I am creating a VB.NET application that will use a FoxPro database as it's main datasource.The problem I've got is that I can browse existing databases and pull out data with no problems at all but as soon as I try and create my own database I get an error message saying "One or more errors occurred during processing of command."

DataGridView Not Updating Foxpro Database?

Feb 19, 2011

I'm using VB.NET 2008 with a DataGridView and I'm interfacing to a Visual Foxpro 6 database using the vfpoledb.1 driver. When I change a value in the description field, it changes in the DataGridView but the database never gets updated. Do I need to use code to force the changes to take place?Here's the code I'm using:

Imports System.Data.OleDb

.net - Excluding Deleted Records From Returned Set Using VFPOLEDB Provider For FOXPRO Database?

May 23, 2012

VS 2010, VB.NET, WINFORMS. In my app i have a need to import foxpro database tables and exclude the deleted records. The problem is that FOXPRO tables keep deleted items inside the same table. I have tried using DELETED=NO in the connection string but vb throws "Format of the initialization string does not conform to the OLE DB specification."

My function is as follows:

Dim _DBConn1 As String = "provider=vfpoledb.1; Data Source = " & file1 & ";DELETED=NO"
Dim _DBConn2 As String = "provider=vfpoledb.1; Data Source = " & file2 & ";DELETED=NO"
Dim _DBConn3 As String = "provider=vfpoledb.1; Data Source = " & file3 & ";DELETED=NO"

Google results pointed me in the direction of DELETED=NO but its throwing that exception error now that I have added it..

Timeout Using SQLite - Create A Database And Several Tables - To Populate The Tables With Data From Arrays

Jul 25, 2012

I am using VS2008 and SQLite. I have created a database and several tables and am attempting to populate the tables with data from arrays.

The following code (example) works fine but stops after it inserts 30 to 50 records. I am running the VB code in debug mode and when it stops, I press pause to see where it is. It stops on "SQLcommand.ExecuteNonQuery()" and when I press continue (F5) it will insert another 30 to 50 records.

I do not get an error message. Is this a timeout issue? How do I keep the loop running to the end of the array?

Following is example code.

VS 2008 - Connecting To Database And Tables With Sentences

Aug 3, 2010

I have a problem using my database in which I have a table with product names, codes, prices and information. I use the below method to get connected to my database and tables.

Dim dtCOP As New AmetailorDataSet.COPDataTable
Dim adapterCOP As New AmetailorDataSetTableAdapters.COPTableAdapter
adapterCOP.Fill(dtCOP)

But in one row, I have product descriptions so there should be sentences. I set the type of this row is Text in the database. When I use single numbers in the table, there is no problem. But if I write sentences (that is a must because it is product description) or even a single word, I get the below error on adapterCOP.Fill(dtCOP):

"Input string was not in a correct format.Couldn't store <(the written text in description)> in Description Column. Expected type is Decimal."

There is a richtextbox in my form that should show the product description when the product code is selected from a listbox available in my form.

VS 2008 - Sqlserver Database - Tables And Stuff Just Vanish ?

Jul 1, 2009

I seem to have a major problem. when I add a typed dataset to my project and go back to my sql server and click on the databse I use it doesn't open. the tables and stuff just vanish. using the wizard, it creates this connectionstring:

<add name="Schenectady.My.MySettings.SISQL2ConnectionString"
connectionString="Data Source=.SQLEXPRESS;AttachDbFilename="C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataSISQL3.mdf";Integrated Security=True;Connect Timeout=30;User Instance=True"
providerName="System.Data.SqlClient" />
</connectionStrings>

It connects fine. but after I try opening it in sql server i get an error. It doesnt let me restore or anything. i tried restarting my pc incase the db was locked but it is still gone. now my app cant connect. Just for clarity, is user instance supposed to be set to true. and what is the purpose of it. also when the wizard asks to make a copy of the file that will be copied accross each time I run my project I select No.

VS 2008 Class To Create Database And Tables From XML File

Jun 27, 2011

I need some expert help in achieving this task. I have an xml file which will be emailed to me everyday. I need to loop through the xml and create tables in a database based on the xml nodes and their attributes. looking at the following xml fragment for example: Code:

So based on the above xml, I would have to create a Shipment table as a Parent with fields like ShipmentIdentifier. Then I would have to create an Event table with the ShipmentID as a foreign key and fields like Source, Code. Basically a field for each node. Then if there are columns in the table that are new, I would have to modify the table and add the column. I only have to create tables where there are child nodes or where the nodes have attributes.

VS 2008 Multi Language Application - Two Tables In Database

Jul 10, 2009

I'm building a multi language application, but in the application, there will be some data that will be retrieved from the db. In the db I have two tables (Access Groups, Teams) the two tables are related, there are some groups, that have teams, example (sellers can belong to team 1, team 2, team 3...). The data that will change it's the names for the access groups and the names for the teams. The only way that I can think to do this, is to have the different values for all the languages in the code, or some auxiliar file, and when loading the application I'll truncate the two tables and fill them with the current language values. By the way those values never change...

DB/Reporting :: Query On Related Tables?

Nov 15, 2008

I have a simple "two-tables" database (SQL EXpress) and a very simple application (VB 2008 Express). The two tables are customer and order and their structures are:

customer(IDcustomer, LastName, FirstName) IDcustomer=primary key orders(IDord, Number, Description, IDcust)
IDord=primary key the tables are related (IDcustomer-->ID cust)

In VB2008 environment I create a dataset, by means of Data Source Configuration Wizard, which encompass both customer and order tables (xsd file). By opening xsd file I set the relationship in the following manner:

"Both relation and foreign key constraint"
Update Rule = Cascade
Delete Rule = Cascade

In my form I show customer table in detail-mode and orders table in datagridview-mode. Two Fill method are created in the Load event and they work correctly.In "CustomerTableAdapter" I create, with QueryBuilder, a search query (say LastName query) and I write the following code:

Private Sub frmSearch_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.CustomerTableAdapter.FillByLastName(Me.CustomerOrdersDataSet.custom er, "D") 'All Lastnames with first letter = D

DB/Reporting :: Update 8 Tables In A Transaction?

Apr 25, 2011

I have an application which upon a save button needs to save data to 8 different tables. 7 of those tables will have multiple new records added to them, while 1 will have just one new record. I want to encapsulate this giant Insert operation in a Transaction so that it will not complete unless I can save successfully to all tables.I have considered using Insert commands to a command statement, but adding what amounts to like 50 parameters, and the fact that using a parameterized query means it becomes very difficult to troubleshoot problems such as invalid values in the SQL statement (since I cannot figure out what the statement looks like with values in it

DB/Reporting :: VBE 2008 Programmatically Use Database?

Nov 5, 2008

I'm using VBE 2008, with .NET 3.5 SP1, and I am trying to programmatically manage a database. Here are the steps I used so far:

1. Project >> Add New >> Local Database >> Cancel Button.
2. Added a table (Files) with three fields (File Path, File Name, and File Type).
3. Went into Data Sources, did Add New Data Source and followed the wizard to add it as a dataset.

I'm not entirely sure where to go from here. I'd like to be able to use queries on this thing, but I don't want to have to use SQL to add to it and such. I've made a little headway in the code, but it's really frustrating because VBA Access was SOOOO much easier to do this kind of thing in. This is what I have for code:

DB/Reporting :: How To Create/update Tables Programmatically

Nov 10, 2008

A suite of apps will be using various tables out of the same sql server database.Regardless of which app is being used, the database structure must stay current. (ie:contain all the tables/fields to run any/all of the apps)So, when the user starts any of the apps, it needs to check the database, for the existence of all the tables and fields it needs, then update if necessary.

DB/Reporting :: Optimize Query (aggregates On Multiple Tables)?

Feb 20, 2008

Code:

Tables:
- Company
- Department
- Employee
- CertificationA
- CertificationB

I am trying to return a recordset that gives some summary information about each company. The fields in my returned recordset should look like the following.

Company.Name, NumberOfDepartments, NumberOfEmployees, NumberOfCertificationA, NumberOfCertificationACompleted, NumberOfCertificationB, NumberOfCertificationBCompleted

There are actually about 10 different Certification tables but, with Certification A and B you should get the hang of it. When an employee starts a certifaction, a record is added to the that certification table.Below is a query I wrote that works (gets me the data I need), but I am unsure if it is the most efficient way. There will be quite a lot of data so performance is an issue.

Code:

Dim sqlNumberOfDepartments As String
sqlNumberOfDepartments = _

"FROM DEPARTMENT " & _

Add A Remote SQLServer Database To My Database Explorer Window In 2010 Express?

Feb 14, 2011

I'm trying to use LINQ to SQL in Visual Basic 2010 Express.

It allows me to create the .dbml file, but in order to drag items from the Database Explorer window to the design surface, I first have to get my database listed in the Database Explorer!(this is a remote SQL Server database - not a local .mdf)

I already have a good, working connection string to the remote SQL Server database, but that doesn't help me when I'm trying to generate the DBML at design time.

Can anyone tell me how to get my remote SQL Server database identified in the Database Explorere window? When I try the "Add Connection", I am limited to Access, SQL Server Compact, or SQL Server Database File. If I try to enter the IP address & port of my DB Host I get a 'database file does not exist' message. Doesn't seem to want to let me point to a remote DB server...
