Question Denis Zaripov · Dec 10, 2017

Hi, I'm a student, weak programming. I ask for your help, I write a program in C #, there are two tables, but I do not understand how to organize the connection between them many to many. Table in DataGridView1 from DataSet1 on Form1 key connection in DataGridView1 from DataSet1 to Form3

I do this on Form1

private void dataGridView1_CellDoubleClick(object sender, DataGridViewCellEventArgs e) 
{
  if (e.RowIndex >= 0)
  {
    DataGridViewRow row = this.dataGridView1.Rows[e.RowIndex];
    Form1.IDfor3form = row.Cells[1].Value.ToString(); // By the Bilet column
    Form3 c = new Form3();
    c.Owner = this;
    c.Show();
  ​}
}

Question Alex Kogan · Nov 28, 2017

Hello,

I was wondering if there is a way to maybe temporarily alter the [Private] tag dynamically or any other way to run a Unit test against class method, which has been labeled as [Private]?

I mean, I understand there is a workaround to create a non private class method inside this class, which will in turn call this private method  and run a Unit test on the non private method, but I am looking for a way to do this without altering the original class.

Thank you,

Alex

Question Tom Philippi · Nov 28, 2017

When executing a business process I'd like to share the Login Token from an external system retrieved via one of my business operations across multiple process instances. This means I need to persist the token somewhere. What would be the best approach/pattern to implement this?

The primary idea I had was to store the token and a timestamp in a persistable object and then write a single method in the Business Operation that retrieves the token.

Question Brian Downing · Nov 15, 2017

Can anyone suggest suitable Cache ObjectScript syntax for open/use/read statements on a simple ms-dos text file.
I've tried various examples seen on the web but they appear to be implementation specific.
I used MSM MUMPS many years ago but am now retired & would like to write a few simple routines for my own amusement & mental challenge.
I am using the free Version of Cache (V 2017.1) on my Windows 10 PC. The installation file was CachePCkit_x64.exe
My apologies for this query being very basic.

Question Robert Harris · Nov 13, 2017

"Help me, Obi Wan Kenobi"?

I’ve hit the wall. I’m a one person shop who wants to start developing Cache on a mac using Eclipse/Atelier, after using Studio for the last 5 years. I’ve installed the 1.1 beta plugin, watched 6 or 7 videos from the September conference, tried several times to work through the cheat sheets, only to have connection issues or compilation issues, so at this point, I’m feeling very frustrated. The videos were interesting, but generally didn’t work as tutorials for fundamental programming operations, for me.

This should be an overview over a subject that pops up over several places in online documentation mostly as remarks and never as dedicated chapter.

Once upon a time ...  No it's not a fairy tale.
In the beginning of Caché (and before) you had your partition to run your code. Part of that partition was a space with all your local variables nicely sorted by %,A,..Z,a,...z

Greetings fellow Atelier users! To help new users get started, we are planning to make a list of video tutorials (e.g., how to create an Atelier project). The first one is "Introduction to Atelier", which is a brief tour of the Atelier user interface. We'd appreciate it if you could watch this video and let us know your comments. We'll be relying on your feedback to create more video tutorials to make it easier for new users to learn Atelier.

Please feel free to post your comments below. We look forward to hearing from you!

I'm extracting text from HTML (more on how - here), and after I extract text it has two problems:

  • Lot's of $c(10) control characters
  • Multiple whitespaces

I have a batch record mapper that reads a csv file and passes the message to a process that uses the EnsLib.MsgRouter.RoutingEngine and would like to pass the message to an operation that will output that as a XML file but so far been unlucky as the operation that I use , uses the EnsLib.EDI.XML.Operation.FileOperation which only works with the messages("BusinessOperation class for writing XML messages to a file. Works with XML messages of type EnsLib.EDI.XML.Document.

Question Mike Kadow · Oct 6, 2017

When starting a post, especially for the beginner there are a lot of buttons, check marks, icons etc. On some of them when you hover you get a very brief descriptions. In reading through some of the responses to the Developer Community Feedback there is a lot of good information.

Could one of the moderators, who know all the tricks put together a one or two page "cheat sheet?" or beginner guide?

This "Cheat Sheet" would be of great help!

I get the impression that there is a great push to encourage others to use the Developers Community.

Question Ricky Beca · Jul 31, 2017

Hello,

I come from a programming background, but haven't touched ObjectScript before my current job, so please forgive my ignorance.

Within an Ensemble system, I need to post some information to a RESTful web service. I'm just trying to figure out how to create a method which takes a simple message and posts this off to a RESTful web service?

Thanks in advance for any help.

Question Mihai Radu · Aug 31, 2017

I am trying to capture the write of a method to test the response in an unit test. I know everything works because one of my colleagues ran the code and did not froze on his machine.

I don't what is the cause of the freeze. I know that at line Use $io::("^"_$ZNAME) it stopes because i have put some write functions after every line in WriteCapture method and i only saw the first write function in terminal

I also used debug and in this case it didn't froze

PS: forgot to put the status in the XECUTE (vstrCommand , .

Question Russell Knight · Aug 31, 2017

Greetings,

Is it possible to save Cache code into a file and then run it via command line?  

IE:  csession [ini] -U [ini] /path/cacheCodeFile.?

What I need to do is run a Cache script from the Linux command line.  The script will navigate data to produce a file and then it will exit back to the command line.

Thanks in advance for everyone's time.

Question Eduard Lebedyuk · Aug 31, 2017

I need to check if one class is a subclass of another (either direct or indirect).

For example:

Class Package.ClassA Extends %Library.Persistent
{
}

Class Package.ClassB Extends Package.ClassA 
{
}

Class Package.ClassC Extends Package.ClassB
{
}

In this example Package.ClassC is a subclass of 3 classes: %Library.Persistent, Package.ClassA, Package.ClassB.

So any of these checks should return 1:

Write ##class(Some.System.Class).IsSubclass("Package.ClassC", "%Library.Persistent")
Write ##class(Some.System.Class).IsSubclass("Package.ClassC", " Package.ClassA")
Write ##class(Some.System.Class).IsSubclass("Package.ClassC", " Package.ClassB")
