I have some code from this site CodeProjectLink to convert a datatable to a recordset. This code had been working fine until I changed to .NET 4 (was previously 2), now when I call the following line:

I tried changing my line to just:

But this gave the same error. The TranslateType function is correctly returning ADODB.DataTypeEnum.adVarChar so this seems valid as well

View 1 RepliesI am developing an application on VB2008 with MySql as database. I opened the connection without any errors. I have three fields/columns in my database and on the form. When I am running vb form data is not reflecting on to form fields.
I have written the following code in form load event.
'Dim cn As ADODB.Connection
'Dim rs As New ADODB.Recordset
'cn = New ADODB.Connection
'cn.ConnectionString = "DRIVER={MySQL ODBC 3.51 Driver};" + "SERVER=localhost;" + "DATABASE=in_out;" + "UID=root;" + "PASSWORD=pacvision;" + "OPTION=3;"
'cn.Open()
'MessageBox.Show("Connection Opened Successfully")
'rs.Open("Select * from deptno", cn.ConnectionString, ADODB.CursorTypeEnum.adOpenKeyset, ADODB.LockTypeEnum.adLockOptimistic)
I got a DataGrid Control that uses an Adodb.Recordset as a data source. I'd like to change the data type of the dodb.Recordset.Fields at run time. PS:I tried use the Type property but I got a message that it can't perform the operation when the object is open. Then I tried closing it with Close() but then it says the field is not available.

View 13 RepliesI have a program that looks for a file named 'license.dat' upon startup. The program first checks the directory it's in, and if the license file isn't there, it prompts the user to select the license file with a file browser dialog. I have tested this code and confirmed it working in a number of different OS environments.Recently, I received reports from two users (one in Germany and one in Italy) that the program can't find the license on their computers, even though it is present in the program's directory and they manually selected it with the file browser dialog. The only commonality I'm seeing here is a lack of English OS, but beyond that I'm stumped.This is the code I'm using:

Have you ever heard about that error ? It happened to me when I used code to Close an open form . But this very strange . Not only I have used this simple code (Me.Close) in numerous forms but it also happens in a weird way . You see , I have a form with a button on it . The code in the button's Click event sais Me.Close . Also , this button is set to be the Cancel button of the form . Now , when the user closes the form either by pressing the X button or by pressing the above button , nothing happens . However , and this is very weird , when the user presses the Esc key on the keyboard , the program crashes with this error message :
