Make a copy of the table that the stuff gets imported to. Ensure that this table is empty. 2) Import all your stuff to the secondary table 3) If there are no exceptions then delete everything in the original import-table, and copy all stuff from the secondary table to the import-table. If an exception did occur, the original import-table will still hold all data. You could also use transactions to achieve a similar functionality. SQL Server caches all changes that way, in order to 'undo' them. I don't know which of these options would serve you best. The transaction-approach would probably be faster to implement.

Yeah,you can use of MCI for play mp3,wav,mpeg1,mpeg2,avi files.

Hanan888 wrote: Are you sure this applies to the latest SDK? yep, but not in Direct3D 9(though 9 is not latest) since directdraw interfaces are outdated in direct3d9. It is used latest directshow sdk, where VMR7 is supported by this IDirectDrawSurface interfaces while VMR9 is supported by IDirect3DSurface9 interfaces. Haven't you seen this "The IDirectDrawSurface interface is exposed on DirectDrawSurface objects that are used in the DirectShow multimedia streaming APIs" in that link. you can also refer some samples in DirectShow how custom allocator are implemented to mix various video streams much similar like your requirement.

It is part of DirectX, for some reason MS changed the way they update DX, when you apply an update, instead of updating the existing dlls, they simple add another one.

see here[DirectXSetupGetVersion^], winxp shipped with default directx 8.1, while windows XP SP2 updates to directx 9c. See the API DirectXSetupGetVersion which gets the version of directx currently installed in the system, if that matched or higher you can run your application or install programmatically or ask user to install the required directx version runtime. [Added] And DirectX SDK has samples demonstating these (1 )DXInstall_(DXInstall is an example of how to use DirectXSetup interfaces to install the DirectX subsystem and DirectX drivers)_ (2) GetDXVer (to get the version of directx installed) [/Added] modified on Thursday, May 22, 2008 1:35 PM

Thank a lot. Don't have time to 'stitch' it now but first thing after the weekend :)

Thanks again, I'll try that.

Thanks. It has dynamic rendering, to be specific, it plays series of pictures according to time (what might be called animation). So it must repaint all the time.

Means, it transparent blitting is not happening? possibly you are setting the palette index as 0x00 which may not contain the white color. why don't you use 0xff only and set the color white in the palette entry at 0xff when the palette is created.

Thanks a lot

I made a test, you're right. :) If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler. -- Alfonso the Wise, 13th Century King of Castile.

:laugh: Yeah I know, but I also have seen things like if you are just doing 2d you don't need the overhead of the DX interfaces and libs which have been designed for 3d. led mike

Can you show the code? What are you calling ReleaseDC() on? The CImage object? You shouldn't be using CImage::GetDC()/CImage::ReleaseDC() when using CImage::Draw(). Mark Mark Salsbery Microsoft MVP - Visual C++ :java:

Thank you all for help and invaluable knowledge !!! I sure learned a lot. It turns out, I stuck too much in the case WM_PAINT: , and that clogged the WM_TIMER messages. I rendered all my windows on WM_PAINT (DirectX stuff). Now, When I drag my windows some ungraceful visual effects happen, but I guess I'll manage.
