Maybe you could try it quickly, insert a tree, associate with a variable, insert a button, copy paste my code in the event handler and see what the tree looks like.

Re: CTreeCtrl and deleting items Anand Paranjpe3-Oct-03 0:29 Anand Paranjpe 3-Oct-03 0:29  Hi, I have tested code as below and it works fine HTREEITEM hMyItem = m_myTree.InsertItem( "my item" ); HTREEITEM hMyChildItem = m_myTree.InsertItem( "my child item", hMyItem ); // 1. I delete the items I just inserted //-- m_myTree.DeleteAllItems(); // OR 2. (according to the MSDN that should do the same) //-- m_myTree.DeleteItem( TVI_ROOT ); hMyItem = m_myTree.InsertItem( "my item" ); hMyChildItem = m_myTree.InsertItem( "my child item", hMyItem ); Have u checked required properties of CTreeCtrl. I don't see any problem in your code. The chosen One Re: CTreeCtrl and deleting items vprat3-Oct-03 1:28 vprat 3-Oct-03 1:28  Just made a test ... works with Visual Studio 6 on another machine. Does not work on my machine with Visual Studio 2003 ! Same procedure, new MFC app with the wizards, insert a new tab control in the dialog, add a simple button, implement the event handler of the button to do: InsertItem; DeleteAllItems; InsertItem; Glups. Does anybody have the same problem or does this just come from the piece of s**t behind my keyboard ? How to stop other Process use ReadProcessMemory to Inject into my Process?don't use APIHOOK? runner1112-Oct-03 22:27 runner111 2-Oct-03 22:27  How to stop other Process use ReadProcessMemory to Inject into my Process?don't use APIHOOK? Re: How to stop other Process use ReadProcessMemory to Inject into my Process?don't use APIHOOK? Dominik Reichl2-Oct-03 22:47 Dominik Reichl 2-Oct-03 22:47  The only way is hooking the ReadProcessMemory system-widely and checking if a process wants to read from your process. You could also patch the ReadProcessMemory function (patch on assembler level to immediately return), but I wouldn't do it. Patching can lead to serious problems. This would require that you need to overwrite the Windows kernels of the users, and I don't think that most users like it if their kernel is patched... Dominik _outp(0x64, 0xAD); and __asm mov al, 0xAD __asm out 0x64, al do the same... but what do they do??

David Crow3-Oct-03 3:37 David Crow 3-Oct-03 3:37  I've not tried this so it's simply a guess. ReadProcessMemory() requires that the memory being read be accessible for read access. Otherwise, the function fails. That implies that your process could somehow "lock" its heap memory. Five birds are sitting on a fence. Three of them decide to fly off. How many are left? MFC popup menus and filedialog don't show in fullscreen Anonymous2-Oct-03 22:18 Anonymous 2-Oct-03 22:18  Hello all, I am using context menu (with TrackPopupMenu()). When I use it with an usual window, all is OK. If I use it in a "real" fullscreen window, it appears only now and then. I used SetForeGround(motherWindow) before, and postmessage (WM_NULL, ...) after and I still get a variable behavior. here is the code: SetForegroundWindow(myHwnd); int result = TrackPopupMenuEx(myMenu,TPM_RETURNCMD|TPM_TOPALIGN|TPM_LEFTALIGN|TPM_RIGHTBUTTON , pt.x, pt.y, myHwnd, NULL); PostMessage(myHwnd, WM_NULL, 0, 0); I also use fileDialog the same way (with setforeground and postmessage), which does not appear when called . I managed to get focused on it, but it takes my window out of fullscreen mode. fullscreen window is a DX or openGL render space. Hope someone will be able to help me ? Thanks in advance What's the difference between bool and BOOL? Link26002-Oct-03 21:27 Link2600 2-Oct-03 21:27  I only know that bool is a boolean type that only return true(1) or false(0). Then what about BOOL? I know they are different, but I don't know how they are different. Re: What's the difference between bool and BOOL?

Use bool as much as possible if u r not dealing with windows api. while porting OS from 16 bit to 32 bit, sizeof "BOOL"( which is typedef of integer) also increased.If in future, while porting OS to 128 bit, size of BOOL(same as sizeof int) will b 16 bytes. R u going to tolerate this stupidity if u r not dealing with WinAPI? If u r using more than one boolean variable in ur code, I 'll suggest u to use one bool with bitfields. This way u will accommodate upto 8 bool variables. I believe that MS Access stores boolean datatypes this way. The chosen One Does VS.Net support pure C language? Link26002-Oct-03 21:10 Link2600 2-Oct-03 21:10  Well, I wonder if VS.Net support pure C language? Since there is no C file that you can create when you open a new project in VS.Net. Re: Does VS.Net support pure C language? Rickard Andersson202-Oct-03 21:17 Rickard Andersson20 2-Oct-03 21:17  Yes it does.

Link26002-Oct-03 21:30 Link2600 2-Oct-03 21:30  By saying Pure C language, I mean C99, the latest ANSI/ISO standard for C. Have you written a project that using only C, and does not contain any code that is C++ stardand? And how is the result? Is the result what you expected? Any strange error during compiling and running? Re: Does VS.Net support pure C language? Rickard Andersson202-Oct-03 21:39 Rickard Andersson20 2-Oct-03 21:39  I've written an app i pure C yes. I discovered that the declarations of varibles couldn't be done anywhere in the code and has to be declared in the beginning of the scope. I've read in my "C: The Complete Reference" that C99 supports declarations anywhere in the code. http://duden.mine.nu/wr/Client/ That's the project I've made.

Link26002-Oct-03 22:27 Link2600 2-Oct-03 22:27  Well, I have just read your project. I have a question reguarding to that. In C++, it support OOP, so it is logically right to split files. Header being class definition, and cpp being implementation and driver. However, C does not do OOP, so how do they split files? What do they put in header file? Is it common to put everyting in a .c file? Well, you did that for your WZ project. P.S. I'm learning C++, but completely new to pure C. Thanks Re: Does VS.Net support pure C language? Rickard Andersson202-Oct-03 22:34 Rickard Andersson20 2-Oct-03 22:34  Yeah I did put everything in one .c file because it was just a test project and it had only a few hundreds lines of code. But yes, you do the same as in C++, put all your function declarations in one header file and globals and #defines and whatever you want and then implement it in your source file (.c or cpp).

Mike Dimmick2-Oct-03 22:56 Mike Dimmick 2-Oct-03 22:56  At the moment, very few compilers support C99 - it's too new. I believe that Microsoft is not intending to ever support C99 - they will only support C89 (as revised in 1995). C99 adds a few features that frankly are only of use in building larger scale programs, and for that, there's C++. IIRC, VC.NET (the environment) adds the /TP switch to your project settings, meaning that all files are compiled as C++ even if they have a .c extension. Turn this switch off if you want .c files compiled as C.
