litlmike Posted April 24, 2007 Share Posted April 24, 2007 Sorry if this has been asked 1,000 times already, but I cannot enter these symbols into the search feature on the forums and the Help File has very little to say about these operators. When would we use "==" versus "=" ? The help file seems to imply that the only difference between them is that "==" is case sensitive, is that entirely accurate? I bring this up because of a piece of code that I have been using in many of my scripts suddenly did not work in a new script, and after hours of debugging, I decided to try using "==" instead of "=" and the script ran perfectly. I will post the example at the bottom of thread, but the short of it is that I was looping and testing for a String value, and when a certain string appears then stop the loop. The below example works if the string value does/does not contain a space (" "), whereas previously when I used "=" it only worked as long as there was no space (" ") in the string. Feedback please? Thanks in Advance.

eynstyne Posted April 24, 2007 Share Posted April 24, 2007 == is to check whether something is true in C++, autoit doesn't really need this. A regular = will check and assign values = is to assign values to a variable F@m!ly Guy Fr33k! - Avatar speaks for itself__________________________________________________________________________________________ite quotes... - Is your refrigerator running?

EndFunc Posted April 24, 2007 Share Posted April 24, 2007 ThanksThen how do we account for the fact that using "==" fixed my script?Apparently it is needed for something because there are many examples in the helpfile that uses them and other scripts on this site. I don't exactly what the difference is either but would like to know also. EndFuncAutoIt is the shiznit. I love it. Link to comment Share on other sites More sharing options...
evilertoaster Posted April 24, 2007 Share Posted April 24, 2007 (edited) Unless used with a string = and == are the same. The help file explains this fine i think. 1==1 true "1"=="1" true 1=1 true "a"="A" true "a"=="A" false It is posible that there is some sort of auto-trim used with the == version but you could try and test somthing like Func Find_Table_in_Browser ($oIE, $iEnd) ;Get TableData i.e. like a List of Usernames $iCC = 0 Do $oTable = _IETableGetCollection ($oIE, $iCC) $aTableData = _IETableWriteToArray ($oTable) $iCC+=1 Until StringStripWS ($aTableData[0][0],8) = StringStripWS ($iEnd,8) Return $aTableData EndFunc;<==Find_Table_in_Browser() == is to check whether something is true in C++, autoit doesn't really need this.That's not entirely true as explained above.
