unix - How do I send and receive real-time signals `sigqueue()` in Python? -

पायथन एक संकेतों मॉड्यूल और os.kill प्रदान करता है; क्या इसकी sigqueue () (संलग्न डेटा के साथ वास्तविक समय के संकेत) की सुविधा है? विकल्प क्या हैं?

आप इसे

 > के साथ कर सकते हैं ; & gt; & gt; सीटीआईपी आयात से * & gt; & gt; & gt; C = cdll.LoadLibrary ("libc.so.6") & gt; & gt; & gt; C.sigqueue & lt; _FuncPtr ऑब्जेक्ट 0xb7dbd77c & gt; & Gt; & gt; & gt; C.sigqueue (100, 10, 0) -1> gt; & gt;  

आपको सीटीआईपी में एक संघ बनाने के बारे में देखना होगा जो मैंने पहले कभी नहीं किया है, लेकिन मुझे लगता है कि संभव है।

Remove Characters from the end of a String Scala -

What is the easiest way to remove the last character from the end of a string in scala?

I think there are some very useful methods in the Ruby string class like Cut I used "odononets". Ideopation in Scala, but it's collapsed. I do not want to go to the extreme premises:

  string.slice (0, string.length - 1)  

Please tell me there this normal form There is a simple method like cutting for anything.

Regarding using the drop-down, which works in 2.8: -

< Pre> "abc!". DropRight (1)

which produces "abc"

cocoa - Objective C Printing: How to set header content? -

I want to print a specific NSView. When I do this, I want to add content to the header of the print page.

For example, if a cat's picture is in the NSV, when I suppress the print, the print preview appears with the cat's picture I want the print to be a cat's picture form In, with caption: "Cat" in the title, which I do not want to appear on the original NSV.

In addition, if this is possible, then

thanks!

You can overwrite the method - (NSAttributedString *) page header See document in the code> NSView subclasses

Note that the headers are generated only when the user is in default with the key NSPrintHeaderAndFooter value.

For images, they can be added using an NSAttributedString using a NSTextAttachment .

C++ overloading * for polynomial multiplication -

So I am developing a polynomial square where a user input: 1x ^ 0 + 2x ^ 1 + 3x ^ 2 .. and 1,2,3 (coefficient) are stored in an integer array

My overloaded + and - functions work, however, * does not work. It does not matter, it always shows- 842150450
when should be (5x ^ 0 + x ^ 1) * (-3x ^ 0 + x ^ 1) = -15x ^ 0 + 2x ^ 1 + 1x ^ 2 or (x + 5) (x-3) = x ^ 2 + 2x - 15

I am using overloaded * functions such as: polynomial times = one two;
I am guessing the problem strtol (p; and endptr, 10) because it uses a long int, nevertheless, adding and subtracting tasks completely

My constructor

  polynomial :: polynomial (four * s) {char * string; String = new four [Stellen (s) + 1]; Int length = Stellen (string); Streakpie (string, s); Four * copy; Copy = new four [length]; Strcpy (copy, string); Char * p = strtok (string, "+ -"); Counter = 0; While (P) {P = Strokec (NULL, "+ -"); Counter ++; } Coefficient = New Int [Counter]; P = stroke (copy, "+"); Int a = 0; While (p) {long interval coeff; Char * endptr; Coeff = strtol (p, end, 10); // first stops in non-number if (* p == 'x') coeff = 1; Coefficient [a] = coffe; P = stroke (faucet, "+"); One ++; }}  

and overloaded * function

  Polynomial Multilateral :: Operator * (Cost Polymic and Write) {Multilayer Temporary; // coefficient the array array int count = (counter + right.counter) - 1; Temp.counter = count; Temp.coefficient = new int [count]; For (int i = 0; i  

and reads my whole code:

To zero in the operator, temp.coefficient [i + j] is not visible to start . .

  temp.coefficient = new int [count]; Std :: memset (temp.coefficient, 0, count * sizeof (int));  

winforms - C# Printing Inconsistent -

I have a form on which I have many text boxes I print text from these text boxes in those places I want to where they are on the farm. It's printing using the code below at the moment. However, the text prints separately on different printers (on some it is just right, something is too much, etc.). It is being printed on the pre-printed form with the blank space for the text, so it should be quite accurate, what am I missing to print it on every printer?

  Public Zero Print DevicePropage (Object Sender, PrintPageEventArgs e) {Panel Curpanel = this.FormPanel; Graphics G = (graphics) e.Graphics; Pen apien = new pen (brush black, 1); // Set the cycle through each control, whether it is a checkbox or text box and inside // inside the information, then come to the place xLocation, yLocation; For (int j = 0; j & lt; curPanel.Controls.Count; j ++) {// Check whether there is a text box type by comparing one of the types of text boxes, if (curpanel.Controls [ J] is a text box) {/ Unbox the textbox text box TheText = (text box) curPanel.Controls [j]; // Draw a text box string on the condition of the text box on the form, scale to print page xLocation = theText.Bounds.Left; YLocation = theText.Bounds.Top; G. Drawstring (text, text, fonts, brushes black, x lockation, y lotion); }}}}  

The problem is how are you aligning the controls inside . The default alignment is approximately equal to StringFormat.Anignment = StringAlignment.Center, it can be changed to the button and check the box with your TextAlign property. You must use a drawer () surcharge which takes a rectangle and string formatting. Note that the text box is difficult, so you can also close some pixels.

Take a look at Control.DrawToBitmap () for a completely different approach.

internet explorer - What is this IE CSS bug called? (Double vertical padding) -

(Note, this is not a double margin bug. I'm saying this double-vertical-padding bug then Unless there is no more clever / documented name for this?)

Just when I thought I saw all the false IE CSS bugs, I have done a simple test The case that continues to mislead me looks down the page and works great in FF, Opera, et al though, IE 6 and IE7 seems to be confused. I will let the document given below speak for itself.

Edit: I have put it at the following URL:
Open it in IE and compare it again in FF.

My question is: What is this bug called? (Did I miss it somewhere? Has it been found?) I am familiar with the 3px jog bug and double- (horizontal) -margin bugs and many other float-related bugs ... but the vertical padding is being repeated ? (And to the wrong place, to boot.)
