You are exactly right. I thought that by clicking "Update All", I was setting all fields to be updateable, even the primary key fields. I see now that you have to manually check the primary fields. THANKS!

I am trying to insert a record into an MS SQL table via a remote view. When I update the table, I get an error stating that a null value is not allowed in the column, even though the field is not null. Any help would be appreciated. Thanks

The control sends and receives messages using Open Modbus protocol for controlling industrial processes via Ethernet TCP/IP. The class encapsulates twelve methods for establishing connections, reading registers, presetting registers, etc. The object is instantiated once and then function calls...

I am still experiencing trouble passing an array to the COM object after invoking COMARRAY(). I have tried various settings for the nNewValue argument (i.e., 0, 1, 10, and 11), but I always get the same error, "Error building array". The code looks like this: o =...

I need to call an ActiveX object function from VFP 6.0. The function declaration is: HRESULT PresetMultipleRegisters([in] short Addr, [in] long DataStart, [in] short Quantity, [in] VARIANT vRegValues) In VB the syntax that works is: <object>.PresetMultipleRegisters(1,4,3,array) where array...

Thanks for the help. The class was identified in the registry as &quot;modbussrv.modbussrv.1&quot;.

The file was registered with windows. Because it is an executable, it was registered using the syntax: MBServer.exe /RegServer

I have tried and have gotten an error message, &quot;...file does not exist&quot;.

Two very good applications are robohelp and forehelp (developed by forefront). Of the the two, I would recommend robohelp.

That is the oddity. The class does not appear in the ActiveX controls list, although it is visible in VFP's object browser and in VB references.

Application is not included in the public interface. Only properties and functions specific to the class are visible.

The code in VB is: Public oModbusServer As ModbusSrv Set oModbusServer = New ModbusSrv In VFP, I have tried: (1) oModbusServer = CREATEOBJECT(&quot;ModbusSrv&quot;) (2) oModbusServer = CREATEOBJECT(&quot;ModbusServer.ModbusSrv&quot;) Both of these VFP statements result in the error...

I have an ActiveX server executable that is functional in VB, and its interface is viewable in the object browser of VFP 7.0, but I am unable to instantiate an object using CREATEOBJECT(). Is there a way to use its classes in Visual Foxpro?
