Re: Small Challenge for all you experts Ravi Bhavnani14-Jun-04 1:26 Ravi Bhavnani 14-Jun-04 1:26  Would CBN_SELCHANGE help? That notifies you when the active selection in the dropdown list changes. You get another notification (CBN_SELENDOK or CBN_SELENDCANCEL, depending on whether the user made a selection or pressed Esc) when the listbox closes. /ravi My new year's resolution: 2048 x 1536 Home | Articles | Freeware | Music ravib@ravib.com Re: Small Challenge for all you experts bikram singh14-Jun-04 2:54 bikram singh 14-Jun-04 2:54  That doesnt work either The only notification I'm getting on the dropped-down listbox is WM_CTLCOLORLISTBOX, which I get each time I do a mouse-over on an item. Nothing else! I can "capture" a right-click on an item, using GetKeyState(VK_RBUTTON), but that only works bcos I change the item-selection while keeping the R button pressed, which causes a WM_CTLCOLORLISTBOX message , in which I call GetKeyState() as above. But this isnt a solution for me! Spy++ shows no messages except WM_CTLCOLORLISTBOX And thank you for helping out ! Bikram Singh Done it ! bikram singh14-Jun-04 3:01 bikram singh 14-Jun-04 3:01  Ultimately, I had to subclass the combobox' listbox. Was wanting to avoid doing it though. But well, if you cant fight em join em i guess! Bikram Singh how to add menu on dialog? vividtang13-Jun-04 1:19 vividtang 13-Jun-04 1:19  hi: all my program is based on dialog,but i want to add menu for it, i insert a menu resource and with the instruction of classwizard select associate the menu with my dialog,but when i do this ,once runing i found no menu on dialog,why , please lend me a hand. thx Re: how to add menu on dialog? bikram singh13-Jun-04 1:33 bikram singh 13-Jun-04 1:33  would have loved to answer, but i dont care to experiment with MFC. MFC sucks big time. Stop using it dude! Give C++ Builder a try, and you'll never come back to VC++ for any of your UI-related tasks. Infact, the only reason VC++ is good is: fast "code-completion". Thats it. From a programmers perspective. Bikram Singh Re: how to add menu on dialog? toxcct13-Jun-04 3:05 toxcct 13-Jun-04 3:05  hey, who do you think you are ??? if you don't like visual C++, don't use it... and don't register to codeproject either... moreover, vividtang was asking about adding a menu into a dialog, and your answer don't have any reason to be here... poor boy you are TOXCCT >>> GEII power Re: how to add menu on dialog? toxcct13-Jun-04 3:02 toxcct 13-Jun-04 3:02  rigth click onto your dialog and select properties in the context menu. there, you have a property called menu. select the menu you just created (and saved with an explicit name) in the associated combobox... there you dialog have its menu... TOXCCT >>> GEII power Re: how to add menu on dialog? Johan Rosengren13-Jun-04 3:07 Johan Rosengren 13-Jun-04 3:07  You'll have to associate the resources, if you have not already done that. In MSVC++, you select the dialog box properties in the resource editor, and select the menu from the dropdown Menu. Note that you will not be able to see the menu in the resource editor - it only shows when running the program. A window never get focus? uniqueworld13-Jun-04 0:51 uniqueworld 13-Jun-04 0:51  How can I make my app not get focus like On-Screen keyboard in XP. I try to use WM_MOUSEACTIVATE with return value MA_NOACTIVATE but I can't.When I click button in my dialog,it activates.So i can't send key events to other applications(I use SendInput). Please help me. Re: A window never get focus? bikram singh13-Jun-04 1:31 bikram singh 13-Jun-04 1:31  Information not enough for a good answer. 1. Use EnableWindow(hwnd,FALSE) to disable any mouse or kbd input to the window. This is the only suggestion as of now... Bikram Singh Re: A window never get focus? toxcct13-Jun-04 3:08 toxcct 13-Jun-04 3:08  if you want the focus to bet set at the creation of your dialog, call Cwnd::SetFocus() into OnInitDialog() and make this function return TRUE. if you just need to set the focus on a control when doing someting into the dialog, just call SetFocus(). TOXCCT >>> GEII power Re: A window never get focus? Behzad Ebrahimi13-Jun-04 4:24 Behzad Ebrahimi 13-Jun-04 4:24  I think that you must call SetFocus in WM_SETFOCUS and pass its lparam to SetFocus! Is that right? Re: A window never get focus? toxcct13-Jun-04 4:27 toxcct 13-Jun-04 4:27  WM_SETFOCUS is a message, not a function. moreover, you can call SetFocus() anywhere (in a handler you created for example) TOXCCT >>> GEII power Re: A window never get focus? Behzad Ebrahimi13-Jun-04 4:38 Behzad Ebrahimi 13-Jun-04 4:38  It is right, WM_SETFOCUS is a message. When a window receive this message, it can reject its focus by calling SetFocus! gif format includeh1012-Jun-04 22:50 includeh10 12-Jun-04 22:50  i need c++ source code (library) to covert bitmap file to gif file, the code is in c or c++ style, not COM or ActiveX. thanks for any link cheers includeh10 Re: gif format Johan Rosengren12-Jun-04 23:38 Johan Rosengren 12-Jun-04 23:38  http://www.codeproject.com/bitmap/CXImage.asp[^] Note the licence exceptions. Urgent Requirement-Socket Programming Billar12-Jun-04 19:18 Billar 12-Jun-04 19:18  Dear Friends, I am using CAsyncSocket and CSocket for writting a server program. In AsyncSocket I am using virtual void OnAccept(int nErrorCode); virtual void OnClose(int nErrorCode); virtual void OnReceive(int nErrorCode); and also in Socket I am using virtual void OnAccept(int nErrorCode); virtual void OnClose(int nErrorCode); virtual void OnConnect(int nErrorCode); virtual void OnReceive(int nErrorCode); Also in the dlg.cpp file, At InitDialog I am writting m_cSocketServer.Create(4000); m_cSocketServer.Listen(); m_cAsyncSocketServer.Create(4000); m_cSocketServer.Listen(); Also at the Onbutton message I am checking and writting a message into a display like this void CMFCServerDlg::OnButtonConnection() { // TODO: この位置にコントロール通知ハンドラ用のコードを追加してください char DispBuf[256]; if(m_cSocketServer.Create(4000) && m_cSocketServer.Listen()){ sprintf(DispBuf, "Server Started"); AfxGetMainWnd()->GetDlgItem(IDC_STATIC)->SetWindowText(DispBuf); } else{ sprintf(DispBuf, "Connection Failed"); AfxGetMainWnd()->GetDlgItem(IDC_STATIC)->SetWindowText(DispBuf); } For other reference.... LRESULT CMFCServerDlg::OnAccept(WPARAM wParam, LPARAM lParam) { m_cSocketServer.Accept(m_cAsyncSocketServer); DestroyFlag = TRUE; return 0; } This is a user message send by the AsyncSocket and Socket from OnAcceptMessage.... My applicaion is very simple and with the above code it is not working. Will you please help to detect the error. Why this code is not suitable to develop a simple server. Here, I have a dialog box with one button and a text box. Button is for to start a server and text box is nothing but to display a message that server is started. Please help me to find out the solution. Thanking You in advance. Billar Re: Urgent Requirement-Socket Programming includeh1012-Jun-04 22:59 includeh10 12-Jun-04 22:59  there are few samples in MSDN (VC CD), you can learn from those samples, they are not complex. cheers includeh10 Re: Urgent Requirement-Socket Programming Billar12-Jun-04 23:29 Billar 12-Jun-04 23:29  Hi includeh10 I don't have msdn. So if you can provide the such samples, it will be a great help to me. Waiting for your reply.......

Actually the problem was at the client side. I was not initializing the socket at the client side at InitInstance. But now it is solved. Thank you once again for everything. Bye Billar Drawing on empty space in MDI app brdavid12-Jun-04 12:56 brdavid 12-Jun-04 12:56  when you first run a MDI app you have the empty space, the dark gray background. I'm wondering if it's possible to draw in that space. For example is it possible to paint it white and place text, perhaps a bitmap, or just paint it white period. thanks! Re: Drawing on empty space in MDI app Joel Lucsy12-Jun-04 14:08 Joel Lucsy 12-Jun-04 14:08  Yep, sure can. The MainFrame (or CMDIFrameWnd) will have a m_wndClientArea variable. From that you can either subclass that window and do what you want, or create a sub-control to place onto it. I used the sub-control method to create a "start page" that had a MRU list and stuff that really wasn't a document. -- Joel Lucsy
