Excel Dataset - Preview In DataGrid And Save To SQL Table
Mar 25, 2009
I am creating an app to grab data from excel and preview in datagrid. From the datagrid I want to be able to save to a sql table. I have the excel data in a gridview via a dataset. What I am having trouble with is the sql statement. I know how to insert data, but I can't work out how seperate the data in the dataset to pass it into individual Values of the insert statement. Or should it be done another way? NOTE: I is not essential that the excel data be previewed in the gridview if this would make life easier for me.
Here is my code so far:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'Grabs data from excel sheet and stores it in datagrid.
Dim ds As New DataSet
Dim da As OleDb.OleDbDataAdapter
Dim con As New OleDb.OleDbConnection
[Code] .....

I have three tables, the extremely simplified versions of which are:
Practitioners:
practitioner_id :: int
name :: nvarchar
Insurances:
insurance_id :: int
name :: nvarchar
InsuranceLink:
practitioner_id :: int
insurance_id :: int
So, the practitioner table contains a list of practitioners, the insurance table contains a list of insurances, and the link table represents which practitioner supports which insurance. Now, I need to create a view which can display the information like this:
ViewTable:
practitioner_id :: int
practitioner_name :: nvarchar
insurance_1 :: bit
insurance_2 :: bit
.....
insurance_100 :: bit
In other words, the columns in the view are the ID and name of the practitioner, and every insurance that exists in Insurances (with the insurance name as the column name (there is an enforced condition that insurance names are unique)). The cells in the insurance columns will indicate if that practitioner supports that insurance. Or better yet, is it possible to use an excel-style pivot table on a DataSet in a VB.NET form?

I'm creating a tool that will query Excel and intialize the default settings for the site's Cad Software.I want 2-20 users to be able to simultaneously query excel. Currently I have the spreadsheet open on one computer and the other test machine gives me this error.
GetOleDbSchema Table Require an open and available connection. The connections state is closed.
I could use some help on the code design. Should I use Datareader instead....Does that have less permissions issues? Or do I need to open up the oledbconnection in a different manner?
Private Const cPageData = "PageData"
Private Const cPrinterData = "PrinterData"
Private Const cSupportData = "SupportData"

I'm using the 2008 express edition. Now, I created an application that will allow the user to choose transaction in the combobox.text and input its price and quantity using an textbox.text. When the user click button1, it will be push in the datagrid/datable I created. And when the user click the button2, it must be save to excel file. The only thing I need is how to save the data from datagrid/datatable to excel. This is my code.

Imports System.Data.SqlClient

I am attempting to write the entire contents of an ADO.NET DataSet to an Excel 2007 spreadsheet and, while having partial success, I am unable to dump the contents of the DataSet into the .xlsx file. "Partial success" meaning that I can generate the spreadsheet(s) ok, but cannot get the DataAdapter.Update to work.

My query is i want to save record from an excel sheet to my Database Table.
But i dont want to insert the Excel sheet as a whole rather i want to insert the record in my database table Row wise.Inserting the records is not the only thing but my major issue is i want to check and compare the Primary Key column of my Table with the Column in my Excel.
Suppose Table1 is my Sql Database Table,and RegistrationNo is the Primary Key Column.Similarly there is also a column of Registration Number in my Excel Sheet.
Now before inserting each record the RegistrationNo column should be compared.If the a registrationNo in the excel sheet say RegistrationNo 112 is already present in the table then it should not Insert the record and if its not present then it should insert.
Also the other issue is the number of columns in my Database table are more than the number of columns in my excel Sheet.So the columns that are not present in the excel sheet should be set to NULL while inserting the record in the Table.

My company is making thousands of products now, every one of them have several test report in excel files. I am thinking about putting all of them into a microsoft sql database,
1. Is it wise to do so? I think a sql database is a lot easier to manage.
2. Can I save or convert the excel file as one data in a table? How could I do it? I only see a image type for data type. Surely I expect to retrieve the excel file through ASP.Net website if necessary.oh, some additional info, every excel file is not big, but it contains pictures inside sometimes.

I'm working in VS 2008, vb.net. I have a data grid that is getting filled based on a store procedure. When I preview the datagrid, I will get 29 rows back. This includes rows that have NULL values in it. And that's what I need. But when I run the program, it will only return in the Datagrid 12 rows, the rows that don'r have any NULL values. Where or how can I change it so the DataGrid will show NULL values?

On the left half of my screen I have a datagridview. On the right half I have a document preview pane.As I change rows on the left half, I use the CurrentCellChanged event to open the document associated to that row in the previewer.This works fine, however, the focus is then placed in the preview pane which prevents the user from being able to use the arrow keys to step down a row at a time.To combat this, I made the final event in my CurrentCellChanged routine set the focus back to my datagridview. Unfortunately, even this doesn't always work because of what seems to be a timing issue.If the document to be previewed takes more than a fraction of a second to open, the code to move the focus to the datagridview is executed but after the image completes drawing, the focus is moved back to my previewer.I don't want to use a timer to force a delay and a DoEvents causes me some other issues.Is there some other event I can use to determine when my preview pane is complete and then and only then set the focus back to my datagrid?

I was wondering if anyone already done this. And off course How?I'm working on a project to get several departments incoorperating the same budgetting systematic. Yeah hell is pretty near so far.
What I need is a way to create a preview in excell for the template they are defining in an application. As the end user will enter the data in an Excel sheet... YES this IS mandatory in this phase.
So I want the department manager to drag items into a treeview defining a template and generate a excel workbook and show a sheet with the result of his definitions.
Question? how can I show an Excel sheet within a vb.net application?

I can't get this to work. My program fills all the values into an Excel spreadsheet- no problems there. What I'd like to do is a print preview/print function. I can't seem to get my code right, all I get are blank pages in the print preview box.
Dim oExcel As Object = CreateObject("Excel.Application")
oExcel.Workbooks.Open("C:DailyLogsDailyLog.xlsx")
PrintPreviewDialog1.Document = PrintDocument1
PrintPreviewDialog1.ShowDialog()
oExcel.Sheet1.PrintPreview()
So as I see it, this should open excel, then navigate to the actual excel file. The print preview dialog should come up, which it does, and the excel sheet1 should be previewing, but it's not? I don't have any errors, just a blank print preview. At least thats how I see it, but obviously I'm wrong because it won't work.

I need to be able to test if the current view is print preview in Excel 2003.
Is there something in the excel object model to simply access this property? (Like the application.printpreview in the Word object model...).
PS: Long story short, I'm developing a vsto addin with keyboard short-cuts to my custom functions, and I need to disable this shortcuts when print preview is on.

What I am trying to do basically is open an access query in a datagrid view and then be able to make changes to the datagrid and then save it back to the database.When I try to save:
Me.BindingSource.EndEdit()
Me.TableAdapter.Update(DataSet)
It says that update is not a member of the tableadapter... Why is that?
