if you are using the MFC class wizard you can double click on the button in the resource editor and it will add a handler for you (you are looking to get an ON_BN_CLICKED handler) Inside the handler declare and instance of the new dialog and away you go

just to clarify, is this assuming I have created a class for the new dialog as well?

and then you are saying to double click on the button in the old dialog and declare an instance of the new dialog?

I think I am creating too many classes, so please just clarify for me where and for what I am creating the classes, thanks!

BEGIN_MESSAGE_MAP(CMyMainDlg, CDialog)
ON_BN_CLICKED(IDC_BROWSE_PATH, OnBnClickedBrowsePath)
END_MESSAGE_MAP()

void CMyMainDlg::OnBnClickedBrowsePath()
{
CAnotherDialog dlg;
dlg.DoModal();
}

CMyMainDlg is the dialog for my main application...CAnotherDialog is the new dialog that I want to bring up on the button click.

hope this helps

Hope I understood your question
if you want to run another dialog use m_yourdialog.DoModal() or m_yourdialog.Create

I have a picture control on a dialog app.
Anybody know how to play a video inside that picture control.
I can play video using a default player like media player no problem, but i would like that video to be played from my app on my picture control.

Is there some sort of plugin or active x control that i can use?

Hey guys,

I am trying to study how functions with POINTER PARAMETER WORKS. Does anyone know any link where I can study how Functions with pointer parameters work.

Thanks D'Oh! | :doh:

void ObjectRoot::classInit( RTI::RTIambassador* rtiAmb, const char* classIdStr )<br />
{<br />
   ObjectRoot::ms_rtiAmb = rtiAmb;<br />
   ObjectRoot::ms_classIdStr = classIdStr;<br />
<br />
   if ( ms_rtiAmb )<br />
   {<br />
      ms_classId = ms_rtiAmb->getObjectClassHandle( ms_classIdStr );<br />
   }<br />
}

They work just the same as any other function does. When calling them, simply pass the variable's address instead of its actual value.

expanding environment strings

Has anyone written any code to expand a string with embedded environment variables in it, e.g.
%systemroot%\system32\drivers\etc\hosts

.. to form a literal string (as required by functions such as CreateFile()):

c:\windows\system32\drivers\etc\hosts

?

Many thanks.......

cheers,
Neil

you'll probably have to convert that HBITMAP it into a JPG or TIFF or whatever format PDFs can handle.

I am using a CMSChart. When I want to save this thing as a file I have to copy the chart into the clipboard as a bitmap and then I can bring it out of the clipboard into an HBITMAP. From there I can save it as a bmp or a jpg. But then the user can easily go into paint and try to change the contents. If I could put the HBITMAP into a pdf then the average user will not be able to change or manipulate the picture.
