TChar Buff in to a CString Variable.

C'tor of CString or assignement operator will take care of that.

e.g
CString csString(pCharArr);
or
Cstring csString = pCharArr;

Meaning that you can't do something like:

Of course. Why would you think it was even possible?

Have you tried using memcpy()?

I'll assume this is just bad English getting in the way of your actual intent. Otherwise, don't expect anyone to take you up on this. Creating an article is no small undertaking.

If you are simply wanting to know how to use such a control, have you Googled for:

CreateWindow("RICHEDIT_CLASS", ...);

Or at least looked here?

I have read that. But it has examples of how to do that. So with my lack of knowledge I wouldn't be able to read and do it Frown | :(

I feel nostaglic on C++. To go do MFC instead :\

So why not just look at what MFC is doing? You'll notice a lot of EM_xxx messages are actually being sent.

Its stated as Illegal operation attempted on a registry key that has been marked for deletion. (use Tools-->Error Lookup to see description of win32 errors).

You can use FormatMessage to see the description of the error, as in the following code excerpt (from MSDN)

LPVOID lpMsgBuf;
FormatMessage( 
    FORMAT_MESSAGE_ALLOCATE_BUFFER | 
    FORMAT_MESSAGE_FROM_SYSTEM | 
    FORMAT_MESSAGE_IGNORE_INSERTS,
    NULL,
    GetLastError(),
    MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), // Default language
    (LPTSTR) &lpMsgBuf,
    0,
    NULL 
);
// Process any inserts in lpMsgBuf.
// ...
// Display the string.
MessageBox( NULL, (LPCTSTR)lpMsgBuf, "Error", MB_OK | MB_ICONINFORMATION );
// Free the buffer.
LocalFree( lpMsgBuf );

If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Combo box in CListCtrl

I am working on creating a drop down combo box if user clicks on a column in a list control. I have got one document in the link: http://www.codeproject.com/listctrl/CustomizedReportListCtrl.asp

But the problem is CBS_DROPDOWNLIST style has been used in that combo list. But I want to make that combo box editable. CBS_DROPDOWN is not working. Could anyone tell me how to do that?

That article message board is better place to ask this question.

You need to be very clear instead of saying "not working", while asking there ,too.

I removed default hover behavior in my toolbar. Can I get it back?

Hi, I have a CToolbar and somehow managed to cause the buttons in the toolbar to not have a box drawn around them when the user's mouse is positioned over them. Is there an easy way to get this behavior back?

I don't know how I managed to remove this behavior, that's why I have no idea how to put it back in.

Thanks,

Max

I already have this style.

I think I know more about what the problem is now: My buttons are *disabled*. Is there a way in the toolbar editor to set a button to be enabled?

I see what is going on! If I do not assign the button an ID like "ID_APP_ABOUT", the button is disabled. It looks like the ID must match one of the symbols in the resource symbols list. I have two more questions about this:

How do I make a new symbol, should I be using a wizard?
How do I add an entry to the message map? (use a wizard?)

By this, I mean the list below

BEGIN_MESSAGE_MAP(MyApp, CWinApp)
ON_COMMAND(ID_APP_ABOUT, &MyApp::OnAppAbout)
// Standard file based document commands
ON_COMMAND(ID_FILE_NEW, &CWinApp::OnFileNew)
ON_COMMAND(ID_FILE_OPEN, &CWinApp::OnFileOpen)
// Standard print setup command
ON_COMMAND(ID_FILE_PRINT_SETUP, &CWinApp::OnFilePrintSetup)
END_MESSAGE_MAP()

Thanks, I will learn from a book I have

Redraw Controls

25-Mar-07 23:11

Hi everybody,

i still have a problem with the redraw of controls.

The Return-Key on a Grid provokes a switch of the view in the current Tab(of the TabControl)
The new view will be created, drawn, all ok.

I switch to another application (firefox for example) then i return to my application and the Grid is invisible. Sizing the frame provokes a OnSize and the all controls will be redrawn, the grid is already visible(drawn)

Now, i removed the Line "Grid->RedrawWindow(...);" from out the OnEraseBgnd-Handler.
The problem is solved, but now i have the initial problem :

At creation, the grid will be created and correctly drawn, then if a Thread has extracted all informations, the grid will be filled with the data.

Just at this time, the grid disappears.
It could be a problem of the grid, but i don't think so, because i have the same effect with textboxes.

The textbox which gets the focus during initialisation, will not be drawn Sigh | :sigh:

Does anyone has an idea?

Big thanks Smile | :)
