Quite true, one observation though:
Depending on database settings, other users can read the original data while X-lock is on the row.
SQL Server uses nowadays multiversioning like for example Oracle. However, if I remember correctly, it's not enabled by default.
The need to optimize rises from a bad design

Hi,
I want to autocomplete the textbox value according to the listbox items in .net 2.0. Please give me an idea to implement this.
Thanks.

Do you mean you want somone to click on the listbox and then the value from the listbox appears in the textbox?
If so this is fairly simple as you just set the listbox to AutoPostBack = True and on the Postback take the selected value and put it in the textbox.

Hi,
Please know that Word .doc files are in a proprietary Microsoft binary format. They can only be interpreted correctly by the Office Word engine or a third party control suited for this purpose.
You may consider using the Office PIA (Primary Interop Assemblies), automate Word and open the document in it, and extract the relevant portions from the same, preserving the formatting.
Hope this helps.

This is normal. Thats why web developers spend hours working around cross-browser compatability issues.
All you can do is make changes to your css to get round it.

Hi all,
Can anybody help me out in using listbox items in the where clause of a SQL Query like "Select * from TableName where ColumnName In(Listbox Items)"
Thanks in advance

You can create a stored procedure and then in your c# set the value of the column name to Listbox.SelectedItem.Text

We have several PDF forms that we use, which call a submit.aspx to do some emailing of the form data as well as document storage (ImageRight).
Every time we submit the PDF, it calls the Page_Load sub twice. I realize this COULD be an Adobe issue but we're not getting much response from them and I feel there might be some way to check why it's happening in the code and capture it so we can stop the second process.
Anyone else ever see this problem?

If the Page_Load method is written in VB and it has a 'Handles' clause and also you have 'AutoEventWireup' set to 'true' on the aspx page, then Page_Load will fire twice. ('AutoEventWireup = true' causes all methods starting with "Page_" to be interpreted as event-handling methods for the corresponding page event).
If this is the case, either drop the 'Handles' clause or set 'AutoEventWireup' to false.

I’m getting an intermittent false negative on the call “if (!System.IO.Directory.Exists(folder))” in code in an ASP.NET 2 web site [1]. The folder clearly exists, and even contains a log file that is written to when the CLR doesn’t lie about the folder’s existence. Any help would be appreciated.

Hi All,
I an working on a website and I am trying to implement a tabbed form in ASP .NET.
I did like following in .aspx page:
<asp:menu id="Menu1" width="165px" runat="server" orientation="Horizontal" staticenabledefaultpopoutimage="False" onmenuitemclick="Menu1_MenuItemClick" xmlns:asp="#unknown">
<items>
<asp:menuitem text="" value="0">
<asp:menuitem text="" value="1">
<asp:multiview id="MultiView1" runat="server" activeviewindex="0" xmlns:asp="#unknown"> <asp:view id="Tab1" runat="server">
Contents of the Sub form
<asp:button id="cmdAdda" runat="server" text="Add the Record" tabindex="13">
|
<asp:view id="Tab2" runat="server">
Contents of the subform
<asp:button id="cmdAddb" runat="server" text="Save the Record">
|
And the code in vb .net is:
Protected Sub Menu1_MenuItemClick(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.MenuEventArgs) Handles Menu1.MenuItemClick
Dim i As Integer
MultiView1.ActiveViewIndex = Int32.Parse(e.Item.Value)
i = e.Item.Value
Label2.Visible = False
If (i = "0") Then
Me.Menu1.Items(0).ImageUrl = "~/selectedtab_app.gif"
Me.Menu1.Items(1).ImageUrl = "~/unselectedtab_tut.gif"
ElseIf (i = "1") Then
Me.Menu1.Items(0).ImageUrl = "~/unselectedtab_app.gif"
Me.Menu1.Items(1).ImageUrl = "~/selectedtab_tut.gif"
End If
End Sub
The problem is that when I click on the second tab, it is not getting clicked ( the value of i is not being 1 so that the next sub-form is not getting shown).
I am highly seeking for help.
Thanks,

Hi,
I get inputs from a formview and then place the data inside a listview via an ObjectDatasource. The binding is a "two way binding" for every control in formview. However when I insert data, the listview doesn't show anything, just adding empty rows.
I decided to check if data was reaching to ObjectDataSource_Inserting procedure and the answer was "YES". I wonder why? Do I have to add data manually inside the Listview_ItemCreated or Listview_ItemInserting procedures? I thought that there was no need to do it. What template should I use in listview for just displaying data? I have used ItemTemplating.
If you enlighten me about the solution, I would appreciate it.
Thanks.

Hi,
I am using .net 2.0. I want to connect the db dynamically using web.config. I have to pass the db name only at runtime. The server name, uid, password are static in web.config. Please help me to implement this.
Thanks.

Try to use System.Web.Configuration NameSpace There is a class WebConfigurationManager .This class allow you to accss web.config programmaticaly. For Every Section in web.config there is a Class in this namespce, like For AppSettingsSection there is a class AppSettingsSection, Similary for ConnectionString There is a Class ConnectionStringSection.
You can retreive information by WebConfigurationManager.GetSection() .
Now try to explore this area what ever i mention and try to implement. if you have anmy issue then ask me !!!
Good luck
