c#- SendKeys.Send("{tab}") to Internet explorer

HI,

I have created a simple winform application to launch the browser on a click of the button. The code is as follows:

        private void button1_Click(object sender, EventArgs e)
        {
           Process IEProc = new Process();
           IEProc.StartInfo.FileName = "iexplore.exe";
           IEProc.StartInfo.Arguments = "http://google.com";
           IEProc.Start();
           //IEProc.StandardInput.Write("Hello World");
           
           SendKeys.Send("{tab}");
        }

The purpose of putting the line "SendKeys.Send("{tab}");" is to navigate to the new field on google.com. However, the tabbing is happening on winform application. Can someone please let me know how the tab can be used on google.com.

Appreciate your help.

In order to implement the SendKeys function, you need to finde the internet explorer window that receives the user input and send an WM_KEY... message to it. I'm not sure if your approach is going to give you more problems than you think.

I would suggest to add a reference to the internet explorer interface through COM (automation). If you are not familiar with automation, take a look at this project:

When opening the iexplore you should just wait for a few moments before sending the TAB.
Why?

the iexplore is still opening when the TAB is send, and your winform is still in front. ;-)

waiting :
using System.Threading;


Thread.Sleep(10 * 1000); // 10 Seconds delay

try this

      IEProc.Start();
                  IEProc.WaitForInputIdle();

                  SendKeys.Send("{tab}");

you can get the process window handle, and the setfoucs to that window, before sending keys
check this, http://msdn.microsoft.com/en-us/library/system.diagnostics.process.mainwindowhandle.aspx


and pay attention to this note in the page
"If you have just started a process and want to use its main window handle, consider using the WaitForInputIdle method to allow the process to finish starting, ensuring that the main window handle has been created. Otherwise, an exception will be thrown."


good luck
