Hello,
I am writing an application that will provide the feature of "taking" a pixel color from any other window, currently displayed. When the user right clicks with the mouse on the desktop, taskbar, or the system tray for example, the color (RGB) of the pixel he has clicked on must be obtained.
Do you have any idea how this functionality could be implemented?
The real question is how could I obtain another window's DC (from which I could get the pixel), and the mouse coordinates when the user presses the right button on another window...
Thank you in advance.

My "?" was for the Greeeg's smiley. I did not understand what he meant about that.
But anyway, I agree that the link provided gives me the right clues for solving my problem, for which I thank Maximilien
I am sorry for the misunderstanding...

It was just Greeeg's way of providing a hyperlink. He used an image tag instead of an anchor tag.

How do I add an achor tag ?
How do I write a [code] section,
which appears in light yellow if I remember well
Is there a link that explains all of these things and others ?
Thanks !

Thank you,
I am realizing now that with Mozilla browser only the smileys appears, not the others.

No matter. You can insert <A>, < PRE>, and <CODE> tags manually.

Hi Guys,
Iam writing an MFC application with a dialog having a listbox control.
In the view header class,have the ListBox object as a member variable.
CListBox m_ListBox;
The questions I have are:
[1]How will I create a Listbox control
used the "m_ListBox.Create"- How will I pass the cDialog class as I have to pass a "pParentWnd parameter" which expects a CWindow object
[2]How to make the listbox control,Dialog & view class of the same size.
[3] Want to add 2 columns in the list box,a header row, with constant values.
1st column 2nd column
************* ***********
FixedLineNumber; 5
StartLineNumber; 10
NumberOfLines; 4
FixedLength; 15
CharacterLength; 10
CharacterOffset; 5
and fill the 2 columns with values as above.
the first column contain constant texts & the second coumn,I want to fill with values...
Any help is appreciated....

All MFC windows (including CDialog objects) derive from CWnd. Just cast it to CWnd in the create function

What do you mean? like as in the same size on the screen?

You are using the wrong control. Use a CListView control rather.
Cheers,

It is CListCtrl.
You can use these functions of the class
eg:
To add columns
m_ListCtrl.InsertColumn(1,"1st Column");
To add data to the control
m_ListCtrl.InsertItem(0,"Data");
m_ListCtrl.SetItemText(0,1,"Value");

How will I connect my view class which is derived from Cview to the control object,Co's I want to test the list control
Did as follows:
On the,"OnCreate" function of my view class,I did as follows
m_lstctrl.Create(WS_CHILD|WS_VISIBLE|LBS_STANDARD|WS_HSCROLL,
CRect(10,10,200,200),this, IDC_TEST);
m_lstctrl.InsertColumn(1,"1st Column");
But I dont see any columns ,apart from the listctrl box boundary...

Replace LBS_STANDARD by LVS_REPORT.

But the size is small.
How can I set the size of the ctrl in code..
Thanks all......

Check out the second parameter to Create().

You can adjust the CRect(..) in the Create function.
Or add WS_SIZEBOX style,then you can resize the control at runtime.
|

ok, to add columns to the list control, make sure that you create the control with the LVS_REPORT style.
then call CListCtrl::InsertColumn() to add a column and then CListCtrl::InsertItem() to add items. I saw a post that already indicated this.
Now to the problem of sizing the control to the size of your dialog:
In the dialog class, handle the WM_SIZE message, call GetClientRect() to get the current client rectangle of the dialog and then just call CListCtrl::MoveWindow() to size the list control to the size of the dialog.
HOpefully that explains it.
