Try to this code
int CMyDialog::Compare( CString line , CString str2)
{
int nCount = 0;
int index=0;
for (int i = 0 ; i < line.GetLength() ; i++)
{
index=line.Find(str2,index);
if( index!= -1 )
{
nCount++;
index++;
}
else
return nCount;
}
return nCount ;
}

Hi all,
I design a form with about 50 combo boxes and I want to handle the notification message CBN_SELCHANGE of those combo boxes in a same routine, so I use the macro ON_NOTIFY_RANGE(CBN_SELCHANGE, IDC_COMBO1, IDC_COMBO50, MyMsgHandler).
But it seems that nothing happens. Am I wrong?
Pls help me to solve this.
Thanks in advance.

ON_CONTROL_RANGE try this. I hope it will solve the problem

What happens if you use ON_NOTIFY for only one of the controls?

Thanks you for your help!
I don't want to use ON_NOTIFY because there are many controls and this will cause many ON_NOTIFY macro.
I try with ON_CONTROL_RANGE and it work fine. But I am still not clear the difference between ON_NOTIFY_RANGE and ON_CONTROL_RANGE...
Once again, thank you.

I know, my point was that if something doesn't work you should revert to the easiest way to test that you've got the concept down correctly.
You thought there was something wrong with your use of the ON_NOTIFY_RANGE mechanism, but if you would have tried with the simpler ON_NOTIFY you would have found that it won't get called since the control sends a WM_COMMAND notification and not a WM_NOTIFY notification.

The difference is that it handles two separate windows messages: WM_COMMAND and WM_NOTIFY.
For actions that send WM_COMMAND notifications you have to use ON_CONROL_RANGE.
WM_NOTIFY was introduced with Win32 API to send notification messages that requires more information and the message handler receives a pointer to a NMHDR struct with control specific data. WM_NOTIFY didn't exist in Win3.x API.

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.
Peace!

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

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.

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.
