View 7 RepliesI have a text file with for example this data in it :
"19 Mar 2010","6:00","16:00","10","1","9","6.61","59.49"
"20 Mar 2010","9:45","19:15","10","1","9","6.61","69.89"
"21 Mar 2010","9:00","17:00","8","1","8","6.61","99.32"
I used " , " to delimit individual pieces of data and " " to denote end of line.I'd like to be able to split the files into lines and assign each line to an array then split each of those array strings into the comma " , " delimited data and feed each piece of data into another array ready for writing to a datagridview.
I've spent a while trying to get Split() to work but I get errors regarding converting strings to one-dimensional arrays Also the Split() method asks for a "ParamArray" but I haven't been able to find examples of other people providing them on the net any idea what those are about?
I have a VB project that reads data from SQL as well as pulls data from other files into SQL. I need to import a text file into SQL table; there is no headers in the file and table in SQL is already exists. I found a code in Forum and slightly modified it, but I'm still missing something. I'm not sure how to specify that the text file is delimited with "|" character? Also - since there is no headers - not sure how to import it into correct columns? On the code below I'm getting "Insert" syntax error; on prior version of the code I was getting "field F1 doesn't exist".

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 take a comma delimited text file and then select all unique records based on one of the fields in the text file. should i read the text file into a data table or just use a data reader?
View 7 RepliesSo i'm new to working with vba in access and i'm having trouble getting this code to work. What it is suppose to do is take a selected text file and read the original file into a list box. Then there is a second button that when pressed will convert the text file from a pipe delimited file into a tab delimited file and then show the changed file into a new listbox.
Option Compare Database
Option Explicit

this is how i would normally import a comma delimited text file into a ms access table:
sql.CommandText = "SELECT * INTO [tblMailList] FROM [Text;DATABASE=" & System.IO.Path.GetDirectoryName(Me.OpenFileDialog1.FileName) & ";HDR=NO].[" & Me.OpenFileDialog1.SafeFileName & "]"
sql.ExecuteNonQuery()
my question is, how can i do something similar for a tab delimited text file?

I'm trying to parse a text file. First I plan on extrcating each line, then extracting each field by searching for a tasb.When I use InStr to search for a (return for end of line) or (for tab) I always get a zero. But if I put in a visable letter such as a I got a 5.also I tried /r, /n and all return a zero.The file looks as follows:
ID Name
1 Patient
2 Bed
3 PatientSet

I've got a problem reading in a Tab-Delimited text file. There's an extra tab in one of the fields its reading it thats not a delimiter, and it's throwing off me reading the file into a table. This specific file does have quotations around that field though.
What would be the best way to take that tab out before splitting the row by vbTab?
Im reading each line in the text field like this, splitting on vbTab. X is a string array
text = x(J).Split(vbTab)
This is my first program that I'm trying to write. I have been trying to make an application to run a date filtered query against a SQL server and output the results into a txt file that I define. I believe that my code is close for getting the data. I cannot figure out how to actually write the data into a text file. I am trying to use the datareader and streamwriter, but I am not sure what to put in the streamwriter.Write() function to actually get it to past the lines in the text file.

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 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 have a text file that I'm reading into a listbox. I want to skip a line if it's blank. The following code works if I leave out the check for the line being blank. It puts the file in the listbox with no errors. However, when I include the If statement that checks for the line being blank, I get an ArgumentNullException in the Items.Add line when It gets to the end of the file.

I previously asked a question about my meeting planner app, and how to delete a specific entry in the array. Someone had the interesting suggestion of using a ArrayList, instead of a normal array. I am attempting to learn ArrayList, but to no good result. I can't even get the ToString method to work correctly to write what I want it to into a text file.[code]...
My plan is to have each of those three fields to have their own entry in the ArrayList, but when it is saved to text file, those three fields are comma delimited to a line for each appointment. Of course when the text is loaded, it will have to be converted back. Can anyone point me in the right direction or have any other method of going about this with the ArrayList?

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 3 RepliesHow to read a comma delimited text file? I want to have a new line for each row. For example it would be (author,book,location).
View 11 RepliesI'm having a problem where instead of reading a text file from the location string, I changed it to read the text file from the resource location and it breaks my program. I've also used the insert snippet method to get most of this code, so it is safe to say I don't know what is going on. [code]
View 2 RepliesI am new to the VB Forums. I searched the forums for an answer, but could not find one that exactly fit my issue. I apologize if I missed it. What I am doing is I'm pulling strings of text from a backslash-delimited text file and throwing it into a (Of String, Array) dictionary. This info is then displayed, added to, removed from, through the use of the form. Changes to the entries (new, old, or otherwise) then need to be written back in the same delimited format to the text file.

I have a program that generates text tab-delimited files with a header row and sometimes a units row followed by data.
Example:

Name Name Date
Michael Jordan 6/6/66

I would like to be able to perform SQL queries on these files. How can I connect to a text tab delimited file to either pretend it is a database table or import it into SQL as a table, preferably through VB.NET? I could have 300,000 rows, and the fields are all numbers, not text... I have manually imported these files into SQL before using management studio, so I know it is possible but I would love to be able to do it programmatically.
Is there any way I can get the SQL code from this process because it does exactly what I need it to do but it is manual. There is an SSIS package that I saved, but I do not know what that is.
I am just trying figure out a record import program from text file into access database using Microsoft.Jet.Oledb Provider 4.0 and Vb.net. And it seems easy but my problem is different. In the text file, records are not delimited.
Format of the text file:
Field Name & Size
Date[Date,ShortDate]FirstName[20]LastName[20]Sex[1]Age[2]
[Code]....
Can I put delimiter programmatically while reading the text file using stream reader and later simply import the whole file in DB.
Is there a way to open a semicolon delimited text file to a datagrid in vb.net??
