single quote vs double quote in parameters??

11 posts in this topic

is there a difference between this:

$result = StringInStr($sHTML, 'style="position:absolute')

and this:

$result = StringInStr($sHTML, "style="position:absolute")

does the single quote make a difference as opposed to the double quotes??

Look at the syntax highlighting in Scite, and even in your post for instance, you can see that everything after style=" is considered to be separate from the string "style=" in the second example. If you need to use double quotes in a string, you have 2 options. 1 is to use single quotes around the whole string, 2 is to double up the quotes inside the string.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

its strange how someone with 120+ posts did not use forum search function

have fun testing

MsgBox(0,'1 -single_x1',"a'a")
MsgBox(0,'2 -single_x1','a''a')
MsgBox(0,'3 -single_x2','a"a')
MsgBox(0,'4 -single_x2',"a""a")
MsgBox(0,'5 -double_x1',"a''a")
MsgBox(0,'6 -double_x2','a""a')
MsgBox(0,'7 -single_x1','a'&"'"&'a')
MsgBox(0,'8 -single_x1','a'&''''&'a')
MsgBox(0,'9 -single_x2',"a"&'"'&"a")
MsgBox(0,'10-single_x2',"a"&""""&"a")
MsgBox(0,'11-double_x1','a'&''''''&'a')
MsgBox(0,'12-double_x2',"a"&""""""&"a")

Look below to where I highlighted what I stated previously. Double up INSIDE the string, not the whole string

StringInStr($sHTML, "style=""position:absolute")

Thanks for the example. It would be nice if next time there was a little less attitude tho. Atleast you were helpful.

These days I've switched to using single quotes in my code (looks clean in my opinion) than the standard double and it causes less hassle when having to provide quotes around something e.g. a filepath.

Before:

MsgBox(4096, "", "Some text in a ""MessageBox!""")

After:

MsgBox(4096, '', 'Some text in a "MessageBox!"')

True. Though my use of SQLite is probably less than what yours has been.
