plenc Posts: 37 Rating: (0)	Hello, I want to make the button which gives possibility to minimize WinCC window. I don't want to exit WinCC or Stop runtime. Administrator should only has possibility to operate in windows but application havs to be in run mode. Any ideas? Best Regards, P.

F. Thomé Posts: 34 Rating: (11)	Hi plenc!!! i think that there is 2 ideas... This script maximize the window, you can use the same script to minimize the window, using parameter SW_MINIMIZE in the Showindow() function... Try it.. #include "apdefap.h" void OnClick(char* lpszPictureName, char* lpszObjectName, char* lpszPropertyName) { #pragma code("user32.dll") BOOL ShowWindow(HWND hwnd, int nCmdShow); HWND GetForegroundWindow(void); #pragma code() HWND Handle; Handle = GetForegroundWindow(); // get the Handle of the currently // topped window which usually is // WinCC Runtime if ( GetTagBit("Min_max")== 0) { ShowWindow(Handle, SW_MAXIMIZE); //maximize window SetTagBit("Min_max",1); } else { ShowWindow(Handle, SW_SHOWNORMAL); //set back to normal SetTagBit("Min_max",0); } } Or else, you can call a specific program to show, like winccexplorer, Windows Explorer etc.. like this... HWND aplication = NULL; aplication = FindWindow("WinCCExplorerFrameWndClass", NULL); if (aplication = NULL) { ProgramExecute("WinCCExplorer.exe"); aplication = FindWindow("WinCCExplorerFrameWndClass", NULL); } ShowWindow(aplication, SW_SHOWMAXIMIZED); PDLRTAllowSetForegroundWindow(NULL, NULL, NULL); SetForegroundWindow(aplication); To show Windows explorer, replace WinCCExplorerFrameWndClass with ExploreWClas. Good Luck!!!

stew Posts: 60 Rating: (12)	you got a typo in there F. Thomé if (aplication = NULL) Should read "==" instead of "=" Also for a different effect you can use [code]ShowWindow(Handle, SW_SHOWMINIMIZED);[/code] to minize the WINCC window totask bar.

stew Posts: 60 Rating: (12)	I'm not sure if you can do this with VB. (If somebody knows, please give me a hint how it can be done!) Why would you want to use VB? you can use both VB and C in a WinCC-project, so there's no problem of attaching the above code to a button while other actions use VB.
