    - Win32 Thread Interleaving It seems to me that your code is a victim of a change made in Win2k3 SP1 to avoid lock convoys (see http://www.bluebytesoftware.com/blog/CommentView,guid,e40c2675-43a3-410f-8f85-616ef7b031aa.aspx for one of many discussions about this). Since this is not related in anyway to the C++ language I suggest you to use the MSDN Newsgroups since you have a better change to get a complete answer: http://msdn.microsoft.com/newsgroups/default.aspx dg=microsoft.public.win32.programmer.kernel&lang=en&cr=US Tag: Visual C++ General Open a new form from another form Visual C++

    - Why SetLastError doesn't work? SetLastError will only work in this instance if you check the reply value with GetLastError Before any other function that uses SetLastError is called, Thus to do what you are doing the call as follows: Function: int Func() { SetLastError(x); return 0; } code... if (Func()==0) { errorcode=GetLastError(); do other stuff; } else do other stuff; Tag: Visual C++ General Open a new form from another form Visual C++

    - Error compiling 64 bit VS 2005 __in is not recognized From MSDN: If you examine the library header files, you will notice some unusual annotations such as __in_z and __out_ecount_part . These are examples of Microsoft's standard source code annotation language (SAL), which provides a set of annotations to describe how a function uses its parameters—the assumptions it makes about them, and the guarantees it makes upon finishing. The header file <sal.h> defines the annotations. Have you tried including <sal.h> before those header fiels you mention This should make the problem go away.

    - Heap corruption ... bookysmell2004 wrote: What am I doing wrong Not to be excessively facetious but one thing you are doing wrong is implementing your own string class. There are several good string classes available for use and you would be much better off using one of them. The CString class for example: http://msdn2.microsoft.com/en-us/library/ms174288(VS.80).aspx Code Snippet void LString::Replace(LString s, LString p) { while (IndexOf(s)>0) { char *Temp = new char[Length()+s.Length()-p.Length()]; int i = 0 ; for (i=0 ; i *(Temp+i) = *(Chars+i); } for (i=0 ; i *(Temp+IndexOf(s)+i) = p[i]; } for (i=IndexOf(s)+s.Length() ; i *(Temp+p.Length()-s.Length()+i) = *(Chars+i); } *(Temp+i) = 0; Copy(Temp); delete [] Temp; } } One problem with the code above is the calculation of the size of the array Temp. The Replace method will modify the current string by substituting the new substring p for the old substring s. Thus the length of the modified string will be the length of the original string reduced by the length of s and increased by the length of p. The calculation above gets that reversed - it increases by the length of s and reduces by the length of p. If p is longer than s, the calculation will result in a Temp that is too short and replace will overflow off the end of Temp and into the rest of the heap. The calculation of the length of Temp also forgets to allow for the null character. The function Length () returns the number of characters in the string not including the null termination. In your particular case, the original string is length 3 and the strings s and p are both length 1. Thus, Temp is size 3. But, Temp has to be long enough to hold the modified string (also length 3) plus the null inserted by the statement *(Temp+i) = 0; Code Snippet LString::LString(const LString &s) { Copy(s.Chars); } Another problem you have is that this constructor never calls new to instantiate Chars. Thus, when Copy () calls delete to delete the object this.Chars the member Chars isn't pointing at anything (at least nothing created by new).

    - Porting To Visual Studio 2005 Hello, I'm trying to port a program that was written in Visual C++ 6.0 to Visual Studio 2005. After not having much success I tried to port it to VS2003 and was able to get the program to work. I then took that port and tried to get it to work in VS2005 and was able to get most of it to function but one part. I have a edit box and a slider box, either one can be used, to enter a floating value between 0 and 1. When you try to select either a message pops up saying "Please enter a value between 0 and 1000" and you are not able to change any values before this message pops up, and then a debug assertion error is given. I have checked over all the math and it remains the same as the VC++6.0 and VS2003 that both work, and the only part of the code that was changed was when some pow() functions where used to solve and problem with ambiguity (I cast the values as being double since I am under the impression that VC++6.0 pow() fucntion could only take doubles) Any ideas of where to start would be great.

    - 'std' : does not exist or is not a namespace Hi Geo, If you're using precompiled headers the compiler will ignore anything above: Code Snippet #include "stdafx.h" You need to move your include to <iostream> below this line or put it inside stdafx.h.

    - Member template function which takes member function pointer as non template parameter. I'd expect both point 1 and 2 to compile, but clearly they don't. There have been a few other reportings of similar issues, so these may already have been submitted as bugs. You should go to http://connect.microsoft.com/VisualStudio and do a couple of searches, but probably report your findings as two separate matters given the same steps to reproduce as shown above.

    - Designer Custom Event with a Delegate Disappears from property window Ok, so maybe posting some code will help And steps to reproduce this what I feel will turn out to be a bug. 1. Create a c++ windows forms project (call it testform if you will) 2. Create a c++ user control project (call it car if you will) 3. Create a c++ class that derives from System::EventArgs and assign it some quick properties or so. Code Block #pragma once using namespace System; using namespace System::ComponentModel; using namespace System::Windows::Forms; namespace Car { public ref class FuelEmptyEventArgs : System::EventArgs { public : //constructor FuelEmptyEventArgs( void ) { locationX = 0; locationY = 0; }; FuelEmptyEventArgs( int X, int Y) { locationX = X; locationY = Y; }; property int LocationX { int get( void ) { return locationX; }; } property int LocationY { int get( void ) { return locationY; }; } private : int locationX; int locationY; }; } //namespace 4. Inside your control create a delegate, and an event. Code Block public : delegate void FuelEmptyHandler(System::Object ^sender, FuelEmptyEventArgs ^e); event FuelEmptyHandler ^FuelEmpty { void add(FuelEmptyHandler ^value) { PrivateFuelEmpty += value; } void remove(FuelEmptyHandler ^value) { PrivateFuelEmpty -= value; } } private : FuelEmptyHandler ^PrivateFuelEmpty; 5. Build and add the control to the tool box or if your ide is setup like mine it will add it for you. 6. Open your testform and drop your user control onto the form. 7. Select your user controls properties and then the event tab 8. Double click on your custom event (In my example it is FuelEmpty) and should be under misc. 9. Add a message box or something to the event it creates. 10. Close the form 11. Open the form back up and check if your event is still present... (notice it is not) 12. Move your control or change something to cause the designer to resave the code. Now your event is completely unassigned I hope this encourges some sort of better response Tag: Visual C++ General Open a new form from another form Visual C++

    - Convert string to LPCTSTR If you need a LPC T STR, you should create a generic "tstring" type, which resolves to wstring for UNICODE builds and string for multibyte. If you what you need is really just a LPCSTR (in other words; you're compiling for multibyte only), use the string's .c_str() member function.

    - This code snippet makes no sense... Bapa wrote: D3DXMATRIX *D3DXMatrixIdentity(D3DXMATRIX *pout); That type of function is very common. Bapa wrote: "D3DXMATRIX" is a type, of course. And "D3DXMatrixIdentity" is a function, of course. Now I don't see how this works. Not of course. The type is not "D3DXMATRIX"; it is "D3DXMATRIX * ". You might need to use a tutorial or book about the C++ language to understand what a "D3DXMATRIX *" is but it is a pointer. The function returns a pointer. Bapa wrote: Okay, to break it down, first we have a type, which is D3DXMATRIX, then we have the indirection-operator (which I assume is a pointer), and then we have a function (perhaps a call) with a new D3DXMATRIX (pointer) as it's only parameter. How the heck does this work It isn't just a regular function-call. It isn't a function-call that'll return anything to something, so whaaaa It is very common and the only reason it seems unusual is that you are unfamiliar with C++.

Hi all,

I'm using VS2005, VC++

I want to open a new form form another form, and I also want to close the old form after new form open.

Just like Form1>>open Form2>>close Form1

I try many ways, but it didn't work.

THX!
