    - How can VC build a cpp file not in a project? I'm working with VC++ 7, but I think this rather dumb question is C++ related rather than Vis Studio related. I am trying to use log4cpp, and I downloaded the zip files. When I wish to use it in my code I can #include the required header file. However, when I build I get link problems. This is because the cpp files are not being found or compiled. I can tell VS to look in the correct folder for the cpp, but that's not enough (C++ Directories). Am I missing something here? I don't see why I should expect the compiler to compile these library files but I do. Should I compile them as a separate project do you think? I must say that I don't understand pre-compiled headers either - is this something I should be looking at! I know this is Vis Studio biased, but the problem is that there's a general principle I don't understand. Can you help? Please excuse the extreme stupidity of this post. Thanks very much. john -- --- If you need to reply personally, append "text" to the domain name in my email adr. Thanks Tag: Compile question Tag: 229880

    - Are there sites to remotely test very small pieces of C++ on cross platforms in case MS' C++/ specs are suspicious? In case of failures by MS's VC++ 7.1, and in order to get a better sense whether it is the compiler or C++ specifications (which I am mostly suspecious of), I would like to try it on different platforms. I am talking of course in cases the compilation+linking passes succesfully (on MS (and Borland C++BuilderX)) and the output is unacceptable. I am sure (99.99%,... I must leave room to an error on my part...) that the problem is either in the compiler and / or the C++ standard specifications. For example, in one case, ALL the program does is outputing typeid(s) of pointers of 3 instanciated templates where some of the pointers members point to objects that have not been even declared at all... at the expense of missing pointers types to object that have been instanciated. Could not go much wrong with such a program. For commercial reasons, I am not at liberty to publish the code. Thanks in advance. Tag: Compile question Tag: 229801

However in Borland C++ Builder this construction allows me to see them. I can't realize how to implement the same ability in MS Visual C++. I don't want to write long tricky and looking weird things to get around this restriction to assign only STATIC functions pointers to variables like my FOnEven* OnEvent; Does anyone know some general solution? I wish there was a tickbox in settings to say "Allow assign NOT STATIC member functions to CALLBACKs" } ==================================================== Tag: Compile question Tag: 229795

    - Are the but standard C++ functions such as itoa(int,char*) supported or not??? itoa(int,char*) is still a standard c++ function. Yet, the documentation of Visual Studio .Net 2003 does not show it in any normal way - it is mentioned as "side effects" in 4 results search but does not specify the required include file. If I use the global resolution symbol ::itoa(int,char*) it does not deny the function altogether but claims that the function does not take 2 arguments (rather than telling me how many it is expected). Anybody knows what is going on with this group of old C functions? Thanks Tag: Compile question Tag: 229774

    - How to get text from message WM_SETTEXT, etc Hi. I'm trying to trap WM_SETTEXT messages using system hooks and all seems to be going well with the hooking process (i.e. I get the messages and they correspond to the same messages I see in Spy++,) but for the life of me I cant figure out how to get at the string: "lParam - Pointer to a null-terminated string that is the window text." All attempts to strlen(lParam) or strcpy(lParam) just cause havoc. I regularly work with the .NET framework, but most of my C/C++ experience is very rusty and was very unix-centric to begin with. I'm assuming that I'm missing something here, like having to marshal the string across processes (the messages are being snatched from another process) or having to envelope the whole copying affair in a critical section or perhaps even just using different APIs than the good ol' stdio.h stuff. Can anyone shed any light on this for me? It seems like "getting the text" from a message should be a fairly straightforward task. Thanks, Ian Tag: Compile question Tag: 229743

    - /clr option and CFileDialog Hi: I have added /clr option to my application, because I am working about the specific culture in order to be able to load the appropiate only-resource dll. But I have got a new problem, and I think is not directly related with the problem of the specific culture, else with a new problem with the using of CFileDialog. If I don´t use /clr option, my dialogs (CFileDialog) work fine, but if I put that option, when I lunch a CFileDialog, it shows files associated to my default extension, but if I selected any other extension, the files view is blank. The only way to see the associated files is changing the current folder. When I modify the folder (I go out, or I go back again to the default u other folder ) I see again files associated to the required extension. I don´t understand what is happened, because if I clean the /clr option my dialogs are fine again. Here is an example of one of my dialogs: CFileDialog *dlg = new CFileDialog(TRUE, "bmp", NULL, OFN_HIDEREADONLY|OFN_NOCHANGEDIR|OFN_EXPLORER|OFN_FILEMUSTEXIST|OFN_SHOWHELP , "MyApp Files (*.mtc)|*.mtc|Bitmap Files (*.bmp)|*.bmp|All Files (*.*)|*.*||"); Perhaps I have to change any other compiler option?

    - unicode I was wondering if anybody could advise me on unicode issues I have an application which consists of a C# program, that calls a unmanaged C++ DLL The details are as follows Environment: MSVS.NET 2k3, WinXP Pr Unmanaged C++ DLL _UNICODE defined Uses _TCHAR* for strings, and _tcs~ functions for string manipulation Uses _T("textconst") for text constants mixed debugging mode (to allow stepping into it Managed C# program Consists of one winforms control and one winforms project both have the same debug settings (allow unmanaged debugging) The DllImport interface to the C++ DLL calls it using [CharSet = CharSet.Auto and the string parameter is passed wit [MarshalAs(UnmanagedType.LPTStr)] From what it says in the documentation, it seems that by using UnmanagedType.LPTSt in the DllImport section, the operating system will decide automatically whether t marshal the string arguments as unicode or not. This is great if I just want my progra to work, but not if I want to understand what is going on with all this unicode stuff If somebody can try and understand the following questions and lend a hand t clear my understanding I'd be very grateful Will the .NET framework's interop marshal the C# calls to the DLL as unicode because the DL is unicode, or will it be because the operating system is XP On, say, a Win98 OS, which of the following are true - the DLL wouldn't compile unless unicode was turned of - the DLL would compile if unicode was kept on, but would produce garbage - the program (as compiled on XP with unicode on) wouldn't ru - the program (as compiled on XP with unicode on) would run, but characters 128-255 wouldn't be available On a computer with, say, NT/2000/XP OS, which of the following are true - the program (as compiled on XP with unicode on) would be faster than if unicode was of - the program (specifically the DLL) wouldn't be able to process characters 128-255 i unicode was turned off When I say 'if unicode was turned off' I mean the setting to switch the _UNICODE fla off correctly set in the compiler properties before compiling the DLL I notice that when I do this, sizeof(_TCHAR) = 1 and when it's on, sizeof(_TCHAR) is 2 I understand this (almost). But I'm lost when it comes to differences between different OSes And why do unicode characters take 2 bytes, when 1 - 255 can be fit in one Thank Tag: Compile question Tag: 229725

With the complete code example below, I get the compiler error: error C2039: 'f1' : is not a member of 'dataElement' I can't think of any other way to define this type of structure. Basically, I want to be able to access a 32-bit integer in multiple ways, either as a full integer or broken out into bit fields, using the simplest notation possible. Actually, I'd much prefer not using an anonymous struct because these are Microsoft-specific. Anyone have any ideas? For the example below, the simplest notation would be: deTemp.f1 deTemp.f2 deTemp.dwAllData // ---------------------------- BEGIN CODE #include "stdafx.h" using namespace std; struct t_fields { unsigned __int16 f1 : 16; unsigned __int16 f2 : 16; }; class dataElement { public: union { // anonymous union unsigned __int32 dwAllData; struct t_fields; // anonymous struct }; }; int _tmain(int argc, _TCHAR* argv[]) { class dataElement deTemp; cout << "size is: " << sizeof(class dataElement) << "\n"; deTemp.f1 = 1000; return 0; } // ---------------------------- END CODE Tag: Compile question Tag: 229703

    - Uninitialized variables warning Hi, Though the compiler warns you of using uninitialized variables in many places, those warnings are not always shown, consider this program: #include <stdio.h> class X { public: int i; int& r; X() : r(r) // <- typo #1 { i = 27; } }; void main() { X x; int i = 28; int& r = r; // <- typo #2 printf("%d %d %d %d",x.i,x.r,i,r); } Typo #2 is detected by VC6, VC2K2, 2K3 and by the 2K5 Preview, but typo #1 is not spotted by any of these compilers, the program just crashes.

    - Why unwanted image is shown in the 1st column of CListCtrl? Hi: I'm using a CListCtrl and need to set an image for a sub-item (LVS_EX_SUBITEMIMAGES is enabled). But I noticed that as long as the SetImageList() is called, the image will show un-expectly for all items in the 1st column. When the 1st column is inserted, only lvi.mask = LVIF_TEXT | LVIF_PARAM is specified, there is no image here. Not sure what is going on. Below is the code to create the CImageList. Any thought is appreciated. // create the image list CImageList* pi = new CImageList(); pi->Create (IDB_BITMAP1, 60, 0 , RGB(255,255,255)); lc.SetImageList (pi, LVSIL_SMALL); // lc is the list control Thanks Polaris Tag: Compile question Tag: 229699

    - MSVC build on dual CPU machine I noticed that when I build a project on my dual CPU machine then only one processor is loaded (more precisely - both of them ~50% loaded) Is it possible to configure MSVC to take advantage of both processors? This would lead to 2X speed up. Has anyone managed to handle this problem? There might exist 3rd party tools which can do it. CHK Tag: Compile question Tag: 229684

    - CreateProcess question Hi, I am trying to write an application that will launch a second application using CreateProcess... SECURITY_ATTRIBUTES sa; STARTUPINFO si; PROCESS_INFORMATION pi; ::ZeroMemory( &sa, sizeof(sa) ); sa.nLength = sizeof(sa); sa.lpSecurityDescriptor = NULL; sa.bInheritHandle = TRUE; ::ZeroMemory( &si, sizeof(si) ); si.cb = sizeof(si); ::ZeroMemory( &pi, sizeof(pi) ); // Start the child process. if ( !CreateProcess( NULL, "C:\\second_app.exe", &sa, &sa, TRUE, 0, NULL, "C:\\", &si, &pi ) ) { return; } What I want to do is monitor the second process for file read/write, in other words if the second application interacts with the file system at all, I want to know how and where, and place that information into a log file. I know CreateProcess gives me... pi.dwProcessId pi.dwThreadId pi.hProcess pi.hThread How can I do this? Any suggestions, ideas are greatly appreciated. Thanks, Kal Tag: Compile question Tag: 229662

    - any training available on configuring VS & VC++ I'm looking to get some training in how to configure Visual Studio & Visual C++. We know C++ fairly well (migrating from a Sun environment), we don't understand configuration issues and this is becoming a stumbling block. We have an SDK that doesn't use namespaces to isolate things, we have other libraries that do have namespaces that end up with conflicts with the purchased SDK. I'm sure there are ways to resolve these issues, but they require someone who understands more of the in's and out's of configuration issues that are eluding us. We are trying to add some software engineering methodologies to this such as using CPPUnit that fail when linking with the SDK. There are things like how the syntax editor can be set to recognize non-CPP file extensions as C++ syntax and have it "stick". How a project workspace and a project work together - we have a project where the various checkboxes and menu items say "use multi-threaded library - /MT" but the PLG file shows /MD and then the compiler issues warnings about needing to use the DLL version of the libraries. I checked with Learning Tree and they tried to sell me a course on Crystal Reports, obviously there is a keyword match in there somewhere, but that probably wouldn't help much. I would like to say that we could accumulate this gradually, but we have been struggling with this for months and have made little progress. I've been following this newsgroup for the past several months, and while it's been occasionally useful, I think most of these problems are too weird for a forum such as this. -- Take care | This clown speaks for himself, his job doesn't Wayne D. | pay for this, etc. (directly anyway) Tag: Compile question Tag: 229648

    - InterlockedIncrement Given an instance of int, i, is the bare C++ increment/decrement operator on i atomic? int i = 0; i++; i--; I guess these operations are translated into corespondent single machine instructions.

If I were to build a COM class, is it a must to use InterlockedIncrement/InterlockedDecrement in preference to ++ and -- operators? Ben Tag: Compile question Tag: 229641

Yes, course it can. But you've got to make sure you select the right
option. It'll try and have you create a .NET application if it can.
