View 3 RepliesIn my project I am using a session table. I am binding this session table to the gridview,in gridview row updating event.I keep the records of session table to a datatable and I use the code below code for updating:
dttable.rows(e.rowindex)("name")="arun"
dttable.Acceptchanges()
My problem is when using PageIndexChanging, I can edit in the 1st page of GridView without any problem, but in second page it is editing the one corresponding to e.RowIndex in the first page, so no change occurs other than the first page in the gridview.
I m' trying to select a row and then edit, and no error on debuggiing but the changes are not saved on the database

I have an application where I would like to allow the user to change one field in a datatable but leave the other ones uneditable. I am using a datagridview to do this but I can only make the whole table editable or not. The result should be an order form where you have a determined product and should only be able to change the number of items.

Any thoughts on this? Btw, this is my first time using a datarow, and I've recently been studying how to use ADO.net.

I had to switch computers at work to a laptop. My co-worker was using this laptop and we where both working on the same project using CollabNetSubversion to update the VB project. Well he left and reformatted his Laptop and now I am using it.
I took the VB project from my PC to the laptop and now every change I do won't show up if I run the program.I can completely commit out code for a form and it still runs!My trial version of VB ends in six days so I can't use the PC anymore.
I have a new project , It has two forms, I want to edit the properties so that the second form is the startup form, however, when I go to project properties I see the everything in the application tab is dimmed.

I'm trying to edit and save changes made to a row of a SQL table via Windows form textboxes. Right now when I run the app, I try to make a change to one of the textboxes, I click on the Save/Close button, but when I go to the database, the cell linked to the textbox is not showing the change.
Here is my code so far. I haven't gotten it to work correctly:
Private Sub btnSaveClose_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSaveClose.Click
'When Save button is clicked, build SQL Update command, connect to db,

I have been developing a Visual Basic 2010 .NET GUI based control application that has been growing over the last six months into quite an albatross. Suddenly, I have reached a brick wall where I cannot even edit a text label in the GUI without the following exception at compile time (debug) :
InvalidOperation Exception was unhandled
An error occurred creating the form. See Exception.InnerException for details. The error is: Index and count must refer to a location within the string.
Parameter name: count
This is entirely code independent - it happens if I simply drag a new control onto the GUI without even any code behind it - Once it happens the project is hosed - even if I undo or remove what I did.I have reinstalled VB from scratch on a new computer, and same problem. I am using Windows 7 and this happens with VB Express, Even with a trial version of Visual Studio Ultimate. I am completely stuck.
I have a text file pwd.txt comma delimited, I added in project resources, now i want to read,edit and insert in text file.

Is it possible to add a Datatable to the project, add columns to it, and then add rows with data in it that i can use in my project?

So i decided to make a units converter for my term's project and my teacher insisted on including the combo box in this project. I'm not really familiar with the combo box as i am still a beginner in visual basic. I've looked around and learned a bit about using the combo box but later i faced a problem. First i created a Main combo box and placed it in the middle of the form. I managed to use the select case command to make other combo boxes appear and disappear as i wish. I don't really know how to describe the problem, i want to make it that if i choose the input as a unit and the output is any other unit from two different combo boxes, the value in the input text box would be multiplied by a certain conversion factor and the result will be shown in the output text box

I have a set of code that builds a table as the user enters information. This information may be changed more than once before it is considered complete. After the user is done, I want them to click a button, and have that information entered into the SQL database where it belongs. Right now, the code I am using gives the error: "System.ArgumentException: This row already belongs to another table"
Is there a way to add a table to a table like this, or do I need to add each row to the SQL table as the user moves along.
Try
For Each row In Me.tblTraining
Me.DataSet1.docContent.Rows.Add(row)

I have created a simple project where I have two forms, one a data entry form where a client name, address, city, state and zip are entered into textboxes. Then, the user clicks a button to add all this data to the datatable via a newrow. The second form includes a datagridview to show the datatable. However, I cannot get the code below to work to update the datatable. I have a button to click to check to see if the data is entered and it returns an error that no row exists.

I have been using the Excel COM, so I am hoping that there is a way to do it this way.
