C# has the concept of a static class: a static class is a class that contains only static members and instances can't be created with the new keyword. C++ has no such concept; although you can create classes with only static members you do so explictly and the compiler will not stop you from adding a non-static member.

well explain this error is difficult for me i know this error but i cant say that how you solve this error
|

I also have got yhis problem but
I solve it:
it can be happen if you have a library and you has changed its location.
When you relocate that library, there is no problem

|
|
Even with a Rebuild All?
Have you tried removing the vc60.pdb file?

Yes....but the result is same

Do the following things.
1)Delete all the .obj and .pdb(program database (PDB)) files
2)use the compiler's /Zi option
3)Rebuild the application

have the scroll property checked for both vertical and horizontal scrollbar.
scenario 1:
1) you have Clist box
2) Add few entry to listbox till the vertical scroll bar appears
3) is there any way to find at this point that scrollbar has appeared.
so that i may do some action based on that.
Query :
Any point of time given a LISBOX is it possible to find where VERTICAL SCROLL is visible or available
for thendral

I think u didn't understand what i said
try this..this will add the string to list box untill the scroll bar comes..
for( int nIdx =0; WS_VSCROLL != (m_ListEx.GetStyle()&WS_VSCROLL);nIdx++)
{
m_ListEx.AddString( _T("hi"));
}
// Vericall scroll bar appeared.
// One item will be exceeding the limit..So delete that one..
m_ListEx.DeleteString( m_ListEx.GetCount() - 1 );

Well, this is how I would do it:
CRect clRect;
m_ListEx.GetClientRect(clRect);
int visibleCount = clRect.Height() / m_ListEx.GetItemHeight(0);
while (m_ListEx.GetCount() < visibleCount) {
m_ListEx.AddString (_T("Hi"));
}
Ok, it is a bit of a hack, but given the tools you get in CListBox, this is the best I could come up with.

I see three separate issues here: 1) time; 2) HDD serial number; 3) file I/O. Which are you having troubles with?

Hi
thsi is my code:
<br />
#include <cstdlib><br />
#include <iostream><br />
<br />
using namespace std;<br />
<br />
class C{<br />
private :<br />
int i ;<br />
char * ch;<br />
<br />
public :<br />
C();<br />
C(int,char *);<br />
~C();<br />
};<br />
C::C(int a,char * d)<br />
{<br />
cout << "initializing";<br />
i = a;<br />
ch = new char[strlen(d)+1];<br />
strcpy(ch, d);<br />
<br />
<br />
}<br />
C::C()<br />
{<br />
cout << "default";<br />
}<br />
C::~C()<br />
{<br />
cout << "deleting";<br />
delete[] ch;<br />
}<br />
<br />
int main(int argc, char* argv[])<br />
{<br />
C c;<br />
C * c1 = new C(10,"string");<br />
delete c1;<br />
<br />
return 0;<br />
}<br />
this code when i start debugging ,it compiled then start executing when closing it gives(in VS2005):
"Windows has triggered a breakpoint in sdf.exe.
This may be due to a corruption of the heap, and indicates a bug in sdf.exe or any of the DLLs it has loaded.
The output window may have more diagnostic information"
Why do i get this error in VS 2005 but not in dev c++.What is wrong?I can not the solve the problem in my code or in my debugger or something else..
Thanks...

In your main you declare C c;. This will call the default constructor of C which does nothing. When you leave the main function, the destructor of C will be called and this does:
C::~C()
{
cout << "deleting";
delete[] ch;
}
And ch is not initialized thus you try to free memory that has not been allocated. Always always intialize your member variables in your constructors !!!!
C::C()
{
cout << "default";
i = 0;
ch = NULL;
}
(in your destrutor, you can check the validity of your pointer with if(ch) but this is not required because it is safe to delete a NULL pointer, this will simply do nothing).
