Take text data from a small file and display it in a form using a DataGrid.
I am trying to make the program so it will allow the user to choose which file to open (this part already works). I have stepped through the code and found that the rows are being added to the table, but when the action runs to completion my form has no data on it. Here is my code (forgive any code shortcomings as I have exactly three days as a VB.NET programmer).
It appears my connection to the db is correct when I select different options the datagrid displays the correct number of records. So I am not sure why I can not see the data in the grid.[code]....
I am attempting to display a datagrid with the results of two different queries. I want one to display, wait two minutes,display the second query, wait again then start over. I am unable to get either grid to display. If I run either query individually without the wait they display perfectly. How can I do this?

I'm having this weird problem with my windows application, I have fields for entering data into an underlying access database, my problem is after clicking the submit button upon entering the first data it shows neatly in the datagrid but subsequent data entered repeats what was initially entered into the datagrid.
Private Sub BtnSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnSubmit.Click 'Sets Null Fields to 0
I have a datagrid where i am entering numeric values. at design time, i have set the format for each column to C2. So at run time, When i am entering the values, it is being set in the current format. When i am displaying data from sql, instead of showing 400.00, it is showing only 400.
i know the record position or number of datatable and the same table is used as datasoure to grid. i want to find out the row number in the grid for current record in datatable. in case grid is not sorted it is easy but if grid is sorted then row number change in the grid.
I have 5 textboxes embedded in a datagrid that require a date format (mm/dd/yy), but can be left empty if user doesn't have date.User can poplute these textboxes for multiple records and hit submit button.On the submit i loop through the grid. If dates are populated AND they are in the correct format then I call a stored procedure that inserts the record into a table.If any of the dates that are populated in the textbox is not a date or in the incorrect format I need to display error message in a label.I got all this to work, but if it throws error message all the data in the grid is wiped out.How can i keep data in each textbox and still display the error message?
I refreshed my data sources to include additional items from the SQL Server databases and it appears that my entire data source from my VB.NET project disappeared.I am using Entity Framework. I may have clicked on something wrong, not quite sure. Unfortunately I can't recreate the Data Source without creating a new Entity and Data Model.I can delete the entry in the App.Config file and recreated it, however things aren't quite right.Is there a way that I can recreate my Data Source from the entry that is in my App.Config file...since that appears to have remained intact.BTW, I can go to my Data Model and successfully refresh from there, however my project isn't connecting to the database so I have quite a number of errors until I can get reconnected.

I am trying to display an excel spreadsheet on a page using datagrid, but for some reason it is filtering out some of the cells, leaving a blank space instead. Also, the "$" sign won't show up in most of the columns.Could someone please take a look at my site and file, and give a suggestion as to why this would be happening? I've tried a bunch of troubleshooting on it, with no success.

Here is the code that I used to import and display the data:
Code: Dim sConnectionString2 As String sConnectionString2 = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" _ & CasePath & ";Extended Properties=""text;HDR=Yes;FMT=Delimited"""
[code]....
The problem is, all of the data gets displayed correctly except for the ip address. It gets truncated to "134.1892". How can I change the formatting for the "Local Address" and "Remote Address" columns.
I've tried a few different methods I could find in order to connect my VB .NET program to a book store's database. While I've been able to connect to it and display the contents of its tables in a DataGrid, I need to be able to search the tables and display specific records, depending on the contents of appropriate the adjacent text boxes.[code]This is a code I've used for a very similar process, just really aims to search a different field in the table. If this is easier to adapt into a code that allows searching and producing specific records in a database, please use this one.
I have a datagrid displaying details from a sequential text file. I need to have a button to search through this textfile and display only that line of data in my datagrid. I am using an input box to enter the persons name they wish to search for. The datafile contains several lines of info like : John, Murphy, 35, etc.
I am trying to display the contents from a datagrid into a textbox, there are two collums that I want to display. I can get one collum to display by using the following code.
I would like to develop a VB.net application that includes VB.net datagrid displaying records with Checkbox in the grid operation.Also would like to learn, available datagridview options/events for more friendly programing with VB.Net datagrid.

I want it so every time I click an ITEM in the Listbox it displays ALL the data into the textbox. I know there's an easy way using table adapters and binding the listbox, but I'd prefer to do it this way for my project.
Modifying data with the ListView's EditItemTemplate by programmatically settings its DataSource property and calling its DataBind method. I don't have option to use data source control for ListView. All ListViews are bound with data from code-behind. So, I have to handle the Edit/Update mode of ListView manually. [Code]
I'm trying to connect a VB application (2010) to an MS Access DB by adding a data source from the data menu but I receive this error message "The connection you selected uses a local data file that is not in the current project.Would you like to copy the file to your project and modify the connection ?
If you copy the data file to your project, it will be copied to the project's output directory each time you run the application" and the options are (yes , No , Help)
If I choose Yes I will not be able to make the application 'device independent ' since it will not be copied under the bin , and if I choose No , changes won't be applied to the DB
how to use the VS 2010 IDE tools in a way the Microsofties didn't specifically intend. But since this is something I immediately tried without success.
I have defined a .NET 4.0 WPF Application project with a simple class that looks like this:
Public Class Class1 Public Property One As String = "OneString" Public Property Two As String = "TwoString"
[Code]....
The expected result was that "OneString" would appear next to "One" and "TwoString" next to "Two" in the running window.
The question is: Why didn't this work? What will work instead? If I put bindings in a DataTemplate, it works. Blend, with its sample data stuff, implied that this should work, but it doesn't.
I have 5 combo boxes that need to show the same list of items that come from a single dataset table. I have managed to bind the datatable to the combo boxes no problem at all.. but when I run the application and select an item from one of the combo boxes all the others change to the item I selected. After some research I believe that this problem is something to do with using the one datasource so I have tried assigning the dataset datatable to 2 different variables and used them as datasources for 2 of the comboboxes but the same still happens.
A work around to this I can see is to call the same methods and SQL select statements 5 times over to get individual datasources for each combo box but this doing that sounds crazy to me. how I can get around this easily? Code snippet below shows 2 combox boxes and their datasources. I'm using VS2005, .Net 2
I have a combo box with a data source. This box shows one column of a table and allows me to select one item.Next, I have an ordinary text LABEL that I need to put text from another column of the item selected above.I tried to set the data binding field of the label, but this grabs only the first row or data and shows the selected column. That is nice, but I can not figure out how to update the selected selected ROW when the combo box item is changed.In this case the combo box lists a bunch of inventory parts. When I select a specific part, I need the change the text in a label to show the manufacturer. (like a sub-form). This same behavior will be used in several other places, but the relationships can cascade.
SELECT pkt.fldPackageID, pkt.fldPSID, pkt.fldQuantity, pkt.fldQuantityUsed, pkt.fldRetail, pkt.fldPK, ps.fldName FROM tblPaketRow AS pkt INNER JOIN 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.
