    - Enabling Memory Leak Detection Hi, I am trying to enable memory leak detection based on the url below. If I use _CRTDBG_MAP_ALLOC instead of CRTDBG_MAP_ALLOC in a test program, I can see the offending line numbers and source file get printed out. However in the program that I am trying to find memory leaks, I get the same debug output regardless of whether I #define _CRTDBG_MAP_ALLOC or CRTDBG_MAP_ALLOC. And I only get one line number <dllmodul.cpp(106)> output instead of every offending (leak causing) line number. Why is that? // based on http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vsdebug/html/vxconenablingmemoryleakdetection.asp #define _CRTDBG_MAP_ALLOC #include <stdlib.h> #include <crtdbg.h> . . . _CrtDumpMemoryLeaks(); OUTPUT Detected memory leaks!

    - Client Server using TCP/IP - which interface to use? Hi there... I want to write a small utility. It should be front- and backend running on different machines. I don't want to handle error correction or timeouts by myself. Communication is TCP/IP. How could I easyly do the communication? CSocket or something else.

    - GetDIBits is returning 0 hi, i'm geting de bits of to bitmaps into a buffer in order to compare then. the first time i call GetDIBits, it works ok, and returns the number of scanlines an correct data in the buffer. the second time, it returns 0 and does nothing in the baffer. if i change the order of the calls, the second still fails. i know that then bitmaps must not be selected on any DC, and i'm carefully with that. ¿¿any reason why GetDIBits returns 0?? Thank you. by MJM. Tag: Dll Entry Point Name Tag: 250338

    - reversing bit order Hi folks - I'm writing some code for a checksum algorithm and I need to reverse the order of bits in an unsigned char array, in 4-bit chunks (half byte, or nibble). Example.. the array contains BYTE data: 0001 0110, 0000 0010, 1000 0000 0x16, 0x02, 0x80 Each nibble gets reversed: 1000 0110, 0000 0100, 0001 0000 0x86, 0x04, 0x10 Each nibble will then be added and the results become a checksum nibble. I can do this brute force, one bit at a time, but I'm hoping someone out there will recognize a possible elegant solution. There will always be 5 bytes (40 bits, 10 nibbles) to deal with. Any ideas? Thanks. Tag: Dll Entry Point Name Tag: 250334

    - Tree control: How do I get the expand / collapse icons? I'm performing a custom draw of the items of a tree control and I need to be able to draw the expand and collapse toggle button ([+] & [-]) that appears to the left of items with children. I need to know how to get that icon, and the coordinates that the OS expects the symbol to be drawn. I can't find this information in the MSDN.

    - Initializing member variables Hi, I did this test using VC .NET 7.0: #include <iostream> using namespace std; class A { public: //A () { } // Providing a default constructor makes it work int i; int GetI() { return i; } }; int main(int argc, char* argv[]) { A a; //cout << a.GetI() << endl; //This call works cout << a.i << endl; //Throws Runtime error a.i++; //Throws Runtime Error return 0; } In the lines mentioned, it throws a runtime error saying that the variable is not 'defined'. The variable is not initialized, of course, but what makes it not throw the error if: 1) the default constructor is provided, which does not actually initialize 'i'? 2) a.GetI() is called, again without initializing 'i'?

    - Using WebBrowser Control, how to Navigate w/o displaying the HTML page. I built an MFC project of the SDI type, hosting a WebBrowser Control. Everything seems to behave properly. I am using the Navigate(LPCTSTR URL) to get web pages. Is it possible and if so how to perform all the functionality of the Navigate() w/o display the page? There is a method called SetVisible(false/true) but when trying to use it, it creates an exception. With and w/o regard to the above question, Is it preferred to have a host of the MDI (or top level MDI) type, as to separate between the host's GUI window and the window in which the WebBrowser Control displays a page (that is if I allow it to do that)? Thanks, David Tag: Dll Entry Point Name Tag: 250301

    - std::_MAX Replacement I'm migrating from VS6.0 to VS 2003 .Net. One of the breaking changes is that _MAX has been redefined so that std::_MAX will no longer compile. I tried changing each usage to std::max, but that won't compile either. So I went using std::max ... float a = max(b, c); which is compiling. How have other people dealt with this issue? Thanks in advance! Tag: Dll Entry Point Name Tag: 250291

    - Lost on anything pertaining to MessageBox I have the following 2 files: File1.cpp Line 100: MessageBox("ABC"); Line 101: MessageBox(NULL,"ABC",NULL,MB_OK); File2.cpp Line 120: MessageBox("ABC"); Line 121: MessageBox(NULL,"ABC",NULL,MB_OK); When compiling, I am getting two error messages: File1.cpp(100): error C2660: 'CWnd::MessageBoxA' : function does not take 4 arguments File2.cpp(121): error C2660: 'MessageBoxA' : function does not take 1 arguments So it does not like one MessageBox signature in one file and likes the other one While in the other file it is the reverse! #include statement in both files are identical. Couldn't find a clear decription of the usage of MessageBox. I guess it must be related to the base classes of the involved derived classes in each file: class File1_X : public Cdocument class File2_X : public ChtmlView Anybody saw a good & COMPLETE definition of MessageBox?

    - simple dll question How can you register a VC++6 dll which won't register with regserv32? This project was made with MFC App Wizard(dll). The project works fine when it's placed in Windows\System32\ for Visual Basic 6, but I need to place it somewhere else. Thank you. -- Rick Tag: Dll Entry Point Name Tag: 250165

    - VC 8 crash (fatal internal error) when using nested exceptions Greetings, While migrating some old code (5+ years) to VC 8, Beta 2 (for targeting AMD64), I encountered an internal compiler error when building release builds. This code builds fine in both VC 6 & 7.1 when targeting x86 (I think it even built fine in VC 4.2 if my memory squeeks correctly). The code in question has nested try/except blocks, for example: " __try { //OS Call } __except( EXCEPTION_EXECUTE_HANDLER ) { __try { //OS_call(different parameters) } __except( EXCEPTION_EXECUTE_HANDLER ) { //review parameters, cleanup, unwind } } " This crash was easily worked around by moving the nested exception block to its own function. Here are the juicy details from a cross build: " Finished searching libraries Finished pass 1 Generating code xxxx.cpp(1109) : fatal error C1001: An internal error has occurred in the compiler.

    - question about the processes created in VC Hi, I am new to the windows platform and working in VC++ on WIN-2000 platform. I have a process P1. P1 has to create another process P2 ( I'm using CreateProcess API for the same). Now if some one kills P2 or P2 exits gracefuly, is there any any for P1 to know that P2 has exited. Similarly if P1 exits then is there any mechanism so that P2 can know that P1 has exited. Pls solve my problem Thanks in advance Vidyut Gupta Tag: Dll Entry Point Name Tag: 250156

    - Why map work like this? I'm using VC++ 6.0, I just started to learn container and iterator, As I found a problem about container:map like below: map<int, int> intmap; for (int i = 0; i < 10; i++) { intmap[i] = i+1; } intmap.erase(2); map<int, int>::iterator it; if ( (it = intmap.find(2)) != intmap.end()) { cout << intmap[2] ; } the result is: 0 I had thought the key: 2 should have been erased, why it is still in and just change the coresponding value to 0?

    - "Curiouser and curiouser.", said Alice. "WTF?!", said Joe. The following SDK program works fine on my Win2k PC. I start trying it out on a WinXP machine: Things are looking bad now: it will only run in debug build. In release build it just exits (no crash, just doesn't start properly). I track it down to the part marked with "THE REALLY IMPORTANT BIT IS HERE" (see psuedo code, below). (I couldn't find the point of failure, because my attempt at logging each point just caused everything to work again (hmmm...)). WITHOUT that code block, the program just exists prematurely. WITH that code block, the program runs fine (note that the block is AFTER the message pump). If I move the code block in front of the message pump, it still works. IF I remove the volatile keyword, the program stops working again. If I remove huge chunks of other code (not shown), it makes no difference. Is it a thread issue with directX being initialised in a separate thread from WinMain? If I don't create the thread, I get the same behaviour as described above. I'm using the multithreaded libs. I could leave in the volatile loop, but I don't like not knowing why. If I build with optimisations turned off, I get the same behaviour. In fact, just tested it with for(x= 0; x < 1; x++){}; removed (leaving only the volatile declaration - unreferrenced variable), and with optimisations turned off, it had the same effect (program worked). With optimisation on, it looks like it's been optimised away (program stops working). So, what the frig is going on? Any ideas? pseudo code: WinMain(){ CreateEvent to check for previous existance. Read and Write a couple of DWORDS to the registry Register a Window Class hwndApp= CreateWindow _beginthreadex (myThreadProc) check current user's locale. Add a tray icon // normal message loop stuff MSG msg; ZeroMemory(msg) while(msg != WM_QUIT){ PeekMessage() TranslageMessage() DispatchMessage() } // THE REALLY IMPORTANT BIT IS HERE. { volatile int x; for(x= 0; x < 1; x++){}; } } myThreadProc(){ set up directx. etc. } Tag: Dll Entry Point Name Tag: 250108

    - Using MSHTML, how to get a parsed tree of an HTML source file? I am using VSC++2005. It is an MFC project, hosting MSHTML. The documents I read say that MSHTML can parse HTML documents but I could not find info about the format of the parsed tree and if it can be accessible to the hosting program. If there another HTML parser, especially if it can be incorporated into my program, that can produce an accessible parsed tree, that will be interesting too.

    - problem making background of static text transparent Hi, I wrote my own Splash class and in this class, i have a place for displaying messages at the bottom on my window. To display messages, i've created a static text window, thanks to CreateWindowEx. I've overloaded my WndProc with my own window procedure but i still have some problem to make my text with transparent background. I suppose 2 ways exists : - creating a brush of my text window area and using it before to write new text message - to make my text tranparent using setBkMode here is my code from my WndProc: ... case WM_PAINT : HDC hdc; // declare a handle to the device context hdc = GetDC(hWnd); // hWnd is the handle of my Text box created with CreateWindowEx SetBkMode(hdc, TRANSPARENT); // set transparency SetTextColor(hdc, RGB(0,0,0)); TextOut(hdc, 0, 0,MyMessage, strlen(MyMessage)); ReleaseDC(hWnd, hdc); case WM_ERASEBKGND : return true; ... unfortunately, when i display my first message, everything is ok, but problem happens after (during displaying of my second message)... it's written on the first one, so it becomes unreadable... I tried to make my first message disappears but except to create brush from initial state of my hWnd, i don't see how to solve this issue. Moreover, i have some problem to create a brush from rectangle of my textbox and to use it after. Could someone help me to solve my transparent problem ? thanks a lot, Maileen Tag: Dll Entry Point Name Tag: 250080

    - Dualprocessor support Hi, I just finished work on my current project - but one thing remains: multiprocessor support. My project consists of a vb.net executable (just for gui etc.)that does several callings on a specific C++ Dll. Now, the DLL creates a new thread, that consumes a lot of cpu time. If there is multiprocessor on the local machine, I'd like this thread to run on a specific CPU (to increase speed) - but I have several questions about this: - Is there any code changement necessary? e.g. Does Windows automatically place my thread on one cpu if it gets under heavy load? - How can I detect the numbers of CPUs present (in C++ or .net)? - Would it make sense to use e.g. the intel compiler 9 for this?

    - Some members of TypeLib libraries can't be found even in MSDN ?! Using VS2005 Beta 2 for an MFC project. When looking to add a (MFC) class from the TypeLib "Microsoft HTML Object Library<4.0>" library, of the many listed members is one called DispHTMLBody. When searching for spec of this member, it is not found neither in the VS2005's help nor is it found in the entire MSDN. This is just an example and it is true for many other members of other libraries as well. So how do users find out info about the various pieces? Thanks, David Tag: Dll Entry Point Name Tag: 250050

Hi,

MSDN documentation states:

"The name DllMain is a placeholder for a user-defined function. You
must specify the actual name you use when you build your DLL."

How do you actually accomplish that? I have not been able to find that
in the VC.Net documantation.

Many thanks,

Short answer: Use the /ENTRY linker option

Longer answer: You don't want to do that

Comprehensive answer: See here

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vccore/html/_core_Run.2d.Time_Library_Behavior.asp

To make a long story short, the operating system doesn't care a whit about
the name of the function. But when using VC++, _it_ sets the entry point at
its own runtime's initialization. That done, it calls your initializer.

Maybe it would be nice if it let you choose the name you like, but it
doesn't. Just it has been carved in stone that there must be main() or
WinMain() ...

Regards,
Will
