Open Form Based On Value (inside Column) In DataGridView Control
Jun 9, 2011
I am developing a software using microsoft visual studio basic 2010. I used a datagridview control to display a list of data from product table. What I want to do (actually I am not sure how to do it, or is there a way to do it), when I choose one of the value in one of the column inside the table, I want it to open a form that contain data(details) based on that value.
How to do it? How to call the value that I pressed, so it can be used to open a new form containing the details of that value
Example of the data: (the "system" column) SYSTEM
topaz
nex1300
Nec
If I pressed "topaz" system, it will prompt me to a new form containing the details of that "topaz" system.

I have a data gridview on my windows form with 4 columns. Now I identify a column as followed:
Dim item1 as String = DataGridView1.Item(1, index).Value
So now I use a number ( In this case: 1 ) for the column index, but I want to make it a bit more readable so now I want to obtain the column index based on the datagridview column name.[code]...

I have a datagridview with several columns, but what I�m trying to do is sum km2 column based on date. I�m using the following
Private Sub Form3_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.CadastroSeqTableAdapter.Fill(Me.Db01DataSet.CadastroSeq)
[Code]....
The query is grouping by DATE (data), this OK, but the km2_FF values not, is not showing anything. To be more clearer, this datagridview has different values of km2_FF for the same date, I want to display the total of km2_FF for each day.

I have a SQL database, with some "status" strings. For every status I need to display a .bmp image .
I'm displaying the data from the database via DataGridView with LINQ. In order to display the DGV I have this code:
Me.MyTableAdapter.Fill(Me.TestdbDataSet.MyStatusList)
I was thinking to add another column named "Symbol" and based on the "Status" column to format the cells of the "Symbol" column to display an image.
I edited the DGV, and add a new image column.
I created a directory in my solution called "references" where I put all the .bmp files
I don't know how to do this. My first thought was to put an expression in the DataTable Properties, but I didn't manage to make that work. Another way is to format the cells in the "Symbol" column, and again I don't know how to do that. I tried with "Select Case ... Case ... End Select" with no success.
LE: Should I Insert the .bmp files into SQL database (varbinary(MAX)) If yes, how?

I am working on a project using Visual Studio .NET 2003.I am trying to open a second form based on user response to Yes/No Message Box. I have tried two different code variations. The first variation is:
Dim MsgAnswer As Boolean
MsgAnswer = True
Dim MsgRes As DialogResult
Dim CustomerInfo1 As New Form
[code]....
With this code I get an exception error: An unhandled exception of type 'System.NullReferenceException' occurred in OrpheyOnOpen.exe Additional information: Object reference not set to an instance of an object.

I followed an example to add a custom control (multicolumnCombobox) to my datagridview.[code]Ok, this is fine and dandy, for it adds the custom control to column 2 and row X of that loop.... Now, when I actually use the control for lets say row 0, how do I get the row 0 cell 2 value to be the same as the custom control??I have no way to communicate between the custom control and the datagridview cell.

I have a customer which as a Visual Basic Project in single instance mode with a wired presentation logic.
The main form contains a TabControl with mutliple TabPages.If I click on TabPageA another form is shown in front of the Form and resized to have the same size as the TabPage.
If I click on TabPageB the first form is hidden and another form is displayed.So basically for the user it looks like you have a TabControl with different TabPages which is not the case.
I tried converting the Forms to UserControls and put them inside the TabPage, but, thanks to the SingleInstance app, this would take a whole lot of refactoring. I tried it but eventually gave up because of many many runtime errors and I don't want to put any more effort in this.

im new to coding (started coding last month) so im a little stuck on how to do this, im making some emulation programs to learn coding with, and a part of it is to point the app to a .iso/.bin file and scan the data inside of the iso/bin to check if a file exists.[code]My issue is i cant find any class examples, or any information etc on how to code it so my application can see the data inside of the iso/bin instead of just see'ing the iso/bin file, so that i can then check the data inside the iso to see if the file exists etc.Im a novice still at coding so making a new class myself to look inside the iso/bin is to complex for me.

i have a DataGridView responsible for showing a bit of data and two of my columns allow for user input using comboboxes.The trouble is that one column only needs to show preset values in it's list, but the other needs to both show the presets and allow for the user to enter in their own values.i accomplish this by showing the editing control for the combobox with this bit of code:
Private Sub DGV_EditingControlShowing(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) Handles DGV.EditingControlShowing
