VS2008 - Function Starts When Click Any Cell In Spreadsheet?
Dec 2, 2009
My application involves a spreadsheet on a VB form. I installed the COM add-in for the spreadsheet okay, and I see it in my form.Now, I need the following feature: When the user clicks any cell on the spreadsheet, a defined function will run. This is for scheduling events in a calendar. The user can click on a cell in the spreadsheet, the function will evaluate the text string in the cell, then decide what to do, based on the text.

i have a button in my application that starts a function to play sounds.But when the function starts a have a problem that my application stops working until all the sounds are played. Then a want to display a waiting screen to show the status of the current application. To this i thought to create a new thread to open the waiting window and then show the messages.
But i have a problem that when my thread finishes, it closes the waiting screen. I tryied to put a loop inside my thread, but this crashes my aplication until the loop condition is satisfied.

How can you add a image where when you double click on the icon and the program starts it shows a picture before the program loads. Like Photoshop startup or the new 2010 visual Basic express start up

I have a VB.Net program that reads in a flat file, and then parses line by line, formatting the data into different spreadsheets in an excel workbook (each line can be any 10+ different record types so I parse and put in appropriate excel sheet).
For smaller sized flat files (under 10mb), the parser works great. However, I am trying this on a file that is over 120mb (400k+ lines). While running, I will get an OleDBException saying that the spreadsheet is full. Now I am pretty confident that Excel can handle a much larger data set than a flat file. So I assume this exception is not giving me the true story as to what is really occuring.
I open a connection, and then parse each line in the file, inserting each row into the excel file. I assumed it would be bad performance wise to open/close the connection between each insert. Could this be causing the issue? Any ideas what I need to do to handle such a large file? There are cases where the flat file can be over 500mb.
To actually do the insert into excel, I am just doing the following (I construct an sql query based on the type of row and values parsed):
Dim conn As New OleDbConnection()
conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + ExportLocation.Text + "" + importFileName + "-PVF.xls;Extended Properties=""Excel 8.0;HDR=YES"""

I am wondering how you would go about making a search function for a grid in VB.net. Right now, I have it so that the person clicks a button and they see the last 50 records they've looked up. This works fine. I also have a search button that works like this[code]...

I have a problem with Data Grid. I'm calling my function in dataGrid.cell_endEdit and it doesn't work exactly the way I want it to. If I'm editing a cell and click in menu (or press ctr +s which means Save cell in my program), cell_EndEdit is not running. I know it is correct, but what can i do to save my changes in these cases?

I have a datagrid. Its 1st column is ClientType. On clicking each cell in the first column i.e ClientType, that value is shown in textbox named txtClientType. For that I used the following code.
Private Sub dtGridsearch_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DataGridItemEventArgs) Handles dtGridsearch.ItemDataBound
Dim lt As ListItemType = e.Item.ItemType
If lt = ListItemType.Item Or lt = ListItemType.AlternatingItem Then
Dim currentCell As TableCell = CType(e.Item.Controls(0), TableCell)
[Code]...
The above codes work in IE. But in Chrome when I click a cell in datagrid the corresponding value does not show in the textbox. I am using VS2008. What could be the reason?

I have a button on a datagridview (dgproducts)that when clicked, sends the data from that row to another datagridview called (DgSelectedProducts) in a Keypress. The button on dgproducts is unbound and is (0) and is named AddProductsButton in the collection. I am using a barcode scanner into txtboxsearchbarcodeID so that when the user enters the barcode to the textbox it finds the barcode in the dgproducts it filters down to that item.
When I say filter I mean all the items that do not match are not shown on the dgproducts datagridview. Only a single item can match. That part works ok. The problem that I am having is that I do not know how to perform a click on the cell(0) ie addproductsbutton so that the item is passed from the dgproducts to the dgselectedproducts when the item is scanned. This is for a POS form so it needs to do this.
Private Sub txtBarcodeSearch_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtBarcodeSearch.KeyPress
' If e.Handled = Keys.Enter Then
txtSearchTerm.Text = txtBarcodeSearch.Text
Me.CBOProducts.DisplayMember = "ProductIDBarcode"
cmbSearchField.Text = "ProductIDBarcode"

I am trying to create a function that will take a fixed value, and increment another cell. It does this until another cell using a formula equals the fixed value. You can see what I have below, but this is my first VBA programming ever so I dont know exactly how to declare everything.
Function meetMargin(Margin, calcM, nrc)
Dim x0 As Double, x1 As Double, x2 As Double, t1 As Double
t1 = 0.05
Do While t1 >= 0.01
x0 = Range("Margin").Value
x1 = Range("calcM").Value

Is it possible to change the background color of a cell when I click on it?
Also, is it possible to set a property so that when a cell is clicked on once it already has the focus that the 'edit' text feature doesn't let the user to change the text?

I am creating an application for a college assignment called "Quote Manager" - the idea is a writer can save his / her favourite quotes, then go back to them and be able to print them.So I had this idea where all the quotes are loaded into a datagrid view on the main screen of the program and the user can double click on the quote he / she wants to load.
I don't want any code given I would also post what I have got so far but at the moment I am at work.What I want is to know how to manipultate the datagridview control so when a cell is double clicked a saved html page will load from a database.

What im trying to do is, when I click on any row on my datagrid(dgvCompositions), all the cells(16 columns excluding ID column) in that row must be loaded into the 16 textboxes I have (txtB1, txtB2, txtB3....)
So when I click the row, and the entire row is highlighted the text from the cells get loaded into the textboxes.
I know how to pull data or text from specific cells clicked
Private Sub DataGridView1_CellClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellClick
TextBox1.Text = DataGridView1.Item(0, e.RowIndex).Value
End Sub
But the problem I have is that how do I pull all 16 simultaneously and put them into 16 individual text boxes?
