tooltips and memory leaks

[hartstein]

Hello, my company recently purchased the Active-x SDK. We originally prototyped it with the older 1.2 version.
I have observed 2 items with the new version

There appears to be a large memory leak (about 64K) each time the active-x control is used. The following vb6 program demonstrates the problem.

Private Sub Form_Load()
For i = 1 To 1000
Set ctl = Controls.Add("Foxit.FoxitReaderSDKctrl.2", "SDK", Form1)
ctl.Move 1, 1, Form1.Width, Form1.Height
ctl.OpenFile "c:\trash\t.pdf", ""
ctl.Visible = True
Controls.Remove ctl
Set ctl = Nothing
MsgBox "pause"
Next
End Sub

2) The tooltip text has appeared to disappear from the controls. I don't even see these strings in the resource file for the active-x control as all.

You should call function CloseFile after calling OpenFile. in this way ,you may reduce the size of memory leak.However there do exist the memory leak when ActiveX open a PDF document. About the tooltip text, it should be a bug of ActiveX 2.0.

This issue have been fixed in ActiveX 2.3
