    - QueryPerformanceCounter Resolution I had assumed that QueryPerformanceFrequency is the resolution for the system they are used in. You are likely to get the best answer to this question in the microsoft.public.win32.programmer newsgroup. Tag: Visual C++ General Using GetFileTime and SetFileTime Visual C++

    - sprintf_s is not a member of global namespace I neglected to mention that this is a C++ project, so String.Format isn't an option. Also, I'm not using sprintf_s anywhere, although I am using sprintf in a few places. The error message points to Microsoft code, not mine. The file is C:\Program Files\Microsoft Visual Studio 8\VC\include \xlocnum, and the offending code starts on line 960, here: Code Block _VIRTUAL _OutIt __CLR_OR_THIS_CALL do_put(_OutIt _Dest, ios_base& _Iosbase, _Elem _Fill, long _Val) const { // put formatted long to _Dest const size_t _Buf_size = 2 * _MAX_INT_DIG; char _Buf[_Buf_size], _Fmt[6]; return (_Iput(_Dest, _Iosbase, _Fill, _Buf, ::sprintf_s(_Buf, _Buf_size, _Ifmt(_Fmt, "ld" , _Iosbase.flags()), _Val))); } The error message sounds to me like it sees this reference to sprintf, but can't find its definition in the global namespace. Maybe I need to include a VS 2005 specific library Thanks for the replies, Dennis Tag: Visual C++ General Using GetFileTime and SetFileTime Visual C++

    - How to enum access permissions and SIDs Look at WMI. I used it to do something similar and I spent a lot of time figuring it out. After I did that, someone wrote an article describing how to do what I had spent a lot of time figuring out. If you can find that article and use it then that will save you a lot of time.

    - Menu limitations I meant the limit for an individual menu (not the data size limit). By the way, are you dynamically populating the menu or are you entering these 8000 entries into the resource editor If the latter, I wonder if it's a limitation of the resource compiler.

I'm using VS2005., and here's the code sample. http://theand.net/myTest_MFC.zip I haven't set the options for Release version, so I recommand you to compile it in Debug version. I'd be very very grateful if you could check the actual code for me, and thanks for your reply :-) Oh, the reason I didn't create the dialog on heap was because I was afraid when the process terminates, memory leak would occur. And when I've followed the function call which made the termination, I found out it was before the code goes out of scope. Thanks again!

    - Question on Automating Word Passing Parameters Sahir Shah wrote: Starting Word with -a switch does not prevent add-ins it just starts Word without the add-ins. You can do the same thing using automation by iterating though the Application object's AddIns collection and calling delete on each AddIn object. Assuming that use of the "-a" parameter is what is needed, regardless of what it does, then is it easier to use automation instead than to use ShellExecute or CreateProcess Tag: Visual C++ General Using GetFileTime and SetFileTime Visual C++

    - Forms drawing order I handled it this way: Code Snippet private: System::Void Form1_Activated(System::Object^ sender, System::EventArgs^ e) { if (formInfo->TopMost != true) formInfo->TopMost = true; } private: System::Void Form1_Deactivate(System::Object^ sender, System::EventArgs^ e) { if (formInfo->TopMost != false) formInfo->TopMost = false; } Those conditions are needed. Without them it just behaves improperly - check. It is also worth looking at BringToFront() method. Tag: Visual C++ General Using GetFileTime and SetFileTime Visual C++

    - reinterpret_cast Hi agian! I have this code now, I was using ifstream, but it was well over my head, didn't understand it. But what I'd like to do with this code is get the buf to read in 64 bits (8bytes), which is does. But I would like to output the decmial value of that interger. However it seem just to but the 8 bytes back into the txt file. How do I get it to print of the number from the buffer the interger being displayed by value Oneline, is not correct. I can't figure out what it is doing Eventually I'll get this program to read in a whole file, I was thinking of 8byte at a time, and print it off to a file. Using a while(!eof) statement, please would you let me know if that's not possible #include <stdio.h> #include <stdlib.h> int main( void ) { unsigned __int64 Oneline; char buf[ 8]; int index; FILE *fptr; if (( fptr = fopen ( "test.jpg" , "rb" ) ) == NULL ){ printf ( "Cannot open file\n" ); exit ( 1 ); } fread ( buf, 1, sizeof (buf), fptr ); fclose ( fptr ); if (( fptr = fopen ( "Kounter-report31.txt" , "w+" ) ) == NULL ) { printf ( "Cannot open file\n" ); exit ( 1 ); } fprintf(fptr, "%I64u\n" ,Oneline); fwrite ( buf, 1, sizeof (buf), fptr ); fclose ( fptr ); } Thanking you kindly for you time James Tag: Visual C++ General Using GetFileTime and SetFileTime Visual C++

    - dcom error after removing windows 2003 server sp2 patch Hi all, i have an application working fine, until I installed windows 2003 server sp2 patch. This application is using dcoms in a no domain to communicate with another application. On checking the event viewer, I encountered this error: DCOM got error "The service cannot be started, either because it is disabled or because it has no enabled devices associated with it. " attempting to start the service ImapiService with arguments "-Service" in order to run the server: {520CCA63-51A5-11D3-9144-00104BA11C5E} How do I solve this error I had tried to go Add/Remove Program and removing sp2 from there but to no avail.

    - CreateObjrefMoniker and DisplayName only good for one call to GetObject? I'm doing the following LPMONIKER pMkr = NULL; HRESULT hr = CreateObjrefMoniker(pUnk, &pMkr); LPBC pBctx = NULL; hr = CreateBindCtx(0, &pBctx); LPOLESTR displayName; hr = pMkr->GetDisplayName(pBctx, NULL, &displayName); and then passing the displayName over to a VBA macro in an instance of Excel I am automatting where I call GetObject(displayName) to get a reference to my object and it works fine the first time but the second time it fails with "Object not registered" 0x800401fb (even though the object is still valid and up and running). This behavior is not documented (that I can find) and so I'm wondering is this the correct behavior or have I done something wrong Tag: Visual C++ General Using GetFileTime and SetFileTime Visual C++

    - how to run a function that returns non-void values on a new thread? The problem with your code is that you are simply spawning a thread and asking it to put some return value. You can't make sure that the value has been updated to the pointer because these threads are different entities. You should synchronize your thread execution by using Wait functions (WaitForSingleObject etc..). If both of your threads acecssing the same data,, you may need to put some locks to synchronize the access. I've not that much used with MFC thread classes, but withe native CreateThread and other realted functions. I think the error you are getting because of the calling convention problem. You can see a bunch of articles in codeproject or some other your facorite website. MSDN also has a well documentations on same. I think you learn yourself than we explain about threads and synchronization http://www.codeproject.com/threads/ Tag: Visual C++ General Using GetFileTime and SetFileTime Visual C++

    - Member function pointers johnr's idea is fairly close to a good one. When you override the button you add a new member function and member variable. void CMyButton: etPointer(MYPTR* mPtr); MYPTR* CMyButton::myptr; The MYPTR is a function pointer to the function you want called. typedef void (MYPTR*)(/*Params*/); (I apologise if the above typedef is not correct since I don't have access to all my references right now) Once you have this then you set myptr with the SetPointer method and then you override the OnButtonDown method calling the myptr function pointer. myptr(/*params*/); Maybe a look into pointer to members too would be a good idea. johnr: It is true that native C++ doesn't have delegates but they have function pointers so the basic ideas can still work. Delegates are really type checked functio pointers anyway. Tag: Visual C++ General Using GetFileTime and SetFileTime Visual C++

    - ReadFile() doesnt read the entire file "fread automatically checks for EOF and stops if it encounters one but for ifstream, we need to check it" Actually ifstream checks for EOF too. If you try to read from ifstream after the EOF character it won't work. In fact ifstream uses fopen/fread/fwrite/fclose under cover so it inherits the same behavior. If you don't want this to happen (stop at EOF) you need to open the file in binary mode: fopen("d:\\test.bin", "rb"); or ifstream s("d:\\test.bin", ios_base::binary | ios_base::read); As for ReadFile it does not process EOF or any other special characters. It's the fread function that does this. Tag: Visual C++ General Using GetFileTime and SetFileTime Visual C++

    - Auto batch build with different #define directives Just use the cl.exe command line option /D to define your customer define instead of defining it in the .h file. Then have your build process build with each customer define in turn. You're simply pushing the control over which customer you're compiling for up out of the code into the make system, where you can automate making several different ways easily.

I have not installed the SP, and will not be able to install it for another 48 hours while I am on a mobile internet connection. But I would be truly amazed if such basic things as the class wizard do not function without the SP. Would be grateful if this information helps to arrive at some more concrete conclusion. CKR If it is a known problem then it will have been fixed or is being fixed. If it has been fixed then it is likely in the SP.

    - Unable to find an entry point named 'HidD_GetHidGuid' in DLL 'HID.DLL'. I want to use the HID as a driver to communicate to a simple peripheral. When I call the 'HidD_GetHidGuid' function I get the subject error. If I run 'dumpbin.exe' on the 'hid.dll' the entry point is there with that name! I'm using the 'hid.lib' in 'winddk\3790.1830\lib\w2k\i386' in the linker and it builds okay. If I run 'dumpbin.exe' on 'hid.lib' the exported names are listed are decorated. I would understand if the error listed the decorated name '_HidD_GetHidGuid@4' as the name that couldn't be found. I have the include files 'hidsdi.h' and 'hidclass.h' bracketed with 'extern "C" {}'. I get no errors or warnings when I build the project. I'm really confused. Tag: Visual C++ General Using GetFileTime and SetFileTime Visual C++

    - msvcr80.dll not found Hi, If error has disappeared after you copied dlls to system32, that means that your application is built with manifest or there is not .manifest file in applicaiton local folder. You may find more information about changes made to VC++ libraries in MSDN docs http://msdn2.microsoft.com/library/bxf4ee9f(en-us,vs.80).aspx or on my blog http://blogs.msdn.com/nikolad/archive/2005/03/18/398720.aspx . Long story short, deployment model for VC++ libraries is changed in VS2005, you application needs to have WinSxS manifest file next to it or embedded inside of it to direct OS loader to a correct version of VC++ library. We have more detailed docs in latest builds of VS2005. Thanks, Nikola Tag: Visual C++ General Using GetFileTime and SetFileTime Visual C++

    - #pragma mak_public() has strictly no effect Hi, I have been struggling for hours now with the famous "candidate function(s) not accessible" From what I understood #pragma make_public should solve this problem but it doesn't. Here is the context. The structure which is responsible for this pb is from the PKCS#11 library defined in pkcs11t.h included in cryptoki.h. In DLL A: #include "cryptoki.h" public ref class ClassA { public: ClassA(CK_ATTRIBUTE_PTR pAttr, CK_ULONG count) { // Do something with pAttr } } In DLL B: #include "cryptoki.h" public ref class ClassB { public: static void MyMethod() { CK_ATTRIBUTE_PTR pAttr = CK_ATTRIBUTE[] { // Initialisation}; ClassA^ classA = gcnew ClassA(pAttr, 1); } } In DLL B I get the anoying "candidate function(s) not accessible candidate function(s) not accessible" error on the constructor of ClassA called in MyMethod. In the documentation of MS it is said that #pragma make_public(CK_ATTRIBUTE) should solve the problem. Unfortunately using this in DLL A leads to a new error at LINK time Error 1 error LNK2022: metadata operation failed (80131195) : Custom attributes are not consistent: (0x0c0001a7). CryptokiAttribute.obj and using it DLL B has strictly no effect. Does anyone has already managed to use this s called solution in the above situation.

Hi,

I need to reset file creation and read it immediately. I have written the code as shown below

if (SetFileTime(hfile, &fts, (LPFILETIME) NULL, (LPFILETIME) NULL))
FlushFileBuffers (hfile);
if (GetFileTime(hfile,&ftg, (LPFILETIME) NULL, (LPFILETIME) NULL))

Now both this fts and ftg should be same. MSDN is giving remarks saying that across all file systems behavior may not be the same.

Please help in creating this code which should work from windows 98 to windows vista.

Re: Visual C++ General Using GetFileTime and SetFileTime

Marius Bancila

There are limitations of the file systems. You can't get across that.

Not all file systems can record creation and last access times and not all file systems record them in the same manner. For example, on FAT, create time has a resolution of 10 milliseconds, write time has a resolution of 2 seconds, and access time has a resolution of 1 day (really, the access date). Therefore, the GetFileTime function may not return the same file time information set using SetFileTime. NTFS delays updates to the last access time for a file by up to one hour after the last access.
