    - VS2005 SP1 Hell We upgraded to VS2005 SP1 and of course our code doesn't run now :-) We get the "app config is incorrect, etc.". Anyway, I think its because its not loading the right runtime libraries. So, we've updated our installation so that the SP1 runtime libraries get put in our app directory now. Problem is, its still loading the libraries from the SxS storage area. We really don't want to force every user to go run some other MS runtime install kit to be able to run our SW. So... the question is, how do we force our app to load the runtime libs from the app directory? This used to be a simple matter of putting all the right DLLs in your app directory. Whats the easiest way to do this? Tag: Displaying Graphs Tag: 279461

    - MD5 Hashing Hi there, Is it possible to create an MD5 hash of a series of bytes using the Crypto API? I'm presuming that the .NET Framework MD5CryptoServiceProvider merely wraps the win32 API. If so, does anyone have any examples of doing this? Many thanks in advance. Nick. Tag: Displaying Graphs Tag: 279451

    - multi-process singleton DLL I have a DLL that exports a class that allows a program to access a unique system resource. At the moment, the DLL is implemented as a singleton such that any thread in a given process is using the same resource handle. But, if a second, unrelated process loads the DLL and accesses it, this process will try to create its own handle to the resource which fails because it's already in use by the first process. How do I give the second process access to the handle that's being used by the first process so that both can query the resource? Thanks, PaulH Tag: Displaying Graphs Tag: 279412

    - Questions about VC++ Hi dear experts, I'm not experienced in VC++ but i have VC++ 6.0 just for a very few experience. I'm confused and i need to know someting about C++ application development under VC++ 6 or more. Here to go: 1-Is the most efficent way to develop GUI-based applications possible with MFC or what else? What's MFC used for? 2-What's the best way to learn VC++ or C++ with Windows app. developing? Which books? Web tutorials? There are some and a few free tutorials which are very fragmented and need to know which dicipline or procedure(s) is/are the most strong steps to learn VC++ ? I appreciate if you had useful steps till right now with your experiences. 3-When compared to Basic, VC++ or C++ seems much more complicated and has more mistake rist while coding, that's why i'm a bit concerned, so what are the basics understanding of Visual C++ enviroment/C++ ? (For example: Declarations, strings, using variables...) These can be generated more, so please post your feedback in order to undertand about VC++ coding disipline, recognizing enviroment and programming basics/tricks to make explicit things. Regards...

    - GETMESSAGE hook, WM_SYSCOMMAND, SC_CLOSE, and the "X" button? In an extension (DLL) to a subsystem:windows app I'm trying to make the app hard to close. A simple WH_GETMESSAGE hook correctly sees <WM_SYSCOMMAND, SC_CLOSE> when it's generated by the system menu's "Close" (also <Alt-F4>) and translates it into <WM_SYSCOMMAND, SC_MINIMIZE>. But my hook fails to see <WM_SYSCOMMAND, SC_CLOSE> when it was generated by the title bar's "X" button. The application does not set any other hooks. What's going on here? Can I work around it? Thanks. -- - Vince Tag: Displaying Graphs Tag: 279391

    - Instantiate Class with/without operator new? Hi, I'm trying to understand the difference between instantiating a generic C++ class, A) using operator new, B) not using operator new. I have a simple class called Numbers, that can add or multiply two ints supplied to the constructor. It seems to work regardless of whether I use new or not. I'm interested to know when I should use new for Class instantiation and when not to use it. I tried to find the answer by searching, but 'new' is not a very common word. Here's how my calling code looks in _tmain(), note one instance uses pointers, the other does not int a,b; Numbers * n1 = new Numbers(4,5); a = n1->Add(); wcout << a << endl; // prints 9 b = n1->Multiply(); wcout << b << endl; // prints 20 delete n1; Numbers n2 = Numbers(5,6); a = n2.Add(); wcout << a << endl; // prints 11 b = n2.Multiply(); wcout << b << endl; // prints 30 -- Gerry Hickman (London UK) Tag: Displaying Graphs Tag: 279369

    - How to check dll version? Hi, I have got a vc6.0 project from my coleague. There are many dlls in this project and export many functions. So in the main application, there are bunch of "GetProcAddrss". I don't this kind of style. I have a little knowledge of COM but do not have many experience, so I don't want to use COM. I want to export a class for every dll. The code like below: //public interface file class IHardwareInterface{ public: virtual DWORD GetHost()=0; virtual DWORD AddHost()=0; ... }; extern "C" __declsepc(dllexport) IHardwareInterface* CreateInstance(); //implement file class CHarewareImpl : public IHardwareInterface { ... }; Now, if in main application, I only need to create an interface for every dll. I don't have to write bunch of "GetProcAddess". If I want to add more export functions, I should update the interface class. What I worried about is if I use the old dll, main application will not report any errors when call "CreateInstance". It will report an error when I call the new function. Is there any method to check whether the dll is consistent with the interface file? Any advice is appreciated. Thanks in advanced. Tag: Displaying Graphs Tag: 279303

Several significant features included the TrueType font technology (which brought scaleable outline fonts to Windows), multimedia (sound and music), Object Linking and Embedding (OLE), and standardized common dialog boxes. Windows 3.1 ran only in protected mode and required a 286 or 386 processor with at least 1 MB of memory.

Hello, I have a global header file called TypeDefs.H, this file is included in header file of every class of my project. because all classes use custom types. Now I have a class called CMyData which is also a member of some structs in TypeDefs.H, so I have to include MyData.H in TypeDefs.H problem is some members of CMyData are custom and defined in TypeDefs.H so I also have to include TypeDefs.H in MyData.H I agree that it may seem ugly but in this way I can keep things organized in my brain, but compiler dose not like that and shouts loudly with thousands of error messages. I even tried to use <code> #ifndef MY_DATA_H_ #define MY_DATA_H_ ... #endif </code> in MyData.H and <code> #ifndef TYPE_DEFS_H_ #define TYPE_DEFS_H_ ... #endif </code> in TypeDefs.H but problem persists can someone kindly tell me how can I get over this problem:) Tag: Displaying Graphs Tag: 279231

Now I'm into a bit of C++ for writing a custom action for a DLL to be incorporated into an MSI installer. Yikes. What I'm basically doing is getting the Product Key from the MsiGetProperty() function, like this - TCHAR szPidKey[MAX_PATH]; DWORD dwPath; dwPath = sizeof(szPidKey) / sizeof(TCHAR); MsiGetProperty(hInstall, TEXT("PIDKEY"), szPidKey, &dwPath); So I have my Product ID in szPidKey. Now I want to do some manual verification of it. The Product ID is of the form - 123456789-ABCD-12 I need to verify this code so I need access to the beginning part (123456789) and the end part (12). So I'm looking for a way to substring out those parts of the string. I'm also looking to convert those substrings into integer or long data type so i can do some checking on them, is it ok to use itoa to do that? Thanks very much for any hints.

To display a graph i need a CFormView derived view window which gets
displayed on clicking View->Plot. Can u detail me out how i can do
this. I need to have the handler for ID_VIEW_PLOT in CFormView derived
class and not in CWinApp class. With your previous solution I am able
to create new windows. But now i want 2 type of view classes wherein
the form view opens only if i click the menu item.
Thanx in advance.

Rishabh
