c# - How do I use Resource File/Path on [ToolboxBitmap("MyResourcePictureFileName")] -


developing custom control , want place custom icon. trying use solution resource file within [toolboxbitmap("myresourcepicturefilename")] property icon not setting instead showing default user control icon. whereas fixed path works fine

e.g. [toolboxbitmap( @"c:\frame.bmp")]

but don't want use absolute location.

question: how can use custom image/icon of control

here code:

note: frame.bmp in resource , action property=embedded resource build

// dont want use --> [toolboxbitmap( @"c:\frame.bmp")]   [toolboxbitmap("resources.frame.bmp")] [toolboxitem(true)]  public partial class mycustompanelcontrol : panel { ................ ................ }

please advice,

thanks

   [toolboxbitmap("resources.frame.bmp")]

the resource name not correct, pretty chronic problem toolbox bitmaps btw. first make sure embedded bitmap correctly, not use resource designer:

  • project > add existing item > select bitmap file
  • select added item in solution explorer window. in properties window set build action "embedded resource"
  • project > properties > application tab > default namespace property matters, that's name use instead of "resources"
  • double-check , run ildasm.exe. double-click manifest, should see entry resembles:
.mresource public defaultnamespace.frame.bmp {   // offset: 0x000000b8 length: 0x000004f6 }

note .mresource name, that's 1 put in attribute. fix:

[toolboxbitmap("defaultnamespace.frame.bmp")]

replacing "defaultnamespace" actual name.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
