To further clarify Roger's point - the "older" Windows controls, meaning the ones available in 16-bit Windows like Button, Edit, Static, ComboBox, ListBox, etc. all use WM_COMMAND for their notification messages.
The "new" 32-bit common controls, such as the ListView, TreeView, Progress Bar, Slider, Rich Edit, etc. all use WM_NOTIFY for their notification messages.
If using MFC, the easiest way to tell the difference is that the older control's wrapper classes do not end with Ctrl and the newer ones do. For example, the MFC class for the (older) Button is CButton and the class for an (older) Edit is CEdit, while the class for a (newer) Rich Edit is CRichEditCtrl and the class for the (newer) TreeView is CTreeCtrl. So if your control's wrapper class ends with Ctrl, use the WM_NOTIFY-based handlers.

Good point James.

See this[^] article its about Pdf but it has Nero SDK

Thx, I checked it out, but I can't find SDK for downloading it!
I need IMAPIv1 because I'm running on XP! I'm also wondering is it possible to copy data on DVD? According to msdn it is not possible to do so, only using IMAPIv2 which requires Vista???
If anybody knows solution for this (not using Nero SDK or similarly) please let me know how.
Thanks to all

I think it's in the platform SDK.
But you are correct, version 1 can't burn DVD.
I don't know of any other alternatives.

Do you mean the February 2003 version (which is a latest windows SDK that supports Visual Studio 6.0?)or you mean new Windows SDK (Date Published: 8/24/2006, combining of the Platform SDK, .NET Framework SDK, and WinFX SDKs)?
Or could you post link, please.
THX!!!

Hi all
I am currently using VC++ 6.0 and Crystal Reports 8.5. I have placed a Crystal Report Viewer in my dialog box, i dont understand how to populate it with a report at run time. I tried finding the features this tool offers but was not able to find any solution to my problem.
I kindly request anyone of you to provide me the information to make it happen.
Thank you very much
Kind Regards
Sandy

How are you copying the file to the destination?

Did you try and check by debugging what is happening behind your code? If not, please try it out.
Somethings seem HARD to do, until we know how to do them.

yes i debug it properly and i dont find any exception in opening and writing a file. and it will properly working on Common folder in vista like C:\
but not in C:\windows\fonts.
i import ttf file using resource and just copy and paste that file to fonts folder.

Hi,
I have the following function
int DataPeakCompareFunc(const void *el1, const void *el2)
{
const DataPeak *peak1 = reinterpret_cast<const datapeak="" *="">(el1);
const DataPeak *peak2 = reinterpret_cast<const datapeak="" *="">(el2);
if (peak1->position < peak2->position)
{
return -1;
}
else if (peak2->position < peak1->position)
{
return 1;
}
return 0;
}
I am calling qsort function with the below parameters
qsort((void *)pScan, num_readings, sizeof(DataPeak), DataPeakCompareFunc);
Then i am getting the above error.
What to do?
Thanks in advance

qsort((void *)pScan, num_readings, sizeof(DataPeak), <code>&</code>DataPeakCompareFunc);
Remember that this function should not be member function. Either it should be static or a global function.
Lookup qsort. Here is the callback function signature.
int (__cdecl *compare )(const void *elem1, const void *elem2 ) BTW why are you posting the whole error as caption for your post. Looks odd.

I swear I already answered this. I'll repeat:
Don't use qsort: it's crap, old, not type safe, etc....
Use STL instead. Here's an example:
#include "stdafx.h"
#include <algorithm>
class CData
{
public:
CData(int val) : m_val(val) {}
friend bool operator<(const CData &l, const CData &r)
{
return l.m_val < r.m_val;
}
private:
int m_val;
};
int main(int arvc, char* argv[])
{
CData SortMe[] = {10, 9, 8, 7, 6, 5, 4, 3, 2, 1};
CData *pOnePastEnd = SortMe + sizeof(SortMe)/sizeof(SortMe[0]);
std::sort(SortMe, pOnePastEnd);
return 0;
}

What do you mean by type safe? We are ones who's using it and we know what types we are passing to it. So how can you say it's not type safe.

STL is obviously simpler, easier to understand and less messier than qsort can ever be. STL code would execute faster than the routines that we may generally write. Did you notice the STL code to sort a given array? That is 1 line! Brilliant use of operator overloading. If you are writing c++ code, I don't find a good reason to use qsort, instead of STL.

That doesn't mean qsort is crap and not type safe. If you are using it, then you have reasons. It's just a function call, I've used it, works well.
My company does not use STL. So qsort works well.

Why do you tell that to *me* 
Nibu babu thomas wrote: It's just a function call, I've used it, works well.
It works; I never said no. I was trying to compare qsort with an STL based solution. I felt when compared, STL is much better. My point is that if STL could be used instead of qsort, it must be, IMO!!
PS: I'm not voting you one.
