Getting Datagrid to display SQL results with ADODB connection

[WalterHeisenberg]

Hello,

First I'll make no attempt to hide I am an absolute beginner when it comes to VB. I've been given an application and asked to "enhance" it with no prior vb experience.

Thus far I've made the "eye candy" changes needed with various labels and check boxes etc. However, I cannot get the results of a SQL query to display in a datagrid using the DBGrid control. I have been able to display items in a listbox but ultimately I will need to get this datagrid working.

After building my query based on user input, I am using:

  Set rst = New Adodb.Recordset
    rst.Open sql, cn, adOpenStatic, adLockReadOnly, adCmdText

where sql is the SQL statement and cn is the connection string. Again, I can results to display in a label or listbox but can't get them to show on the datagrid. I tried adding, "set DBGrid.datasource = rst but get "class not support automation or does not support expected interface". Many thanks in advance for help!

I'm thinking the DBGrid is designed (and I don't use them so I could be corrected on this) to be used with the bound data controls you can add to your form rather than to work with dynamically created recordsets.

You could replace it with a 'Microsoft Datagrid Control' instead and the syntax you used in your post will populate that grid with records (as long as you specify the cn.CursorLocation = adUseClient).

Hope this helps

Just an update, the code I had inherited was part of an Enterprise Application and as such I was running into problems with the controls I could use. I am going to rewrite this as a windows app. so I have more information at my fingertips. I'm sure I'll run into problems shortly! . Thanks,
