I developed a .NET 4.6 Framework project (X64) with access to the running sap-instance. to connect to sap i used the exactly same way as the SAP-Script:
Script-Version:
Set SapGuiAuto = GetObject("SAPGUI")
Set application = SapGuiAuto.GetScriptingEngine
...
.Net Framework 4.6.2 / .Net6 Version:
Dim SapGuiAuto = GetObject("SAPGUI")
Dim application = SapGuiAuto.GetScriptingEngine`
Dim SAPCONN = application.connections(0)
Dim SAPSESS = SAPCONN.children(0)
SAPSESS.findById("wnd[0]").ElementVisualizationMode = False
In .NET Framework 4.6, I got access to an SAP system and the connection was working.
Now I updated to .NET 6 and the first code line (SapGuiAuto
) reports this error:
Fehler beim Laden der Typbibliothek/DLL. (0x80029C4A (TYPE_E_CANTLOADLIBRARY))
Second line then crashes because object has no type GetScriptingEngine
.
It looks like some files are missing but if this would be the case it should not work in .NET 4.6 project.
On the same computer, same installations if I try the same again in .NET 4.6.2, it is still working ... What am I doing wrong? Can it be that GetObject
behaves not the same in different framework versions? What can I do to fix this issue?
Thank you in advance for your help!
NB: I already tried to add/and remove the COM libraries (SAPFEwse
) from the project but this seems to make absolutely no difference if this is included or not...
I tried also to install the outdated nuget library "SAP.GUI.Scripting.Net".
which in fact is just ROT WRAPPER and the SAPFEWSE
Library. Also no success with this Library.
