calling variable in different subs

Posted By:      Posted Date: September 21, 2010    Points: 0   Category :ASP.Net

How do i call a variable in different subs on the page?  I know I need to create a Private_Sub....?  But I don't know the how to complete it.  For example, I have the following code in a Button Click event.  But I also need xamount in a different Button Click for the same page.  Like I said, I believe I need something like a Private_Sub or Protecetd_Sub (not sure which one and why) with a made up name to reference it....like Private_Sub subXAmount(??????????), but I don't know how to complete it and then reference it.

Dim subAmt As String = Convert.ToString(Session("MembType"))
        Dim xamount As String = ""
        Select Case subAmt
            Case "0"
                xamount = "40"
            Case "1"
                xamount = "5"
            Case "2"
                xamount = "20"
            Case "3"
                xamount = "2"
        End Select

Local variable scoping in C#

In my previous post, Compiler-generated scopes for local variable declarations, I briefly touched on the issue of multiple meanings applied to the same name. In this post, I'll aim to flush out the compiler's rules with regards to binding names in their local scopes.

Compiler-generated scopes for local variable declarations

I was tasked with understanding and fixing a bug on error reporting with foreach iteration variables the other day, and it got me thinking about local variable scoping rules in C# in general. First, the bug.

Retrieving a variable from a previous page



I'm looking to have a search page where a user will select an item from a listview, then then taken to another page that wil display data based on their original selection.

A user will type in a string and be presented with a list of usernames that are like that string, when they select a user name who's profile they would like to view I would like the page that they're taken to, to be that users profile.

How would I transfer the variable from the search page to the profile page, and when I work on the profile page, how can I access that variable?


Embeb a variable number of videos


I need to provide some alternate content for my non-Flash users.

I have a directory of video files that is scanned using the DirectoryInfo() function, and I want to use the results to embed all files ending in ".mov" in QuickTime players on a web form.

How would you approach this? Right now I am using the count on the array of videos to determine how many times to repeat the embed code.  But this seems inelegant.

Is there a way to have a single QuickTime player.ascx control that gets duplicated according to the number of videos available for display?

Hidden variable has no value


I know I have a valid solution, but the js is telling me that the value in the hdnRecordSaved variable has no value!
Even when I specify in my function the following, it still tells me it has no value:
var myTextField = document.getElementById('hdnRecordSaved');

When I put the full value of the variable in (ctl00_ctl00_cphTopCenter_cphCenter_hdnRecordSaved.value), I get the correct contents back ("1"), which I set in my code behind. However, I would prefer to just put the short name in since the masterpages may change, etc. Unfortunately, I know I can get around this with VS2010, but we are using VS2008.

What am I doing wrong with the js naming conventions that can't give me the contents? Here is my below js.

<asp:Panel ID="pnlMapFields" runat="server" ScrollBars="Both" Height="430px">

<telerik:RadTreeView ID="RadTreeView1" runat="server" DataTextField="Description"

DataFieldParentID="MapFieldparentID" DataF

How to retrieve data from SqlDataSource and pass to a variable?


Hi there,

I have a page in my website where there is very little code-behind. I only have two lines of code in Page_Load() and the rest of the code is declarative ASP.NET code. I have a FormView control which uses a SqlDataSource to get some order information. The SqlDataSource calls a stored procedure called usp_GetOrderDetails, here's the code for the SqlDataSource:

    <asp:SqlDataSource ID="sdsFormOrderDetails" runat="server" 
ConnectionString="<%$ ConnectionStrings:ForexDB %>"
ProviderName="<%$ ConnectionStrings:ForexDB.ProviderName %>"
SelectCommand="usp_GetOrderDetails" SelectCommandType="StoredProcedure"
UpdateCommand="usp_UpdateOrder" UpdateCommandType="StoredProcedure"
<asp:ControlParameter Name="orderId" ControlID="grdOrders" PropertyName="SelectedDataKey.Value" />
<asp:ControlParameter Name="orderId" ControlID="frmOrderDetails" PropertyName="SelectedValue" />

Calling webservice from the server


I have a sample web service and aspx file. I deployed them to an existing website that contains classic asp files.

web-service: --- using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Services; [WebService(Namespace = "http://localhost/MyWebServices/")] public class MembershipRegisWebService : System.Web.Services.WebService { public MembershipRegisWebService () { //Uncomment the following line if using designed components //InitializeComponent(); } [WebMethod] public string HelloWorld() { return "Hello World."; } }

aspx.cs file: --- using System; using System.Collections.Generic; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.Services; public partial class CallWebService : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { MembershipRegisWebService mrWs = new MembershipRegisWebService(); Response.Write("Calling web service:" + mrWs.HelloWorld()); } }

It runs locally, but it shows an error when running it from the server:

Server Error in '/' Application. Compilation Error Description: An error occurred during the compilation of a resource required to service this request. Please review the follow

Session Variable issues


Hello everyone,

I ran into an issud to day with the follwoing code.  The strPanelOrder session variable is false, however, once it goes into the next if statement and sets the strTrimOrder to True, it changes the strPanelOrder session varialbe to true as well.  Why is this and how to I stop that from happening?

If Session(strPanelOrder) Is "False" Then
                If (strItemNumber.Length() = 10) And (strItemNumber.Substring(0, 2) = "FS" Or strItemNumber.Substring(0, 2) = "FC" Or strItemNumber.Substring(0, 2) = "DS" Or strItemNumber.Substring(0, 2) = "DC") Then
                    Session(strPanelOrder) = "True"
                End If
End If
If Session(strTrimOrder) Is "False" Then
               If (strItemNumber.Substring(4, 1) = "T") And (strItemNumber.Substring(0, 2) <> "AC") And (strItemNumber <> "Length") Then
                    Session(strTrimOrder) = "True"
                End If
End If


Thanks in advance for taking a look at this.

Total newbie question: Calling jQuery in an UpdatePanel?



Please forgive this ignorant question - I've used ASP.NET AJAX a good deal but I'm new to jQuery.  Specifically, is it possible to call or create jQuery events on the fly via an UpdatePanel?  For example, calling a jQuery modal or animating a Label (or <div> contained Literal), etc.

If anyone has any advice or could point me to some easy tutorials on mixing ASP.NET AJAX and jQuery, I'd greatly appreciate it.
