Using Regex to detect improperly formatted text

Mon, 29 Jun 2009 11:56:26 -0700

I am trying to craft a statement that will let me identity malformed text entered by my clients. A well-formed statement will look like the following:

{{<1 to 50 alpha characters and 0 to 5 numbers>}}

The statement I've come up with is the following, but it doesn't appear to work. There could be several of these statements in a block of text, but I want the detection to kick out after the first detected malformed tag. Any help would be appreciated.

\{\{(?![a-zA-Z]{1,50}(?::[\d]{0,5})?\}\})|(?<!\{\{[a-zA-Z]{1,50}(?::[\d]{0,5})?)\}\}(?::[\d]{0,5})?)\}\}

Examples of good input would be:
{{test123}}
{{test}}

Examples of bad input would be:
{{123}}
{{test}
{test}}

Porting ASP.net application

Fri, 26 Jun 2009 08:13:32 -0700

I have ASP.net application developped under MS Visual Studio 2003.
I ported it to MS Visual studio 2008 and it went relatively smooth, and the project built well, but when I tried to run it I got the following error:
"Internet Information Services has encountered a problem and needs to close."
The application works perfectly under MS Visual Studio 2003, but here it just crashes before it starts...
Has anyone had any expirience with a similar problem with porting code from MS Visual Studio 2003 to MS Visual Studio 2008, or does anyone have any idea why this is happening, I'd be very appriciative of any help...

Thanx in advance

Decoding special characters with Request.QueryString.Item

Thu, 25 Jun 2009 13:00:49 -0700

Hey folks I'm having a problem and I'd like your help. I'm trying to decode special characters in parameter values passed into a web page. Here's my script:

<%Response.charset="UTF-8"%>
<%@ Page Explicit="true" %>
<script language="VB" runat="Server">
</script>
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<head>
<title></title>
</head>
<body>
<%Response.Write("Amélie")%><br/>
<%Response.Write(Request.QueryString.Item("fname") )%><br/>
<%Response.Write(Request("fname"))%>
</body>
</html>

Pretty simple right? So I go to:

http://[hostname]/[path]/test.aspx?fname=Am%E9lie

And I see this in the browser:

Amélie
Amlie
Amlie

Why does this simple script mess up on on the "é" character? %E9 does decode to this letter.

I'm lost. Any suggestions?

Thanks,
-Ted

Problem with VB.NET Pages in C# Solution

Thu, 25 Jun 2009 08:40:01 -0700

I have a problem, to add VB.NET pages in C# Project. I am using .NET 2008 version. We migrated this solution from 2003 version. I am facing the following issues on my solution.

1) When I am trying to add new page(VB.NET), It is not showing option to select language. By default is taking C# language and creating aspx,aspx.cs and aspx.designer.cs files.
-- I am doing this, opened new dummy C# solution, I am able to add VB.NET pages, After that I am taking the pages from the solution folder and adding to my solution. -- This way is not correct, Please help me out.
2) When I am trying to Build my application, it is not showing errors of VB.NET at build time, but at runtime I am able to get those errors when I correct those and try again, I am able to get the functionality.
-- But this way is not correct, might be some solution properties I missed.

Saving/recalling variable help?

Tue, 23 Jun 2009 06:37:38 -0700

I am working on a project. In the generated page HTML of my ASP.NET page, I have text boxes that have onchange events that link to javascript functions that link to Ajax PageMethods which goes to my SQL command texts.

For 3 of the 4 cases, my update process works. The only one that isn't working is my "template name" section. Basically, the template name is automatically generated upon the first creation of a record. The page displays this name in the editable text box. My boss gave me an SQL stored procedure that takes the OLD name and the new name. The new name is no problem.

My question is how do I save/recall the old name? I am fairly new at all this. He explained something about a hidden text field, and I found in the code this:

 ret &amp;= "&lt;input type=""hidden"" id=""oldtemplatename"" value=""" &amp; templatename &amp; """/&gt;"

This is the generated code. What I believe it is doing is saving the templatename (this is the one that will be changed) into this hidden input field with id oldtemplatename. I don't know what to do to get this variable to my other VB function that gets called through the javascript.

Does anyone follow? Please help

Annoying problem administration tool

Wed, 17 Jun 2009 02:33:23 -0700

I work in a hospital and I am working on a local website which allows certain data te be shown, now i want to create a login but I have a very annoying problem. I have been looking all over the place but there are very few reasonable solutions.

Allow me to situate: I have a testsite in asp.net, created in visual studio 2008, so it’s a very simple page with some text where I want to log in First. I changed the authentication mode in my web.config to “Forms”. So I could run the asp.net configuration tool, here was my First problem. I couldn’t even add users, it said something about provider problems. After some research i was told that i should run “aspnet_regsl” to create databases for this. I use sql server 2005, i saw here that a database “aspnetdb” was created. I tried my toolbox again, but with no result. I then heard from some people that i should change my connection string to:

<connectionStrings>
<add name="MyLocalSQLServer"
connectionString="Initial Catalog=aspnetdb;data source=localhost;Integrated Security=SSPI;" />
</connectionStrings>

I have seen a lot of examples where this wasn’t needed, so I don’t quite understand why this had to be done with me, so I’m also not sure if this is the correct solution. Does this ahve something to do with me using sql server and not expres? Anyway I was able to add users. So I added 2, hoewever I also needed roles, but this gave me an error again, I added the following line in my web.config:

<roleManager enabled="true" />

This changed my error, but still gave me one, the error I got was:

Can’t connect to the SQL Server-database. At System.Web.Administration.WebAdminPage.CallWebAdmi nHelperMethod(Boolean isMembership, String methodName, Object[] parameters, Type[] paramTypes) at ASP.security_roles_manageallroles_aspx.BindGrid() at ASP.security_roles_manageallroles_aspx.Page_Load() at System.Web.Util.CalliHelper.ArglessFunctionCaller( IntPtr fp, Object o) at System.Web.Util.CalliEventHandlerDelegateProxy.Cal lback(Object sender, EventArgs e) at System.Web.UI.Control.OnLoad(EventArgs e) bij System.Web.UI.Control.LoadRecursive() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

I’m no expert on this, but apparently no one in our hospital is, plus people also barely have time. Does anyone know how I can fix my problem (or improve my situation)? It’s actually pretty urgent :s

Thanks so so so much for replies!

Grtz,

Checkboxlist? graphics + database input

Tue, 16 Jun 2009 01:13:03 -0700

Hi everyone!

I'm trying to create a graphical checkboxlist.
I know there are some custom controls over at CodeProject.com. But they're pretty old..

Each checkbox item consists of a graphic. When selected the background changes. The values for the checkboxitems are retrieved from a normal database file.

To give you a better view on what I'm trying to create I provide the following link: LINK

On the left side you can filter the products by size and by color.
As you can see from the source, the elements are rendered as <li>-items.

<li id='34' class="" allowselect="true"><a id='SZ_34'href="#" allowselect="true">34</a> </li>

Only thing that I find remarkable is that there's a property called allowselect. I looked up this property online but couldn't find anything useful (developping wise).

Anyone can give me a little help on this? It would be great if you have an idea how to easily create a checkboxlist like this.

Thanks in advance

Links in Calendar

Wed, 10 Jun 2009 07:49:48 -0700

Hi All,

I have displayed three values(numbers) in some of the days of the month using the calendar control. I would like to make each link clickable and when it is clicked, it would display more details on the value that the user has clicked on the same page. So my problem is that i could not wire up the call to the function that it corresponds to... could anyone help?

I have tried creating LinkButton dynamically, but it did not. I was going to try the javascript:_dopostback but i don't really understand how to do it...

any help would be greatly appreciated!

Dynamically Created TextBox Control Fails to Load Properly

Mon, 11 May 2009 23:46:56 -0700

I'm working on creating a shopping cart Control from scratch, all goes well until I get to the update portion of my shopping cart's code.After a textbox is created in the edit portion of the shopping cart, I'm unable to locate it as a child to any control.

I'm currently trying a hackish workaround where I use the textChanged event of the TextBox control, but it doesn't fire for whatever reason. I've tried quite a few different tricks and come up empty handed.

Basically, the problem is this: I'm unable to find a textbox control which is created programmatically inside this user control.I've tried to clean up the code below to hide as much of the garbage I've produced in trying to debug the problem, so hopefully it's 100% accurate.

public void EditHandler(object sender, EventArgs e) //attached to the click event of a button 
{ 
    EditButton EB = (EditButton)sender; SqlDataReader sqlDataReader; 

    SqlConnection conn; SqlCommand cmd; try { using (conn = new 
    SqlConnection(connectionString)) { 
    if (EB.Text == "Edit") 
        { 
            cmd = new SqlCommand(cmdString, conn);
             cmd.Parameters.AddWithValue(userNameSQL,Request.Co
okies[cookieName].Values[userNameCookie].ToString(
));               
    

    conn.Open(); 

    sqlDataReader = cmd.ExecuteReader(); 

    foreach (KeyValuePair pair in editList) { 
    syncTable.Rows[EB.y].Cells[pair.Value].Text = ""; //the equivalent 
    of x,y coordinates TextBox TB = new TextBox(); //THIS IS THE 
    TEXTBOX I'M UNABLE TO FIND 

    TB.ID = "tb" + pair.Value + "tb" + EB.y; TB.Width = 
    System.Web.UI.WebControls.Unit.Pixel(50); 

    TB.TextChanged += new EventHandler(TextChanged); 
    TB.AutoPostBack = true;  
    syncTable.Rows[EB.y].Cells[pair.Value].Controls.Ad
d(TB); //epic fail here 
    TB.Text = LoadValue(sqlDataReader, pair.Value, EB.y).ToString();  
    EB.Text = "Update"; 
    }
 } 
else //"Update" 
{ 
   Table tableHolder = (Table)Session["syncTable"]; cmd = new  
   SqlCommand(updateString, conn); foreach(KeyValuePair pair in updateParametersList) //updateParametersList is a Dictionary { if (pair.Value == "itemID") 
    { 
        for(int x = 0; x VandID in textboxValueAndIDList) 
        {
            if (VandID.Key == matchString) 
            { 
                s = VandID.Value; 
            } 
        } 
        cmd.Parameters.Add("@quanity", s); 
     } 
} 
    EB.Text = "Edit"; 
    } 
    else 
    { 
        cmd.Parameters.AddWithValue(pair.Key, pair.Value); 
    } 
    } //foreach //binding the data...  
    cmd.Parameters.AddWithValue(userNameSQL, Request.Cookies[cookieName].Values[userNameCookie]
.ToString()); 
    conn.Open(); using (sqlDataReader = cmd.ExecuteReader()) {   
    LoadTableRows(sqlDataReader); lblMessage.Text += "Shopping Cart 
    updated."; } } } } catch (Exception E) { lblMessage.Text += "EB.y=" 
    + EB.y + " "; lblMessage.Text += E.Message + E.Source + 
    E.InnerException + E.StackTrace; 
    } 
}

I apologize for the any formatting errors, I keep trying to fix this piece of code so it will act right, but I can't seem to fix it in places. I'd be of more use if I could view the html behind it (of course I know this to be impossible).

Server control persisting value in viewstate

Mon, 11 May 2009 18:18:31 -0700

Hi.
I am trying to get my head around implementing the persistance of a web server control value through viewstate in asp.net.

I am used to handling all state information manually in php and asp, but I know that ASP.NET has internal mechanisms for this.

I have created a control which represents a group of radio buttons. The number of radio buttons and the labels for each come from a database. I output the HTML which creates these radio button s (<input type=radio etc) in the RenderContents(HtmlTextWriter writer) method.

Through my research I have seen that data can easily be stored and retrieved using the viewstate by simply using the ViewState["something"] dictionary. That sounds simple enough, and if I retrieve the value from viewstate I could output a "Selected" attirubte on the appropriate radio button in the HTML.

The issue is, how do I get the value stored into the viewstate in the first place? The radio buttons are nothing, they are just html text output by my control. They are not objects that I can respond to a click event. I'm really not sure how this kind of thing is supposed to be implemented.

All my research into this has led to websites that talk around the concept but never seem to really hit the nail on the head. I can't help but feel there is something I am missing. Am I still thinking too 'low-level'?

Is anybody able to point me in the right direction?

For completeness, my RenderContents method is below
(I know that best practice is to use the methods of HtmlTextWriter rather than typing all the html myself, but I'm just trying to get this thing working.)

	private bool _showLabels;
	private Data.DataModel.Range _range;
	// Range is a simple class that has a question number, a count of how many options in this question, and a generic
	// list of strings to hold the labels


        protected override void RenderContents(HtmlTextWriter writer)
        {
            int i;
         
            // this makes use of the range object which describes how many radio buttons
            // should be in this range control, and what the labels of each option should be.

            writer.Write("<table border=0>");

            // output optional labels for each radio button
            if (_showLabels)
            {
                writer.Write("<tr>");
                for (i = 0; i < _range.Count; i++)
                {
                    writer.Write(String.Format("<th>{0}</th>", _range.Labels[i]));
                }
                writer.Write("</tr>");
            }
            
            writer.Write("<tr>");

            // output the actual radio button objects
            for (i = 0; i < _range.Count; i++)
            {
                writer.Write(String.Format("<td><input type=\"radio\" name=\"Q{0}\" value=\"{1}\"", _range.QuestionNo, i));
                                    
                writer.Write("></td>");
            }       
            writer.Write("</tr></table>");
        }
    }
