My Application starts but I cannot type anything
Please initialize the license informatioin correctly - use method EditorStart
Where can I set the DLL in my VB (or similar) project which uses the OCX
You can set the DLL name even when the control is already displayed, the DLL can be exchanged dynamically. However we recomend to set the DLL name in the OnLoad event of the form.
Where should I store the PCC file?
The gui layout file (buttons.pcc) is searched relatively to the path of the engine DLL. So we recommend to install it into the same directory as the engine DLL - bes is the application directory, not the windows system directory!
When I drop the control on the form, why does it display just information text?
The OCX delays loading of the engine DLL to the last possible time. This has been made so to avoid that the DLL is loaded from an undefined or unwanted location. So the DLL is loaded not before the property DLLName has been assigned. This can happen during loading of the form at application start or by your own code. When the control is dropped on the form the property is not touched so the DLL not loaded.
When loading my form I get a "control not found" error message inside of MS Access.
Please open the VB Code editor and select 
"References" from menu "Extras". There you can disable the checkmark at the reference which was not found.
When I check out the contents of the blob field using a standard memo, I see only undefined characters
TextDynamic will usually save the text as single byte ASCII text - binary data may be included if images are used. A memo field expects double byte ole string. Such a string will be only saved if property TextFormat contains the parameter "-useolestring', otherwise the property Text will create a varaiant array of bytes.
