html - How to make a file 'download' when clicked in Windows IE -

-

i have button in form tag generates csv file , prompts download when user clicks it.

when try accomplish in ie, ie tries open file ie shouldn't. want download file.

my html :

<form accept-charset="utf-8" method="post" action="/generate_csv?calc[]total_interest=189.08">   <div style="margin: 0px; padding: 0px; display: inline;"><input name="utf8" value="✓" type="hidden">     <input name="authenticity_token" value="4o1dedofbbdoc3scpnhdaqpptpfm5nittoryqa0au5k=" type="hidden">   </div>   <input id="print_csv" name="commit" value="print csv" type="submit"> </form>

my rails controller :

headers['content-disposition'] = "attachment;" send_data(csv_string,   :type => 'text/csv; charset=utf-8; header=present; disposition=attachment',   :filename => @filename,   :disposition => 'attachment')

any ideas how accomplish this?

i try following. in controller, when generate csv file sending using send_data or send_file. correct? if so, need set disposition 'attachment' instead of sending file or data. example:

send_data @csv, :type => 'text/csv', :disposition => 'attachment', :filename => 'generate_csv.csv'

or

send_file '/path/to.csv', :type => 'text/csv', :disposition => 'attachment'

another thing can modify routes include format. example:

match 'generate_csv.csv' => 'csv#generate_csv'

you can convert post request request this:

<%= link_to "print csv", '/generate_csv?calc[]total_interest=189.08' %>

binding - How can you make the color of elements of a WPF DrawingImage dynamic? -

-
we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing....
