Nish [Signature temporarily down] unique timer id 6-Mar-02 20:16 6-Mar-02 20:16  how do you getting timer id what not conflicts with your window base class? i thought SetTimer() with duplicate id will return 0 but it is not true do you know any GetTimers(hwnd?) t! Re: unique timer id Nish Nishant6-Mar-02 20:30 Nish Nishant 6-Mar-02 20:30  The ID needs to be unique only within your CWnd class [assuming you are using this from an MFC CWnd derived class] In SDK each ID must be unique per HWND Nish [Signature temporarily down] Re: unique timer id 6-Mar-02 20:33 6-Mar-02 20:33  this i know but how to find there is (in that moment of course only) any already running timer with my id t! Re: unique timer id Nish Nishant6-Mar-02 20:35 Nish Nishant 6-Mar-02 20:35  Well, it's your program huh. Just use 100,200,300 etc. for your timer IDs. Its better not to have too many timers active at any one time. You dont have to worry about other timers in other programs. Nish [Signature temporarily down] Re: unique timer id 6-Mar-02 20:42 6-Mar-02 20:42  you always right but not replying to my question i want to get any error/assert when i'm starting already running id to use different value and i see no legal way what when your nr 100 uses your base class? (of course not necessary uses in that moment but that is another kind of problem, we can suppose in testing time i will find conflicts ignoring manual solutions like "use spy tool with filter to wm_timer") t! Re: unique timer id Nish Nishant6-Mar-02 20:54 Nish Nishant 6-Mar-02 20:54  As far as I see, the only strightforward way to achieve this, is to have an array of timerIDs, which is maintained manually. I dont see any other way to enumerate existing timers. Maybe there are other more advanced means available like global hooks, not sure though... Nish [Signature temporarily down] Re: unique timer id Tomasz Sowinski7-Mar-02 0:46 Tomasz Sowinski 7-Mar-02 0:46  No, there's no unique-within-the-class requirement. Just like SDK, it must be unique per CWnd.

That's what I meant when I said CWnd derived class, under the assumption that any particular CWnd derived class would hopefully not deal with more than one HWND Nish [Signature temporarily down] Re: unique timer id Tomasz Sowinski7-Mar-02 0:54 Tomasz Sowinski 7-Mar-02 0:54  That's what you wrote in first reply: Nish [BusterBoy] wrote: The ID needs to be unique only within your CWnd class [assuming you are using this from an MFC CWnd derived class] Class is not an object, and vice versa Tomasz Sowinski -- http://www.shooltz.com Re: unique timer id Nish Nishant7-Mar-02 1:05 Nish Nishant 7-Mar-02 1:05  Tomasz Sowinski wrote: Class is not an object, and vice versa The error is regretted I am sure glad you were not high school teacher.

In a CList<int,int> for instance or just an static int in the function you use for creating your timers... ------------------------------- Greetz, MG Re: unique timer id 7-Mar-02 2:46 7-Mar-02 2:46  no enought f.e. system conrols create their own timers do you know to say their ids are platform independent? t! Re: unique timer id MaxiGroovy7-Mar-02 2:55 MaxiGroovy 7-Mar-02 2:55  what do you mean by system controls? They are not in your program/Window so they don't bother you. ------------------------------- Greetz, MG Re: unique timer id 7-Mar-02 2:58 7-Mar-02 2:58  i have class derived from tree or list control and i want to create own timer there t! Re: unique timer id MaxiGroovy7-Mar-02 3:19 MaxiGroovy 7-Mar-02 3:19  so your tree or listcontrol will receive the timer message of the timers you create. and you can just create a timer like settimer(1,500,NULL); that's all. You think your tree control will receive timermessages from another control?? That's not true. If this is not your problem, please explain it to me/us. ------------------------------- Greetz, MG Re: unique timer id 7-Mar-02 3:17 7-Mar-02 3:17  if i in my tree class create own timer with id 42 it will fight with tree control created one (sure for w2000) - i can eat its timer event thinking its mine t! Re: unique timer id MaxiGroovy7-Mar-02 3:55 MaxiGroovy 7-Mar-02 3:55  I've never seen a simple tree control that uses timer events, unless I made them myself ------------------------------- Greetz, MG Re: unique timer id 7-Mar-02 23:52 7-Mar-02 23:52  i have in own program tree example with sending afer every l-click and example without it - can't get to search what is difference in tree properties can cause it the same timer ids are when spy-ing regedit or explorer (but here we can't be so sure it is system tree) any way - for simplicity try imagine you using not system control but another you have no sources t! Re: unique timer id 8-Mar-02 4:57 8-Mar-02 4:57  ok, it seems not-sending was because of my click handling not depended on control state do you realy have no WM_TIMER messages? t! Re: unique timer id MaxiGroovy8-Mar-02 4:58 MaxiGroovy 8-Mar-02 4:58  no, sorry. I realy don't know why a tree-control should use timer events, for what purpose? Is it just a tree-control or a ActiveX kind of tree-control? ------------------------------- Greetz, MG Re: unique timer id 8-Mar-02 5:09 8-Mar-02 5:09  tree control first example i recalled: when i l-click to last half visible item (maing it selected) it selects it and scrolls down after short delay (doubleclicktime) when you do it by keyboard it scrolls imediately t! Closing Document assertion? Richard Everingham6-Mar-02 19:11 Richard Everingham 6-Mar-02 19:11  Hello I am having a problem I don't understand. What I wanted was to have only one instance of a certain document open at once. So I overrided the On_File new of the app like this: void CEditorApp::OnFileNew() { // TODO: Add your command handler code here pMyTemplate->CloseAllDocuments(TRUE); CNewDSNDlg pDlg; pDlg.DoModal(); } Obviously this dosn't open a new document , the document in question is opened elsewhere. If there is not a document open it dosn't have a problem. If there is one, this throws an assertion for some reason. One thing that confuses me is it only throws the assertion when compiled in debug mode but not when compiled in release. The exemption it throws is in OBJCORE.CPP and is refered to as a User Breakpoint: // check to make sure the VTable pointer is valid ASSERT(sizeof(CObject) == sizeof(void*)); if (!AfxIsValidAddress(*(void**)pOb, sizeof(void*), FALSE)) { TRACE0("ASSERT_VALID fails with illegal vtable pointer.\n"); if (AfxAssertFailedLine(lpszFileName, nLine)) AfxDebugBreak(); return; // quick escape } Could someone explain why this assertion is only being thrown in debug and also wether or not I should even care? I am worried this will cause a memory leak or something. Thx, Richard
