I'm facing a problem reading .csv file into datatable. The machine on which i install my window service ( which reads the csv ) is Windows Server 2008 R2.The error i get is : The 'Microsoft.Jet.Oledb.4.0' provider is not registered on the local machine
Below is the code i use to fill the dataset from .csv file :
string connstr = "Provider=Microsoft.Jet.Oledb.4.0;Data Source=" + System.IO.Path.GetDirectoryName(arrFilesName[iCount].ToString()) + ";Extended Properties = 'text;HDR=YES;FMT=Delimited'";
OleDbConnection conn = new OleDbConnection(connstr);

I also looked at the other option i.e. Micorosft.Office.Interop.Excel but that also needs Excel installed.So, I would like to know that, is there a way to read a .csv file without having Microsoft Excel install on the machine.
What I want to achieve is to Bind just some of the properties of a Control to a DataTable object.Let's say I have a Label on the Form : "MyLabel1".MyLabel is a Class that inherits from Label and adds a property "ID", an Integer, to the base class.
I want to Bind .Left and .Top properties of MyLabel1 to a DataRow in my DataTable, and I want to see them updating, everytime I change MyLabel1 location on Form. I put description and full code, so everyone can test it in minutes :
I have :
--> A Form, with a DataGridView "DGV" : The DGV is for showing at real time the desired properties of the controls I want to bind ( in this case, just one control : MyLabel1 ).
--> MyLabel Class :
Public Class MyLabel
Inherits Label
Private m_id As Integer

I'm currently developing an application with a reasonably complex DataGridView that allows the user to build the lines of a sales document: Quantitiy, Description, Price, etc with some additional fields to help calculate price based on cost or discount i'm sure you get the jist - all this means we're not just diplaying data but adding and manipulating it - It also means there's mainly decimal fields, nit just simple text fields
Now, i'm new to VB.net, so i've perhaps done things a bit backwards during my learning curve, namely designing and coding my DGV before creating the underlying database table and binding to it - so as i'm sure you can image there's a bit recoding to do to allow for the fact that it's now bound to a datasource.
I'd got the DGV working just how a wanted it to, but now that i've bound it to a datasource i'm hiting multiple problems with: Formating the appearance of figures in the DGV Problems with blank fields while enering data (before the i try to save the data back to the database) How the DGV is functioning - it seems to behave differently when adding lines to a new sales document than it does when adding lines to an existing sales document
And given that when saving edits to an existing line i need to provide a valid update command i'm begining to think that it might be easier to scrap the databinding altogether and just Select, Add and Edit the database with code rather than binding the DGV in the IDE
I've read various threads about avoiding databinding due to it's limitations, but i've also read that it's far better in later versions of Visual Studio and .net. and i'm using VS2010
I'd just like some advise as to whether my gut feeling is right or whether i should persevere with databinding the DGV. i've noticed some quirks of databinding while working with other controls such as text and combo boxes, but i've overcome these and the result seems to be easier than coding the data transfer manually.
But i'm really struggling with databinding the DGV and the fact that i'm dtatbinding to a seperate table to the rest of the controls is leaning me away from databinding
I'm trying to populate the list of a combobox by binding it to a datatable. Also, I want the selected value of the combobox to be bound to an object property so that when the selected value changes, it's automatically updating the object. However it's causing an error at runtime: "This causes two bindings in the collection to bind to the same property.
Parameter name: binding" I thought binding the dropdown list to a datatable and the selected value to an object were different properties but obviously I'm not getting it right.
Code:
Private Sub PopulateSiteSelect()
With Me.PlanSiteSelect
If _Plan.PlanID <> Nothing And _User.UserID <> Nothing And _Plan.Category <> Nothing Then

I have a datagridview bound to a datatable setting its datasource property to the datatable. I would like to have a child form that contains a list of columns associated with the datatable that contains a checkbox that will allow the user to hide and show the columns ( I do not know the best control to use here) (I assume this is the easy part as All i need to do is loop through each of the datatable's columns to get the column name)
now I would like save these visible columns on some event like form_closing so that the next time the user opens the form up it will remember the settings
So I'm working on this project. I got around 60 images or so which I need to OCR, then I'll be inputting that data into my program which formats it and inputs it within this DataGridView. Now, I need the same data to be exported into an excel file. I saw several tutorials online but none of them are current (for VB 2008 or 2010). Either that, or they're not for VB.NET Windows Form Application. [I'm using VS 2010]
I'm fairly new to Datagridview as well. Just learnt how to add data to datagridview using this tutorial:
http:vb.net-inform...ridview_add.htm I was hoping you could help me out with where to start once I get my data all set up in the datagridview?
Can anyone help me on how when I click on a button in VB, it will browse an excel file that will display its information in a datagridview..Then when I click on update after it will save the result in the datagridview in an access database.

View 2 RepliesI have done a google and see that many people have asked the question on how to export a Datagridview to a Excel (.xls) file. For some reason I cannot seem to get it to work (i have gotton the program to open an Excel and save it, all hidden in the background). I use a bit of the coding from this source code [URL] but modified it and incorporated it into my program. It connects an OLE Database connection with the excel sheet... but what i want to do is beable to alter the sheet in the datagridview and export it back to an excel sheet. I am not trying to sound pushy when i say this but... if you download the source file i am using you will get a really good idea of my situation..

I can load the data into a datatable just fine, but I'm having problems figuring out how to open the excel file BEFORE it's loaded into the datatable so I can "Clean" a column of data the program reads from that can potentially have hidden characters. Below is what I have so far.

How to bind entire grid in to excel without looping..
I'm trying to figure out what would be the easier method for what I'm trying to accomplish. What I have is in, on the main form, a datagridview that is bound to an xls file. I then have another form that the user can import/paste data to another dgv. This content then needs to be appended to the end of the main form's dgv. Would it be easier to add it straight to the dgv and then save it to the excel file or save it to the excel file and reload the dgv? Or does it matter? I'm not exactly sure how to do either method but I figured I would start here.
