    - EnumJobs/GetJob problem... Hello everybody, I'm trying to monitor the Windows printing queue.

    - dependency issue, build instead of rebuild We have several projects where we #include "resource.h" in stdafx.h (I know, bad practice, but let's ignore that for now). For some reason when we make a change to resource.h and build the project, the compiler doesn't realise it needs to rebuild stdafx.cpp. It thinks everything is up to date. But when it compiles the .cpp file that uses the new ID we just defined, say, it gives an error that the ID is not defined, because it hasn't compiled the new resource.h. So any time we change resource.h, we have to Rebuild All instead of just Build. Any idea why that would be? Other .h files included in stdafx.h work just fine--when they change the compiler knows to rebuild stdafx.cpp etc. Nate Hekman Calgary, Alberta, Canada Tag: string Tag: 222157

    - This simple file I/O code should work but doesnt (VC6 ent. sp5) Hi all. I'll present this simple code straight away and then I'll sketcht the (irritating) problem: # include <iostream> # include <fstream> # include <ostream> # include <string> //# include <cstddef> <<<===== What for? What does it do? using namespace std; struct Customers { int Num; char Pkg; float Hours; string Bill; }; bool GetCust( const string& filename, Customers* P ) { ifstream InFile( filename.c_str() ); if( !InFile ) return false; // You could use a for loop too, if you wish. size_t Idx( 0 ); while( InFile>>P[Idx].Num>>P[Idx].Pkg>>P[Idx].Hours>>P[Idx].Bill ) ++Idx; if( !InFile.eof() ) return false; return true; } void DisplayCustomers( const Customers* P, const size_t Size ) { for( size_t Idx = 0; Idx < Size; ++Idx ) { cout << P[ Idx ].Num << " " << P[ Idx ].Pkg << " " << P[ Idx ].Hours << " " << P[ Idx ].Bill << endl; } } int main() { Customers People[49]; //PROBLEM CHILD RIGHT HERE, NEWSGROUP READERS! if( !GetCust( "CustomerFile.txt", people ) ) cout << "Error: Could not read file properly."<<endl; else DisplayCustomers( People, sizeof People / sizeof* People ); return 0; } Yes that's right, I was excercising basic file I/O. Look in main(). - If I declare "Customers People[49]" in main() then I'll get an exception error while running. Note that the file (CustomerFile.txt) has indeed 49 lines of customer data. No problem there. - But if I declare Poeple[50] in main() then everything works fine except for the fact that index-50-variables return rubbish. Offcourse it does, no problem there either. - But if I declare People[49] globally, then everything works just fine. What is going on here? As far as I know the code presented above shoudl work nicely. Nevermind my skills in file I/O. Just learning. Unless it is related to the exception error. Thank you all, Val Tag: string Tag: 222129

    - How to recycle codes for ActiveX project? I need to develope a different version of ActiveX which shares 90% codes with an ActiveX project I completed a while ago so I would like to recycle as much source codes as possible. My old ActiveX project was started on VC++'s ActiveWizard. I thought I could simply create a new project so that I have an unique UUIDs, then copy the .odl file to the old project, and modify some names in .cpp files. When I did that, the project builds fine, but it won't register. Any suggestion how to recycle sources in such case? Thanks! . Tag: string Tag: 222127

    - overloaded operator Hi All, Suppose I have a class of my own, CVCEditBox and I overload a few operators like this: class CVCEditBox : public CStatic { .... CVCEditBox operator+ (const CVCEditBox& TheString) const; ... } And then, the implementation of this operator would be: CVCEditBox CVCEditBox::operator+(const CVCEditBox& TheString) const { return CVCEditBox((CString) SomeString); } By the way, I do have an argument constructor that takes a CString.. The question is, is there any problem if I do the overloading this way ? [returning the constructor of the object] It seems to work but I am wondering if I should do it differently (maybe a more efficient way .. it seems to me that returning the constructor rathern than a combination of *this / CVCEditBox& uses more memory since it does a copy/create a new object ?!] Thanks in advance, Marius Tag: string Tag: 222109

    - Template member functions syntax Hi. Does anybody can help me understand the syntax for defining members templates out of classes (please see below an example)? Thanks Regards. Fabio *************************************************** The following compiles and runs fine. template <int N> struct X { template <int M> int foo( int z ) { return M+N+z; }; }; int testTemplate( int z ) { X<4> x; return x.foo<5>( z); } However, I would like to define the body of foo outside the class declaration. Do you know what is the syntax to do that? I have tried many different possibilities, but the compiler (VC7) doesn't like any of them. For example, this doesn't work... template <int N> struct X { template <int M> int foo( int z );// { return M+N+z; }; }; template <int N> template <int M> int X<N>::foo<M>( int z ) { return M*N*z; } int __cdecl main(int argc, char* argv[]) { int y = X<4>().foo<5>( 10); return y; } Tag: string Tag: 222096

    - CFile class newbie question - file handle invalid? Hi I've got the following code for the constructor of a class that I've derived from CFile. It is in a project that I've created using ATL COM AppWizard, with MFC support. So it's using ATL *and* MFC. However when I try to write to the file, it asserts in the first line of the CFile::Write class, on the line: ASSERT (m_hFile != hFileNull) so I decided to put this test in my own class so I could check for it - my code is as follows: CBMPFileInternal::CBMPFileInternal(LPCTSTR lpszFilename) { try { CFile::CFile(lpszFilename, CFile::modeCreate | CFile::modeWrite | CFile::typeBinary); if(m_hFile != hFileNull) OpenedOK = true; else OpenedOK = false; //<-this occurs. } catch(CFileException e) { afxDump << "File could not be opened " << e.m_cause << "\n"; OpenedOK = false; } } However I checked in windows explorer and the file IS being created. How can I get the file handle to be non- null, and thus enable writing to the file? thanks Tag: string Tag: 222055

    - Inheriting from a DLL Greetings, I'm using VC 5 SP3 and I'm attempting to inherit a class from a DLL and call it's member function from an application (which links to the DLL). Base Class (inside of DLL) | Child Class (inside of application) The class within the DLL has been exported using: __declspec(dllexport) The application imports the class using: __declspec(dllimport) The DLL contains one member function: void CDllTest::SayHello() { printf("Hello C++!"); } All I want to do is call CDllTest::SayHello() from a Child class. However, the compiler error I receive is: DllTestApp\CDllTestChild.h(27) : error C2065: 'SayHello' : undeclared identifier I think this can be done but the syntax/mechanism to achieve it has eluded me. The source code is listed below. Can someone help? Here's the source for the DLL: // "DllTest.h" class __declspec(dllexport) CDllTest { public: CDllTest(){} ~CDllTest(){} public: void SayHello(); }; // DllTest.cpp #include "stdafx.h" #include "DllTest.h" BOOL APIENTRY DllMain( HANDLE hModule, DWORD ul_reason_for_call, LPVOID lpReserved) { switch (ul_reason_for_call) { case DLL_PROCESS_ATTACH: case DLL_THREAD_ATTACH: case DLL_THREAD_DETACH: case DLL_PROCESS_DETACH: break; } return TRUE; } void CDllTest::SayHello() { printf("Hello C++!"); } Here's the code for the child class that wants to inherit CDllTest. // CDllTestChild.h #include "DllTest.h" class __declspec(dllimport) CDLLTest {}; class CDllTestChild:public CDLLTest { public: void SayHelloChild() { SayHello(); // ** error C2065 ** printf( "Hello C++ Child!\n" ); } }; // here's the code for the application // DllTestApp.cpp #include "stdafx.h" #include "CDllTestChild.h" int main(int argc, char* argv[]) { CDllTestChild dtChild; dtChild.SayHelloChild(); return 0; } Thank you, Roy Tag: string Tag: 222047

    - Multiple CDynLinkLibrary in DllMain proc and other location Hi, I've got some MFC extensions DLL from which I have removed the multiple resources. I localize the resources into separated resources-only DLL because of the difficulty to deal with the language resources load order. The problem is that I must ensure a backward compatibility with the old clients EXE. Indeed these assume to the DLL find out itself its resources; i.e a default behaviour. I code this like (from my extension dll): AFX_EXTENSION_MODULE extDLL; DllMain(...) { .... AfxInitExtensionModule(extDLL); extDLL.hResource = AfxLoadLibrary( default resource); new CDynLinkLibrary(extDLL); .... } Now for the new clients, I want to supply an exported function InitMyDLLResources() where I would to replace the default loaded library with a new convenient one. I code like (from my extension dll): InitMyDLLResources( the language) { AfxTermExtensionModule(); AfxFreeLibrary(extDLL.hResource); AfxInitEXtensionModule(extDLL); extDLL.hResource = AfxLoadLibrary( convenient resource); new CDynLinkLibrary(extDLL); } Invocation from old clients EXE: nothing. Invocation from new clients EXE: CWinApp::InitInstance(){...InitMyDLLResources(the language);...} This stuff seems to be functionnal but I don't really have a wide kwnowledge about the AFX_EXTENSION_MODULE and the CDynLinkLibray so I would like to know if all of this is not savage. My doubt carries on the safe manner or not to proceed like this ; quality of design is another problem :-) (but in a first step, safety is more important for me) Thanks you very much for your advise Manfred Ehrhart Tag: string Tag: 221996

    - How to find EOF in buffer received from socket? Hi, I use recv() to get data buffer and write to file. The other side uses TransmitFile() to send data. How should I decide in recv() if all the sent data have been received? Can I search for EOF at the end of each received buffer? I tried if(fBuf[nRecv-1] == EOF) (and fBuf[nRecv]) but it didn't work. The sample send and receive code is as following: ////send data: -------------- .... hFile = CreateFileA( fname, GENERIC_READ, 0, NULL, OPEN_EXISTING, FILE_FLAG_SEQUENTIAL_SCAN, 0 ); .... TransmitFile( socket, hFile, 0, 0, NULL, NULL, 0 ); .... ////receive data: ... hFile = CreateFileA( fname, GENERIC_WRITE, 0, NULL, OPEN_ALWAYS, FILE_FLAG_SEQUENTIAL_SCAN, 0 ); ... while(true)//find better way to exit the loop? { TCHAR fBuf[1024]; nRecv = recv(sock, (LPSTR)fBuf, sizeof(fBuf), 0); // if(fBuf[nRecv-1] == EOF) break; -- not working .... WriteFile(hFile, fBuf, nRecv, &dwWritten, NULL); } .... I used to use send file size first, and use the size to exit the while() loop. But I need to process the received buffer after file size, since that will be the file data, and that processing affects some of the binary files' format, so they can't be opened in after transfering. It will be 'cleaner' if I can avoid sending/receiving file size and exit the while() loop by detecting EOF, or other ways to check the complete of receive.

Here's my situation: I need to capture URL Requests (clicks or address bar entries) and if it matches a specific URL like "http://somedomain.com/blorg.exe" I want to be able to intercept that and tell IE i'll take care of it myself, OR, if it does not pass my criteria, let IE handle the click. I DO NOT want to register my own protocol like mark://somedomain.com/.... I need to be able to look at the whole URL This is what I've done so far: I have created a namespacehandler in the HKCR area so my DLL gets called for any URL's requested in IE. My DLL gets called and the start() gets called, but if I don't want the URL, I'm returning INET_E_USE_DEFAULT_PROTOCOLHANDLER. This causes IE to crash. But if I return S_FALSE, IE stops navigation and stays where its at (what I want when I want to handle the URL myself). Thanks in advance.. Tag: string Tag: 221981

    - Templated operator overloaded friend function Hi All, I have some code that used to work in VC6, but the stricter VC.NET isn't allowing to compile. Here's a reproduction of the code... template class<T> _DLLExport class MyString { ... public: friend _DLLExport MyString<T> operator + (const MyString<T>& s1, const T * s2); ... }; template<class T> MyString<T> operator + (const MyString<T>& s1, const T * s2) { ... } This now fails with an unresolved external for the operator + function... Looking at the help, it claims that this problem can be fixed by defining the friend as a specialzation of the template function: friend _DLLExport MyString<T> operator + <T> (const MyString<T>& s1, const T * s2); or friend _DLLExport MyString<T> (operator +)<T> (const MyString<T>& s1, const T * s2); But these both fail with compilation errors. Has anyone got any ideas what I am doing wrong? Thanks, Otto Tag: string Tag: 221956

    - File transfer question again ... Hi, I am implementing client/server programms using winsock to do file transfer. Now I have 'put' and 'get' functions. I have GetFile() and PutFile() functions, GetFile() will get file data from socket and write to destination fiile; PutFile() will read source file data and use winsock TransmitFile() call to write to socket. Now I am testing the client/server with a setup.bmp file with two PCs, pc1 and pc2, both running on w2k. I switch the pcs to be client/server. When client 'put' a file, it sends 'put' command to server (which triggers server to call GetFile()), and then call PutFile(). When Client 'get' a file, it sends 'get' command to server (which triggers server to call PutFile ()), and then call GetFile(). The problem is that the 'put' function works, but 'get' not. Here works means 1) the setup.bmp file can be viewd (or opened) using MS Paint; 2) pc1 and pc2 both work when switched as client/server; not working means when I try to open the transferred file, I got the MS Paint error "There is not enough memory or resources to complete the operation. Choose some programs, and try again". The transferred file size is correct (no error during transfering for either 'put' or 'get'), and 'get' calls the same functions (GetFile() and PutFile()) as 'put' does. I don't understand why 'put' works but not 'get'? Any help is really appreciated. Thanks, Peter Tag: string Tag: 221927

According to this article is appears that .NET will be the native api of LongHorn. http://zdnet.com.com/2100-1107_2-5101117.html Can some knowledgeable person confirm/deny this? I have seen statements on various newsgroups that the Win32/64 API will simply be an emulation on top of the .NET API. True? -d Tag: string Tag: 221924

    - Using MFC in a Managed C++ DLL?? Can I? I have some old C code that uses MFC and some C Run Time Library. I need to be able to call this from C# I thought i'd be able to create a Managed C++ DLL, tell the project it was using MFC, include the .c file and be on my way. Can I use MFC in a Managed C++ DLL? If I build a Visual C++ Class Library (.Net) and tell it to use MFC in a Shared DLL I immediately get the following warning nochkclr.obj : warning LNK4099: PDB 'libc.pdb' was not found with 'C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\lib\nochkclr.obj' or at 'C:\BlueIguana\SymbolPDTSolution\Debug\libc.pdb'; linking object as if no debug info This is before I've typed any code. linking with old run time library things because of the use of things like strupr in the C code? I was hoping I'd build a simple C++ class (2 methods), that would call into this C code and that these methods would be available to my C# code here is what I need to do I have three files.....a LARGE .C file and a good sized .CPP/.h file. I don't have time to port these 1000s of lines of code. These files are actually being called from an C++/MFC application (which I can build and run) but I don't need ANY of the UI that is calling this C code It's sort of strange how this project is set up, but in this MFC app, there is a CPP file with two lines in it, and include of stdafx.h and a include of the above mentioned .C file. I need to call this C code form C#. The C code uses both MFC and run time library calls. Can I do this with a Managed C++ DLL? thanks mike Tag: string Tag: 221920
