I have a dialog User Interface that has two Sliders and several other buttons. I am looking for a way to find out when a particular slider is selected and/or active. Active meaning the mouse movement results in slider movement. Any help would be great.

The parent will receive WM_HSCROLL/WM_HSCROLL notification messages on slider movement.
To look for it being selected, maybe respond to WM_SETFOCUS in the control(?)
Check out the "Trackbar Notification Messages" section here: Trackbar Controls[^]

I am not sure how to obtain, set or get the WM_SETFOCUS messages from Dialog item.

You stated you wanted to know if the control was "selected" so hopefully that means you need to
know when it gets focus (like when you tab to a control in a dialog).
If so, you could...
In MFC, derive a class from CSliderCtrl and add a handler for WM_SETFOCUS.
For non-MFC, subclass the trackbar control and look for the WM_SETFOCUS message there.

Why don't you cast the pScrollBar parameter pass with the OnHScroll to CSliderctrl..
void OnHScroll(UINT nSBCode, UINT nPos, CScrollBar *pScrollBar)
{
// TODO: Add your message handler code here and/or call default
int nControl=pScrollBar->GetDlgCtrlID();
CSliderCtrl* pControl= static_cast<csliderctrl*>(GetDlgItem(nControl));
switch (nControl)
{
case IDC_SLD_CTRL:
{
}.
.

Hello,
I am planning to write a program that will do string find and replace for any text file. Can anyone one give me any suggestion what is the best way to do it, or is there any existing library already provide this feature? I can write my own but it may not be efficient enough. Any suggestion? Thanks!

Hello,
In my program I have a variable which stores hwnd of a window. In order to close that window I use Postmessage and WM_Close but there is a problem. When the program is launched second time hwnd of the window that was closed is the same and the window is not shown at all. Consequently IsWindowVisible returns false for that window. I decided to use Showwindow to make that window visible but it doesn't work. After executing Showwindow(hwnd,1) Iswindowvisible returns true but that window is still not shown. So is there a way to make invisible window visible or to close it in such a way that when it is initialized second time it is visible. Thanks

There's no guarantee the HWND will be the same the next time you run an application, so comparing
the HWND to the one in a previous instance is irrelevant.
If you meant "When the window is launched second time ..." then -
If the default window proc for the window handled the WM_CLOSE message then DestroyWindow() has
been called on the HWND so it's no longer valid. In that case, you need to create a new window,
which possibly will have a different HWND.
It's up to you to keep track of the HWND

Yes I know but in my case it is the same.

No I didn't

CreateWindow(Ex) is being called the second time and succeeding?
"Go that way, really fast. If something gets in your way, turn."

wait what about:

No, it isn't. Actually, it is a .NET application using dllimport to access winapi functions. I have a notifyicon and in the balloontipshown eventhanler I use findwindow to find hwnd of the balloon tip. Every time I launch the application, the hwnd of balloon tip is the same. Of cource it changes after restarting windows or explorer.exe

Wow...I was sure thinking in a different direction 
The second time your app runs, try calling ::IsWindow(hwnd) on the HWND.
Is it valid or have you destoryed another processes window?

I'll do it this evening.
I have noticed that when I use showwindow to make the balloon tip visible, it is shown but only part of its border and very unclearly. So I suspect that when I close it by sending wm_close button I destroy all its properties including styles and all the stuff so maybe I need to set style for the balloon tip during runtime?

Yes, posting a WM_CLOSE message to a window, by default, causes the window to be destroyed.
Can't you just use ShowWindow(SW_HIDE) instead of destroying the window?

I thought about it but it leaves some trace like the one when you close the balloon tip and a little part of it is still visible. Is it possible to set cursor position at the x button of balloon tip and click it programmatically?
