Well, that sort of helps... But the users for the ASP page each have their own Windows account, and based on those accounts, I need to restrict access to some parts of the SQL Server (Select only in some cases, Select, Insert, Delete, Update in others.) Is there no way to pass the individual's Windows credentials through to the SQL Server through the ASP Page?

That is true that each user has their own Windows account, but for the connection to sql server it uses the app pools identity. I would restrict access to things like insert update and delete in the UI based off authenticating the user. I don't think you want to wait until the user trys to insert a record and then pass back a sql server error. The user should never be able to do the insert to begin with.
Using the app pool's identity for sql access makes it easier to manage as well. You only have to worry about giving one network user rights to stored procedures etc. Did I mention all sql access from a web service should probably be through stored procedures?
Now I would say do not try to manage the web sites sql access with your windows authentcated users, but if you still want to go down that route you can, even though I think it is a bad idea. There is an identity impersonate available in the web.config file, but that means you must use windows authentication and most likely your web app is on your local intranet.

Well, the app is only being used internaly, on our network, which is the reason for using Windows Authentication. It's never being published to the internet. I'm still thinking the ideal way to do this is going to be through SQL Permissions, though I will also be handling security on the IIS server as well. One page in particular has the ability to update and delete items from a table, but I only want select users to actually be able to do that.
So, that being said, how do I go about implementing identity impersonation? I know, it's a newbie question... But I'm still getting started with ASP stuff, coming from Windows programming.

Hello!
I'm using ASP.NET to send a response to a browser where I want to show an Excel document. This works fine but I have a problem. It only opens the workbook not Excel. I want to see the excel application with a toolbar so it will be possible for the user to save the document.
Here is my code..
Response.ContentType = "application/vnd.ms-excel";
byte[] buffer = new Byte[4096];
while( fileStream.Read(buffer, 0, 4096)>0 )
{
Response.BinaryWrite( buffer);
}
fileStream.Close();
Response.End();
Thanks for any help...

In classic ASP I successfully used:
Response.AddHeader "Content-Disposition", "attachment; filename=Report_" & Session("REPORTCOUNT") & ".xls"
Response.ContentType = "application/vnd.ms-excel"The content-disposition thing tells the browser to download the file as an attachment.
Hope that helps.

I have an asp table to which i add textboxes and values to those textboxes dynamically in the code behind. The user can edit the values in those textboxes and those are updated in the database correspondingly. Now my problem is that i have a dropdownlist in the same page and on selected index change of this i have to repopulate the asptable once again in the same manner- dynamic textboxes and values.Once i do this, the asp table is holding the same old values that were there inspite of filling the table newly. How can i solve this problem??I have not set any viewstate to true here.plz help. Its urgent!
thanks in advance

Use query string to get textbox values as the page is getting post back after drop down selected index changed so best way is use state management
you can use Session,query string , viewstate etc
Thanks and Regards

Hi All,
In which situation we use 2 databases for single Application?
Can u give me realtime Example?
Thanks
|
|
|
|
|
I currently have an application that uses 4 databases and three sql servers. The first database is a great plains database. This is where the order starts. The second database is for the web UI which is where the can add products to the order. The third database is where the web order is set for producing the product. The fourth database is used on site where the product is produced at the plant.
We need all four database to separate logical processes. The initial order entry database is in micro soft great plains, so there isn't much we can do about that one. The second database issolates our web UI. The third contains all the data needed to produce the product. The four runs on site to help track what has been produced and where it is at in production.
Hope that helps.

In a project of online shopping where number of sellers have there shops, developed in asp.net & c#.
I'm storing shopid in a session on one page and this shopid is then used to display related information of the shop .

Pls see the code:
Page_Load()
{
GVDoctorActivity.Columns[0].Visible = false; //DoctorId
}
protected void GVDoctorActivity_RowCommand(object sender, GridViewCommandEventArgs e)
{
int DoctorID;
DoctorID = Convert.ToInt32(GVDoctorActivity.SelectedRow.Cells[0].Text); // throwing exception here.bcoz it is returning null value..
}
