I can include it in the first source file I create, I can add a form to the project and use it in the form code file, I can link these things together, etc. If I start a Net project I can add a generic C++ class and use <complex> therein, but any time I ntry to link this file to anything I get link errors. If I use <complex> in a form's code, or any other type of managed file, I get these same errors. I can copy code from another such project that I download, which works just fine, intop my own project, and it fails. These are typical. delete3 fatal error LNK1120: 2 unresolved externals delete3 error LNK2020: unresolved token (0A000016) delete delete3 error LNK2020: unresolved token (0A000006) _CxxThrowException Why?

You will get some linker errors. Remedy is you need to rebuild your static lib with VC.NET.

Maarten Kools28-Jun-04 7:04 Maarten Kools 28-Jun-04 7:04  Hi, I'm messing with some custom tooltips. Here's the situation: In my application I'm showing certain items in a list ctrl. There's a note column and a (jpeg) preview column. Both should display tooltips. My idea was to override a CToolTipCtrl and the WM_PAINT message for that control. Then in OnToolHitTest I would test whether the mouse is hovering over a note or preview and it would fill the members (a jpeg image or string, depending on what I'm pointing at) and use either of these in the WM_PAINT handler. Now, once I hovered over an existing note, the tooltip keeps displaying (I set it to trigger for the whole client rect), even though I keep returning -1 from OnToolHitTest. So I'm not really sure what I'm missing here, it does work for the first time though. But once a tooltip has been displayed, it's pretty much broken. perform action on close [X] button elephantstar28-Jun-04 6:58 elephantstar 28-Jun-04 6:58  Why is it that I can't get this window to call OnSysCommand when the user clicks on the Close [X] button. Is there something wrong with my code that someone can point out or am I leaving something out? Thanks! /*************************************/ CClass1.h class CClass1: public CFormView { ....code..... protected: // Generated message map functions //{{AFX_MSG(Class1) afx_msg void OnSysCommand(UINT nID,LPARAM lParam); //}}AFX_MSG DECLARE_MESSAGE_MAP() }; CClass1.cpp BEGIN_MESSAGE_MAP(CClass1, CFormView) //{{AFX_MSG_MAP(CClass1) ON_WM_SYSCOMMAND() //}}AFX_MSG_MAP END_MESSAGE_MAP() void CClass1::OnSysCommand(UINT nID, LPARAM lParam) { if(nID == SC_CLOSE) //Check If [X] Button { AfxMessageBox(_T("Hello")); } else CFormView::OnSysCommand(nID, lParam); } Re: perform action on close [X] button Neville Franks28-Jun-04 10:07 Neville Franks 28-Jun-04 10:07  From memory OnSysCommand() is called for items selected on the System Menu, not for the [x] Close button. Use WM_CLOSE (OnClose?) for that.

Anything else I'm missing? void CClass1::OnClose() { //perform actions before closing CFormView::OnClose(); } Re: perform action on close [X] button Neville Franks28-Jun-04 11:28 Neville Franks 28-Jun-04 11:28  I have seen this type of problem. If it is a Document.View app then look at CDocument::CanCloseFrame().

It doesn't seem to call the function when [X] is clicked just like OnClose. What I am doing wrong? BOOL CClass1::CanCloseFrame(CFrameWnd* pFrame) { ...more code... return TRUE; } Re: perform action on close [X] button Neville Franks28-Jun-04 12:31 Neville Franks 28-Jun-04 12:31  Is CClass1 your CDocument class? ie.

Re: perform action on close [X] button Neville Franks28-Jun-04 12:48 Neville Franks 28-Jun-04 12:48  And in your CClass1 it is virtual? ie. virtual BOOL CanCloseFrame(CFrameWnd* pFrame); Neville Franks, Author of ED for Windows www.getsoft.com and coming soon: Surfulater www.surfulater.com Re: perform action on close [X] button elephantstar28-Jun-04 13:13 elephantstar 28-Jun-04 13:13  Yes. Re: perform action on close [X] button Neville Franks28-Jun-04 13:20 Neville Franks 28-Jun-04 13:20  Time to hop into the Debugger and look at the code for the FrameWindow's OnClose() which calls this function. All should become clear then.

How does that work? Re: perform action on close [X] button Neville Franks28-Jun-04 14:57 Neville Franks 28-Jun-04 14:57  Look at the MFC Source code for CFrameWnd::OnClose(). ED tells me this is in WINFRM.CPP Neville Franks, Author of ED for Windows www.getsoft.com and coming soon: Surfulater www.surfulater.com Re: perform action on close [X] button elephantstar29-Jun-04 8:23 elephantstar 29-Jun-04 8:23  I created CanCloseFrame()in the document class. Within that function, how can I call the calling frame view's close function. For example, when I close CClass1 document view using [X], CanCloseFrame() from the document class is called. How do I know which frame or view called it so that I can call its corresponding OnClose function?

I don't think you can find this out. You need to go back and work out why the views OnClose() isn't being called. Again the MFC Source and VC++ Debugger are your friends here. Start by setting a breakpoint on CWnd::OnClose(), then CView::OnClose() etc. Neville Franks, Author of ED for Windows www.getsoft.com and coming soon: Surfulater www.surfulater.com Re: perform action on close [X] button elephantstar29-Jun-04 13:01 elephantstar 29-Jun-04 13:01  I have both OnSysCommand and CanCloseFrame but none of them work. When the window is closed, it calls CanCloseFrame, CFrameWnd::OnClose, and then CDocument::OnCloseDocument. I've been using the debugger but it's not helping at the moment. I'm back where I started.
