The power went out for a short while today. Though I have no idea what stroke of luck caused this to happen on a 70 degree sunny day, I took great advantage of it and planted peas in the veggie garden bed. Most things can't be planted until after memorial day. But to sate my need to get gardening, I have seeds for a bunch of things that can get started early.

ok I retitled the post - didn't want to trick anyone into reading about my garden ....<g>

Though I have the necessary permissions for using SqlDependency almost memorized (as well as documented in my presentations and my new CoDe Mag article on Query Notification), I tend to forget that when using the lower level SqlNotificationRequest, that you need permissions to send and receive on your custom services and queues.

Here's how to do that and here is the MSDN Documentation on the same.

In this example, the ASPNET account is the one for IIS5 that I have set up in my SQL Server. Use whichever account is going to be accessing the services and queues.

GRANT RECEIVE ON MyNotifQueue TO ASPNET

GRANT SEND ON SERVICE::[MyNotifService] TO [ASPNET]

Having spoken a few times over the years at the one of the Poughkeepsie NY ACM groups, I am on their mailing list. I got a good laugh from the recent mailing announcing a talk about Image Storage ex-IBM engineer (that describes most of the members of the chapter) who has an I.T. support business. In his business description, he says:

To keep from being swamped with more and more business, Jerry has adopted a new slogan:  Highest Priced Computer Service in Town.

The TabletPC Hands on Labs were very popular at DevConnections. I think I heard that over 600 people did the labs. Upon completion of the HOLs, the attendees were given a bright orange Mobile PC baseball cap. Throughout the conference, 3 attendees wearing those hats won a new Toshiba M400 Mobile PC (you know, a tablet). Lora Heiny has a lot of great pictures of the thrilled recipients here.

You can imagine that every time attendees were in one big room, for example at breakfast or lunch, it was a sea of orange, as they were all wearing the hats in hopes of winning the M400.

But even after all of the M400's had been given away, people were still wearing the hats. They were kind of cool. At the closing session, where perhaps 1,000 of the attendees were all seated, I took this short video to show the sea of orange hats.

It is only 12 seconds long. The AVI version from my camera is 25 MB and the choppier WMV file is only 2.9 megs.

As I was doing the last section of my "5 Supposedly Scary Things in .NET" talk last night at the Vermont.NET user group, I came to the slide with the Permission attributes examples to either Request, Demand or Assert permissions. I had decided to try to explain these (very high level) as they had always completely mystified me. Although I have given this talk before, I had a sudden epiphany for a new analogy for the demanding and asserting permissions - purchasing beer. [Read more ...]

I'll be doing a talk entitled "Five Supposedly Scary things about .NET" at Vermont.NET this evening.

The talk covers the following daunting topics on a high level

1. Declarative Attributes
2. Reflection
3. Delegate
4. Threading
5. Code Access Security

I'll be raffling off the last of the launch copies of Visual Studio 2005 PRO and SQL SErver 2005 Standard.

After I did this talk at DevConnections last week, an attendee told me that he had been trying to solve some problems with an app and hadn't looked at any of these technologies becuase they seemed over his head. He was very excited because he realized that he could solve these problems using some of the stuff covered in the talk and was looking forward to learning more and leveraging them. That is exactly why I did the talk. I hope to inspire others as well.

CoDe Magazine sends a pile of issues for the VTdotNET user group every month. I got the box before I left for DevConnections and set it aside, only opening it this morning in prep for tonight's user group meeting. I didn't realize that the Query Notification article and the opinion piece I wrote for them had already been printed, but there they were. It's the May/June issue but is not online yet. In addition to my articles, there is the first of the WCF series articles in there (yay!!!) by Juval Lowy and one on Transactions in ADO.NET by Sahil Malik (yay!). And of course (as always) bunches of other great articles and columns.

Lori McKinney sent me an email in response to my Winforms hosted in i.e. post, pointing out the I.E. update that  caters to the EOLAS lawsuit.This hadn't caught my eye before. The update forces users to "activate" ActiveX controls (such as Flash) hosted on a web page. Here is the official article on how that affects our websites. I also found a blog post by Steve Smith and another by Matt Watson with discusson on workarounds.

I installed the update this morning from Windows Update to see  how it affected my ink-enabled winforms controls that are hosted in a web page (eg the Doodling website). Without any of the scripting workarounds, the effect is not really bad at first. Just by placing the cursor over the control area, I get the popup that says "click to activate and use this control." Click and I'm instantly inking. But it doesn't remember! I have to do it every time I ope the page in a new i.e. session. This is with Disable Script Debugging checked. If I refresh the page, I get a different message, "press spacebar or enter to activate the control." But just clicking still works. Odd.

Okay so that was testing on my non-tablet with a mouse. With the tablet and stylus, luckily I don't really need to tap and THEN draw. Doing that gives me an inky dot where I tapped. But I can actually just ignore the message and start drawing and it works. But this means, I will have to explain this on my website. Hmmm. Maybe I'll have to check into the scripting after all.

So the known issue is with this thing unchecked - as all good web developers have it set. I didn't experience anything different. I'll keep playing with it.

I have spent most of the day trying to understand some bizarre behavior in VS2005 with ink on the web apps. The issue is not related to the inkable control per se, but the Windows Forms control hosted on a web page.

When I compile the Window Control Library into a dll for the first time, add it into the web project, then embed into the html as an <OBJECT> it works fine. But if I recompile the dll and re-add it tothe project, the control does not display. I get the standard "image not found" graphic that you would get on any web page displaying a jpg where the jpg is not available.

After many hours, I discovered the solution, which I am leaning towards thinking is only related to working on the development machine - if I change the name of the output assembly, then add that new assembly to the web project and modify the object tags accordingly, it works just fine.

This really made me nuts and I think I spent 6 hours trying to figure out "what I was doing wrong". Of course, I'm not done with this yet... as this is not good behavior! I'll have to find out if there is a logical reason for this, but it will be one more hindrance to people using ink on the web if they are developingin VS2005.

I have an application with lots of projects in it.The main project, which compiles to the EXE has references to two Janus assemblies and to one of my own assemblies (the dll, not the project). Additionally, I have about 15 assemblies that use these components and point to their dll's in the same location as the main exe does. Somehow, something got out of whack and in design mode the main exe couldn't "find" these 3 assemblies. I got that fixed and at the same time had to make some different changes to two of the other assemblies. After doing my update via clickonce, I couldn't load these two assemblies in the application on client machines. I did a lot of recompiling and redeploying of specific assemblies so that I could continue with my minimal impact ClickOnce update.This means that I don't republish and redploy the ENTIRE application, but can just move only the assembies I need to the webserver and recreate the manifests there. (I need to write an article on this).

When I tried to access the functions that loaded these assemblies, there was an error complaining about matching assemblies listed in the manifest.

"The located assesmbly's manifest definition does not match the assembly reference"

When I opened up these projects in VS2005 and looked at the references, those three assemblies had this "<system could not find the reference specified>" in the value where the path should have been.

So, I had to load up every one of these projects and in each one, remove the existing refs to those 3 assembiles and re-add them in.

Then I rebuilt the entire solution and had to run the full publish utility on my development machine and redeploy the entire application to the web server - a two part process. Two-part, because the dynamic assemblies do not get picked up by the publish tool. I have to deploy the results of the publish, then copy that folder into a new folder (next version number), add all of the dynamic dll's, then rebuild the manifests. (That's part of the trick I will write about in the aforementioned article.) The whole app is about 11MB. Copying this over VPN with 350K upload speed takes longer than I have patience for, but that's life.

Nevertheless, after a lot of copying, pastng, manifest buildng adn testing, I was able to get the whole re-jiggered app deployed without requiring the dreaded un-install. The end-users won't even notice a thing tomorrow morning when they get back to work.

Ahh, I'm a day late and a dollar short. Yesterday the PAG Team announced Service BAT - Service Baseline Architecture Toolkit - that will guide and help you implement WCF and ASMX services. They have had a bunch of plumbers helping them out including Christian Weyer and Pablo Cibraro. I can't wait to get my hands on it. This type of tooling will help take another layer of fear (and unintentional bad design) allowing WCF to be accessible to a lot more people.

Here's Jason Blogg's announcement.

Edward Bakker has some good details.

(note: for those of you who need this clarification - eg the anonymous commentor who gave me the big lecture - the title and the last sentences of this post are intended to be sarcastic. Sheesh.)

In my talk on Preparing WSE3 Web Services for WCF at DevConnections, I was asked the dreaded question: do these work on the compact framework?

Nobody likes to get this question, because the answer is just way too embarrassing.

The answer is "No".

This has been the cause a lot of ruffled feathers in the CF and Web Services community. Casey Chesnut , our resident genius, even wrote his own implementations: cfWSE and cfWSE2.

The last version of the WCF story that I heard was that R1 will not have it, but R2 will. The WCF footprint is small which will help enormously. But R2.

To top it off, though I don't have a PPC and didn't see this myself, I am astonished to learn through Softwaremaker, yet another place where security has been set aside: Passport logins. On the web, we get a login and a masked password, along with options to remember the login, password or both. Not only are those options gone with the PPC interface, but the password is not masked! Hello?

I suppose that it is another indication that people who use PPCs or write applications for them, are just not doing anything important enough to require security. I suppose.

Pablo Cibraro answers gazillions of questions in the WSE newsgroup. He also follows up with a lot of them too. I am extremely happy to see that his generosity with his time and his knowledge has been recognized by Microsoft. His award is in Connected Systems Developer. He is also doing a lot of work with WCF.
