Tables Relationship - Connecting With Each Other?
Mar 15, 2012How would I connect different tables with each other in vbnet2008 which ive connected by the database wizard? Also I want to connect this table for the search purpose. I filter it by Name which is in my personal_informationtbl so the rest of the table must show the related information about the Name that I've searched. So meaning if I just search by name it shows related information from the records not just from the personal_informationtbl but fill the other tables with the related information.

View 3 RepliesVS 2008 - Connecting To Database And Tables With Sentences
Aug 3, 2010I 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.

Quote:

View 2 RepliesError Connecting To Analysis Servives From Asp.net App On Another Machine?
May 8, 2009I have been tasked with getting a asp.net (vb.net) talking to an analysis services engine on our production servers. The web server is a separate machine from the web server.The web server runs as the IUSR_ user.The application (of course) works on the development machine which has both IIS and Analysis services on it.The problem I see appears to be a permissions error (returned in the browser by the asp.net app):An existing connection was forcibly closed by the remote host ....
it is described in a similar post here: http:[url]......I am not a system admin, nor am I an expert in analysis services (why have I been tasked with this you ask? because other people haven't been able to get it working and it has fallen on me). I have tried creating and adding the user (IUSR_) to the sql server and added that user to the role. While that worked on my local machine, it did not work in our production environment where the sql and web servers are separate.
Error Connecting To Citrix Database Via SQL-specified ODBC
Sep 23, 2010I am connecting to Citrix database using SQL-defined ODBC. Having a problem with it. I am updating an existing application that uses the ODBC in SQL, and it connects fine. However, that database connection is secured, only available on the production side. The test side has a remote connection. I am attempting to change the remote connection values to match the parameters of the SQL-based ODBC, but the labels are different, and it doesn't seem to match. Specifically, I don't think I'm getting the DataSource correct. Also, it can't find the username and password that I use to log into the remoter connection - I get an error message "Invalid authorization specification".

Get An Error Because The Sqlcommandbuilder Does Not Generate Statements In Multiple Tables?
Jan 26, 2012I have 2 tables in MySQL database. These table were joined through a query and handled by a dataset. Im displaying these data through setting the dataset as the datasource of my datagridview. But when it comes to Update, Insert and Delete statements, I got an error because the sqlcommandbuilder does not generate statements in multiple tables.I want is, when I press the update button..all the changes made in the datagridview will be updated in the database. Can i make it without creating a datasource in design mode or through smart tag? If I have to manually create an UpdateCommand for adapters..Can I have a code snippet for that?
View 1 RepliesIntermittent Access Database Error (Linked Tables)
Apr 14, 2011I have a system that gathers raw data from electronic devices, uses that data to populate a set of tables and allow uses to add/edit certain data and report on it. (Kind of basic right...NOT) There are 3 applications that I've written that use the same database.
One is a client that is on 3-4 user machines which allows them to see the data that has come in and work with it.
Two a Data-to-Information process program which takes the raw data, checks up certain information and puts the results into the database.
Third is a data gathering app that interfaces directly with the electronic devices and about 10 times per day places the raw data into a single table in the database.
If a user is in the 'client' application the data processing application crashes all over the place:
1. Database file already in use.
2. Unrecognised Database format
3. File locked exclusively by User on PC X.
Almost always on a different line of code and once when I made it retry over and over I managed to corrupt the database and had to Compact and Repair it to fix it. If no one is using the client everything works perfectly. On each client machine is a database with linked tables to the server machine. The machine that is running the Data processing is the server and the processing is using a database in a different folder that also has linked tables.
I have gone through all the recordsets in the Data Processing application and made sure that they are only using ForwardOnly and Read Only. They edit the data only with Insert, Update or Delete queries. I'm about to do the same in the Client Application as it seems to be the one that is locking everything all the time. The client machines haven't crashed on that error at all. Does it matter which version of Access is on the client and server machines? (All the clients have Access 2003 and the server has 2007 but the Database was created in 2003). Should I just convert the Access database to SQL server and be done with it?
