Hi,Everyone:
I got following questions:
1> i want to transform a wave's format to standard format i needed(such as 8000HZ,16 bit,mono,signed) we can use software Goldwave’s “Effects->Resample”. But are there any classes or functions in VC?
2> we aslo want to transform the standard wave (we get from the first step) to A-Law PCM Signals.
How can I realize that in VC? Can any of you give me some threads or links?
Thank you very much!

Hi all,
I've a MFC dialog with a button and a CTreeCtrl at the dialog.
My dialog is resizable and when resizing the dialog I observe flickering.
First: In the OnPaint() method, I've made a second DC (Device Context) on the memory and disable the WM_ERASEBKGND message.
Second: I fill the DC with the background colour and then I use the BitBlt() method to switch to the memory device context.
Could anyone suggest me how I can make copy of the CTreeCtrl in the memory device context.

Hi
(what you're doing sounds a bit elaborate)
If you're only concerned with the flicker, you can set the dialog's style to include WS_CLIPCHILDREN - this way, the dialog and the control don't compete at drawing the same area. Try it and see if this solves your problem.
You can set this property in the Resource Editor too.

Tree controls are a bit tricky to double-buffer, as they occasionally draw outside of WM_PAINT . In controlled situations though, it should be possible. Look into WM_PRINT for a way to force the tree to draw to a specific DC.

Hi,
How can one implement calls forwarded to another DLL. For instance, how is it possible to create a DLL that exports symbols forwared to another DLL.
For instance, kernel32.dll exports RtlZeroMemory via a fowarded call to ntdll.dll. Can I make my own DLL export symbols via forwarded calls to other DLL ?
Cheers.

Hi
I need to ensure that an object of a one of my classes only gets created on the stack as opposed to on the heap using 'new'. Is there a compiler keyword (I'm using VC .net)
or some other method to ensure this.
Thanks

I'm not a guru, so take this as a SWAG:
Maybe you could override operator new for your class, and let it throw an exception if invoked?
Or did you mean that operator new should allocate the object on the stack instead of the heap?, in that case, I would say: Not recommendable. (And probably very hard to implement).

Thanks Jan
I should have mentioned that I was actually looking for a compile time solution.
Serqe's solution seems to be what I was looking for.

you need to declare the operator new as either a private or protected; for example:
class A
{
private:
void* operator new(size_t);
};
int _tmain(int argc, _TCHAR* argv[])
{
//error C2248: 'A::operator new' : cannot access private member declared in class 'A'
A* pA = new A;
// OK
A a;
return 0;
}

Thanks Serge
This is exactly what I was looking for.

Hello all,
Visual SourceSafe has long been a popular choice for source code control and file management purposes. As collaborative team becomes a prevailing form, it is common now to have members from different geographic location sharing source code and other files when working on a project.
SourceSafe is designed for project teams on local network, this is why we need a tool enabling each member to easily connect to VSS database from anywhere with internet using.
Software purchasing, unlike selecting other IT commodities, will arouse non-retrievable loss in case the potential bugs of a product. So reliability should be regarded as the primary request for a SCC tool.
With several years of experience in this domain, I'd like to help you with some good suggestions as I can if you meet any SCC problem and you trust me.
Anyway, leave me a message.
Regards!

Now, listen very carefully webcrap, because I will say this only once: this is NOT the place to advertise. If you want to advertise, you can support CP by buying banner space.
If you'd care to step into the Soapbox, I will happily provide you with the facts as to where you can apply your product.
