On my website, members can send messages to each other, the message is sent directly to the member's email address, I'm worried that some members can send spam to other members (I have a basic spam filter in my site but there's no guarantee it will detect all spam messages) and since the mail is sent from my site's domain I could get my domain blacklisted in free mail providers like hotmail, yahoo, gmail .. etc, any suggestions how I could avoid this?
I thought about sending the mail from a randomly generated email address that doesn't exist, e.g. 0fcc717f-43f9-4dbc-99ad-166bb22f1c2b@mysite.com (using a guid), so that if the address gets blocked it shouldn't be a problem as it will not used again anyway, how effective is this in your opinion? will my whole domain be blocked if any spam sent from it?
Thanks for your suggestions ...

Without knowing anything about your site, how about restricting the number of emails any member can send in a day?

Hi Bob, thanks for your reply but actually my question is not about how to fight spam on my website it's about how to make messages sent from my website get through the spam filters of the major free webmail providers like hotmail, gmail, yahoo, aol .. etc, and also how to avoid having the domain of my website blacklisted on those mail providers (which will consequentially cuase any mail sent from my website to end up in the junk/spam folder), by the way, I already implemented some restrictions on the number of messages a member can send per session but not a limit (if a member sends more than x messages per session, they will have to pass a captcha for every message they send after this in the same session, like what happens in popular social networks like myspace and hi5) ..
regards

Hi,
I am not sure what you meant by another sql server. Yes you can connect to multiple sql server through your website. Its up to you how you manage your connections. You could use GridView, DataList etch controls to access your Db but not sure what exactly you are trying to achieve.

Hi Jaffer,
Well sorry for the incomplete description. Ok, I have a client(say Pups) who needs his clients to access their information over the web. This entails that when that client logs in over the web, I must read their login information which is stored in Pups SQL Db on Pups server. Also for new clients of Pups who need to register over the web, to be able to trade with Pups, I need to Update his sql Db.
I am still new to ASP.net and web development and are not familiar with all the controls. I have however tried to adjust or change asp.net configuration and Provider but with no success.
Please if you can help me and put me into the right direction. If the information is still not enough I will elaborate more should you have more questions.
Thank you very much
WOW

Hi,
Are you using 2 sql servers? Because from the description i am still unable to completely understand your problem.
What i understand from your description is you might be having 2 sql servers one called pups. Okay when pups clients access pups application over web you might say you establish connection to the server using connection string 1 hitting pups database server. And when you need to connect to another database server you should use connection string 2. This logic should be embedded in your program to determine which database it should access at any particular moment.
I am assuming you know about connection string and know how to connect to a sql server in asp.net

Hello all, please forgive my newbie-ness.... (at ASP.NET)
I have a tabcontainer on my masterpage where each time a tab is clicked it actually shows a different .aspx page for each tab. First, I'm not sure if I'm even going about this the right way. It works, but it's kinda slow and a very visible transition.
I just call 'Response.Redirect()' in the 'ActiveTabChanged' event depending on which tab was clicked.
Secondly, even though this works to switch from page1 to page2, it always shows the active tab as the first one after clicking on the second one, even though the second page is now showing. I even tested setting it back explicitly, and it still doesn't work.
protected void TabContainer1_ActiveTabChanged(object sender, EventArgs e)
{
switch (TabContainer1.ActiveTabIndex)
{
case 0:
Response.Redirect("default.aspx");
break;
case 1:
Response.Redirect("default2.aspx");
TabContainer1.TabIndex = 1;
break;
}
}
Thanks in advance

Hi,
I am relatively new to ASP.NET with AJAX, and have a couple of performance related issues I am experiencing, and was wondering if anyone could offer some pointers.
I have quite a basic page, with 1 ScriptManager, and UpdatePanel, and 4 Collapsible panels on the page. Inside the collapsible panels, there are some labels and textboxes that are databound to various data sources. I have one button that calls an update to the database. This call happens Asynchronously as I expected as all the data controls and button is inside the UpdatePanel.
All works wonderfully locally.
On the production webserver, nonlocal users are complaining of slow performance. I have no narrowed it down to the size of the page.
I am using the WebDeveloper addon in Firefox to look at the resultant page.
Here are the results :
Documents (1 files) 28 KB (86 KB uncompressed)
Images (7 files) 15 KB
Scripts (5 files) 100 KB (540 KB uncompressed)
Style Sheets (2 files) 1 KB (3 KB uncompressed)
I have setup IIS6.0 to compress static content, as well as ASXP , AXD , CSS , JS etc.
I have not added an Javascript myself, so the script files are all compiler/control related.
Is this sort of size normal ? How do people get good performance from pages that download over 100k of scripts, for a few controls.
Any pointers would be greatly appreciated ?
Thanks,
Steve

You may be able to trim some of the image files down, or you may even be able to use some sprite-based magic to combine them together.
The document size (28KB) is not particularly big, but again you may be able to trim this down by removing unnecessary markup and making better use of CSS classes.
Your big resource hog seems to be the javascript files totalling 100KB, which I imagine must be some kind of javascript framework (prototype, jquery etc? 540KB uncompressed is really quite monstrous!). Most frameworks offer a compressed version which drastically reduces the size of the framework, or you may want to consider javascript compression in addition to server compression - combining your files into one and then JS compressing will have a much greater effect.
On top of that I would just verify that your site is setup to allow correct caching of static files.

Hi,
Thanks for the feedback.
I found I was using the debug version of the framework, dropped about 200k.
Am working on combining the files as we speak, and will look at the compression and server setup in depth,
Am looking forward to an optimized experience.
Thanks for the help.

Just create new image controls and add them to the page, although it seems a strange thing to do.

Hi,
I want to know what is the best tag to use when making a piece of text a different color. I always used to use the <font> tag, but Visual Studio said that it is "outdated". So what should I use now? The <span> tag?
Please can someone advise?
Thanks
Brendan

Use CSS, the idea of which it to separate out your style from your content as much as possible.
