<div>
FindWindow(0, &quot;WindowCaptionHere&quot;)<br />

</div>


<div>
I tried FindWindow(0,&quot;CAPTION&quot;) already. &nbsp;I think<br />
my problem is in the declaration of the function.<br />
Is there anything wrong with this?:::<br />
<br />
Declare Function FindWindow Lib &quot;User32&quot; Alias<br />
&quot;FindWindowA&quot; (ByVal lpClassName As String,<br />
ByVal lpCaption As String) As Long<br />
<br />
I tried without the alias and it wouldn't compile.<br />
Maybe the return type is wrong? &nbsp;I know the<br />
Function returns an hWnd but the compiler<br />
did not like that either.<br />
<br />
Thanks -- jr<br />

I know how to check the instance of the application that is running.<br />
But how can you check the instance of another application that<br />
might be running? &nbsp;I have tried to use the Windows API call to<br />
FindWindow(...,...) but I may be calling it wrong. &nbsp;If someone could<br />
point me in the right direction I would appreciate it.<br />

Instance of another application

Visual Basic is Microsoft’s event-driven programming language and integrated development environment (IDE) for its Component Object Model (COM) programming model. It is relatively easy to learn and use because of its graphical development features and BASIC heritage. It has been replaced with VB.NET, and is very similar to VBA (Visual Basic for Applications), the programming language for the Microsoft Office product line.
