Hi All,

Q1: the page total char is 2336 ( count by MS Word ), but IndexOf
return 16xxx, it is larger than total lenght, interesting thing is
when I use substring to get the string I want, it still works.

Q2. Due 'at' return very large value, how to deal with overflow
issue ....


/* CODE BEGIN */
int at =0;

private void webBrowser1_DocumentCompleted(object sender,
WebBrowserDocumentCompletedEventArgs e)
{

while ( at !=-1)
{
at = webBrowser1.DocumentText.IndexOf("something somewhere",start);
start=at+1;
}
}
/*CODE END */

Best regards,
Boki.

Not sure what the question is here. But since you're dealing with a
WebBrowser control, I guess the string contains HTML tags that you
don't see when viewing the document in Word.

You'll reach the size limit of a string object before int would
overflow, so don't worry about that.
