How to limit number of transposed variables in proc transpose SAS -


i transposing file several million observations using 

proc transpose data=click out=click_transp name=test prefix=var; comlogid;         var clickthrulink_description; run;

however, job takes long time run because of clickthrulink_description have hundreds of observations. need limit transposed variable down 6. there way in sas , more efficient in terms of run time?

you have few options.

first off, use keep statement in output.

proc transpose in=have out=want(keep=id col1-col6); id; var myvar; run;

this limit what's written output dataset, limit size greatly.

you use options compress=yes; bigger issue - lots of blank data. decrease amount of size needed store observations fewer maximum number of columns.

finally, limit things view:

data v_have/view=v_have; set have; id; if first.id counter=0; counter+1; if counter<6; run;  proc transpose data=v_have out=want; id; var yourvar; run;

that pass first 6 observations per id transpose procedure.

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)...
