from Font Name and Font Size ==> TextWidth and Textheight ??

31-Aug-09 17:56

This happens because the dialog background and the button face have the same color value.
You could change the background color of the dialog so that it is slightly different from that of the button face.
Now you can specify the dialog background color as the second parameter to SetLayeredWindowAttributes.
You can change the dialog background color by handling the WM_CTLCOLORDLG[^] notification or if you're using MFC you can use CWinApp::SetDialogBkColor[^] function.

Question about RichEdit: the style of underline

31-Aug-09 18:03

You can use the GetTextMetrics[^] function to get the font height and width.
First get a handle to the font using CreateFont[^] or CreateFontIndirect[^].
Then create a device context using GetDC[^] and select the font into the device context using SelectObject[^].
Now you can use GetTextMetrics on the device context handle.

Hi, every one:
I have a problem with the underline style of richedit.let me descrip it in detail:
1,I input "abc" in richedit.
2,Then, i set only "c" with underline style."ab" remains the old style.
3,I select "abc" and set the bold or italic style to all of them.
4,"abc" has the style of bold or italic, and all the three characters have the underline style.This is confusing.The reasonable result is only the "c" has the underline style.

the code snippet i use is:
//set underline style
INT nStart, nEnd;
SendMessage( EM_GETSEL, (WPARAM)&nStart, (LPARAM)&nEnd, NULL );

CHARFORMAT2W cf;
ZeroMemory( &cf, sizeof( cf ) );
cf.cbSize = sizeof( cf );
SendMessage( EM_GETCHARFORMAT, SCF_SELECTION, (LPARAM)&cf, NULL );

cf.dwMask |= CFM_UNDERLINE;
cf.dwEffects |= CFE_UNDERLINE;
SendMessage( EM_SETSEL, nStart, nEnd, NULL );
SendMessage( EM_SETCHARFORMAT, SCF_SELECTION, (LPARAM)&cf, NULL );

//set bold style
INT nStart, nEnd;
SendMessage( EM_GETSEL, (WPARAM)&nStart, (LPARAM)&nEnd, NULL );

CHARFORMAT2W cf;
ZeroMemory( &cf, sizeof( cf ) );
cf.cbSize = sizeof( cf );
SendMessage( EM_GETCHARFORMAT, SCF_SELECTION, (LPARAM)&cf, NULL );

cf.dwMask |= CFM_BOLD;
cf.dwEffects |= CFE_BOLD;
SendMessage( EM_SETSEL, nStart, nEnd, NULL );
SendMessage( EM_SETCHARFORMAT, SCF_SELECTION, (LPARAM)&cf, NULL );

Is there any bug in my code?please help me.

I solved this problem today just now, the CHARFORMAT works. it is confusing too for me.
Is this a bug of richedit?

Hallo, i have an SDI-Application it is View class derived directly from CView, i need tob e able to change the output in it or to move the cursor with ctrl+pos1 or ctrl+end .Important: I can not use the class CRichEditView instead of CView to drive the View of my application. Thanks.

The text you can change with SetWindowText[^].
You can move the blinking cursor using SetCaretPos[^].

The problem is i do not have a blinking cursor., because this is a view derived from CView calss.

Did you try calling SetCaretPos?

And what about the CEditView[^] ?
If you implement directly from CView, you don't have any support for text (so, no cursor neither) or you will need to implement it yourself.

You need to do what ? a text editor ? and you cannot use either CEditView or CRichEditView ?

i need to print out the results of a database query, a class derived directly from CView is the only suitable possible solution till now i had before classes derived from CRichEditView and CEditView buut i hhad a lot of disadvanteges and ristrictions with them.

Stick an edit control in the view, occupying all of the view. (Which is, for all intents and purposes, what CEditView does, so why not use it?)

Why? This restriction severly limits, if not eliminates altogether, your options.

I dont think, it is good to use CView instead of CEditView or CRichEditView.
If you can derive a class from CView then you have handle SetCaretPos, SetWindowText and all to get the text support as suggested by earlier posters.

1/ Your question isn't really about SDI - it would be equally true from MDI too.

2/ If you're not allowed to use a Richedit control, maybe just a simple CEDitView?

3/ If you can;'t use that... then how about:
Crystal Edit - syntax coloring text editor[^]

It's not trivial to use, but I've used it for an in-program script editor with syntax colouring in the past to good effect.

Good luck!

how to use external function in a dll from c

First off, you should use CScrollView, rather than CView.

Secondly, you need to either register a custom window class with a custom cursor and override the PreCreateWindow method (preferred), or handle WM_SETCURSOR messages and call SetCursor() with the proper cursor handle, previously loaded in your init code (will flicker).

onwards and upwards...
