Hi all. i am using this code to change color of listview item.
But unfortunetly it goes and changes color of all item instead
of only changing the color selected listview item. Could an expert
look at this and show me how i can only change color of selected
listview item instead of coloring all items in listview.Thanks

void CColor1Dlg::OnButton1() <br />
<br />
{<br />
<br />
HWND hPalWnd = ::FindWindow("my window class", NULL);<br />
<br />
        HWND spilterwindow = FindWindowEx(hPalWnd, 0, "WTL_SplitterWindow", 0);<br />
<br />
        spilterwindow = FindWindowEx(spilterwindow, 0, "WTL_SplitterWindow", 0);<br />
<br />
        HWND ATL = FindWindowEx(spilterwindow, 0, "WTL_SplitterWindow", 0);<br />
<br />
        HWND ATLWIN = FindWindowEx(ATL, 0, "atl:0053c8d0", 0);<br />
<br />
        HWND Dialog = FindWindowEx(ATLWIN, 0, "SysListView32", 0);<br />
<br />
        HWND Rich = FindWindowEx(Dialog, 0, "SysHeader32", 0);<br />
<br />
 <br />
<br />
            CButton *pButton1 = (CButton*)GetDlgItem(IDC_BUTTON1);<br />
<br />
            COLORREF GetBkColor(IDC_BUTTON1);<br />
<br />
            //COLORREF color = m_color.GetColor();<br />
<br />
COLORREF color = 33023;<br />
<br />
            TRACE("Color of the selected font = %8x\n", color);<br />
<br />
            //CButton *pButton = (CButton*)GetDlgItem(IDC_BUTTON2);<br />
<br />
            //pButton->SetWindowText("Shoot");<br />
<br />
        ::SendMessage(Dialog, LVM_SETTEXTCOLOR, 0, color);<br />
<br />

That code looks like an absolute nightmare...

I think that in order to do what you want you would need to have to do custom draw for your list view.

When it comes to doing anything out of the ordinary with a list control then Mike Dunn's article[^] is a must read.

Re: ComboBox DropDownList?

7-Jul-06 6:34

If not crashing is your metric by which you judge a piece of code... then there's nothing much I can say. Why do you have such a long chain of FindWindow() functions? And why aren't you using the RGB macro for generating the COLORREF. I'm sure not many people would know what RGB values make up 33023 offhand.

A (simple) limited user question

For a limited user on Windows XP, will regsvr32.exe be able to register a namespace extension? I tried and got error 0x80040201, but I'm not sure if this is an issue to do with the account being a limited user or not.

Any help would be greatly appreciated.

Thanks in advance!

Problem with NTGraph

Hello,
I have some problems with the PlotXY functions in the NTGraph activeX, Here is the article about this ActiveX:
http://www.codeproject.com/miscctrl/ntgraph_activex.asp[^]
I'll upload for you the picture of the problem here:
http://img433.imageshack.us/img433/4972/untitled2ee.jpg[^]
the function I wrote there the code is: BOOL CGraphsXYAxisDlg::OnInitDialog()(This is the function in the general Dialog)
I sure the problem is there because when I earase the line it works fine.
I tried a few combinations of the point(x,y) but it doesn't work and the errer occurs.
Do you know how can I fix it?
Thank you all for your great help!

Incidentally the correct place to post these questions would actually be at the relevant article[^] itself.

The error message says Element not found. Do you actually have 3 elements for your graph? (ie. did you add 2 extra elements as the 1st was created automatically)

How can I draw a line with this ActiveX.
I tried to use the functions:
OLE_COLOR ElementLineColor
OLE_COLOR ElementPointColor
LineType ElementLinetype
but it doesn't draw..
Do you have any ideas how can I draw a line between all the points?

Provide some source code of what you are doing. I don't see what is so difficult.

Semion_N8-Jul-06 5:16

I just want to know how to join/connect the points with a line.
I'll upload an image for you to understand well-here:

I know what you want to do. I want to know what steps you have taken to attempt to achieve this and your existing code because it looks to me like the SetElementXXX functions have everything you need.

Semion_N8-Jul-06 5:42

8-Jul-06 5:42

I haven't tried to add the line because I totaly dont know how. I just know how to add points to the board, if you want the code of adding the points: take:

<br />
//this functions is from the BN_CLICKED event(its a button to plot point)<br />
void CGraphsXYAxisDlg::OnBnClickedButton2()<br />
{<br />
	//UpdateData(TRUE);<br />
	m_Graph.AddElement();<br />
	m_Graph.SetElementWidth(10);<br />
	m_Graph.PlotXY(X,m_Y,X);<br />
	X++;// X is public variable and I use it to set the X and to set the X and the element number.<br />
                UpdateData(FALSE);<br />
<br />
}<br />

Thank you!
