Hi
Anyone used the ASTL library before in Visual C++? I am trying to use the ASTL library but am getting compile errors:
Compiling...
astl.cpp
c:\astl\astl.beta.2.0\include\dfa_matrix.h(108) : error C2955: 'char_traits' : use of class template requires template argument list

Please help.
Thanks a lot.

Hi
I am beginner learning C++ and using the Visual C++ compiler. How do I add class templates so that I can use it in Visual C++? Please highlight the steps.

Hello,
The steps for success are the following:
1) Do a Google search
2) Apply the results
3) If errors are the result, search some more. (More Google, MSDN, CP,...)
4) When your head feels like exploding, ask here on CP
Until you tried steps 1 through 3, you should try doing your homework yourself...
Multiply it by infinity and take it beyond eternity and you'll still have no idea about what I'm talking about.

I get compile errors when using iostream.h and fstream.h includes
while using .Net Pro 2003, but not VC++6.0 nor .Net Architect 2003.
How do I resolve this?

try just typing #include < iostream > //without the *.h Thats working for me

header files with *.h are not ansi standard, therefore they are not 100% supported in .net

Hi!
I created this class inside a dll file.
But how do I access it through my application?
It wasnt as easy as I thought it would be.
I tryed typing:
class __declspec(dllimport) CNetwork;
But that doesnt seam to work, just to create a whole new class called CNetwork. I couldnt access any of the functions I had in the class in the dll-file.
What to do?
Thanks

use MFC Extention DLL and using AFX_EXT_CLASS macro export your class.
butbefore importing it in you application first include the header file which contain Class Declartion and the Lib file which contain runtime symbol for linking.

on your IDE's menu, click Project->Add Existing Item, and add the header file that way

press ctrl+F5 if your using Visual Studio.
or add #include < Windows.h > among your header-files
and system("pause"); on the buttom of main function

You can also use getch() which is defined in conio.h.

Hi there,
I am developing a piece of code to grab images from Video files. Is the Video For Windows API still the way to go? As a side note, does anyone know how easy it is to grab images from DVDs?

I am trying to store top score (CString and int) (name and score) values to the registry
They are declared in the CMainFrame Class and initialized with the default values and in OnCreate from the stored values from the registry i debugged it and seen that they are okay till the end of the OnCreate function;
Used WriteProfileInt & WriteProfileString In OnClose and
Used GetProfileInt &GetProfileString In OnCreate
I wanted to update the values when the game is over and when game is over i post a message using PostMessage in The CView and in the handler function i use
((CMainFrame*)AfxGetApp())->m_strTopScore => now this value is null
((CMainFrame*)AfxGetApp())->m_iTopScore => now this value is 512
But As I said earlier the m_strTopScore was assigned a default value of "New Player"
and the m_iTopScore=0;
and when i try assign the m_strTopScore with new value
((CMainFrame*)AfxGetApp())->m_strTopScore="New String";
i get an ASSERT in line that says
_AFX_INLINE CStringData* CString::GetData() const
{ ASSERT(m_pchData != NULL); return ((CStringData*)m_pchData)-1; }
I used regedit and seen the stored default values in OnCreate i.e "NewPlayer" and 0
Why is the Value of 0 changed to 512 and NewPlayer to null
There is no place this variables are modified ??????? Any Ideas???????

Your question is a little confused.
Are you storing your data in your CFrameWnd derived class (CMainFrame) or in your CWinApp derived class.
AfxGetApp() returns a point to a CWinApp class and not your CMainFrame
You need to use AfxGetMainWnd to get a pointer to your CFrameWnd derived class.

you should also be able to use CView::GetParentFrame()

Sorry, I didn't mean GetParentFrame(), I meant GetParent(). This is a line of code that I use in one of my applications:
CMainFrame* pFrame = (CMainFrame*)GetParent();
then use
pFrame->m_strTopScore ;
make sure your variables are in the public section of your class definition for CMainFrame and make sure you #include "Mainfrm.h" in your view's .cpp file.

ShellExecute(NULL, "open", "myapplication.exe", NULL, NULL, SW_SHOWNORMAL);
that will open an application and start it called "myapplication.exe", of course you'd have to replace that with the real name of your app. However if an application is already open, you would probably have to use something like FindWindow() to get the window's hWnd, then call SetForegroundWindow() or something like that.

Hello,
I have a program program that is leaking memory. I commented out all the code that possibly could cause the leak, but the leak is still there. The following code is all there is left:
<br />
int main()<br />
{<br />
return 0;<br />
}<br />
And when I run this code I get the following leaks:
Detected memory leaks!
Dumping objects ->
{46} normal block at 0x00A42760, 792 bytes long.

The thread 0x58C has exited with code 0 (0x0).
I'm using STLPort with _REENTRANT defined and VC6.0. Are there any memory leaks in STLPort that I should know about?
Multiply it by infinity and take it beyond eternity and you'll still have no idea about what I'm talking about.

I think that is not memory leak
