i am trying to import a fixed length text file into an access database (accdb). I already have the table created but it doesn't have to be that way. i am wondering if i know the field lengths, can i a use a SELECT INTO query to get the data into access. or do i need a schema file?

what do you think would be the best way to load a fixed length text file into ms access? this is how i would normally do it if it was comma delimitted:
sql.CommandText = "SELECT * INTO [tblMailList] FROM [Text;DATABASE=" & FilePath & ";HDR=NO].[" & FileName & "]"
sql.ExecuteNonQuery()
I've a text file which has some data written. Records have Starting character as "#2" and Ending character as "#3" in ASCII respectively and the file includes series of records, but not written as Line by Line. The difficulty I'm having is, to how to transfer those data's into a database. The File comes a 7mb file and looping character by character then noting down the Record Starting Character and Record ending Character, and finally substring them is not feasible as it take more time and makes the computer slower. I would like to know is there any easy way to transfer them?
View 3 RepliesI'm parsing fixed length file with .NET 3.5 and Regex. This file is from bank. In customer name sometimes there is one characters from this set &,(),[],',"". These are characters, so far I've encountered. There can be anything else. Because of this my regex is failing. My regex is [A-Za-z0-9s-.,'""""(){}[]]{35}. Is there any wild card I can use for special chars rather than specifying individually. I also tried . but didn't work.
View 2 Repliesso i have a file that i need to read in vb.net. Each line is 32 chars long and each line consists of multiple fields. Meaning from char 1 to 9 it idicates ID then char 10 indicates an identifier,11-14 indicates a value field. I've looked at Readblock and it's not the tool for the job. Is there a way to break up each line into its respective fields other than just reading the whole line and breaking it up as a string?
View 3 RepliesIf I dim an array to say, 5 elements, should it not fail if I go to add a 6th? I thought this used to require a redim. In .NET 2.0, I have a character array of length = 3. When I populate it from the db, one record had 4 characters in it and it successfully added all 4 characters to the array?

How do i Declare a string like this:
Dim strBuff As String * 256
In my application, a string generated its length can varying from 1 to 100 (not using random number algo). But I want if length is less than 7 than need to add integers 1,2,3.. untill its size reach to 7. I implements it using while loop as :
If generatedUserName.Length < 7 Then
Dim count As Int32 = 0
While generatedUserName.Length < 7

Got a dll from a supplier that I need to call. His declaration is Declaration with Microsoft Visual Basic: [code]Now, the Sting * 20 is clearly not VB.NET, and sure enough it crashes when run - "Attempt to read or write in protected memory" and that leads me to think that there is something with that string definition - or possibly the I_Ref definition which hasn't been defined as fixed length.I've tried <VBFixedString(20)> when defining O_Err, but I have a feeling that it might not be enough when the function declaration is like that (not specifically fixed length). I cannot figure out how to specify this correctly.As a small hmmmm, the above is pasted directly from the suppliers documentation, but that't will never work, as there is a "," missing after I_Range as long... Clearly not something he has pasted from a working program.

View 4 RepliesI am using VB .Net to access the eBay API and store all completed orders in a database. This database is then fed into a proprietary shipping system, which can not handle an order number larger than 20 characters. eBay returns an order number like so 230407279314-680141236013 which is too long. The order number is always 12 numbers a hyphen and 12 more numbers. What I need to do, is turn this (the result can be alpha numerical) into a shorter, unique order key to store in my database alongside the true orderId (so that this can be referenced by the shipping software instead of the actual order number). The reason for the 20 character limit is the barcode algorithm used. Is there any way to achieve this in VB .Net 2010? This number can be anything unique, so long as it does not exist already (even a good uniqueid function would work, but I would have to query the database to make sure it isn't taken)

VS2010 (SP1) / .NET 4 on Windows XP. The question is simple, the answer; not so much. When generating a salt, should the LENGTH of the salt be random, fixed or a random number within a (min/max) range? I am using RNGCryptoServiceProvider to generate the salt, just unsure of the length of the salt.

DoCmd.TransferText acExportFixed, "schema.ini", "table_ABC", "C: estingTestData.txt"
But I am getting error message: "Run time error-3625 The text file specification 'schema.ini' does not exist.You cannot import, export, or link using the specification."
Here schema.ini is at same location as of text file. i.e. "C: esting"
I tried with
DoCmd.TransferText acExportFixed, "C: estingschema.ini", "table_ABC", C: estingTestData.txt"
but no success.
For delimited format it is working fine
DoCmd.TransferText acExportDelim, "", "VDMMEMBS", "C: estingTestData.txt"

View 7 RepliesThis behavior occurs because the Subreport control has an implicit KeepTogether property. By design, the KeepTogether property tries to keep content of a subreport on one page. Because of this behavior, the report engine creates blank space on the main report if the subreport does not fit on the same page as the main report. Then, the report engine creates the subreport on a new page.

I would like to use CSV and all the other formats but some scientific programs written in FORTRAN may not support them. Anyway my file output here needs to be in this fixed width format because it will be used by proprietary software that I have no access to the source code.
