POGet focus on third party application and return
text
Body
copied!<p>I'm writing in C#.</p> <p>I have a process that lunches a third party application embedded within my program. I also have a RichTextBox in which I write text and then it shown in the embedded application real time. Everything works but I need to move the mouse, for the application will get focus and then refresh and show me the changes.</p> <p>This is the process: </p> <pre><code>private void button2_Click(object sender, EventArgs e) { System.IO.File.WriteAllText(@"ForParsing.txt", textBox1.Text); pdf.StartInfo.FileName = @"yap.exe"; pdf.StartInfo.Arguments = "ForParsing.dvi"; pdf.Start(); pdf.WaitForInputIdle(-1); SetParent(pdf.MainWindowHandle, this.splitContainer2.Panel1.Handle); SetWindowPos(pdf.MainWindowHandle, HWND_TOP, this.splitContainer2.Panel1.ClientRectangle.Left, this.splitContainer2.Panel1.ClientRectangle.Top, this.splitContainer2.Panel1.ClientRectangle.Width, this.splitContainer2.Panel1.ClientRectangle.Height, SWP_NOACTIVATE | SWP_SHOWWINDOW); } </code></pre> <p>I have a key press handler below for the TextBox. When key is pressed, I Focus on a third party application that is embedded in my program.</p> <pre><code>private void richTextBox1_TextChanged(object sender, EventArgs e) { System.IO.File.WriteAllText(@"ForParsing.txt", textBox1.Text); //Focus on third party application SetForegroundWindow(pdf.MainWindowHandle); } </code></pre> <p>So far so good. Now the problem: I want the focus instantly returned to the same place the courser was in the TextBox. I want to be able to keep on writing in the TextBox like nothing happened except the real time refreshing of the embedded application.</p> <p>In simple words, I need the third party application to refresh (gain focus) instantly and me be able to type without interference, at the current position I stopped, in the TextBox. </p> <p>Is it possible to so? Is there a better, more simple solution for this? would happily listen to any advice. </p> <p>As I'm not allowed to answer my own questions, I will write it here:</p> <p>I've found a solution tinkering with people's problems</p> <p>Here is what I've done:</p> <p>private void richTextBox1_TextChanged(object sender, EventArgs e) { System.IO.File.WriteAllText(@"ForParsing.txt", textBox1.Text);</p> <pre><code> //Focus on third party application SetForegroundWindow(pdf.MainWindowHandle); //Restore focus pdf.WaitForInputIdle(); SetForegroundWindow(this.Handle); this.Focus(); </code></pre> <p>}</p> <p>Thanks for the help everyone</p>
