I appears that RIFF WAVE "format" chunk has an additional and so far unidentified variable.
It suppose to be used when the wave compression format is different than 1 = no compression.
That is why the actual data chunk identifier "data" was missalligned.
I'm just being lazy here but is there a way in the Visual C++ IDE (any version) to have it tell you what exceptions have been declared (by any of the methods or methods called by those methods etc...) to be possibly thrown?
The only way I know of is to dig through MSDN researching each method call which can get time consuming since there are so many overloaded method variations that I tend not to assume the possible exceptions that could be thrown by one overloaded method will be the same as another overloaded method.
WinError.h contains all of the error codes generally thrown by WinAPI/MFC calls, but generally speaking, there's no clear way of knowing what each method will throw without looking into the documentation associated with that specific method.

I'm just trying to quickly identify which catch handlers (if any) I would need at the level in the code where I'd want to handle them. Maybe some magic hover help that would allow you to see the summary of all the "throw" declarations for the method call, definition, or declaration your cursor is currently hovering over.
I apologize that I didn't word my question very good, now that I've reread it I guess it did sound like I just wanted a list of all the exceptions that could ever get thrown anywhere.
A basic rule of exception handling is also that you only handle exceptions that you are aware and knowledgeable of. You shouldn't just catch any and all exceptions, except for maybe at the top level of your code.
So, you need to look into the documentation to see what exceptions are thrown and how to handle them anyway. It'd still be nice indeed to see what exceptions could be thrown so you can quickly check what you'd have to handle, but I'm guessing the documentation is quick enough for it anyhow, since you'll need to refer to it anyway to understand how to respond to the exception.
I want to send TVN_BEGINLABELEDIT message from a custom tree control, whenever i will press F2 key( to rename the label ).In custom control I have handled PreTranslateMessage, in which after mapping VK_F2, I have written
Now when a selection changes it calls OnCbnSelchange message-handler. I am using this class inside a dialog class. I have tried to register a message handler in that dialog class for CBN_SELCHANGE event but I think it is not receiving CBN_SELCHANGE event or it is sending that event to custom control. How can I handle CBN_SELCHANGE event inside a dialog class.
This is the implementation inside derived class (or custom control class)
// TODO: Add your control notification handler code here
GetLBText(GetCurSel(),m_str_sel); //get previous text in combo.
It's a long time since I used MFC message maps, but it looks to me like you are capturing the CBN_SELCHANGE notification in your control, so the dialog box won't see it. I think you may need to move that notification to the dialog or reflect it back somehow. Pual Di Lascia wrote an excellent paper[^] on MFC message processing which I recommend to anyone struggling with this subject.
What do you mean by drag? If you are trying to move it to a different window then you need to implement drag and drop as described in some of these links[^]. If you just mean that you want to move the control around within its parent window then you just need to capture your mouse and redraw the control at whatever position the mouse takes you to.
