AFAIK, your only option is iterating over all items and checking each with GetItemText.

Hi,

Can someone tell me how to access the progress bar in status bar from CView.

for example, the following code is not showing any activity in the progress bar Cry | :((

CMainFrame* cfm = (CMainFrame*)AfxGetMainWnd();
cfm->StatusBarMessage("Link Verification going on...");
for( int i=0; i<800; i++ )
{
Sleep(10);
cfm->m_ctrlProgress.SetPos(i);
}

StatusBar Message is shown, but not the activity in the progress bar.

thanx in advance...

Use Invalidate/UpdateWindow to refresh the progress bar. Your loop doesn't service message queue, windows do not repaint themselves.

You may have a CBitmap in an non-compatible format for your output DC, take a look at the bitmap section in my printing article.

Please help me, I want to show a Tooltip when the User point the Cursor to a FlexGrid-ROW. If searched a lot by I haven't found....

So I tried and found out that I must use the <ontoolhittest> MemberFunktion. The problem is, to fit the variables.

How can I get the Row, on which to Cursor points? How can I find the nID...
i

nt CMyFlexGrid::OnToolHitTest(CPoint point, TOOLINFO* pTI) const
{

pTI->hwnd = m_hWnd;
//
-->??? pTI->uId = ???????????????????????????;
pTI->lpszText = LPSTR_TEXTCALLBACK;
pTI->rect = rect;
return pTI->uId;

return CFlextable::OnToolHitTest(point, pTI);

Thank you for any help!

Hi
just implement it in your app's view-class. Just add a line in the OnInitialUpdate:

CMyView::OnInitialUpdate()<br />
{<br />
  SetWindowText("This is my child window title!");<br />
  CBaseClassView::OnInitialUpdate();<br />
}

Hope this helps!

You could try with GetParentFrame()->SetWindowText(...), but your title will be changed by MFC. To get this right, you need to override the following CMDIChildWnd method:

void OnUpdateFrameTitle(BOOL bAddToTitle);

In your implementation, call 'GetMDIFrame()->OnUpdateFrameTitle(bAddToTitle);' first, then set the caption with a call to AfxSetWindowText (reduces flicker).

Re: SendInput() compiler report "undeclared identifier"

SendInput is located between the following preprocessor directives:

#if (_WIN32_WINNT > 0x0400)
...
#endif

Define _WIN32_WINNT with value greater than 0x0400 before including winuser.h and you'll be OK.

Thank you for your reply.
I write the code according to you:
...
#define _WIN32_WINNT 0x0500
#include "winuser.h"
...
but it report the same error "undeclared identifier".
is there other reason?
Thanks again!

Place the #define in stdafx.h, before any #includes.

Button inside a listbox?

Moak18-Aug-02 20:24

18-Aug-02 20:24

Hi GUI coders,
I try to create a ownerdraw listbox which has a fixed button in the upper right corner. Fixed button means here, it always is at the same local position (drawn over listbox entries). Basically, it should look like this (o = button).

_______________
|            o ||
|              ||
|              ||
|              ||
|              ||
|______________||

I already have an ownerdraw CListbox class and an ownedraw CButton class (MFC). Now, how would I integrate my ownerdraw button? Can I use my existing button class (1. somehow one button dynamically created over the listbox)... or do I need to handle everything on my own (2. somehow inside my listbox class)??? At the end I'd like to have a new control. Thanks for any hint or ideas. Currently I have no idea how to start.

Thanks, Moak Smile | :)

PS: What's the idea of this control? When a user hits the new button I'll create a popupmenu showing some icons and the user can choose one. The icon will then be shown in the listbox (it's a output of a chat program).

This is easy. I'm assuming your app is dialog based, or CFormView based.

1. Create a class derived from CListBox ... eg CMyListBox. Does not need to be owner draw for this.

2. Add a member variable to CMyListBox "CButton *m_pButton"

3. Add an implmentation of CMyListBox::PreSubclassWindow :-

void CMyListBox::PreSubclassWindow() 
{
	// TODO: Add your specialized code here and/or call the base class
	
	CListBox::PreSubclassWindow();

	m_pButton = new CButton;
	m_pButton->Create(":o)",WS_CHILD | WS_VISIBLE,CRect(0,0,20,20),(CWnd *) this, 1);	
	
}

4. Use Classwizard to map your dialogs List box control to an instance of CMyListBox.

5. Bob's your uncle.

Can I just ask why your using new to allocate the object? Just declare it as CButton m_Button, call create as normal, and you have reduced the risk of a memory leak. Its also faster.

BTW, you also need to call DestroyWindow() on the button in the OnDestroy of the ListBox override class.
