pcsoft.us.windevCopyright 2026, PC SOFT4 Mar 2015 16:42:12 Z3 Mar 2015 21:48:15 ZIs there anything special I have to do to reference controls on an internal window page from a different thread? The scenario is I have a window with an internal window control. The main window spawns a background thread that periodically checks for certain conditions. In the event that these conditions are met, I need to modify the properties of controls on the displayed internal window. Grey out buttons, ect. I know I can't reference the windows via IW_Name.ControlName..Property. That doesn't work. Is there something I'm missing? Thanks.30WEBDEVen_UShttps://forum.pcsoft.fr/es-ES/pcsoft.us.windev/50748-wd18-referencing-controls-internal-window-from-different-thread/read.awpmoderateur@pcsoft.fr (El moderador)webmaster@pcsoft.fr (El webmaster)robpcsoft.us.windevhttps://forum.pcsoft.fr/es-ES/pcsoft.us.windev/50748-wd18-referencing-controls-internal-window-from-different-thread-50766/read.awp4 Mar 2015 16:42:12 ZThanks again for the advice Fabrice.
