I am using Visual Studio 2008.
Is it anything related with ASP.Net ?
Adding Separator in Context Menu is only about using a '-' in Menu /Context Menu

I also have this problem. My research has shown that is is caused by ASP.Net opening two files and copying what's typed in one form into the other automatically. Yet when you attempt to reference a control from one form it states the above error.
My findings revealed that this problem has been around for sometime. It seems like there should be one simple correction to prevent this type of error from ever occurring. But thats just a dream.
I like to think that I understand the major parts of what causes the error. Yet the bigger question still remains ... how do I fix it?
Please help ... Thanks in advance.

Perhaps if you told us what code creates this error ?

You can Pass The GridView Row Index or Any ID that is identical with this row and send this as Query string while opening the page. And Read the data from that same id in next page.

Hello Everybody
I want to valid customer email address. What I have done so far is follows:
1. I have kept new customer details into my database
2. Also I have added a column (name emailValidation, data type bit) into customer table
3. Initially it will be 0
4. After validation it will be 1
What I want to do is:
1. After resistered I want to send an auto email to customer where I want to send a link to active his or her account.
2. When they click that link I want to change emailValidation column to 1
Please tell the best way to do it.
Thanks in Advance

Create a guid or some other unique key you can associate with the email. Put that on the URL in the email you send, so when they click on it, you can look up the email address and mark it as validated.

I think you can do like following :
Make the url like
http://www.mycompany.co.uk?custId=customer@mail.com&GUID=936DA01F-9ABD-4d9d-80C7-02AF85C822A8
While sending the Mail To Customer insert the mail id and Guid in DB or in a storage
CustID GUID
--------- ----------
customer@mail.com 936DA01F-9ABD-4d9d-80C7-02AF85C822A8
Now, When user Click on that url, he will comes to your sites, now you can retrieve CusID and GUID from query string. and validate with database if valid then you can also remove the entry from database too.
This is just my idea.

Here is another suggestion. Read this[^] article. It talks about a different approach for user account verification.
|
|
|
|
|
I have seen this free .NET library that is designed for this very occasion-
http://www.sharewareconnection.com/-net-email-validation-library.htm[^]
It does a lot of different things so you should be able to make it work with your implementation. Try it out!

Hi
I am not sure whether I am posting this in the right place, but I would like to know how I can use VB.Net ASP as an interface to copy word and WAV files from a folder on one server to a folder on another server.
Does anyone know how to do this?
Thanks

No such thing. VB.NET does ASP.NET, for which this is the forum. ASP is VBScript.

Well, that depends. If the server you're copying to is the server hosting the website, then you *could* do it that way, pretty easily.

Hi
I am having problem with my gridview not holding its checked state when being paged back and forth. I have used the code given below, which I found from another website. The only difference being that I am using a sqldatasource, and I changed it to rebind to my gridview as soon below. However, despite this, it is not holding the checked state.
Private Sub RememberOldValues()
Dim categoryIDList As New ArrayList()
Dim index As Integer = -1
For Each row As GridViewRow In GridView1.Rows
index = CInt(GridView1.DataKeys(row.RowIndex).Value)
Dim result As Boolean = DirectCast(row.FindControl("CheckBox1"), CheckBox).Checked
If Session(CHECKED_ITEMS) IsNot Nothing Then
categoryIDList = DirectCast(Session(CHECKED_ITEMS), ArrayList)
End If
If result Then
If Not categoryIDList.Contains(index) Then
categoryIDList.Add(index)
End If
Else
categoryIDList.Remove(index)
End If
Next
If categoryIDList IsNot Nothing AndAlso categoryIDList.Count > 0 Then
Session(CHECKED_ITEMS) = categoryIDList
End If
End Sub
Private Sub RePopulateValues()
Dim categoryIDList As ArrayList = DirectCast(Session(CHECKED_ITEMS), ArrayList)
If categoryIDList IsNot Nothing AndAlso categoryIDList.Count > 0 Then
For Each row As GridViewRow In GridView1.Rows
Dim index As Integer = CInt(GridView1.DataKeys(row.RowIndex).Value)
If categoryIDList.Contains(index) Then
Dim myCheckBox As CheckBox = DirectCast(row.FindControl("CheckBox1"), CheckBox)
myCheckBox.Checked = True
End If
Next
End If
End Sub
Protected Sub GridView1_PageIndexChanging(ByVal sender As Object, ByVal e As GridViewPageEventArgs)
RememberOldValues()
GridView1.PageIndex = e.NewPageIndex
GridView1.DataBind
RePopulateValues()
End Sub
My checkboxes are already disabled from user action because they are set by an image button I have on the gridview. Can you see what I need to change to keep the checked state when paging?
Thanks

Have you stepped through the code to see if the values are being stored, and what happens when the code attempts to set a checkbox ?

Hi
I think I know what's happening!
Running the code through debug in Visual Studio 2008, I noticed that the code is working, and checkbox is being re-set. However, what I have noticed, and what I believe is that the whole page is being posted back because the whole gridview is being repopulated after the pageindexchanging event has been fired.
Is there away round this? I must point out, I mustn't use JavaScript because the website is being hosted on a client where it is being switched off.
Thanks

I have about six columns, and what I am looking to do is when any one of the six columns has been sorted into ascending of decending order for that state to remain when the next column is being sorted into either ascending or decending order. However, it is not sorting on two columns I need, I need it over the 6 columns, and thus when each column is sorted its state needs to be maintained until the user has filled up the sort expression. The sort expression needs to be maintained over the paging of the gridview.
I have been given this code by a member:
Protected Sub GridView1_Sorting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewSortEventArgs) Handles GridView1.Sorting
Dim selectedColumn As String = e.SortExpression
Dim viewstateColumns As String
If ViewState("sortBLOCKED EXPRESSION Is Nothing Then
viewstateColumns = String.Empty
Else
viewstateColumns = ViewState("sortBLOCKED EXPRESSION.ToString()
End If
If viewstateColumns.IndexOf(",") >= 0 Then
viewstateColumns = String.Empty
ElseIf Not String.IsNullOrEmpty(viewstateColumns) Then
viewstateColumns = viewstateColumns & ","
End If
viewstateColumns = viewstateColumns & selectedColumn
e.SortExpression = viewstateColumns
ViewState("sortBLOCKED EXPRESSION = e.SortExpression
End Sub
Unfortunately, it doesn't sort on the first column and seems to work on only two columns, plus I am unsure how to create a sort expression to hold my sort order, which can be in any order (i.e. it is not sequential over columns of the 1,2,3, type, but could 2,1,3 , 5,1,6, etc)
So, can anyone help me, please?
Thanks

I have developed several n-tier web apps:
* business logic layer
* DALC
* presentation layer
As I understand, a Business Facade layer can go on top of the business logic layer - basically as an additional layer of abstraction. Is this correct?
How many projects have you worked on where you've used a Business Facade layer? What are the main variations of this architecture? What are the pros and cons of this architecture?
|
|

I think a more common layer is a Service Layer. Your domain (business logic) should be isolated from other layers. The first layer of isolation is the Data Access Layer, which abstracts your domain from the data store. The second layer of isolation is usually a Service Layer, or sometimes called the Application Layer. This layer is intended to isolate your domain from its consumers, presenting a simpler API to the world of consumers (presentation, other businesses, other departments, etc.) Some consider services to be part of the domain, and thats certainly a valid opinnion. The main goal is to provide a contract that the products that need to consume your domain can bind to, rather than binding directly to all the various business objects in your domain. This allows your domain and the consumers of it to vary as needed, without having broad repercussions when the domain needs to change in the face of changing business requirements.

Isn't a "Business Service Layer" the same thing as a "Service Facade"?
