hi daniel,

Thanks a lot.

I tried to create Assembly program.
I followed the steps in the site. But in Step3 i am getting error.

I dont what is this error because i am new to asp.net. Please tell me.

The Steps

Step 1 : Creating our sample component
Here is the code for the component. It just includes one method which returns a string.

imports system namespace BAJComponents public class Sample public function GetData() as string return "hello world" end function end class end namespace
Step 2 : Generate a key file
To generate the key file issue following command at command prompt.

sn -k sample.key
This will generate the key file in the same folder

Step 3 : Sign your component with the key
Now, wee will sign the assembly with the key file we just created.

vbc sampleGAC.vb /t:library /a.keyfile:sample.key
Step 4 : Host the signed assembly in Global Assembly Cache
We will use AL utility to place the assembly in Global Assembly Cache.

AL /i:sampleGAC.dll

The Error I am getting in step3:
Source file 'sampleGAC.cs' could not be found
S2007: Unrecognized option: '/a.keyfile:sample.key'

Thanks & Regards

Prya

wrong
~~vbc sampleGAC.vb /t:library /a.keyfile:sample.key~~

It should be
vbc /t:library sampleGAC.vb /keyfile:sample.key

wrong
~~AL /i:sampleGAC.dll~~

It should be
gacutil /i:sampleGAC.dll to place an assembly into GAC.

All,

How to identify a window opened with CTRL+N option, for example when a new window is opened with CTRL+N option i want to show alert message saying in 'You opened with CTRL+N option'.

Hi,

You could probably do that by checking the ASCII value of keys pressed Ctrl
and N key and then show the alert message accordingly..

How do I manipulate values in a FormView?

Rob__H24-Sep-06 16:26

Hi,

I have a FormView that is bound to an SQLDataSource.
The FormView displays the values taken from the SQLDatasource in tags like this:

<br />
<asp:Label ID="NameLabel1" runat="server" Text='<%# Bind("Name") %>'></asp:Label><br />
<asp:Label ID="AddressLabel" runat="server" Text='<%# Bind("Address") %>'></asp:Label>

Now the Address value has linebreaks in it, however of course these linebreaks to not translate to linebreaks in HTML, so I have a function to do this:

<br />
    ' Function BreakMe<br />
    ' This function replaces the line break character - Chr(10) - into<br />
    ' the HTML line break tag <br><br />
    Function BreakMe(ByVal strString As String)<br />
        Dim strSearchFor As String = Chr(10)<br />
        Dim strReplaceWith As String = "<br>"<br />
        If InStr(strString, strSearchFor) Then<br />
            Dim strBreaked As String = Replace(strString, strSearchFor, strReplaceWith)<br />
            Return strBreaked<br />
        Else<br />
            Return strString<br />
        End If<br />
    End Function<br />

How can I pass the Address value to my function before it is assigned to the Label?

Hi there,
You can call the BreakMe method in the data binding express, but the Bind method cannot be used in this context, and you use the Eval instead. Something looks like:

Text='<%# BreakMe(CType(Eval("Address"),string)) %>'

Thankyou! That works perfectly.
I was trying something very similar, but using the Bind method - but of course it makes sense to use Eval in this context.

Problems with creating a very simple composite control

RCO-Man24-Sep-06 11:59

Re: Problems with creating a very simple composite control

24-Sep-06 11:59

Hi,

I have a problem with a simple Composite Control I am trying to make.
It's in fact a superclassed control.

My projectname is SortedTextBox. My testapp is TestSortedTextBox.

SortedTextBox:

Imports System.ComponentModel
Imports System.Web.UI
Imports System.Web.UI.WebControls

<toolboxdata("<{0}:sortedtextbox runat="server">")>
_
Public Class SortTextBox
Inherits System.Web.UI.WebControls.TextBox

Public Sub Sort()
Dim arrText As String()
arrText = Me.Text.Split(" ")
Array.Sort(arrText)
Me.Text = String.Join(" ", arrText)
End Sub

End Class

In my TestSortedTextBox I have to following html:

<%@ Page Language="vb" AutoEventWireup="false"
Codebehind="WebForm1.aspx.vb" Inherits="TestSortedTextBox.WebForm1"%>
<%@ Register TagPrefix="Custom" NameSpace="SortedTextBox"
Assembly="SortedTextBox" %>

<title>WebForm1

<custom:sortedtextbox id="SrtText"
runat="server">

When I Build the project, it builds fine. However, when I want to
visualize the control (design view in VS.Net 2003) in
TestSortedTextBox, the control says "Error creating control". When I
run the project, of course I get an error at <custom:sortedtextbox
id="srttext" runat="server"> in Internet Explorer.

What do I forget? What do I do wrong?

Do you see the error details in the design view (or when you hover the error control)?

Yes, it's : Parser Error Message: Could not load type RedText.RedText from assembly RedText, Version=1.0.2459.29417, Culture=neutral, PublicKeyToken=null

What is the type RedText? I don't see it in your sample code, I think you may want to double check this type. Are you sure that this type is defined in the assembly RedText?

Re: Problems with creating a very simple composite control

25-Sep-06 21:01

Sorry, other project, but in my 'redtext' project I have the same problem. This is the error on SortedTextBox: "Parser Error Message: Could not load type SortedTextBox.SortedTextBox from assembly SortedTextBox, Version=1.0.2460.14047, Culture=neutral, PublicKeyToken=null"

Here is the VB code again. Now I checked "Ignore HTML Text in this message" checkbox of this editor. It first 'eated' my HTML text, so the first code-snippet might be confusing for you.

Imports System.ComponentModel
Imports System.Web.UI
Imports System.Web.UI.WebControls

<ToolboxData("<{0}:SortedTextBox runat=server></{0}:SortedTextBox>")> _
Public Class SortTextBox
Inherits System.Web.UI.WebControls.TextBox

Public Sub Sort()
Dim arrText As String()
arrText = Me.Text.Split(" ")
Array.Sort(arrText)
Me.Text = String.Join(" ", arrText)
End Sub

End Class

Here is the html again:
<%@ Page Language="vb" AutoEventWireup="false" Codebehind="WebForm1.aspx.vb" Inherits="TestSortedTextBox.WebForm1"%>
<%@ Register TagPrefix="Custom" NameSpace="SortedTextBox" Assembly="SortedTextBox" %>
