DirectX is what you need. You need to download and install the SDK ( which means the runtime is required for your app ). There is sample code with the SDK.

Thanks for the reply, and this may sound stupid, but I dont know what SDK means, or how to use that with Managed C++ .NET. Would a tutorial be provided?

SDK stands for software development kit. Basically, it's a load of files that you need to use a library that didn't come with your compiler. Yes, if you google DirectX and go to the Microsoft site for downloading, the installer will give you all you need, docs included.
BTW, if you're starting out, why did you choose managed C++ ?

Thanks for the help, and to answer your question, I was provided with Visual Studio .NET, and I wanted to make a forms application. Since I prefer C++ and I heard MFC was hard to understand, so I went the Managed C++ for my forms app.

Honestly, you're headed into hell. I love doing winforms in C#, much easier than MFC in C++, but MFC is not really hard, it's just that C# is easy. And doing winforms in MC++ is my personal vision of hell. But if you have a deep understanding of C++ already, and you don't know MFC, it may be a toss of the dice. It's certainly, definately, not going to be easier than using MFC though, and you end up with an app that requires the .NET framework. Why have that if you don't need to ?

In all honesty, I have only been programming for about two years, and most of it has been basic console programs with C++. I was going to be an architect. This is all very new to me, and I have tried other languages, but it doesn't mean I'm not open to others. I understand .NET MC++ easier than the others I have tried. I've heard C# is easier and it looks exactly like C++ to me. Thanks for the information though, maybe I'll investigate MFC.

I don't know what you've tried, but MFC apps are pretty simple, if you know a bit of C++. The framework is not perfect, but it's a huge improvement on Win32. C# looks a lot like C++, so it's easy to move, and it's definately a much easier way to get to WinForms than MC++ is.
I'd investigate C# and MFC as good alternatives. DirectX is available in both, but it's a ton easier in C#, because C# handles all the COM pointer stuff for you.

Now I'm extremely intrigued. Most of my application was written in MC++ and if I were to transfer it over to C#, would .NET still create the .exe file, and would I get that Resource Editor GUI that is provided? If so, I'd switch my application to C# right now.

There's no automatic conversion, but you could certainly put your existing non GUI code in a dll and call it from C#.

I believe the resource editor in C# is better than the C++ one, unless MC++ gives you the same one.

Not to prolong this, but how would I put all my code inside of a .dll and call it from C#? If its too complicated, or takes too long, I might just re-write everything to make it more efficient and learn C#. As long as I can have the .exe and the Resource Editor, I'll be fine. Thanks for the information, I love programming epiphanies.

Well, you'd basically create a managed C++ dll and move the code into it. Your current project would be set up to create an exe. If the code can be easily ported to c#, I'd do that instead, the cross language thing could be a pain later.

One last question, then I'm all done, and I greatly appreciate the information:
Would you happen to know how to add a double buffer to a Panel? In C++ I did this:
Panel->SetStyle(ControlStyles::UserPaint, true);
Panel->SetStyle(ControlStyles::AllPaintingInWmPaint, true);
Panel->SetStyle(ControlStyles::DoubleBuffer, true);
However I got errors about accessing SetStyles when it is of type Panel. However, I paint everything on the panel. Is there a way to add a double buffer?

I use those same calls to make my app double buffer. I wonder why you can't do it to a control.
I draw all my images myself, and if you do that, you can certainly set double buffering up like that in your main window.

A piece of advice - the MVP next to Christian's name means "Microsoft Valued Partner" and there are about 70 for C++ on the planet so you have one of the top guys around helping you out.
I would suggest MFC too, the DirectX SDK comes with lots of examples including ones on playing sound.
Basically you put individual sounds into secondary buffers and they are combined into the output buffer which goes to the output device.
For samples under 1MB you can just read them into the secondary buffers, above that it is reccomended you use streaming into the secondary buffers.
I hope this helps.

To answer the original question (at least for C++):
If all you want to do is play wave files, then you can simply call the PlaySound function. If you need to anything more sophisticated like mixing sound files together, etc. then you'll probably need DirectX. But for basic wave files, the PlaySound function is very easy.
From regular C++ (someone else will have to help with proper imports for the managed environment):
#include "mmsystem.h"
#pragma comment( lib, "winnmm.lib" )
void SomeFunction()
{
PlaySound( szSoundFileName, NULL, SND_FILENAME | SND_ASYNC | SND_NOWAIT );
}

Hi everybody,
I need a fast help drawing a line (function lineto) on top of a programmatically created Cstatic Control.
I tried setting back with SetWindowPos(&wndBoottom... but nothing.
Do you know any way or i should create a custom line control?
Thanks in advance.

A CStatic only contains text. You'll need to make your own control, best bet IMO is to derive from the static and owner draw.

Assuming m_Static is your static control:
CDC *pDC = m_Static.GetDC();
pDC->MoveTo(0,0);
pDC->LineTo(100,100);

Hello,
Derive a class from CStatic using Class Wizard. Draw enough code in OnPaint(...).
Is it OK?

the problem is that i have a window and a Cstatic control on it. I have to draw a line that goes on both. Knowing this, are your solutions still valid or i shoul build a bevelline(that what i need) class and set it's position with SetWindowPos?
tnx
|
|

|

I feel you have a better method than me! It will be fine if you set the zorder of bevelline control to the top of the static control in SetWindowPos(...).

i am working on a Database project thats one table in its Database contains an images, i am retrieving data with CRecordset.
the problem is when i try to get the retrieved data from CLongBinary to bitmap, i try:
////////////////////////////////////////////////////////
bitmap.FromHandle(HBITMAP(varValue.m_pbinary->m_hData));
::OpenClipboard(this->GetSafeHwnd());
::SetClipboardData(CF_BITMAP,HBITMAP(bitmap));
::CloseClipboard();
////////////////////////////////////////////////////////
but i colud not paste the data from the clipboard to Microsoft Paint.
any one has an idea about this.
