Access does not have "Technically" such a thing as Stored Procedures or Views, but, it allows you to treat your Queries as "such" I am assuming that you do not want to have the SQL text in your code, and that you have created the corresponding Query in your Access DB.
To call an existing query, you can use this:
Command.commandtext = "[Query name]"
DO NOT FORGET THE []
If you are using parameters, your must create and append them to the command object before the .Execute call.

I have an aspx page("for generating report") in which i have 4 table tags("" for heading of report etc.) and the rows and cells to them are dynamically created based on the values retrieved from database in the form od dataset which results 4 tables. For ex:
Dim HeaderRow = New HtmlTableRow
Dim HeaderCell = New HtmlTableCell
HeaderCell.Height = "5"
HeaderCell.Attributes.Add("ALIGN", "center")
HeaderCell.Attributes.Add("CLASS", "ins-popupheader")
HeaderCell.InnerText = ds.Tables(0).Rows(0)("Title") & " - Content Report"
HeaderRow.Cells.Add(HeaderCell)
tblHeader.Rows.Add(HeaderRow)
Now the problem is.... I have an anchor tag on my report page "Export as CSV" on click of which I need to export the contents of the page to an Excel sheet.
I tried with the following code:
Response.ContentType = "application/vnd.ms-excel"
Response.AppendHeader("Content-Disposition", "attachment;filename=Ebom.xls")
Dim dsExport As DataSet = Session("Contentds")
Dim tw As New System.IO.StringWriter
Dim hw As New System.Web.UI.HtmlTextWriter(tw)
Dim dgGrid As New DataGrid
Dim i As Integer = 0
For Each table As DataTable In dsExport.Tables
dgGrid.DataSource = dsExport.Tables(i)
dgGrid.DataBind()
dgGrid.RenderControl(hw)
i = i + 1
Next
' Write the HTML back to the browser.
Response.Write(tw.ToString())
' End the response.
Response.End()
It generates an Excel sheet but the format is not clear and I am missing some contents of my report page. I request if any one can help me in directly exporting the contents of my report page to Excel.
A quick response is appreciated........
Thanking in anticipation

Hi Everybody!!
I am new to VB.Net and require your help on
How to Add nodes to a TreeView control from a file??
I have a file containing patterns(say Patterns.txt) and each pattern has to be a node in the TreeView
The patterns are like follows:
Pattern1 - DT;FG;HK;KH;AU;BL;JC
Pattern2 - DT;GH;AU;JH;KG;JC
So, Pattern1 will be a node in the Tree and the Tags separated by semi colons will be its children. Similarly other patterns will be populated.
Please provide me with any hint or solution.
Thank you
Bye
Enjoy!!

What do you have trouble with, reading the file, or adding child nodes ?

Hi !!
The problem has been sorted out. It was rather simple than I thought it would be as VB has already provided the necessary procedures for adding nodes and I opened the file using the File System Object.
Any further suggestions are welcome.
Thank you
Bye
ENJOY !!

.... Have read about it but can't figure out the issue!
Declare WebFunction as "Save(MyNums as Array)"
Client sees MyNums as Object ... Tried a few converts.. The data in array/arraylist is just strings.
How is it done?
//Maw

|

|

I thought web services only spoke XML ? So then a document that contains the string list would be the thing.

Soooo .... then how is it done? I have data in an array-list that I want to pass though a WebService and I want the webservice to convert data to array-list and go through it and do some magic with its data. Data is always strings.
//Maw
|
|
|
|
|
The web service needs to expose a method that accepts this data. And the request will go as XML, the web service defines it's schema.

Yeah Yeah ...
Can you give me an example in code?

Welll .... have tried to pass array to webservice. Webservice is declared to take an array but wants an Object when lookin at Intellisense.
Just don't know how to do it.
Please help.... Just a simple string-array.

What's missing in all of this is the fact that you have a *specific* web service, you're not writing one, and you've yet to post any code. What does the code in the web service proxy class look like for hte method ?

( Form 1 )
Dim frm2 As New form2
Public Sub ClearProject()
frm2.TextBox1.Visible = False
frm2.Hide()
End Sub
( Form 2 )
Dim frm1 As form1
Public Sub Button1_Click(Byval sender as System.Object,Byval e as EventArgs)Handles Button1.Click)
frm1.ClearProject()
End Sub
An unhandled exception of type 'System.NullReferenceException' has occurred
Addtional Information: Object reference not set to an instance of an object
Anyone knows why there is such an error?

I presume you are trying to reference frm1 (as a form1 object) from the form 2 code yet you have neither created a new instance of the form via Dim frm1 as New form1 (an explicit Set frm1 = New form1 in the frm2 Load event would be better) nor passed a reference to it to the frm2 object.
The code sample you've provided also shows that you have a circular reference between the two forms. Not a good idea.

I assume you're showing this modelessly ?

This is a new instance of Form1, not the one that created form2. You should use delegates to do this sort of thing, or otherwise, you need to pass the instance of Form1 into Form2.

frm1 is my main form, and it will call frm2. I will get the error after i click the button that is in frm2. I tried (Dim frm1 As New form1) but it will only give another error.
Sorry but i still don't understand where the problem lies..
