To my problem: I have a problem with faceplates and can't find any solutions just by searching the forum. The problem is that the C-script I have written makes WinCC really unstable! I get a script error allmost evert time I try to run RunTime. If the error does not occur during loading it comes (sometimes) when I try to execute the script (by pushing a button, changing an I/O-field etc.). What I am trying to say is that sometimes the script error occurs and sometimes it does not. Everything seems to be working fine (the color change) as long as the script error does not appear. After it has occured everything stops and I can no longer change the tag (by writing in the I/O field). The script it set to change the color of a faceplate to indicate different statuses in a tag (DWord). The faceplate contains a circle, a rectangle and a picture. The script is placed outside the faceplate in the custom properties (UserDefined2) picture and the trigger is the tag I'm displaying (upon change). Is there any way to go around this error or any way to fix it? Thanks in advance! Attachment Diagnose.zip (368 Downloads)

In your UserDefined-Script line 19 you use strcat, please use strncat. other things i could not find. You should create outputs (printf) to contain the error(s). regards cumulus

bugmenot Posts: 31 Rating: (6)	Hi, cumulus! Thanks for looking into my problem I tried the "strncat" command [code]TAG = strncat(ToolTipPrefix,".CMD_STATUS",20);[/code] but it gives me the same error [code]@4 (21) : general protection fault..[/code] You mention memory overflow... what does that mean or rather how do I avoid it? And how do I use the "printf" command? This is probably basic programming knowledge, but as I don't have any programming background I have to ask :-/

bugmenot Posts: 31 Rating: (6)	Hi again. I've tried to comment out most of my script and tried to fix the memory leaks. It seems as there is an bug in Script.exe or something that prevents me from doing anything. What I want to know is whether or not my scripting is good? Memory leaks etc? And if anyone of you can try to run the little script and see if you get the same error? This is what is left of my script: [code] char* Grafikk = malloc(10); unsigned long Farge = 0x0; char* ToolTipPrefix = malloc(20); char* TAG = malloc(30); //int ModusFarge = 0x0; //int TilstandsFarge = 0x0; //int AnimasjonsModus; //int AnimasjonsTilstand; ToolTipPrefix = GetPropChar(lpszPictureName,lpszObjectName,"TagPrefix"); TAG = strncat(ToolTipPrefix,".CMD_STATUS",20); //Kombinerer Prefix med Suffix Farge = GetTagDWord(TAG); //ModusFarge = AnimasjonModus(Farge); //TilstandsFarge = AnimasjonTilstand(Farge); printf(ToolTipPrefix, TAG, Farge); Grafikk = "Motor.png"; printf(Grafikk); return Grafikk; free(Grafikk); free(ToolTipPrefix); free(TAG); [/code] When I copy this code into "Picture" in my Faceplateinstance and compile everything seems to be OK. Printf displays everything as expected, but when I try to stop runtime (or run runtime the next time) MSWindows displays an box: [code] --------------------------- C:\WINDOWS\system32\ntdll.dll --------------------------- Unhandled exception was raised. Look file "script.log" for details. --------------------------- OK --------------------------- [/code] And if I look at script.log I find this: [code] //==================================================================== // WinCC reported exception with code: C0000005 ACCESS_VIOLATION // Date: 15.12.2008 - Time: 12.32.38 // Caused at logical address 7C91888F 01:0001788F //==================================================================== // FAULTING MODULE: C:\WINDOWS\system32\ntdll.dll //==================================================================== // Registers: // ---------- // EAX:01E94000 // EBX:01DB0000 // ECX:01EB0000 // EDX:0000444D // ESI:004E0598 // EDI:01EAAAC8 // CS:EIP:001B:7C91888F // SS:ESP:0023:0012CCE8 EBP:0012CCFC // DS:0023 ES:0023 FS:003B GS:0000 // Flags:00010283 // // Call stack: // ----------- // Address \| Frame \| // ---------+----------+---------------------------------------------- // 7C91888F \| 0012CCFC \| RtlReAllocateHeap+E92 // 7C918238 \| 0012CD34 \| RtlReAllocateHeap+83B // 7C911C76 \| 0012CF64 \| RtlInitializeCriticalSection+149 // 78134D83 \| 7C9105D4 \| malloc+7A // 06F06800 \| 00020468 \| 0000:00000000 C:\Program Files\Siemens\Siemens\WinCC\bin\SCRIPT.EXE //==================================================================== [/code] Thanks!

bugmenot Posts: 31 Rating: (6)	Hi! I think I've finally figured out most of the bugs in my code. Now everything works fine at runtime (no crashes etc.), but I still get errors when stopping runtime. Sometimes it goes good and WinCC Runtime closes normally, but sometimes I get these errors: [code] --------------------------- C:\WINDOWS\WinSxS\x86_Microsoft.VC80.MFC_1fc8b3b9a1e18e3b_8.0.50727.762_x-ww_3bf8fa05\MFC80.DLL --------------------------- Unhandled exception was raised.

This comand should look like that: printf ("ToolTipPrefix: %s TAG: %sFarge: %s \r\n",ToolTipPrefix,TAG,Farge); %s= the place were the variables are insert. \r\n= first position in new line. a memory overflow you get wenn the memory-space of the tag not big enouth. Thats possibel when you copy, add ect. strings. Also the printf-function can case memory overflows. imagination. for all variables, you define, it will be space reserved in the RAM. If you overwritethe tag with a bigger size, you overwrite thespace behind the reserved space. In my experience, mostly that damage the skript.exe . But notallways alone. regards cumulus

bugmenot Posts: 31 Rating: (6)	Thanks for all replies! I have figured out a solution for the problem! This was the faulting code: [code] Prefix = GetPropChar(lpszPictureName,lpszObjectName,"TagPrefix"); strncat(Prefix,".CMD_STATUS",40); //Kombinerer Prefix med Suffix [/code] This is how it should have been (working): [code] strcpy (Prefix, GetTagPrefix(lpszPictureName,lpszObjectName)); strcpy (Tag, ".CMD_STATUS"); strncat(Prefix, Tag, 40); [/code]
