That's the 'perfect forwarding' problem[^], that will only be solved well with the introduction of rvalue references in C++0x.
I would suggest you take a look at the implementation of Boost.Signals[^] - that does exactly what you're trying to implement (by which I mean the delegate concept).

Hello everyone,
Thanks a million for all the help you have all provided so far.
I would like to use the CTabCtrl. All the searches and examples I have been through in order for me to use it I have to create a TestTabCtrl class that is derived from CTabCtrl class and create a CPropertyPage class.
Please could someone confirm this for me or have I missed on other ways.
Thanks a million.

Hello,
I have a CRichEditCtrl box on a CMDIChildWnd. When I move the mouse over this edit box its cursor changes to caret pointer indicating that the box is there. This CMDIChildWnd is made by Create()of CMDIChildWNd
Now when I make a Child window by CreateNewChild() and the add CRichEditCTrl on the childwindow the edit box is seen but when I move the mouse cursor on the edit box the cursor doesnt change to caret pointer .
What is the difference or what must be the problem in making child
windows in diff ways?

Hello,
i managed to rotate a rectangle 45 degrees. Now i have an picture that i need to map to this reversed rectangle. I heard there is an inverse mapping way. Something about u and v. I am not familiar with it. Can someone tell me how to use this?
thanks

You've set yourself quite a difficult task. There isn't a normal windows "draw a bitmap using these four arbitrary corners" function.
The nearest I can find is: Graphics::DrawImage, part of the GDI+ library. But it will take some learning to be able to use it from scratch.
Good luck,
Iain.

Recently, I download a bunch of sample C++ programs from the URL: http://msdn.microsoft.com/en-us/library/7zx6z2e4.aspx. Unfortunately, I have been unable to build any of them. When I open up the project file and click build, I get the following output from the build:
1>------ Skipped Build: Project: Cube ------
1>
========== Build: 0 succeeded or up-to-date, 0 failed, 1 skipped ==========
When I try compiling just one of the sample programs, I get the message:
Operation could not be completed. Unspecified Error
This message appears in a “bomb box”. I am wondering if I am doing something wrong, or are these projects just bad? Please help.
Thanks
Bob

David,
Thanks for the response. Yes, when I say project file, I mean solutions file.

i am trying to plot a 1D line graph with in an openGL window in a MFC Dialog
there should be controls to zoom-in , zoom-out, scroll and also select a specific part of the graph such that i am able to get the values of the lower index and upper index of the selected part of the graph.
i am building this application in VC++6.0
Any help would be deeply appreciated.. Thank you

I am in the process of learning openGL also. I also found an example called cube that Microsoft
offers. This example can be found at the following URL:
msdn.microsoft.com/en-us/library/7zx6z2e4.aspx
However, I was unable to build it. I am not sure why. Maybe you can. In any case, it does seem like
nice demo program.

Thanks for your help 
but i'm trying to build an application in a dialog based project
the url you suggested give info about Single Document Interface(SDI) project..
"The CUBE sample is a simple OpenGL application. It demonstrates how to integrate OpenGL with the MFC single document interface (SDI), and how OpenGL's resource contexts are used in conjunction with device contexts."

There's very little work in taking the OnDraw part of a CView object, and putting it on the OnPaint method of a static control on a dialog...
So the techniques in the article are still worth reading.
Maybe this article will be more help?

Hello, guys.
I am having trouble mixing two audio files.
I am looking for some info on " Mixing Two Audio files using the Right Shift by two bits".
Any kind of help is much appreciated.
Thank you.
|
|
|
|

How are you attempting to mix your two audio files? Are you writing a program, using a commercial progarm, or what?
And, really, you should tell us: WHAT FORMAT YOUR AUDIO FILES ARE IN. (that might be important)
