sql - Using comboboxes for choises VB -


i have created own database , want data appear in comboboxes. combobox selections shall guiding towards final value.

so manage populate first combobox using click assignments in visual studios. however, need populate second combobox using choice of first combobox filter.

i'm new in vb , guided visual studios, feel don't find population of first combobox takes place. there's piece of code saying

    me.table1bindingsource.datamember = "table1"     me.table1bindingsource.datasource = me.databasdataset     me.table1tableadapter.fill(me.databasdataset.table1)     me.combobox1.datasource = me.table1bindingsource     me.combobox1.displaymember = "production technology"     me.combobox1.formattingenabled = true     me.combobox1.location = new system.drawing.point(265, 67)     me.combobox1.name = "combobox1"     me.combobox1.size = new system.drawing.size(317, 21)     me.combobox1.tabindex = 29     me.combobox1.valuemember = "production technology"

which guess uses sql code table1 defined graphical interface.. looks : (select distinct [production technology] [table]).

now, thing table, contains whole database, including lot of duplicate [production technology] , [reactor type]. want way read selected choise in combobox1 (which should combobox1.selectedvalue?) , create table2 [reactor type] has same value [production technology] chosen in combobox1.

is question understanable? 1 of difficulties of code made coding, while weird stuff don\t understand autogenerated clicks... can't show code have, since don't find :s

combobox1 populated line me.combobox1.datasource = me.table1bindingsource

the values shown in combobox1 determined line me.combobox1.valuemember = "production technology"

the selected value chosen in line me.combobox1.valuemember = "production technology"

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
