  Hello, colleagues.

  I have strange behavior of PDLCSSetPropertyEx ODK function.
 
  This code work properly:
  strcpy(ObjName, "Mixer");
  Value = 114;
  if (PDLCSSetPropertyEx(ProjectName, PictureName, ObjName, "Width", VT_I4, &Value, 0, NULL,   &Error )==FALSE){
    printf("\r\nError in PDLCSSetPropertyEx\r\n%s\r\n", Error.szErrorText);
  }
  After I execute this script in runtime and restart Runtime my object "Mixer" has width = 114, and this width is set in the object properties in Graphic Designer.

  This code work strange:
  strcpy(ObjName, "Mixer");
  Value = 1;
  if (PDLCSSetPropertyEx(ProjectName, PictureName, ObjName, "Visible", VT_BOOL, &Value, 0, NULL,   &Error )==FALSE){
    printf("\r\nError in PDLCSSetPropertyEx\r\n%s\r\n", Error.szErrorText);
  }
  After I execute this script in runtime and restart Runtime my object "Mixer" is visible (befor executing script I have set property "Visible" to "No" and it is realy was not visible). But if I open Graphic Designer the property "Visible" is set there to "No". However object is visible!

  That is this?!
  I try to solve this problem whole day! But not success.
  Experts, please help!

Hello,


From "Picture Creator for WinCC (Open Source)" :
http://support.automation.siemens.com/WW/view/en/45947736


In file "ObjectGeneration.cpp" at line 154:
We need a "int" variable
http://msdn.microsoft.com/en-us/library/cc235117(v=prot.10).aspx


else if(vt == 11) // BOOL
 {
  iValue = atoi(szValue);
  ret = PDLCSSetPropertyEx(pConnect->szProjectFile, szPictureName, szObjectName,
     szPropertyName, vt, &iValue, 0, NULL, &Error);

  Hello, perdahlqvist!
  Unfortunately, I don't understand what is the differ between my and your code. I try to set Value =0xFFFF. But no success.
  And what is the instruction "atoi". ODK has not this instruction.

 Best regards, SpKV.

 Do you mean that PDLCSSetPropertyEx work only with type VT_I4?

 Best regards,SpKV.

Hi SpKV,
As I see in the help of the WinCC-ODK, the argument "vt" of this function
( BOOL PDLCSSetPropertyEx (LPCTSTR lpszProjectName, LPCTSTR lpszPictureName, LPCTSTR lpszObjectName, LPCTSTR lpszPropName, VARTYPE vt,LPVOID pvProp, DWORD  dwFlags, LPVOID pData, PCMN_ERROR pError );

should not contain variants types and VT_BOOL is a variant type:

" vt

Data type of the value passed with pvProp. Valid types are defined in the "wtypes.h" Include file   belonging to the compiler.
No VT_VARIANT, VT_DISPATCH or other references should be used."

Proof using your variable "Value" as short (and vt = VT_I2) or as long (and vt =VT_I4) and assign it the values 1 and 0.

best regards

  Jm1983, excellent!

  This code work properly:
  strcpy(ObjName, "Mixer");
  Value = 1;
  if (PDLCSSetPropertyEx(ProjectName, PictureName, ObjName, "Visible", VT_I4, &Value, 0, NULL,   &Error )==FALSE){
    printf("\r\nError in PDLCSSetPropertyEx\r\n%s\r\n", Error.szErrorText);
  }
  After executing this code property "Visible" is set to "Yes" in Graphic Designer.

 Thank you very much!
