javascript - Using document.getElementById() in IE 9 and previous versions -


this question has answer here:

i have web page used upload file. there 2 input fields on form. 1 of type text used give file name in our database. other of type file select file upload.

<input type="text" name="docname" id="docname" size="35" value="" /> <input type="file" name="importfile" id="importfile" size="35" onchange="refreshfilename();"/>

i want use javascript extract actual file name (minus file path) "importfile" field once it's selected , auto-populate field "docname" value. javascript looks this:

function refreshfilename(){ var filename = document.getelementbyid('importfile').value;   var str = filename.split("\\"); var length = str.length;  document.getelementbyid('docname').value = str[length-1];  }

this seems work file in chrome, firefox , ie 10 or 11. doesn't seem work in ie 9 or earlier versions. nothing have tried seems solve problems. suggestions on how can work earlier version of ie (i've thought of idea "just tell users not use ie").

if problem you're getting full path in ie, try this:

var filename = document.getelementbyid("importfile").value; document.getelementbyid('docname').value = filename.match(/[^\/\\]+$/);

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)...
