• Visual C++ Detecting compile in Studio 2005 vs. Studio 2003 or 6.0

   I share common source code with several other projects that compile in Studio 2003, Studio 6.0, Borland, or (gasp) an embedded Green Hills compiler. Is there a #define I can look for so that I can fix all the deprecated CRT functions when I use the code in Studio 2005 (and so I can leave the old unchanged version in place for all the other folks) Something like #ifdef STUDIO_2005     strcpy_s(DestString, sizeof(DestString), SourceString);     errno_t err = fopen_s(&fp, Filename, "r"); #else // for older compilers     strcpy_s(DestString, sizeof(DestString), SourceString);   &n ...Show All

• Software Development for Windows Vista SetConsoleCtrlHandler() in Vista

  Hi, I have a win32 console tool compiled in VC2003 that I'm running on Vista 5356. The app calls SetConsoleCtrlHandler() and the handling function watches for CTRL_LOGOFF_EVENT or CTRL_SHUTDOWN_EVENT to trigger in order to write out some state information when a reboot occurs. This method worked fine in XPSP2 and Vista 5308. Now, in 5356, the handler never even gets triggered on a reboot. Neither CreateEvent() or SetConsoleCtrlHandler() return any errors. Also, the tool wont even run unless i launch it from a command prompt that was itself launched using right click->Run as Administrator. This was expected, however. Any h ...Show All

• Software Development for Windows Vista Need help using CompositeActivityDesigner

  I have a custom CompositeActivity with a custom CompositeActivityDesigner. I'm placing this activity inside a custom root activity, that uses a FreeFormActivityDesigner. The trouble is that the activity designer won't allow drag and drop another activity into it. I overrode CanInsertActivities and can say that it is not being called. (Also, CanInsertActivities is not called on the FreeFormActivityDesigner, either, but it does allow dropping an activity into it - any activity...) I must be missing something, does anyone have an idea what it might be I figured it out a solution, posting it for o ...Show All

• Smart Device Development CCommandbar with cmenu

  I try to insert a menu to ccommandbar, then delete a submenu in it. Is there any example on ccommandbar with cmenu m_cmdbar = new CCommandBar(); m_cmdbar->Create( this ); m_cmdbar->InsertMenuBar(IDR_MENU1); HMENU hMenu = m_cmdbar->GetMenu(); CMenu* pMenu = CMenu::FromHandle(hMenu); CMenu* submenu = pMenu->GetSubMenu(0); BOOL i = submenu->DeleteMenu(ID_OPTION_NEW, MF_BYCOMMAND); m_cmdbar->DrawMenuBar(IDR_MENU1); my above code does not hide the "new" menu, although I got the boolean i return as TRUE. So I suspect the problem is on the last line, which I don't know what to put in the ...Show All

• .NET Development TableRow Array object reference not set to an instance of an object

  I have a TableRow array that Im trying to store rows I add to a table later, But when I try to add Cells to each row on the first " trows [ i ] . Cells.Add(tcell); " line I get error stating 'Object reference not set to an instance of an object'. Based on the code I had before where I just had a single table row that is initialized new each time in the loop I think that might be why Im getting the error. But how can I get this to work so I can have an array of rows that I add to a table in a differnt part of the code TableRow [] trows; while (rdr.Read()) { for ( int i = 0; i <= 29; i++) { ...Show All

• Visual C# Threaded Controls

  I'm a little confused on how to show a progressBar with style continious on a seperate thread. Do I need to create the progressBar at runtime...or can I pop one on the form and just invoke it Style Continious can just be set in properties...with nothing really to do in the threadproc...know what I mean My form is also getting very "crowded"....mucho hidden panels groupbox, etc. Rather create at runtime and just bringtofront....let it run...and then abort when finished.

• Visual C++ Function pointers and delegates

  I'm trying to build a managed wrapper in C++/CLI for an existing static library written in C. I have a class where a few callbacks are needed. In the static library you have a function called "set" which registers the callback. However I'm strugling with some managed vs. unmanaged type problems. Lets say you have a callback with the following prototype: void f1proc(char *szString, int nSomeOtherData); Since I want to use String ^ instead of char * in the managed class I think I need to do the following: 1. Create a function with above prototype in my wrapper class. 2. Expose another function (as a delegate) which has similar prototype but us ...Show All
