Re: Setting menu item as checked Jay Hova24-Jul-03 7:43 Jay Hova 24-Jul-03 7:43  Hi, I don't want to disable the window, i just want the menu item to be unchecked whenever the window is closed. I got it to be checked, just can't get it unchecked. I searched but didn't find what i was looking for. thanks for the suggestion. Any more help would be appreciated.

This is what pCmdUI->SetCheck( DisplayedWindow == NULL ) does (actually it should be DisplayedWindow != NULL). When you close your window have a pointer that refers to that window and set it to NULL. DisplayedWindow supposedly is a pointer that you should declare and initialized when you create the window and destory it when you close the window. In my code if DisplayedWindow != NULL evaluates to true then the menu item will be checked, otherwise it will be unchecked.

Now the new dialogs will control that menu item in it's parent. void MyClass::checkmymenuitem(int checked) { CMenu* pMainMenu = GetParent()->GetMenu(); CMenu *submenu = pMainMenu->GetSubMenu(1); // replace 1 by the horizontal menu position UINT g = submenu->GetMenuItemID(3); // replace 3 by the actual vertical item position CString mnustr; submenu->GetMenuString(3, mnustr, MF_BYPOSITION); // replace 3 by the actual vertical item position // you can optionally change mnustr to a text here if (checked) submenu->ModifyMenu(3, MF_BYPOSITION | MF_STRING | MF_CHECKED, g, mnustr); else submenu->ModifyMenu(3, MF_BYPOSITION | MF_STRING | MF_UNCHECKED, g, mnustr); } in initdialog checkmymenuitem(true); then in onclose checkmymenuitem(false); Re: Setting menu item as checked Jay Hova25-Jul-03 1:54 Jay Hova 25-Jul-03 1:54  Beer26, This is what i want...but I still have a problem. I put in the code that you gave me and it works fine at start up and the first time that the menu item is selected. But if i close the window and the select the menu item again, it doesn't update with a check mark the second time. Am i doing something wrong or is there something else that needs to be done? Thanks for the help btw, i really appreciate it Re: Setting menu item as checked Beer2625-Jul-03 2:47 Beer26 25-Jul-03 2:47  "it doesn't update with a check mark the second time." It should, you could make sure that the 2nd windows's parent is the window with the menu, and you could put some code in there to make sure the pointers aren't NULL; software and security Cyberizen24-Jul-03 5:53 Cyberizen 24-Jul-03 5:53  hello people my question is how do i make my software secure that is i have this application which i want the users to use for it a limited after which they must have a license how i do write code so that the application expires in a particualar time i heard that softwares that expire with time write something on the registry so dont you think anyone can just open up the registry and edit the setting and make the software work forever so how to make it secure any methods anyhing would be appreciated and also after the user has acquired a license where do i keep the license information and all please help regards Ahmed Ajmal Re: software and security Alexander M.,24-Jul-03 6:47 Alexander M., 24-Jul-03 6:47  lol.... no comma, no full stop, complete chaos!

If you want to store data in the registry, encrypt it, and put in a location that is not obvious. // Afterall, I realized that even my comment lines have bugs When one cannot invent, one must at least improve (in bed).-My latest fortune cookie Re: software and security AlexO24-Jul-03 7:55 AlexO 24-Jul-03 7:55  Cyberizen wrote: anyone can just open up the registry and edit the setting Not anyone, very few people actually understand how to work with registry. Very, very, very few people are capable of hacking into binary encrypted data (assuming that you wright binary encrypted data into the registry). From my experience there is no such thing as absolutely secure system, however RC2 and other encryption algorithms are pretty close. Multiple Threads Dangleberry24-Jul-03 5:46 Dangleberry 24-Jul-03 5:46  Hi all, I have a dilemma involving message handling. Basically I'm writing a game and have created a frontend in its own thread. To avoid multithreaded render problems the application always calls the frontend when it is required to be rendered. However, I would like the frontend to track all the keyboard and mouse messages (not the app) when the frontend is active, but the app should process them when it is inactive (to move the character etc.). I have not yet implemented directinput (though I am using directx), though maybe it is about time I did. What I would like to know is how to have my frontend feeding on mouse and keyboard messages sent to the app when its active, and stop when its inactive. I had a look at SetWindowsHookEx but this only gets activated when the app uses PeekMessage and the whole purpose of having my frontend in another thread spying on mouse and keyboard messages was so that lengthy renders don't inhibit the mouse and keyboard events. Any ideas or advice would be appreciated in this respect. Many Thanks, Alan. Re: Multiple Threads John M. Drescher24-Jul-03 5:50 John M. Drescher 24-Jul-03 5:50  Use the keyboard and mouse hooks instead. John Re: Multiple Threads Anonymous24-Jul-03 6:26 Anonymous 24-Jul-03 6:26  You mean MouseProc (and KeyboardProc presumably)? Looking at this in MSDN it still waits for the app to peekmessage with a relevant message pending. I seem to be in a catch 22 where I want the frontend to handle message pumping when it is active and the app to handle it when it is not, I think a way of re-routing messages to a thread is perhaps what I need (so when the frontend is activated the messages are routed to that thread and when it is deactivated it is re-routed to the app thread). Not sure how to do this, or if its even worth it? What do ya reckon? Thanks for the info though Alan.

I am not sure that it does this however I have never used it in an app than did not have the default message pump... John Re: Multiple Threads Alexander M.,25-Jul-03 2:33 Alexander M., 25-Jul-03 2:33  i used the global keyboard hook for a winamp plugin Don't try it, just do it! Re: Multiple Threads Dangleberry25-Jul-03 3:52 Dangleberry 25-Jul-03 3:52  Cheers for your responses, I've read the MSDN SetWindowsHookEx article which hooks the thread/process to the peekmessage pump. However, it seems to be event driven so when the peekmessage function is called from the app, the hook gets activated and the thread can handle the message if it wants. I think what I need is a message pump in its own thread that diverts messages to the appropriate thread depending on the application status, I think this solution will be a bit neater than stealing an apps messages. What do you reckon? Alan.

Then calc the size of your 3/4 Window and set the new size for it with SetWindowPos(...).

Thanks, Deepak Samuel Re: How to get data from a retrieve data from a list box (activeX control) Michael P Butler24-Jul-03 6:42 Michael P Butler 24-Jul-03 6:42  Judging from the C++ generated wrapper class for this control, it probably isn't very easy to do or recommended. Is their a particular reason you want to use this control in a C++ project. Michael 'War is at best barbarism...Its glory is all moonshine.
