General Board / Re: Addition/subtraction in DLL templates ?
« on: February 27, 2017, 12:44:05 pm »
Hi Qal,

There are actually function macros available in the code gen / transformation templates for MATH_ADD, MATH_SUB and MATH_MULT.  Unfortunately they don't seem to be documented though.  We will look into getting the help updated.

MATH_ADD(x, y)
Returns the value of x+y.

Returns the value of x*y.

MATH_SUB(x, y)
Returns the value of x-y.

Note: x and y for above parameters can be passed as either numerals or strings.  E.g. %MATH_ADD("10", "2")% returns 12.

Automation Interface, Add-Ins and Tools / Re: DOORS MDG

Something I'm not getting trying to read the posts is whether the MDG link connects directly to the DOORS server, or through a local DOORS client. [...] Does using the MDG require a local DOORS client to work?

Yes, MDG Link for DOORS requires the DOORS Client.  Information is pulled via the API of the DOORS Client, it does not connect directly to the DOORS database.  To connect your DOORS module from EA, you need to have the DOORS client open and connected to your database, and have the specific module open that you want to connect with.

General Board / Re: Webinars

There were also webinars in December and January.  You can find them here:

What are the strings you are returning for your menu items (particularly the root menu)?  Do any of them contain a hyphen at the beginning (indicating a submenu) followed by one or more spaces?

For example: We had a report from another user who was returning a string like "- My Menu" for their root menu.  For some reason the space following the hyphen was getting stripped by EA, which then failed on later comparison, resulting in no menu items getting displayed under EA 13.  Deleting the space after the hyphen resolved the problem.

If you are still having problems, please provide a copy of the code for your EA_GetMenuItems method so we can take a closer look.

Just to be clear though, the upcoming webinar is primarily focused on installation of Enterprise Architect itself under WINE.  I don't think it will be covering installation of keystore or cloud services (at least not as far as I know).

Root (Model) packages are a special case.  They do not have an associated Element class and will not have Tagged Values either.

Bugs and Issues / Re: All Add-ins is missing

We have seen some strange problems like this when someone (or something?) has set a default value at the top of the HKEY_CURRENT_USER registry hive.

We have seen cases with other customers where something has set a value there it causes problems when EA tries to query the [HKEY_CURRENT_USER\Software\Sparx Systems\EAAddins] key.  For some reason when the key being requested does not exist, the Windows API returns whatever value was set at the top of HKEY_CURRENT_USER instead.

Try selecting the (Default) value directly under HKEY_CURRENT_USER, then Right-click | Delete it.  (not the HKEY_CURRENT_USER key itself, just it's default value).

The (Default) value should say (value not set) next to it.  If you see a different value, or a blank value, delete the (default).

Usual caveats apply here - be very careful when messing about in the registry or you may kill your Windows installation.

General Board / Re: Is there a VS integration with Cloud Services
« on: October 17, 2016, 12:23:42 pm »
In Enterprise Architect, connect to your cloud server and then save a Shortcut EAP file to this repository.

In Visual Studio, select Attach Existing Model and then browse to this shortcut EAP file.

General Board / Re: EA upgrade to 13 - system requirements
« on: October 14, 2016, 11:18:36 am »
Hi Carsten,

Yes, EA 13 is supported on WINE and actually contains many improvements in regards to Linux/Mac compatibility.  See:

The installation process should still be quite similar to EA 8, except that EA installers are now distributed as a .MSI file rather than a .EXE, so the install command is slightly different now.  The page you mention was recently revised to hopefully make the entire installation process more clear.

General Board / Re: MDG SYSML Installation
« on: September 20, 2016, 10:11:20 am »
The SysML add-in is obsolete and should not be installed.  SysML functionality is now built-in with Enterprise Architect and should automatically be available when an appropriate license key is detected.  (E.g. EA Ultimate, EA Systems Engineering, or a combination of EA Corporate/Professional + MDG Technology for SysML license keys).

General Board / Re: EA 11 and Anniversary Edition Update
« on: September 15, 2016, 09:33:50 am »
Official support for Windows 10 was first added in EA 12.1 (Build 1224).  EA 11 is not supported for Windows 10.

General Board / Re: Drawing a square on a diagram
« on: September 01, 2016, 09:47:15 am »
y-position goes to negative, not positive.
Top and Bottom when stored in the database will be negative values, but when you are passing them to DiagramObjects.AddNew you specify them as positive values.  You will need to change the values you are passing though - at the moment you have the left, right, top and bottom all on the same x/y position.

The actual problem in the code sample you provided is that you are only creating a DiagramObject.  You haven't created the actual Element for the boundary.

Try something like this instead:

Code: [Select]
EA.Package ParentPackage = repository.GetPackageByID( MyDiagram.PackageID );
EA.Element NewElement = (EA.Element)ParentPackage.Elements.AddNew("", "Boundary");

leftPos = 100;
rightPos = 300;
topPos = 100;
bottomPos= 200;

EA.DiagramObject NewDiagramObject = (EA.DiagramObject)MyDiagram.DiagramObjects.AddNew("l=" + leftPos + ";r=" + rightPos + ";t=" + topPos + ";b=" + bottomPos + ";", "");
NewDiagramObject.ElementID = NewElement.ElementID;
