This thread is a user-interface thread, I overrode CWinThread and pass the runtime class name to AfxBeginThread just as the documentation say you're supposed to do for a user-interface thread. I was trying to figure out a way to use messages but maybe I don't know as much as I need to.
I defined a message like:
#define WM_UPDATECHILD (WM_APP + 1)
And tried to create a handler function for that message but it would never be run. I tried to override PreTranslateMessage, OnCmdMsg, and OnCommand to intercept this message, handle it, then return a nonzero result to show it was handled and none of this worked. I just don't know what to do.

When you invalidate a rectangle/region, this area does not get updated straight away. It will get updated the next time Windows decides to send your app a WM_PAINT message.
To force an update after you invalidate a region, call the UpdateWindow API

can an MFC DLL server created in VC be used by a VB client? because most articles that i read that allows VB client are ATL and win32 dlls.
|
|
|
|
|
if you are talking about ATL com, yes.
Then you need to take care of data been exchanged between VB and COM.
I dont remember where, but somewhere I have read on how to write a COM object in VC for VB.

I'm having to develop an application that keeps track of horses with their winnings and other such information dealing with horse races. We only have to track 3 horses, but what if there were 100 horses, which it'll have to do eventually? I don't want to have to type HorseName.ShowStatistics that many times. Is there a way to loop through the horse objects and run that specific objects method within the loop? How would I go about doing that?
Thanks

Horses oHorses[100];
or Horses *pHoress = new Horses[100]
<<Initialise the horses members>>
for(i=0;i<100;i++)
{
pHorses[i]->ShowStat();
}

To complete previous response, you can use the vector from the STL. This will allow you to have an array of objects (Horses in your case) where you can dynamically add and remove elements.

I compile the following C++ code VS.NET2003 IDE and the compiler enter an infinit/endless compiling process, What's wrong within it?
The code is given as following:
//The testtempl.h
#ifndef __TESTTEMPL_H__
#define __TESTTEMPL_H__
#include <stdlib.h>
#include <stdio.h>
#include <vector>
template<int n> class MyTempl
{
public:
std::vector<int> m_array;
public:
MyTempl()
{
m_array.assign(n, n);
}
int Summation()
{
int rn = 0;
for(int i = 0; i < (int)m_array.size(); i++)
rn += m_array[i];
return rn;
}
int Foo()
{
if(n <= 1)
return 1;
else
{
int r = 0;
MyTempl<n-1> mtempl;
r = mtempl.Foo()*Summation();
return r;
}
}
};
typedef MyTempl<4> My4Foo;
#endif
//The testtempl.cpp file
#include "testtempl.h"
int main(int argc, char* argv[])
{
My4Foo myfoo;
int i = myfoo.Foo();
printf("foo value: %u\n", i);
return 0;
}

First of all, check 'do not treat < as html' below, so we can SEE the code
I think this line
MyTempl<n-1> mtempl;
means that every time the compiler creates a template class, it needs to create a new one, recursively forever. Hence the error.

I haven't tested it, but I think one way to avoid the problem while maintaining the recursive nature of the solution would be to do as follows:
In the class declaration, declare only the prototype for the Foo method:
int Foo();
Then, provide a general implementation for Foo():
template<int n>
int MyTempl::Foo()
{
int r = 0;
MyTempl<n-1> mtempl;
r = mtempl.Foo()*Summation();
return r;
}
Finally, provide an explicit implementation for the 1 case, so as to end the recursion:
template<1>
int MyTempl::Foo()
{
return 1;
}

Kinda offtopic question;
Whenever I startup Windows Media Center, the actual program, not the OS, Visual C++ starts up and starts debugging. Everytime (I think its called ehShell.exe), the debugger starts up. Its slowing down the computer significantly. Is there anyway to stop this from doing it? Thanks alot

There are books on some Boost libraries, like Graph, and metaprogramming, but AFAIK, no book covers "all Boost".

There are some examples of video capture here[^] as to the detection is this motion or shape? This is more specialist so maybe searching MDSN will help. If not, a careful Google search is next.
