vb.net - How do i link Visual Studio applications over LAN -


i have created vs application , have installed copy on computer , wish link them via lan if settings canged in 1 , others setings saved .

for example setting

i created new name in sttings , call "adminin" , set type integer , scope user , set value 0

    dim ai new .mysettings   private sub button1_click(sender object, e eventargs) handles button1.click      ai.adminin = ai.adminin + 1 ai.save()  end sub

now how can ai updated in other application on other computer .

how connect via lan , accomplish ?

i found link provides example code modify application-scoped variables my.settings might useful. i've tested out simple form timer , label showing me current value of adminin setting, , seems work. timer updates label on every instance of form checking reloaded my.settings value. variable need application scoped in order accessible users on machine may run executable.

http://www.codeproject.com/articles/19211/changing-application-scoped-settings-at-run-time

here's form code put keep current admin count up-to-date. simplistic, seems job neatly.

public class form1      private sub form1_formclosing(byval sender object, byval e system.windows.forms.formclosingeventargs) handles me.formclosing         'decrement adminin count when current instance of form closed.         me.tmradmincheck.stop()         changemyappscopedsetting((my.settings.adminin - 1).tostring)         'reload .exe.config file synchronize current adminin count.         my.settings.reload()         my.settings.save()     end sub      private sub form1_load(byval sender system.object, byval e system.eventargs) handles mybase.load         'increment current adminin count when new instance of form loaded         changemyappscopedsetting((my.settings.adminin + 1).tostring)         'reload .exe.config file synchronize current adminin count.         my.settings.reload()         my.settings.save()          me.lbladminsin.text = "current admins in: " & my.settings.adminin.tostring         'start timer periodically check adminin count my.settings         me.tmradmincheck.enabled = true         me.tmradmincheck.interval = 100         me.tmradmincheck.start()         me.refresh()         application.doevents()     end sub      private sub tmradmincheck_tick(byval sender system.object, byval e system.eventargs) handles tmradmincheck.tick         'reload .exe.config file synchronize current adminin count.         my.settings.reload()         me.lbladminsin.text = "current admins in: " & my.settings.adminin.tostring         me.refresh()         application.doevents()     end sub end class

i've found couple of things method, , relate others have mentioned in comments:

  1. the application's .exe.config file must in accessible location (the codeproject example defaults application's executable directory). of course, save settings ini file or other configuration file in shared directory , accomplish similar thing, method uses my.settings.
  2. you'll may want additional checking possibility of 2 people attempting in @ same time. if happens, configuration file still open , locked, , new adminin value won't saved. codeproject example doesn't have exception handling, work functionality exception handling making recursive call sub.

otherwise, seems totally viable method of accomplishing you're talking about.

php - Calling a template part from a post -

i include iframe within post in wordpress. located inside content of post, meaning cannot in post template file, otherwise either before or after. i'd add facebook plugin within posts: <div id="socialwrap"><div class="fb-like" data-href="http://onlinearizonahomes.info" data-send="true" data-width="450" data-show-faces="true" data-font="arial"></div></div> i thinking of calling template part within post <?php get_template_part( 'social' ); ?> cannot use php within post without plugin (i'd avoid using plugin this). an alternative using javascript create html in post, seems unnecessary use of javascript. what best way add html within wordpress post? you can use shortcode. add functions.php function cudjex_fbshare( $atts, $content = null ) { global $post; $link = get_permalink($post->id); return '<div id="socialwrap...
