You *may* be overcomplicating the issue.

You have CADoc, which hold CABmp.

You have a command IDC_CROP which you want
to pop up a box, input some coords, and crop
the bitmap.

In header.

class CADocument : public CDocument
{
    ....
    CABmp m_Bmp;
    ....
    afx_msg void OnCrop ();
};

In Cpp

...
// Message map
ON_COMMAND(IDC_CROP, OnCrop)
...

// Function
void CADoc::OnCrop ()
{
    // Initialise the dialog.
    CADlg dlg (AfxGetMainWnd ());
    dlg.m_pBmp = &m_ABmp;
    dlg.m_rcBmp.SetRect (0,0, m_ABmp.GetWidth (), m_ABmp.GetHeight ());

    // Use the dialog to set a crop rectangle.
    if (dlg.DoModal () != IDOK)
        return;

    m_ABmp.Crop (dlg.m_rcBmp);

    SetModifiedFlag (TRUE);
    UpdateAllViews (); // Let the views know to redraw, using the new, leaner bitmap.
}

Just my thoughts. And there's a bunch to fill in...

UpdateAllViews was a good tip too !
It's just working perfect for me, much better then UpdateWindow amd Invalidate and this stuff!
But i had to use UpdateAllViews(NULL) to make it work...
No idea why but no I'm happy Smile | :)

Many Thanks again Iain,
Helge.

If you look at the docs , it defines UpdateAllViews as:

void UpdateAllViews( CView* pSender, LPARAM lHint = 0L, CObject* pHint = NULL );

The pSender is an optimisation if you are calling this function from
a View.

void CMyView::OnPropagateAChange ()
{
    CMyDoc *pDoc = GetDocument ();
    ....
    pDoc->UpdateAllViews (this);
}

That would redraw all views of that document except this one. I've never needed
to call with anything other than NULL, but I can see why you *might*.

The other parameters are useful for other views to work out *why* they need
redrawing, in case they only need to do a partial job. In a simple app, you
can leave them at their defaults.

Sorry I'm too dumb...
Now i find this nice faq here 6.2

http://www.codeproject.com/cpp/cppforumfaq.asp#cpp_runapp

where it's perfect described how to use global variables.
This point works just perfect for me.

So anyway thanks for your help,

Bind a EDIT CONTROL or DATACOMBOCONTROL

Bind a EDIT CONTROL or DATACOMBOCONTROL

Hi,

I am currently working on a program in VISUAL C ++ 6.0 (MFC) in which I would like to include an ADO DATA CONTROL 6.0 and a MS MASKED EDIT CONTROL or a DATACOMBOCONTROL .
The EDIT CONTROL is connected with the DATA CONTROL after program start-up.
All desired fields are indicated with the EDIT CONTROL.
Should the RECORDS SOURCE of the DATA Controls be changed or be limited during the runtime , the EDIT CONTROL looses the connection to the DATA CONTROL.

I have already tried everything REFRESH or BindProperty, unfortunately, without success.
I could not find a Solution to this problem or topic even in the Internet.
I would be thankful for a hint or for your assistance.

Listen in on the messages your window is recieving (Spy++ should work): note the differences between the messages recieved from clicking on the taskbar button, and those recieved when clicking on the menu. If they're the same, then your app probably has some problems pumping messages in a timely manner.

Attempting to compile my first IDL I keep getting the following error( using Visual Studio 7.1):-

Corba_Square error PRJ0019: A tool returned an error code from "Invoking TAO_IDL Compiler on c:\ACE_wrappers\Tao\examples\Simple\Corba_Square\Corba_Square\Square.idl"

The IDL compiles and generates the files when included in an example project supplied. I have checked all the settings and cant find anything to fix.

Does anyone know how to get rid of this error.

I am just trying to setup a project that can be used as a starting point for other projects (all the build, compiler and linker settings in place etc).

where N's are nodes that can be expanded.
Please ignore the dots they are for just making allignment.

Exporting resources in Visual Studio 6.0

Hi.
I’m going to rebuild an Dialog based VC++ project into another. I would like to export and import some dialog resources between the two projects. Any idea how to do that except for cut and past in the .rc file manually…

Open up the project
select Dialog Resource from the tree
COPY
then close the project
Open the Destination project in the same studio window
Goto the Resource tree
PASTE

Trick is to do this in the same Studio window (not two windows opened and copy from one and paste in other)

hope it helps Big Grin | :-D

Even easier.

Open up new project.
Switch to resource view.

Then load in previous rc file.
The old resources appear in the workspace.
Now right drag them to the new project,
and pick "Copy" from the popup menu which appears.

Nice and easy for several resources.

Hi all:
I have a bunch of .wma files which is in "C:\Downloads" folder, and I copy them to another folder. So now there has two folders which have the same content concerning the .wma files.

What gets it really strange is that in details view within Explorer they have totally different amount of columns. In "C:\Downloads" folder these .wma files has lots of column such as "Artist", "Album", "release year" etc,. But in the other folder it only has "Type" and "modification time" two columns. How this difference could be happened since there's no environment differences, I really eager to know!
Thanks!!!

You can set folder details on a per folder basis,
just right click on the listview header in explorer and select what you want to see.

You can switch on and off the columns that you want to be displayed via the menu item 'View->Choose Columns...', in Explorer. Or right click on the column header and select the appropriate column information.

'Open' Dialog

Hi all,
Can anyone tell me if it is possible to customise the 'Open' dialog so that the user can select a Folder to 'open' instead of a file?

Also on a normal 'Open' dialog is it possible to disable the browse options so I can 'force' the user to select files from only the current location?

many thanks,
Andy

to select a folder instead of a file, change the flags you pass the open dialog by the OPENFILENAME structure.

to disable the "browse location" functionnality, i don't think it is possible.
