Programatically paste text into text box in another application
<p>I want to be able to paste the results from my application to another application.  Been Googling and all I can find is the <a href="https://msdn.microsoft.com/en-us/library/system.windows.input.applicationcommands.paste(v=vs.110).aspx" rel="nofollow">ApplicationCommands.Paste</a>.  That will paste it into my application not another application. </p>

<p>Background:  My application needs to interact with a very old application.  This application is not being developed and <strong>DOES NOT</strong> have any API calls. Meaning any answers like "Link your application via DLLs" will only be excepted if it also includes a time machine :P So the solution is to simple paste results from my app to the old application.</p>

<p>For workflow reasons the client wants my Application to disappear and automatically paste the results into an open text box in (if it fails then manually pasting the results in).</p>

<p>Hiding the window is simple, but how do I find current active application and then paste it in?  Is this even possible?  Also note this application is <strong>NOT</strong> .NET (VB 6 if I am correct).</p>
