So you are wanting to change the second row, correct?

Just out of curiosity; Have you inserted any item in list control, before setting text? Or there are items present in control ?

initialize j with 1 and check.

Thank You.

Hi
I have two edit controls , 1 OK button and 1 Cancel Button.The code for the first editbox's EN_KILLFOCUS event is as follows:
void CTrial1Dlg::OnKillfocusEdit1()
{
// TODO: Add your control notification handler code here
CEdit *pEdit;
CString str;
double d1;
GetDlgItemText(IDC_EDIT1,str);
if(str.CompareNoCase(_T(""))!=0)
{
d1=_tcstod(str,NULL);
if(d1 > 3)
{
AfxMessageBox(_T("Greater than 3.Enter less than 3"));
pEdit = (CEdit *)GetDlgItem(IDC_EDIT1);
pEdit->SetFocus();
}
}
}
when I enter a number greater than 3 the message is displayed.As long as I press "OK" the message will be raised.The message will be raised even if I press "OnCancel".
My requirement is when the message is displayed and if I press the "Cancel" button the dialog should end.As I am using setfocus(), how can I do this?
Thanks in advance.

Wouldn't it be better to override OnOk() and OnCancel() ? So that in OnOk() you can check if the string is correct or not. If not, don't call CDialog::OnOk() so that the dialog won't be closed (and display a warning message).
I find this solution 'better' because the user won't have a message everytime he does something in the dialog, only when he wants to click on the ok button.

Thank you .
Actually I have many such edit controls where each one has a validation.So as per my requirement the data should be validated when the focus is lost from the edit box and the dialog should end when the cancel button is pressed instead of postponing the checking of validations until the ok button is pressed.

I don't know if that will work but in your KillFocus function, you can retrieve the current window that has the focus with CWnd::GetFocus. I don't know if that will be already the Cancel button, you have to try. Then, you can get the ID of the 'control' with GetDlgCtrlID. If that matches with the id of your cancel button, then leave the KillFocus function directly.

Of course it will. That's because the edit control has lost focus. The code is doing exactly what it is suppose to.
A better solution is to handle the EN_CHANGE notification, and if the value in the edit control is ever greater than 3, disable the OK button. Doing validation is response to EN_KILLFOCUS is just the wrong approach.

You need to find the header in which this is defined, and then include it in your c file.

I know, but the header file must be if_ether.h or ether.h or if.h and the ETHER_TYPE_NULL don't existe in all of this files. What is the value for this constant??
thanks

I've spent a few minutes looking for it, and did not find. What kind of file uses this ?

Hi Everybody.
Please, I want to know I can draw a line on my dialog.
I really want to draw a chart on my dialog. The chart will have 2 axes (x, y).
Thanks.
|
|
|
|
|
Maybe you can take a look at the article I wrote (link in my sig). This is a chart control and maybe it can do what you are looking for.
|
|

|

probably custom control is the way to go, if you search here in cp you will find many good tutorial on how to dothat.

Do you know how to work with DC's
Get the dc of the dialog as
HDC hdc=::GetDC(m_hWnd);
and then use the line drawing functions to draw on the dialog through the DC
Once you are done with the dc release it.
Here's a sample code
HDC hdc=::GetDC(m_hWnd);
MoveToEx (hdc,0,0,NULL);
LineTo (hdc,100,100);
::ReleaseDC (m_hWnd,hdc);

Somethings seem HARD to do, until we know how to do them.

In WM_PAINT you can use from dc for draw line
CPaintDC dc(this); dc.MoveTo dc.LineTo(...) Is your purpose?

Show the code of the function (declaration and definition) and the way you declare it in VB.

On XP this can be done by simply holding down the Shift key when opening a folder whose view is already set to thumbnails.
Is this possible in win2000 by using MFC?
Thanks in Advance.

Hi all,

If you want to highlight a particular row, try this in your OnCustomdrawList function:
COLORREF crText, crBkgnd;
if ( CDDS_ITEMPREPAINT == pLVCD->nmcd.dwDrawStage )
{
if ( (pLVCD->nmcd.dwItemSpec % 3) == 2 )
{
LOGFONT lfFont;
CFont *pFont = GetFont();
_ASSERTE( pFont );
pFont -> GetLogFont( &lfFont );
CFont m_fBFont;
m_fBFont.CreateFontIndirect( &lfFont );
SelectObject(pLVCD->nmcd.hdc,m_fBFont);
crText = RGB(255,0,0);
crBkgnd = RGB(255,255,0);
pLVCD->clrText = crText;
pLVCD->clrTextBk = crBkgnd;
}
*pResult = CDRF_NEWFONT;
}
}
To color the background of a particular column, try this:
if ( (CDDS_ITEMPREPAINT | CDDS_SUBITEM) == pLVCD->nmcd.dwDrawStage )
{
COLORREF crText,crBkgnd;
if (0 == pLVCD->iSubItem)
{
crText = RGB(128,0,225);
crBkgnd = RGB(247,241,202);
}
else
if (1 == pLVCD->iSubItem)
{
crText = RGB(0,128,0);
crBkgnd = RGB(247,241,202);
}
pLVCD->clrText = crText;
pLVCD->clrTextBk = crBkgnd;
*pResult = CDRF_DODEFAULT;
}
