sorry ravi, it was a scoping issue but i am still not clear why. the CBitmap bmp; is required to be a class level member. I was assuming that when we call a setbitmap on the button and pass a HBITMAP to it, a copy should be sent and there should be no scoping issue.

setbitmap takes an object so i dont think that could be a reason. But may be its worth trying.

thats a subclass and thats what i dont wanna do. I also tried adding the style BS_BITMAP thru the setwindowlong just to makesure the style was being set but no luck.....

I am trying to add a bit map to a cbutton. In the resource editor i do set the bitmap property to true. On the init dialog this is what i have. CButton* pButton = (CButton*) GetDlgItem(BUTTON_ID); CBitmap bmp; bmp.LoadBitmap(BITMAP_ID); HBITMAP hBmp = HBITMAP(bmp); pButton->SetBitmap(hBmp); the bitmap doesnt appear any suggestions? What am i doing wrong??? Thanks in advance

I am trying to capture the event that happens on holding the stylus at a point on the screen i tried doing what i want to do in the handler of NM_RECOGNIZEGESTURE but that doesnt work. Any sugesstions.

got rid of the compilation error need to use ON_COMMAND_REFLECT_EX. So now my code compiles and runs but the handler of the parent is not invoked why?? although i do have an onButtonClick in the parent.

I am using message reflection in myButton class so what i have in the message map is as below: BEGIN_MESSAGE_MAP(myButton, CButton) ON_CONTROL_REFLECT(BN_CLICKED, onButtonClick) END_MESSAGE_MAP() the prototype for onButtonClick() is afx_msg void onButtonClick() and this works well. But i do want the parent as well to be notified so as mentioned in the MFC doc i modified the onButtonClick to return BOOL so it is then afx_msg BOOL onButtonClick() But this gives a compile time error : error C2440: 'static_cast' : cannot convert from 'BOOL (__thiscall aegis::myButton::* )(void)' to 'AFX_PMSG' None of the functions with this name in scope match the target type. Any suggestions or is it a yet another bug in mfc. thanks

hi, I want the list control to be able to have images in differnt columns( could be any column 0,1,2..) so i create a CIMAGELIST from some resource and also set it for the list control by calling the method m_listCtrl->SetImageList(&m_imagelistsmall, LVSIL_SMALL); What this does is set the images from the imagelist in column1( always). even when i dont specify the LVIF_IMAGE mask when adding item. I dont want the image in the first column. Also what do i do to have the image in other other columns

Hi, I have a dilaog box(parent) which has a tab control whose tabs are implemented as dialog boxes(children). Each tab has some controls say a button on tab1. I want to delegate the events cretaed by controls on various tabs to the parent dialog. How can i do that. Is there a macro just like reflection macros? we know that control events will be handled by their parent that is my child dialog instead i want them to passed down the hierarchy to the parent dialog. thanks

i am successfully able to create the tabcontrol using the cdialog extended class as tabs. what is the difference in "can do and cannot do" if a property sheet is used instead? Which of the two is better to use and why?

i want to dynamically create a tabctrl and add tabs dynamically to it. Also teh controls rendered on each tab will be dynamically created. Any suggestion of how it can be achieved.

i am overriding wndproc an handling the wm_command and wm_notify message appropriately. in the case statement of wm_notify this is what i have case WM_NOTIFY: nmhdr = (NMHDR*) lParam; notificationId = nmhdr->code; if(notificationId == NM_CLICK) { AfxMessageBox(_T("CLICKED")); return FALSE; } else if(notificationId == NM_DBLCLK) { AfxMessageBox(_T("double CLICKED")); return FALSE; } ... .... //more if else goes here else { // call default } the flow does enter this switch statement but never invokes the appropriate handler. When i tried to get the value of the notificationId it shows some junk value though nmhdr is properly initialzed and the controlid that generated the message is correct. what am i missing? thanks

I am trying to create some common controls on windows ce. This is what i am doing. m_tooltip= new CToolTipCtrl(); m_tooltip->Create(this); m_tooltip->AddTool(button1,"Test Button"); m_tooltip->Activate(TRUE); this is a code snippet from OnInitDialog(). Ihave included the headers afxcmn.h and commctrl.h but i still get the following compile time errors. Anything else i need to include error C2512: 'CToolTipCtrl' : no appropriate default constructor available error C2027: use of undefined type 'CToolTipCtrl'd:\Program Files\Windows CE Tools\wce420\STANDARDSDK_420\mfc\include\afxstat_.h(337) : see declaration of 'CToolTipCtrl' and more all related to the common controls. thanks,

thanks a lot. Your explanation solved it all. Is this behaviour of getMessage and pretranslate/translate message documented somewhere in msdn so that i could dig more into it.

Correct, but assume that the controls on the dialog are dynamically created such that at time of coding i dont know as to what are the controls on the dialog. So i cannot provide the macro ON_BN_CLIKCED(btnid, handler). The reason i want to over ride the pretranslatemessage is to catch what ever goes thru the message loop filter the messages i am intersted in by using and ifelse construct like you mentioned. But the main question is my handler in pretranslate never gets invoked Why??? Cmydialog::PreTranslateMessage(MSG *msg) { if( pMsg->message == WM_COMMAND ) { if(LOWORD(pMsg->wParam)==IDC_CTRL_ID && HIWORD(pMsg->wParam)==BN_CLICKED) { UINT controlID = LOWORD(pMsg->wParam); if (controlID == someidofinterest) { //do what i want it to do } } } }

I dont wanna go subclass way because i dont wanna subclass "n" classes. Since my ui may have n differnt controls.

i tried notify but no change. I cannot handle it still.

"You can process the message in the parent window. The only thing you have to do is map a message handler to the desired action in your windows message map: BEGIN_MESSAGE_MAPE(YourWindow, DerivedFrom) ON_BN_CLICKED(IDD_YOUR_BUTTON_ID, memberfxn) END_MESSAGE_MAP() " That is correct but my requirement is slightly different. I dont want to provide a static macro like the one above. Because my application reads what controls are to be rendered from datastructure. It reads from the datastructure that it need to create a button with xyz style , a textbox with some wdth and style etc. Now i cannot use static statemenst as above. So what i wanted to do was intercept the default message handling mechanism. I wanted to override the pretranslate message for this and then from the MSG structure get what was the event fired and who fired it process it in pretranslatemessage and return.

it could be a bn_clicked, en_change, cbn_selchanged any message( command or notification ). I donot agree that BN_CLIcKED is a wm_notify type because CButton is a standard control and not a common control.

thanks for the answer. But this is what i understand about the message handling mechanism of MFC. When a control say a button is clicked it invokes its own wndproc which does what ever is required( say showing it in depressed state). Thiis because every control is actually a window.And then it sends anotification to the parent WM_COMMAND( in this case with msg as BN_CLICKED). Right? If this was the case then i Should be able to handle BN_CLICKED in parent. Please correct me if i am wrong.
