I want to load a csv file (A comma delimited text file) into a datatable. I found the OdbcDataAdapter Class which looks perfect, but it says it is supported only in version 1.1 of the .NET Framework.
Is there a better way to import a csv file into a datatable? the first line has the column headers.
I am using Visual Studio 2008, using version 3.5 of the .NET framework
what would be the easiest way to open a comma delimited text file - each field is surrounded by quotes - and then analyze this file to find the record with the most fields being used? right now i bring the file into and access db then loop through each record to see if there is any data.

View 11 RepliesI want to add the contents of a comma delimited text file(PracInfo.txt) into a Dictionary on Form_Load. The contents of the file are as follows:
wlvc,coadmin
mrmd,thadmin
ccoa,oaadmin
bfhl,bfadmin
trty,tradmin
nppp,npadmin
For example, I want the wlvc to be the key and the coadmin to be the corresponding value. The code I have so far goes as follows:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim sr As New StreamReader("C:Programming filesPracInfo.txt")
Dim openWith As New Dictionary(Of String, String)
Do While sr.Peek <> -1
strHold = sr.ReadLine()
' here I would like to use the String.Split method on strHold and then put that into the Dictionary using Dictionary.Add(Key,Value) but not sure how to do this????
Loop
End Sub
End Class
I have a text file, with several lines of comma delimited data. The easy part is that each item fits into the same field, so I can use a 2 dimensional array. I would like to use .net classes to do this, not the old file handling functions I was used to.How can I take the text file and load the data in the text file into a 2 dimensional array.Here is example data in test.txt
1,1,1,2,2,2,1,1,1,3,3,3,4,4
2,3,4,5,1,1,1,2,3,4,5,1,1,1
2,3,4,5,6,1,1,1,1,2,2,3,3,4
So this would go into a (14,3) array.I would like to make sure, that the array is automatically sized to the size of the data also.

I am trying to import a TAB (NOt comma) delimited text file into a DataGridView. The following code works fine if I have a comma separated file. All I have to do is change the FMT to "Delimited".It just does not work with FMT=TabDelimited. All columns are read into single datatable column. The text file is ANSI text and I have double checked to make sure Tabs are tabs and not spaces, even exported a sample Tab Delimited file from Excel.Can this even be done using Text Driver? [code]
View 2 RepliesI recently asked a question about reading a file with Streamreader to variables arrays, but I made it more complicated than need be. Here is the simple version of what I am trying to do:
dim MyNumber(1) as String
strMyFile = 100,200 (I already have this)This is the result that I am trying to make happen:
MyNumber(0)=100
MyNumber(1) =200
I would also like the result to be MyNumber(0), MyNumber(1) as double, but I could do that in a later step. This is almost embarrassing to ask, because it is probably basic stuff.

View 8 RepliesI used to just code up a module that looked like this Ref to MS Access 11.0 Obj Lib was set
Dim myaccess as New Access.Application
myAccess = CreateObject("Access.Application")
myAccess.Visible = false
myAccess.OpenCurrentDatabase("c:\path\databaseName.mdb")
But now it seems that even with that ref included, none of these commands exist. From what I've been reading online, to do this via .net, you have to parse the file out and create a serious of SQL inserts. I'm assuming/hoping/praying that there is a more efficient way to do this...
What is the best method to parse through a Comma Delimited .dat file? I am using VS2002 and VB. My code will be looking for certain placeholders within the files and pulling the value from that element to populate a table in SQL2000.Here is a sample of one row that is in the database so far:17768 01 1770 003 2009-11-01 00:00:00 5065.14 NULL NULLEach spaced section is taken from a part of the .dat file, but being manually keyed in for now. My job is to automate the reading of the file, and writing it to the SQL database.Here is a sample of the flat file I am trying to parse:
0001,00003470,091411," "
0002,1000,0037707839,0000304220,0000282256,00000387
0003,1000,006795,0004,00000000,0000,00000000,0000,00000000,0000
There are about 12-13 'records' in each flat file, each row being a record as the sample shows.
I am looking for a different kind of solution here. I have a database in which I have around 14 tables. I have to write the output of 14 seperate queries to each of these tables in to a comma delimited file. I know how to write it using direct read , loop through and write to text. What I am looking for is a more configurable solution. I should be able to configure my application if a new table/query needs to be outputed. I should also be able to configure the delimiter to use.(I am Ok with C# or VB.NET )

I decided on a comma separated data file, saved as a text file. This is for data that will not change. After loading the data from the text file; then throughout the lifetime of the program the data can change. The data can then be saved back to a different binary file. The idea is to have a save state system going.Does anyone have a suggestion or is opposed to the idea. Is there a simpler way to organize something like this?

I want to list all the true results in a form which the user is then able to navigate through. What would be the best way to go about doing this?
Language: vb.net
File size: 1GB, and stuff.
Encoding of the text file: UTF8 (so each character is represented by different numbers of bytes).
Collation: UnicodeCI (when several characters are essentially the same, the most popular version will be the one unique.). I think I know how to handle t his one.
Because each character is represented by different numbers of bytes and each line has different numbers of characters, the number of bytes in each line also vary.
I suppose we have to compute hash for each line. We also need to store buffers location where the line each. Then we have to compare buffers. Then we will check whether the same line shows up or not.
