Thanks WhiteSky, I went to the help first off. But, the threading model is the same throughout the project. No 3rd party libs or anything that are different threading models.

I think you are trying to use a 3rd party library which is using a different C Run Time then your main application. By looking at error I think your application is using /MTd but at least onee of 3rd Party library is using /MDd. In case it is true then you have to recompile all 3rd party libraries using same CRT.

Hi,

I'm trying to create a custom slider. I've got 5 bitmaps that show the slider's know in 5 different states.
All that is left to do is to change the bitmaps as the user drags the slider.

I've looked in all the articles on the site. All of them use a different approach with regerd to custom drawing of sliders: the knob, the channel and the background are independent objects. I couldn't find an article that implements dynamic replacement of bmps as the user drags the knob.

Can anyone shed some light on what's the best way to implement it?

Thanks a lot in advance.
Snir.

I include windows media player as a control in my MFC app by VC++.net 2003. The problem is that I need to turn off the original events in media player such as right click or double click in the playing area. The right click event in media player will open a popup window while the double click event will shift the playing area to the full screen mode. How can I turn these events off in my app?

How to use DirectSound to specify mono sound in to left or right audio out

Hi, I am developing a software to make use of a 8 channels audio in/out device with direct Sound. We want to capture mono (single audio in) sound source and play to a specific audio out (mono). However we find that the DirectSound always treat the device as stereo. Nevertheless, we can separate the source from left or right audio in, but there is a problem in making this sound to be output from specific audio out (left or right).
For example, we have captured a sound on left audio in and want to play it on RIGHT audio out. But we don't know how to do it. Can anyone help?

First of all you don't need call to UpdateData to display String in ComboBox and related Controls.
Secondly you have to increase display size of Combo to see inserted string.

Have you included the header file that defines the CMySocket class?
