Im writing a small news posting system for my site and I've run into a small snag. I want each post to have a unique id but im not sure how to keep it unique. Is there an easy to find out what the last postid entered into my table was? That way I can just add 1 to the number when I go to store a new post.
Also, is there another way to do this? Am I missing something?

Why not make the ID column an IDENTITY column, that was the database will automatically create an id for you.

I am storing small peices of HTML formatted text in an XML file like so:
<br />
<stuff><br />
<item><br />
<!CDATA[[ this is some <h3>text</h3>]]><br />
</item><br />
</stuff><br />
<code><br />
<br />
When I come to display them through the ASP.NET XML control the HTML tagging in the text is parsed into its non-tag form "& lt" and "& gt" (sans spaces) so as to show on the page as the actual less than and greater than symbols rather then providing HTML tagging.<br />
<br />
Is there a way to prevent this and allow the XML control to output valid HTML that the page will then handle ?<br />
<br />
Thanks.

Maybe calling Server.HtmlEncode(html) before storing and Server.HtmlDecode(html) after retrieving could help...

Localization features are great but I have a question about them.
The Local resource file can be generated for every web form and can be used.
But if the webform changes do we need to update resource file and new contents in web form manually or is there a way to automatically update the same?
Please let me know

Hi,
As I have commented my code with xml tags. I need to run Ndoc in order to generate the help file. For NDoc I need dll and the generated xml file. In VS 2003 one can generate this file by enabling the xml documentation file option in Project properties->Configuration Properties->Build->Outputs
But I dont find this option in VS 2005. Any idea how can I generate this xml file?
Thanks in advance

In VS2005 option exists same place.
If you go to Project Properties->Build
You will find a check box named XML documentation file, enable the same and specify the output path.
Once this is done on compilation the XML file will be generated in the specified directory.
Hope it helps.

I understand your problem now.The build options I specified work with c# projects but apparently it seems that Visual Studio 2005 does not support the XML comment generation for ASP.Net projects. This article specifies an alternative for that , I have not tried may be you can have a look at it.

In our website development we had developed one video file control which takes one clip from harddrive and load and play into Internet Explorer.
Problem is that in my machine it's working fine into IE 6.0 as well as when we running from window media player it's working fine but same code and same clip is not working into different machine with same IE 6.0(same file is working into diff. machine window media player also) and it's also not giving any error also just one control square box is coming without doing any thing.
Now i had checked several check point from browser settings by allowing activex control enable and deleted offline cache but it didn't work.

Can some body help me out what is exact solution for problem?

How can i understand in my code that the opened pop-up is closed?
|
|
|
|
|
You could make it modal. Then your parent page javascript will resume when the modal window closes - you could then postback.
|
|
|
|
|
for netscape you can use dependent=yes property which automatically close popup when parent window close.
or you can use setTimeout("self.close()",10000); function which will close the popup after time you assign in second parameter.
Nav.

|
|
|
Do you want the client or the server to know the popup has closed?
For the client you could have some javascript in the popup contact the parent browser window. If you want the server to know then you could use an AJAX call from the popup to a page on the server when the popup is closed.
All assumes javascript is enabled.

hello
i m ajay
i have to implement a master detail relationship in a datagrid in asp.net2.0.
there should be a '+' buttoncolumn before every row.on click of which the detail for that row should be displayed.
for that i have made the user control for detail records for a master record and wants to open that .ascx file on click of the corresponding '+' button in the same row.
my coding is as follows-----------
master_page.aspx
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
bind()
End If
End Sub
Public Sub bind()
Try
Dim con As New SqlConnection("server=;uid=;password=;database=")
Dim sadapter As New SqlDataAdapter("select * from master;select * from detail", con)
Dim ds As New DataSet
sadapter.Fill(ds)
Dim dc1 As New DataColumn
Dim dc2 As New DataColumn
dc1 = ds.Tables(0).Columns("Id")
dc2 = ds.Tables(1).Columns("RefId")
Dim dr As DataRelation = New DataRelation("Title_Author", dc1, dc2, False)
ds.Relations.Add(dr)
dg1.DataSource = ds
dg1.DataBind()
'DataGrid1.TemplateSourceDirectory()
Catch ex As Exception
MsgBox(ex.Message)
End Try
End Sub
Protected Sub dg1_ItemCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles dg1.ItemCommand
dg1.SelectedIndex = 1
Dim dgi As DataGridItem = dg1.SelectedItem
dgi.TemplateControl.LoadTemplate("detail_page.ascx")
End Sub
master_page.html
<asp:datagrid runat="server" id="dg1">
<columns>
<asp:templatecolumn>
<itemtemplate>
<asp:button id="btn1" text="+" runat="server">
detail_page.ascx
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
End Sub
Private Sub Page_DataBinding(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.DataBinding
Dim dgi As DataGridItem = CType(Me.BindingContainer, DataGridItem)
Dim ds As DataSet = CType(dgi.DataItem, DataSet)
dg.DataSource = ds
dg.DataMember = "mms_se_template_dtl"
dg.DataBind()
End Sub
detail_page.html
<asp:datagrid id="dg" runat="server">

Hello,
I am developing a Dynamic Website's Admin Panel in asp.net using c#; I am having a problem in creating Product Ranking. Can anybody help me? I will be really thankful to you. Plz.......
Ranking means each product has a Dropdown List with it which shows its number of viewing on User Page like if a product has 4 in Dropdown List it is displayed at 4th position on user page. Moreover each Dropdown contains as many numbers as many there are products like (1, 2, 3, 4, ...) now if web admin changes one product's ranking other products' should automatically changes.
Hope you have understood it If you still confuse in understanding please contact me at abubakar.malik@gmail.com
Kind Regards,
AbuBakar

Use SelectedIndexChanged event for the dropdown and populate all the remaining dropdowns when one of the dropdown contents change.
|
|
|
|
|
I am getting all the values from the database and then bind them to the dropdown, I also want to update database as well, i dont know how to do it if you have any idea please send me some code snipshot for that.
regards

This has been puzzling me for very long time and no where has
talked about the scope of a 'On Error Resume Next' statement.
When we program ASP(.NET) pages then we usually like to let
ASP(.NET) stop at errors and report back to us. However there
are parts of our scripts that we know an error will be thrown
and we encapsulate that area inbetween:
On Error Resume Next
Err.Clear
'Try block
If Err.Number Then
'Catch block
End If
On Error GoTo 0
This is similar to the infamous try {} catch(e) {} blocks in
Java/C++, etc.
If we forget the last line 'On Error GoTo 0' then our ASP(.NET)
scripts runs over all errors thrown and we find it hard to
find bugs. So the big question is, does 'On Error Resume Next'
go out of scope when it's written inside a block
(eg. Function)?
Function Function1()
On Error Resume Next
'Our code
End Function
When the Function1 call returns, does the outside calling scope
automatically stays as it was (On Error GoTo 0)?
