By default it is seen minimized in the task bar. We need to click on the window key and maximize the message box to make it appear on the WinCC screen. Later if any message box appears it comes to the screen withut any problem. This issue is seen only for the first popup of he message box after the start of WinCC. Please help me on this.

You can access this from Control Panel - Regional and Langauge Options - Languages tab - Details - Advanced tab. See attached screenshot. Regards Attachment R&L_Options.pdf (224 Downloads)

BAIJU Posts: 9 Rating: (0)	Thanks for your reply. I tried, but still it didn't work. By default "Extend support of advanced text services to all programs" was unchecked. Still for confirming I checked this field and retarted computer. Then again Iunchecked this field and again restarted the computer. I tried the message box popup after these procedures. Still the message box popup was staying in the taskbarduring first run after WinCC runtime start. While doing this I checked with using "PDLRTAllowSetForegroundWindow(NULL,NULL,NULL);" before calling the MsgBox(..); I also tried without using "PDLRTAllowSetForegroundWindow(NULL,NULL,NULL);" before calling the MsgBox(..); Still the same result. Is there any priority settings for the windows required?
