I get from main app is not the same that instance that I get from a class into a other DLL.
That is my problem !

Each user app of the dll will get its own data memory so oneinstance will be different for each app.
You need to look at using shared memory in the dll so that all apps share some or all of the dll's data. It may be a much more difficult issue than it seems because of synchronising access and so on.

Hi,
Did you try to put HANDLE GetCurrentProcess() instead NULL in GetModuleFileName?

Huh?
So you don't want the path of the running executable?
You want the path of another running executable?
Are you talking about GetCurrentDirectory()?

I think he needs to path of his program

 I read first his question "retrive the path of current running application"
|
|

|

ya you are correct.I want to retrive the path of the running application not the path of executable file path.Because i gave the path of executable file different(C drive).But my application is in D drive.
Thanks.

Hi,
Here's the problem:
(a) I'm wanting to have multiple child windows showing different aspects of a single document
(b) I've created some CFrameWnd objects as children of the main view (main view is the primary CView object created by visual studio sdi app. wizard)
(Problem) They are always in an inactivated state - even when clicked on. They have been created with the WS_CHILD | WS_VISIBLE | WS_OVERLAPPEDWINDOW styles and they seem to do other stuff o.k. (resize etc). Creating my frames as children of the top level frame doesn't help either.
(d) I think its the same problem as posted on the MFC archive at:
http://microsoft.ease.lsoft.com/scripts/wa-msn.exe?A2=ind9811d&L=mfc&T=0&P=4761
which never got a response 
If anyone could offer any help or advice it would be great
Thanks,
Ben

Use the MDI application model. The MDI model has everything you want already built into it.
You may be right
I may be crazy
