codes in form

Code:

---

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'Put user code to initialize the page here
        Dim cap As New CAPS_BIZ1.Service1
        vdg_mrl.DataSource = cap.populateViewMR
        vdg_mrl.DataBind()

---

codes in the Service1.asmx

Code:

---

<WebMethod()> _
Public Function populateViewMR() As DataSet

        Dim data As New CAPS_DATA.Service1

        Dim ds As New DataSet
        ds = data.getDataSet("SELECT * FROM modulerecords")

    End Function

---

vdg_mrl -> datagrid name
justcaps -> database name


help appreciated >.<

i jus tried connecting to SQL 2000 instead n the error for the above was not shown
however, tis time, my datagrid showed nothing
i changed my codes to tis for the presentation layer

VB Code:

Public Class ViewMR
    Inherits System.Web.UI.Page
    Dim a As New CAPS_BIZ1.Service1
 
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'Put user code to initialize the page here
        vdg_mrl.DataSource = a.populateViewMR
        vdg_mrl.DataBind()
 
    End Sub
 
End Class

n i made sure tt i entered something in advance in the database
any1 here know wat's going on?

First, it would be much easier for me (us) to understand what you're saying if you spelled your words right. Even if English isn't your first language, 'n', 'ur' and 'de' are not mistakes, but are purposely done. They may work in chat, but on a forum like this, it gets very difficult for us to understand and read.

From what I managed to understand, it connects properly when you use SQL 2000, so my best guess is that justcaps is not a valid user in the SQL 2005 database you've created.

sorry about my english
too used to using shortcuts

ya, as u said, it keeps on gives off errors about justcaps not a valid user and etc
but now i using SQL2000 in sch

up till now, i still have problems when the page loads but the datagrid is blank on my page
my codes are the same as my other 2 friends but for some reason. even if create the database from scratch again, the datagrid shows nothing.

First, check (in SQL 2000) if justcaps exists as a user.
Second, if he does, then step through your code to the line where the dataset is filled and check to see whether the dataset is actually being filled or not. Also run your SQL statement in Query Analyzer to see if any records are returned.
