-Set the range of the Slider as 0-255
-Invalidate the rect in Slider position change notification
-create the brush using the slider pos in OnPaint message and fill the Client area Rect of the Dialog.

A_Laxmancreate the brush using the slider pos in OnPaint message and fill the Client area Rect of the Dialog.
I tried that way but the screen flickers a lot and also i don't want to call OnPaint , so i would prefer some other alternative like WM_CTLCOLOR or WM_ERASEBKGND.I want some sample code.

HBRUSH CtestMFCDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)<br />
{<br />
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);<br />
return CreateSolidBrush(RGB(0,0,0));
}
Try the above code you will get the idea what to do next

I want to know how to find out the files which are actually visible in a CFileDialog window at a time.
The files which can be seen at a time without scrolling the List View.
I have attached an image which shows the files that are visible in th
e list view.

Hi,
I have inherited a class from CFileDialog.
I want change the default view menu(menu for selecting the thumbnails view,list view etc.) of the CFileDialog.
I want to add one more option of "Preview" to the view menu.I have overriden the TBN_DROPDOWN event of the view dropdown button but could not find any way to update the view menu which pops up after that.
I have attached a snapshot of the current view menu of the CFiledialog and the place where i want to add the option.
I am NOT extending the CFileDialog using templates.
Any help will be greatly apprerciated.
Thank you.
regards,
Ashwini.

VALUES( ' ") + newurl + _T( " ',' " ) +newlen+ _T( " ',1,1,' " ) +newgpno+ _T( " ',' " ) +newhv+ _T( " ',' " ) +filepath+ _T( " ') " );

Can you brief us a little on what type of error are you getting or are you having problem with what the query enters in the access table?

we are tryin to insert values from user variables into the access db..and this is the format we got to know of..
Now wen we execute this line..it throws an exception.
Is something wrong with d syntax(a missin comma,an xtra bracket or something)??

|
|
Try Format(...) instead of this

How can i convert a class _variant_t variable to integer/long int?
Tried typecasting,ChangeType..dint help..
i want to be able to use '+'(mathematical)..

This appears to work but this is the first time I've tried this so be careful since I'm shooting from the hip...
_variant_t vtInput("1234");
int nInput=_wtoi(vtInput.bstrVal);
TRACE("Input + 3 = %d\n",nInput+3);
-- modified at 0:21 Saturday 17th June, 2006
This also appears to work
_variant_t vtInput("1234");
vtInput.ChangeType(VT_I4);
TRACE("Input + 3 = %d\n",vtInput.intVal+3);

What i think is this should do:
BSTR bstrText = ::SysAllocString(L"Number Text Here");
char* lpszText2 = _com_util::ConvertBSTRToString(bstrText);
int i=atoi(lpszText2);
SysFreeString(bstrText);
delete[] lpszText2;

As _bstr_t is wrapper class for BSTR, it also Expose LPCTSTR operator:-
so you can easily call itoa directly on _bstr_t object!
