posted December 16, 2010 4:57 PM Hi, I have created a DLL for the screen scraping code (which mostly contains telnet1.read and telnet1.write commands to send instructions to telnet server). This is working fine if I use it without any UI, i.e. from a console application. But I have another project which has Windows form (similar to the one TelnetClient project in Winforms directory in the samples), when I try calling the screen scraping function from this form (which also has the VT object) I experience the following two issues: 1. it locks my form and doesnt allow me to do anything with it (like opening debug form or opening menus) 2. I do not get the UI back until the complete process is over. Once its done I get the final state of the UI back to my VT control. I guess I am not able to Marshal each step back to the VT control on my form but how do I do that? Could you please provide some guidence on how to proceed on this? Thanks & Regards, Chitrang Golvelker |

posted December 17, 2010 9:36 AM Hello, The UI is unresponsive because blocking code is being run on the UI thread; an explanation of how to implement asynchronous operation is included in the help documentation under the topic 'Asynchronous Operation'. If you have any questions, please let me know. |
