You can not use any functions that rely on the hWnd been set within the constructor of a CWnd derived class.
If you look at the code you will see that the pWnd is set but the hWnd is NULL.
The hWnd is set as the control is created.

I'm running a C program in visual C++ which uses command line switches. How do I use these as I've never used them before, and don't know how to specify either the commands or the the underlying options.
TIA

Without knowing what application you are attempting to run I doubt we will be able to help.

Hi - thanks for responding anyway. I think I've just made a breakthrough myself while looking for a way to explain it better.
Thank you

command line options can be found at
Project>Settings>C/C++
You can see the project option are set there.
For c programs use the /Tc key and for c++ programs use /Tp key.
You can get complete list of compiler options can be found in MSDN.
I believe most of these options can be set using GUI itself.

BOOL CDocument::OnNewDocument()

.............//created or not.

Both the CSingleDocTemplate and CMultiDocTemplate class contain this call:
AfxMessageBox(AFX_IDP_FAILED_TO_CREATE_DOC);
to inform the application user that it failed to create the document.
For development purposes (DEBUGING) they also produce messages in the Build results windows using:
TRACE0("CDocTemplate::CreateNewDocument returned NULL.\n");
The base CDocument::OnNewDocument() just does some intialization of existing variables. In a single document/view: this means you need to destroy any previous information your document is holding and reinitialize any needed variables. In a multiple document/view: this means you may need to initialize some data variables needed to store your data.
BOOL CMyEditDoc::OnNewDocument()
{
if( !CDocument::OnNewDocument() )
return FALSE;
if( !MyInitFunction() )
{
return FALSE;
}
return TRUE;
}
For both single and muli-doc application: The document object already exist before this member function is called, otherwize this function could not have been called ligaly. The document and the document object that holds it are 2 different things. Note: If this function fails (return FALSE) then any window created to view the data is automaticaly destroyed (the document object may also be destroyed).
A bit long winded, but I hope it helps a little.

Hi,
I am trying to port a vc6 coinstaller project (basically a DLL) to vc7. It compiles and builds correctly. The difference is that the new vc7 DLL does not display the property page for a particular device. The vc6 build is doing it correctly. I have coded an exception in the CoInstallerFunc but I see that the device Manager is not calling it.
I also posted this message to some MS discussion forums and I keep getting errors like "Your Passport session has expired. You need to sign in again before you can post to this group." I sign in and no change. I delete cookies, still no change. Looked on Google without success. So how do I post a new question to an MS newsgroup when this message appears? (It's ironic that I ask a discussion board on how to post to a newsgroup, but anyway...)

I don't have a ddk.where can i get it.pls advise.

The DDK is available from Microsoft. It comes as part of the MSDN subscription. I am not sure if you can download it without a subscription nor whether it is available alone. Try searching for DDK on www.microsoft.com[^]
Hope this helps you out.

I'm currently using a sample code can send text as well as image files as a attachment along with the Outlook Express mail.
However, my current requirement is to send image files that are embedded inside the mail and not attachments. I tried to create a code for this but of no success. Could someone give me some tips regarding this. Else if you have the sample code for the above, I would be grateful if you would send it to me.
Another problem I have is that when I send an HTML file (this file contains an image file inside it) as an attachment with the mail, I observe that only the html file and the image link has been sent to the recipient. I don't know a way to send the image file also with the html file. Please enlighten me regarding this.
