Adding SAP GUI scripting dll to custom activity

[Ilia_Elagin]

Greetings!

I’m trying to write a custom activity using Visual Studio C# and need to use sapfewse.dll there. While the package builds without any problems, UiPath returns an error, when I try to add a variable to any of the Activities. The library does contain “GuiSession” however. What could be the issue causing this error?

Thank you

@Ilia_Elagin,

Check if you could import the sapfewse dll in your workflow using Imports panel in Studio.

Thanks,
Ashok

@ashokkarale ,

Thank you for your answer!
The package appears to be imported and it shows up in the Imports panel.

@Ilia_Elagin,

Ok. What’s the variable datatype you have declared?

Thanks,
Ashok

@ashokkarale ,
I am also part of Ilias team and try to answer
in the c# code we have something like this:

sapfewse.GuiSession GuiSession = …

our reference to the libraries in the *.csproj looks like this:

..\libs\sapfewse.dll True ..\libs\saprotwr.net.dll True

@Sergey_Rysev,

Ok, so how you are creating instance of sapfewse.GuiSession and passing it?

@ashokkarale
we are trying to port the old UiPrime library to the the version of UiPath.
we took the code from here: GitHub - uiprimeteam/UiPrimePackage
and we assume the error happens either here: UiPrimePackage/UiPrime.SAP/Activities/_Common.cs at 91def66dfd3b10325a973f9610a2d14211844691 · uiprimeteam/UiPrimePackage · GitHub
or here: UiPrimePackage/UiPrime.SAP/Activities/_GuiSession.cs at 91def66dfd3b10325a973f9610a2d14211844691 · uiprimeteam/UiPrimePackage · GitHub

UIPath Invoke VBScript

Hello @Johann, in my opinion it is not necessary to transfer the GUISession object to the VBScript directly. You know the session object in your calling program. With the property ID you can get the full ID of the session as string, e.g. like this: /app/con[0]/ses[1] Dismantle this string to get the connection number, in this example 0, and the session number, in this example 1. Now you can transfer this numbers to your VBScript and use it like I described here. A tiny hint: It is not possib…

How to access SAP GUI objects' methods and properties

Hello, I’m trying to get access to various properties and methods of SAP elements (like this) using UiPath Studio. I can spy SAP elements via studio but they are UiElement type. And I can only access UiElement class methods and properties. I’ve tried using the invoke code, but cannot make it work. Although similar code works fine in VBA or VBS, I cannot make it work in the UiPath. The VB.net code is following, this is just a simple connector to an existing SAP instance: Dim SapGuiAuto As Ob…

can you check the presence of the sapfewse.ocx at the machine?

possible paths:
C:\Program Files\SAP\FrontEnd\SAPgui\sapfewse.ocx
C:\Program Files (x86)\SAP\FrontEnd\SAPgui\sapfewse.ocx
…

Hello @ppr ,
Thank you for your answer!
Yes, we have this file on the machine, where we use our custom activity.

Hello @LevKushnir
Thank you for your answer!
I went through both threads, but unfortunately couldn’t find the information that might help with our case. I have the assumption, that the issue might be with the library we are using, sapfewse.dll, being written with an older dotnet version, which is only supported in UiPath legacy projects.

We finally could reach the solution. It was important to set properties “Copy Local” and “Embed Interop Types” of each relevant import to yes and no respectively. It was also necessary to add the following lines for each relevant import inside the <Target Name="AddDlls"/> in *.Packaging Project:
