Exporting / Importing Data From / To DataGridView To / From CSV Or Text File
Jul 15, 2008I want to export data from a DataGridView to a CSV/text file. I then also want to be able to load that same CSV/text file and populate that same DataGridView at a later point in time. My information is loaded into columns in the DataGridView. That is, I am not using rows to represent records, I am using columns. As such, I need to load all the data in each column and export this, by column to the CSV/Text file. Likewise, when I load the control from the CSV/text file, I need to load each column with this information.How do you export/import from/to a DataGridView controlHow do you organize the data in the CSV/File

View 1 RepliesFormat IBM Date Field In Datagridview?
Aug 5, 2010I have a simple VB program that is using the IBM ADO .NET data provider. I've set this up so the data is used by a data adapter and fed with a standard DS. I've manually done the commands to acheive this in code. I tthen use the DS as the datasource for my datagridview. I'm having one issue and that is with a date field. It uses an "old" IBM date of CYYMMDD, century, month, day date in a numeric field. So my dates look like this for instance in the datagridview:
1100804
My question is this, is there any easy way to format them into mm/dd/yy after the DS has been put into datagridview but not yet displayed?
I have done this using the dataread object and can work out a format that way, but I'd have to recode what I already have done.
Some code:
' use the command & connection to fill the data adapter
adpt.SelectCommand = New iDB2Command(cmdText, Db2ConnectOSLD1F3)
' fill the tabel adapter

Exporting DataGridView To CSV File

Extracting Month Value From A Date Field In A Datagridview?
Mar 11, 2010I'm not sure if this is simple or not, i'm still a student programmer. Basically I have a datagridview that has a date column. I'm wanting to compare the month value from a cell with the current month as an if statement condition. Something like this:
If Me.DataGridView1.Rows(i).Cells(7).Value = currentMonth then
...
End If

Forms :: Writing Data From A DataGridView To A Text File?
Feb 17, 2010I have been using this code, see below, to try and write data from the DataGridView to a text file. It works but it puts an extra comma after each line and thinks that there has been another line so puts an extra 4 commas on a new line. So the text file looks like this:
9,Here to There,1,15,
8,Hell to Heaven,16,34,
I'm looking for any help for a way to get rid of the extra commas or an entirely different way of doing this whole process.

Jun 20, 2012I have two text files with various columns, each column is separated by a tab (" "). What I'm trying to do is the following:-If the values in text file 2 column 1 does not contain any value in text file 1 column 1 then add that field to text file 2 and add a 1 to the second column, like so
String 1 If the value in text file 2 column 1 already appears in text file 1 columns 1 then just add +1 to the value, so if the above value is already in Text File 1 Column 1 and Text File 2 Column 1 then it would appear as.
String 2 And if it was to happen again then
String 3 and so on.I have the following coding so far.
Dim lines1 As New List(Of String)(IO.File.ReadAllLines("File1"))
Dim lines2 As New List(Of String)(IO.File.ReadAllLines("File2"))
IO.File.WriteAllLines("File2", lines1.ToArray) & +1)

View 5 RepliesCreate File From SQL Text Field
Jan 16, 2009I have been trying to figure out how to take text i have in a SQL text field and create the correct document from it. Here is the info i have in SQL: MIMEType is a string field that contains one of the following "application/pdf", "application/msword", "application/vnd.ms-excel" or a few others. DocumentBody is a text field that looks like "0M8R4KGxGuEPgADAP7/CQA" this continues for quite a bit. FileName is a string field that contains the original file name such as "test.doc" or "test.pdf"
I have tried using the System.IO.FileStream and System.IO.StreamWriter but in the document it actually writes the text that is desplayed in DocumentBody. I assume I am missing some way to decode this using the MIMEType but i just can not seem to find it.

View 7 RepliesExporting A DataGridView To Excel?
Mar 13, 2006I have a datagridview(DGV) which contains data based on a user selections from a pre-defined dataset
In point form:
User starts program
program builds datatable
user opens file and program read all data from file into the dataset.datatable
user defines the data they want to see
program displays datagrid based on dataset.datatable and user choices. (basically it displays the whole dataset and removes unwanted columns
ecords)
I want to be able to export the datagrid to excel (not sure which method yet). I have tried the excelexporter component i found somewhere on the msdn forums (it exports the data to look exactly like the datagridview) but its painfully slow. It exports something in the region of 100 records per minute. Most of the time, the datagridview can contain anywhere from 3000-32,000 records. As such, at 100 records per minute, the excel generation can take updwards of 50minutes. Unacceptably slow for the purposes of the program.
What do people recommend as the best method to quickly dump the contents of a datagrid into excel. By quickly, im talking at the speed of about 10,000 records per minute. In all honesty, anything over 5000 records per minute will be fast enough, but the quicker the better!
Is there a way of creating a new dataset.datatable that is built of the contents of the datagridview and then building an excel sheet by connecting to the new dataset?
I would like to be able to export to Excel 2000-2003 at a minimum, but if i can do excel 97 as well it won't hurt.
