Asp.net - Escaping Apostrophes With Parameter Query Not Working?

Nov 28, 2011

I am trying to prevent from having to escape apostrophes in my string variables by using a parameterized query with a OleDbConnection, but it is not working. I am trying to insert into an Access db and I keep getting those pesky html codes.

Dim pConn As New OleDb.OleDbConnection
pConn = New OleDbConnection(cb.ConnectionString)
Dim SqlString As String = "INSERT INTO Strings (Mlt_String_ID, Lng_ID, Strg_Name, Sht_Text, Lng_Text, Alt_Text) Values (@Mlt_String_ID,@Lng_ID,@Strg_Name,@Sht_Text,@Lng_Text,@Alt_Text)"

Access Database And Using A Parameter Query With The LIKE Operator To Return All Rows That Match Query?

Apr 28, 2010

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.

Filter Percent (%) And Apostrophes (')?

Feb 11, 2009

I am trying to filter fields in a table that contain percent (%) and apostrophe (') characters. I kow that to filter an apostrophe you need to add another apostrophe (''). However, when a text contains the percent (%) character in combination with an apostrophe (') character, an exception is thrown. Also, when using the % character in a filter string, it will be function as an "*" (fields starting or ending with). I need the % to be considered as a character whenever the % makes part of a string in the field.

I am now able to add a row to Table1 in my database and and to populate some text boxes with that data. Now...one of those text boxes has a piece of data I wish to use as a variable/parameter in a SQL query to then populate several other text boxes. The piece of data in question is the Primary Key in a Table2. I have tried several methods I've discovered online...but nothing is working so far. So far I'm leaning towards the CommandBuilder but am unable to make it work.

Pass Parameter To A Dataset Query (.net Form App)

Jun 10, 2011

how to pass a parameter to a predefined parameter in a dataset. I've found everywhere a solution if you build the sqldata adapter and the dataset in the code. Then you can pass the parameter like: da.SelectCommand.Parameters.Add("@param1", SqlDbType.Char).Value = param1_variable (as example)

But if you have builded a dataset (with table adapters), and then in the form app you want just to pass the param1 to a DataGridView1 (as example) which is using the table adapter, I did not find how to do this.

[2005] Connecting To Access Query That Has Parameter?

Jan 8, 2009

I have this code to retrieve a record to fill out a tooltip when the user's mouse enters a cell of a datagridview.

Dim dacmt As OleDb.OleDbDataAdapter
Dim con As OleDbConnection
Dim sql As String

[Code]....

This takes way too long for the tooltip to display. So, I created a query in the Access database that takes a parameter of the first field for the record you want.

How do I connect to just the query and send the parameter to it?

I am thinking this might be a quicker way to get the data for the tooltip. But then again, maybe not.
