asp.net - A generic error occurred in GDI+ when viewing a 1200 Dpi Tiff Image -


i have created tiff viewer , can view tiff images. except when @ high resolution 1200 dpi. there workaround in code causing problem?

 public function gettiffimage(path string, page integer) image           dim ms memorystream = nothing         dim srcimg image = nothing         dim returnimage image = nothing          try             srcimg = image.fromfile(path)             ms = new memorystream()             dim frdim new framedimension(srcimg.framedimensionslist(0))             srcimg.selectactiveframe(frdim, page)             srcimg.save(ms, imageformat.tiff)             returnimage = image.fromstream(ms)         catch ex exception             throw ex                     srcimg.dispose()             gc.collect()             gc.waitforpendingfinalizers()         end try          return returnimage     end function

thanks in advance

in experience error message misleading , it's caused outofmemoryexception. i'd wager you're losing memory because you're failing clean of idisposable objects. understand gc.collect() isn't reliable approach. try putting using blocks in. use c# not vbscript can't give exact syntax in c# it'd this:

using (var srcimg = image.fromfile(path)) {   using (var ms = memorystream())   {     var frdim = new framedimension(srcimg.framedimensionslist(0));     srcimg.selectactiveframe(frdim, page)     srcimg.save(ms, imageformat.tiff)     using (var returnimage = image.fromstream(ms))     {       return returnimage;     }   } }

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)...
