Reading WinCC OA Version and Patch number

[RudiKreiner]

I stumbled over the predefined symbolical constants VERSION and VERSION_DISP in the Online Help Function recently and decided to use them right away to display this information in our UI for diagnostics purposes.
It would be nice to have a constant for the patch level too.
Is there any way of accessing that?

I total agree but you can make your own const

Code: Select all

string getPatch()
{
  
  dyn_string dsReadmes = getFileNames(WINCCOA_PATH,"ReadmeP*.txt");
  string sReadmeFile = "ReadmeP";
  string sText = ".txt";
  string sZero = "0";
  
  if ( dynlen(dsReadmes) )  
  {
    this.visible = true;
    dynSort(dsReadmes, true);
    
    for ( int i = 1; i

Hello,

it's possible to check the version incl. patch-level via the mentioned code (about.pnl).
There is no constant for the patch-level existing.
The control constant "VERSION_DISP" shows not only the version but also the "service pack number" (eg. WinCC_OA 3.11).
Nowadays, we don't count on "service packs". So version "3.15" is correct because we implemented no "service pack" so far.

best regards,
Andreas

Since 3.15 there is the new CTRL function getVersionInfo() with which you can get all sorts of version information

good to know

please refer to WinCC_OA Help (3.15):
[CONTROL - Control functions - getVersionInfo()]
-->
Description:
The function returns the current version information of WinCC OA.
The return values depend on the used key value and can be used to e.g. distinguish between patch, version (major or minor) or used platform.
