Advice Sought - Using A DB To Store File Contents Vs Reading Text File Straight Into VB
I have an approx 300 line comma separated and hierachically arranged text file and am currently duplicating the comma separated bits into various Access database tables and reading it into VB from there. I'm not too keen on duplicating the info and am looking for a neat way to either parse the original file straight into my VB GUI's memory space or some how tokenise the file. I know that this can be done with lex/yacc and c++ and am wondering what the best VB route to go down would be.
Any advice would be gratefully received!!!

Is It Possible To Store Command Names In A Text File?
This is what I am attempting to do. I am building a wizard with only one form and all the text, help and control names stored in a ini file. As the user makes selection the form gets updated by reading the next section in the ini of that sequence.
So lets say my ini file looks like this
Can I read those from the file and then have them execute a .show in the code. Basically is there a way to have a variable take the place of a command name, so I can reference txtdesc.text as strFiledata & .text?
Is this possible?
Array, And Text File Read To Store String, Help Please
I'm having a hard time getting the arrays and infinite looping to work correctly.
When I press the "ok" button, I want my program to open and read a text file, and read each line of text and store it into a string, I then want the string broken up, and if a textbox = one of the broken up strings, I want it to go to the next forum and display it. At the same time, I want to be able to edit the .txt file and add more entries to each line. Meaning... I can add any number of entries I want too.
So here is what I have below...
Dim READER As String
Open "T:StaffordProjectProgrammingids.txt" For Input As #1
Line Input #1, READER
Display1.Caption = READER
What this does is open the file and reads line #1, then closes and displays it in the display1.caption, I want it to read X number of lines = infinite, and I want it to split the string, by "-" but when I split, I seem to have a problem with that... it doesn't need to display the strings, it needs to keep a record of them so when the numbers are punched in and equal a string, it will go to the next form.
Here's what the text file looks like inside... 6 numbers and a name.
So if I press 3,2,5,4,3,5, and then hit "ok" it goes to the next form with 325435, Mark Lane as logged in.
Binary File Access: String Doesn't Store Some Characters
Sorry for the cryptic subject.
I was trying to read a file in binary mode. Here's the code.
dim Data as String, Chas as String*1
Pos = 1
open "c:1.txt" For Binary As #1
While Not EOF(1)
Get #1, Pos, Char
Data = Data & Char
'txtOld = txtOld & Char
Pos = Pos + 1
txtOld = Data
The problem is that if the file contains non - printable characters, then the code doesn't read them. If I use the commented portions instead, there is no problem, but that would slow down the I/O.
Why is this happening? What is the solution?
Locating Records In Access Database Thru VB Code
I am using VB6.0. I have connected my MS Access 2000 database using ADODC. How can I search and display all records matching a criterion. For example, to display all records with surname beginning with 'MO' in the SurNamefield of the database.

ADO Code For Adding, Editing && Deleting Records In Access 2000
I would like to get some basic ADO "Code" for Adding, Editing & Deleting records.
I have an Access 2000 database with multiple fields, "FirstName", "LastName", "City", "Country", etc. and have the ability to search the records with option buttons to determine the field to select for the search, but I don't know how I can add, or delete these records using code. If you need to see the existing code that I have for further information to answer the question, just let me know and I'll put it up.
On the other hand, is it better to use the ADODC control.
I tried to use the form wizard to make the form and then add a search feature to it, but I just can't get it to work together.
Independently, the search works just fine, but not on the same form with the Add, Edit, Delete features.
Any help would be greatly appreciated & thanx in advance.

How Many Records In A Text File
I have created a file with this statment and a user defined type (udtRecord).
Open strSaveFile For Random As #1 Len = Len(udtRecord).
I can store as many records into the file as I want without problems.
What I am unsure of is how to retrieve this data, where to store the data in the program (string array?) and how many records are stored in the text file.
Here is the code
Open sSaveFile For Random As #2 Len = Len(udtRecord)
Get #2, ["Unknown if I should place anything here"], iRecord
.FamilyName = DecryptData(.FamilyName, "Mz92#")
.Address = DecryptData(.Address, "Mz92#")
.City = DecryptData(.City, "Mz92#")
.State = DecryptData(.State, "Mz92#")
.PostalCode = DecryptData(.PostalCode, "Mz92#")
.DonDate = DecryptData(.DonDate, "Mz92#")
.CkNum = DecryptData(.CkNum, "Mz92#")
.PaymentMethod = DecryptData(.PaymentMethod, "Mz92#")
.TotalAmount = DecryptData(.TotalAmount, "Mz92#")
.AccountName = DecryptData(.AccountName, "Mz92#")
.Notes = DecryptData(.Notes, "Mz92#")
So I need to loop through the textfile and store the data in udtRecord somehow. Thanks for the help

Counting Records On Text File
I've got sort of a problem. The detail is long because I don't know how else to explain it...
A procedure exports an excel file to a tab text file. It then executes the CountRecords function (see below) to verify that the number of records on the text file match those from the original excel file. It seems to be doing it accurately but with one problem. In Excel the original file remains open in case the user needs to refer back to it. While executing the CountRecords code, I'm not entirely sure on why or what it is doing but the line "Cells(l, 5).Formula = .ReadLine" changes the actual original excel file (eventhough upon exporting it, excel changes the filename with the .txt extension, it changes at least what I'm viewing) so that Cells in Column 5 are equal to whatever is in .Readline (which is quite a long string). I do realize that the exported text file is not harmed, however I am weary of any changes that are made to what I see as the original Excel file.
What I'm hoping is that I can change that line to do the same thing for code progression but not affect the view of that text file in Excel. Deleting that line, causes an infinite loop.
Here's my code:
Public Function CountRecords(filepath)
Dim fs As Scripting.FileSystemObject, f As Scripting.TextStream
Dim l As Long
Set fs = New FileSystemObject
Set f = fs.OpenTextFile(filepath, ForReading, False)
l = 0
While Not .AtEndOfStream
l = l + 1
Cells(l, 5).Formula = .ReadLine
Set f = Nothing
Set fs = Nothing
CountRecords = l
Importing Different Records In Same Text File
Ok I have multiple text files and in each file there are different records that need to go into seperate tables. I have no Idea where to start I know its easy and I have some code written up but I am making this more complicated than it needs to be. each record starts with 3 characters such as IDN, CHG, ARR etc... and each of these characters need to be in there own table. The problem is that they are all clumped in the same text file... does anyone know where I can get code that will help me out a bit?

Deleting Random Access File Records
For years I have always thought there must be a better way when it comes time to delete records from a random access file that contains a mixed bag of data types. My usual procedure has been to first earmark the records that need to be deleted using a byte or Boolean array. Then I open a temp file and with a series of Get and Put statements, write the new records to the temp file, then delete the original and rename the temp file back to the orginal, now repacked.
On occasion, I read the whole file into several arrays, one for each data type, kill the original file, hold my breath, and then reopen and write the file back out using the arrays. That, of course, is a bit precarious and seems more of a memory hog. Any suggestions?
Deleting Records From A Random Access File
I have read on how to open, read or write and close using random access. Now can someone tell me on how to delete?
Ok basically I am doing a small Address book application and I'm storing the info into a text file. I have 5 command buttons (New, Next, Previous, Delete, Search and Exit) which gives the user control over thier address book. But I am having trouble deleting a record.
Since there is no 'delete' command, I basically stored empty variables into the record but when looping through the entire file for all the records, the empty ones shows up.
I was thinking maybe of storing the 'deleted' records into an array when the program starts and whenever the user moves forward and backward through the records, it checks to see if the record is deleted by checking it against the records in the array. If it is, it skips it.
Is this a good way of doing this, or does anyone have a better way of going about this?
And I have to use the text file for the storage.
How To Count Records/Rows In A Text File
I want to use a For Next loop to process the info in a text file. To do that I think I need an upper limit number. So I want to count the number of records in the file. How can I do that. I thought something like the below would work but it didn't.
Dim NumRecords As Integer
Private Sub cmdCountRecords_Click()
If Not EOF(1) Then
NumRecords = NumRecords + 1
picOutput.Print "Number of Records = "; NumRecords
Private Sub Form_Load()
If Right(App.Path, 1) <> "" Then
Open App.Path & "ModifiedMIM.txt" For Input As #1
Open App.Path & "ModifiedMIM.txt" For Input As #1
