How to upgrade .net framework 1.0 into 1.1?is there any tool for that
|
|
|
|
|
You simply download the .net framework 1.1 and install it. The versions 1.0 and 1.1 can run side by side, but you can remove the old one if you want. The link below can give you more information:

I am posting this question fourth time and i will continue posting this question until i get the answer.
Sir,
I have a datagrid and problem lies into the edititemtemplate of datagrid.
I have a datagrid in the following format
--------------------------------------------------
Column1 Column2 Column2
abc1 EditImage Delete Image
abc2 EditImage Delete Image
abc3 EditImage Delete Image
-------------------------------------------------
Now when i click at the particular editimage then the control goes to the the edititemtemplate where i am using a function to construct a table in that particular row of the datagrid in which i clicked at the editimage .In the edititemtemplate i am calling a function in the following format.
------------------------------------------------
<%#LoadTable(Container.DataItem(0).ToString())%>
--------------------------------------------------
Now the table is not comming into that row but a message is being displayed in that row and the message is
System.Web.Ui.HtmlControls.HtmlTable
But i want the structure of the table instead of this message .
------------------------=---------------
I am using the following code in the LoadTable
function
----------------------------------------
Public function LoadTable(Byval str as string)as Sysytem.Web.Ui.HtmlControls.Table
dim con as new oledbconnection("connectionstring")
con.open
cmd=new oledbcommand("select * from abc where id=" & str , con)
cmd.executereader
dim dr as oledbdatareader
dr=cmd.executereader
dim t as new system.web.ui.htmlcontrol.table
dim drow as System.Web.UI.HtmlControls.HtmlTableRow
dim dcell(1) as New System.Web.UI.HtmlControls.HtmlTableCell
--------------------------------------------------------
while(dr.read)
drow = New System.Web.UI.HtmlControls.HtmlTableRow
dcell(0) = New System.Web.UI.HtmlControls.HtmlTableCell
dcell(0).Width = "30%"
dcell(1) = New System.Web.UI.HtmlControls.HtmlTableCell
dcell(1).Width = "70%"
dcell(0).InnerText = dr.Item(0)
dcell(1).InnerText = dr.Item(1)
drow.Cells.Add(dcell(0))

Hi,
I need to design a portal based on DOTNET. The requirement is to facilitate software downloads through the proposed portal.
1. big downloads(softwares/patches) will be there.
2. Need to track users based on tokens issued to there and we need to make sure only those with valid tokens will be able to download the particular software.
Please do let me know your thoughts.
Thanks

IMO, you may use a seperate web page .aspx or a custom http handler to implement the download functionality instead of using a static link. Doing so, you can authenticate the user and track the user action. Jesse[^] can give you the sample code.

Hi guys,
I have implemented a simple client callback functionality (which works fine), that upon clicking an html button only a portion of the page accesses database and changes a field. Then within the same javascript I have a timer go off and once 90 seconds elapses, it changes the properties of certain fields/controls on the page. Now, my challange is to access the database again once the 90 seconds has passed and change a couple of the data fields... I cannot think about a way to do this! Can somebody PLEASE PLEASE PLEASE help me?

Hi there,
IMHO, you can use the setTimeout/setInterval methods to implement the client side timer, then once after a specified period of time, a custom client side function is called and you can use it to update the DB with ClientCallback. You can easily find the exampples of these two functions out there.

Thanks a bunch for your help, though Im still a little confused
I have my connection strings stored in web.config for the data access layer to deal with, and don't like the idea of accessing database directly from a javascript... I was hoping to be able to do yet another callback for that purpose(you know, like going through RaiseCallbackEvent and GetCallbackResult again). But in order to do that I had to wire that particular javascript to a specific control's Attribute collection (this.someControl.Attributes.Add("", "")...
Would you happen to know of a good article or two that may shed some light? Thank you so much

I took your advise and looked around; after putting together parts of other people's solutions I finally was able to get it right. Turns out I had to provide yet another callbackEventReference (with a function named Release(arg, context)) that would tell my server to do something, and I called that function from within the timer function... long story short, it worked and Im super happy

Hi i have a compare validator to validate a date field:
<asp:comparevalidator id="CompareValidator1" runat="server" type="Date" operator="DataTypeCheck" controltovalidate="txtDateOfOrder" errormessage="Please enter a proper date">
If i enter the date in the dd/MM/yyyy format the validator throws the error message as it wants the date to be in the MM/dd/yyyy format.
I want an dd/MM/yyyy format to be entered in my textfield.
my web.config has:
<globalization fileencoding="utf-8" requestencoding="utf-8" responseencoding="utf-8" culture="en-US" uiculture="en-US">
How can i make the validator to accept dd/MM/yyyy format????
Thank,
Sanded

I think your validation expression should read something like this:
\d{2}/\d{2}/\d{4}
but then again, this would also apply to mm/dd/yyyy...
why don't you use the CustomValidator control? that way you can write it the way you want it.

+ The simple way to know the id of the textbox at the client side is to view source the web page. Or you may want to look at the ClientID property from the server side code.
+ Also, to pass the value of the TextBox from the server side, you first need to get reference to the TextBox control like you are doing in the ItemDataBound, then you simply access the Text property of the control.
