I think you mean 'precompiled header', but from what you say this is not your problem. The precompiled header is just a standard header file 'stdafx.h' that is included in all your files. In it you should include all the header files you use most often, ie windows.h, vector, string...
But again, this doesn't sound like your problem of the CPU speed and memory

Do you mean you want to change the images, or that you want to add and remove buttons ?

As part of a sort algorithm I am copying the contents of a vector to a local dynamic array (temporarily) prior to sorting them (using a simple algorithm such as bubble sort).
CSentenceList.h
--------------------------------------------
class CSentenceList
{
public:
...
//Properties
unsigned int Size;
vector<string> Sentences; //list of sentences
...
private:
...
//Properties
string* m_tempList; //used for sort
};
CSentenceList.cpp
--------------------------------------------
....
void CSentenceList::sort()
{ m_tempList = new string[Size];
//copy Sentences to m_tempList
for (int iIndex = 0; iIndex = Size; iIndex++)
{m_tempList[iIndex] = Sentences[iIndex];} // ERROR!
Sentences.clear();
// sort the array
...
delete [] m_tempList;
}
However the code breaks during the assignment of the contents of the vector to the dynamic array (memcpy.asm), when trying to read from memory.
Error: Access violation reading location 0xabababab.
I am declaring m_tempList as a string* otherwise I wouldn't be able to create the array using the 'new[]' operator.
Any ideas? Any simpler way to sort?

You're sure that Size is the size of hte vector ? Either way, it's redundant, you should be pulling the size from the vector itself.
In any case, you should be using one of the sorting algorithms that come with the stl. Something like
#include <algorithm>
std::sort(Sentences.begin(), Sentences.end());
That's totally from very old and disused memory, but it's along those lines.

Your for loop has problems:
{ m_tempList = new string[Size];<br />
<br />
for (int iIndex = 0; iIndex = Size; iIndex++)<br />
{m_tempList[iIndex] = Sentences[iIndex];}
Since you allocated Size items, the index has a maximum of (Size-1). In the test of your for loop (iIndex = Size), you are setting the value of iIndex to Size instead of testing it for the limit. Your code in the for loop then tries to set the [Size] member to the value - illegal since it onlly has [Size-1] members.
Perhaps you mean:
<br />
for (int iIndex = 0; iIndex < Size; iIndex++)<br />

A server application i made on PC having Windows XP and Visual Studios 6 is running fine on another windows XP machine (after supplying 4 DLL files). But it is not running on a Windows 2000 professional platform. Any solutions ??

Possibly XP had a library already that you depend on, and 2000 did not ? It would help to find out what the exact problem is.
Also, perhaps you used an API that was new to XP in your code ?

Download the Dependency Walker application and run it on your DLL files. If you find a DLL with a function that has an exclamation point by it that means that that dependency is not resolved hence the dll cannot be loaded. This could be why your application is failing.

Use from Dependency Walker.Maybe you use from a service that is in xp and isnt in 2000

If bring the *.exe which build by VC++ to run in another PC that don't have VC++ is installed, it will show error and can't use this program.
Anybody know, how to solve this problem.

probably you are missing libraries ...

If you're running on XP and using VS2005, you need to run the redistributable file which will install them to the correct WinSXS folders. The .manifest file also needs to ship with your app in this case. If you're < VS2005, then files like the MSVCRT and the MFC dll need to be put in the system32 folder of the target machine, if you used MFC and the C runtime ( cancel one or the other as appropriate ), unless you link them into your app, which makes your exe bigger.

The application program will ask for DLL files when you run it in another PC which does not have Visual Studio installed. Copy the required DLL files from a PC having Visual Studio into the folder which has the application and run it.

WinSXS means this does not work anymore for XP, at least not for VS2005 built programs, AFAIK.

Select static linking for the MFC libraries then they are built into the binary.

Where is this option?
Is it in VC++?
|
|
|
|
|
You've probably found it by now, but it's in your project properties.

Right click in solution->select property->in Use of MFC select Static

You should add many ".dll" to the other PC!
If you do that,the problem will be solved!

I will start to learn win32 and com.Com is a part of win32.right?
I am vague of starting win32 books and com books first?
In fact i don't sure what are the steps for learning win32.I see that most of the tutorials showing win32: learning message dispatch system of windows or to learning what functions included in system32 dlls.
Which roadmap must i follow to learning win32 and com.
I decided that first learning com(I have 3 books) and then win32(ı have 2 books).
Is this right way?
What do you advice me?
