    - worker thread slowed by MFC UI interactions I haven't manually invalidated the view or coustomized its ondraw function. I just create a 3D engine renderer(Ogre 3D engine) in the worker thread and give the HWND of the view to it. Then call the 3D engine's method "renderOneFrame" in the loop of the worker thread. I guess the engine do the video buffer swapping job in the "renderOneFrame" method. I tried capturing and handling WM_ENTERSIZEMOVE and WM_MOVING messages in the program. But failed to improve the perfomence. Tag: Visual C++ General How to judge the attribute of the folder Visual C++

    - MFC and CLR - Attempt to load an unverifiable executable with fixups As I said, I think the regasm is superfluous. You could try to run the exe and see if it works. The batch file looks like the step comes from the IDE. There is a settings "Register Output" under "Linker"->"General". You should just uncheck it and see if that does the trick. BTW: The linker warnings are not related but you should probably look into tehm anyway. LNK4098 is almost always an indicator for something bad going on (BTW: /clr implies /MD which might the root of that problem). -hg Tag: Visual C++ General How to judge the attribute of the folder Visual C++

    - Frustrating Error - error C2259: cannot instantiate abstract class The Error error C2259: 'SphereEntity' : cannot instantiate abstract class 1> due to following members: 1> 'void Entity::render(G3D::RenderDevice *) const' : is abstract 1> : see declaration of 'Entity::render' 1> 'G3D::RealTime Entity::getIntersectionTime(const G3D::Ray &) const' : is abstract 1> : see declaration of 'Entity::getIntersectionTime' SphereEntity is a declared as a subclass of Entity. Entity is an abstract class with two functions: render and getIntersectionTime. These two purely virtual functions of Entity were implemented in the SphereEntity class. I receive the error when I try to create an object of SphereEntity. Any help would be appreciated.

    - To read the sentence as a whole(single argument) from command-line arguments Your final option is to just parse the command line to its full length, and add words to a whitespace separated string. Code Snippet #include <string> #include <sstream> #include <iostream> using namespace std; int main(int argc, char* argv[]) { int number = atoi(argv[1]); // parse number string description; for(int i = 2; i < argc; ++i) { if(i > 2) description += ' '; // add whitespace for each appended word description += argv[i]; // add the next word } } Tag: Visual C++ General How to judge the attribute of the folder Visual C++

    - syntax of .vcproj files Probably because someone entered it like that in the IDE It's quite easy to accidently modify settings for a particular configuration only, even though you actually wanted to do it for all configs (and maybe platforms). I don't think there's any direct documentation on the format, but I take it the IDE folks simply take advantage of .NET reflection-based XML persistence. So you can take a look at the Project Model API and get pretty decent idea about the XML format, too. -hg Tag: Visual C++ General How to judge the attribute of the folder Visual C++

    - Copy constructor? For this you overload the operator = member function. In the MSDN it says that you create a function like this. MyClass^ operator = (MyClass^ param); It would then be declared something like this. MyClass^ MyClass: perator =(MyClass^ param) { MyClass^ tmpClass = gcnew MyClass(); //put all of the stuff from the old class into the new class return tmpClass; } If you define a constructor to take a MyClass^ then you can also make that simpler by doing it like. MyClass^ MyClass: perator =(MyClass^ param) { return gcnew MyClass(param); } Tag: Visual C++ General How to judge the attribute of the folder Visual C++

    - List Box Hi, so you are using the Express edition: I'm sorry, but I think that the Express edition does neither support MFC nor ATL. However, you could use the pure Win32 SDK API, as you have installed the PSDK... If you are using WinForms, as I understand from your post: if I were using C# I would add the new item to the listbox .Items collection, using the .Add method, e.g.: myListBox.Items.Add( "the string..." ); But I've never done C++/CLI. I don't know the C++/CLI syntax, maybe it could be something like myListBox->Items->Add( ... ) ... Giovanni Tag: Visual C++ General How to judge the attribute of the folder Visual C++

    - Structure Alignment/Packing issue Since you've got alignment / packing in the topic, I suppose you're already aware of the settings found in the project properties to control default struct alignment for the compilation. In addition to that, there's the pack pragma Sam suggests, and a third alternative through the align declspec. In either case, I suppose this is rather a case of order inconsistency than the actual packing, seeing as it used to work until you changed one of the applications slightly.

    - Problem with CString Variable It also can appears when using uninitialized variable. For example, the following code samples yield the same error message: void proc1_name() { int a; funct2(&a); // it crashes } int proc2_name() { int a; return a;// it crashes } // this sample demonstates array boundary exceeding void proc3_name() { int arr[2]; arr[0] = 1; arr[1] = 2; arr[2] = 3; // on return you will get stack corruption } ___________________________________________________ Best regards, Alexander Stoyan E-mail: alexander.stoyan@gmail.com MSN: alexander.stoyan@gmail.com ICQ: 295663150 Tag: Visual C++ General How to judge the attribute of the folder Visual C++

    - Constructors for global variables are not called??? AFAICT, that's not a bug but it is the way all significant linkers work and have ever worked. Object files are selected from an archive, if and only if they are required to satisfy a strong symbol reference (via the archive symbol table). The unreferenced COMDAT elimination phase runs logically after that (even though a smarter linker will probably construct the dependency graph earlier). While, an implementation may defer construction VC does not. Rather, the compiler injects pointers to generated initialization functions for objects with nontrivial constructors or destructors or those requiring dynamic initialization. These pointers are emitted into a special section -- typically, .crt$xcu. If the containing object file is selected the input section from that object file will contribute to the corresponding output section (It's not a COMDAT section). The CRT initialization invokes the initializers before entering the user supplied main function. The /VERBOSE linker switch will reveal why a particular object file is selected from a library or not. Of course, you should really be certain that the initializers are not called. For instance, the debugger can't materialize a breakpoint on a given code line if the containing translation unit was not built with debug information enabled. -hg Tag: Visual C++ General How to judge the attribute of the folder Visual C++

    - ActiveX on Vista Hi We have application which is launched by Activex and works fine on Windows XP - but we are having problems with this on Vista. We have looked at many MSDN articles which suggest using manifest files. We have implemented manifest in resource section of correct .exe file using MSVS. We have also read some articles regarding the use of MT.exe tool (v5) from the Vista SDK to embedd the manifest file, which seems to complete the embedding process ok. Using this example from MSDN:- <trustInfo xmlns="urnchemas-microsoft-com:asm.v3"> <security> <requestedPrivileges> <requestedExecutionLevellevel="requireAdministrator" uiAccess="true"/>; </requestedPrivileges>; </security> </trustInfo> Unfortunately when the Activex is launched Windows Vista seems to ignore the manifest and copy the files from website to the virtualized folder and not the real folder. The real destination folder is "c:\users\%username%\documents\%appname%" - But the files keep being copied to the virtualised folder:- "c:\users\%username%\appdata\local\micrsoft\windows\temporary internet files\virtualized\c\users\%username%\documents\%appname%\" after copying files to the virtualized folder, the application attempts to launch but we get "Error Access Denied" and cannot launch. Also:- It seems that "manifest" files are for System folders and not user folders, so we are unsure why this is happening with the users profiles folders also. If files are manually copied to correct location, the application can be manually launched (but not from activex) Any help would be greatly appreciated to overcome this problem and get our application running from activex like it does successfully in windows xp.

    - CAnimateCtrl does not animate Hello! In my project on MFC I use the ADO library to get data from MSSQL. I want some dialog window to be displayed during long operation, such as executing any store procedure that download image from MSSQL. I try it in the following way: 1) Creating the modelles dialog with animate control 2) Executing the store procedure 3) Destroying the modelles dialog The fact is that CAnimateCtr in my modelles dialog doesn't animate in such operation. If I try to create such dialog in another way, for example, after button click, it animates OK.

hi everyone

Now i met the question that I cannot get the attribute of the Folder

I seted the folder read-only and tried

if((GetFileAttributes (folderpath) & FILE_ATTRIBUTE_READONLY) != 0)

{

MessageBox("readonly");

}

else

{

MessageBox("else");

}

And every time I got the message "esle",

Is there any other method to resolve the problem

Thanks a lot

try this

DWORD fa;
fa =GetFileAttributes("c:\\command.com");
if(fa & FILE_ATTRIBUTE_READONLY)

MessageBox("readonly");

else

MessageBox("else");

Thanx
