Fpga: dynamic mode vs type def for FPGA ref

What are the differences for dynamic mode and type def for FPGA referenece? When should I use which? Is there a scenerio when I should use neither?
Kudos and Accepted as Solution are welcome!

So, you can still create a Type Def of a Dynamic Interface Refnum... That sounds confusing I know. Basically, my design flow is generally as follows:
Develop initial FPGA code.
Create a Control or Type Def with the FPGA Interface control configured for my FPGA VI.
Develop my host, and use the Type Def in all of my subVIs.
If I need to edit my FPGA code, now I only have to update the control in the typedef to propagate my interface changes to all of my subVIs
Basically, every project I do has a FPGA Reference typedef for use in my host VI.
Attached, you can find a (incomplete) sample project of mine that does this.

No Data Change event generated for a XControl in a Type Def.

Hello,
Maybe I am missing something but the Data Change event of a XControl is not called when the XControl is used in a Type Def. or Strictly Type Def. (see the attached file).
There may be some logics behind it but it eludes me. Any idea of why or any idea of a workaround still keeping the Type Def. ?
Best Regards.

XControl No Data Change event.zip ‏45 KB

Hi TWGomez,
Thank you for addressing this issue. It must be a XControl because it carries many implemented functions/methods (though there is none in the provided example).
Also consider that the provided non-working example is in fact a reduction of my actual problem (in a 1000-VI large application) to the smallest relevant elements. In fact I use a typedef of a mix of a lot of different XControls and normal controls, some of them being typedef, strictly typedef or normal controls and other XControls of XControls (of XControls...) in a object oriented like approach...
Hi Prashant,
I use a typedef to propagate its modifications automatically everywhere it is used in the application (a lot of places). As you imply a XControl would do the same, though one would like to construct a simple typedef when no additional functionality is wanted.
The remark "XControl=typedef+block diagram" is actually very neat (never thought of it that way) because it provides a workaround by transforming every typedef into a XControl. Thanks very much, I will explore this solution.
One issue remains: All normal controls update their displayed value when inserted into a typedef but not XControls. Data change event is not triggered. I known that XControls have some limitations (no array of XControls) but I would say, like TWGomez, that this is a “bug” considering the expected functionality.

What are type defs used for?

I am learning about type defs and wanted to ping the community to get a feel for what expanse of things they are useful for. Any and all comments are welcome.

Don't forget Kudos for Good Answers, and Mark a solution if your problem is solved.

I found this (from LV Help) enlightening as to the differences between typedefs and strict typedefs:
Type Definitions and Strict Type Definitions
Use type definitions and strict type definitions to link all the instances of a custom control or indicator to a saved custom control or indicator file. You can make changes to all instances of the custom control or indicator by editing only the saved custom control or indicator file, which is valuable if you use the same custom control or indicator in several VIs.
Type Definitions
Type definitions identify the correct data type for each instance of a custom control or indicator. When the data type of a type definition changes, all instances of the type definition automatically update. In other words, the data type of the instances of the type definition change in each VI where the type definition is used. However, because type definitions identify only the data type, only the values that are part of the data type update. For example, on numeric controls, the data range is not part of the data type. Therefore, type definitions for numeric controls do not define the data range for the instances of the type definitions. Also, because the item names in ring controls do not define the data type, changes to ring control item names in a type definition do not change the item names in instances of the type definition. However, if you change the item names in the type definition for an enumerated type control, the instances update because the item names are part of the data type. An instance of a type definition can have its own unique label, description, default value, size, color, or style of control or indicator, such as a knob instead of a slide.
If you change the data type in a type definition, LabVIEW converts the old default value in instances of the type definition to the new data type, if possible. LabVIEW cannot preserve the instance default value if the data type changes to an incompatible type, such as replacing a numeric control or indicator with a string control or indicator. When the data type of a type definition changes to a data type incompatible with the previous type definition, LabVIEW sets the default value of instances to the default value for the new data type. For example, if you change a type definition from a numeric to a string type, LabVIEW replaces any default values associated with the old numeric data type with empty strings.
Strict Type Definitions
A strict type definition forces everything about an instance to be identical to the strict type definition, except the label, description, and default value. As with type definitions, the data type of a strict type definition remains the same everywhere you use the strict type definition. Strict type definitions also define other values, such as range checking on numeric controls and the item names in ring controls. The only VI Server properties available for strict type definitions are those that affect the appearance of the control or indicator, such as Visible, Disabled, Key Focus, Blinking, Position, and Bounds.
You cannot prevent an instance of a strict type definition from automatically updating unless you remove the link between the instance and the strict type definition.

Mode linkage types for suboperations in PP/DS PDS

Dear SAP Experts,
Do you know any way to control the mode linkage type for suboperations in PP/DS PDS? I'm changing the PDS during the generation with BADI CUSLNTRTO_ADDIN in the ECC side but unfortunatelly I couldn't find the suboperation relationships in any of the Methods available. In the Method CHANGE_CIF_STRUCTURES I have the parameter CT_ACTREL in which I'm already changing all available mode linkages to type 3 (same mode number) but unfortunatelly I don't have any option in this table for the suboperation.
We are using suboperations to be able to schedule a PRT according to the available documentation.
I would appreciate any idea / suggestion.
Thanks and BR
Mauricio

Dear Saurabh,
I couldn't find a place to change the mode relationship type of operation-suboperation relationship. In the table CT_ACTIVITY I could find the suboperation and the mode relationship type is set to 3 (desired one) but when the PDS is transferred to the APO system this relationship type is set to 0.
This is happening just in the relationship between operation and suboperation.
Thanks and BR
Maurício

Problems with Type defs in dynamic VIs

I have created a Labview executable that consists of a top level VI that dymamically calls a Front Panel VI.
To build this I have added the Front Panel.vi as a support file, and then set the installer to create a Front Panel(s) directory to put the vi in.
When I run my .exe I get an error saying that the Front Panel.vi is not executable. I have eventually found out that if I disconnect a control I have in the front panel from its type def then everything works fine, so this looks like it's the problem.
It's not the end of the world not having the type def connected, but it is a bit inconvenient if I want to make changes to the front panel - just wondering if anyone knew how I could get this type def included in the build, and for the front panel as a support file to be able to see it.
Many thanks in advance for any responses.

Hi,
You have to uncheck "Disconnect from type defs" when you build an executable.

Change table size and headers in type def cluster

Is is possible to change a table size and headers that is inside a type def cluster?
I have a vi that loads test parameters from a csv file. The original program used an AC load so there was a column for power factor. I now have to convert this same program to be used with a DC load, so there is no power factor column.
I have modified to vi to adjust the "test table" dynamically based on the input file. But the "test table" in the cluster does not update it's size or column headers.
The "test table" in the cluster is used through out the main program to set the values for each test step and display the current step by highlighting the row.

Table Cluster.JPG ‏122 KB

Nevermind, I figured it out...
I was doing it wrong from the start, in an effort to save time writing the original program I simply copied the "test table" to by type def cluster. This worked but was not really as universal as I thought it would be, as the table was now engraved in stone since the cluster is a type def.
I should not have done that, but rather used an array in the cluster and only used the table in the top level VI where it's displayed on the screen.

How do I make a Type Def an Enumerated type?

Bare with me as this is my very first time using a Type Def
I tried following the tutorial at http://zone.ni.com/devzone/cda/tut/p/id/5318
The first one worked alright that was the Master Mode, but that was starting with a previously created control.
My first attempt at creating a new control did not go so well, see my Sys1 control.
How do I make the control an enumerated type so it names the cases for me when creating a new control?

No one mentioned in this thread yet so I add...
That if you do a right-click replace then naviagte to a enum, the new enum will retain all of values and you don't have to re-enter them.
An extention of this idea is useful when creating an enum with a 100 values or more. Write code to populate a ring control with the required strings then after, dod the replac with thing.
Sure has saved me a lot of work.

Making condition type unmandatory for free item categories

Hi all,
I've created a form routine in RV64ANNN the requirement is when we create or change sales order....we have few item categories were in we need to make a concern condition type unmandtory if items with those item category is created...else if make the condition type mandatory.........example...............this is done for only one pricing procedure......in V/08 tcode and there i've assinged our routine number for that condition type which needs to be changed dynamically.
say we have Sales doc type ZXXX for this sales doc type lets say we have item category ZITE1 and ZITE2.......and lets say the Condition type is ZCOND(whether the condition type is required or not is done by checking in tcode V/08 and this is always checked).now when the user enters creates a item 1 with item category ZITE1 and leaves the amount field blank it will however ask to enter the amount.......now here is the problem............if user creates second line item with item category ZITE2 its againing asking to enter the amount for that condition type.............this is happing even after i've desinged the below code.............

I've resolved it by myself

The type initializer for 'System.Data.SqlClient.SqlConnection' threw an exception. InnerException: Requested registry access is not allowed.

I have read some of the other posts for people that got this error, but none seem to apply to me.
My program has been working for weeks. I made some minor changes, and started getting the error (full details below).
I did a TFS "undo pending changes" and still getting the same error, even after logging off. The one odd thing is that I did change my Windows password this week. The connection string is using a SQL user id and password that has no issues.
I'm an Admin own my own box (running WIn XP SP3). I even tried "Run as Admin" on Visual Studio.
I'm doing a Debug-Start, running a Console-Test-Program that calls a WCF service, which on local machine is hosted by "ASP.NET Development Server".
We have two other developers, one has the same problem, one does not. In theory, we have all done "get latest" and are running the same code.
The SQL Connection is related to a trace database; we are using this library http://ukadcdiagnostics.codeplex.com which has worked fine for months.
When I do "Start Run" in Visual Studio, I get this error:
{"The type initializer for 'System.Data.SqlClient.SqlConnection' threw an exception. "}
with InnerException: {"The type initializer for 'System.Data.SqlClient.SqlConnectionFactory' threw an exception."}

I think I found it... this is sure a strange error for what is really happening.
Apparently it had happened to me before, and fortuantely, I actually added the following comment:
            // Above is related to the WCFLOG SQL Diagnostics Trace
            // If you get error here an inner exception "requested registry access is not allowed"
            // inside exception "type initializer for System.Data.SqlClient.SqlConnection"
            // then make sure you have impersonation enabled in your client.
            // See AdminConsole web.config or FRB.EC.AdminService.ConsoleTester.app.config for examples
Now I think I will do a try catch and spit out the same text.
Still testing to assure that this really was the issue.
      <endpointBehaviors>
        <behavior name="FRB.AllowImpersonate ">
          <clientCredentials>
            <windows allowedImpersonationLevel="Impersonation"/>
          </clientCredentials>
        </behavior>
      </endpointBehaviors>
The line below in BOLD below is what somehow seemed to disappear from my app.config - probably due to a TFS human error - still checking that also:
        <client>
              <endpoint address="http://localhost:4998/AdminService.svc"
                              behaviorConfiguration="FRB.AllowImpersonate"
                              binding="wsHttpBinding"
                          bindingConfiguration="WSHttpBinding_IAdminService"
                             contract="svcRef.IAdminService"
                        name="WSHttpBinding_IAdminService">
                    <identity>
                          <dns value="localhost" />
                    </identity>
              </endpoint>
        </client>
Here's how I "idiot-proofed" this error for now, to give an error that actually at least points to a solution:
        public SqlDataAccessCommand(string connectionString, string commandText, CommandType commandType)
            try
                _connection = new SqlConnection(connectionString);
                // Above is related to the WCFLOG SQL Diagnostics Trace
                // If you get error here an inner exception "requested registry access is not allowed"
                // inside exception "type initializer for System.Data.SqlClient.SqlConnection"
                // then make sure you have impersonation enabled in your client.
                // See AdminConsole web.config or FRB.EC.AdminService.ConsoleTester.app.config for examples
            catch (Exception ex)
                if (ex.ToString().Contains("The type initializer for"))
                throw new System.ApplicationException(@"
                Your client app <endpoint> must be cofigured have a
              'behaviorConfiguration' attribute like this:
                behaviorConfiguration='FRB.AllowImpersonate'
               that points back to a behavior that has this syntax:
          <behavior name='FRB.AllowImpersonate'>
             <clientCredentials>
                 <windows allowedImpersonationLevel='Impersonation'/>
             </clientCredentials>
          </behavior>
          ", ex);
               else
                    throw ex;
            _command = _connection.CreateCommand();
            _command.CommandText = commandText;
            _command.CommandType = commandType;
            // TODO _command.CommandTimeout = ;

Setting control to default value when it is a strict type def

If my subVI has a control that happens to be a strict type defined cluster and I have saved the values in the control as the default values, how can I change them back to the default values of the type def (which are empty). Because it is a strict type definition, i cannot click on the elements inside the cluster and modify them (e.g. click on an array inside the cluster and do an empty array operation.)
In the attached screenshot, the control "BLE Meters To Test" is just an array of clusters and I was able to empty the array. The control "Capture Data" is a strict type def. I would like to clear the contents of this control without having to delete the control and add it back with a new instance of the same strict type def.
Solved!

are you talking about edit mode or run mode?
You could temporarily add a second instance of the typedef (all empty), then change it to a constant. Whenver you need to reset at run time, write the new digram constant to a local variable of the control.

Make sure to click on the array container, not on the array elements.

How to identify update mode in function module for generic extractor

Hi All,
I have created generic extractor using function module which supports delta load.
Delta logic is handeled in coding...by using ROOSGENDLM table.
Now problem is we need to identify the update mode, requested from infopackage in our function module in order to apply logic for Repair full.
I would like to know table or parameter in source system, which contain the update mode (Init , Delta , Full).
Thanks,
Niraj

Hi Niraj
You can use the FM import parameter "i_updmode" (This is of type "SBIWA_S_INTERFACE-UPDMODE") to determine if infopackage triggerred in full or delta mode.
I_REQUNR     TYPE     SBIWA_S_INTERFACE-REQUNR
I_ISOURCE     TYPE     SBIWA_S_INTERFACE-ISOURCE                               InfoSource Name
I_MAXSIZE     TYPE     SBIWA_S_INTERFACE-MAXSIZE                               Data Packet size
I_INITFLAG     TYPE     SBIWA_S_INTERFACE-INITFLAG                               Initial Flag
I_UPDMODE     TYPE     SBIWA_S_INTERFACE-UPDMODE                               Update Mode
I_DATAPAKID     TYPE     SBIWA_S_INTERFACE-DATAPAKID                               Datapacket Id
I_PRIVATE_MODE
I_CALLMODE     TYPE     ROARCHD200-CALLMODE                               Single-Character Flag
I_REMOTE_CALL     TYPE     SBIWA_FLAG

Error Message--ITunes runs in 64-bit mode. Uncheck the Open in 32-bit mode in Get info for ITunes. However it is UNCHECKED. I cannot access itunes at all.What now?

Fallout75, good catch on the eXo plugin. To remove it, in the Finder click "Go" on the menu bar and pull down to "Go to Folder" and then type ~/Library/iTunes/iTunes Plug-ins
When that Finder window opens, you should see an "eXo" subdirectory. Just delete that "eXo" folder and iTunes should start without the error.

About Strict Type def

Hii
i have created a cluster of ring control as a strict type def.Also i have used a constant of that cluster in my program where i need.Now am changing the items in that ring control by opening the strict type def.I am giving Apply changes , save and all.Now the cluster in my program is changed.But my constant remains unchanged.;..How can i update a constant...

The wonders of searching (and that's just one of the results for my simple search).
Try to take over the world!
