Load Data From Excel And Calling By Columns As Fieldname?

Apr 21, 2009

I am having a problem regarding to Importing file from excel to listview. Actually my problem is that my program will let the user define what database he/she want. I know already how to load on my listview from .txt, access, ms sqlserver, but my problem is the user want to open from excel file. Base from his data, the columns contained Contact, address, age,name and only in sheet1. My problem now is that the user want to call his/her excel act like a database. The tablename will be Sheet1 and if he/she want to display the age and name column he/she can view by calling the its columnname. The columname will act as a fieldname. How can I do this upon loading all of this to listview. I have here an example on how i load data from .txt(csv) format but i need an excel on how to load data coming from excel.[code]...

Data Query From MySQL Bracket In Fieldname Causing Havoc

Mar 12, 2009

I am trying to write a query on an .aspx webpage connected to an .aspx.vb file to access some parts information on my mysql server. Everything works fine except for one poorly named file, which keeps breaking the query. The fields name (with the table name in front) is
invf12.PRICEE(1STU_M)
Those brackets seem to be the problem. I have tried putting single quotes around them, as in
invf12.' PRICEE(1STU_M)',

I can't do anything about the fieldname. The query in total looks like this:
Protected Sub LookupPart_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles LookupPart.Click
Dim strSQL As String = "SELECT invf12.ITEMCODE as Part, invf02.DESCRIPTION as Description, " + _
"SUM(invf12.QUANTITYONHAND - invf12.QUANTITYRESERVED) as Available, invf12.PRICEE(1STU_M) as Price" + vbCrLf + _
"FROM invf12, invf02" + vbCrLf + _

Load The Data From Database Into A Datagridview With One Of The Columns Being A Comboboxcolumn?

Jul 27, 2010

easy way to simply load the data from database into a datagridview with one of the columns being a comboboxcolumn. Apparently there is no selectedvalue, selectedindex or value as in a combobox to return the combobox value. What I need is to verify if the database value is 'true' and if it is then I need to set the comboboxcolumn with a specific value.

Ex:

if ds.tables(0).rows(0)("flag") = "true" then
datagridcolumn.selectedvalue = 1
else
datagridcolumn.selectedvalue = 0
end if

VS 2010 - Filling DataGrid Columns With Excel Data

Mar 26, 2012

I 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
Next

Reading Excel Into DataGridView And Typing The Data Columns VB 2010?

Sep 5, 2011

In my application I read data (using data binding) from an Excel spreadsheet into a DataGridView. This works, but the data columns contain text fields (strings). I would like to set the data type for some columns to "Date" and Decimal. I cant do this on the DataGridView (error: cant change properties for data-bound stuff) and I cant figure out how to do it on the dataset or data-table that I bind to the DataGridView.The following is the code I use to read and bind the data:

Using con As OleDbConnection = New OleDbConnection(cs)

'open the OleDbConnection

The commented out code (below the 'Todo: comment) causes a additional table, but I want to change the table with the data.

How To Load A Datagridview With Data From Excel (dynamically)

Feb 7, 2010

I was wondering if there is any way to load data from excel sheet into a datagridview in VB2008 dynamically. I have looked at few data connection codes but all of them involve the excel sheet and thw workbook name. Is there anyway that I enter the excel sheet name in a inputbox and the data from excel loads into datagridview without hardcoding the sheet name. I know data can be imported using the below code, here the programmer has to mention the excel workbook name, path and sheet name. [code]I am developing a program to perform some calculations and my data is in a number of excel workbooks and worksheets. I need to be able to bring the data from these excel sheets into the datagridview to perform calculations. So I was thinking if I could mention the excel sheet name in the GUI and then accordingly the data from that particular sheet would be loaded into the datagridview to perform calculations.

Open Excel File, "clean" Data, Load Into Datatable

I'm using VB Microsoft Visual Studio to try to open an excel file, clean a column of data, then load into a datatable for use by program (enter Excel data into Reflections, process / screenscrape, enter data into Access db).

I can load the data into a datatable just fine, but I'm having problems figuring out how to open the excel file BEFORE it's loaded into the datatable so I can "Clean" a column of data the program reads from that can potentially have hidden characters. Below is what I have so far.

Calling Button Click Event On Load?

Jun 1, 2011

While studying sample code for vb.net, I put the code in a button click event and need to click the button to see the results. It would be nice to have this code run by adding Button1_Click() to save time but I get an error because of the parameters needed for the Click event.

I get a suggested "Generate Method Stub for Button click event" which is probably a clue to the problem if I had any idea what that means.

.net - Visual Studio 2008 To 2010 'fieldName' Is Not A Member Of

Sep 8, 2010

I created a new project. I copied files from the original VS 2008 project into the new VS 2010 an used "include" in VS 2010.I get an error saying "Error 108 Maximum number of errors has been exceeded."

It seems that EVERY field in the webformsuser-controlsASCX's has the error message "fieldName' is not a member of".I tried a delete the contents of the ASCX and ASCX.vb for a specific ASCX. Compiled and that page had no errors (although the other pages did). Copied back the contents ASCX and compiled (although the other pages did). That page had no errors. Added back the code-behind in the ASCX.vb and compiled. Same error.'fieldName' is not a member of They fieldName can be anything. Textboxes, hiddens, checkboxes, etc.

what am I doing wrong? I have spent hours on this I am hoping I am just missing something simple.

Calling Up An Excel Spreadsheet?

Jan 22, 2009

if any of you have called up excel spreadsheet data within your VB.net app. Is it at all possible instead of calling up access and the like?

And just before some overzealous person puts "we will not do your work for you blah blah blah......" Im not asking you to write it for me, im just asking if its possible, has anyone succeeded in doing so?

Id rather not use VBA script if possible, Id like to create my own app and use a spreadsheet that has all my workings on already - sorry if its a bit noobie to ask such a daft question but one of my friends is going to be opening a restaurant soon and asked me if i could do a little prog for him using his excel stuff

Re-arranging Columns In Excel?

Sep 26, 2011

Is it possible to take an Excel spreadsheet and move some columns around? Basically I receive spreadsheets that need to be re-formatted and have the columns shifted, some also need to be deleted. I have no idea how to go about this, is it even possible? It's always the same columns so it's not like it changes from file to file. I know it probably makes more sense to just create a macro but I thought I'd see what was involved in it anyway.

Code For Calling Up Microsoft Excel In 2010?

Aug 25, 2010

I am pretty well a novice to Visual Basic 2010 and am trying out the VB2010 express edition. I not the the coding syntax for VB2010 is different from VB6. I'd like well documented code for opening Excel, creating/opening a Workbook, reading and writing data and closing Excel Workbook when I exit the VB2010 form.

I am developing a VB2010 application form which I'd like to work dynamically with an existing MS 2003 Excel spreadsheet that will be provided with the application . The VB2010 form provides some data input for cells in a worksheet (named "Fuels") in an existing Excel Workbook called "carbonfootprinter.xls". Based on the input data, calculations are performed and the corresponding results are output to other cells in the same "Fuels" worksheet. The results are then also graphed in the Excel Workbook. When the application form loads, I'd like VB2010 code that checks if the "carbonfootprinter.xls" exists and is open, if not then it should be opened to receive data input from the VB2010 form and to perform calculations,and finally the VB 2010 application should close the Excel spreadsheet

Delete Excel Columns And Duplicate Values

Jul 5, 2011

I am trying to create a .Net application to edit a excel file by deleting some columns and keeping the columns which we need and then removing the duplicate values based on the first column which is going to be the Serial no. which should have a check to have 6 digits by default like 2563 should be displayed as 002563.

Code:
Public Function GetAllFileContents(ByVal path As String, ByRef errorMessage As String) As IList(Of String)
Dim contents = New List(Of String)
Try
Dim files = Directory.GetFiles(path, "*.xls")
If (files.Length = 0) Then errorMessage = "Please select the files"
For Each file In files
[Code] .....

I am trying to create something different by not only letting me do it for excel files but for say txt and csv files along with it. Removing all the values which I dont want and removing the duplicates and then if possible putting a check on the first column of data that the serial number number should have minimum of 6 characters and then The output file should have all the details in Uppercase

Excel Reading - How To Ignore Hidden Columns

Aug 12, 2009

I am reading XLS files, via JET provider, using the following

cn = New OleDbConnection(conString)
cn.Open()
da = New OleDbDataAdapter("SELECT * FROM [" & sheetname & "]", cn)
da.Fill(dt)

The problem I am facing now is that some of these excel files have hidden columns: These columns are meant to be ignored. However, the code above fills my datatable with ALL columns (hidden and nothidden). Is there any "Extended Property" that I could add to the connection string, to ignore hidden columns?
