You are using same window handle as hWndInsertAfter . Refer documentation for correct parameter.
And you are giving 0 and 0 as width and height of window. (Again, refer documentation)

Having a zero width and height is fine - that is what the SWP_NOSIZE flag allows for (they are ignored), and since he also specified the SWP_NOZORDER flag, the first HWND parameter is ignored as well (I would say to "refer to the documentation", but that would be just plain scarstatic my telling that to an MVP...). His problem is with one of the other flags he sets, can you guess which one...?

Peace!

Yup, by seeing first two flags, I overlooked last parameter. My bad.

CDateTimeCtrl::GetTime() what it return? UTC or something else?

int i= ((CWnd*)this)->SetWindowPos((CWnd*)this ,1038,73,0,0, SWP_NOMOVE | SWP_NOSIZE | SWP_NOZORDER | SWP_FRAMECHANGED);

You are specifying the SWP_NOMOVE flag, which tells the function not to move the window, which is exactly what you are trying to do! You might want to ~~add the SWP_NOZORDER flag and change the first parameter to NULL as well~~ (sorry - did not see you already had that flag set).

Peace!

It's a user input control. It returns whatever the user set the value to.

goodmorning i am trying to type a fuction that it return me how many times a str exist in a line .Christian told me to work with CString Find but i have some problems here :/

Problem is, i think ,my while loop is wrong and my program becomes (Not Responding)

int CInfoRecoverDlg::Compare( CString line , CString str2)
{
int nCount = 0;
for (int i = 0 ; i < line.GetLength() ; i++)
{
while ( line.Find(str2,i+1)!= -1 )
{
nCount = nCount +1;
}
}
return nCount ;
}

void CInfoRecoverDlg::OnButton1()
{
CString str = "yes";
CString line = "yes i said yes , yes ";
int nCount;

nCount = Compare( line , str);
AfxMessageBox(""+nCount);
}

Have you tried to debug the code ?

Immunity18 wrote:

I guess, you could modify this to,

while ( line.Find(str2,i)!= -1 )

Again, I'm not sure about aim of the function.

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

ON_NOTIFY_RANGE problem!

17-May-07 22:52

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.

TPN wrote:

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!

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.
