I have a problem here. In my window form there is a datagridview. Inside the gridview there are rows with data. Some rows background color is yellow, and some is white. I'm wondering whether there is any solution to sort the datagridview by rows background color so that yellow color rows is showing first.

I am trying to add a checkbox column to a DataGridView in a simple window forms application.
I am pulling back some data from a database using ADO.NET, putting into a datatable, and then setting the datagridview datasource to the datatable. I then want to add a checkbox column as the second column. So far I have this code that seems to work:
' Code here to connect to database
Dim da As New SqlDataAdapter(cmd)
Dim dt As New DataTable
[Code].....
This code 'works' and I get MyDataGridView to show the data with the checkbox column in the correct position in the table.
However, for some reason, I cannot check any of the check boxes in the DataGridView? I have tried lots of things (e.g.altering the readonly state of the column) but cannot get it to work.

View 1 RepliesAs Autodesk is going to discontinue VBA for their Inventor product in the near future I have been looking at other ways to run VB.NET in Inventor. To date it doesn't look like VSTA will be the replacement. Automation from an External VB.NET app is certainly possible, but leaves something to be desired for speed and integration. Compiled Add Ins are the Cadillac of choice but can be a royal pain to debug and develop. Autodesk now provides a lightweight VB.NET script interface called iLogic. It's main purpose is to allow extreme customization of Solid Modeling parts. The code actually resides inside the Part Model file.

I have a big datagrid view, with datasource set to datatable with 15 columns, and about 350 rows.
When I change the size of the window with the datagridview it isn`t resizing smoothly.
How could I make the resizing more smoothly?
I am using a Thread object to perform a function. This function performs a task and displays its progress in the gridview (like adding rows changing text etc )
The reason I am using a thread for this function is that there is a cancel button on the form. While the task is in progress, user can click on cancel to abort it.
Private Sub BtnStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnStart.Click m_Thread = New System.Threading.Thread(AddressOf myfunction) m_Thread.Start() End Sub
The function works fine and thread is completed. But calling any method of datagridview after thread is completed ( outside the worker thread ) generates an error- "Error creating window handle".
That's probably because i am not using the invoke method of datagridview for calling its methods or readingwriting properties Do i have to create separate delegates for all the methods properties used in the function ( worker thread)
I have now got a DataGridView on a form with a toolstrip which automatically created for me when I dragged the DataGridView from the DataSources on the Solution explorer window.

View 2 RepliesI want to know if VB.Net already has a control like this before I start wasting time building my own. I have a DataGridView that shows the row error symbol in the RowHeader if the update to the database is unsuccessful for that row. Currently, if you hover the mouse over the error icon it will show a default tool tip to display the error text.I would like the user to left-click the RowHeader and a small popup window will show the error text. Then when the user clicks somewhere other than the popup window it will disappear just like a context menu. do I need to build a form with no borders that has a large textbox in it, then setup an event so when the form loses focus it closes? Or does a context menu strip have the ability to support a large textbox? Or do I use a splash screen?
View 4 RepliesI have a datagrid view containing a customer list that if if double click on a row it brings up a customer maintenance window. Once I hit a save bottom on the second form how can I automatically update the database, refresh the grid on the initial window but remain on the same row on form1 that I double clicked on in the first place. Currently I am re-loading the datagrid on the initial form with all the data once I close the second window down.

I was wondering if it was possible to create a program in vb that recognizes a window/form and performs certain actions based on that. Basically what I want to do is create a program that auto fills out and clicks buttons on an install wizard to automatically install a program. I guess like some what of a macro. NOTE: I will only be using this only one installer, since I have to install this program multiple times.
View 7 RepliesHow do I make the form send keystrokes such as Tab, Enter, Left Arrow etc to itself without interfering with other programs? If I use the SendKeys.Send method, it would send it to whatever window is opened. Is there a way to only work with the form? Very quick random example: Let's say I have 5 textBoxs and I click the 'Tab' button 5 times. What would happen ?
It would change the focus from one textbox to another right? Can I make this happen automatically ... like make it happen in the background and only to the form itself. So If I'm typing something on Notepad, I don't want to receive those 5 tabs. By the way I know I can use this code to change the fofucs, but remember its only an example.

I've got a question about attachment field (as OLE object/attachment) in Access Database and Visual Basic 2010. I would like to know, is there a possibility to use attachment field in the same way, in VB like in Access Database? What I want to do, is to make an application (connected to Access Database) for users from my company, that will allow them to open "Registration Form" and fill all required fields, and also add PowerPoint Presentation as attachment.
What is most important, I would like to have an access to this presentation.
Project Path:
Employee opens Application/Window Form --> Fill all required fields + attachment field --> I have access to the presentation from Access Database/or another Window Form (I can Open/Edit/Change the presentation)
So, what I would like to have - Window Form with attachment as icon, but after upload (by employee/other person) it has to be in the database.
