Re: how can use MFC in a non MFC win32 project

#include <windows.h> or #include <afxwin.h>

After that, the MFC classes should be available to your application.

From the MSDN

const UINT WM_TASKBARCREATED = 
    ::RegisterWindowMessage(_T("TaskbarCreated"));

BEGIN_MESSAGE_MAP(CMainFrame, CFrameWnd)
    ON_REGISTERED_MESSAGE(WM_TASKBARCREATED, 
                          OnTaskBarCreated)
END_MESSAGE_MAP(CMainFrame, CFrameWnd)

LRESULT CMainFrame::OnTaskBarCreated(WPARAM wp, LPARAM lp)
{
    VERIFY(InstallIcons());
    return 0;
}

BOOL CMainFrame::InstallIcons()
{
    NOTIFYICONDATA nid; 
    //
    // stuff nid with args
    //
    return Shell_NotifyIcon(NIM_ADD, &nid);
}

Hope you get the idea

If you want a fancy control, look at the Miscellaneous controls section on this site -
theres a whoooole bunch of graph / chart controls.

If you just want to "join the dots", look up Polyline in the MSDN docs.

Email Server Source Code

Hi

I am looking for simple source code that allows me to get E-mail from an ISP onto a PC and strip it and re-build it ( I need to find certain text in the message body and copy it into the subject line.) The program then needs to act as a server and allow another program to use POP3 to retrieve the mail, any ideas?

Cheers

Eugene

Instead of looking to others for a solution to your problem, try reading RFC 1939. I'm sure it'll answer most of your questions related to the POP3 protocol. Implementing POP3 into a program is a trivial task and I'm sure you'll agree once you know how it works.

Try doing a search on, um, codeproject with a phrase of pop3[^], and you get loads of
hits. If you have a specific problem, an author of an article you used, or this
forum may be to help.

Problem to access the excel sheet with different versions(Excel 2000, Excel 2002)

Member 7383647-Mar-04 19:26

Hi,
I have developed a small program to read the content from excel sheet in VC++. The developed program is working in Excel 2002 version, but it is not working in Excel 2000. I found that Excel 2002 having "_Application" class, but it is not in Excel 2000. In this project First I have included the "Excel.Exe" Type library. Then I changed the type library with "XL5EN32.OLB". Because this ".OLB" file is exist in both versions. Then I changed my code accordingly with the classes available in the OLB file. The classes I have included are "Application","WorkSheet","WorkSheets","WorkBook",WorkBooks","Range". While compilation time this project is ok. But it is giving the "Runtime" Error. Below I have mentioned the code I got the runtime error.

-----------------------

AfxOleInit(); //Initialization

Application app;
Workbook book;
Worksheet sheet;
Workbooks books;
Worksheets sheets;
Range range;
LPDISPATCH lpDisp;

COleVariant
covTrue((short)true),
covFalse((short)false),
covOptional((long)DISP_E_PARAMNOTFOUND, VT_ERROR);

if(!app.CreateDispatch("Excel.Application"))
{
AfxMessageBox("Unable to Create Excel Application");
return;
}

VARIANT var;
var=app.Workbooks(OleVariant("*.XLS")); //I got the RunTime error Here.
lpDisp = var.pdispVal;
books.AttachDispatch(lpDisp);

--------------------------------------------

var=app.Workbooks(OleVariant("*.XLS));

The above line is giving the problem. If anybody knows the solution to this problem, please reply me. Thank you very much.

Ramanan.

At the risk of asking a stupid question, what do you expect that line to do?

I'm assuming that you have a simple typo, and it should be COleVariant("*.XLS"), but that nicety aside, I think you need to understand what the method you're calling actually does.

app.Workbooks( VARIANT ) will return a Workbook object (strictly, a Workbook interface), and the value of the variant can be a numeric index into the collection, between zero and Workbooks.Count-1. It's a shorthand for app.Workbooks.Item(VARIANT). The value of the variant can also be a document name, such as "C:\Documents And Settings\Steve S\My Documents\vacation.xls".

There isn't, unless they've updated the model significantly since I last checked, anything that supports it being a wildcard.

I know all the automation stuff for Excel, Word etc has samples in VB, but I suggest you read the appropriate docs. It's not that hard to figure out. You might also search the MS site for a download called something like B2CSE. This is a simple VB automation to C++ automation conversion tool, and while it's not perfect, is really helpful in circumstances like this.

GetFocus() returns NULL

Hello,

Just wondering if any of you would know the answer to this:

For the win32 api function, ::GetFocus(), the docs say "If the calling thread's message queue does not have an associated window with the keyboard focus, the return value is NULL."

So how can you check if your application is active or not?

Thanks,

Swine
