c# - Second eventhandler won't trigger from button -


i have 2 buttons. first button gets drawn code behind. second button gets drawn when first button clicked. works perfectly. when add event when second button gets clicked event won't triggered. can see in code below there btntwo_click function. if put breakpoint on function program won't break. there way trigger event code behind (not using java script)?

here code, use system in table. simple code has same problem in end.

public partial class _default : system.web.ui.page {     protected void page_load(object sender, eventargs e)     {         imagebutton btn = new imagebutton();         btn.command += new commandeventhandler(btnone_click);         form1.controls.add(btn);     }      void btnone_click(object sender, eventargs e)     {         imagebutton btn = new imagebutton();         btn.command += new commandeventhandler(btntwo_click);         form1.controls.add(btn);     }      void btntwo_click(object sender, eventargs e)     {         label lbltest = new label(); //breakpoint         form1.controls.add(lbltest);     } }

you have add second button on page_load or page_init method of page life cycle:

e.g.

protected void page_load(object sender, eventargs e) {     imagebutton btn = new imagebutton();     btn.command += btnone_click;     form1.controls.add(btn);      imagebutton btn2 = new imagebutton();     btn2.command += btntwo_click;     btn2.visible = false;     form1.controls.add(btn2); }  void btnone_click(object sender, eventargs e) {     // second button      form1.controls[2].visible = true; }  void btntwo_click(object sender, eventargs e) {     imagebutton btn2 = (imagebutton)sender;     // }

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).
