Hi all

A couple of months ago, while trying to solve the If-Then-Else issue within a map in a nice way, a fellow BizTalk MVP suggested to me that I could just have the script inside a custom scripting functoid and then copy the script from custom scripting functoid to custom scripting functoid.

Naturally (as I assumed it was, back then) I told him that this was impossible, because BizTalk wouldn't let me have two custom scripting functoids which contains the same method, ie. the two methods have the same signature.

"Sure you can", he replied.... So I had to check it out... I fired up my BizTalk 2006 R2 virtual machine, and sure enough: He was right. I was in chock, because I was totally sure i was right. so I fired up a BizTalk 2006 virtual machine and again; He was right and I was wrong.

Now... those who know me will know that when I am convinced I am right, I will usually go to great lengths to prove it So I stepped down a version and tried BizTalk 2004. Again no luck.

But FINALLY, when trying it on BizTalk 2002, it turned out that I was right. Back in BizTalk 2002, scripts were in VBScript and here you can not have multiple custom scripting functoids with methods with the same signature. In versions after BizTalk 2002, the compiler will collapse those methods into one, but in BizTalk 2000 and 2002, this is not done, and therefore an error occurs.

So all in all, I discovered this limitation back in 2003 and never questioned it again since. So let this be a lesson to all (especially me, because I always think I am right ) - that sometimes we need to reevaluate what we think we know.

Hopefully this post will:

1. encourage people to reevaluate opinions and knowledge
2. inform others like me, who thinks that you cannot have the same method signature twice in a map, that this is wrong

Hi all

So, I have written two previous posts about how to solve the If-Then-Else problem in a map. The first post discussed the way to use built-in functoids to solve the issue. The second post discussed the issues I had creating a custom functoid to do the job.

Well, I now have a new way of doing it, which is not just one functoid, but still it's prettier than what I can do with the built-in functoids.

Basically, as discussed in my post about the issues with the different functoid categories, a functoid that is in the String category cannot accept a logical functoid as input. A scripting functoid can accept a logical functoid as input, but I can't create a custom scripting functoid where I decide what script to appear inside the scripting functoid at design time.

So the solution I am describing in this post is a combination of the two.

This screenshot describes a map that solves the If-Then-Else problem:

The blue functoid with the crappy icon is programmed by myself. It is a simple functoid, which takes in three parameters, which are all strings. First, it tries to convert the first parameter to a boolean. If this fails, a "false" is assumed. Then, if the boolean was true, the second parameter is returned and if it was false, the third parameter is returned.

Now, since a string functoid cannot take a logical functoid as an input, I use a custom scripting functoid that is very simple:

public string Same(string str)
{
return str;
}

Which is really annoying to have to do, since... well... I take in a string and return the exact same string. Oh well...

You can find my functoid and the project that uses it as file downloads at the bottom of this post. Note, that the functoid library contains a whole bunch of functoids, of which only one is relevant. The library contains all the functoids I built trying to solve the If-Then-Else issue. The only needed functoid will be included in my downloadable functoid library at a later point.

Now, the advantages of this solution is, that it only requires three functoids all together. The best I could do with the built-in functoids were four, and five were sometimes the prettiest solution.

Hi all

So, a colleague of mine is integrating with AS/400 and this system seems to be sending all strings as all-uppercase. So a company name might look like this: "JANS SUPERCOMPANY A/S". This really isn't what he wants output in the end, so I have built a functoid and added it to my downloadable collection, which converts the "JANS SUPERCOMPANY A/S" into "Jans Supercompany A/S". It has an optional set of strings that are not to be messed with

Examples of output from the functoid. The second parameter is optional.

As always, you can download the functoid at http://www.eliasen.eu/DownloadSoftware.aspx - where you can also download the documentation.

Hi all

After I gave a BizTalk presentation at Aalborg .NET User Group I got a message from Søren Spelling Lund from Århus .NET User Group who wanted to interview me about BizTalk for a Podcast. Naturally, I accepted, and the result can be found here.

Only in Danish, I am afraid.

Hi all

I have added a new program to be downloaded for free from http://www.eliasen.eu/DownloadSoftware.aspx. This time it is a program to help you do two things:

1. Check an XML file to see if it is well formed
2. Validate an XML file against an XSD schema

I have had the need for a small utility to do this several times, in case a customer has some XML, and they want to know if the XML is even valid. The check for well formed-ness can be done by simply opening the file in Internet Explorer, but that is just soooo slow for large files. I tried a 70MB XML file once. It took IE a couple of hours to open it and tell me what was wrong with the XML. My utility did it in a few seconds.

So, use it if you want...

Hi all

Today, I took the 70-241 exam in BizTalk 2006 R2.

I passed, and am now MCTS: BizTalk Server 2006 R2

I have now passed the exams in BizTalk 2000, BizTalk 2004, BizTalk 2006 and BizTalk 2006 R2. Anyone else out there who has done this?

Hi all

At Logica we often participate in different events where employees compete to see who rides their bike more often to work, who walks the most steps in a month, and so on. After a month of competition, we end up with a spreadsheet, where I may have walked 180.000 steps, but my colleague Henrik only walked 78.000 steps (He is kind of a wimp )

So lets say that we want to give a prize to one of us, and Henrik should have a chance of 78000/(78000+180000) (30,23%) of winning and I should have a chance of 180000/(78000+180000) (69,77%) of winning. As the number of points and the number of contestants get bigger, this becomes increasingly difficult to manage.

Therefore, I have written a small winforms program, that helps you manage this. You can add as many contestants as you like, and give them points. If you are only interested in a "normal" draw, you can just give all contestants one point.

Screen shot:

The program not only does the draw, it will also:

• Give you an overview of the contestants, their points and their chance of winning, which is dynamically updated each time a contestant is added
• Give you the opportunity to simulate any number of draws, to ensure that the program is random. When doing the simulation, the percentage of wins by each contestant is shown next to the chance of winning, so they can be compared.

I will gladly take comments, bug reports, suggestions, postcards, et cetera

The documentation can be found at http://www.eliasen.eu/DownloadSoftware.aspx#documentation and the program can be downloaded at http://www.eliasen.eu/DownloadSoftware.aspx#winform.

I hope this comes in handy to someone.

Hi all

I am using http://www.last.fm to keep track of what I listen to, and to get inspired to listen to some new music that I didn't know I liked.

You can find my profile at http://www.last.fm/user/eliasen and you can find information about an excellent Danish band Baal at http://www.last.fm/music/Baal. Please note, though, that I listen to the Danish band Baal, and not the Japanese band that unfortunately shares the band name Baal with the Danish band.

Anyway, the point of this blog post is, that it seems that I am currently the top listener of Baal:

This means that I listen to more Baal than all that listen to either the Danish or the Japanese band...

I know... Get a life, damn it!

Baal have a web site at http://www.baalworld.com - try it!

Hi all

It is time for the third posting in my series about using BizTalk to integrate to Excel spreadsheets. My first two postings are here (Installation) and here (The schema generation wizard).

This third posting is a talk about the runtime, and how it works.

The setup

To start out, I have done a simple test, and you can find my project

It has a simple spreadsheet and a schema for this spreadsheet (both are described in my previous post) and the setup basically just has a FILE Receive Location and a send port with a filter that takes everything from the Receive Port the Receive Location belongs to. My aim is to see how fast the Spread Disassembler is.

First, a short description of my setup:

My BizTalk installation is in a Microsoft Virtual PC 2007 virtual machine.

The host machine is a Hewlett Packard 8710w laptop with an Intel Core Duo T7700 2,4GHz CPU, 2GB of RAM and Windows XP Professional Service Pack 3 and completely updated as of 7'th December 2008.

The guest system is a virtual machine which has one 2,4GHz CPU, 1GB RAM and Microsoft Windows Server 2003 R2 Enterprise Edition SP2 - also completely updated as of 7'th December 2008.

The test

I created 999 copies of the same spreadsheet and moved them into a folder watched by the receive location. They were read, transformed into XML, and output into the output folder in 3:19 minutes. This is an average of 5 spreadsheets per second.

This took me by surprise - I had expected it to be faster. So I decided to do things more academic than looking at the time stamps of the output files. After all, there are PLENTY of functionality that could be the time consumer. So I created a BAM Activity and View, tracking when my Receive Port starts and when it ends.

A table showing the average processing time can be seen here:

So it is pretty clear, that performance drops drastically when the load increases. I do not blame this on the Spread Disassembler, though. Since this is a virtual PC, with SQL Server on the same box as BizTalk, the mere I/O operations when writing all the output files to the hard drive conflicts with the I/O operations of BizTalk using the MessageBox. I find this a much more likely issue for the drop in performance than that the disassembler should get slower just because more messages come in.

So, to sum up, it seems that the Spread Disassembler can take a pretty heavy load - Up to 2643 messages per minute (44 messages per second). This is given less than ideal operating and hardware conditions, but optimal conditions with regards to the BizTalk Server not doing anything else at the time.

Maybe in a later post I will take a look at more complex spreadsheets/schemas and also test the performance of the assembler.

Hi all

The company hosting the eliasen.dk domain went bancrupt last friday (19'th December 2008), and I only just found out this morning (Monday the 22'nd December).

So basically, everything since my last backup (27'th November 2008) is gone!

Right now, I am trying to setup the blog on the new server and trying to see if I can repost the blog posts I have written since the 27'th November.
