I have a load of text files that contains one record per file . Each field data is separated by as follows !!:number:Field data!!. I need to be able to read each line (record), set a variable to each field, and then insert a new reocrd into an access database using the variables. How can I set my variables to their corresponding values from the text by searhing for !!:number:Field data!! ?? I appreciate any help! I know that it has to do with parsing the text files, but I just amn't sure how to go about doing it!!!
Thanks a million,
JK

This is a rough stab in the dark, as I haven't thought about the actual parsing of the data yet, but would it not be worth trying the import text wizard in Access? You can set the field delimiters (to !), and if multiple delimiters occur (i.e. !!), this can be take into consideration. The only problem I see with this is that I cannot see any sign of a record separator (e.g. an ENTER key) - it looks like it could be the colon...
Post back if it doesn't work - we'll have to parse it then (nasty...)

Thanks a million for the reply. The problem that I have is that there are about 10,000 of these files that are all stored in different folders and more files come in on a daily basis. So what I need to do is be able to update the database as well as developing a user web interface to the database.
Your help is greatly appreciated

If you are using VB6, you can use the SPLIT function to separate your fields. It will allow you to use a delimiter of "!!" to place each field into a separate element in an array.
Example:
Code:
Private Sub Command1_Click()
Dim strTest As String
Dim strResult As String
Dim strArray() As String
Dim x As Integer
strTest = "this!!is!!a!!test!!string."
strArray = Split(strTest, "!!")
For x = 0 To UBound(strArray)
strResult = strResult & strArray(x) & vbCrLf
Next x
MsgBox strResult
End Sub

Hi ender_pete
Thanks. In response to your questions, all the files follow the exact same format with the same deliminaters. They are generated by a system which sends them to me in this exact format.
Thanks again

jbart hit exactly what i was gonna say.
like his code shows use the split function on a string to split the seperate fields up.
but first you have to load the string.
if your files are over 2 billion characters you won't be able to do this beacause a string only holds about
2 billion characters, any more and you'll get an overflow error. here is the way i access files, i use the FileSystemObject and the Textstream object.
first create the FileSystemObject then the textstream object
fso opens the files as text stream so it would go like this
Code:
Dim fsoDataFile As New FileSystemObject
Dim objText As TextStream
Dim strData as String
Set objText = fsoDataFile.OpenTextFile("C:\temp\whatever.txt", ForReading)
strData = objText.ReadAll
then all you have to do is use the split function load it into an array, then the fields will be in order and its just a matter of looping through the array and populating the database.. now in the code above the file name where i put C:\temp\whatever.txt does not have to be static like that you can use a string with the filename in it that way you can just make this a function an pass the filename to it. then you just have to be able to search the hard drive to find the files..
hope this helps.
