ecSDK C# Development

Tony Derrick

I am writing a c# winforms application where I want to be able to call the EC open dialog box and save dialog box and pass a particular path and filename to it and to then open/save a document.

I have a reference to ECSDK64.dll (C:\program files (x86)\OpenText\Enterprise Connect\ECSDK64.dll) and have imported the EnterpriseConnectSDK namespace.

Using the Dev Guide examples I have the following code:

OpenDialog Code:

private void OpenLiveLink()
        {
            object o = null;
            object Plugin = null;

            EnterpriseConnectSDK.IEnterpriseConnectSDK oSDK = null;

            oSDK = o as EnterpriseConnectSDK.IEnterpriseConnectSDK;

            EnterpriseConnectSDK.ICallContext context = oSDK.CreateContext();

            Plugin = oSDK.GetPlugin(context,"plugID");

            if (Plugin == null)
            {
                MessageBox.Show("Plugin object Creation failed. Exiting script");
                    return;
            }
            string ECItemID="";

            try
            {
                

            }
            catch
            {

            }

            finally
            {

            }
        }

 

SaveDialog Code

private void SaveLiveLink(string iFilePath, string iFileName)
        {
            object o = null;
            EnterpriseConnectSDK.IEnterpriseConnectSDK oSDK = null;
            EnterpriseConnectSDK.IPlugin plugin = null;
            EnterpriseConnectSDK.ICallContext context = null;

            oSDK = o as EnterpriseConnectSDK.IEnterpriseConnectSDK;

            context = oSDK.CreateContext();
            
            context.ParentWindow = 0;

            plugin = oSDK.GetPlugin(context, "pluginID");
            
            string FilePath = iFilePath;
            string initialFileName = iFileName;
            string[] ar = new string[]
            {
            "Word Document (*.docx)||.docx",
            "Word Macro-Enabled Document (*.docm)||.docm",
            "Word 97-2003 Document (*.doc)||.doc",
            "Word Template (*.dotx)||.dotx"
            };
            
            EnterpriseConnectSDK.ISaveContext SaveInfo = null;
            
            SaveInfo = oSDK.SaveDialog(context, ar, initialFileName);
            if (SaveInfo == null)
            {
            MessageBox.Show("Save Info object is null. Exiting script.", "");
            }
            else
            {
                                        
            }
        }

 

Both sets of code fail on the following line

EnterpriseConnectSDK.ICallContext context = oSDK.CreateContext();

with the error:

System.NullReferenceException was unhandled
  HResult=-2147467261
  Message=Object reference not set to an instance of an object.

I can't see what I have done wrong here. Any advise is welcomed.

Hello Tony,
first of all, your object "o" is null, than you are casting it to EnterpriseConnectSDK.IEnterpriseConnectSDK
So where does the "o" comes from ?

Have you seen this?
https://knowledge.opentext.com/knowledge/llisapi.dll?func=ll&objId=77371225&objAction=browse

I'm also trying to use EC SDK.

Lawrence Keller

Dear all,

We have EnterpriseConnect (EC) in our compagny and I am searching how to do excatly the same as Tony request. To open an EC dialog box (using VBA or Python). I have the ECSDK64.DLL installed but no documentation. And for now it is not foreseen to use the help of our IT department. So I don't know if we have a support contract.

In the example of Tony we have all information excepted how to get a link with the EnterpriseConnect server. The remark of Lukas is relevant; where does the "o" comes from ? I would say How to initialize the EnterpriseConnectSDK.IEnterpriseConnectSDK object oSDK in the program of Tony ?

If someone could help by showing us an example (in any computer language) to initiate a link with EC that would be really nice.

Thank you

Lawrence

Has anyone ever managed to get this to work?

I just want to display the SaveAs dialog from a VBA sub (in Excel). Surely that ought to be easy, but I can't work out the correct syntax, and there seems to be zero information out there.
