We have a Visual Basic 6 screen scraping application that was running in windows XP that I recently upgraded to VB.net running in Windows 7. I have Rumba 9.5 running on my workstation and I am using the WdMFDsp.Ocx from that version in my new code with the same parameters as in the old code. When I step through the .Net code, the pop form for the telnet does not appear and there is no connection to our mainframe. I am using Visual Studio 2017 Community version. Any suggestions on how I would resolve this?
Thank you.
#RumbaAre you receiving any error message /stack trace ?
Does it work when you manually configure a rumba mainframe session ?
I tested RUMBA 9.5 SP1 with VS 2017 Community Edition and it works as expected

Can you try and apply SP1 ?

#RumbaI am not receiving any error messages. This is the screen I am getting which is not our main frame screen:

Here is my Host Interface Configuration:

It may take me a while to get SP 1 so I hope we can figure it out using what I have.
Thanks for your help.

#RumbaYour screenshot shows a connection to the rumba demo host.
Try to set the the connection in your code.
MFDsp.HostInterface.Name = "WallData.TN3270Link" 'Sets Telnet Interface
MFDsp.HostInterface.Interface.InsertName2("yourhost.com") 'Insert Host Address
MFDsp.HostInterface.StartupModelType = 2 'Model 2
MFDsp.Connect()
