Is this a "feature" of VC 6.0 only?
The associated list box puts the scroll bar on the right and aligns the text on right also.
Now the user have to select the list box from left and select from the list box on right.
It is not a major problem, but...

Why have you not bothered to check the CFileException object? That might give you a big clue as to what is happening.

I have a VC6 project, class-view info file is damaged, VC6 shows:
"Cannot access the ClassView information file, ClassView information will not be available."
when opening its project file.
How to recover the damaged file?
|
|
|
|
|
close ALL your instances of VC6, check in the task manager that there are no ghost instance.
delete all ncb, aps(?), clw, ... files (all support files) from your different solutions; reload you projects and rebuild them all.
Watched code never compiles.
|
|
|
|
|
Yes, I got answer from Google, which says rebooting computer.
It is fine now.

You can't. Just delete the file and let it get rebuilt.

hi,
Everybody,
i am trying to use parallel port to send data to it using vc++, i have added LED's to know if it works fine.
I have included inpout32.dll in my system32 directory and inpout32.lib is linked to my project, i have even placed inpout32.dll at my projects directory.
When the project executes, it gives no error, but output doesnot appear at LEDs.
please let me know if there are any errors in my code below, or anything that can help me to see output  
#include <conio.h>
#include <stdio.h>
void _stdcall Out32(short PortAddress, short data);
int main () {
Out32(0x378, 255);
printf("DTA SENT");
return 0;
}
|
|
|
|
|
Never having used Out32()... Have you verified that 0x378 is the correct address of the parallel port on your machine (and it is enabled)? Have you ruled out hardware problems, LED's that are backwards, ground(s) not connected...
|
|
|
|
|
Yes jeron
I have made sure all about that, port is enabled, adress is 0x378,
that is only why i am getting nuts. i just cant figure out what is wrong and where is it wrong

Thanx It worked

Hi all,
I would like to use STL <numeric> adjacent_difference function in my program but I'm getting the error:
1>c:\program files\microsoft visual studio 8\vc\include\numeric(349) : error C2440: '=' : cannot convert from 'Csimple' to 'int'
1> No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called.
I have a <list> of Csimple's (udt) objects where I would calculate the differences (Csimple is a very simple class with only one int parameter called "firstInt").
list<Csimple> simpleList;
simpleList.push_back(Csimple(10));
...
simpleList.push_back(Csimple(25));
vector<int> res(simpleList.size());
vector<int>::iterator v_resItr;
v_resItr = adjacent_difference(simpleList.begin(), simpleList.end(), res.begin());
I've also added the overloaded version of operator- and operator= as class members as suggest by errors provided by compiler
Csimple Csimple::operator -(Csimple op2)
{ return firstInt - op2.firstInt; }
Csimple Csimple::operator =(Csimple op2)
{ return firstInt = op2.firstInt; }
I assume that I can use adjacent_difference also with user-defined type rather than just int; may be my assumption wrong?
Can someone help me, pls?
Many thanks in advance

Try to add an operator to your class :
...
public:
operator int() { return firstInt; };
...
(please see the file of the error:
for (*_Dest = _Val; ++_First != _Last; ))
virtual void BeHappy() = 0;

We have a window that displays a 2D grid, consisting of points connected by lines to form a rectangular network. The outline is irregular, and the point spacing may vary slightly. This represents an array of shots taken during a geophysical survey. The problem is that for a typical grid from a marine survey the rendering is rather slow, and when the user zooms in or out they must wait several seconds for the screen to update which is not good. Also if the user moves the window, the redraw takes several seconds, which looks a bit crap. Does anyone know if using DirectX would produce faster rendering? If so, what sort of performance gain would we see? Incidentally I assume DirectX 9 as we need to maintain compatibility with Windows XP, if not Win2K.
