This is the code. how do i fix it??
Public Function getData(ByVal strSplzCD As String, ByVal strSplzName As String) As clsHrmSplzAreasInfo()
Dim cnn As clsConn
Dim ds As DataSet
Dim dt As DataTable
Dim al As New ArrayList
Dim row As DataRow
Dim arr As Array
Dim str As String
Try
cnn = New clsConn
str = "Select * from HRM_SPLZ_AREAS "
ds = cnn.GetData(str)
dt = ds.Tables(0)
For Each row In dt.Rows
Dim objSplz As New clsHrmSplzAreasInfo
objSplz.SPLZCD = IIf(IsDBNull(row("SPLZ_CD")), "", row("SPLZ_CD")).ToString()
objSplz.SPLZNAME = IIf(IsDBNull(row("SPLZ_NAME")), "", row("SPLZ_NAME")).ToString()
objSplz.ACTVNSTS = IIf(IsDBNull(row("ACTVN_STS")), "", row("ACTVN_STS")).ToString()
objSplz.FNLZSTS = IIf(IsDBNull(row("FNLZ_STS")), "", row("FNLZ_STS")).ToString()
al.Add(objSplz)
Next
arr = al.ToArray(GetType(clsHrmSplzAreasInfo))
Return (arr)
Catch ex As Exception
Throw ex
End Try
End Function

The error states you have too many cursors open. Are you sure this is the code that creates the error ? If so, I assume HRM_SPLZ_AREAS is not a table, but a view, and that it uses cursors. I am imagining perhaps it doesn't deallocate it's cursors and this is the reason for the issue over time ?

No HRM_SPLZ_AREAS is a table.
The following code is to get the rows.
Public Function GetData(ByVal commandar As String) As DataSet
Dim ds As DataSet
Dim AD As OdbcDataAdapter
Try
If conn.State = ConnectionState.Closed Then
conn = New OdbcConnection("dsn=HurmisSystemOra;UID=hurmisplus;PWD=hurmisplus;")
conn.Open()
Dim Mysql As String
Mysql = "alter session set nls_date_format='DD/MM/YYYY'"
command = New OdbcCommand(Mysql)
command.Connection = conn
command.ExecuteNonQuery()
command = New OdbcCommand(commandar)
command.Connection = conn
Else
Dim Mysql As String
Mysql = "alter session set nls_date_format='DD/MM/YYYY'"
command = New OdbcCommand(Mysql)
command.Connection = conn
command.ExecuteNonQuery()
command = New OdbcCommand(commandar)
command.Connection = conn
End If
ds = New DataSet
AD = New OdbcDataAdapter(command)
AD.Fill(ds, "DataGrid")
AD.Dispose()
Return ds
Catch ex As Exception
Throw ex
End Try
End Function

OK, and which line, actually blows up ? You're obviously nesting something or somehow creating SQL that kills Oracle.

OK, and if you set a breakpoint in the code and step through, which line throws it ? The SQL that you're running, what happens when you run it in the Oracle client tools ? Does it happen the first time this code is called ?

For using Master page you need ti knwo about ContentPage, ContentPlaceHolder.
ContentPage is your pages and contentplaceholder holds content pages.
niki_nilu wrote: in my webform i have some btn,text label control which is I want to use on master page.
you need to use this as ContetPage and give the ContentPlaceholderID in it. and use content place holder in master page.
Please Check This Link Master Page in asp.net 2.0[^]
Its very good link , where you can get basic of Master Page.
if you have any problem , ask here !!!
cheers,

Hi,
I am planning to migrate asp.net 1.1 solution to 2.0,
But, after I covert the solution to VS2005 I ended up with many errors Please suggest me the available options for me.
MY SOLUTION CONTAINS 4(FOUR)PROJECTS, Each project will depend on the another project.
and each project will have its own web.config file.
I am using a 3rd party control for UI.
and after I convert the solution to VS2005. application is not running, as its resulting error saying compiler can not find few particular .dll s.
But in 2003 the name of dll are with respect to namespaces, but in VS2005 its giving some other name and finally my code is not running...
Suggest some efficient methodology to Migrate VS2003 application to VS2005.
Thanks

I have this web application that displays table/data according to a query result and edits only the selected line of output if the check box 'Add' is checked. Here is my code:
Protected Sub btnEdit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnEdit.Click
Dim forms = Request.Form()
Dim item As String
Dim strRollNo, strNewInspStat, strNewInspDateM, strNewInspDateD, strNewInspDateY, strNewInspBy, strNewInspDate As String
Dim chk As String
Dim count As Integer
For Each item In forms
If InStr(item, "Hidden") > 0 Then
strRollNo = Request.Form(item)
End If
If InStr(item, "inpsStat") > 0 Then
strNewInspStat = Request.Form(item)
End If
If InStr(item, "dteMonth") > 0 Then
strNewInspDateM = Request.Form(item)
End If
If InStr(item, "dteDay") > 0 Then
strNewInspDateD = Request.Form(item)
End If
If InStr(item, "dteYear") > 0 Then
strNewInspDateY = Request.Form(item)
End If
Dim dtecastdatemonth As String
Select Case strNewInspDateM
Case "Jan"
dtecastdatemonth = "1"
Case "Feb"
dtecastdatemonth = "2"
Case "Mar"
dtecastdatemonth = "3"
Case "Apr"
dtecastdatemonth = "4"
Case "May"
dtecastdatemonth = "5"
Case "Jun"
dtecastdatemonth = "6"
Case "Jul"
dtecastdatemonth = "7"
Case "Aug"
dtecastdatemonth = "8"
Case "Sep"
dtecastdatemonth = "9"
Case "Oct"
dtecastdatemonth = "10"
Case "Nov"
dtecastdatemonth = "11"
Case "Dec"
dtecastdatemonth = "12"
End Select
strNewInspDate = dtecastdatemonth + "/" + strNewInspDateD + "/" + strNewInspDateY
If InStr(item, "inpsBy") > 0 Then
strNewInspBy = Request.Form(item)
End If
If InStr(item, "chk") > 0 Then
chk = Request.Form(item)
If chk = "on" Or chk = "1" Then
Dim rollInfo As New Inspector(fm.posConnection)
If rollInfo.updateRollInfo(strRollNo, strNewInspStat, strNewInspDate, strNewInspBy) = True Then
lblEdited.Text = "Selected Record(s) has been Edited."
Else
lblEdited.Text = "Failed to Edit Record Selected."
End If
End If
End If
Next
End Sub
Basically i want to do is check line per line(or per result set) to get the value of the controls in that line, and if the check box is checked, it will be updated using my function "updateRollInfo". It seems that my code is getting all the values for a certain control before proceeding to the next.
I hope I am making sense and somebody can help me on this, thanks in advance!

my code is good only the declaration is..well..bad.
i replaced my declaration to
Dim strRollNo As String = ""
Dim strNewInspStat As String = ""
Dim strNewInspDateM As String = ""
Dim strNewInspDateD As String = ""
Dim strNewInspDateY As String = ""
Dim strNewInspBy As String = ""
Dim strNewInspDate As String = ""
Dim chk As String = ""
and it's working now just the way i want it. I am just wondering why my declaration made difference?

I'm programming in classic ASP but I didn't see a forum for this so I post it here. I hope somebody can help me. 
I have 2 tables, empID and deadEmpID. My app generates a new employee ID by getting the value of NEXTVAL (sequencial # from Oracle). The deadEmpID table contains a few numbers that we can not use as an employee ID so before inserting nextval into empID, I need to check to make sure this number is not in the deadEmpID table. When I run my program, if the new generated id is not in deadEmpID then it's fine... but if exists in deadEmpID, it keeps running until time out. What am I doing wrong here, please help!!
(When you reference the nextval from your sql statement, it increments to the next sequence # .)
getNextVal = "select emp_id_seq.nextval as NextEmpID from dual"
Do While True ' loop forever
Set oRS = oConnDB.Execute( getNextVal )
sNextEmpID = oRs("NextEmpID")
oRS.Close
' compare nextval make sure it's not in dead table
checkDead = "select deadID from deadEmpID where deadID = '" & sNextEmpID & "' "
Set oRS = oConnDB.Execute( checkDead )
If oRS.EOF Then Exit Do ' that empid not in dead table
Loop ' we'll go back and get another nextval and try again
'insert into employee table
sSQL = "insert into empID (empID, lname, fname) values (emp_id_seq.curval, '" & sLastName & "', '" & sFirstName & "')"
oConnDB.Execute(sSQL)

Should have used VB Forum instead 
kl010705 wrote: I have 2 tables, empID and deadEmpID
deadEmpID, nice name
Anyways, have you ever heard of break keyword. You will need to break your look once you find the new generated empid in the existing table.
Hope this helps![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

My God, I didn't really notice until you told me about the variable name!
I'll try 'break'. Thank you for your suggestion!

Hi guys,
In my ASP.NET website I have several custom controls which make use of the Page.ClientScript.GetPostBackEventReference method to achieve postbacks from client javascript. Up until now this has worked like a charm, however I find myself with a difficulty.
GetPostBackEventReference generates a reference which allows one control reference and one argument to be passed from the client to the server. Is there already a mechanism in place to parse multiple arguments from the client to the server?
It isn't the end of the world if there isn't because I could manually parse a single string into multiple arguments.
Many thanks!
Lea Hayes

Hi,
I have worked out a slightly different way of achieving what I need. Instead of manually adjusting the postback reference I have just realized that I can use hidden fields to achieve what I need.
For those interested,
1. I register the hidden field via
Page.ClientScript.RegisterHiddenField("MyFieldName", "InitialValue");.
2. This value can then be altered by javascript
document.getElementById('MyFieldName').value = 'AdjustedValue';
3. Then this value can be retrieved again on the server by:
string requestedValue = Page.Request.Form["MyFieldName"];
And that's all there was to it!
Thanks anyhow,
Lea Hayes

If you want to get client values,there are four methods.
one is ViewState,two hidden control,three session,four request.query or request.form.

Hi,
Thank you for your advice...would you be able to demonstrate how to access the view state object from the client script language? I was under the impression that the view state was not accessible by the client because it is encrypted, and compressed.
I would also be interested in an example for the accessing session information via the client.
I understand how the hidden controls, request.query, and request.forms alternatives work.
Thanks!

In fact,ViewState is the same as Session.
button1_click()
{
ViewState["test"]=TextBox1.text;
string temp=ViewState["test"];
Response.write(temp);
}
