Hi all, I'm wanting to send out a notification email to all users in my forms authentication database that are in a given role. I have figured out how to do certain things based on a given users role which is cool, but is there a way to get a "user collection" from the authentication database...

I'd check the surface area configuration and firewall... lots of times that can prevent connections into a remote SQL DB.

Hi all. Can someone please help me set up a data source to a report on an asp.net application dynamically at runtime? I have everything working when I just set it up using the editor, but now I would like to programatically set the datasource at run time. Here's what I have so far, but no...

Can anybody post some code or give me some info on how to generate a checksum on an ASCII string? I have an application where I need to compare large strings, and be able to tell if the string has changed. Thanks!

http://geekswithblogs.net/mnf/archive/2006/09/01/89957.aspx Here seems to be the best explanation I have found. I modified my update query to have only the parameters I am displaying, and that works fine. Just stinks to have to maintain the update query based on what fields you have visible -...

Thanks for the help guys. I'm almost there. It works, but for some reason, I get a big gap between the gridview (which is now scrollable) and the next items below it on the page. I have tried all kinds of things, but was hoping that you'd be able to help me bring this to completion. The code...

Can anyone explain how I could put a gridview inside of a scrollable window? Basically, I'd like the header, footer, and navigation bar to be statically displayed in the browser window at all times, and then the gridview would have scrollbars to pan around in it (if it was too large to show)...

http://www.codeproject.com/dotnet/opcdotnet.asp I am using this OPC client from this page. It works pretty good - but when using it in an asp.net project, I'm having difficulty figuring out how the event callbacks should be handled properly.

Hi folks.. Quick one here for you. In a desktop version of my application, I make a connection to a data server, tell it which points I want to read - and this guy comes back with read events with the data. Works pretty good. I'd like to do this same thing with a asp.net 2.0 application, and...

Has anyone ever tried reading data via OPC in a web application? I have been able to use some open source stuff I found for desktop applications successfully, but I can't find any info for doing that in a web application (without buying some third party controls). I appreciate any input if you...

I'll give that a shot. Thanks!

<asp:SqlDataSource ID="SqlUser" runat="server" ConnectionString="<%$ ConnectionStrings:StagingConnectionString %>" SelectCommand="SELECT * FROM [User] WHERE ([UserActive] = @UserActive) ORDER BY UserName" EnableCaching="false"> <SelectParameters> <asp:Parameter...

jben: this is what I wanted to do, but in the click event, how do I access the parameter's default value to change it? That is what I'm having trouble with. I'm sorry the OP was confusing - sometimes its hard to get down what you are really after. thanks for the responses

Hi all, I'd like to change the default value of a select parameter using a link button to change the value of this parameter from True to False and vice versa. The only problem is that I don't know how to access the parameter.defaultvalue in the code. I have been able to get this to work...

Hello everyone... I would like to be able run a ping command on the client using cmd.exe. Can anyone provide some direction for me? So far, I have only found information on how to do this on the server. Thanks

Hey folks, I get a "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control." error when I enter edit mode on my DetailsView. Basically, I've added some dropdown lists in my detailsview that are populated from child table. It all works...

yeah, that seems to work pretty good... I actually ended up using some other crazy code in order to do a "copy". Disappointing that the copy wasn't really built into that class. I'm sure there is a reason! :)

I believe that the link you referenced me to covers details of the datagrid control. I'm using the gridview control, and I'm trying to take advantage of the built-in sorting and paging functionality - but I don't know how to do this without linking it to a datasource at designtime. I'm sure a...

I think I tried that originally, but then I think I lost a lot of the "built-in" features of the gridview when I broke this connection, and set it up manually - (such as the sorting and paging) - can you set up the connection manually and still setup the sorting and paging too? I'm not sure how...

Can anyone provide an example of how to create a folder on the server from within an ASP application? (When the user sets up a new project, I want to create a folder on my server with a default set of folders based on the project number automatically). I saw some information about the...
