View 2 RepliesI seem to be having some challenges with the data I am retriveing from a Webpage using the Webclient class. The code works fine, however I observe that the regular expression is not picking up the negative or positive sign in the Daily_Movement data. For example, a daily movement can be -0.31 or +0.31 but the code is not picking the sign in front of the decimal values.Here is my code

I think where the problem lies is the part of the code Regex r1 = new Regex("<span class="quoteData">.*</span>"); It picks up the values between the tag quite well, but not the signs in front of it. [Code]....

I am wondering are there any standard mechanisms available to protect the asp.net asp code in the client browser ? I found some references to windows script encoders. Question is,are these script encoders encodes both aspx and code behind source ? If aspx is encoded with the windows script encoders then how client browsers can decode it? Are they aware of the encoding algorithms ?Or can we control the client browsers ( IE, Firefox, Chrome etc) to disable the view source option in the Tasks Menu when web site a loaded in them?
View 6 RepliesI have an application where I make advanced engineering/science calculations.
The application consists of 25 equal calculation "lines" which I have made as user controls:
web form:
Code:
[code]....
However the performance is quite bad because each line load from a database. Each line becomes visible when the last line has been clicked so I only need in fact 2 lines to be loaded at the beginning.
Can I make a smart code where the next user controls loads instead of the HTML that I have made, where all 25 lines appears and loads but are not visible until the line before has been used?
I'm making a page with a DropDownList (called ddlSupp) that contains several suppliers, and I populate it with an SqlDataSource, all in front code.
In another part of the page I make a CheckBoxList, and populate it again with an SqlDataSource. The select command of the SqlDataSource is a procedure call to my MySQL database. However, what the CheckBoxList gets populated with depends on who is selected in ddlSupp. How do I make a variable in front code that will take the value from ddlSupp and populate my checkbox accordingly?
Here is my code:
[Code]....
I get a MySQL error at (<%$ddlSupp.SelectedValue %>) so I know the wrong value is being passed into the query. How can I fix this?
to bring a browser window to the front based on some action?

View 3 RepliesI have a question related to <asp:SqlDataSource's SelectCommand. How to pass a querystring like <%# Eval("PhotoID") %> in the selectCommand. The whole frontend code is attached. I put
<%# Eval("PhotoID") %> and the photoid gets printed in the page.
<%# Eval("PhotoID") %> is the current displayed picture's PhotoID.
I want to pass this PhotoID or I want to pass <%# Eval("PhotoID") %> to the select command dynamically. I have tried the following approaches:
1) <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:aspnetdb %>" SelectCommand="SELECT UserName, commentDesc, uID FROM photo_comment_view Where pID = @pID"> <SelectParameters><asp:Parameter Name="pID" DefaultValue="7" /></SelectParameters> </asp:SqlDataSource> The above works but it gives only information about PhotoID 7, but there are other photos; How to set pID's value to <%# Eval("PhotoID") %> in ASP .NET's frontend page? then I also tried,
2) <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:aspnetdb %>" SelectCommand="SELECT UserName, commentDesc, uID FROM photo_comment_view Where pID = <%#'Eval("PhotoID') %>"></asp:SqlDataSource> Gives Parser error: Parser Error Message: The server tag is not well formed.
What I should do so that I can pass current PhotoID to SelectCommand? The frontend code:
<%@ Page Language="VB" MasterPageFile="~/Default.master" Title="Your Name Here | Picture Details"
CodeFile="Details.aspx.vb" Inherits="Details_aspx" %>
<asp:content id="Content1" contentplaceholderid="Main" runat="server">

how to generate HTML code from the code behind?
I would like to build a form that generate an html code inside a for loop.
I will let the user enter the photo name and No. of photos
Then I will generate an HTML code like this:
<a href="http://www.mzinj.org/images/gallery/Photo%20(1).jpg" target="_blank"> <img src="http://www.mzinj.org/images/gallery/Photo%20(1).jpg" alt="" width="345" height="247" /> </a> <br /> <a href="http://www.mzinj.org/images/gallery/Photo%20(2).jpg" target="_blank">
<img src="http://www.mzinj.org/images/gallery/Photo%20(2).jpg" alt="" width="345" height="247" /> </a> <br /> <a href="http://www.mzinj.org/images/gallery/Photo%20(3).jpg" target="_blank"> <img src="http://www.mzinj.org/images/gallery/Photo%20(3).jpg" alt=""
width="345" height="247" /> </a> <br />
depending on the No. of the photos the code will be duplicated in the loop
Then I will display the result of the loop in label or in a textarea to let the user copy it any where
The problem is that while compiling my code it considers the HTML code as a part of the behind file and gives errors on the single quote, the double quote and on the parentheses
