hi
is it possible to send a BSTR to a method expecting a _bstr_t?

void function(_bstr_t string);
BSTR BSTR_string;
function(_bstr_t(BSTR_string,true));

The bool argument to the _bstr_t constructor specifies whether you want to copy the string or simply attach it to the _bstr_t object you're creating.

The task is to create non-title dialog which allows user to move it arround the desktop.
As we all knew, user can move the normal dialog by click left button and drag the mouse while it is in the Title area. My dialog have no title, how I can perform the task.

I have tried to handle events WM_LBUTTONDOWN and WM_MOUSEMOVE in the WindowProc procedure of the dialog.
I can move the dialog, but the problem is:
The dialog can't move smoothly. It is flicking
Does any one help me to handle the task better?

Thanks very much

Add a handler for WM_NCHITTEST and just return HT_CAPTION.

UINT CMyDlg::OnNcHitTest(CPoint point) 
{
  return (HTCAPTION);
}

I been working on this clock replacement program because I never find
any open source ones.

update/refresh my systray to fit my clock replacement.

the AIM icon.
http://69.50.187.114/~area51/after.gif

GDI/OpenGL or DirectX?

What would be the best method for printing to the screen without flickering? I tried using GDI but it still flickers.

I want to *draw* lines to the screen. The only prob is that I want it intended to be run with a DirectX game which flickers every second.

What would be the best way to do it?

Did you init the richedit control with AfxInitRichEdit2()?

Re: RichEditCrtl in dialogue doesn't work

Tom Archer11-Jun-05 13:58

Depending on the version of the richedit control you're using:
AfxInitRichEdit[^]
AfxInitRichEdit2[^]

Strange edit control problem

Hi everyone,
I'm creating an edit box as child window of a list view ctrl to edit a subitem's text. When the edit box is created, it is invisible, although it has the WS_VISIBLE style set... I have to press some key to change the text of the edit box to make it visible.
What is wrong?

Regards,
Alex

Add the WS_BORDER style, debug the CreateWindow function, if no error succed, and the problem persist, try using ShowWindow function.

I did, but that didn't change anything Frown | :(

CreateWindow does succeed, but the control is still hidden until I press a button to change it's text.

Don't try it, just do it! Wink | ;-)

Hi,
Try the SetWindowPos() function,and set its position on top of your listbox:

YourEditBox.SetWindowPos(&CWnd::wndBottom, 0, 0, 0, 0,
                         SWP_NOMOVE|SWP_NOSIZE);

CString GetExePath()
{
	CString str;
	TCHAR szEXEPath[MAX_PATH];
	
	GetModuleFileName ( NULL, szEXEPath, MAX_PATH );
	
	str = szEXEPath;

	CString s1,s3;

	int pos = str.ReverseFind( '\\' );
	
	CString s2;

	s2 = str.Left( pos+1 );
	return s2;
}

This should get you started.
