    - InternetOpenURL but with password Ok, I use InternetOpen, followed by InternetOpenURL, followed by InternetReadFile to read certain files off of my server. Now I want to use it, to open a file that is in some admin section of the server. When I open that URL using IE, IE asks me for the name and password. As a test I tried that URL on my current app, and the file that came back as authorization required, no prompt anywhere for a password or username. How can I do this in C (not C++ mind you)? And how can I do it safely? Or does wininet.lib handle this? Thanks ahead. Tag: coderwiki.com is starting and needs you! Tag: 265768

    - Message Compiler - specify customer bit per message Iâ??m very new to C++ (three weeks of learning on my own) so please bear with me. Iâ??m creating my first message file to be compiled with the mc.exe message compiler and I want to turn on the customer bit for certain error codes and not others. It looks like the only way to turn on the customer bit is by using the â??c switch on mc.exe. Unfortunately that causes ALL error codes to use the customer bit. Is there a way to do this without creating two separate message files? (One with the customer bit and one without) Hereâ??s the specific scenario in case the question wasnâ??t clear. Iâ??m creating a message file contains event messages/error codes and event categories/codes. Turning the customer bit (bit 29) on for ALL the messages means that you need 32bits to reference any of the messages. But since the ReportEvent function uses a 16bit variable for the category code, you have no way to reference the 32bit category codes. Thanks in advance for your help. -- I''m a very intelligent person... unfortunately I lack the vocabulary to express my ideas. :) Tag: coderwiki.com is starting and needs you! Tag: 265761

    - Changes to the C4244 warning? We compile our code under warning level 4 and want to have the C4244 warning enabled as it sometimes catch problems in the code. However, consider the following code: unsigned char a, b; a += b; // Generates warning a = a + b; // Does not generate warning The problem is that C++ will expand the type of the + expression to int and then implicitly convert the int to unsigned char, which should generate a warning. We dunno if the compiler folks at Microsoft thought "hey thats silly to warn here" and disabled the warning for the regular assigment but forgot to disable it for the += assignment or if they made an error not reporting the implicit conversion of the type in the regular assignment with the C4244 warning. We would very much like VC would not warn for either assignment operators when types are implicitly expanded and then implicitly reduced as this is never a warning you care about. Currently, we have to use the second form to avoid the warning but if the VC teams decides to warn here also we really need to write: a = (unsigned char)(a + b); And this kinda sucks. (Although it is really C++ that sucks here) Regards Ulf Johansen Tag: coderwiki.com is starting and needs you! Tag: 265746

    - Help!! %n is diabled in sprintf in VS 2005 Hi, We have some code that uses %n as a conversion specifier in sprintf. That used to work fine in VC 6.0 and also in UNIX. But now, in VS 2005 that sprintf statement crashes. During the debugging I found that %n support is disabled in the source file output.c. I do need to use the dll version of the C run time library. Is there any way I can continue to link to the C run time library without any source code change? Do I have to change all my existing code to use sprintf_s which requires an additional argument? If that is the case it is a pain. What happens to the portability? Unix does not have sprintf_s. Thanks, Vnm Tag: coderwiki.com is starting and needs you! Tag: 265730

    - VC6 SP6 I have installed SP6 for VC6. This was done to deal with a problem with the ios destructor issue referred to in KB814308. After installing the service pack the file _ios.cpp was still the same that was in previous service packs (date on the file, 2000-06-13). If you refer to the individual knowledge base article it shows a file with the date of 2003-02-05. I was wondering does anyone have the hot fix that is referred to in the knowledge base article. I have asked a support person at Microsoft as we have an outstanding issue with named pipes and when he looked into finding the hotfix he said that he was unable to locate it.

    - IE toolbar ,How i can reflect the Settings Hi My IE toolbar is based on the Microsoft sample KKBar. I have draw a lot of buttons on it in which some are simply pushDown buttons and some are dropdowns.Beside this I have Made a Setting button.By which user can Customize the Buttons on toolbar,means S/He can select the buttons and deselect the buttons from a Property page. This information i have placed in Windows registry.When I create the toolbar i Create the toolbar based on the registry data that which button i have to appear and to which Button i have to HIde . I have completely Done it.they appear and disappear properly. But the trouble starts when i Create the toolbar i can decide From the registry data that which button i have to make appear and which button i have to make disappear. If the user Selects the setting and change the options (suppose he want to display one more button from the setting),How i can refresh my toolbar to show that button on the same instance of IE. Plz if some one knows tell me .i will be thankful to him.Buttons are displayed when i start another instance of IE,this is just bcoz the Data in the registry has been changed by the previous instance,But i want also to be on the instance that is changing the options.

    - InterlockedCompareExchange64 under VC++ 6.0: in-line assembly using cmpxchg8b ?? I am trying to implement an atomic compare-and-exchange of a "double" type, under VC++ 6.0 for WinXP. The Windows API function of InterlockedCompareExchange64 is not available for WinXP (it's only available for Vista, see http://msdn.microsoft.com/library/en-us/dllproc/base/interlockedcompareexchange64.asp ) . There is a compiler intrinsic function of _InterlockedCompareExchange64 (see http://msdn2.microsoft.com/en-us/library/ttk2z1ws(VS.80).aspx ), but this intrinsic seems to be available only for more recent versions of VC++ (such as VC++ 2005), and it's not available as an intrinsic for VC++ 6.0. So, I think that I need an in-line assembly function which, like the 2005 compiler intrinsic, uses the cmpxchg8b instruction. In-line assembly, however, is beyond my capability. I found user-mode code that uses in-line assembly and the cmpxchg8b instruction at this thread in microsoft.public.win32.programmer.kernel (see the next-to-last post): http://groups.google.com/group/microsoft.public.win32.programmer.kernel/browse_thread/thread/ecc0a35d9fcef3b5/0e3b6a23d301a62a . The code doesn't work for me. Here's what I mean by "doesn't work": I implemented the function in a singly-threaded environment, simply to test whether the function properly stores the correct double value at the destination location. As expected (since we're in a singly-threaded environment), the function's return value indicates that the current value of the destination agrees with the comparand's value, and that the exchange was successful. However, the value that actually gets stored at the destination address is bizarrely corrupted, and does not agree with the exchange value. Can anyone offer any insights (other than a suggestion to upgrade to VC++ 2005)? Maybe someone knows of the assembly code used by the current compiler's intrinsic?

    - Send/Post Messages on Vista Hi all, There're two apps, A and B on Vista. Using FindWindow() with caption of a window, it proves that B can find the window of A. However when B calling PostMessage() to shot down A of the window, it doesn't work. My understanding is that both A and B are in the same session since they are running under the same user login. Does this mean that both SendMessage() or PostMessage() will not work anymore even in the same session on Vista? If not, there's a way to implement this, better off without any dialog pop-up for user's interaction? Thanks, DH Tag: coderwiki.com is starting and needs you! Tag: 265681

    - rs232! Hello, As I read the following document a few times at: http://www.codeproject.com/system/serial.asp given to me by fellow friend Jochen in my previous post I am ready to give rs232 a crack at it! :) I am using the "Windows messages" option of rs232 interfacing (See document). In spite of me using VC++ for 9 months now, I still consider myself a beginer when it comes to much of the language and especially the VC++ GUI. Here is my first problem. I have started to code for the rs232 as indicated in the above link's web document as so: #define STRICT #include <tchar.h> #include <windows.h> #include "CSerialWnd.h" I still don't know what the "#define STRICT" statement is doing there? But I am just copying the sample. Given the above include statements I get the following error at build time: c:\_DTS_PROGRAMMING\C_PROGRAMMING\vc++\MY_APPS_LAB\RS232Test_XPPLC\WndProc_CW1.cpp(20): fatal error C1083: Cannot open include file: 'CSerialWnd.h': No such file or directory In the document, it clearly states that I need to include the serial class header file, in which I did, and I must make sure that the header-files of this library are in my compiler's include path. Up to now all I am used to is including windows.h and some odd header file that I created. I don't know how to include the header files of CSerialWnd library in my compiler's include path. I didn't get very far, but its a start and I don't know what to do, I tried to look at the project properties to see if there is a field that requires include paths, or something like this....

The fragment flags and offset look like this: 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Identification |Flags| Fragment Offset | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ I tried this:typedef struct IPV4_HDR{...uint16_t ip_id; /* identification */uint16_t ip_mf:1; /* more fragments flag */uint16_t ip_df:1; /* dont fragment flag */uint16_t ip_evil:1; /* evil bit */uint16_t ip_fo:13; /* fragment offset */...} IPV4_HDR;Which results in this packing:|OOOOOOOO|FFFOOOOO|Where the Os are the fragment offset and the Fs are the flag bits. As you can see,the 13 bit field is byte swapped, as you'd expect if the 13 bit field reallywas an unsigned short. But this isn't how the field is layed out on the wire.Is there any way to do this using bitfields on the Microsoft compiler? Tag: coderwiki.com is starting and needs you! Tag: 265612

    - Monitor a directory using WaitForMultipleObjects Platform : Windows2000, XP, Microsoft Visual C++ .NET (Version 7.1), Hello, I need to process the files in a directory immediately the moment it gets deposited in a directory. I am trying to achieve this by running WaitForMultipleObjects , FindFirstChangeNotificationAPI, FindNextChangeNotification in a While loop in the Run() of one of my worker threads of my multithread application. I get the events for the files that were deposited after the WaitForMultipleObjects was invoked in the while loop. However those files that get deposited in the folder in the split of second before the WaitForMultipleObjects is invoked are not getting reported i.e. I am not getting their handles. Is there any other API or code that can help em achieve the same without losing the notification of the files deposited? Any eveident problem that you see as to why this should happen? Any poitners would be of great help Thanks and Regards Ganga (Please see excerpts of code below:) int CMyWorkThread::Run() { ASSERT_VALID(GetWork()); CDirEventReceiverWork* dirWrk = dynamic_cast<CDirEventReceiverWork*>(GetWork()); try { DWORD timeout = GetCycleTime(); BOOL waitAll = FALSE; DWORD dwWaitStatus; while (TRUE) { try { dirWrk->GetEventDirectoryList(con); dwChangeHandle= FindFirstChangeNotification( lpDir, // directory to watch subDirState, // do not watch subtree FILE_NOTIFY_CHANGE_CREATION |FILE_NOTIFY_CHANGE_LAST_WRITE); // watch file name changes AddToHandleMap(dwChangeHandle, &ci); dwChangeHandles = GetHandleList(); int nHandles = m_pDirEventServer.GetHandleMap().size()+ 2; dwWaitStatus = WaitForMultipleObjects(nHandles, dwChangeHandles, waitAll, timeout); if(dwWaitStatus == WAIT_TIMEOUT ) { //Refresh receiver list continue; } if((dwWaitStatus == WAIT_OBJECT_0 + 0) || (dwWaitStatus == WAIT_OBJECT_0 + 1) ) { //signalled kill event break; } if((dwWaitStatus <= (WAIT_OBJECT_0 +1)) || (dwWaitStatus >= nHandles)) { ASSERT(false); ostringstream ost; ost << "Invalid wait return value [" << dwWaitStatus << "]"; CABIException(PROGRAM_ERROR, ost.str(), __FILE__, __LINE__); continue; } if(dwWaitStatus == m_pDirEventServer.GetHandleMap().size()) { //signalled kill event break; } //Process the files } .....................

    - Visual C/C++ 6.0. Using SEH I'm facing a problem in using SEH (structured exceptions handling) in VC 6.0. Please, create (using Visual C/C++ 6.0) an Empty Console application. Use following source to build the application: -------------------------------- class A { public: operator const __int64() const { return 33i64; // random number } }; inline bool operator!=(const A& val1, const __int64& val2) { return false; // doesnt matter what it returns } static A g_a; bool func() { __try { return (g_a != 0i64); } __finally { } return 0; } void main(void) { // Check the returned value bool bRetVal = func(); } // Place a breakpoint here and check the value of bRetVal -------------------------------- Run the application and check the value returned by func(). In my case it is 24, but it should be false <zero>. Actually (after number of tests) I found that it is a random number. Can somebody, please, explain what is going on? This code should be working, or I should get a compiler error. I'm not looking for workaround. I just want to understand - am I wrong, or there is something with the compiler. Thank you !!! * I've tried the same source using VC 2003 and it works fine. Tag: coderwiki.com is starting and needs you! Tag: 265596

    - Memory Management Hi everyone, I have implemented a memory manager for some SDK I'm working on (a game engine). The primary goal of this memory manager is to reduce fragmentation, to perform fast allocation of small blocks of memory, and to give more detailed information about memory leaks. This manager works fine, and without problems. Now, as you might have guessed already, my problems are the operators new and delete. I wish to overload them in a *safe* way, such that the memory manager is automatically used. I do not want to use class-based new/delete operators. It also has to work properly with other libraries, including the STL. I did overwrite the global operators, and that woks, but it just doesn't feel safe. I realize that there's a good chance, that you'll tell me, that there's just no good and safe way to do what I want. But maybe I'm wrong, and someone here's got this great idea :-) There's just got to be some way to write a cusom memory manager. Thanks, Niki Tag: coderwiki.com is starting and needs you! Tag: 265587

    - LoadLibrary question Hi All, Could anyone please let me know if it is possible to load a library which has been built with a /MD compiler witch into an exe which has been build with a /ML compiler switch using 'LoadLibrary'? I am sure that it can be done, but I want to know what will be the implications of such a load? Would that be a good idea? Also, if at all I am to load a dll into an exe which has been statically linked to C runtime libraries (using /ML option), should the dll to be loaded be also statically linked to C runtime libraries or it will be OK if the dll has been dyanamically linked with C runtime libraries (using say /MD option)?

    - MS Developement Environment Toolbar Question I had someone code a piece of software for me so I bought Visual Studio .NET 2003 Pro so I could build the project should I ever have the need. I have all of the source code for the project. I open the project and click build and it goes thru fine. I open the project and the toolbar icons are off...its like the edge of one gets cut off and shifted to the next toolbar icon..When he compiles it this doesnt happen because I have a compiled exe of the ones he did. Is there a setting that is causing this??? If you need more info let me know and I will post up. Tag: coderwiki.com is starting and needs you! Tag: 265563

    - question about how threads work I am new to threading and I have the following program, but I am unsure about one thing. This program prints out 5 numbers from 0 to 4 or if I take out the Sleep(1000) in IFK_ThreadedRead, it prints out 0 to 405. What I don't really understand is why if I increase the Sleep(5000) statement in the test_interfaceKit function just after the thread is called, it will print out more numbers. I would have thought that the function the thread calls would print out 0 to 999, end the thread and then wait for 5 seconds. It acts like the thread is constantly being called. I am a bit confused about this and I thought I would ask someone who knows a bit more how threads work. Hopefully, you can clear this up for me. Z.K. ---------------------------------------------------------------------------- int __stdcall IFK_SensorChangeHandler(CPhidgetInterfaceKitHandle IFK, void *userptr, int Index, int Value) { printf("Sensor %d is %d \n", Index, Value); return 0; } DWORD WINAPI IFK_ThreadedRead(LPVOID lpdwParam) { CPhidgetInterfaceKitHandle IFK = (CPhidgetInterfaceKitHandle )lpdwParam; while(1) { for( int i = 0;i < 1000;i++) { printf("num = %d\n",i); Sleep(1000); } } printf("Closing down IFK Read Thread \n"); return 0; } int test_interfacekit() { HANDLE m_ThreadHandle; unsigned long m_sThreadIdentifier; int result = 0; CPhidgetInterfaceKitHandle IFK = 0; CPhidgetInterfaceKit_create(&IFK); result = CPhidget_open(IFK, -1); if (result) { printf ("No InterfaceKit found...\n"); return 0; } CPhidgetInterfaceKit_set_OnSensorChange_Handler(IFK, IFK_SensorChangeHandler, NULL); m_ThreadHandle = CreateThread(NULL, 0, IFK_ThreadedRead,(void *)IFK, 0, &m_sThreadIdentifier); printf ("And we wait for it to shut down from an error, or 10 second timeout\n"); Sleep(5000); CPhidget_close(IFK); CPhidget_delete((CPhidgetHandle )IFK); return 0; } int main(int argc, char* argv[]) { test_interfacekit(); return 0; } Tag: coderwiki.com is starting and needs you!
