Why not get their IP addresses? You may need to create a range of valid IP addresses from the host providers for dynamic IPs. If someone logs in with their username/password, you validate that they are using a valid IP address. It won't completely fix your issue, but it may minimize the visiblilty.

I have this 'little' problem and can't find the correct answer. The situation is:
I have a asp.net form with 2 buttons (update and delete). When i press the update-button, i'm calling a javascript-function in my aspx wich presents a confirmationbox. After pressing 'OK' i do a doc.submit wich returns to my server-code. I check if it's a postback and want to know wich button (update or delete) i pressed. Now that's exactly the problem, i can't. When i return to the server-side i don't know wich button started the action so i don't know if i ought to update or to delete. I read something about Request.Params("__EVENTTARGET") but can't get this to work. Please help me out, either clean of with a dirty workaround.

In java script function set click value in session variable or in cookies and then check on post back.
after every check clean the session or cookies for next time check.
according to your logic.

Hi,
I have 3 tables: table1, table2 and table3.
Table 1 (table1ID, Name1)
Table 2 (table2ID, table1ID, Name2)
Table 3 (table3ID, table2ID, Name3)
I have 2 DropDownLists: ddltable1SEARCH and ddltable2SEARCH.
They are both databound with the fields table1.Name1 and table2.Name2 respectively.
I also have a Datagrid: table3grid.
It is databound with the field table3.Name3.
NOTE: Please keep in mind the table relationships. My point is:
I CANNOT directly perform a search using the first dropdown. DropDown2 relies on DropDown1. When DropDown1 changes, DropDown2 changes to display available entries. THEN, the search is directly done by using DropDown2 for the Datagrid.
I have already created the view for the tables.
Therefore, I would like to know which of the following VB statements is syntatically correct when I am passing the search values from the DropDowns to a SubRoutine:
obj.SearchSubRoutine(Me.ddltable2SEARCH.SelectedValue)
OR
obj.SearchSubRoutine(Me.ddltable1SEARCH.SelectedValue And Me.ddltable2SEARCH.SelectedValue)
|
|
|
|
|
As per the Table Relationships, Table3 refers only Table2 and Table2 refers Table1.
And you are refreshing the ddltable2SEARCH list whenever ddltable1SEARCH selection changes.
So, you don't need to consider both dropdown values to fill the datagrid.
I would prefer : obj.SearchSubRoutine(Me.ddltable2SEARCH.SelectedValue)

How to change the List Item of Dropdown list via coding.
For Examle I have list item Enable, How will I change that to disable via Coding from an event handler
|
|

If you are just having one item in the dropdown list the you can clear it and then add the new item. Otherwise you have to rebind the dropdown list with the new datasource.

is there a way to have a server automatically
send out an email on a certain date. For example, if it was someones birthday,
an email saying happy birthday would automatically be sent out.

Write a simple aspx page that will send a email to all users that have a birthday (based on current date).
And then set-up a shcedulle task that will run your script every day.

Hi
I think you must use Windows Service for this task. You must questioning DB by timer. And the end you receive simple "Scheduled".

hi there....
This is the code defaultly i'm having in sample.aspx file..[ html view ],
<%@ Page language="c#" Codebehind="sample.aspx.cs" AutoEventWireup="false" Inherits="Demo.sample" %>
I converted this sample.aspx.cs file into sample.dll file successfully. Now how should i write(include) the page directory in sample.aspx file, and what are the steps to upload this sample.dll file in remote server..
Please Help me...

The page directive shouldn't need to change - when you compile the website, all the code is placed into dll's, this should then function fine - all you need to upload are the .aspx files and the dlls in the bin folder.

I have an xml file. This xml file is used by multiuser. How to store changes made by multi user at the same time to no user lost their changes from xml file.
abc
|
|
|
|
|
To maintain multi user changes on a physical file, Open the file as below:
FileStream fs = File.Open("C:\\abc.xml", FileMode.Open, FileAccess.ReadWrite, FileShare.Read);
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(fs);
Now you can read and update the xmlDoc object. and when you are done, you can use the same FileStream object to write back your changes to the xml file.
As, we used FileAccess.ReadWrite we can read as well as write to the file.
And as we used FileShare.Read we give other users only Read permission until we close the conenction.

Thanks for reply. Do you think instead of locking file, We have to used xQuery to Insert, Navigate, Update and Delte xml data. Do you have any example for using xQuery or any link of article who use xQuery for above operation.

u can use the server control drop down list and add the attribute "onchange"
add this to page load or override page init
<br />
ddl.Attributes.Add("onchange", "JavascriptFunction(this);")<br />
before i knew AJAX i used to create arrays and write them to the html page when the page is loaded, they used to contain all the items, subitems, and sub-subitems and do the same functionality using javascript only
hope this would help but i didn't try it
Best Regards
