migration - Migrate from Liferay Portal EE 6.1.20 to Liferay Portal CE 6.1.1 -


i migrate liferay portal ee 6.1.20 ga2 (developed locally trial version) liferay portal ce 6.1.1 ga2 (client requirement changed).

is possible use same db (with downgrade process possibly) , configurations, developed portlets, data etc.? lot of information stored in db (organizations hierarchy, users, roles, site , page templates, etc) , hard migrate manually exports-imports etc.

trying use same db throws following exception:

java.lang.illegalstateexception: attempting deploy older liferay portal version. current build version 6120 , attempting deploy version 6101.

is safe manually change liferay portal's build version in ee database's release_ table 6120 6101?

finally, implemented described in question , seems work fine.

i used same db liferay ee 6.1.20 installation , manually changed liferay portal's build version in ee database's release_ table 6120 6101. used liferay ce 6.1.1 bundle tomcat , copied ee bundle data folder (with document library files, etc) deployed plugins (themes, portlets, hooks etc) in webapps folder, configuration files (portal-ext.properties, etc.).

i throws in logs exception marketplace plugin version seems unobtrusive , invisible user , event marketplace feature works fine.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
