Importing Csv To Mdb File - Multiple Fields
Feb 11, 2010
I had this code working to import one column in a table as a starter point, but now that i'm trying to import all the columns in the table, i'm running into problems.
When I run the app, I get this Microsoft . NET Framework error:
Syntax error in INSERT INTO statement
I've tried just about every combination I can think of for the sql statement and still the same error message.
Imports System.IO
Imports System.Data.OleDb

I have a text file in this format

[CODE]...
Basically I would like to read in this file line by line and separate every every field into a custom variable and then do some processing. So, I would read in the first record and put the data into these fields
date
time
ticker
sector
open
high
ETC
I started coding this using a TEST file that only had two fields name and a number
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'Dim FILE_NAME As String = "C:aaple2.txt"

I got an unhandled exception on this line: mNum = objReader.ReadLine

I tried searching for a solution, but couldn't find anything, so if I am re-asking a common question, don't beat me too badly. For a class, I have to create a form that allows someone to enter in the names of six students, as well as five test scores each. It also averages the scores, and displays them in a label.
What I am wondering is if there is a way to clear the text from all 36 text fields, as well as the 6 labels without having to do everything individually?
I could certainly go through, and write out txtField1.text = String.Empty 36 times, but it seems there would be a more elegant solution. Also, if there is a way to do so, would the same would apply for putting the data entered into an array, or saving it to a file?

The below sub-procedure isn't working like I expect it to. Basically, I have 9 fields on a tab control. When a user clicks in one of the fields, I wish for the field to "SelectAll" if their is a value already in the field. As you can see, the way I have it structured...only 1 field will do this, however, even this is not working.
Private Sub txtAddr1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtAddr1.Click, txtAddr2.Click, _
txtAddr3.Click, txtCity.Click, _
cmbState.Click, txtZip.Click, _

is there a way i can get my datatable to have multiple constraints that are attached to a unique id? an example of what i'm talking about is if i have a unique machine but it's on many lines, can i show that somehow in a datatable? the reason i'm asking is that i have code that sorts the data by line number and shows the relevant machines in a combo box based on the line selection out of another combo box. i'm having to input the data into the datatable (as a starting point for the data base) and it's very tedious. i'm entering machines that have the same name in multiple rows because the line number is different. i can't figure out how i can add multliple values into my line number column so that it will sort properly when queried.an example of what i'm asking with regard to the datatable is as follows:
Machine LineNumber
slicer Line 1, Line 2, Line 4
conveyor belt Line 1, Line 6
So that when called to fill the combo box, the correct one is called.The code i'm using to sort right now is as follows:
Private Sub linecbo_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles linecbo.SelectedIndexChanged
Dim cline As String

VB.NET 2008 windows app form.I have a groupbox with several checkboxes, comboboxes, and textboxes within it.With the help of StackOverFlow members, I've learned how to use the FOR/NEXT loop to find all checkboxes that are checked.[code]As you can see by the code sb.tostring will print every checked checkbox name on its own line.How do I associate the proper combobox.selecteditem, textbox.value, and checkbox name to print out on the same line.When I say proper...example; checkbox=pen, combobox=color, textbox=quantity.Let's say my other checkboxes are different items and the rest of the boxes are the same.

My LINQ query contains the following Group By statement:
Group p By Key = New With { _
.Latitude = p.Address.GeoLocations.FirstOrDefault(Function(g) New String() {"ADDRESS", "POINT"}.Contains(g.Granularity)).Latitude, _
.Longitude = p.Address.GeoLocations.FirstOrDefault(Function(g) New String() {"ADDRESS", "POINT"}.Contains(g.Granularity)).Longitude}
The query works, but here is the SQL that the clause above produces
SELECT [t6].[Latitude]
FROM (
SELECT TOP (1) [t5].[Latitude]
[Code]....
but this produced an error: "A group by expression can only contain non-constant scalars that are comparable by the server."

I'm looking for a way to combine a field from multiple tables into a single field in a new table. Because the data populating the tables is coming from an outside source, I would prefer not to change the data in the original files. I have a separate table for each year because this is the way the data is provided. The field layout is not consistent from year to year, but each year there is a field that we'll call "score." I'd like to pull the field "score" from each year's table and have it populate a "score" column in a new table along with the year of the data so that all the years' scores are in the same place. Is there a way to do this using Visual Basic + Access?

I have tested my code in order to pass single value to single parameter field in crystal report from VB.NET Form, it is ok but the problem is that I want to pass multiple values to only one parameter field called "Product Name" and it displays only one last record.
I want to display like this
Receipt : 0001 Product Name
pencil
pen
stamp
book
[Code]....
I already set parameter field "productname" for allowing to multiple values, but it is still the same.

Is this possible? I upgraded to VB Express 8 and have several programs that I would like to import into VB Express 8 from VBE 5. But everything I have tried so far has not worked.....This is the first time I have imported files from one computer to another. I have tried to save the file as a zip file and unzipping it in VB 8, but that didn't seem to work.

I am trying to create a form which will be fed by an underlying database to create multiple form fields for each entry in an underlying database table. This is for a program to monitor patients under anesthesia, and prior to surgery, the doctor will choose which monitors they will be using. Then, on the actual monitor screen which will pop up every X minutes, there will be a text box and a check box for each chosen monitor. I am relatively new to VB, so I have tried to illustrate what I am needing but using the logic that I know from my previous life in PHP.
I am using DevExpress's layout control to place the form fields, so that is the code in the middle of the first loop (on_load), and I know that part works, I just need to know how to name the fields and then recover those fields and commit the values to the database. (the text boxes are added to the database, the check boxes are used to determine if an entry is made for that monitor- i.e. at the end of surgery if a monitor is turned off). I know that my syntax for naming the fields is no where close to correct, and it probably would not work in PHP, but I remember doing something like this in a PHP application I built long ago. [Code]

I have a datagridview on my form with 7 columns and a variable number of rows. It's used to track stats on games (kills, deaths, assists, etc.) The way I ended up saving it was in a .xls file for the simplicity of being able to edit it in excel as well as my program. how to import the file back into the DataGridView though.
Here's the code I'm using the save the file:
VB.NET
Private Sub exportExcel(ByVal grdView As DataGridView, ByVal fileName As String, _
ByVal fileExtension As String, ByVal filePath As String)
' Choose the path, name, and extension for the Excel file

I have been able to load up the file, in to one txt box, but am unable to separate the items in to their own box. Should I be using arrays for this?

I have inherited a VB.net web app that I'm making some changes on. I'm perfectly capable with the programming side (VB and MSSQL) but I'm getting lost with the tools. I was given a zip file of the code and everything. I opened the sln file in Visual Studio 2005 and it worked fairly easily with little modification.
Running the app works perfectly. Problem is, I need to write some new SPs so need the database admin. SQL Server 2008 Express is installed but it doesn't see any database and I have no idea how to import it.I have a folder App_Data in the project with the file ASPNETDB.MDF. Opening this in VS gived the error: This server version is not supported. You must have Microsoft SQL Server 2005 Beta 2 or later.

Im having strange problems when importing data from an excel file into a sql table. Everything seems to imports ok until i look at the data in more detail, this is when I notice its imported the data but in the wrong order. for some reason when I look at the db table all records are in the wrong order, and strangely enough it seems to be a different order every time I import things. Is there a way to force the routine to import the data in the same order as the it is in the excel file?, because at the minute it seems to have a mind of its own.
My code is below:
Public Function ReadExcelFile(ByVal sFileName As String) As Boolean
Dim oSQL As New clsSQLHolder
Dim excelCon As String
[CODE]........................
