I have an access query which plays flawlesly in Access.I want to use it as a source for a datagridview i use in one of my forms but....given the fact that is a rather big query with some "like" and conditions like ">3" and so on AND the fact it uses tables from 3 different mdb (not to mention is bases on other queries...i 'ill try my best to fix this) what is the best approach .
1st case .Can i retrieve the data simply with NO oledbparameteres and NO " select * xxx where yyy like 'd' ".I think there is a issue with the Oledb connection that "omits" them.To explain better the query right now with the filters in access returns 3 rows, without the filters 30 rows,can i get just the 3 rows to do my job... 2nd case . How should i fill a datagridview using tables from 3 different mdbs.If you can show me an example it would be life saving.

The SQL string won't return data from Access. I've tested this exact SQL String in Access and it works fine.First of all, Am I getting a SQL query from Access in the proper manner?Second... should I be using a stored procedure for this? Or is making a query from tables like this a good practice? Third, if I'm doing it right, why won't Access query return and fill my dataset?These are the results I'm getting.
Connection State = 1
Tables in Dataset = 0
Where am I going wrong?

View 2 RepliesI want to check some values in a sql db without populating controls. I can select the row i want, but for some reason my mind then hits a blank, maybe its because its monday.I want to check a few bit fields in the row and if 1 - do something, if 0 do something else. In this case depending on which bit fields are set to what, id like to enable/disable various controls on my form.
Heres the code i got so far, but as i said then i drew a blank, and i may be going about this completely wrong:Dim SQLcon As New SqlConnection("server=DEVSERVERDEVSQL;" & _
"integrated security=sspi;database=WDA_SQL")
Dim SQLqry As New SqlCommand("SELECT * FROM Users WHERE (Username = @Username) AND (Password = @Password)", SQLcon)
SQLqry.Parameters.AddWithValue("@Username", UsernameTSlbl.Text)

I converted some code from vb6 to vb2005 that opens a recordset and populates a listbox
with about 8,000 names. It uses classic ado. The vb6 code does it in about 0.75 of a second, the first vb2005 code does it in about 5.5 seconds while the second vb2005 code does it in about 4.5 seconds. Is there any way to improve the vb2005 performance a fair bit more?

View 1 RepliesI'm fairly new to VB.NET but have been programming for a while. Anyway, for the life of me I can't figure out how to properly populate a datagridview in .NET. I am using VS 2010. I add the control to the form, click the arrow on the control and select "add project data source". From there, I select Database, then Dataset, choose and ODBC data source, the table I want to use and enter the data set name.

I am working on a project that allows the user to search the database for particular records, then passes the record that the user chooses to the main form to be manipulated or changed. Yes I am aware that I could let the user change the values in the datagridview, but I do not wish to do that this way. This is the code for the event that fires when the user presses the button to return the selected row:
Private Sub returnBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles returnBtn.Click

DataGridView inserting an extra row every time I populate with data. The row appears even if I only fill the column headers. This is causing problems when I try to get values of each cell. Is there a way to avoid this perhaps in properties?
View 1 RepliesI have written some code in a form which is shown via ShowDialog from a different form. This code fills a DataGridView with data from two tables in a dataset, one through data binding, and one through more manual means. The latter part runs, or more accurately, fails to run in the same way if I call this form in the same way subsequently but without stopping debugging.

I'm working with datagridview.I found an example on the web about creating a datagridview: firs I make my array containing data, then I make a datatable from array, then I make datagridview from datatable.I don't know if it's the correct way but it seems work.In a column I make random numbers for test: for example I have on column "Time" these values: 1155, 1725, 584, 996, 1352.Then I try to sort with code when I press pushbutton: it doesn't work because I have the values:1155, 1352, 1725, 1758 (until now it seems to work correctly), but then I have 584 and 996 values: wrong!Ok, let's try with the manual sorting: same result.I filled cells with "integer" values, let's try using strings, then I used "value.tostring" same result.I also tryed to fill strings with blankspaces to obtain same length, but nothing changed. "1155", "1352", "1725", "1758", " 584", " 996".Then I tryed to fill with "0" values:"1155", "1352", "1725", "1758", "0584", "0996".The same.How can I fill cells values?

I need to run a query when I add/Change a value in my first column in a datagridview. When I add a value (a identifier from a table) in my first column, then I need the query to retrive the rest of the values in the table recordset. When I try to run a query, all i get is a query that updates my whole datagridview, and not only one row, with this code in the CellValueChanged module of the datagridview:
Me.myTableTableAdapter.FillBymyQuery(Me.myDatabaseDataSet.myTable, CType(DataGridView1.CurrentRow.Cells(0).Value, Integer))
Is there anyone who knows what I have to do, so I can add several rows to my datagridview, and let a query retrive my recordset based on my value in the first datagridview column?
