i've found great example here: https://developers.google.com/analytics/solutions/articles/data_over_time uses google.gdata, not google.api. credentials asking following: private static final string username = "username"; private static final string password = "password"; private static final string table_id = "table_id"; whereas in google.api, credentials needed following: private static final string key_file_location = "yourfile.p12"; private static final string service_account_email = "something@developer.gserviceaccount.com"; these 2 libraries (google.api , google.gdata) seem able similar things in fact different. meant username, password , table_id in first scenario? recommended java api google analytics? it recommended use google analytics java client libraries . example have pointed uses deprecated client login . you should use updated hello analytics api tutorial better example of using java api googl...

i realize reading .csv file removes leading zeros, of files, maintains leading zeros without having explicitly set colclasses in read.csv. on other hand, what's confusing me in other cases, remove leading zeros. question is: in cases read.csv remove leading zeros? the read.csv , read.table , , related functions read in character strings, depending on arguments function (specifically colclasses , others) , options function try "simplify" columns. if enough of column looks numeric , have not told function otherwise, convert numeric column, drop leading 0's (and trailing 0's after decimal). if there in column not number not convert numeric , either keep character or convert factor, keeps leading 0's. function not @ entire column make decision, may obvious not being numeric may still converted. the safest approach (and quickest) specify colclasses r not need guess (and not need guess r going guess).

the files right click on target platform in project manager , select "add platform", when "add platform" item greyed out. is there way add 64 bit platform? this happen when migrating projects previous versions of delphi. try deleting dproj file , open dpr file. way handles upgrade process. if not, need create new project , add existing source files it. or can try editing dproj file enable win64 platform. <project xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> <propertygroup> ... <targetedplatforms>3</targetedplatforms> ... </propertygroup> ... <propertygroup condition="('$(platform)'=='win64' , '$(base)'=='true') or '$(base_win64)'!=''"> <base_win64>true</base_win64> <cfgparent>base</cfgparent> <base>true</base> </propert...
