Selenium and wordpress: New post test

Question

I've been looking a bit at Selenium, and I'm beginning to like it, since I know some Java programming and find both Java and C# pretty straight-forward for simple things like this.

However, I'm struggling with a test that creates a new post in Wordpress, from the Dashboard page:

This is the Selenium code (in C#): (The Driver instance is, obviously, a driver class I've created - for starting the browser and connecting to the wordpress site.)

1: Driver.Instance.FindElement(By.Id("title)).SendKeys(title);
2: Thread.Sleep(1000);
3: 
4: Instance.SwitchTo().Frame("content_ifr");
5: Thread.Sleep(1000);
6: 
7: Driver.Instance.SwitchTo().ActiveElement().SendKeys("something");

Now, what happens is that the title is easily found (by ID, so I wouldn't expect problems there), and I can easily insert the title text (line 1).

But the inline frame for the post body is causing problems. When running the test, after the topic is filled in, the cursor changes to the body area (line 4) - as planned. However, nothing more happens. The SendKeys("string") method (ine 7) doesn't seem to work there.

Any ideas?

EDIT: Of course - an important piece of information is that the iframe in Wordpress simply loads a TinyMCE editor. So, in the page source, there's only a body tag with the javascript loading of the editor.

EDIT2: Of course, something suddenly changed. Without ANY change to the wordpress page, the "content_ifr" is now suddenly missing (?!!!!!?) The Selenium test fails with "unable to locate frame...", and it's also suddenly missing from the page source.

EDIT3: I also noticed something:

Driver.Instance.SwitchTo().Frame(iframe);
Driver.Instance.FindElement(By.Id("tinymce")).SendKeys("message body");

It's the SECOND line that makes the cursor switch to the mce field, not the line with the .SwitchTo(). However, I need the first line - the second line does nothing on its own. This is approaching something really stupid. I've been looking for a solution to this for a week - this doesn't exactly bode well for Selenium. The Selenium user group doesn't even want to answer when I ask them.

Also - if I skip the SendKeys() method in the second line, nothing happens. So, it seems that the two lines does ALLMOST what it should, right up to and including placing the cursor in the correct spot. But it never sends any text.

EDIT4 (last): After actually figuring out how to use IJavaScriptExecutor, it works using the solution(s) below.

Answer 1

Java method to handle TinyMCE editor would look like:

public void entersTopicOfBody(String textToBeTyped, WebDriver driver) {
        driver.switchTo().frame("content_ifr");
        WebElement body = driver.findElement(By.xpath("//body"));
        body.click();
        JavascriptExecutor executor = (JavascriptExecutor)driver;
        executor.executeScript("arguments[0].innerHTML = '"+ textToBeTyped+"'", body);
        driver.switchTo().defaultContent();
    }
