File parsers are great if you want to look at the text in a file, but not very useful if you actually want to use the data in the CSV as data in a table driven system. Depends on the need of your...

An easier route would be to open the dataset as shown, and then build a set of datarows from the table in the opened dataset using the DataTable.Select method.

I tend to lean in your direction with regard to coding practices. I have found that most people who use databinding to display their data fall into one of two categories: Those that are too lazy to...

Here is an article I found on MSDN that shows how to display data from more than one table in a dataset, in the same DataGrid.
HOW TO: Extend the Windows Form DataGridTextBoxColumn to Display Data...

It is absolutely not possible to reuse a datareader unless you execute it a second time.

The datareader is what we used to refer to in the "old days" as a firehose connection. It is a forward only...

the information for this is in the AssemblyInfo.vb file and is named <Assembly: AssemblyVersion("1.0.*")>

As I read your description, a few things come to mind:

Does your dataset have datarelations between the tables?

Have you attempted to run a select against your dataset?

I will be testing...

Have you heard of docking and anchoring?

I wrote them, I do a lot of work with Remoting and the only way to pass arguments from a server to a client, over a Remoting channel is to create a custom event args class, make it serializable and...

Yes, you are correct, if you want to pass information such as a string to an event handler, then you should create a class "CustomEventArgs" that has a string property, instantiate a new instance of...

ok, in your original post you listed some code and posed the question

In your InvokeMethod method, you are taking the parms and passing them as arguments to the method you are calling in the...

Yes, you have that part correct, and actually, based on what I have read from these few posts, everything should work, is there a problem that I am not seeing?

Yes, you are correct, anytime a mouse button is clicked, it generates a MouseClickEventArgs that is passed to the subsequent mouse click event.

Have you considered using delegates with the invoke...

What is it exactly that you want to do that the DataRow class does not already do?

Hey, take a look at this thread, I think it will answer your questions and resolve your issue.

csv and datasets

Ok, first of all, it shoud be known that I have written a remoting project in C# prior to attempting to write this one in VB. Armed with the previous experience, I figured that doing this in VB would...

Then this code will work for you:
Private Sub CombineArrays()
Dim Array1(3) As Byte
Dim Array2(3) As Byte
Dim Array3() As Byte

Array1(0) = 200
...

Well, for this to work, the data in your spreadsheet must follow a pattern that can be read into a datatable. This means that your data must not contain additional rows that might be text...

It appears from the code you provided that you want elements in Array3 to be the sum of elements from Array1 added to elements from Array2.

If my assumption is correct, then you must loop through...

The answer to your question, really, is a matter of preference. Both controls would work well for displaying of information. Both controls would allow you to pop-up a data form to edit a single...

Russ,

Yes, the provider assumes the first row is column headers, so as you stated, place something at the top that has no meaning. . .just as long as it follows the same delimited structure.
...

Russ,

The best way to approach this is to remember that Microsoft wants you to use anything that can be considered structured storage as a datasource. Bearing that in mind, Microsoft has provided...

ok, I changed the example and removed any references to a datagrid

John

remove the part about the datagrid

Use the AddHandler method, it's in online help, and if you can't find it, let me know and I'll provide an example.

Russ,

I don't know your level of experience so I also don't know what kind of problems you might be having trying to implement this with the information provided.

Here is a working example:...

Russ,

No, this would still work, you simply make the combobox's datasource the table, then set the DisplayMember property of the combo box to column(0) of the table, and the ValueMember property...

Is this a different problem from the help I have been giving you in the other thread?

Why not simply open your text file directly into a datatable instead of reading it in line by line. Here is the code to do that:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e...

Actually, as I was reviewing my post, I realized that I left a piece of code in there by mistake. Here is the corrected code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As...

If you carefully review my code you will see that every object you need to open the data and connect it to your grid is coded. You only need to change the file location for where your file is located...

Hey, do me a favor, let me know if you have an Instant Messaging client, AOL, Yahoo, MSIM?

Hey why not, most kids sleep through classes anyway, and then find someone willing to do their work for them. I would have hoped that Cassy would have opened the help file or at least did a search...

Howdy,

You need to add an imports statement at the top of your module:

Imports System.Data.Odbc

ADO is ActiveX Data Objects, which isn't appropriately named anymore because the .NET...

The sticky note at the top of this group has a link to 101 VB.NET Examples. Download that, there is an analog clock example which you could modify to create your meter face.

John

Cassy,

If you are taking a class on vb.net, I am sure your instructor had it in mind for you to "learn" something from this exercise. If I were to just write the code for you what have you...

Hey, this should work for you:
Private strFileName As String
Private Sub btnMove_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnMove.Click
strFileName...

Hello, yes, it's a heck of a lot easier than that :cool:

Before you begin, you have to realize that Microsoft in it's less than infinite wizdom regocnizes that any structured storage system is a...

Before I give you my answer, I need to know if you have already created Insert, Update, and Delete command objects and associated them with your DataAdapter?

I ask this because if you have then...

*bump*

Any one here got a clue ;)

I can post additional source code if needed. If you would like to see code from any of the other assemblies, I'll be happy to post.

John
