powershell - Convertto-HTML outputting pre/post content showing up as System.String[] instead of actual content -

-

i trying use powershell output table pre/post content , email it, pre/post content showing in email "system.string[]." rest of content seems fine, , if output html string console, looks fine.

function send-smtpmail($to, $from, $subject, $smtpserver, $body) {     $mailer = new-object net.mail.smtpclient($smtpserver)     $msg = new-object net.mail.mailmessage($from,$to,$subject,$body)     $msg.isbodyhtml = $true     $mailer.send($msg) }  $content = get-process | select processname,id $headerstring = "<table><caption> foo. </caption>" $footerstring = "</table>" $myreport = $content | convertto-html -fragment -precontent $headerstring -postcontent $footerstring  send-smtpmail "my email" "from email" "my report title" "my smtp server" $myreport

shows in email as:

system.string[] processname id ...             ... system.string[]

doing out-file , invoke-item has same results sending email...

convertto-html returns list of objects - strings , string arrays e.g.:

407# $headerstring = "<table><caption> foo. </caption>" 408# $footerstring = "</table>" 409# $content = get-date | select day, month, year 410# $myreport = $content | convertto-html -fragment -precontent $headerstring `                                            -postcontent $footerstring 411# $myreport | foreach {$_.gettype().name} string[] string string string string string string string string string string[]

so $myreport contains array of both strings , string arrays. when pass array mailmessage constructor, expects type string, powershell attempts coerce string. result is:

412# "$myreport" system.string[] <table> <colgroup> <col/> <col/> <col/> </colgroup> <tr><th>day </th><th>month</th><th>year</th></tr> <tr><td>9</td><td>2</td><td>2011 </td></tr> </table> system.string[]

the easy solution run output of converto-html through out-string cause $myreport single string:

413# $myreport = $content | convertto-html -fragment -precontent $headerstring `                                            -postcontent $footerstring |                             out-string 414# $myreport | foreach {$_.gettype().name} string

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,...

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....
