efka Posts: 799 Rating: (43)	violinette ... Do you have any idea to block my navigation button while my view isnot entirely loaded ? You can write a script which includes incrementing timer. If timer is 0 then your navigationbar is enabled. BUT, this is not a real solution, because if timer is so "short" your buttons will be enabled, before picture is loaded. I don't have any other idea to solve such a task. best regards

I suppose that your navigation button is in the buttons bar image and the image that you want to go represented in the working area. #include "apdefap.h" void OnClick(char* lpszPictureName, char* lpszObjectName, char* lpszPropertyName) { char pictname[256] = ""; char mon = '1'; // this code is only to know if it is loaded the image that you want to go mon = SSMGetScreen( lpszPictureName ); /* This function indicates the monitor in which the image (buttons bar image) is visualized SSMGetWorkFieldPicture( mon, pictname, sizeof(pictname) ); /* This function determines the name (including the extension) of the current image visualized in the workspace, I suppose that if this function returns the name of the image is because it is totally loaded in runtime with all the objects that contains / if ( ( strcmp(pictname,"The_Name_of_The_image_you_want_access .pdl") ) ) SetPropBOOL(lpszPictureName,lpszObjectName,"Operation",0); / if the image to which you want to consent is not loaded in the workspace I disable the navigation button, to give an example */ best regards }

First I should check when this name getsactive after the load instruction.... at the same time as loading, or after loading. I think you canalso use or try VBS: HMIRuntime.ActiveScreen.ObjectName If this doesn't work, then you can try this: I guess that the objectwhich is addedaslast, is alsothe latestloaded. So maybe you can also check this object name. HMIRuntime.ActiveScreen.ScreenItems("name of the object").ObjectName (or the C variant of this instruction)

violinette Posts: 12 Rating: (0)	Hi jm1983, I tried your solution, but the function "SSMGetScreen()" is unknown by the compiler. I workactually with WinCC V6.2 SP4. I didn't install the software PCS7. So I think I don't have the Basic Process Control. Do you have a solution without installing PCS7 ? Best Regards,

Advanced Process Control is part of PCS7 installation (and also only available for PCS7). just for your information regards
