View 1 RepliesI 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

1)How do you export the data that is displayed in a datagrid to Excel.
2)How do you import data from an excel file, and fill the datagrid with that information.
I have a weird situation. I have a C++ code that overloads the +,-,* operators and exports them in a .DLL file. Now, I want to import those overloaded operators from within VB.NET code. So it should be like this:
<DllImport("StructDLL.dll")> Public Shared Function
Operator +(ByVal a1 As A, ByVal a2 As A) As A
End Function
So what I'm trying to do above it just import the lovely overloaded operator + from the DLL.Note that the operator is already overloaded from inside the DLL, so should I import it as a Function or as an Operator like this?
<DllImport("StructDLL.dll")> Public Shared
Operator +(ByVal a1 As A, ByVal a2 As A) As A
End Operator
The overloaded plus operator is supposed to add structs. So the DLL is programmed to work on structs (C++) and I want to import it in VB.NET to work on Structures.
I'm brand new to this forum. i have a question. i wrote some software a while back and now have a few new features I need to implement. this software currently makes use of "application settings" to store all of it's settings. Which works just fine.
I have a client that has about 40 users. He wants to be able to share his settings (that he set up in his copy of the software) with all of users. Preferably by distributing a copy of a config file that they would be able to import into there software.
I've seen a lot of posts over time relating to importing and exporting CSV. Most of the answers involve using TextReader.readline and String.split, which will not work with any but the simplest data. When you are writing for users who have the expectation that your application will work with anything they export from Excel, you will have to cover all the CSV bases.
I hope that this post will give you a clear idea of what you're involving yourself in when you decide you need to read a CSV file. The characteristics of CSV data are:The comma character is used to separate the fields. (This is obvious, but I thought I'd start with a couple of obvious points to warm up) The last field on the line is ended by the end-of-line character or the physical end of the file.Any field that contains commas, double-quotes or control characters will be surrounded by double-quote marks. Any double-quote marks within the field will be "escaped" with an extra double-quote character. For instance, the value Paul "Chuck" Norris would be converted to "Paul ""Chuck"" Norris".After the opening double-quote ANY character is valid. Including line breaks. This is why you can't use readline.I have a parser class that works nicely and I'll post that on this thread in a little while, along with some notes on using it.
I have a requirements in "Windows form exe" that when we click on the exe, the data from the Oracle database should be exported to another Oracle database and also the data that has been exported should be emailed with excel attachments to intended recipents.
I searched but couldn't get the code as such and also i am not able to implement the functionality.
I have a windows application that exports data from a datagridview into excel. Now this data can change based on what a user does in the datagridview itself. An example would be out of 1,000 files the user can sort through using DataGridViewAutoFilter to search for a handful of rows, say 50 or 143 or whatever.
The user then clicks on the button which exports to the excel worksheet. I'm looking for some help on getting a subtotal count at the bottom of the export. I would like to be able to have some additional code in place that would subtotal the records that the user exports into the worksheet. Let me show you what I have so far:

I am building a small Windows Forms application. I need to 'read in' CSv files into the application.
I am using StreamReader to read the CSV files into the application. That is no problem. On my Form I have a text box, 3 Buttons and 2 data grids. With the first 'browse' Button I am using OpenFileDialog to select which CSV file I want to display in the first grid.
Then I want to use a 'convert' button to display the information from the CSV file in a much more 'user-friendly' manner in the second grid. Lastly I want to use my 'export' button to export the converted file to excel.
I am working on a vb.net Windows Forms application.I want the application to import Visual Studio Solution files from versions 2005 & 2008 (elsewhere on my Hard Disk).I am using Visual Studio 2010.

I aso know that it will find files - 'Microsoft Visual Studio Solution File, Format Version 9.00 # Visual Studio 2005'.Under is my code thus far. Maybe someone can give me some advice as how to make sure that the applications returns the correct Sln files?

I am using Visual Studio 2008 and looking for an efficient and hopefully straightforward approach for exporting data from a DataGridView to Excel. If doable, my preference would be to export the data to Excel without instantiating an Excel application. I found some code on the Microsoft support site that is fairly accessible but the example shows how to export just a few pieces of data. Would someone be able to demonstrate how to modify this code to so that it could be used for large amounts of data (for example, data from a DataGridView).

Dim sConnectionString As String
sConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" & _

I'm trying to export the content of a data grid to an Excel file. But here is my problem:
1. If I use a Data Grid which was set to allow Adding and Editing of columns ( this appeared the first time I add the control to the form) , the resulting excel file will show all the content of the data grid, except for the Headers ( Column names) .
2. If I use a Data grid which was set to disabled adding and editing of columns, the resulting excel file is lacking the bottom-most row of the data grid content. The Headers are also not included.
I cannot choose Option 1, since the data grid must not be editable by the user. I cannot choose option 2 since the last row is being omitted. Another thing is that the Column Names ( the data are coming from a MS Access File) are not added into the Excel File for both Option 1 and 2.
Here is the code I'm using. I found it from the net and tried changing the values of i and j but still I can't get the result I wanted.
For i = 0 To dgreport3.RowCount - 2
For j = 0 To dgreport3.ColumnCount - 1
xlWorkSheet.Cells(i + 1, j + 1) = _
dgreport3(j, i).Value.ToString()
