Don't worry about. Just kidding with my old friend Hamid.
BTW try to start insertion from column 0, as suggested by Jörgen Sigvardsson.

My bet is that because you inserted a new column at 1, an empty zero width column was created at column 0. The inserted item is there, but it's in the 0th column, which you can't see. Try inserting columns from index 0 instead! Smile | :)

Or add SubItems. Good bet indeed.

<br />
m_users.InsertColumn(0,"a",LVCFMT_CENTER,150,0);<br />
m_users.InsertColumn(1,"b",LVCFMT_CENTER,50,0);<br />
m_users.InsertColumn(2,"c",LVCFMT_CENTER,150,0);<br />

LVITEM lvi;<br />

lvi.iItem = 1;<br />
lvi.iSubItem = 0;<br />
lvi.pszText = _T("Hi");<br />
m_users.InsertItem(&lvi);<br />

on compilation & execution, still nothing on List !
Let me give you some more details, I might have done something wrong there...
I have used VC++ Wizard to create my project (i m new to vc++)
Then I added List control to a Dialog box
Then changed its properties to ->Report
Then created a m_users variable
Then I have inserted 4 columns to it
Everything works fine till here...
Now I try to add some data to it, & nothing happens on the list !
plz friends, guide me in this....

Were you cheating about the effective overload of the InsertItem method called?
Suspicious | :suss:

Anyway:

Some suggestions:
(1) Change

tina- wrote:
m_users.InsertColumn(0,"a",LVCFMT_CENTER,150,0);
m_users.InsertColumn(1,"b",LVCFMT_CENTER,50,0);
m_users.InsertColumn(2,"c",LVCFMT_CENTER,150,0);
m_users.InsertColumn(3,"d",LVCFMT_CENTER,150,0);

m_users.InsertColumn(0,"a",LVCFMT_CENTER,150,0);
m_users.InsertColumn(1,"b",LVCFMT_CENTER,50,1);
m_users.InsertColumn(2,"c",LVCFMT_CENTER,150,2);
m_users.InsertColumn(3,"d",LVCFMT_CENTER,150,3);

(2) Change

tina- wrote:
lvi.iItem = 1;

lvi.iItem = 0;

(3) Add, before calling InsertItem method

lvi.cchTextMax = _tcslen(_T("Hi"));

Try to further populate the List, for instance, add

BOOL fSuccess;
INT nItem;
fSuccess = m_users.SetItemText(0,1,_T("foo1");
fSuccess = m_users.SetItemText(0,2,_T("foo2");
fSuccess = m_users.SetItemText(0,3,_T("foo3");
nItem = m_users.InsertItem( 1, _T("boo"));
fSuccess = m_users.SetItemText(1,1,_T("boo1");
fSuccess = m_users.SetItemText(1,2,_T("boo2");
fSuccess = m_users.SetItemText(1,3,_T("boo3");

Checking always, with the debugger, the return values.

My resources are near to end...

Edit accelerator in VC6's resource editor and rebuild all, nothing changes

I add an accelerator and rebuild all, it doesn't take effect.
Then I modify the exist Ctrl+O to Ctrl+D and rebuild all, it doesn't take effect edither. Ctrl+O still works.
What the matter?

rare flick problem [Updated]

followait

11-Jan-08 20:30

I rebooted my computer, no flicking now...

It's a program using GDI+, it doesn't flick yesterday, but it flicks now, even worse, it causes other irrelevant programs' windows flicking.
I installed sql server 2000 before I found it flicked again.
BTW, I always call Invalidate(FALSE) or InvalidateRect(&rc,FALSE) in the program.
Here is the code in OnDraw:

Graphics g(pDC->m_hDC);
g.SetTransform(&m_Matrix);
g.DrawImage(m_pMemImage,0,0);
g.ResetTransform();

if (m_pCtrlBoxMoving) {
	DrawCtrlBoxFrame(m_pCtrlBoxMoving,&g);
} else if (m_pCtrlBoxSizing) {
	DrawCtrlBoxFrame(m_pCtrlBoxSizing,&g);
} else if (m_pCtrlBoxRotating) {
	DrawCtrlBoxFrame(m_pCtrlBoxRotating,&g);

CStatic::OnPaint() problem

hanlei000000000911-Jan-08 20:24

hanlei0000000009

11-Jan-08 20:24

Hi, All

I overloaded CStatic::OnPaint()

<br />
class myStatic : public CStatic<br />
{<br />
...<br />
}<br />
<br />
void myStatic::OnPaint()<br />
{<br />
<br />
	static bool bb = true;<br />
<br />
	CPaintDC dc(this); <br />
	CBitmap   myBitmap;  <br />
<br />
	if (bb)<br />
	{<br />
		// print  1.BMP<br />
		bb = false;<br />
	}<br />
	else<br />
	{<br />
	     // print  2.BMP<br />
		bb = true;<br />
	}<br />
  <br />
}<br />
<br />

I definition a myStatic object in main dialog

<br />
class CMyDialog : public CDialog<br />
{<br />
 private:<br />
  myStatic m_picture;<br />
  void changePicture();<br />
}<br />
<br />
void CMyDialog::changePicture()<br />
{<br />
 m_picture.SendMessage(WM_PAINT,0,0);<br />
     this->SendMessage(WM_PAINT,0,0);<br />
}<br />

When run to changePicture(), can run to print (1.BMP or 2.BMP) , but the picture not real changed.

And then, if the main dialog had changed, the picture was real changed.
So, how can make the picture is real change at changePicture() is run.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
