VS 2010 - Filling DataGrid Columns With Excel Data
Mar 26, 2012I finally got this code to work:
vb
Dim path As String = OpenFileDialog1.FileName
Dim myDataset As New DataSet()
Dim strConn = New OleDbConnection("Provider=Microsoft.ACE.Oledb.12.0;Data Source=" & path & ";Extended Properties=""Excel 12.0;HDR=YES;IMEX=1""")
Dim myData As New OleDb.OleDbDataAdapter("SELECT * FROM [Sheet1$]", strConn)
myData.Fill(myDataset)
DataGridView1.DataSource = myDataset.Tables(0).DefaultView
Now that I figured that out I was going to try and place the data in a specific location. On my application I have a datagridview set up with 4 columns. What I would like to do is put column A of the excel file under the 1st column of the datagridview and column C of the Excel File in the second column of the datagridview.
So replace:
vb
DataGridView1.DataSource = myDataset.Tables(0).DefaultView
With:
vb
DataGridView1.columns(0) = myDataset.Tables(0).columns(0)
DataGridView1.columns(1) = myDataset.Tables(0).columns(2)
Obviously this doesnt work, and something tells me I might need a for loop to import the data, but I have never imported information from an Excel file before and to make it worse I have never worked with datagridviews before so I have no idea how to go about this.
I would like to do something like this if I could:
vb
For x = 1 To xldoc.rows.length - 1
DataGridView1.Item(0, x).Value = CType(xlDoc.Cells(0, x + 1), Excel.Range).Text

Forms :: Reading DataGrid From External Program?
Aug 29, 2011I am working in windows forms with Vb.NET 2008. I am trying to read text in from an external program. So far I have been able to read text in from a standard text box or button, however I am trying to read data in from an external data grid.
When I try to use the following I get no information about the grid
ChildHandle = FindWindowEx(ParentHandle, IntPtr.Zero, "classnameofexternaldatagrid", Nothing)
Dim Hndl As IntPtr = Marshal.AllocHGlobal(2000)
NumText = SendMessage(ChildHandle, WM_GETTEXT, 2000, Hndl)
Text = Marshal.PtrToStringUni(Hndl)
Usually if it is a standard text box I will get the text data with no problem, but it is a standard data grid and there are no further sub handles to try and read from. If WM_GETTEXT wont read information from an external data grid then how would I read in the data?

Generate Next Available Code In A Datagrid
Nov 13, 2011I have a materials library that I am adding into a database, the library has a number of columns, the one I am concerened with here is the Item Code column.
All Item codes start with 'M' and then have an integer after them (M1, M2, M3.....M9999 etc) What I want to do is to auto generate the next available item code when a new line is added.
The next available code should be based on the last value in the 'Item Code' Datagrid View column but I don't know how to do this.
I have tried getting the next available code from the database but this doesnt work as I want it to.
