Set hidden values and then submit automatically

>From my page shopping cart page I want to send the amount value to the
following payment page:

</head>

The amount value should be set in the hidden input and then the form
should be submitted autmatically to the payment company. I have
problems capturing and setting the amount value.

I've tried with:

Sub Page_load()
amount.Value = 1212
End Sub

But I receive an error message from the payment company telling me that
amount is missing.

Can someone help me think clear?

Regards,

SDid you check if the value is getting set in the hidden variable before
calling forms[0].submit function?

Regards,
Augustin

If you want to set it using page_load, could you not edit your HTML source
and use:

<input type="hidden" id="amount" name="amount" value="<%=intAmount%>"
runat="server" />

and declare and set intAmount somewhere else?

set local variable with values of a dataset...

How can I set my local variables with a result in a dataset? with a sql-statement I use the sqldatareader but what's the way when i use a xml file?

Thanx!Hi siebengewald

Try this:


Dim ds as DataSet = new DataSet()
ds.readxml(yourpath & yourxmlfile.xml)
dim varLocal as string = ds.tables("yourtablename").row(numberofyourrow).item("itemname").value

It's not the best way to do it, but the shortest :-)
Are you trying to get a single node from your xml file? I'm a little confused as to what you want. Do you want to set a variable to a value from your xml file? If so what you need to do is load your xml file then perform an xpath statement to obtain your value and load it into the variable. It would be something like this..

string myVariable; //Your variable
string xDoc = "mydocument.xml"; //string to the xml document in your system
XmlDocument myDoc = new XmlDocument(); //a xml document declaration
myDoc.Load(xDoc); //loading your xml document

string xpath = "/masterNode/child::subNode"; //xpath query for the node you want. replace MasterNode and subNode with your root and sub root node.

XmlNode myNode = myDoc.SelectSingleNode(xpath); //querying the node
myVariable = myNode.InnerXml; //setting your variable to the node value

This is the simplest form of code to obtain a single node value from an xml file. Hope this helps
Jeffs way is another good solution to do it directly with the XML Classes. Just to note, my example is done with VB.net and Jeffs with C#
i load a dataset:


Dim ProdFile As New FileStream(Server.MapPath("type.xml"), FileMode.Open, FileAccess.Read)
 Dim dsProductsData As New DataSet
 Dim vProductsView As New DataView
 dsProductsData.ReadXml(ProdFile) If Not IsPostBack Then
 DLProdId.DataSource = dsProductsData.Tables(0).DefaultView
 DLProdId.DataBind()
 Else
 vProductsView = New DataView(dsProductsData.Tables(0))
 'vProductsView.RowFilter = "id='" & DLProdId.SelectedItem.Text & "'"
 GProdDetails.DataSource = vProductsView
 GProdDetails.DataBind()
 End If

now the result i got is the complete table, so i can only fill a datagrid or dropdownlist. Now is my question, can i set a local string variable to a specific row of a specific record?
Yup, you sure can! Since you have a dataset, you can just reference a record in it by:

txtBox.text = dataset.Tables("TableName").Rows(row#)("FieldName")

try that!
IT WORKS PERFECTLY THANK YOU VERY MUCH!!!
