I need your suggestions and comments because I'm having problems in which database I will be using MySQL or Microsoft SQL Server.
Which database is easier to use? In terms of connecting the database to Visual Basic 2008
Would like to know if it is possible to access a Primavera 6.2.1 database (.mdf) from VB 2008 Express. Would like to take advantage of the existing database, if possible.
It is easy enough to export to Excel and then develop an Access database, but I would like to avoid those steps.

View 16 RepliesI 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.

View 2 RepliesMicrosoft Access 2007 A Students.mdb database file Visual Basic 2008 Express Edition. I was informed that one can connect to Access files with ease from the Express Edition and most of the tutorials on the internet also show this however I am encountering a problem.
I open Visual Basic 2008 Express Edition Start a new project, with a form, and then click on the Data window, and add new data sources from the Data menu.
I click on database. The problem starts with the data connection. I click New Connection Change the Data Source from Microsoft SQL Server Compact 3.5 to Microsoft Access Database File and instead of then leading back to the other window (as happens on the tutorials for me to browse for the mdb file). Another window pops up asking me to Add a Connection.
It has the data source listed as Access and asks for a Connection String under the misc section. I type in
CODE:
When I click on Ok I get this error: Format of the initialization string does not conform to specification starting at index 0.
The Test connection button works and says connection success whether the Connection String field is empty or not but when I click OK it still gives me the same error. So I can't leave it blank either
So basically I can't connect to the Access database since I can't change the connection type and it won't just let me browse and add the file anyway.
I'm using an MS Access database which has password (database password, not a workgroup or smth). I'm using 13 characters - with no special signs- only letters. When I try to open the DB from access it works fine, but when I try to run my Windows Form application from Visual Studio Connection String, I get a message that "Not a valid password".

i am building my first VB.net application with a connection to an Access database. Now, this works fine when I debug, however when I deploy the application I get the error saying "Could not find file", which I assume means i have got one of the publishing settings wrong? I don't think it is a code error because it works when I debug, but if anyone wants to see part of it please let me know.
View 1 Repliesgood mornign here again =D having a problem with connecting to a remote database via adhoc we are using a windows 7 ultimate 32bit OS platform =D
here is the connection message im encountering
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.)
i have already enable the the Remote Connection enabling the both TCP/IP and name Pipes and its server authentication of our both msSQL server 2005 is SQL SERVER AND WINDOWS AUTHENTICATION MODE
and also i put a check in Allow Remote Connections to this Server...both our laptops...
but still encountering the problem... the default gateway of our adhoc is 192.168.137.1
sample code how i connect to the database

I 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".

Note that all the databases are in my project file.Could not find file 'C:Program FilesMicrosoft Visual Studio 10.0Common7IDEBALSAMFIR.accdbI don't understand why it works in the form but not in the user control and why it thinks it needs to find the file in Common7/IDE/.

View 5 RepliesI have a MySQL database I've created for my website, [URL]. I want to query the database, but I am unsure how to connect.
This is the code I'm using:
Code:
Dim sConnection As String = "Provider=MySQLProv;Data Source=my_database;User Id=my_user;Password=my_pass;"
Dim bSuccess As Boolean = True
[CODE]............
The MsgBox() returns a message that says: "Error: The 'MySQLProv' provider is not registered on this local machine". All I want to do is access the table in my database, is it possible? (also, without installing anything additionally?)
Does the .NET framework include ways to access MySQL databases easily?
