    Re: How to check if a Word in a TextBox contains "+" Dosnt work For me

    InStr(TxtServiceName.Text, "+") <> 0 is correct. So is InStr(TxtServiceName.Text, "+") > 0

    If Not InStr(TxtServiceName.Text, "+") > 0 is to check for the absence of the + mark

    hey james i didnt quite understand what you said

    to use if not <> 0 or If Not InStr(TxtServiceName.Text, "+") > 0?

    Re: How to check if a Word in a TextBox contains "+" Dosnt work For me

    I wonder why InStr(TxtServiceName.Text, "+") <> 0 or InStr(TxtServiceName.Text, "+") > 0 or If Not InStr(TxtServiceName.Text, "+") > 0 when InStr(TxtServiceName.Text, "+") = 0 does the same thing directly?

    'Your code

    Basically you are telling it the opposite of what you want
    Code:
    If InStr(TxtServiceName.Text, "+") <> 0 Then
    Is the same as saying
    If + exists in the string then do this
    The value will be 0 if it does not exist and will be >0 if it does

    Code:
    If Not InStr(TxtServiceName.Text, "+") > 0 Then
    This is functional but not how I would do it

    I would use either
    Code:
    If Not InStr(TxtServiceName.Text, "+") Then
    or
    Code:
    If InStr(TxtServiceName.Text, "+")=0 Then
    I wonder why InStr(TxtServiceName.Text, "+") <> 0 or InStr(TxtServiceName.Text, "+") > 0 or If Not InStr(TxtServiceName.Text, "+") > 0 when InStr(TxtServiceName.Text, "+") = 0 does the same thing directly?
    They do not all do the same thing 1 and 2 will be true if the + exists in the string 3 and 4 will be false if it exists

    Re: How to check if a Word in a TextBox contains "+" Dosnt work For me

    Just to butt in and help simplify (although DM did a good job) furthur....
    the function Instr() returns the location (integer) where the search string (in your case "+") starts.
    If the string is not found, it returns zero (0).

    If you have a textbox with "HairDry + Manicure" you could did this:

    Code:
    if instr(text1.text,"+") = 0 then
          'code here would NOT run because instr() returned a 9 (9th character, including the space)
    else
          'code here WOULD run because 9 is not equal to 0
    end if
    OR

    Code:
    if NOT instr(text1.text,"+") then  'same as if instr(text1,text,"+") <> 0
          'run code here
    end if

    ...and, for example, if you are searching for a longer string, like "salsa"..
    In this example, you tell me what value would be returned to x:

    Dim x as integer
    x=instr("Where in the world is salsa sandiego?","salsa")

    Re: How to check if a Word in a TextBox contains "+" Dosnt work For me

    i see your point the problem is if i have 3 + then what?
    i mean like this
    Code:
    HairdDry + Manicure + HairCut
    i will get a error again and again
    the combobox can contain up to 3 names in 1 line

    Re: How to check if a Word in a TextBox contains "+" Dosnt work For me

    It returns the FIRST occurrence.
    Let me ask you...why are you now trying to use Instr()....the Split() command all have described to you is more applicable for your issue.

    Dim strParts() as String
    strParts = Split(combobox.text,"+")

    then, just check for ubound of strParts to find out how many treatments there are

    in this case, strParts(0) would equal HairDry
    strParts(1) would equal Manicure
    and strParts(2) would equal Haircut

    and ubound of strParts would be 2...so number of treatments would be 3 (0 plus 1 plus 2)

    YOu don't need instr() function at all here.

    beacuse i am making inserts if the combobox contains then 1 more name
    e.x
    if combobox has 1 name only with out this + then i use only 1 insert
    if combobox has 2 names [name1+name2] then i insert twice
    if combobox has 3 names[name1+name2+name3] then insert 3 times

    I showed you how to use a loop on the Ubound.
    You do not need to know how many are there.
    You do not need to use Instr() at all

    You need to follow instructions and ask questions if you do not understand

    Trust me I know what it is like to learn from self study. This is how I learned to do what I do and I did it when there was no internet to search and no one to ask questions. I literally learned by myself using just the book that came with the PC and a lot of trial and error or at least that is how I started. Later I did buy additional books and newer versions of languages came with online help and then eventually I got a job where there were other experienced programmers that I could talk to and of course the internet came to be a great resource.

    Learning is much easier if you pay close attention to examples and make sure you understand them before moving on. If someone gives you code that works but you do not understand and you just move on then when you face the same issue again you still will not know how to deal with it.

    Ask direct, detailed questions when you do not understand something. Give full detailed answers when someone asks you a question.

    What should I re-think? Let's take the string s="One+two". If InStr(s, "+")=0 then my text doesn't contain the "+" character. The question was simply "How to check if a Word in a TextBox contains "+". Sorry but I cannot get other meaning.

    Re: [RESOLVED] How to check if a Word in a TextBox contains "+" Dosnt work For me

    I wonder why
    InStr(TxtServiceName.Text, "+") <> 0 or
    InStr(TxtServiceName.Text, "+") > 0 or
    Not InStr(TxtServiceName.Text, "+") > 0 when
    InStr(TxtServiceName.Text, "+") = 0 does the same thing directly?

    Because you are making it sound like the last statement does the same thing as the first three statements and that is not correct. Actually, the first two are the same and the last two are the same

    Also, since the question was "How to check if a Word in a TextBox contains "+" then you should use <> 0 or > 0 to see if the word contains a + sign where you do just the opposite using = 0 otherwise OP's If statement will not be executed and OP wants to enter the If clause if it does where your InStr using = 0 will not enter the If clause.

    Actually in the OP it is entering the IF clause when the + exists where it then tells the user it does not exist

    In post 2 it enters when it does not exist

    Re: [RESOLVED] How to check if a Word in a TextBox contains "+" Dosnt work For me

    I went by the If statement; not what was in the clause although I would say OP wants to test if + does not exists and tell user

    That is true. But as Datamiser has noted, in the second post Salsa has hinted he actually wants to find out if that character is missing from that string
    i think i got it Code: If Not InStr(TxtServiceName.Text, "+") > 0 Then
    that is the same thing with If InStr(TxtServiceName.Text, "+") = 0 Then . I thought there is no confusion about it. On the other hand, it is sufficient to prove any value of a boolean variable even you are interested of other because of its dichotomy : False= nonTrue and vice versa. Finally, let's avoid a debate on such a trivial matter.

    James, you are a valuable poster of this forum. It is obvious it was just a little misunderstanding. Sorry for any inconvenience caused.
