nsVersionInfo plugin setup from my Powerbuilder components page

Presentation

nsVersionInfo is a plugin that can manipulate the VersionInfo resource inside the Windows PE executables (.exe and .dll files), that is, the informations that are displayed when you right-click in explore and look at the "Version" tab. It can get and set information and has the special feature to be able to modify Powerbuilder executables without corrupting them (PB exes contain PB bytecode in an overlay at the end of the exe that is destroyed when using regular Windows resource API to modify the VersionInfo).

You can typically use it to:

• get the version of a file to check during installation
• change the version (or any other value from the VersionInfo) of an application while distributing a patch that only contains upgrade scripts (and you need to upgrade the exe version number for consistency)

Usage

Theses are examples from the sample in the installed files :

  var $testexe
 
  strcpy $testexe "$WINDIR\notepad.exe"
  nsVersionInfo::getFixedProductVersion $testexe
  pop $0
  DetailPrint "nsVersionInfo::getFixedProductVersion = $0"
  nsVersionInfo::getFixedFileVersion $testexe
  pop $0
  DetailPrint "nsVersionInfo::getFixedFileVersion = $0"
 
  ;WARNING : do that test with caution !!!
  ;nsVersionInfo::setFixedFileVersion $testexe 10 20 30 40
  ;pop $0
  ;DetailPrint "nsVersionInfo::setFixedFileVersion = $0"
 
  ;WARNING : do that test with caution !!!
  ;nsVersionInfo::setFixedProductVersion $testexe 11 22 33 44
  ;pop $0
  ;DetailPrint "nsVersionInfo::setFixedProductVersion = $0"
 
  nsVersionInfo::getStringFileInfo $testexe "FileDescription"
  pop $0
  DetailPrint "nsVersionInfo::getStringFileInfo (FileDescription) = $0"
 
  nsVersionInfo::getStringFileInfo $testexe "ProductName"
  pop $0
  DetailPrint "nsVersionInfo::getStringFileInfo (ProductName) = $0"
 
  nsVersionInfo::getStringFileInfo $testexe "LegalCopyright"
  pop $0
  DetailPrint "nsVersionInfo::getStringFileInfo (LegalCopyright) = $0"
 
  nsVersionInfo::getStringFileInfo $testexe "NonStandardString"
  pop $0
  DetailPrint "nsVersionInfo::getStringFileInfo (NonStandardString) = $0"
 
  nsVersionInfo::getLibVersion
  pop $0
  DetailPrint "nsVersionInfo::getLibVersion = $0"
 
  ;WARNING : do that test with caution !!!
  ;nsVersionInfo::setStringFileInfo $testexe "NonStandardStringUnTrucPasVu" "Une valeur a la con"
  ;pop $0
  ;DetailPrint "nsVersionInfo::setStringFileInfo (NonStandardStringUnTrucPasVu) = $0"
  ;nsVersionInfo::setStringFileInfo $testexe "FileVersion" "42.12"
  ;pop $0
  ;DetailPrint "nsVersionInfo::setStringFileInfo (NonStandardStringUnTrucPasVu) = $0"

Download

nsVersionInfo plugin setup

Exe setup contains the plug-in DLLs as well as documentation, source code and sample script.

libVerInfo the lib I used to make the plugin, it is not needed to rebuild it to build the plugin (a binary .a is already provided in the plugin sources).

Thanks

Fabien POTENCIER (aka User:fabpot) for his Perl_plugin that I reused as a basis for nsVersionInfo.
