Im a newby in creating programs using vb.net. Currently 'm creating an program that will display array data to datagridview. Can somebody help me how to do it?
View 3 RepliesI am working on a project. Part of my project requires me to capture data, for example, email address, from certain rows/columns of a datagridview(form2.vb) and displays them in a textbox on another windows form(form1.vb) with a click of a button(Add Contact button). The problem is the datagridview on my form must be able to display databases by making a connection to Microsoft SQL Server 2005 but so far, i have not been able to do that. I have seen many codes with regards to my problem but i do not know how to implement it.
Below are my codes that i have written so far. My program's limitations are not being able to display databases from Microsoft SQL Server 2005 so i created the statement below to add columns and test my codes.
DataGridView1.Columns.Add("CustName", "CustName")
DataGridView1.Columns.Add("Email", "Email")
[Code]...
I've been asked by a local window cleaner to design a small utility that can display a grid of customer data, sort them, and then export it out as a formatted .txt or rtf file.

I am teaching myself VB with the use of a basics book, but I can't seem to find help for my project in the book.I am working on a project in which I have to open data from a csv file and use it to make graphs and analysis. The data is displayed in such a manner:
row 1: column titles
row 2: units
row 3-100: data
what I want to do is create arrays for each column in the csv, populated with the data.
I would like to create a sorted array of data. This is what I would like to have: A Textbox with numerical values, example: 72, 101, 108, 108, 111, 116, 104, 101, 114, 101, 046, 72, 111, 119, 97, 114, 101, 121, 111, 117, 100, 111, 105, 109, 103, and 163( these numbers will very and the amount of the numbers will very as-well).

tblProdukDanService AS ps ON ps.fldID = pkt.fldPSID
WHERE (pkt.fldPSID = @param)
I'm trying to display the results in datagridview,i drag from the data source in vs 2008..I can't figure out to do that.I use this code to set the @param on form_load event.
Me.TblPaketRowTableAdapter.JoinTable(SalonDataSet.tblPaketRow, modCommon.s)
I have a series of arrays each containing various info.
Is it possible to display this data into a datagrid and then sum op the totals?
I'm pretty new to the EDM, so bear with me. I have a windows form that has a DataGridView on it that's bound from the EDM I created. I figured out how to update my changes fine, but it's when the user creates a new row that I'm having a problem.I tried numerous ways and many google searches, but came up with nothing so far.

Recently I have learned visual basic 2008 express edition and developed programs for data crunching and analysis. The VB 2008 express edition has microsoft visual studio 2008 v. 9.0.30729.1 SP and .NET Framework version 3.5 SP1. Now I want to create x-Y (date-Y value) graphs using the crunched data stored in an array list simulating a data base access. I download and installed the "Microsoft Chart Control for .NET Framework " and try to learn to use it within the VB 2008 express edition using the tutorial. It seems that the chart control did not get installed?
1. Do I need at VB 2008 professional to allow using the chart control?
2. Why after installing chart control, there is no change on the items under the NET components within the Toolbox>ChooseItem>.
3. How do I get to use the chart control under VB 2008 express edition.
4. Any code available to generate versatile graphics without using the chart control? Because the chart control has tons of classes already it seems the best is to just use the existing and downloadable chart control?
I'm new here but I've got some questions. First of all how do you add data to a datagridview? I have an Access database and there are some records I want to add to the datagridview by use of a query.

I'm using Visual Basic 2008 in Windows 7. I've added a datasource to my project and dragged an element, a sort query, from Data Sources onto my form. It automatically created a DataViewGrid and placed this statement in my form load event: Me.SortBillsTableAdapter.Fill(Me.DoBills_2009DataS et.sortBills). The datagrid view shows all the fields/columns. When I preview the data element from right clicking the element, selecting Preview Data, and click Preview in the Preview Data dialog box, the data appears. But it does not appear when I run the app. The datagridview is empty. What am I missing to get the data to display in the grid at run time? I did notice that in the properties for the dataviewgrid the databindings property is empty. Is that right or am I supposed to do something there?
