Retrieve / Update Data From Remote Database

Jul 22, 2011

I'm currently working on an application written in VB.net using Visual Studio. The app retrieves and updates data from a remote database. While debugging, I updated a particular row in the database and after messing around a bit managed to crash the app. Since then, whenever I fetch that particular row, the data that was previously updated continues to be retreived - regardless of what is actually in the database.

All other rows properly reflect the data in the database and are capable of being updated through the application as they should. However with this one particular row it continues to retrieve outdated data and locks up the application when I attempt to perform an update. Does Visual Studio create some sort of local copy of the database which was perhaps corrupted?

Update Remote Database Via Web Service?

Aug 13, 2011

I am writing a vb.net client application that uses a web service to connect to the remote database.So far I am able to connect to the web service and read, add new and delete data from the database. I am having a hard time updating data.

I have a datagridview control that is bound to a dataset retrieved from the remote database using the web service.When a record is edited in the datagridview control, I need the dataset that is bound to that control to be updated and then that updated dataset to be sent to the webservice to update the remote database.

My client code in the btnUpdate_Click event

dim new_ds as new dataset = datagridview1.datasource
Dim es As New testwebservice.equipmenttracker 'the web service reference
dim msg as string = es.updateequipment(new_ds)
messagebox.show(msg)

Update Dataset Back To Remote Database Via Web Service

Jul 14, 2011

I am connecting to a web service that returns a dataset that I use as a datasource for a windows client datagridview.

Once a user has made changes to the datagridview record(s), how do I get those changes back to the connected dataset and back to the remote database.

I wrote the sql update function in the service:

Code Snippet from web service

<WebMethod()> _
Public Sub Update_equipment_repair(ByVal repair_id As Int64, ByVal date_entered As DateTime, ByVal date_sent_in As DateTime, ByVal date_returned As DateTime, ByVal damage_description As String, ByVal vendor_id As Int64, ByVal repair_description As String)

[Code]....

This displays the records perfectly and I figured out how to delete and insert records via web service.

writing updates from the datagridview back to the database.

IDE :: Failed To Retrieve Data From The Database, Database Vendor Code 9421?

Jan 17, 2011

I have a report made in Crystal Reports XI. The report is generated and exported to PDF in visual basic script using COM interface. Generally everything is running smoothly, but in one case generation breaks with error: Failed to retrieve data from the database. Details: [Database Vendor Code 9421]

Database used is MSSQL 2005 connected over ODBC to CR XI. When I am opening report with exactly the same parameters in Designer, everything works fine.It looks like it is data related, but it is hard to trace since the whole report is pretty sophisticated. Anyway I spent half a day on crawling over Dr. Google and it seems that he has no clue what might be an issue.

Retrieve Data From A Datagridview Loaded With Data From A Linq Database

Apr 9, 2010

I have three tables in SQL server which I would like to show and access on a form. Table 1 contains account data, address, contact details etc. Table two contains data attached to a Person, tel no , Mobile no, Email etc. Table three contains details on what awards the person holds, i.e. one person can hold several awards.

Therefore I have a one many relationship between the first two tables and a one many relationship between the second two tables. This is set up in SQL

The first two tables are shown on a form, table 1 via a set of text boxes, table 2 via a datagrid control.

I would like the functionality whereby I could select a row in the datagrid showing the persons name and find the Persons_ID number then use that as a filter to a second datagrid view so that only the selected persons awards show in the datagrid.

Downloading Data From Remote Mysql Database

Dec 21, 2009

I'm looking into creating a program which will on program opening connect to a remote mysql database, download the data and store the data into a local file (keeping both in sync is the idea).

Getting a connection to the remote database is my first hurdle, and i'm not suceeding, i know i need to read through more info but if i could get this working it would help me tremendously.

I have attempted to connect using the mysql connector, using the server IP and port number ie. 199.002.999.000:3306 but it doesnt connect, it does connect locally ie. localhost but for some reason it won't connect to the remote server.

My other problem is that i cannot control the mysql server, i.e connections allowed remote etc, i think they're just enabled to accept connections from the server.

Is there a way to run a hidden browser script behind the scenes, download and run the file? I've tried looking for possible ways to acheive this, but have come up trumps so far.

VS 2005 Upload Data To Remote Database?

Mar 22, 2010

i write a program using vb 2005. This program collects data from Flight Simulator 2004 (altitude, speed, etc). These data should be uploaded periodically (every 10 secs) to a database which is installed to my website. The problem is that my hosting provider doesn't allow remote access to the database. Is there any way to put that data into the database?

ps. The strange with all the above is that i run a shareware program that can upload data collected from the flight to my database by simply adding the database name, user ir and password.
