    - partitions Hi I partitioned my hard disk into 3 primary partitions, 1 extended partition with 2 logical partitions. The list of all partitions from diskpart (or from disk management MMC) is the following: Partition 1 - Primar Partition 2 - Primar Partition 3 - Extende Partition 4 - Logica Partition 5 - Logica Partition 6 - Primar I write a C++ tool to get the position of the last primary partition (in the example above is #6) using IOCTL_DISK_GET_DRIVE_LAYOUT_EX. However, when I iterate the partitions (PARTITION_INFORMATION_EX) in DRIVE_LAYOUT_INFORMATION_EX, it returns all the primary partitions first then the rests, i.e. partition 6 above becomes partition 3 Does anyone know why? Does primary partition takes higher precedence than extended/logical partition? IOCTL_DISK_GET_DRIVE_LAYOUT_EX should return an exact layout of the partition in the drive as it's shown in either diskpart or disk management MMC, should it not Please help, thanks -Paul Tag: how do you reference a static library?

    - Looking for best practices in designing a form and retrieving values Hello. I've been designing forms in VC++ 6.0 for a little while now. But I have a nagging question about best practices in retrieving the data from the form. I am just now starting to use data exchange, which reduces the code I needed, but I still don't know if it is best to allow the data from the form to be public and easily accessible, or if I should write set and retrieve functions within the form. Noone else is using the form so hiding data isn't necessary. Are there any other considerations that I might take into account in making public variables or private variables with accessor functions? Thanks in advance. -- Ryan Taylor rtaylor@stgeorgeconsulting.com Tag: how do you reference a static library? Tag: 229922

    - Delete all files with "a pattern" Hi all, I would like to delete from a directory all the files that match: bar*.* I know that I could do for instance: system("del bar*.*"), but this will bring up the command prompt window and as my app is a winmain app this wouldn't be nice. I could use DeleteFile, but you can not use wildcards in this one. How could I do this using Windows functions? Thanks in advance, Viv Tag: how do you reference a static library? Tag: 229916

    - unhandled exception when using virtual destructor and new [0] Hi, I'm using VC++ 6.0 (SP 5) and noticed this behavior: Basically it comes down to this example: // Class with virtual destructor class CMyClass { public: CMyClass() {} virtual ~CMyClass(){} }; int main(int argc, char* argv[]) { int iSize = 0; // Normally comes from some function where 0 is possible CMyClass *poMyArray = new CMyClass [iSize]; for (int i=0; i<iSize; i++) { // Do some calculation... } delete [] poMyArray; // --> Unhandled exception in prog.exe: 0xC0000005: Access Violation return 0; } If I make the destructor non-virtual everyhing is fine. I've looked at some previous posts around this issue and some suggested it to be a compiler bug. If this was a compiler bug, has this been resolved in SP6 or is this a good reason to upgrade to Visual Studio.NET ? Best regards, Colin B. Tag: how do you reference a static library? Tag: 229911

The error appears in assert calls. This is really annoying. How many symbols are allowed? Can this be changed with some compiler option? Ok, i guess I have lots of symbols caused be some heavy template use but the suggested solutions in the help are not possible for me without some major refactoring. Any other possible solutions?

    - Help. We have created an activex Ctrl using MFC. It has serialize method in its COleControl derived class. Now myActiveX control is inserted in a powerpoint presentation. Whenever power point slideshow ends, then the serialize method is getting called. How to avoid serialize method is getting called at the end of slide show mode or slide changes? I am trying by setting SetModifiedFlag(false) but no result. Note: I want use serialize method for other scene like saving PPT file. I dont want to get serailze only at the end of slide show or slide changes. Also I dont want to try this way, bcos this will stops serialize with other scenarios like saving in presistance control in MS-word and Powerpoint CMyOleControl::DoPropExcahnge() { if(pPX -> IsLoading()) COleControl::DoPropExcahnge(pPX); } Please suggest.

    - return value of += operator (probably an easy q for somebody) Consider the following small program #include <stdio.h #define printvars printf("a = %d, b = %d, c = %d\n", a, b, c) int main( int a = 1, b = 2, c = 3 printvar int x = a + (b += 3) printf("x = %d\n", x) printvar return 0 on line 3, I'm saying I want the variable b to be incremented by 3, and then the result added to a and the result of that stored in x But is it according to the C++ standard that the expression '(b += 3)' should actually RETURN 'b+3' aswell as just doing the action of incrementing 'b' by 3?

    - 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.

    - 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: how do you reference a static library? Tag: 229801

    - 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).

How do I keep track if the child process has launched another process? Is there a process Group ID (like in UNIX) I can use? Thank you very much. Paul Tag: how do you reference a static library?

    - C1010 looking for precompiled header Using VC6, all at once I've started to get C1010 errors for each of the 5 C files mixed in with my many C++ files. The errors say: "unexpected end of file while looking for precompiled header directive" What is a precompiled header directive, and what might I have done to start getting these messages? (The explanation given in the MSDN library didn't help much.) Thanks, E-Jo Tag: how do you reference a static library? Tag: 229745

    - 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: how do you reference a static library? 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: how do you reference a static library?

    - How do you use a derived CListCtrl in a dialog based MFC application? I have derived a class from CListCtrl in a dialog based app. I want to be able to use alternating colors for rows. When I use the designer, I create a ListView that I can access using GetDlgItem(the_id). If I use m_pListCtrl = (CMyListCtrl *) GetDlgItem(IDC_LIST); the constructor does not get called, and none of the overridden methods get called, because the object already has been constructed before I make the assignment. How do I get the dialog to use my CMyListCtrl when the ListView is constructed? Is it even possible to use the designer when doing this? Thanks. AU Tag: how do you reference a static library?

    - anonymous structs and unions I tried to put an anonymous struct inside an anonymous union. Unfortunately, this does not work. 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: how do you reference a static library?

    - 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: how do you reference a static library?

I've generated a static library and this generates .obj and .lib files. As I
understood it, the .Lib is used in identifying what the library contains?
however, it seems rather large and therefore I guess it IS the library. What
purpose therefore are the obj files?

So I guess my first question is - what is a "static library"

The next one, how does this differ from a DLL?

TO use the static library, I imagined that I would just ensure the C++
Directories setting includes the directory that holds the .LIB file? This
doesn't seem to work!

Any guidance will be greatly appreciated.

Thanks

John

A static library is a collection of compiled code that get's pulled into
projects that link to it. Not all code is pulled into the project, only
code that is referenced.

DLLs are also a collection of compiled code. The main difference is the
project linked against a DLLs import library only maintains entry point
pointers and when needed the DLL supplies the requested entry point.

You must also add the name of the library on the link tab of the project
settings.
