Hi,
CamStudio[^] does precisely that and is open source (written in C++). You could use it as a reference project to build your application.

I use the free jing, from the TechSmith (Snagit) people.
After you have captured the swf, you can share it online using the free (2GB storage and 2GB monthly bandwidth) screencast.com service.
Highly recommended.

Simply use DX native functions.
C++ Code is in MS SDK.

Hi,
I want to wait for all the event to finish and only then continue my program and im looking for the command in c++,
I have the command in c "g_main_context_iteration" and im looking for something similar in c++.
thank you for any help
|
|
|
|

You should provide some g_main_context_iteration to your question. 
Since g_main_context_iteration (of the GLib library) is a C function , you are free to use it in your C++ application.

the command is - while (g_main_context_iteration(NULL, false) == TRUE) {}
and i have problems using glib and i search for alternative
|

Well, GLib (I guess) has its own programming model that you won't find in other frameworks (or in bare Win32 development). What kind of application do you intend to develop?

Hi to All,
Could anyone please tell me, how to implement the divide operation by using shift operator....
I know that, if we right shift by n..number will be divide by (2 to the power n)....But, what about other numbers?...(say 2*3)...please help me out
thanks in advance
-----------------------------
I am a beginner
|
|
|
|

If the divisor is not a power of two, the shift operator alone can't do the trick. You may, for instance mimic the divide operation you perform manually, porting it from base 10 to base 2.

Hi,
I'm trying to create a driver, for which I use WinDDK 7600.16385.0
But when I add a *.lib file, the linker still gives "unresolved external symbol" errors the same as if I haven't added it at all. I know the linker looks for the *.lib file, because I checked - I renamed the lib file to something else and the linker immediately complained that it can't find it. Does anyone here know what might be the problem?
I've referenced the lib file and the include files' dir in the sources file of the driver:
TARGETNAME=driver_drv
TARGETPATH=obj
TARGETTYPE=DYNLINK
TARGETLIBS=$(SDK_LIB_PATH)\winspool.lib \
$(SDK_LIB_PATH)\user32.lib \

Did you ever figure out how to use the WinDDK with MFC? If yes, I'd so much appreciate it if you could tell me your project settings!
|
|
|
|
|
| Can't you just use win32 for whatever dialogs you need to show? You usually shouldn't embed any gui code inside a driver anyway. It works in XP but wait till you see how it behaves on Win7.

I'm trying to create a DLL that links to the DDK, with a COM object as my interface to the DLL... Can this be done without MFC? (there are no dialogs at all)...
|
|
|
|
|
"with a COM object as my interface to the DLL"
Could you clarify this?
COM even can be made in plain C (not C++), so you certainly don't need MFC. MFC does offer some handy classes like COleDispatchDriver that make working with COM easier though. I think you can use ATL instead, which has alternative classes.There is sufficient light for those who desire to see, and there is sufficient darkness for those of a contrary disposition.

I need to create another project with its own import settings, so I thought a DLL would be my best bet, however I never understood how to properly export functions other than with COM. Using the "New Project" dialog in VC++, I thought my only option was to use "MFC DLL". You're saying otherwise though and that sure sounds good.
What type of project should I create? And how do I add my COM class to this project once it's created?
|
|
|
|
|
| Am I getting this all wrong? I thought you wanted to make a driver, but now you talk about New Project with VC++,COM and etc., which has nothing to do with drivers. WinDDK isn't VC++, it's a framework for making drivers (like network/usb/printer/display drivers). Sorry, just have to make sure we're having the same thing in mind, otherwise we'd just confuse each other. There is sufficient light for those who desire to see, and there is sufficient darkness for those of a contrary disposition.

Well not a driver, but a USB HID device - so sort of a driver? I've got this credit card reader that is a USBHID device - so you need to use the WinDDK. Here's my story - I actually got this working in VC++ 6.0 about 3 years ago and now I can't figure out how to setup my project anymore. But that's just what I did - I created a COM object and linked to the DDK (from VC++ 6.0). Now I've upgraded to VC++ 2008 and just want to take the best route - if I have to learn the right way of doing it along the way, BONUS! I'm all ears. Just because I got it working before doesn't mean it was the best way of doing it anyway - and just the same, I can't get my project linked with MFC.

| Yes, I see now why you were talking about VC++. The thing is, WinDDK comes with its own compiler, which is 'annointed' (i.e. official and supported) by the DDK development team. WinDDK is intended to work with it. Now, that doesn't mean it won't work with other compilers - you've made it work with VC6, but that's not how it's intended (by microsoft) to be compiled. What I did was I used their official compiler which comes with WinDDK and is in fact in the directory (C:\WinDDK\bin or something). So if you really want to use VS2008 I can't be of much help because that's not how I did it. I used the WinDDK official compiler. See if this thread (http://www.osronline.com/showthread.cfm?link=151863) can help you, they talk about how to make it work with VS2008 there. There is sufficient light for those who desire to see, and there is sufficient darkness for those of a contrary disposition.

Hi
I'm having a mfc dialog box application as a dll. I want to send any event (button press) in the dll to the application that calls the dll. how to do that. Anybody can please help me.
Thanks

May be you can pass the handle of the main window to the dll( in some initilization function ) and when button click occures you can send a message( RegisterWindowMessage() ) to the main dialogbox from the dll indicating the button press.
|
|
|
|

thanks. I could do by Inheritting the dll class and implementing the virtual function.
Thanks again
