Get progress when building an EXE with Application Builder API

[RogerSaele]

Found out about the U64 input to "Load_From_Project.vi".

As per https://forums.ni.com/t5/LabVIEW-Project-Providers/FAQ-about-LabVIEW-Project-Providers/m-p/3494834?p...

you can use the following to get it: <LabVIEW>\resource\Framework\Providers\Common\provcom_GetObjectItemFromProjectItem.vi

for which you can supply build spec ref. Lo and behold, I was able to programmatically build with progress (see attached example)!

Merry Christmas! 🙂

The example was LabVIEW 2020 though. Attached are 2015 and 2018 versions.

Merry Christmas indeed! Hopefully the OP sees this and marks it a solution. But just in case:

^^^Solution for building installers with progress by @RogerSaele

Thanks for posting.

Just discovered that one can also use "AB_API Get Build Object.vi" (which is used by "Open_EXE.vi", first VI in Voky's solution, from "NI_AB_API_EXE.class"), selecting installer as build object type, and providing project refnum and build spec name:

The build object output can be used as input to "Load_From_Project.vi".

Yet another solution. Opens up a native LabVIEW build window.

Hi Matthias,

Sorry this is a little late.  "Create progressbar event.vi" creates user events for the Application Builder API to pass messages with, I would guess the normal pop-up window utilizes these events.  Below is a quick and dirty snippet example of using these events to show build status.

I tried to build a RT application using this approach, it worked fine, but when I added the WebService to the buildspec I got a "Recursive Call at Build_Restful.vi" (I need to get the exact error and update the post), and then the build stopped.

Anyone else had this issue before? (LV 2017SP1)

SOLVED!
There is a bug in the Build.vi when trying to build an application with web services.

The fix consist in changing the reentrancy of the Build.vi from Non-reentrant to Shared Reentrant and of course all the implementations of the Build.vi in different classes (it is a dynamic dispatch VI)

This is possible with newest version of the LabVIEW where this API is not password locked.
