Can't add a reference that has been removed

[egan857]

Hi, I was experimenting with C# and got in out of my depth. I was trying to find a way to connect to Oracle, and ran into problems with the DLLs. I have been copying DLLs into the NT bin directory (c:\Program Files(x86)\NinjaTrader 7\bin), and then adding corresponding references to those DLLs by right-clicking in the strategy editor and selecting "References". So far, so good: I was able to add DLLs and references to them.

Then I had some compile errors that appeared to be problems with the System.dll. I downloaded a new System.dll from Microsoft, copied it to the NT directory, and then added a reference to it. That didn't work, so I removed the reference to "System.dll" so the new reference would take precedence. Now my programs won't compile and I can't back out the change since I can't add a reference to just "System.DLL" - the References screen forces me to put in a file path. I would assume the reference list is somewhere - can I just edit it to add the "System.dll" reference?

Hello egan857,
Thanks for your post and I am happy to assist you.

The System.dll file resides in the .Net Framwok folder and you have to give reference to it. Typically you can locate in the following path. C:\Windows\Microsoft.NET\Framework64\v2.0.50727\Sy stem.dll depending whether you are running a 32 bit or 64 bit OS and what version you are using.

Please add a reference to it and let me know if everything is working fine or not.

Hi Joydeep,

Thanks! Actually, I found a similar error by upshon and his solution was to edit config.xml to restore the entry to system.dll. But, your reference to the Microsoft.Net Framework directory solved the problem that caused me to get into this mess in the first place. When I added the Oracle.DataAccess.Client dll and the commands to connect to Oracle, I got a compile error about missing commands from System.Data. I misunderstood that and replaced the System.dll reference to a new version of System.dll. Now I have removed that System.dll and added just "System.dll" to the reference list so it uses the Microsoft.Net Framework version. I also copied System.Data.dll from the Framework directory to the NinjaTrader directory, added a reference to it, and now my Oracle connection compiles, too. I don't know if I can connect to Oracle, but it looks promising. Thank you, thank you, thank you!

Hello egan857,
Glad to know everything works fine.

NinjaScript is all C#. If the Oracle connection works in Visual Studio then it should work in NinjaScript too.

Please let me know if I can assist you any further.
