wix - Service does not start after updating; how to do dependencies between components -


we have installer install windows service , files. when update installation new installation (by installing new package; minor upgrade, product version changes, product id not change), service cannot start. because files missing in installation folder needed service during service start up.

currently have <feature /> , there 1 <componentgroup />. <componentgroup /> contains service , contains other components, has files. looks (empty attributes placeholders , filled):

<component id="" guid="" directory="">     <file source="" id="" />     <file source="" id="" /> </component> <component id="" guid="" directory="">     <file source="" id="" />     <file source="" id="" /> </component> <component id="" guid="" directory="">     <file source="" id="" />     <file source="" id="" /> </component> <component id="" guid="" directory="">     <file source="" id="" />     <file source="" id="" />     <file source="" id="" />     <file source="" id="" />     <serviceinstall id="serviceinstaller" type="ownprocess" vital="yes" name="" displayname="" description="" start="auto" account="localsystem" errorcontrol="ignore" interactive="no">         <util:serviceconfig firstfailureactiontype="restart" secondfailureactiontype="restart" thirdfailureactiontype="restart" resetperiodindays="5" />     </serviceinstall>     <servicecontrol id="startservice" start="install" stop="both" remove="uninstall" name="" wait="yes" /> </component>

the bad thing service depends on other components.

how can specify dependencies? or need put files in component contains <serviceinstall />?

thanks, johannes

i suspect problem caused else. plan discover real problem run msiexec myapp.msi /log install.log , inspect resulting log file. log can prove whether files installed first , uncover issue.

during installexecutesequence when actual installation performed, windows installer installs components through sequence of actions. action lays down files on disk called installfiles, , action starts services called startservices.

unless tell otherwise, wix schedules startservices action after installfiles action, files should present on disk before service started.

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)...
