stopping a process started with _beginthread LukeV29-Nov-02 7:34 LukeV 29-Nov-02 7:34  Does anyone has an example on how to cancel a process? Like when the user press the Cancel button. I tried _endthread() but I get 1st chance exception errors... What is the proper way? Thanks! Re: stopping a process started with _beginthread LukeV29-Nov-02 7:45 LukeV 29-Nov-02 7:45  I just used return; in the thread function and it seems to work... is this the proper way to do it? Re: stopping a process started with _beginthread Joao Vaz29-Nov-02 7:49 Joao Vaz 29-Nov-02 7:49  _beginthread begins a thread of execution, not a process, second, it's evil, dump it and use _beginthreadex that have a appropriate Thread Information block(TIB) to properly clean the resources consumed by the thread. Similarly the _endthread should not be used , use _endthreadex ... but it shouldn't use this either , the threads should exit for themselfs . You should create a event or binary semaphore (depending of what you want to achieve) and signal it to the thread that you want to cancel,then on the target thread that is expecting on a WaitforMultipleObjects(or similar), you catch the signed event(action) , clean up the resources , if you need to, and do a exit command(return ...) or exit simply by failling over the WaitFor ... loop ..

RobJones29-Nov-02 7:09 RobJones 29-Nov-02 7:09  Hello, I am trying to pull the text from a tool tip and put it into a CString.. The event fires but all I see in Debug mode is.. name = name = name = Any suggestions? void CMyTreeView::OnTvnGetInfoTip(NMHDR *pNMHDR, LRESULT *pResult) { LPNMTVGETINFOTIP pGetInfoTip = (LPNMTVGETINFOTIP)pNMHDR; CString strTip = pGetInfoTip->pszText; TRACE("name = %s\n",strTip); *pResult = 0; } Never mind..

It is requesting the tool tip information from you. Not the other way around. Tim Smith I'm going to patent thought. I have yet to see any prior art. Re: CTreeView quick question..

Maximilien29-Nov-02 5:58 Maximilien 29-Nov-02 5:58  Still on the freakishly devilish CControlBars problem ... I'm knee deep in MFC code right now, CDockContext , and I'd like to be able to trace CDockContext::CanDock, since it's called rather frequently, when moving a floating controlbar, I'd like to be able to find a way to trace it. Same thing for CFrameWnd::CanDock ( winfram2.cpp ) ... I'd like to ba able to tell the debugger, well, don't stop at this breakpoint, but just tell me that it should be triggered ... Any Idea ? Max.

And this database has to be updated from an internet adress. The question is. Could you propose me the way to do this automatically? In other words There is a way to download a file from internet and substitute the actual database in the application directory? Sorry if this questio looks silly to you, but I don't know how to do it, because I don't know how detect if the file download has benn completed. Best regards Doctor Pi Re: Update appication l a u r e n29-Nov-02 5:55 l a u r e n 29-Nov-02 5:55  first if u using a db like sql server u cant just dnload files cos it doesnt work that way ... to detect if a file has dnloaded correctly u can put a checksum in it and verify that on receipt of the file ... to update the db (assuming u mean data) send a file in a format ur comfy with and use that to update the data from ... if ur changing the schema or stored procs etc use a file containing the sql queries to do the update hope this helps "traffic lights are for people who can't make their own decisions" biz stuff   about me New Windows NickOne29-Nov-02 4:52 NickOne 29-Nov-02 4:52  Hello all, I have a question concerning opening new windows. Currently, I have a MDI project that does not have doc/view support. It opens bitmaps. When I open a bitmap, it opens it to the main window. When I click File->New a new window appears. These features are great, yet I can't seem to combine them. I'd liek the bitmap to open into a new window. I can open bitmaps over and over and over again, but it always just replaces the current one. How can I get the bitmap to open into a new window? Any ideas anyone? Like the code for File->New CMainFrame* pFrame = STATIC_DOWNCAST(CMainFrame, m_pMainWnd); // create a new MDI child window pFrame->CreateNewChild( RUNTIME_CLASS(CChildFrame), IDR_NICKMITYPE, m_hMDIMenu, m_hMDIAccel); How can I get this new window to open the bitmap into it, and not the background? Thanks, Nick Hughes Insure++, PurifyPlus berndg29-Nov-02 3:39 berndg 29-Nov-02 3:39  I am currently evaluating Insure++ and PurifyPlus/Windows.

As they configure and add a new point I use a static control to display an example point on the point-configuration dialog box. The problem I'm having is that even though I am using the same size to display the point on the dialog and to the view, the point in the dialog is half the size of the point on the view. I'm pretty sure this has to do with a difference in the point density of the DC I get to the static control and the DC I get to the view, but am not too sure where to start looking for a solution to this problem. Please could anyone offer some advice? well hell doesn't want you and heaven is full.
