Hi all, I am trying to write a program that runs in background to monitor and kill some running process. I coded it in Visual C++ 6.0 in a Win32 Console Application project. The code works, just that the console window appears when I run it. Can anyone tell me how can I make it a background process without the console window showing up? Thanks and appreciate.

There are a bunch of functions for dealing with consoles. Search for "Console Functions" in MSDN
Something like this might work ::ShowWindow(::GetColsoleWindow(), SW_HIDE);

I am trying to load an dll written in vb in my MFC dialog program. Does anyone know how to do this? Thanks.

Is it a COM dll ? Then the fact that it's VB is irrelevent. Can you #import a VB COM dll ? I don't know, but if you can, that's the nicest way to use a COM dll.

It is infact an ACTIVEX dll. I've follow the steps from the this article, but I still get errors when compiling. (http://www.codeproject.com/dll/vbactivexwithvc.asp[^]). The generated .tlh file contains a method from the dll file which generates the error.
HRESULT OUT (
unsigned char OUTNUM,
VARIANT_BOOL VALUE );
error: C2027: use of undefined type 'HRESULT'
Thanks for following up.

ActiveX is COM, that's why it returns HRESULTs. What sort of project are you creating, that it doesn't contain any COM stuff ? afxwin.h defines HRESULT, it's just a long.
This article is showing you how to do things the hard way, unless it's impossible to #import an ActiveX dll and then instantiate it the same way you do other COM dlls.

You can definitely #import an ActiveX component - I've had to do that many times including a current project that uses the MS Script ActiveX control.

Yes, but can you use code like this:
HRESULT hr = File.CreateInstance(__uuidof(Avi::AVIFileInProc));
or do you need to use the CreateObject type code the article was providing ?

Bascially, I just want to import this dll in a vc++ class and use its functions.
Since this dll is given by another person, I cannot change its format nor obtain the orginal source code.

That doesn't matter, I'm saying that if it's a COM dll, I don't see why you need the messy code that article gave you.

Hello, is there a way to play multiple sounds (.wav files) using managed C++ in .NET for my application? I am a newbie so I need details.

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.
