Windows media player

Hi all

I have managed to get windows media player (active X control) to play, pause and stop music files. But it only plays a file that is preloaded before running the program.

Is there anyway I can get the player to accept and play a file chosen by the user. I have only suceeded to get the program to show the open file dialog window but it doesnt play the selected file.

Any ideas on how i can get the file to play? Similarly is there a control i can use to load a play list?

I'd be grateful if anyone has any sugestions on this

I'm afraid I don't have the code here, but I've definately played playlists and files from C# using WMP. From memory, you actually get an object that represents the file to play by calling a static load method on the playlist, then you set the current file to be that object.

get winhttp server using HINTERNET handle?

hiho@ll

anybody knows how to get the server-ip (oder domain name) if i have an HINTERNET handle?

i'm using a CHTTPClient i found at codeproject which uses WinHttp
i connect to a server, which redirects (using the Location response header) to another server
the connection handling of winHttp does everything right, but i just want to know to which server i'm really connected!

i tried HttpQueryInfo
but this uses the Host header field of the http request
and this header field isn't set because of the Location field of the server

so anybody knows a function, which tells me to which server i'm connected using a HINTERNET handle?
thx@ll

Hi,

is it possible to use Riche Edit Controls for non MFC dialog based apps?

When I insert such a control, I dont see anything. I googled a bit, and found out that I need to call AfxInitRichEdit2. But this one is for MFC based apps. I dont use MFC and I dont want to.
Is there any way to use them? I couldnt find a function to initialize it.

make data retrieved once, and be available to the whole application

I have to read some data from the registry, and will need to use it several times in probably all the parts of my application.
So instead of reading it from the registry every time I need it, I would like to read it once and make it available to all the application parts.

How can I do that? Confused | :confused:

I thought about the Document class but I have more dialogs that can't access this one.

Thanks

Make the data global. The simplest thing to do is to place it in stdafx.h, marking the declarations with the extern keyword. In the main program, where you retrieve the data from the registry, repeat the declarations without the extern keyword.

Hello!

How can I open .col files with hh.exe? I already installed the latest version of HtmlHelp Workshop and tried to run the hhupd.exe, but it tells me that I got a newer version already (I'm using Windows XP SP2).

Do I have to install any update? How to make hh.exe open .col files?

Thanks in advance and best regards

Dynamically import classes from a win32 DLL

Hey guys,

Anyone knows about how to dynamically import a class from a dynamically loaded win32 DLL. ( I dont have the .lib file nor the header file for the dll) but i know the names of classes in the dll.

furthermore, can I (using VC++ 6) import classes written in VC# 7.0 as a DLL and use them in my VC++ app?

Need help plz Frown | :(

Regards

Well it's tricky. What you usually do is define a function that creates and returns a pointer to a class and then a function that destroys the object passed. If you don't have the complete class definition, this is as good as you'll get because you will never be able to create an object yourself. How could you without it's definition? The compiler requires this, even pointers to functions imported from DLLs are defined before they are used. Search www.deja.com for "import classes from DLL dynamically" for more information.

There is even a better way: use COM Wink | ;)

But in that case without the source code it's quite tricky. What kind of DLL is it?

Don't try it, just do it! Wink | ;-)

Really its tricky, the problem is that the DLL is created with Visual C# 7.0, but I want to import its classes to my project, which is a VC++ 6.0 project, I dont even know if this is possible. (are these two languages compatible?)

Any help will be appreciated.
