Easy Promotion of Context Properties

As you’ll probably know, there are two types of properties in the context of a message: properties based on field values (MessageDataPropertyBase) and properties not based on fields (MessageContextPropertyBased). I’ll call the first ones Message Properties and the other ones Context Properties.

Message Properties based on message fields are automatically written and promoted into message context by BizTalk.
Context Properties not based on message fields can be assigned inside an orchestration using the expression Message(Property) = “value”;
One of the most interesting stuff about Context Properties is that are not tied to a concrete schema, so they can be used regardless the message type. A sample of a system context property is FILE.ReceivedFilename.

The problem of promoting context properties:
When you create a context property, not based on a message field, and you assign a value inside an orchestration, it is written, but not promoted. What does it means? it means that you cannot route the message based on this property.
Some days ago I had the situation where needed exactly this: content based routing based on a custom context property that had a value calculated inside an orchestration.

The trick:
In my case, the pipeline solution is not an option, since I’m routing between orchestrations via Direct Port Binding. Also, coding a custom component to promote a property seems to complex for me…
Somebody told me a good trick to promote context properties inside an orchestration, easy and direct:
Create a CorrelationSet based on the property.
Even if you are not going to use it, when you initialize a CorrelationSet, the Orchestration engine makes the promotion of the properties involved, since correlation is just an special kind of routing.

So now I have some dummy CorrelationSets, that I call Promote_CorrelationSet

nice and easy! :-)

Calling .Net assembly from Biztalk Orchestration: Where to put Config

BizTalk uses its own configuration file called btsntsvc.exe.config which is in the BizTalk program files directory. You can add your configuration sections into this file and then bounce the biztalk host instances to pick up the changes.

HOWEVER, this is not good practice. It's OK to do this when you have only a single BizTalk app server but if you need to scale out suddenly you have multiple config files to maintain.

The recommended approach is to use SSO to store app-specific Config data, since it's BizTalk's Config storage solution and therefore always available. I always use this method and have never had any problems (although there is some overhead associated with development and management).

How to save password for WCF Adapter in BizTalk binding file

Generally, it is not recommended to store passwords in the binding file and by default BizTalk administration UI clears it out when exporting binding to the xml file. But in development environment where you have automated continuous integration build and deployment not having password in the binding file will prevent application from starting and CI process fail. It can become tedious in staging deployments (TEST, UAT) as well, especially if you have multiple endpoints that use accounts with passwords. In such cases, having password for development account (hopefully not the same as production) in binding file can make life easier.

To do that, export binding file after application is fully configured. Open it and locate section(s) with configuration for the ports/locations of interest. For example for the WCF receive location it will be in:

<ReceiveLocationTransportTypeData><CustomProps>...</CustomProps></ReceiveLocationTransportTypeData>

Find emtpy password tag in this section that will look like:

"& lt;Password vt="1"/& gt;"

Change it to enclose you password value and vt attribute value to "8":

"& lt;Password vt="8"& gt;MyPassword& lt;/Password& gt;"

Save and use this binding for an automated deployment script.

XPath Inside Orchestrations in BizTalk

Working with XPath inside Orchestrations is a powerful and simple feature of BizTalk.

The help guide does a good job describing the process (under Using XPath in Message Assignment).

XPath queries can only be done against a Message and the results can be set to a Message, XML Document or other orchestration variables. XPath queries can also be executed against untyped messages. That is, a Message that is of type System.Xml.XmlDocument.

CRITICAL: BizTalk xpath can be used to both read values and set values inside your Message. To set values in message, we need to be inside a Message Construct shape.

Here are some of the things which we can do with xpath and how to do them:

- Set a single values inside a Message using xpath
   xpath(SingleXML, "//LineTotal") = nLineTotal;

- Extract a single piece of data out of a Message
  sCustomer = xpath(InXML,"string(//Customer)");

- Extract a single node out of a large XML Document and assign it to a message or  variable
 sXPath = System.String.Format("//Item[{0}]",nCount);
 xDoc = xpath(InXML, sXPath);

- Count the number of nodes or occurrences of something inside your message
  nNumberItems = System.Convert.ToInt32(xpath(InXML, "count(//Item)"));

A great resource for xpath functions and expressions is the W3Schools.

cell phone Screen stays off throughout the call

Last week I drop my Cell Phone (Dell Venue Pro) and broke front glass. I order front glass screen from ebay and fix cell phone at home (Thanks to youtube).

Everything worked fine but I was facing issue related to -Screen stays off while making calls and after receiving calls (the screen turns off n stay that way till call ends). this was very frustrating as cannot do any activity after i dial number or receive call.

Thought something is obscuring the Light sensor or promimity Sensor, because during a call the screen being off is a feature.

You can fix it though in the EM app. You can adjust the sensor readings and the phone will function like normal. (IF NOT  it might be hardware defect). But i would suggest its worth trying.

1) Get the EM app, if you dont have it dial ##634# into the dialer

2) Get into the advanced menu by double tapping the black area and typing in "qwertyuiop"

3) Select "RD test", now enter *#6336# in the box that pops up.

4) Select "Sensors", and the "Proximity Sensor Config"

5) Set the following to these:

LED strength - 1
Diode select - 2
Pulse Count - 43

6) Hit set and then you are good to go!

FYI might needs to have this put in again everytime we reboot the phone, most other cell phones saves it.

ALTERNATE FIX: Fixed it by doing a calibration on the same prox sensor settings screen, but with my hand over the sensor to calibrate it to darkness. Then the sensor output started reading something other than 1023 (around 320 when light and 840 when dark) and it started working fine. all in one reading should be other than 1023. for me Pulse Count - 1 worked.

Not Using "http://namespace#root" as BizTalk Message Type

Not Using "http://namespace#root" as BizTalk Message Type

This has come up twice for me in the past week: once while reading the tech review comments on my own book (due out in April), and again while I was tech reviewing another BizTalk book (due out in July).  That is, we presumptively say that the BizTalk “message type” always equals http://namespace#root when that’s not necessarily true.  Let’s look at two cases demonstrated here.

This first simple case looks at a situation where an XML schema actually has no namespace.  Consider this schema

Perfectly fine schema, no target namespace.  I’ve gone ahead and created another schema (with namespace) and mapped the no-namespace schema to the namespace schema.  After I deploy this solution and create the necessary ports to both pick up and drop off the message, I can stop the send port and observe the context properties of the inbound message.

Notice that my message type is set to ReturnRequest which is the name of the root node of my schema.  Obviously, no namespace is required here.  If I throw my map on the send port, I can also see that the source schema is successfully found and used when mapping to my destination format.

So, for case #1, you can have schemas with no namespace, and the message type for that message traveling through BizTalk is in no worse shape.

Get Localize DAte format

    // Displays dt, formatted using the ShortDatePattern
    // and the CurrentThread.CurrentCulture.
