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.

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..

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;
Somethings seem HARD to do, until we know how to do them.

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

codes:
CDlgBrower *dlg=new CDlgBrower;
dlg->Create(IDD_DLG_FILE);
dlg->ShowWindow(SW_SHOW);
how to judge that the dlg is destoryed?
if it didn't destroyed , show it!
else new a dialog and show it !
what to do?
Just my interest for these common things

Try this:
if(dlg)
{
dlg->ShowWindow (SW_SHOW);
}
else
{
dlg=new CDlgBrower();
dlg->Create(IDD_DLG_FILE,this);
dlg->ShowWindow (SW_SHOW);
}

u can use the IsWindow function to check whether a handle is a valid window handle.
if( IsWindow( dlg->m_hWnd ))
{
// Window exists
}
else
{
// Invalid handle
}

When ever your Dialog is destoyed or closed are you calling Delete on Object?

Do we have any good effective WIN32 API which can tell whether my application is running on a system with a color v/s monochrome monitor attached.
A sample code snippet will be helpful.
Am using the following sample and apparently its not giving correct results always.
bool bColorMonitor = false;
// Get the display information
DEVMODE devmode;
if (::EnumDisplaySettings(NULL, ENUM_CURRENT_SETTINGS, &devmode))
{
//If dmDisplayFlags is set to zero then monitor is colored otherwise GrayScaled.
bColorMonitor = !(0x01 & devmode.dmDisplayFlags);
}
else
{
dirTrace.Error(_T("EnumDisplaySettings() failed"));
}

Hello,
I need to draw 1 line and 1 bar chart on 1 plot.
I can't find a way how to do that.
I tried the following:
<br />
1 - VtChChartType2dBar<br />
3 - VtChChartType2dLine <br />
<br />
MSChart1.SetColumnCount(2);<br />
MSChart1.SetColumn(1);<br />
MSChart1.SetChartType(1);<br />
...<br />
<br />
MSChart1.SetColumn(2);<br />
MSChart1.SetChartType(3); <br />
Didn't work, it affects both series. So, both of them become lines.
I also tried this:
<br />
1 - VtChSeriesType2dBar<br />
6 - VtChSeriesType2dLine <br />
<br />
MSChart1.SetColumnCount(2);<br />
MSChart1.SetColumn(1);<br />
MSChart1.SetSeriesColumn(1);<br />
MSChart1.SetSeriesType(1);<br />
MSChart1.GetPlot().GetSeriesCollection().GetItem(1).SetSeriesType(1);<br />
...<br />
<br />
MSChart1.SetColumn(2);<br />
MSChart1.SetSeriesColumn(2);<br />
MSChart1.SetSeriesType(6);<br />
MSChart1.GetPlot().GetSeriesCollection().GetItem(2).SetSeriesType(6); <br />
No effect at all. Did I miss something or it's not possible at all?
I apprciate your help.
Regards,
Martin.

I have been exploring MSChart for sometime now and I have never come across the ability to have some of the chart bar and some of the chart line. I don’t think it is possible at all.
Let me know if you find differently....

I am an avid Visual Basic programmer and I would like to know what the advantages of using Visual C++/MFC are over Visual Basic.
For what kinds of scenarios can you not use Visual Basic?
