    - VS 2005 and Manifest for runtime dlls Hi all, I'm having some problems with Visual Studio 2005 and even though I read everything I could find in MSDNL I still couldn't find the answer. Mainly my problem is that even though the manifest needed for the MS runtime library is embedded into the binary the C:\Program Files\Microsoft Visual Studio 8\VC\redist\x86\Microsoft.VC80.CRT\Microsoft.VC80.CRT.manifest is still needed. Detailed: I did the following steps: 1) New Project -> Win32 Console Application -> Empty project 2) Add new .cpp file with some code (as easy as possible), eg: #include <stdio.h> void main() { printf("MOMO"); } 3) Build the project in Release 4) Open the built .exe in the Visual Studio IDE (File -> Open -> File) => we can see the RT_MANIFEST being indeed 1, as suggested by MSDNL, which means the manifest is embedded into the binary. 5) Copy this new binary, eg coco.exe on a Windows XP system with no Visual Studio installed Now there are the following scenarios: a) Run coco.exe on that machine => error "The system cannot execute the specified program.", when run from cmd prompt, or "This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem.", when double-clicked in explorer. Not working might be normal as there are no runtime DLLs b) copy the C:\Program Files\Microsoft Visual Studio 8\VC\redist\x86\Microsoft.VC80.CRT DLLs (msvcp80.dll and msvcr80.dll) on the target machine in the same directory like the coco.exe and try again to run coco.exe => the errors like above. This is what I don't understand. Why isn't this enough taking in account that the manifest is embedded in the binary? c) If I also copy in the exact same directory where the DLLs and coco.exe are the file Microsoft.VC80.CRT.manifest from C:\Program Files\Microsoft Visual Studio 8\VC\redist\x86\Microsoft.VC80.CRT, running coco.exe will work. But doesn't that mean that I have an external manifest? If yes, means this is not what I want, as in MSDNL is stated that having an external manifest is not a good idea as this won't work if you load a DLL via LoadLibrary, so I want the manifest embedded. In other words, can somebody pls: I) explain why the scenario b) is not working II) the C:\Program Files\Microsoft Visual Studio 8\VC\redist\x86\Microsoft.VC80.CRT\Microsoft.VC80.CRT.manifest is always needed? Does this mean external manifest or not? III) what do I need to do in order to deliver on the target machine the DLLs in the same directory where the app is? (not WinSxS, and not a subdirectory of the application directory) Thanks in advance, Viv Tag: date and time Tag: 265091

    - Functor adaptor question I had a case today where I needed a functor that was a bound member function. Basically: class MyClass { ...bug free code omitted... void PrintMe( int x ) { printf( "%d\n", x ); } void A_Function() { ... std::vector<int> myList; ... std::for_each( myList.begin(), myList.end(), bound_mem_fun( *this, PrintMe ); // bound_mem_fun is made up ); } Am I correct in my conclusion that there is no such adapter in the standard library? It looks like there is one in Boost, and it only took about 8 lines of code to implement it, but I don't want to reimplement it if there is one built in that I missed. -- - Tim Roberts, timr@probo.com Providenza & Boekelheide, Inc.

    - Runtime error 6034 I recently convert a solution of several projects from Visual Studio 2003 to 2005. When distributing the binaries I encounter the problem which the exe cannot start. I did put all those DLLs and their manifest files, such as msvcr80.dll and Microsoft.VC80.CRT.manifest, in the same folder (at the same level) of the exe. However when starting the exe, it gives me a runtime error: R6034 An application has made an attempt to load the C runtime library incorrectly. Could people here point out the cause of such a problem? Note: I did build all modules with "Embed manifest" setting to "Yes". And copied all the manifest files for each modules into the same folder of the exe. Thanks! DH Tag: date and time Tag: 265066

    - IOCTL_DISK_CREATE_DISK Hi, I've been tasked with writing the front-end application to a storage array product. One of the features is a setup wizard to initialize/partition/format a new array. I've been looking into the problem and I'm having a hard time figuring out how to get this done. My expectation was that IOCTL_DISK_CREATE_DISK would initialize the disk for me (I haven't got to partitioning or formatting yet). However, after the DeviceIO call executes successfully nothing changes within the Disk Management Snap-In. Shouldn't the disk entry now say "Initialized"? Either the code or my expectations are incorrect =) Here's the code... HANDLE hDevice; BOOL bResult; DWORD junk; hDevice = CreateFile("\\\\.\\PhysicalDrive2", FILE_ALL_ACCESS, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING, 0, NULL); if (hDevice != INVALID_HANDLE_VALUE) { CREATE_DISK cd; cd.PartitionStyle = PARTITION_STYLE_MBR; cd.Mbr.Signature = 0x28; bResult = DeviceIoControl(hDevice, IOCTL_DISK_CREATE_DISK, &cd, sizeof(cd), NULL, 0, &junk, (LPOVERLAPPED) NULL); CloseHandle(hDevice); } Perhaps the signature field has something to do with the problem. It wasn't clear what I should set it to. I tried 0 and 0x28. Thanks for your help... Tag: date and time Tag: 265061

    - Including only once - What is best practice? What is the best practice to prevent duplication of includes? From what I can see, you can use: #pragma once at the top of included headers, or: #ifndef headerName #define headerName // header stuff here #endif If I create an include file that say needs <windows.h>, is it a best practice to then include that in that header file to sort of document that fact, and use one of the above techniques?

Here some code, if not enough, I give u more // the slider bars DDX_Control(pDX, IDC_SLIDER_COLOR_CHOOSER_1, m_sliderBars[0]); DDX_Control(pDX, IDC_SLIDER_COLOR_CHOOSER_2, m_sliderBars[1]); DDX_Control(pDX, IDC_SLIDER_COLOR_CHOOSER_3, m_sliderBars[2]); DDX_Control(pDX, IDC_SLIDER_COLOR_CHOOSER_4, m_sliderBars[3]); DDX_Control(pDX, IDC_SLIDER_COLOR_CHOOSER_5, m_sliderBars[4]); DDX_Control(pDX, IDC_SLIDER_COLOR_CHOOSER_6, m_sliderBars[5]); DDX_Control(pDX, IDC_SLIDER_COLOR_CHOOSER_7, m_sliderBars[6]); DDX_Control(pDX, IDC_SLIDER_COLOR_CHOOSER_8, m_sliderBars[7]); DDX_Control(pDX, IDC_SLIDER_COLOR_CHOOSER_9, m_sliderBars[8]); DDX_Control(pDX, IDC_SLIDER_COLOR_CHOOSER_10, m_sliderBars[9]); for (i=0; i<10; i++ ) { m_sliderBars[i].SetRange(0, 5000); m_sliderBars[i].SetPos(200); } The problem is, the first sliderbar sets its range between 0 and 100 and the position to 0, no mather what I do. This is not what I want it to do. Is there anything I did not take into account, or do I really have a problem and should look for a doctor checking my eyes. I am desperate, since I dont see, why it wont work. Would anybody show a little mercy and spend a few minutes for me please? Thank you in advance. Tag: date and time Tag: 264946

    - manifests and Vista Beta2 Not sure where the best place for this is as I can't find a 'Vista/programmer' type of newsgroup. I've got a VC 8 MFC application that I've written that installs fine on XP and on Vista Beta2 and runs fine on XP. But when I try to run it on a Vista Beta2 system, it complains that the 'side-by-side configuration is incorrect' and tells me to check the event log. I can't tell much from the event log but it tells me to run the 'sxstrace'. When I try to do that it tells me 'access denied'. Any ideas if this is just a Vista problem or if there's something I need to do with my build/setup so that it'll run on Vista? Thanks! Tag: date and time Tag: 264938

    - Cannot convert from 'Type' to 'const Type&' error with templates Hello, I encountered strange compilation error, so I want to hear what other people say before I blame the compiler. My environment: VC++2005, XP/Win2K. I made helper function, which helps to build predicates for many standard algorithms. The point of the function is that it compares certain member of the class instead of whole class object. Here's the code: --------- //////////////////////////////////////////// // Template class for composition f(g(x)) template<typename F, typename G> class compose_t : public std::unary_function< typename G::argument_type, typename F::result_type > { public: explicit compose_t(const F& f, const G& g) : m_f(f), m_g(g) {} typename F::result_type operator()( const typename G::argument_type& x) const { return m_f(m_g(x)); } private: F m_f; G m_g; }; // Template function to construct compose_t template<typename F, typename G> compose_t<F, G> compose(const F& f, const G& g) { return compose_t<F, G>(f, g); } //////////////////////////////////////////// // Sample class struct X { X(const char* s, int n) : s_(s), n_(n) {} const std::string& GetS() const { return s_; } std::string s_; int n_; }; //////////////////////////////////////////// // Helper function to form arbitrary predicate template < typename T, typename Func, typename Pred > compose_t<std::binder2nd<Pred>, Func> mem_match( const T& val, Func fn, Pred pr = std::equal_to<T>() ) { return compose(std::bind2nd(pr, val), fn); } //////////////////////////////////////////// // int _tmain(int /*argc*/, _TCHAR* /*argv*/[]) { typedef std::vector<X> XVec; XVec v; v.push_back(X("one", 1)); v.push_back(X("two", 2)); v.push_back(X("three", 3)); XVec::iterator it = std::find_if( v.begin(), v.end(), mem_match( std::string("two"), std::mem_fun_ref(&X::GetS) ) ); return 0; } --------- The problem is that mem_match doesn't compile. Compiler issues error C2783: could not deduce template argument for 'Pred'. So, now I tried this one: template < typename T, typename Func > compose_t<std::binder2nd<std::equal_to<T> >, Func> mem_match(const T& val, Func fn) { return compose( std::bind2nd( std::equal_to<T>(), val), fn); } This compiles without any problem, however I cannot control std::equal_to predicate from the outside of mem_match. I cannot specify std::binary_function as template parameter for std::binder2nd, since std::binary_function doesn't have operator() at all, and compiler rightfully complains about it. How can I control predicate for mem_match? Thanks in advance Alex Tag: date and time Tag: 264936

    - OOP problem! Hello, Just to not cause any contreversy: "I understand that class definitions go in headers and method implementations go in CPP files, however to simplify things, I put everything under one listing!" okay! "A_CTR" class derives from "actions" class and "actions" class derives from "components" class. ALSO: "T_CTR" class derives from "transitions" class and "transitions class derives from "components" class. So, its doing like a pyramid, with "components" class at the top, and where "actions" and "transitions" classes are right below "coponents". Further, "A_CTR" class is underneath "actions" and "T_CTR" is under "transitions". I guess this can be better viwed in the code below. Please consider the following code and see question after code: =============================================== class components { public: components(){} components(int Flag); virtual ~components() {} static int FLAG_AllTrueInCase; protected: }; //ADT class actions:public components { public: actions(){} virtual ~actions(){} virtual bool conv_BOOL_INPUT_INTERNAL( int Bool_ID_INPUT1,int Bool_ID_INTERNAL1, IO *io); protected: }; class A_CTR:public actions { public: A_CTR(){} virtual ~A_CTR(){} virtual int SYS_getCnstCount(int i_COunterID)const; virtual void setCounter(int i_CounterID,int i_CountCnst); protected: int iCount1Cnst; int iCount2Cnst; int iCount3Cnst; }; int A_CTR::SYS_getCnstCount(int iCounterID)const { ...other code... return iCount1Cnst; } void A_CTR::setCounter(int iCounterID, int iCountCnst) { ...other code... iCount1Cnst = iCountCnst; } //ADT class transitions:public components { public: transitions(){} virtual ~transitions(){} }; class T_CTR:public transitions { public: T_CTR(){} virtual ~T_CTR(){} virtual bool get_CTR_Ellapsed(int i_CounterID, int i_BranchDest); protected: int iC1CurrentCount; int iC2CurrentCount; int iC3CurrentCount; }; bool T_CTR::get_CTR_Ellapsed(int iCounterID,int iBranchDest) { int xxx; xxx = A_CTR::SYS_getCnstCount(1); /// *** ERROR! *** on this line! } =================================================== What if we are in a method of the T_CTR class and we wish to access a member of the A_CTR class? The following line: xxx = A_CTR::SYS_getCnstCount(1); /// *** ERROR! *** on this line! causes the following error: c:\_DTS_PROGRAMMING\C_PROGRAMMING\vc++\MY_APPS_LAB\XPPLC\WndProc_ClassMethods.h(375): error C2352: 'A_CTR::SYS_getCnstCount' : illegal call of non-static member function I somehow have the feeling I have coded something wrong *again*..... I am looking hard to find the problem, but obviously not hard enough, and furthermore, a book example does the same thing... I don't know what to make of it? Just when I thought that I was getting this classes stuff, I get this! :-) Can someone please tell me what am I doing wrong? *ALL* support appreciated! -- Best regards Robert Tag: date and time Tag: 264935

    - Form resource files Hi there. I apolgize for posting this again (from June 2nd) but I've been researching for many days now with no success. I have an app that will be reading arbitrary ".resx" or "resources" files passed on the command line for instance. Given only a resource file IOW, does anyone know: 1) How the app can determine if the passed resource file contains (localized) form resources (i.e., it stores a form) 2) If it does contain (localized) form resources, how can I then generate that form dynamically Note that the native .NET utility "Winres.exe" is able to do this but I can't figure out how (not without using techniques that appear to be undocumented). Any help would be greatly appreciated. Thanks. Tag: date and time Tag: 264931

    - Get filename and path of a file selected on the desktop Hi, Is there a way to obtain a filename and path (or just a handle of a file, but without knowing its name nor path) of a file(s) selected on the desktop (with LEFT click). As far as I know there's no such api function. "Shell extensions on right click" are NOT what I'm looking for... When I click a file in any window, Explorer runs a few functions like ReadFile, CreateFile and in some magical way gets it's name and path. I searched the web but with no luck. I could make a filesystem hook and intercept calls on functions like ReadFile or CreateFile, but I would need only those calls, that are made when I select one or more files in a Explorer window. And that is what I am not able to do, because of my lack of knowlegde on that topic. If you can, please help Tag: date and time Tag: 264917

    - OT: stroke "orientation" Sorry. I don't know any relevant newsgroups. What I want to do is to able to recognize a rear license plate of a car. Say due to the shot angles, the images are more or less skewed. At first attempt, I was trying to transform the images using affine transformation to make it erect 90 degrees as normal characters and compared with some predefined character shapes. The new characters recognized would be put into a nero-network. Now I have changed my mind, I would like to know how the letters strokes are orientated.

Is the only difference that you can only use the constructor when instanciating? If you have the constructor Point(int dx, int dy) { same as above}, the you could simply do this: int main() { Point pt(3, 2); } Thanks guys for helping a noob learn the in's and out's.

Normally, in C: struct NAME_TAG mystruct; vs. in C++ NAME_TAG mystruct; and so my guess is that the above type of pattern is to allow you to say something like this in C: NAME_TYPE mystruct; without the 'struct' keyword.

Most-friendly way, I don't know. I like to use two date and time picker
controls:

http://windowssdk.msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc/platform/commctls/datetime/datetime.asp

one set up to display a date and one the time.
