Re: attach an icon to mouse cursor

Thats right and you cant select a bitmap into a dc more that one time and I said previous you replace new object with current object (return value of SelectObject).

I have loaded images in the Thumbnail dialog and also i have added background color. But in vertical scroll the dialog is not getting repainted.Can anyone please help me. I have enclosed the source code here.

<pre>

CBitmap Background;
CBrush BrushHol;
CSize bitmapSize;

In OnInitDialog,
ShowWindow(SW_SHOWNORMAL);
Background.LoadBitmap(IDB_BITMAP1);
BITMAP bm;
Background.GetBitmap(&bm);
bitmapSize = CSize(bm.bmWidth, bm.bmHeight);

In onpaint,

CDC dcMemory;
dcMemory.CreateCompatibleDC(cdc);
CBitmap* pOldbitmap = dcMemory.SelectObject(&Background);
CRect Client;
GetClientRect(Client);
const CSize sbitmap = bitmapSize;
cdc->BitBlt(0,0,sbitmap.cx,sbitmap.cy,&dcMemory,0,0,SRCAND);
dcMemory.SelectObject(Background);

In vertical scroll,

if( Background.m_hObject != NULL )
{
InvalidateRect(Client,TRUE);
}

DBCS problem

When our code, which is not Unicode, is used on a system with DBCS enabled (e.g., Japan), the typed text is not being retrieved from the edit controls properly. For lack of a better-formed question, must I do something special to the edit control (styles) or the code that retrieves the text from that control so that I get the correct text?

Thanks.

What kind of method to get the text of edit control?
GetWindowText?

What kind of text in the edit control?
ANSI or Japanese character?

There's nothing special.

Re: Using CMFCStatusBar class How do you Set the Text for a Label(dynamically)

4-Dec-08 3:42

I've tried SetWindowTextA(...,....) and SetDlgItemTextA(..,...) but nothing works. There must be a command somewhere where you can change on-the-fly messages contained in a Window Pane of a StatusBar. Does someone know how? I'm using VS2008, MFC.

Yes that works! I don't know why I didn't see that command, but I'm glad you elightened me. Another question: Is there a way, to "on-the-fly",to enlarge a particular pane so that it fits the needed space for new text?

Larry, 50 minutes has passed between your posts. It would take you less than 5 to go read the documentation on msnd.microsoft.com for the class. Logically it's more productive for you to read the documentation than wait for answers in internet forums. So the 50 cent question here is, why do you refuse to read the documentation?

Okay, I checked out MSDN Lib rary on CStatusBar class. I found nothing explaining what command to enlarge the Pane for the new Text. Do you know where I can find that out?, or better still, what that command might be?

CStatusBar is not the same class as CMFCStatusBar.

I noticed in MSDN under CMFCStatusBar that there is a SetPaneWidth() but How do you set a particular Pane's width using that command. if my pane is ID_PANE3 how would I set the width on it to fit the length of a CString? (I sure wished they would show examples of this stuff.)

Yes I see that; but If my pane is ID_PANE3 how would I get focus on it and do this CPane::AdjustSizeImmediate() . How do I set the length(not Width) to equal(in pixels) to a CString?
(An example would be great.)

What i'd try is to call that on the MFCStatusBar itself with TRUE as parameter, so something like:
my_mfc_statusbar.AdjustSizeImmediate(TRUE);

I find that using a function with various arguments uncovers a lot about its usage. Try something like:

mfcStatusBar.SetPaneWidth(ID_PANE3, 500);

It crashed because the ID_PANE3 is not supposed to be there, rather the nIndex of the Pane is supposed to be there. Works okay if set to 250 rather than 500. Thanks David.
