I am developing a web application of which I am scanning all computers in our intranet. During the scan of each computer, I am attempting to determine if they have certain services installed or running so I will need to execute these as an administrator. I am trying to impersonate the domain administrator in the web.config and not having much luck. Here is what I put in the web.config file:

<system.web>
<identity impersonate ="true" userName ="DOMAIN\Admin" password ="password"/>

during my initialization of the web app, I am connecting to a SQL Server 2005 express database file and deleting records in case there were any left from the previous run. My code is as follows:

Dim conn As New System.Data.SqlClient.SqlConnection
Dim cmd As New System.Data.SqlClient.SqlCommand
Dim strDate As String = Now.AddHours(-3).ToString
With conn
.ConnectionString = System.Configuration.ConfigurationManager.ConnectionStrings("NetworkConnectionString").ConnectionString
.Open() 'Failed Line
End With

When I have the line in the web config shown above, I get an error on the failed line in code that says:

Failed to generate a user instance of SQL Server due to failure in retrieving the user's local application data path. Please make sure the user has a local user profile on the computer. The connection will be closed.

Based on this message, I would assume that I need to have a profile for the domain admin on the machine running the web server, which it has. Right now, the web server is on my local machine but will be eventually installed on our company's web server but I want to get this working before copying it up. All code in the web app is written in VB.NET.

If anyone has any suggestions, I would appreciate it very much. This is my first attempt at impersonation and the code I've tried to implement was from web sites specific in ASP.NET/VB.NET.

Thanks for any help!

Just for clarification, the code above:

Dim conn As New System.Data.SqlClient.SqlConnection
Dim cmd As New System.Data.SqlClient.SqlCommand
Dim strDate As String = Now.AddHours(-3).ToString
With conn
.ConnectionString = System.Configuration.ConfigurationManager.ConnectionStrings("NetworkConnectionString").ConnectionString
.Open() 'Failed Line
End With

works when there is NO impersonation line in the web.config file. It only fails when I have the "identity" in the web config file.

Hi Sarfarj

Try this.
If you are using Ajax, it will work for you.

ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "myScript", "alert(\"The record can not be deleted\");", true);

Write any Javascript you want in it.
I believe you need for Confirm, so use Confirm("Are you sure?") instead of Alert. Should work for you.

Cheers

javascript function something like:

<br />
function validateAndSubmit()<br />
{<br />
// validate the dropdownlist // I am assuming first value in dropdown list is not valid value<br />
var validFalg = true;<br />
if(document.getElementById(dropdownlist).selectedIndex == -1 || document.getElementById(dropdownlist).selectedIndex == 0)<br />
{<br />
// no value selected so set the validflag to false;<br />
validFlag = false;<br />
}<br />
if(validFlag)// valid values<br />
{<br />
var con = confirm("Are you sure you want to...");<br />
if(con)// user clicked yes<br />
return true; // submit the form, on server side save the data and display message in any div<br />
else// user clicked no/cancel<br />
{<br />
alert('data not saved');<br />
return false;<br />
}<br />
else//invalid values<br />
{<br />
alert('please select valid values');<br />
return false;<br />
}<br />
}<br />
}<br />
<br />

call the above function on button's client click like
asp:button id="mybtn" runat="server" onCLientClick="javascript:return validateAndSubmit()"

Sarfraj you and I are not on same page. The code I suggested was to validate the form on the client using javascript, not on the server. From your code it seems that you are validating the form on the server side. If you want to do this way, I'll suggest the following:

Add a panel in the aspx page like this below lblmessage:

<asp:panel id="pnlYesNo" runat="Server" visible="false">
<asp:button runat="server" id="btnYes" text="Yes" />
<asp:button runat="server" id="btnNo" text="No" />
</asp:panel>

change your code as under:

If Not _CheckingForm = 0 Then
pnlYesNo.visible = true
lblmessage.text = "Are you sure you want add this book information?"
else
lblmessage.text= "Please Check Your Input Value"
pnlYesNo.visible = false
end if

Now in click event of No button, you will hide the panel like:

Protected Sub btnNo_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles btnNo.Click
pnlYesNo.visible = false;
lblmessage.text ="whatever you want"
End Sub

and in click event of Yes do this:

Protected Sub btnYes_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles btnYes.Click
// validate the form again in case user might have changed something
Dim _CheckingForm As Integer = CheckingFormForAddingBooks()

If Not _CheckingForm = 0 Then
// save the book info, display the message and clear the form
Else
// invalid values so display the message
lblmessage.text= "Please Check Your Input Value"
End If
End Sub

----- code for my previous solution

And, if you want to follow my previous code then you have to do this:

In pageload function do this:
<code>

ibtnAddNewBooks.Attributes.Add("OnClick", "javascript:return validateAndSubmit();")

</code>

now whatever you are doing in CheckingFormForAddingBooks function you will have to convert it to javascript and do it validateAndSubmit function. And on the server side in ibtnAddNewBooks_Click function you will save the books and display successful message.

Does anyone have an idea as to how I can treat this.

Webconfig + SQL Server 2003

I tried using the Microsoft help, I am not really a decent programmer, the website we already have, is setup to function under an access database, we hired a SQL guy to bulid us the SQL tables we needed in SQL, trying to update the Webconfig to talk to the SQL server, I have failed at.

Is what I have tried to get my website to talk to the sql

<connectionStrings>
Line 17: <add name="DIMHRSDataCon" connectionString="Server=HOODNBOTC458827;Database=DIMHRS;Trusted_Connection=Yes;"/>
Line 18: </connectionStrings>

Here is our old webconfig file talking to the access database:

<appSettings>

<add key="DIMHRSDataCon" value='Provider=Microsoft.Jet.OLEDB.4.0;Password="";User ID=Admin;Data Source=C:\Projects\DIMHRS\Database\DIMHRS.mdb;'/>
<add key="DIMHRSTreeviewCon" value='Provider=Microsoft.Jet.OLEDB.4.0;Password="";User ID=Admin;Data Source=C:\Projects\DIMHRS\Database\PA.mdb;'/>

</appSettings>

Can anyone tell me how to setup my webconfig file? So I can work on the SQL server? Using Visual Studio 2003, .NET 1.1

Line 18:

If you are using .NET 1.1, there is no connectionstrings tag so you should probably use appSetting for connectionstring of SQL

Example :

<br />
<appSettings><br />
<add key="DIMHRSDataCon" value='Server=HOODNBOTC458827;Database=DIMHRS;Trusted_Connection=Yes;'/><br />
</appSettings>

Hi Mac

You can try to take a cell as a Table Instead Taking it as columns and Rows
If u r generating PDF then It is Sure it is going to Take a CEll As A TABLE

So Do it like this It may solve ur prob.

Why does the page get the postback when the user click on the third DIV?

If you wanna use the tabs in your page, you may try using Nifty Corners Cube.

Delegates are used for function callback. It is used in event handling.

Using delegates, you are setting a function reference which has to be called. It can be used for information passing between classes.
