WiX Installer removes config file values on repair -

-

i have created installer copies config.ini , asks user values inserted ini file. works fine during fresh install , major/minor upgrades.

<component id="configini" guid="guid-goes-here" diskid="1">     <file id="configinifile"              name="config.ini"              source="../../artefacts/etc/template-config.ini"              keypath="yes"/>     <inifile id="valueone"              action="addline"              directory="etc"              section="sectionone"              name="config.ini"              key="valueone"              value="[valueoneproperty]" />     <inifile id="valuetwo"              action="addline"              directory="etc"              section="sectiontwo"              name="config.ini"              key="valuetwo"              value="[valuetwoproperty]" /> </component>

however, if user tries install same version of product installed, installer enters repair mode. i'm not sure how repair mode works, in case of config.ini file, seems deleting 1 populated values, copying again, , because it's repair it's not got user values populate config.ini file with, file blank.

is there way of getting installer ignore file on repair, or original user values?

the basic problem property values not being preserved. there no magic automatically saves values of properties between install , repair (or adding new features etc). problem not file being replaced because windows not replace files have been modified user data.

in wix, use "remember property" pattern save values of properties restored in these maintenance cases.

i using volley upload list of images server. happens within service. once image uploaded remove list. problem arises when internet connection breaks. when internet connection breaks , comes again thinking of adding images yet uploaded request queue. this can result in more 1 copy of same image saved on server request same image might have gone through before getting rseponse. how can address scenario? i'm not quite sure why you're using service schedule requests volley automatically runs it's request in seperate thread. nevertheless can listen both request results, successful , unsuccessful adding listeners. you can remove image list schedule request using volley. if succeeds can carry on desired, if fails can add again list. public static request getimageuploadrequest(final string image) { response.listener<t> responselistener = new response.listener<t>() { @override public void onresponse(t response...
