Tech Off - Using UIPAB Wisely

MonkeyMon — Thu, 13 May 2004 14:19:34 GMT

Welp,

GotDotNEt workspace is down.

It is presently beyond my control for any of the following reasons..pick one:
1. Censorship - nothing on site is anything but G-rated.
2. MS Servers are overloaded - not a good advertisement for MS software.
3. GotDotNet site itself is buggy - I could get to other workspaces.
4. As owner of site i screwed up the configuration somehow - possible. I don't work at Microsoft so I'm boring and fallible.

Anyhoo - hopes that the site is back up soon.....

Please come on over to my new workspace for a simple ASP.NET/VB.NET sample using the UIPAB.

http://www.gotdotnet.com/Community/Workspaces/workspace.aspx?id=a9ab4d8d-6a35-456e-b70d-0e40cbbae8d5

There's a discussion newsgroup there and it'll be active. See you soon. Also downloadable sample that works and is simple to follow.

Tech Off - Using UIPAB Wisely

I've finally got a web sample of mine configured to at least navigate using ther UIPAB.

The next challenge is to figure out how to take care of traditional forms control operations. Do we try to include all these methods in the controller class?? or do we continue to call them in the code behind?

Seems like most of the samples from MS are one task, one screen type architecture, whereas in the real world, the ASP.NET screen does a lot of work simply posting back to itself.....trying to grasp this new paradigm.

Any ideas, thoughts, or grotesque noises??

yes, that document gave me a headache 3 out of 5 days last week.

I'm at the point now that I'm just trying to throw together a working model using the UIPBA.

I've done everything the way i understand it but still getting errors within the UIPAB code which i've tried to figure out what part of my code is raising the error....

I feel like i'm close to getting this thiong going. I use VB.NET so some of the UIPAB is not a readable as I'd like for source perusal....

Thanks

Karim,

All this posting to myself is blurring my vision. But perhaps I can help others through my quest.

Apparently only two people on the face of the Earth are actually trying to use the UIP. And we're both a tad frustrated with the lack of response.

I'm thinking that the UIP is a stop gap unsupported crutch for use until VS2005 ships - everything will change then right?

is this mike on?

My name is Harry Simpson. I've been doing ASP.NET since the original PDC release. At that time i was a developer/consultant for Quilogy (SoluTech). I started my own company MicroWorks back in 1994. My first website went up in 1995. OVer the next 5 years i produce 5 commercial software products, mostly engineering apps. I'm a member and past BOD of the Association of Shareware Professionals.

Presently do VB.NET, ASP.NET for a medical software company. I'm an MCSD and let my MCT run out (MS wanted $400 and i was unemployed at the time....)

I've been giving myself headaches on a daily basis trying to wrap my brain around the UI Process Application Block and was hoping for a little help from Channel9.

For fun and work i also write apps for the Pocket PC. USe to write Palm apps too.

I go home to a wonderful woman (2nd anniversary this month) who buys me beer and wants power tools for HER birthday......the good life!

The site looks great and my hopes are high.

Tech Off - UIP Application Block

MonkeyMon — Thu, 06 May 2004 20:57:28 GMT

If i didn't respond to my post, who would. Where's the Microsoft Love for Developers here?

I'm trying to build the most simple implementation of the UIP block in a test web app. One screen....i can't get the one screen to even display - of course i'm inheriting the aspx page from WebFormView.

I've got all the pieces in place but run the app and get an error within the block class:

private SessionMoniker GetSessionMoniker()
Line 114: {
Line 115: SessionMoniker sessionMoniker = SessionMoniker.GetFromSession( new Guid( Session[CurrentTaskKey].ToString() ) );
Line 116: return sessionMoniker;
Line 117: }

I'd really like to understand this block and how to use it before trashing it in favor of anything else.

I've tried the newsgroups but get about the same response there as here so far. I guess this may be another instance of something built but never really ever used in real practice eh?

Thanks for weathering the mild rant.....

Is there anyone at Channel9 that could direct me to resources for the User Interface Application Block?

Also, that'd be a great video to interview the folks that created it and talk about the uses, applications, etc.

Thanks

Be careful with objects in .NET passing ByVal. Many objects are passed ByRef even with the ByVal declaration since a pointer only is passed. In several examples from MS, they actually populate datasets passed in ByVal in Sub Procedures.....took me a while to figure out what was going on cause I'd prefer to always use a function if i'm grabbing data if possible.

Thanks,

I'd seen this but was turned off by the C# but heck if the logic is there i can translate.

Grabbed both and will have the articles for lunch.

Any Channel 9ers responsible for the UIP block documentation? Could we get more pictures and 5-1 surround sound next iteration....seriously, is there going to be a webcast or at least a little more forgiving narrative accompanying this block. I'd really like to use it but am trying to get a better understanding of the why and how to use.

Here's some code i use in an asp.net app i wrote:
