Why not just use CString from MFC? I think it contains the proper overloads to address that situation. However, I would listen to the poster "Waldermot". I think what he recommends would enable you to understand some important principles that you can successfully apply later.

I've got nothing against CString but all things being equal you're better off using std::string. For one it means you've got less porting to do if you decide to move the application to another platform.

I would like to include a validation that excludes carriage returns, on the lines of,
...
{ fileToRead.getline(strLine, MAX_SENTENCE_LENGTH);
if (strLine != CRLF)
{Sentences.push_back(strLine);
Size++;}
}
...
How do I validate strLine, perhaps through the ASCII code?

getline strips out the CR/LF - this may be giving you problems.

No actually the problem is that when there is an empty line (assuming a CR/LF) ONLY I would like to skip a block of code.

THERE WILL BE NO CR/LF - it will be an empty string. You are misinterpreting the problem. getline takes out the CR/LF but advances the file pointer, your code clearly indicates that you are looking for an empty line that includes the CR/LF. That is your problem.

Hi everybody, can anyone tell me how to display a dialog in a SDI application (the dialog has the CRecordView class as a base class). I just need to display a few records from an Access database in editboxes in my dialog. (That's for VC++ 6.0)
And my second question will be: I have a dialog in VC++ 2005 , but i can't assign appropriate class like CRecordView (I can only CFormView, CDialog, COLEproperty etc.)
Thanx everybody in advance

Thanx, but could you be more precise, this is a site for training, i need some tutorials and stuff, if you can point me to that kind of page that would help me more.

You can't do this. Dialogs are derived from CDialog, whereas views are derived from CView. CDialog and CView are on different branches of CWnd.

I have VS2005
Experimenting with header file is quite difficult because most of the time I do so VS2005 eat up 100% CPU and, slowly, all the memory as well (1GB, 2GB, 3GB, ... piou...... (reboot button))
Now I have been told that header file should speed up my compilation (which is rather slow even though the Managed C++ project is small)
Because I include <windows.h> in many headers (needed to define some enum from Windows constants) I though: OK: let's #include <windows.h> in stdafx.h.
But I have a doubt.. does it makes any sense to include a precompiled header in other headers?

|

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 ??
Sid.

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
