vb.net - Writing to Text Box keeps failing - Visual Basic 2010 -


apologies if easy mistake, quite new vb not sure going wrong. code produces results written textboxes @ end of process. code have @ moment:

public class form1     public sub buttoninput_click(byval sender system.object, byval e     system.eventargs) handles buttoninput.click         try             'information irrelevant question here..              mainmethod.main()              textboxbf.appendtext(bestglobalfitness.tostring("f4"))             textbox0.text = bestglobalposition(0)             textbox1.appendtext(bestglobalposition(1).tostring("f4"))             textbox2.appendtext(bestglobalposition(2).tostring("f4"))             textbox3.appendtext(bestglobalposition(3).tostring("f4"))             textbox4.appendtext(bestglobalposition(4).tostring("f4"))             textbox5.appendtext(bestglobalposition(5).tostring("f4"))             textbox6.appendtext(bestglobalposition(6).tostring("f4"))          catch ex indexoutofrangeexception             console.writeline("indexoutofrangeexception caught")         end try     end sub end class

as can see, have tried both textbox.text , textbox.appendtext methods neither appear working. odd first line textboxbf.appendtext(bestglobalfitness.tostring("f4")) work..

here how bestglobalposition , bestglobalfitness entered in module:

module mainmethod     public bestglobalfitness double     public bestglobalposition([dim] - 1) double public sub main()     try         dim bestglobalposition([dim] - 1) double         bestglobalfitness = double.maxvalue          'rest of method here..          console.write("final best fitness = ")         console.writeline(bestglobalfitness.tostring("f4"))         integer = 0 bestglobalposition.length - 1             console.write("x" & & " = ")             console.writeline(bestglobalposition(i).tostring("f4") & " ")

i can't see going wrong - appreciated!

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)...
