hello frnd hkchauhan,
try the following example of reading using Stream Reader
Imports System
Imports System.IO
Imports System.Text
Public Class Test
Public Shared Sub Main()
Dim path As String = "c:\temp\MyTest.txt"
Try
If File.Exists(path) Then
File.Delete(path)
End If
Dim sr As StreamReader = New StreamReader(path)
Do While sr.Peek() >= 0
'This is an arbitrary size for this example.
Dim c(5) As Char
sr.Read(c, 0, c.Length)
'The output will look odd, because
'only five characters are read at a time.
Console.WriteLine(c)
Loop
sr.Close()
Catch e As Exception
Console.WriteLine("The process failed: {0}", e.ToString())
End Try
End Sub
End Class

Hi dude.
Hope this helps, it can't be easier than this:
<br />
public string LoadFromFile(string FileName)<br />
{<br />
try<br />
{<br />
string fileContents;<br />
<br />
using (StreamReader sr = new StreamReader(FileName))<br />
{<br />
fileContents = sr.ReadToEnd();<br />
}<br />
return fileContents;<br />
}<br />
catch (Exception exc)<br />
{<br />
return exc.Message;<br />
}<br />
}
Good luck

Hi,
We are creating a Code generation Tool for internal use. This tool uses a dll, which helps generate the BL and DL of the generated solution. Sometimes this dll gives an error while the Tool is run, if I give user "ASPNET" full permission on this dll, the error vanishes.
The Error is provided below:
Parser Error Message: Access is denied: 'AAA.BBB.CCC.BL'.
Line 196:add assembly="System.EnterpriseServices, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/
Line 197:add assembly="System.Web.Mobile, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/
Line 198:add assembly="*"/
Line 199:/assemblies
Line 200:/compilation
Error is in Line 198.
Does anybody know why this happens?

Where to begin...
I am responsible for a .net web application (vb.net) that I just converted to 2.0 from 1.1. The conversion was just one component of the changes involved in the current version, but it was the primary one. I have recently begun doing some stability and memory profiling tests and I am observing an alarming trend. I am really hoping someone can help me to understand how to best approach my problem.
I have created a testing environment with a server running ws2k3 and another system as a loadgun running an act script. When I apply load to my app for a number of hours it seems as though the memory consumption just keeps on rising and rising. I haven't seen it plateau as I expected to.
My app is divided into a front-end and a back-end component. These run on different servers in the production environment, each of which is running in its own application pool on the same server in my test environment. I am monitoring the consumption of memory by the app using perfmon on the server, and the following counters:
"Process.Private Bytes" (for the w3wp process)
"Process.Private Bytes" (for the w3wp#1 process)
".NET CLR Memory.#Bytes in all Heaps" (For the w3wp process)
".NET CLR Memory.#Bytes in all Heaps" (For the w3wp#1 process)
If I'm way off base with the counters to use here, please let me know. I'm the first to admit I'm at the foot of a steep learning curve here.
I was initially hoping to see the memory consumption flatten out after running the app for a short time. When that didnt' happen I added the #Bytes in all Heaps, hoping to see if the garbage collector was keeping the size of the Heaps down. I thought I could tell if the problem was with an unmanaged memory leak, or just the CLR's tolerance for memory usage being really high in .net 2.0 as opposed to 1.1. What I've observed is that both counters keep on rising and rising.
I haven't been able to kill the server with memory consumption yet, because my test database kept running out of space and stopping the test, but I've increased the space in the db, and am now running the test again for 16 hours. I am about 4 hours into the test, and the memory consumption shows no signs of flattening out.
I don't have the luxury of much time to try and figure out what's going on. Due to other issues, I wasn't able to start these tests until way too late in the development cycle, and now I'm stuck.
I know my post is probably already too long, but If anyone can help by giving me some ideas or direction. Or help me to understand what is going on enough to start affecting the behavior I'm observing.
I tried downloading the CLR Profiler, which dumps out a 500Mb log file that I don't really understand well enough to extract value from it. I've been reading lots of articles, but I can't find any info that will give me the ability to bite into my problem.
I'm on my own trying to solve this, and I'm not sure what the best way is to use the limited time between now and my approaching deadline.
This problem really has me on my heels. Any help or direction is appreciated.

AFAIK, this is the way it's supposed to work - mainly cos it needs to maintain sessions until they timeout.
Luckilly, once aspnet_wp / w3wp process will recycle once it reaches a defined limit
Nothing to see here - move along lol

Where is this value defined for IIS6 & .NET 2.0?
For .NET 1.1 the memory limit was defined by percentage in the memorylimit attribute of the process model machine.config tag.
The .NET 2.0 machine.config has no memorylimit attribute of the process model tag.
Just to clarify, are you suggesting the memory is supposed to ramp until the w3wp process restarts to clear it?

I have an asp.net website I am designing using VS2005 standard. It is installed on Win2K3 Enterprise.
In a Wizard Control, I want to take user input from two textboxes, add them together, and then display the results in a label when the user clicks a button.
I am using VB.
Here is an example of what I'm trying to do:
<%@ Page Language="VB" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Dim TextBoxOne As TextBox = Wizard1.FindControl("TextBox1")
Dim TextBoxTwo As TextBox = Wizard1.FindControl("TextBox2")
Dim LabelOne As Label = Wizard1.FindControl("Label1")
LabelOne.Text = (CDbl(TextBoxOne.Text) + CDbl(TextBoxTwo.Text))
End Sub
</script>
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Wizard ID="Wizard1" runat="server">
<WizardSteps>
<asp:TemplatedWizardStep ID="Test" runat="server" Title="Test">
<ContentTemplate>
<asp:TextBox ID="TextBox1" Text="0" runat="server"></asp:TextBox><br />
<asp:TextBox ID="TextBox2" Text="0" runat="server"></asp:TextBox><br />
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label><br />
<br />
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" /><br />
</ContentTemplate>
</asp:TemplatedWizardStep>
</WizardSteps>
</asp:Wizard>
</div>
</form>
</body>
</html>
Thanks in advance,

Hey man
Got same prob here. Just solved it. Look in the post before to track my progress on the same prob. but heres the cmd to get the values out using vb:
Dim CodeTextBox As TextBox = Me.CreateUserWizardStep1.ContentTemplateContainer.FindControl("CodeTextBox")
cheers

Thank YOU! I really appreciate it. I read your post, but apparently I didn't make the connection that it was the same problem.
It worked like a charm!

Hey man
I have given you the line how to get a control from code behind, but here is the line to commit data back to a control from code behind. This example sets the text of a text box inside the createuserwizard in the aspx page using a code behind command:
CType(Me.CreateUserWizardStep1.ContentTemplateContainer.FindControl("AllowNext"), TextBox).Text = String
Hope those help. Check out the previous thread where i was having the same prob for greater detail.
Cheers dev

I was also able to commit data back to a label by making it equal to the asp.net label first. (My grasp of these things is more limited than I'd like, but I think this is an alternate method.)
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Dim TextBoxOne As TextBox = Me.Test.ContentTemplateContainer.FindControl("TextBox1")
Dim TextBoxTwo As TextBox = Me.Test.ContentTemplateContainer.FindControl("TextBox2")
Dim LabelOne As Label = Me.Test.ContentTemplateContainer.FindControl("Label1")
LabelOne.Text = (CDbl(TextBoxOne.Text) + CDbl(TextBoxTwo.Text))
End Sub
Thanks Again,
JTok

Hi there
I've been working on this problem for ages now and it makes no sense. I have a create user wizard and wish to put variable within it, the problem is that i cannot for some reason see these variables from the code behind file. Below is a basic example of the aspx file:
<asp:CreateUserWizard runat="server" ID="CreateUserWizard1" AutoGeneratePassword="False"
ContinueDestinationPageUrl="../GeneralForms/Default.aspx" FinishDestinationPageUrl="../GeneralForms/Default.aspx">
<WizardSteps>
<asp:CreateUserWizardStep ID="CreateUserWizardStep1" runat="server">
<ContentTemplate>
<b><asp:textbox runat="server" id="txtTest"/></b>
</ContentTemplate>
</asp:CreateUserWizardStep>
</WizardSteps>
</CreateUserWizard>
Now the bolded text box for some reason cannot be seen by this web pages code behind file. Does anyone know why or have a solution.
Thank you so much in advance for any help. I'm going CrAzY!! 
Devin
