    - memory problem i am creating controls like textbox, combobox and labels using new command on the class which I respectively derived from CEdit, CComboBox and CStatic and while closing of the screen I am deleting these controls using delete <controlname>. Now can someone tell me why is the memory as seen by the OS not coming down as it went up while drawing the screen. Hiding and showing screens will not help in my application as there will be around 30 to 40 screens all having more than 30 to 40 controls in each screen and my application is a MDI application so that the user can keep the screen open and go to some other screen. I also know that the memory is given to these controls from heap can someone suggest how to free the memory from the heap. I also notice that the destructor of each derived class is being called when I issue delete command. Also the screens destructor is called and even its parents like Document class's and childframe's destructors are called. Inspite of this the memory on the OS is not coming down and if all the screens are opened (20 to 30 screens) and then all are closed I can see around 50 to 60 MB of memory going high during opening of screen and during closing of screen only some 3 to 4 MB of memory is coming down. Thanks in advance. With these inputs of mine suggest me how to release memory consumed back to OS during closure of screen Tag: Visual C++ Language Unexpected namespace pollution in VC8 (bug?)

    - MFC ActiveX TLB File not found Hello... I am making a MFC ActiveX and when I try to register it with regsvr32 I get an error DllRegisterServer Failed. Return code was : 0x80020400. I've done some search and I found that I must call ::CoInitialize(NULL); I did this, but the result is the same. On a MSDN page I've read that When your control is registered, the AfxOleRegisterTypeLib function automatically looks for the specified .TLB file in the same directory as the control and registers it in the Windows registration database. If the .TLB file is not found, the function has no effect. I debug my I ActiveX and breakes at these lines : if (!AfxOleRegisterTypeLib(AfxGetInstanceHandle(), _tlid)) return ResultFromScode(SELFREG_E_TYPELIB); So, why can't I found the .TLB file Thanks Tag: Visual C++ Language Unexpected namespace pollution in VC8 (bug?)

This has to be programmed in a way that only default DynamicLinkLibrarys(.DLL) files are used. So I'm useing C++ and WIN32, working in Visual Studio 2005.

    - Managed Extensions for C++ to C++/CLI conversion tool We have just finished and released our 1st software project using Visual Studio 2005 MC++, the source code for this has magically turned into a deprecated syntax during the products development lifecycle.

For example we cant even add any new forms to our flagship software product with out hacking the project etc. Will you ever attempt to finish the Managed Extensions for C++ to C++/CLI conversion tool I have tried it out and it does not do anything usefull with our code at all : ( Can you offer services to take existing MC++ code and convert to the new Visual Studio 2005 SP1 C++/CLI syntax It seems you have very little interest in helping people like us. I have read all the migration checklist etc and tried a manual code conversion but the complexity of converting our existing code seems impossible : ( or at least very time consuming and prone to errors Just manaualy converting the old style "__property" syntax to the new "property" syntax is overwhelming : ( thousands of them to do etc. This is just one of the problems listed.

    - Dialogs: modalities & etc. Hi again! I have some problem with creating modeless dialog windows. To decribe situation I'm going to show you 2 examples: 1. I have 3 modeless dialog windows (the main and 2 additional). This time I'm opening all of them in WinApp::InitInstance procedure. And in this case all works as I want: if I click on any of all 3 windows - the window gets the focus, moving up over other two other dialogs. That is my aim. 2. All the same - 3 modeless dialogs (absolutely the same) and the same procedures for creating them. But this time I have opened only the main dialog in WinApp::InitInstance. Two additional dialogs are opening by the commands in the main dialog. And in this case I have the problem. After opening any of the additional dialogs the main dialog goes down under the additional. Even if it has the focus! So - this is the question. What is the difference between opening modeless dialogs in WinApp::InitInstance and opening them later (from ON_COMMAND procedures - for ex. from menu commands) What have I to do with main dialog. I want it to go up while getting focus! But not remaining under the additional dialogs! Some comments: all of the dialog windows have these (some of all) constructing modes: 3D look = true border = Resizing style = Popup window edge = true topmost = false system modal = false Visible = true most of others are false Tag: Visual C++ Language Unexpected namespace pollution in VC8 (bug?)

    - Autogenerated copy constructors and equals operators Hi everyone, Anyone know how to inhibit the compiler's autogeneration of copy constructors and equals operators for classes other than defining your own I have a template queue class for which cloning is not really a valid operation, and as such some of it's nested types are not suitable for auto-generated copy constructors/operators. Because of this, when I compile some code that uses the outer template class, I get compiler errors such as: error C2678: binary '=' : no operator found which takes a left-hand operand of type 'volatile T<itemtype>::NestedType' (or there is no acceptable conversion) When I double-click on the error, the editor simply goes to the end of the class declaration that has declared a member of type T< sometype > . Further investigation down the error list yields: This diagnostic occurred in the compiler generated function T<itemtype> &T<itemtype>::operator =(const T<itemtype> &)'. I can fix the error by defining a dummy copy constructor that is a clone of my default constructor, but I feel that misleads programmers using the class into thinking they can clone an instance of that type. Is there anything else I can do Tag: Visual C++ Language Unexpected namespace pollution in VC8 (bug?) Visual C++

    - 64-bit apps need larger stacks than 32-bit In order to make sure this was really the problem, I had created an executable with a larger stack size. In fact, this had solved the problem. I could make do with that solution, but there seems to be a common problem here: regarding the specific dll, all programmers who use it should be aware of this problem (I hope the manufacturer will indeed add a note to the documentation). And generally, any programmer who uses a lot of stack space should be aware of this problem - given that the default will indeed remain as it is now. By the way, my application is actually a COM server, and I do not create any the threads directly. Would you happen to know if the threads created by COM use the default executable stack size Tag: Visual C++ Language Unexpected namespace pollution in VC8 (bug?) Visual C++

    - GetDC() call Hi All, Recently I worked with a code which someone else has written. The code is something as follows BOOL MyDialog::OnInitDialog() { m_pDC = GetDC(); // m_pDC is the member of the dialog class ..... } void RenderBitmaps() { // Many drawing calls m_pDC->SelectObject(bitmap); m_pDC->StretchBlt(....); } In some other functions it is using m_pDC as the device context for draw. Normally at that time, we will call "GetDC()" and from the returning pointer will call the drawing functions. the person who written the code was trying to reduce the code hence make the code faster. So can you see some hidden issue in the above said approach i.e making the DC Pointer as member In the code execution, I dint find any issues :-D What do you feel Tag: Visual C++ Language Unexpected namespace pollution in VC8 (bug?)

At the top I have some excel floating point arrays declared LPFP deposits_zero; LPFP swaps_zero; LPFP futures_zero; LPFP fra_zero; LPFP blend_zero; Now I have a function that is called that sets the deposits, swaps, futures, and fra curve with an array that is dynamically allocated. deposits_zero = USA_CREATE_SWAPZERO(0,0,0,0,curve,&tmpBlend, 1, 1, 3, 0,0,0); It creates a curve, the function is supposed to dynamically allocate my that array. Now later on in my code, I have a function that uses all 4 of those arrays that were set by previous functions. The problem is those arrays aren't there anymore. Whats my problem I am also having trouble getting my Visual Studio to debug my XLL. Thanks, Aaron Tag: Visual C++ Language Unexpected namespace pollution in VC8 (bug?) Visual C++

    - _wstat64i32 undefined Hi: I am converting my code to use Unicode, and have a compile error that I can't figure out. Please help, and thanks very much ahead of time. I've searched the internet for a solution, but even Google doesn't have a search result for even the simplest search string: "_wstat64i32 undefined".

    - Syntax to use pin_ptr on a multi-dimensional array? Hi, I'm trying to wrap a native function with the following parameter: nfunction(long Ustart[][2]) The corresponding wrapper function has the following signature: wfunction(array<long, 2> ustart) { // use pin_ptr to "convert" the manage array to native array // call nfunction() with the "native array" } I know how to use pin_ptr<> for single dimensional arrays but how do I use it in this case Thanks for any help!

Running Visual Studio 2005 Professional, no service pack applied. Here is a code snippet distilled from some code that fails due to unexpected namespace conflicts:

namespace ns1 {
typedef unsigned long ns_t;
struct base
{
~base() {}
};
}

namespace ns2 {
using namespace ns1;
struct dummy : public base
{
};
}

namespace ns3 {
struct dummy2
{
dummy2() {}
ns2::dummy m_dummy;
};
}

ns_t ns_check; //compilation should fail here!!

The above code compiles fine on my machine. The problem is that , for some reason, ns_t is visible at the global namespace when it shouldn't be. Strangely, removing base::~base will cause the behavior I expect (compilation error).

I'm not sure exactly where the bug is and what a workaround might be. If someone from the VC team can reproduce this, I'd appreicate some information on how to avoid triggering the behavior.

I've looked at this and I can report that it was fixed in Visual C++ 2005 SP1.

Great!

It's about time Dinkumware update their compilers by the way. I didn't have VS handy, so I gave it a go with their online ones -- which apparently doesn't have SP1.
