Custom DLL incorrect format error CS0009

[AusTrader]

Hi,


I am using NT 7.0.1000.37 and have written a custom DLL in Delphi XE7 (version 21.0.17017.3725). NT7 is 64 bit and the DLL generated is 64 bit.



When compiling my indicator I get the error:


Metadata file 'c:\Users\xxx\Documents\NinjaTrader 7\bin\Custom\DLLname.DLL' could not be opened -- 'An attempt was made to load a program with an incorrect format.' CS0009.


There is no specific help for CS0009. Other custom DLL errors on the forum are not for Delphi.


What needs to change about the format of my Delphi DLL to load and work with NT7?


Thanks

Which version of .NET did you target?

[AusTrader]

.NET 3.5. That is the correct version for NT7 isn't it?

I'm currently working on writing a Visual Studio .NET 3.5 wrapper for the Delphi DLL. No success yet. But will post when I make progress or need help. Which ever comes first :-)

Msvcp1

Your DLL may not be compatible with .NET or with .NET’s 32-bit mode. Ensure that your DLL is .NET compatible. After that check DLL file format is correct or incorrect. It is common errors occur mostly. You need to download msvcp140 file .I am pretty sure after install dll files your error message must disappear .
