I am using this code to change text color of listview selected item. But it never works.Could an expert look at it and tell me what i am doing wrong. The hwnd is corect since the line :
[code=vb]lItemPos = 0& ' first item
SendMessage hwnd, LVM_SETITEMSTATE, lItemPos, ByVal lxprocLVITEM[/code]
is working perfectly and is selecing the zero position item for me and highlighting it corectly.
Some people suggest i need to send a refresh using LVM_REDRAWITEMS to listview after setting a color for it. But i do not know how to use LVM_REDRAWITEMS. I be happy if an expert help me fix there problems.Thanks
not working call to LVM_SETITEMSTATE
Private Const LVM_SETTEXTBKCOLOR = (LVM_FIRST + 38) <br />
<br />
lItemPos = 0& ' first item<br />
SendMessage hwnd, LVM_SETITEMSTATE, lItemPos, ByVal lxprocLVITEM<br />
<br />
'SendMessage hwnd, LVM_SETTEXTBKCOLOR, 0, hexdec(16711935)<br />
'SendMessage hwnd, LVM_SETTEXTBKCOLOR, 0, 16711935<br />
'SendMessage hwnd, LVM_SETTEXTBKCOLOR, 0&, 0&<br />
<br />
<br />
<br />
SendMessage hwnd, LVM_SETTEXTBKCOLOR, 0, 16711935<br />
<br />

Are you doing this so you can change that appearance of a listview in your own app or another one?? If your doing this in your own ass, you're going about it the hard way. search the articles for "ownerdraw listview" and you'll come up with a few good examples.

I am doing this for external listview . I mean in another application that i do not have its source code!

OK. Well, the docs on the LVM_REDRAWITEMS[^] message are pretty straight forward. You already have the mechanism to send the message. All you need to do is supply the listviews first and last item numbers that need to be redrawn.
Now, you have a second, more serious problem, that you can't get around. If this was your own ListView and your were ownerdrawing it, your code would have to be written to specifically handle this message. I have yet to see an ownerdrawn ListView that does this. If the app your trying to control like this ownerdraws its ListView control, you're S.O.L, and none of this will ever matter.

could u tell me what should i put for the parameters in my case :
SendMessage(
(HWND) hWndControl,
(UINT) LVM_SETTEXTCOLOR,
(WPARAM) wParam,
(LPARAM) lParam
<br />
);
I have no idea what should put and replace what ?

Don't tell me you copy-paste-and-prayed the code you posted??
LVM_REDRAWITEMS is (LVM_FIRST + 21)
The wParam value should be the index number of the first ListView item that needs to be redrawn. The lParam value should be the index of the last item.
So, you're code would be something like:
Private Const LVM_REDRAWITEMS = (LVM_FIRST + 21)
.
.
.
SendMessage hwnd, LVM_REDRAWITEMS, firstItemIndex, lastItemIndex

It does not work !!!
SendMessage hwnd, LVM_REDRAWITEMS, 0, 12
|
|
|

Then it's entirely possible that the ListView you're trying to control is ownerdrawn by the other application. In which case, there's nothing you can do to get the effect you want. This is because the ownerdraw code will always paint the items exactly how its written to, ignoring the attributes that your injecting into the items list.

Then I'm failing to see what your problem is or what your intended effect is...
You're original post said the code is working, but in the next sentence, says that people are suggesting sending other messages. What's broken??
Are you saying that you have C++ code that is working, but when you try to convert it to VB.NET it isn't??

i mean i have visual c++ version of code and it is working but i try to convert it to visual basic 6 and it is not working. they suggest the redraw methond and non works!! It was mentiioned that some other application is sending redraw so that is why it is not working the give code and i said no because the visual c++ is working corectly
Now all i want to make this work . It is visual basic 6 code!

We'll have to see the C++ code you're using and the VB6 code came up with from it. There's obviously something missing...

Here is the visual c++ version :
void CColor1Dlg::OnButton1() <br />
{<br />
HWND hPalWnd = ::FindWindow("my window class", NULL);<br />
HWND spilterwindow = FindWindowEx(hPalWnd, 0, "WTL_SplitterWindow", 0);<br />
spilterwindow = FindWindowEx(spilterwindow, 0, "WTL_SplitterWindow", 0);<br />
HWND ATL = FindWindowEx(spilterwindow, 0, "WTL_SplitterWindow", 0);<br />
HWND ATLWIN = FindWindowEx(ATL, 0, "atl:0053c8d0", 0);<br />
HWND Dialog = FindWindowEx(ATLWIN, 0, "SysListView32", 0);<br />
HWND Rich = FindWindowEx(Dialog, 0, "SysHeader32", 0);<br />
<br />
<br />
<br />
CButton *pButton1 = (CButton*)GetDlgItem(IDC_BUTTON1);<br />
COLORREF GetBkColor(IDC_BUTTON1);<br />
<br />
COLORREF color = 33023;<br />
TRACE("Color of the selected font = %8x\n", color);<br />
<br />
::SendMessage(Dialog, LVM_SETTEXTCOLOR, 0, color);<br />
<br />
}

Hi

If any one not understood my question
My Question is Incase if i have two hashTables and does not contain same key values , so there is no link between the two tables right.
Now i want to loop thru both the hashtables at a time
like one value from 1st hashtable and one value from the 2nd hashtable
then move next ....so on
Can i use for i as integer=0 to ht.count or something like that ??
blue

You have to call each htable's GetEnumerator() to get the enumerator and then walk through the collection. This article contains some code snippets: link.
Best,

The items in a hash table are not stored in a way that you can retrieve them in the order that you stored them. If there is no way of associating the items in the two lists from the data in the items themselves, you can't list them correctly.
Unless, of course, you don't care at all in what order the items comes from the lists.

Hi all:
I need to get mouse position information which is easy enough to do with the form's mouseMove event. I've noticed, though when the mouse passes through a control, the flow of x,y coordinates stops.
How do I get a continous flow of information? I suppose I could add a mouseMove event to each control, but that seems like a kludgy way of doing things.
Thanks,
Norm

You could add a handler in your form for the controls when you add them. Something like this:
Public Sub AddControl(ByVal Control as UserControl)
AddHandler Control.MouseMove, AddressOf HandleMouseMove
Me.Controls.Add(Control)
End Sub
Private Sub HandleMouseMove(ByVal sender As Object, ByVal e As MouseEventArgs)
'handle your mouse move stuff
End Sub
Hope this helps. As well, don't forget that if you use AddHandler to add an event handler, always have a RemoveHandler when you close your form, otherwise your application will have a memory leak.
Public Sub RemoveAllControlHandlers()
For Each Control as Control In Me.Controls
RemoveHandler Control.MouseMove, AddresOf HandleMouseMove
Next
End Sub
