Hi All, I am currently interested in finding how firewall (in Windows) works. I could find information regarding packet filtering, but I am wondering how to directly blocked/denied a program (let's say IE @_@) to access to internet since I can find such functionality on existing firewall application (e.g. Windows defender firewall/ZoneAlarm). Would you help to provide some information regarding this? (Website/document/reference) Thanks! Yours, Vincent

Hi Mark, Thanks for your reply ^^ err... what I wrote right now is exactly same as yours... (even the file name ) however, the outcome is just a dark background but not transparent... Maybe I put at a wrong message call location? I put the above code under OnEraseBackground() Vincent

I called it at OnEraseBackground() I would like to have a transparent background (i.e. I set the desktop background to black/white, I hope the image boundary will be "blur" with the work of alpha bending). I am not sure if what I do is right, however, with using the Graphics::SetCompositingMode(), it seems that the Graphics::DrawImage() method will not directly apply the alpha bending information? ( I use Bitmap::GetPixelFormat() to verify the input image is a PixelFormat32bppARGB type, which means it should include the alpha channel)

Hi All, I am writing an application which try to show PNG file as a dialog background using GDI+ I have successfully using the PNG as background (using Graphics::DrawImage()), however, I found that the loaded PNG seems not apply the alpha channel information. What I should do? Thanks! (sorry for repeat posting if there is any) Vincent

Hi All, currently i am developing an application for audio playback, including local and online resources. I planned to use WMP SDK to help, however, one of my function needs me to be able to select/change the default audio device, however, it is not support by the SDK. I would like to know is there any other method to do so? (just like Skype/WMP itself hae similar function) thanks a lot~ :)

Hi All, Recently I tried to write a little player with the help of WMP10 SDK. To start with, I read the information provided from MSDN and try to follow the steps provide. Using the Windows Media Player Control in a C++ Program All things work well until to the section of non-wrapper class, I find that when I copy and paste the code provided to have a test error reported....:sigh: would anyone mind to advise me on what I have missed? (For the wrapper class there is no problem ...) Really thanks!;)

hmm.... those thread are worker thread or UI thread? :doh:

there is a problem assume your OnKeyFunction1 at parent (CMainWindow::OnKeyFunction1()) is for closing the application, in it you will KILL the child (i.e. delete the pointer of child window or equivlant) and so the function don't know how to return to the child part (CChildWindow::OnKeyFunction1)!! so, what you have to do is change the structure: 1. Use callback function to use parent window function instead of directly calling, callback allow window to handle when to call the function 2. Use Send message as the "tunnel" for commuincation for some command function 3. try to build the function in child only if it only consider to be used in child hope this help!

I assume what you have done is as follow: // in Main dialog (CMainDlg), // Contain a member variable pointer of CChildDlg, so call dChildDlg // At OnInitDialog() of CMainDlg { /* Something */ dChildDlg = new CChildDlg; dChildDlg->Create(/*some param.*/); /* Something */ }; If the case is similar, maybe you check if you call : delete dChildDlg somewhere before you call: dChildDlg->DestroyWindow() Hope this help a bit~ -- modified at 4:35 Friday 6th January, 2006

How you create the child window? :^) In addition, have you trace in debug window line by line to see at which line the problem occur? ;)

Instead of using PostMessage function, I use SendMessage with the message as "WM_SYSCOMMAND" here is the example: ::SendMessage(pParent->m_hWnd,WM_SYSCOMMAND,SC_CLOSE,0); I guess the assertion error may be related to your child window? You should better have a look what you have done on Destroying child window, especially pointers stuff ..... :(( Hope this help
