View 23 RepliesI've created a log in system using a database and query builder to return the correct values, however, once the users signed in I need to bring up the rest of their data from the same table in the database. How'd be the best way of going about this? I'm not sure whether the log in should be changed to use the primary key as well.

I am connecting to an Access database and using a parameter query with the LIKE operator to return all rows that match query. The string to search for is taken from a Textbox
sql =
"Select * FROM Allview WHERE Info Like" &
"*" &
CStr(TextBox1.Text) &
"*"
The query does not return any data in vb, but when run from access with same string, there is data returned.The connection to the database is done correctly, as I am able to return data with various other queries.

View 1 RepliesI would like to create a vb form with a combo box (with song title), a text box (for song lyrics), and a button (to submit or refresh). It is linked with an access database. The combo box is populated with the songTitle field in the db (this part works fine). The text box is populated with the lyrics that go to that song The first updates fine but I can not figure out how to run a query to pass to the text box's text property. I want the user to be able to select a song from the combo box, click the button, and have the text box populated with the new song's lyrics.
Any suggestions on how to accomplish this, or a good place for a tutorial that explains the necessary elements for having vb query a database and return the results?

I am confused; I am using VB2010, IBM.iSeries.DB2 on an as400 V5R4. I am trying to establish an OLEDB connection, and return the values from the selected table to a DataGridView. I had one of the admin's make me file named GARBAGE, in the Rprtaccess catalog. In the past, I have been able to connect via access and an ODBC connection. My project is too big for access, and the SQL middleware we have is clunky and not user friendly. This is a program that will generate the SQL statements, specifically the WHERE: clause and populate the datagrid with the selected criteria. In essence I am making a user friendly striped down program, that has variables that are manipulated by the end user, and the rest, referenced tables and libraries are coded.

I am using an Access database (mdb file) and for the first time ever I'm connecting to it using a bunch of TableAdapters created in a DataSet.xsd file.I added an Insert query to a TableAdapter, and now I need to retrieve the ID (autonumber) of the last inserted record. Usually, I would send a "SELECT SCOPE_IDENTITY()" query and it would return the ID, but for some reason I cannot get this to work with the TableAdapter.
I tried two methods:1. Add the SELECT SCOPE_IDENTITY() query directly after the INSERT query in the TableAdapter. This method is described in every website I found by googling my problem. Suppose my INSERT query is this:
INSERT INTO Test VALUES("1", "2", "3")
then I should now modify it into
INSERT INTO Test VALUES("1", "2", "3");
SELECT SCOPE_IDENTITY()
I also changed the ExecuteMode to Scalar.
Ok, I run this code, but it doesn't work. It gives me an error saying Characters found after end of SQL statement.Is it because I am using Access and not SQL Server maybe? I dunno... But whatever I try it doesn't work. It's not a spelling error, and I did type the semicolon to separate the two queries so as far as I know it should work.2. Add a separate Select query (selected 'Select query that returns a single value' in the designer) that simply executes this:
SELECT SCOPE_IDENTITY()Then after using the Insert query I can simply call this query method and get the last Id. But unfortunately this doesn't work either. It doesn't even let me add this query in the designer, it says Unable to parse query text.

I am trying to query a MSI to get the ProductCode from the MSI so I can later populate a script with the proper ProductCode.During debugging it "looks" like the database is open for read, however if I look at the oDB object I see this "Error = No further information on this object could be discovered" When it tries to do the OpenView on the SQL statement it throws an exception "OpenView, Sql" I believe that is because the MSI really isn't open for read?I have added the reference to the Microsoft Windows Installer Object Library version 1.0.0.0
Here is the code: (I pass the fully qualified path + filename of the msi)
Private Sub GetMsiProperty(ByVal sMSIFilePath As String)

I'm not sure how to do the following (in VB.NET), I'm hoping you will give me some insight or examples on how it can be done. My database is an SQL one.I have an assets table, which in it has the amount, growth percentage, income percentage. There are multiple assets per client.
I need to get the amount, growth and income into three separate boxes or variables and I'm not quite sure how to do this. The only other problem is that there would be two or three rows returned also, which need to have those three variables or textboxes again.
So for x amount of rows, I need 3 variables which the amount, growth and income will go into.
The reason I need everything into variables is that I can't find an effective way of showing each assets growth over x amount of years and the income it will produce into a data grid view. I'm able to do it if I specify what the growth and income are on the form, but not through the query.
