I have a database with a MEMO field. I need a code to find a certain word in the record and if found pull the data to the right of it. if not then do nothing and go to the next record.

Example.


field1                   field2
1                        this is a test and the word is great to be alive. How are you today
2                        today is friday and it is the week end



what I have here is two records.

I need it to look at the first record and find the word -----to
once found then copy the next 6 character would be:space be al
counting spaces this is how I get 6 characters

then go to the next record.
since-----to---- is not in the record do nothing. and so on until the records are all looked at.

Is this possible.

Platform = Visual Basic 6
                adodb = Microsoft Access database

Hi bear23

for each record
InfoAfterTo = Mid(DataBaseField, InStr(1, DataBaseField, "to") + 2, 6)
next

out of curiousity, because that might be a problem I face, what is the answer to that.

I tried what he was talking about and it seemed that if it seen any of the two character that it automatically pulled it. I even tried a if then statement and it still did it, meaning

keyword
to2

if  InStr(1, DataBaseField, "to") > 0 then
  InfoAfterTo = Mid(DataBaseField, InStr(1, DataBaseField, "to") + 2, 6)

else
   msgbox "No Match"
end if


the result was not the msgbox like it should have been, it did the infoafterto


is there a way to just lock the only work "to2"

not "to", to23344", "to2r", etc

Hi bear23,
InfoAfterTo = Mid(DataBaseField, InStr(1, DataBaseField, "to ") + 3, 6)
Note the space after the word to.
Otherwise, taking your initial example, the second row would not give a blank but capture "day is"

the problem I am having now that I am really playing with it is the fact that if anywhere in that record there is the identifier it is pulling it.

So example
concentrating on this if part
key word this time is:
to

I have the following statement

if  InStr(1, DataBaseField, "to") > 0 then
  msgbox "found"
else
   msgbox "No Match"
end if



record looks like this

I am going too
next record
I am going to the store

it is pulling msgbox found for both, it should only pull for the 2nd recordset
I am going to the store

why or how can I get this if then statement to work properly....

As Dabas pointed out if you are looking for the word "to" and you do not want to pick up every occurance of "to" and you actually want to pick up the word " to " add spaces and adjust the count.

So in this case you will pick up every occurance of "to " in "away we go into the wild blue yonder" using the code below you will get a message box of "found"

if  InStr(1, DataBaseField, "to ") > 0 then  ' "to " you are looking for this
  msgbox "found"
else
   msgbox "No Match"
end if

if  InStr(1, DataBaseField, " to ") > 0 then  ' " to " you are looking for this
  msgbox "found"
else
   msgbox "No Match"
