IntStart1 variable returns 2 on 64bit and 0000029ae on 32 bit. please help.

Int32 intStart1 = strHtmlText.IndexOf("<TABLE class=");

String.IndexOf() is one of the most widely used functions in existence. I'd be simply astounded if it did not work.

The most likely explanation is that you have different values for strHtmlText. Inspect the values of that string and I'm sure you will see what is going on.
