Dorababu... how do I find the appropriate window handle? For example, I would want the log on window associated with the QuickBooks process.
</div>


<div>
Can you show some code how you are opening up the quick books thing
</div>


<div>
Yes...<br>System.Diagnostics.Process.Start("\"C:\\Program Files (x86)\\Inuit\\QuickBooks 2019\\QBW32.exe\"");
</div>


<div>
You want the focus back to the form from you are opening?
</div>


<div>
I want to make sure that I have the log on form has focus before I send the username and password. <br><br>I also want to do this periodically to make sure everything is working as planned.<br><br>
</div>


<div>
Can you try this as per required<br><pre><code class="code-10 nolinks" id="code-20-43327085-1"><span>DllImport("user32.dll")]</span>
<span>[return: MarshalAs(UnmanagedType.Bool)]</span>
<span>static extern bool SetForegroundWindow(IntPtr hWnd);</span>
<span></span>
<span>private void button1_Click(object sender, EventArgs e)</span>
<span>{</span>
<span>&nbsp;&nbsp; Process process = new Process();</span>
<span> &nbsp; process.StartInfo.FileName = @"D:\LoadTest\WriteLines1.txt";</span>
<span> &nbsp; process.Start();</span>
<span></span>
<span> &nbsp; process.WaitForInputIdle();</span>
<span></span>
<span>   SetForegroundWindow(this.Handle);</span>
<span>}</span>
</code></pre>
</div>


<div>
The log on form was just an example... let's say I log in and want to create an account. I push the sendkeys to do that and now I want to make sure &nbsp;that I am at the "create account" screen before I start sending for keys...

@jonathan... although this looks pretty cool I don't see much documentation.<br>The issue seems to be that sometimes the main program opened loses focus... so I want to set focus back to the main program... particularly the username text box.<br>The help.chm file shows lots of things in the index, but no pages pop up on the right side.

@Jonathan &nbsp;I implemented this solution and it appears to be working. Thank you!

I have written a "sendKeys" app that works well.
I'd like to further its reliability by being able to
set focus
on expected windows/forms.
The desktop application is written in C#.
So, for example, if the app is ready to supply a username and password to a form who's title bar reads
Intuit - Quickbooks Log On
, how do I make sure that that window/form has the focus?
Thank you...

c#.NET set focus on a window?

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).
