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 7 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 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.

View 9 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.
I am a beginner at this and I am taking classes, however I am having trouble deleting a line from a Comma Delimited .txt file.[code]...
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 )

View 3 RepliesWhen I use to do some Delphi programming you were able to define variable as a target for a comma delimited file and then under that give variable names for each field to fall into. I forget the syntax now but it looked something like this...

There is way to input comma delimited files:
Using MyReader As New Microsoft.VisualBasic.FileIO.TextFieldParser(currentfile)
MyReader.TextFieldType = FileIO.FieldType.Delimited
MyReader.SetDelimiters(",")
Is there an equivalent way to output a comma delimited file. The approach I used in earlier versions of Visual Basic does not work in .NET.
I have been using:
Printline(1, val1, val2, val3)
In .NET that is not comma delimiting
For now I am hardcoding ... & ", " & ... between variables.
I have spent a long time debugging an application that occasionally goes awry, it ends up that the problem is that the comma delimited text files that I am looping through occasionally inserts a comma within one of the fields.
At any rate, I was loading the text file into Excel to try and spot the error which was of no help, somehow Excel parsed out the field correctly and didn't use that extra comma as a delimiter. Is there any way I can get my application to do the same?
And example field value is: "7-8-ALL (1,2&3)", but of course my split code turns this into two separate array values.
I am relatively new to VB. I was initially using fileopen, writeline, and fileclose to create, write to, and close a comma delimited file. But recently I attended a training course where the instructor mentioned that these old methods will be going away and I should try and use Streamwriter instead. I was successful in converting some of my code to StreamWriter when creating a simple text file using WriteLine.
For example: myStreamWriter.WriteLine(text). But this writes an entire line of text.
I cannot see to find any information on how to create a comma-delimited file using StreamWriter. My old code was something like this: Writeline(filenumber, field1, field2, field3, field4). How to do the same thing with StreamWriter?
my problem is for example if
1,50
1,200
are loaded in listbox1 and i split the "," and its value to textbox1 when i select the index 1 in listbox i get the same value as first index here is my code for load the textfile to listbox
Dim linereader As New System.IO.StreamReader(OpenFileDialog.FileName)
While (linereader.Peek <> -1)
ListBox1.Items.Add(linereader.ReadLine.Split(",")(0))
