The article contains exactly that info too, in addition to the system tray stuff. Skip the parts about the system tray and read how to make a single instance program.

When you run an instance of your exe, first you can check if another instance is running. If it is then make old instance visible and exit from the new instance.

Hi ,
My application basically contains a text box.

Once user presses a button, the data from the text box, should be added to an excel file.

Data should be appended..

Any solutions?

Erm, added where? Any cell number? Any work sheet?
Will you set a cell format?
Do you process how many active cells in a column there are, so your numnber can be added?

There are many questions for you to work out, before you dive in to the examples another poster just gave you.

Programming is all about being the whiny paranoid 6 year old saying "why?" and "what if?" all the time.

Unlike other data files where you open them, go to the end, and start writing, Excel files must be told where (i.e., what cell) to put the data. How are you doing this?

Hi,
i want to display a tooltip when the mouse pointer is over a specific part of window.
I am using the following code

if(IsResizable(ptHit))
			{
				//CRect boundingBox;
				//BOOL rval = TRUE;
				if (::IsWindow(mToolTip.GetSafeHwnd()))
				{
					mToolTip.UpdateTipText(_T("Resizing not possible"), this, 60000);
					mToolTip.Activate(TRUE);
				}
				else
				{
					BOOL rVal = TRUE;
					rVal = mToolTip.Create(this, TTS_ALWAYSTIP);
					if(rVal)
					{
	                    BOOL result = mToolTip.AddTool(this, _T("Resizing not possible"), CRect(100, 150, 200, 200), 60000);
						if(result)
						{
						  mToolTip.Activate(TRUE);
						}
					}
				}
			}

But the tooltip is not coming.

Thanks

Call method EnableToolTips().
Capture message TTN_NEEDTEXT.
Add ON_NOTIFY_EX( TTN_NEEDTEXT, 0, OnToolTipNotify) in the message map and implement method OnToolTipNotify.

I believe you can use GDI to render the text to a window or a memory context and then save its contents as an image.

These are the function for drawing using GDI Font and Text Functions[^].

You can try to look up for memory DC and how to save it to a image.
