Can't load dll file in coreconsole

Miralkong — Mon, 15 May 2023 02:49:58 GMT

I've trying to use accoreconsole.exe to process a batch of files. According to Kean's blog(https://www.keanw.com/2012/02/the-autocad-2013-core-console.html), coreconsole can also load CRX modules and .NET DLLs that have been coded against the new AcCoreMgd.dll (rather than AcMgd.dll). In my code I only used AcDbMgd.dll and AcCoreMgd.dll as references. However, When I tried to load my dll in coreconsole, it showed that "can't load *** assembly".

My accoreconsole.exe version is 2021. And my code structure is as below:

[CommandMethod("TEST", CommandFlags.Session)] public void TestCode() { Document acDoc = AcadCore.Application.DocumentManager.CurrentDocument; Database acDb = acDoc.Database; using (DocumentLock acLock = acDoc.LockDocument()) { using (Transaction acTrans = acDb.TransactionManager.StartTransaction()) { // Logic code acTrans.Commit(); } } acDb.SaveAs(acDoc.Name, true, DwgVersion.Current, acDb.SecurityParameters); }

Could someone tell me why this is happening? Thanks a lot.

Hi,

You should show how you load the DLL.

Another thing, is the CommandFlags.Session mandatory for the TestCode method?

Hi,

I've tried 2 ways to load the dll file. The first one is to open accoreconsole.exe directly and in the command window enter netload. Then when it asks the dll file path, I enter the full path of the released version. The second way is to start a accoreconsole process and then try to load the dll file using StreamWriter.WriteLine() Method. The main structure is as below:

private bool CoreConsleProcess(string programPath, string dwgFilePath, string scriptPath) { using (Process myProcess = new Process()) { myProcess.StartInfo.UseShellExecute = false; //myProcess.StartInfo.CreateNoWindow = true; myProcess.StartInfo.FileName = programPath; myProcess.StartInfo.RedirectStandardInput = true; myProcess.Start(); StreamWriter myStreamWriter = myProcess.StandardInput; myStreamWriter.WriteLine($"open {dwgFilePath}"); //myStreamWriter.WriteLine($"script {scriptPath}"); myStreamWriter.WriteLine(@"netload dll full path"); myStreamWriter.WriteLine("test"); //myProcess.WaitForExit(); myProcess.Close(); } return true; }

As to the session flag, because I have to save the current database at the end of my code, in my test, if session flag is not assigned, some error is thrown. And I just removed the command session. It can't be loaded neither.

Hi Gilles,

This morning I did more test And I found that If I put the dll file in the directory of which the accoreconsole.exe is in, it can be loaded successfully. I don't know if there is a path length limitation in accoreconsole which causes the problem. But it worked in my case. Thanks again.
