Sharepoint: Web Part vs. ASP.NET User Control - sharepoint

When creating web parts for Sharepoint, is it better to create an actual web part, or is using and ASP.NET User Control (.ascx) just as good?
I already know how to create the user controls that I need, so it seems like the extra effort of creating a web part is just unnecessary leg work.
What are the advantages of using a web part over just creating and ASP.NET user control?

I am a big fan of user controls except for the simplest web parts. I create a webpart that instantiates and loads the user control. There are other tools out there that you can use to expose your user control, like smartpart, but I would suggest you wrap it up yourself, as it is a good learning experience. Once you have done it once, you basically have a template for any other webpart you want to create.
Good Luck!

A bare ASP.NET ascx control would have to be added to a custom layout page. This limits the utility of the control a little as it cannot be added "just anywhere".
Having a webpart gives the flexibility of the control being added to the site multiple times in different locations or even multiple times on the same page with different properties.
As has been mentioned it is good to use CreateChildControls() to create the controls in the webpart and it is not that much of a big deal to code and package a webpart into a solution, making it worth the extra effort.
Webparts are also able to accept connections from "filter" webparts on the same page, giving additional flexibility to webparts compared to hosting ascx controls on the site.
When it comes to editors using the site, it makes a lot of difference for them to be able to add a webpart compared to editing a page layout, publishing it and then creating pages based on that page layout, so from the perspective of a site editor, the difference in usability is really quite large.
I recommend going even further and coding your webpart to use an xslt file to display the contents and making the location of that xslt a configurable property of the webpart. This really adds to the flexibility of your control.
Look at the Dataview webpart to see how much can be done with the addition of custom rendering.

I want to implement SharePoint, but I want to design it my way

I am aware of a program called "SharePoint Designer 20xx), and I would like to know if any of you have modified the default master page to make it.. less confusing and more simplistic. Can this be however I want it or is there limitations?
I also found this:
http://www.expertsharepointconsulting.com/images/Blue%20Large.PNG
I would like to implement a design similar to this! If I were to download a "Free sharepoint master page", would this design only work for the main page of SharePoint? as in if I were to go from the newly added masterpage, to a page called "reports", would it be completely different? If so how can I get around this?
You can create customized masterpages whichever way you want. Usually you don't touch the default ones, specially because you can break some system pages with that. Just create new ones from them or from the minimum.master one.
As an example of a Sharepoint Website using a very customized master page I can point you to a publishing website project I was involved for a Portuguese company: http://www.ana.pt/en-US/Pages/Homepage.aspx
It's all Sharepoint 2010...and it is fully customized
You can of course use the same template for all pages, just have to set it on the root site and say that all sub sites inherit from it.
To achieve the level of design changes you see on that web site you have to build new master pages, page layouts, use JS, CSS and user controls (the website uses little to no web parts).
we don't use Sharepoint designer because that would mean the files becoming unghosted, which can be pain sometimes, and sharepoint designer is not a very good tool.
The way we do it is by implementing everything on visual studio and deploying it via WSP packages. This way everything stays ghosted on the file system. You can check an example here:

How to add an application page to a site in SharePoint?

I am an experienced .NET Developer acting as interim SharePoint Developer, and am new to SharePoint. After determining that I need to go with an application page instead of a site page for a new project due to it's complexity and need of custom code behind. Before developing the entire solution, I wanted to tie up the loose ends of my understanding of application page deployments. I need to add this page as a URL on the left side of a Site Collection page (kind of like what happens when adding a subsite to a site page.) I have read about the modules, which seems extremely hacky to me. There must be a better way to develkop a custom page on top of SharePoint without the page being accessible to anyone on the entire site.
EDIT
The application I am wanting to develop on top of SharePoint exists purely for data entry and reporting purposes.
Have you considered using a Webpart?
With a visual webpart which is essencially a usercontrol wrapped in a webpart you can add as much complexity as you want and you also have code behind to hook to events etc.
The benefit of using a webpart is that you can then drop it on a page, and use all OOB sharepoint access controls.
You mention that you want to develop a data entry reporting app. So something you can do is to create a subsite. Look all access to modify pages except to owners. Create all your screens by adding pages to the subsite and dropping webparts on it with the logic you require for each screen.
Also make sure you deploy the werbparts via a web feature that only is activated in your subsite, this way the webparts are only available in that particular subsite.

SharePoint 2010 Solution

I'm creating a Site Definition for SharePoint 2010 using VS 2010. Have some questions:
How do I limit the page layouts to the custom ones that I created?
I created a custom Home Page layout. How do I by default create a page based on this page layout and set it as the welcome page for the site?
Your implementation approach (either declarative or programmatic) isn't indicated in your question so I am only assuming that you are building your custom site definition declaratively (with CAML). You will find that creating a custom site definition declaratively is pretty painful, especially when debugging. It usually involves making changes to the onet.xml file and just hoping things go right during deployment and/or site creation.
When developing custom site definitions, I find it easier to forgo the declarative mess and staple a custom feature to my custom site definition, allowing me to build the site up with code. Andrew Connell has a blog post to this effect:
http://www.andrewconnell.com/blog/archive/2008/02/15/You-dont-need-to-create-site-definitions.aspx
(Disclaimer: yeah, it's old, but still quite relevant, in my opinion)
Now that your tasks are programmatic (allowing you to debug, log errors, and generally have more visibility into the SharePoint magic) you can initialize your new SPWeb object as you see fit via the SharePoint object model.
Setting the available page layouts.
Setting your custom page as the homepage (after you add it to the Pages library).
Perhaps someone else can enumerate 100% declarative approach; I'm sure it's ugly, as is most CAML.

MOSS 2007: Displaying data from SQL Server Database

I have a requirement to select some data from a table in a database (SQL Server) and display it on a page in a SharePoint site (MOSS 2007).
I have a little bit of experience of MOSS, so I know I have a couple of options:
BDC
SSRS
or possibily even a custom ASPX page.
I've never really worked with any of these. Can anyone advise on the +/-'s of each?
It all depends on what functionality is required once the table is displayed in SharePoint. Do you need extra bells and whistles or is a dump of the data adequate? (Think about the future as well.) Here's some thoughts...
Business Data Catalog (BDC)
If you want to nicely integrate the SharePoint look and feel with your data as well as get some cool functionality, BDC is a good solution. There is no need to program anything and these are the features you get. However if this data will only be used once in one way then it is probably overkill.
You would need to roll your own XML description of the data so SharePoint knows how to pull it from the database (or use something third party like Lightning Tools). As Colin mentioned it requires the Enterprise license of MOSS.
SQL Server Reporting Services (SSRS)
If Reporting Services is already available for use then this is the quickest and simplest solution. It works well but can get painful as more advanced features are required in your reports.
You should be able to use the Report Designer wizard to point to your table and set everything up for you. There are SSRS web parts that can be used within SharePoint, or indeed you can run SSRS inside SharePoint using SharePoint integration mode.
Application Page
This method Steven mentioned lets you integrate an ASP.NET application into SharePoint (such that it can be accessible by a URL within your SharePoint site). This allows anything that ASP.NET does, and the code-behind will be aware of SharePoint so you can tap into that if needed as well. The cons here are code access security and deployment.
See this webcast for how to do it.
Web Part
Similar to developing an application page but much more integrated with SharePoint. A custom web part is very powerful and allows you to integrate ASP.NET code on a SharePoint page. As you would know web parts can be dragged to whatever location and give a consistent properties pane. Again, code access security and deployment needs to be considered.
If you like designer view in Visual Studio then be aware this isn't the approach that Microsoft push. You can however use something like SmartPart where you would develop your custom app as a user control and the SmartPart wraps it into a web part. I'm used to doing it the MS way now and actually prefer the additional control this gives, however it can take more time.
Page Viewer Web Part
If you don't want to touch your SharePoint installation at all then have a look at this web part. It takes a URL as parameter and displays an IFrame containing the page that would be your report, either in SSRS or standard ASP.NET.
The downside from this lack of integration is problems with sizing the IFrame, and possible security warnings from the browser if accessing the URL in a different domain.
Don't forget the DataView Webpart. It has a pretty small developement footprint and works really well as a first "cut" if you are unsure as to how hardcore you need the final result to be.
It renders using XSLT, giving you full control of the final HTML, so it can do some pretty things with Javascript and co.
For a very simple example of charting.
Have you ever used the .NET Framework do develop webpages?
MOSS 2007 uses this framework for master / template files.
So your best choice would be to create an ASPX template file to display the results on the webpage.
BDC is the way to go if you want to keep it "strictly Sharepoint". The problem is, it is only included in the Enterprise edition of SharePoint. If you have the Standard edition, you could go for SSRS and the SSRS webpart, or, create your own webpart. That way you can use your data display anywhere in your site and it's also ASP.NET compatible.
As Nat said - if all that is needed is to display some data from a database on a page - the DVWP is a great solution. Just open your page in SharePoint Designer, add the database connection, and drop the web part on your page. You can use any of the several pre-formatted layouts, or design/tweak your own so the data is displayed as you need.
Relatively straightforward, lots of HowTos online, and far faster/easier to setup than something like BDC.

How do modify a form on a sharepoint site?

I have a task that I need to perform for a friend as a favor, to modify some forms on a MOSS/Sharepoint site to add some javascript to each form for some SEO tracking purposes.
I've had a little bit of exposure to Sharepoint, but it is mostly by using the Sharepoint Designer 2007 tool.
I am able to navigate to the site, and I can see the content in Sharepoint Designer. However, I am not able to see the forms, and I'm a bit stuck.
Here is an example of a form that I need to modify:
http://www.MY_SITE_GOES_HERE.com/forms/covg_order.aspx
I've read a little online, but I'm stuck. I don't know if these are infopath forms or what. I just need to modify the forms.
Is there a simple answer to this problem? Or a good resource to get up to speed quickly for this task?
I'm not a sharepoint expert, so thank you in advance for answering a simple question.
While hardly the simplest approach, but since this is a developer site, I would recommend creating a DelegateControl to add to your site. Using DelegateControls has several benefits, for example:
the ability to selectively activate and deactivate the controls through features
no need to modify any out-of-the-box files which would break supportability
ability to output different content on a page-by-page basis
You can opt to use one of the DelegateControls of the default master pages if you need to deploy to an existing site based on one of the default site definitions. The AdditionalPageHead is a favorite among developers, as it allows multiple overrides to be active at the same time.
If you want to create your own master pages you can add DelegateControls as you like.
If you want to learn more about DelegateControls you can check out the first issue of Understanding SharePoint Journal (Disclaimer: I wrote that issue). Also, check out the MSDN article on How to customize a Delegate Control.
.b
you can also check PowerForms which is a silverlight webpart that fully customizes sharepoint forms. You can add business logic in forms using custom assemblies and a lot other advanced tasks. Give it a try, i think it will solve a lot of problems.
http://www.bpc.gr/powerforms
You have a couple of options here:
If you need to add a unique code, like Google analytics you should probably deploy your code to the master page.
In case you need to customize forms for lists you will have to do it with SharePoint designer. In that case you will find EditItem.aspx and NewItem.aspx with SharePoint Designer pages or any other custom page. Open SPD, locate your list, expand it, look for Forms subfolder and you will find all the forms there.
Microsoft Office SharePoint Designer is now free, as of 1-Apr-2009. It's a good tool, not only for modifying individual pages, but for entire sites.
