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..

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.

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?
|
|
|
|

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" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
<HEAD>
<title>WebForm1</title>
<meta name="GENERATOR" content="Microsoft Visual Studio .NET 7.1">
<meta name="CODE_LANGUAGE" content="Visual Basic .NET 7.1">
<meta name="vs_defaultClientScript" content="JavaScript">
<meta name="vs_targetSchema" content="http://schemas.microsoft.com/intellisense/ie5">
</HEAD>
<body>
<form id="Form1" method="post" runat="server">
<Custom:SortedTextBox id="SrtText" runat="server" />
</form>
</body>
</HTML>
|

And so I have this over and over again: when I try to explain the problem to somebody else, I very often see the solution while explaining:
vb-code:
Public Class SortTextBox....
html-code:
<Custom:SortedTextBox....
It should be:
<Custom:SortTextBox....
So, the conclusion is that the name after "custom:" must be exact as the class-name. I first thought it should be the projectname. Wrong thinking...
Anyway, thanks for listening to me!

You found this before I posted my reply and in case that you're not familiar with this stuff, you can have a look at the Register directve on the web page to get more information. Basically, in the Register directive you can specify:
+ The TagPrefix like Custom
+ The Namespace containing the control class.
+ The Assembly.
and the class should be declared properly in the control markup.
|
|
|
|

I'm studying the book 'Developing Web Applications with Microsoft Visual Basic.Net' to prepare myself for the 70-305 exam. So, I am not familiar yet with this stuff. Where can I find the Register directive? I searched trough the menu's of this page (no, I am not familiar with this website either)

Ooh, you're talking about the Microsoft-page. Sorry, I was looking at codeproject.
Yes, I heard about the new generation, and there is a good chance that I'll pick it up right after this exam. Just a few chapters, then do the exam, then I am in the possession of the MCAD certificate. ( I already did the 70-306 and 70-310 exam). Anyway, this study-program is set up by my company.
The new exams are 70-328 and 70-536 right? For the MCTS.

Ah, Okay I see, you are in the progress.

Correct, and with 70-547 to become an MCPD (Web Developer), but once you have obtained the MCAD, you will only have to take the 70-551 exam to upgrade your status.

Your class name is SortTextBox, but the custom control markup is SortedTextBox.
|
|

Yeah, I found it while I was explaining the problem, but thanks for your help!
