Defined in header <string.h> char * strstr ( const char * str , const char * substr ) ; Finds the first occurrence of the null-terminated byte string pointed to by substr in the null-terminated byte string pointed to by str . The terminating null characters are not compared. The behavior is undefined if either str or substr is not a pointer to a null-terminated byte string. Parameters str - pointer to the null-terminated byte string to examine substr - pointer to the null-terminated byte string to search for Return value Pointer to the first character of the found substring in str , or NULL if no such substring is found. If substr points to an empty string, str is returned. Example # include <string.h> # include <stdio.h> void find_str ( char const * str , char const * substr ) { char * pos = strstr ( str , substr ) ; if ( pos ) { printf ( "found the string '%s...

Answer : When using observe:response , don't type the call ( post<Blob>(...) ), as the returned Observable will be of HttpResponse. So this should work: this.httpclient.post('MyBackendUrl', params, {observe: 'response', responseType: 'blob'} ); Why this happens, is there's two versions of the post method, one with a generic type, one without: /** * Construct a POST request which interprets the body as JSON and returns the full event stream. * * @return an `Observable` of all `HttpEvent`s for the request, with a body type of `T`. */ post<T>(url: string, body: any | null, options: { headers?: HttpHeaders | { [header: string]: string | string[]; }; observe: 'events'; params?: HttpParams | { [param: string]: string | string[]; }; reportProgress?: boolean; responseType?: 'json'; withCredentials?: boolean...

Answer : You can use filters with -webkit-filter and filter : Filters are relatively new to browsers but supported in over 90% of browsers according to the following CanIUse table: https://caniuse.com/#feat=css-filters You can change an image to grayscale, sepia and lot more (look at the example). So you can now change the color of a PNG file with filters. body { background-color:#03030a; min-width: 800px; min-height: 400px } img { width:20%; float:left; margin:0; } /*Filter styles*/ .saturate { filter: saturate(3); } .grayscale { filter: grayscale(100%); } .contrast { filter: contrast(160%); } .brightness { filter: brightness(0.25); } .blur { filter: blur(3px); } .invert { filter: invert(100%); } .sepia { filter: sepia(100%); } .huerotate { filter: hue-rotate(180deg); } .rss.opacity { filter: opacity(50%); } <!--- img src http://upload.wikimedia.org/wikipedia/commons/thumb/e/ec/Mona_Lisa%2C_by_Leonardo_da_Vinci%2C_from_C2RMF_retouched.jpg/500px-M...

Answer : The only short circuiting (of a sort) is within Case expression evaluation, so the following ungainly statement does what I think you're asking; Select Case True Case (myObject Is Nothing), Not myObject.test() MsgBox "no instance or test == false" Case Else MsgBox "got instance & test == true" End Select End Sub This is an old question, but this issue is still alive and well. One workaround I've used: Dim success As Boolean ' False by default. If myObj Is Nothing Then ' Object is nothing, success = False already, do nothing. ElseIf Not myObj.test() Then ' Test failed, success = False already, do nothing. Else: success = True ' Object is not nothing and test passed. End If If success Then ' Do stuff... Else ' Do other stuff... End If This basically inverts the logic in the original question, but you get the same result. I think it's a cleaner solution t...

Answer : Normalization with removal of spaces before and after label names and removing of empty entries. The following example uses the comma parser of package kvsetkeys for parsing the label name list of the referencing commands of package cleveref . The internal \@cref with the list in its second argument is redefined for this: \documentclass{article} \usepackage{cleveref} \usepackage{kvsetkeys} \makeatletter \let\org@@cref\@cref \renewcommand*{\@cref}[2]{% \begingroup \toks@={}% \comma@parse{#2}\add@cref@item \edef\process@me{\endgroup \noexpand\org@@cref{#1}{\the\toks@}% }\process@me } \newcommand*{\add@cref@item}[1]{% \expandafter\ifx\expandafter\\\the\toks@\\% \toks@{#1}% \else \toks@\expandafter{\the\toks@,#1}% \fi } \makeatother \begin{document} \noindent We can use \cref{1,2}, and now \cref{1, 2},\\ and even with a leading or trailing comma: \Cref{ , 1 , 2 ,}. \section{Section 1} \label{1} \section{Section ...

Answer : I think the least-recent time machine snapshots was corrupted - potentially from some system crashes caused by APFS bugs. I tried running DIsk Utility's first aid, but that froze my computer for over 3 hours (maybe it ran out of space to work with?) - I ended up having to force-restart. I solved the problem by running first aid booted from an external hard drive install of High Sierra. It removed some old snapshots. I then was able to boot from my normal drive and run tmutil deletelocalsnapshots... which successfully deleted the snapshots and freed up space Great solution detecting that the filesystem was corrupt when the normal commands were note working. Also note, you can avoid iterating on the list of snapshots and just direct the system to reclaim space up to and surpassing the limit you choose: tmutil thinlocalsnapshots / $(echo "5 * 1000000000" | bc) 2 The above command asks for 5 GB of cleaning. I chose the echo math to make it easy to dial u...

Answer : To write the best code, you "should" use the latter approach, with a function reference: var refreshId = setInterval(function() {}, 5000); or function test() {} var refreshId = setInterval(test, 5000); but your approach of function test() {} var refreshId = setInterval("test()", 5000); is basically valid, too (as long as test() is global). Note that there is no such thing really as "in jQuery". You're still writing the Javascript language; you're just using some pre-made functions that are the jQuery library. First of all: Yes you can mix jQuery with common JS :) Best way to build up an intervall call of a function is to use setTimeout methode: For example, if you have a function called test() and want to repeat it all 5 seconds, you could build it up like this: function test(){ console.log('test called'); setTimeout(test, 5000); } Finally you have to trigger the function once: $(document).re...
