I want to make a MS Outlook Add-in so I acces and view mail accounts that exist on a HTTP server.

The add-in part (which is my subject in the fist place!) is for a a windows program and therfore not suitable for the web dev forum.

The protocol I should use for talking to an HTTP server can be found somewhere in the big pile of knowledge they call RFC's. So you don't need to give me an technical explanation about it...

thanks for your time.

MFC and the CDocument pointer

Hi all,

Does anyone know the correct, or at least best, way to access a solutions' document object instance from a modal dialog? I thought creating an instance of the new dialog, then having an member function of that instance set a pointer within the instance to the document instance (from the view object instance using the GetDocument() function), but I wondered if there was a way to directly access a pointer from the dialog?

Any help would be much appreciated.

Thanks.

Modify the dialog's constructor to include a CDocument* parameter. Then construct the dialog like:

CMyDialog dlg(this);
dlg.DoModal();

This assumes the dialog is created in some document method. If the dialog is created in the view, you can use:

CMyDialog dlg(GetDocument());
dlg.DoModal();

Dialog box on program start

How do you display a dialog box once the main window of a program has already loaded up. I put created a dialog box at the end of CMainFrame::OnCreate but the dialog box appeared before the window loaded.

Any help would be greatly appreciated.

Thanks

Put the dialog box launch code into the application's InitInstance routine. Call it after the execution of pFrame->ShowWindow(SW_SHOW), and the dialog box will pop up right after then main window has been displayed.

I have a program where we would like to have a large translucent window placed on top of the program's main windows. The problem is that this new window captures key presses and mouse events. Is there any way to set thing up so that any user interaction is send directly to the views underneath?

You need to forward the messages to the correct windows manually.

The mouse is easy - handle WM_NCHITTEST and return HTTRANSPARENT. Not sure how to ignore the keyboard though.

I Googled the HTTRANSPARENT return value, and they mention another window style called WS_EX_NOACTIVATE, that looks like it may take care of the keyboard. I'll have to experiment to find out.

ITask->Run() always returning S_OK

Hello,

I created a job for task scheduler but I didnt set the password, so the job will never be executed.

From I app I executed the job. The ciode is as follows:

code:--------------------------------------------------------------------------------
ITask *task;
hr = m_pITS->Activate( wjobname,
IID_ITask,
(IUnknown**) &task);

if ( FAILED ( hr ) )
return;

hr = task->Run();

if ( hr != S_OK ) {
MessageBox( m_Hwnd, "Could not execute job.", MAIN_APPNAME, MB_ICONERROR | MB_OK );
} else {
MessageBox( m_Hwnd, "Job executed successfully.", MAIN_APPNAME, MB_ICONINFORMATION | MB_OK );
}

task->Release();
--------------------------------------------------------------------------------

The problem is whether the job was executed or not (it is not executed coz I didnt give the user password) the function is always returning S_OK. So whatever may be the result I am getting the messagebox "job executed successfully".

Is it normal?

Karam

If you look in MSDN, you'll see:

"A return code of S_OK means that the request to run the work item has been made; it does not mean that the work item has started running. There may be a delay of a few seconds after Run returns before the work item actually starts running.

To determine whether the work item is running, call IScheduledWorkItem::GetStatus."

So, you're good checking that it was scheduled, you need to go further:

hr = task->Run();
 
if (SUCCEDED(hr))
{
   //  check its status
   HRESULT  status;
   BOOL   started = FALSE;
 
   while (TRUE)
   {
      ::Sleep(250);   //   give us some time

      hr = task->GetStatus(&status);
 
      if (FAILED(hr))   break;
 
      if (SCHED_S_TASK_RUNNING == status)
      {
         started = TRUE;
 
         break;
      }
      else if (SCHED_S_TASK_READY == status)
         continue;
      else
         break;   //  could not schedule
   }
 
   if (started)
   {
      MessageBox(m_hWnd, "Job is running", ...);
   }
   else
   {
      MessageBox(m_hWnd, "Could not execute job", ...);
   }
}
else
{
   MessageBox(m_hWnd, "Could not start job", ...);
}
 
task->Release();   //   we're done with it

MFC and Drop Down Lists

15-Mar-04 7:15

Hi all,

Does anybody know why my drop down list won't drop down?

I've added items to it in the OnInitDialog overide (which calls the same CDialog function beforehand btw) and i can scroll through them using the keyboard. However, when I click the drop down button, the list doesn't appear - just a very small no. of horizontal lines appear below the text display window.

Can anybody help?

Thanks
Paul

I just had a brain-wave, and it worked.

The reason this was occuring was because when I created the control in the dialog editor, i only specified a control height which was that of the actual window for the combo box. I did not anticipate that windows would limit the actual drop down list to this space!!

It's silly things like this that hinder application development Frown | :(

.. Live and learn i guess Smile | :)

Hi, please help mi with this problem. When compile my project it compiles all cpp files (not only changed one). When pressing F5 it wants to build it all and writes that obj files are not up to date or does not exist. This is happening over and over again even if i dont make any change to code. Do u have any suggestion why this is happening? - it happend accidentaly (i quess) after 3 months workings with the project ... Thanks

You could try loading up the workspace/solution, then doing a complete rebuild. Then close the workspace/solution, and close the IDE. Then restart, and reopen the IDE. This might fix the problem.

The actual problem persists in the project database. On a MS VC++ 6.0 platform, deleting the project database file might resolve the issue.

This usually happens when a header file has a modified date in the future. So check your system clock and the dates on any header files in your project.

How to draw a line in Edit box?

Hello everyone. I want to draw edges for an Edit box. But I have to draw the lines inside the Edit box, because the edit box is too big. I tried to change the size of the Edit box, but I cannot make the height any smaller. The problem is that the line in the Edit box will be blocked by the Edit box. I tried to set the edit box to transparent, but I still cannot the lines.
Any idea about how to fix this problem?
Thanks a lot in advance.
