If m1, m2, x1, x2, y1, y2 are known then using this formulae you can find them X = [(2*y1)/(m2-m1)] – [(2*m1*x1)/(m2-m1)] + [(m1*x1)/(m2-m1)] + [(m2*x2)/(m2-m1)] + [(y1+y2)/(m2-m1)] and for y: Y = [(y1+y2)/2] + [(m1+m2)*X/2] – [(m1*x1)/2] – [(m2*x2)/2] Note: In the formula for Y appears X, but if you compute it before it … Read more
So you are getting access voilation…. The problem is that your buffers are probably overflowing and you have no length check in your code… The buffers you have allocated are only 25 bytes long char str1[25], str2[25]; so to intruduce a length check, add an extra parameter to concat which tells how long the output … Read more
Keep a local variable and set it to the appropriate button’s id whenever a button is pressed. int lastPressedButton; … @Override public void onClick(View v) { lastPressedButton = v.getId(); switch(v.getId()) { // normal button handling code } } 0 solved How to know which Button was pressed recently among all the Buttons in an activity?
I do not know whether this solution is more efficient, but maybe it is more readable and easier to code: #include <iostream> #include <cstdlib> int main() { const int magicNumber = 32640; const int maxOffset = 1920; int n; std::cin >> n; int y = 20; const std::div_t divresult = std::div(n, magicNumber); if (divresult.rem > … Read more
Here’s how I would find the answer. After each fork(), I would print the current process ID. When I run the program, I would note all of the unique process IDs, and that would tell me how many processes existed: This is my program: #include <stdio.h> #include <unistd.h> int main() { /* fork a child … Read more
I would suggest something like this: /\) (?!.*\))(\S+)/ rubular demo Or if you don’t want to have capture groups, but potentially slower: /(?<=\) )(?!.*\))\S+/ rubular demo (?!.*\)) is a negative lookahead. If what’s inside matches, then the whole match will fail. So, if .*\) matches, then the match fails, in other terms, it prevents a … Read more
Treating this as a kind of code-golf, the following gives an idea as to how you can approach the problem from a functional mindset, where you try and ‘flow’ the results of one function through another (which is presumably what your manager is after). Some changes are possible: Replacing the if with a filter predicate … Read more
Do you just want to code the table up? Would something like this suffice?: PCP <- c(0, 4.9, 5, 9.9, 10, 14.9, 15) seq2max <- seq(0,max(PCP)+5,5) result <- data.frame(min=seq2max,max=seq2max+4.9,DRI=seq_along(seq2max)-1) min max DRI 1 0 4.9 0 2 5 9.9 1 3 10 14.9 2 4 15 19.9 3 5 20 24.9 4 result$DRI # [1] … Read more
You are looking for Map Overlay MKOverlayView. Check these tutorials: Overlay View Image Overlay Creating overlay Creating a MKOverlayView Create a subclass of MKOverlayView like: .h #import #import @interface MapOverlayView : MKOverlayView { } @end .m #import “MapOverlayView.h” @implementation MapOverlayView – (void)drawMapRect:(MKMapRect)mapRect zoomScale:(MKZoomScale)zoomScale inContext:(CGContextRef)ctx { UIImage *image = [UIImage imageNamed:@”yourImage.png”]; CGImageRef imageReference = image.CGImage; MKMapRect … Read more
Something like this might work. I’m not sure on the efficiency yet – it may depend on the amount of hits that you’re looking for: create type HitBlocks as table ( HitIndex int not null ) go create procedure FindMaxCover @Hits HitBlocks readonly as ;With DecomposedBlocks as ( select (HitIndex/8)+1 as ByteIndex,POWER(2,(HitIndex%8)) as BitMask from … Read more
It is simple: Address = Address.concat(String.valueOf(i)); Address initailly had a whatever value: 5.20.86.0. In your for loop you are appending the i current value, but you don’t delete the previous value! So it is going to 5.20.86.012345678910 as 5.20.86. and 012345678910 than 012345678910 11 12 13 14 and so on. I hope it is a … Read more
I found that the XAML content that I read from the file contained BOM. I BOM is stripped out, the XAML code is parsable. I use Visual Studio 2010. The “Text Visualizer” in debugging mode did not show any sign of BOM (the XAML string is in UTF8). But when I accidently copied the text … Read more
You can use replace : var url2 = url.replace(/&c=[^&]+/,”) 2 solved Regex to remove a hash-parameter from the urls hash
Use .siblings() (function($){ // REMAP “$” to jQuery $(function(){ // DOM READY shorthand $(“li”).click(function(){ $(this).slideDown(800).siblings().slideUp(800); }); }); })(jQuery); or in your case might be this (I don’t know as it’s a bit unclear) $(“li”).click(function(){ $(this).find(‘.step’).slideToggle(800); $(this).siblings().find(‘.step’).slideUp(800); }); jQuery API Documentation – Siblings 2 solved target children elements but not the ones of the clicked one … Read more
You can inflate its views by doing: LayoutInflater inflater = (LayoutInflater)context.getSystemService (Context.LAYOUT_INFLATER_SERVICE); inflater.inflate(…); Alternatively, you can simply create a view like final LinearLayout l = […] //add stuff l.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT)); //etc… solved XML to Java code in Android [closed]
