How to get calling menu name in extensions Dynamics 365 for finance and operations

by

Today is small tip, Many times, we have to took decision based on the name of menu  on which form is called. By getting menu name we can use same form for different purposes.  We can write logic based on current form called from which menu item.

Following is the code snippet helps you to achieve this.

[FormEventHandler(formStr(LogisticsContactInfoGrid), FormEventType::Initialized)]
    public static void LogisticsContactInfoGrid_OnInitialized(xFormRun sender, FormEventArgs e)
    {
        FormRun formRun = sender;
        
        if (formRun.args().menuItemName() == "CustomerLogisticsContactInfoGrid")
        {
            FormDataSource      LogisticsElectronicAddress_ds =formRun.dataSource("LogisticsElectronicAddress");
            LogisticsElectronicAddress_ds.InsertIfEmpty(true);
            LogisticsElectronicAddress_ds.object(fieldNum(LogisticsElectronicAddress, Locator)).mandatory(true);
        }

Operation could not completed parameter is incorrect D365 for finance and operations.

by

Aahaaaa, just started development, one table, some edts and a form, as I tried to compile , I found the Error

” Operation could not completed parameter is incorrect”.

Machine generated alternative text: Microsoft Visual Studio The operation could not be completed. The parameter is incorrect. OK x

Interestingly, the old trick, run visual studio as administrator still works here.

So I saved the project and run the Visual studio by right click on visual studio Icon and select the run at Administrator.

Image stored in Dynamics Ax 2012 tables

by

In dynamics Ax 2012, You can read image from physical path and stored in database as follow

BinData binData = new BinData();
str extention, path, nameOfFile;
container imageContainer;
str imageFilePathName;
imageFilePathName=”C:\\abc\\ali.jpg”;
// if ( WinAPI::fileExists(imageFilePathName))
{
binData.loadFile(imageFilePathName);
imageContainer = binData.getData();
table.Person = _Party.RecId;
table.Image = imageContainer;
table.insert();

}

This code runs both for server side and client side. At server side execution table use winserverapi::FileExists

How to Send File to MSMQ Using C#

by

During the testing of BizTalk application, which read data from MSMQ. I have to write small C# routine, this routine send data to MSMQ.  If you have no knowledge about MSMQ, Please read My Post on this here.
http://www.biztalkhq.com/what-is-msmq-and-how-to-configure-it-on-windows-7/

 

To Send File on MSMQ you have to include the dll System.Messaging in your C# or Vb.net application. To Simplest code is as follow.

 

public void FileToMSMQ(string FilePath, string MsmqName)

{

//FilePath =@”e:test.xml”;

//MsmqName= @".private$testQue";

System.Messaging.MessageQueue _TheQueue = new System.Messaging.MessageQueue(MsmqName);

System.IO.FileStream _FileStream = new System.IO.FileStream(FilePath, System.IO.FileMode.Open);

Message _Message = new Message();

_Message.BodyStream = _FileStream;

_Message.Label = System.IO.Path.GetFileName(FilePath);

_Message.Priority = MessagePriority.Normal;

_TheQueue.Send(_Message);

}
You can down sample code from here

 

 

 

 

Generic fault message exception handling

by

 

In my current project, there are 50 operations on each port. It is very difficult and time consuming to create fault on every port operation and then add exception handler for every fault message.  This solution is not so comprehensive that if fault message is of different type what you made on each port

For example I selected “BTS.Soap_envelope_1__1.Fault on each operation,

than orchestration goes in suspended mode and process left uncompleted.

After too much search if found following exception type.

Microsoft.XLANGs.BaseTypes.UnexpectedMessageTypeException

 

Its works wonder if any fault message return my orchestration process is not break.

 

Pros: Normal exception caught and Orchestration completes its process.

Con: suspended instance of orchestration still visible at BizTalk admin with message “The instance completed without consuming all of its messages. The instance and its unconsumed messages have been suspended.”
