问题 I have been using Blitz array package last few days. During debug I require to print the array contents, and blitz supports something like below std::cout<<blitz_array_name<<std::endl I would like to print the array contents via GDB during debug. So i wrote overloaded functions for different type of arrays which I like to prin, like below void printBlitz(blitz::Array<bool, 1> &in) { std::cout<<in<<std::endl; } void printBlitz(blitz::Array<int, 1> &in) { std::cout<<in<<std::endl; } ... and so

问题 I used this link and added lots of enhancements related to GDI. https://github.com/microsoft/Windows-driver-samples/tree/master/print/OEM%20Printer%20Customization%20Plug-in%20Samples/C%2B%2B/bitmap The above samples generates a bitmap driver with output as a bitmap image. Now using the bitmap I am able to generate working PCL for monochrome. I need some help for enhancing it further to generate PCL for 16bpp, 24 color and gray scale Can anyone suggest some samples where I could see the PCL

问题 def on_printer_button_clicked(self, button): for i in range(len(self.printer_buttons)): if button == self.printer_buttons[i]: pHandle = win32print.OpenPrinter(self.printers[i]['pPrinterName']) win32print.DeletePrinter(pHandle) return So all I'm doing is opening the printer handle and calling the function Delete Printer, as you can see. Here's what I get in the console when I run the function: uninstall_windowGUI.py", line 57, in on_printer_button_clicked win32print.DeletePrinter(pHandle)

问题 I have a Django management command that does quite a bit of processing, so I have it outputting its progress as a percentage. I'd like to use a technique as described in the answers here or here. I'm aware from the Django docs that sys.stdout needs to be replaced with self.stdout when used inside a management command, but I'm still having no luck. It's python 2.7, so I can't give the end kwarg to print . Here's one of the things I've tried in handle of the Command object: i = 0 for thing in

问题 I am trying to print the variable whenever the variable $PrinterStatus is returning any data but the correct data is not coming with If else logic. $CurrentTime = Get-Date $PrinterStatus= Get-Printer -ComputerName "TGHYT-6578UT" | Foreach-Object { $Printer = $_ $Printer | Get-Printjob | Where-Object {$_.jobstatus -ne "Normal" -and $_.SubmittedTime -le $CurrentTime.AddHours(-1) } | Select-Object @{name="Printer Name";expression={$_.printerName}}, @{name="Submitted Time";expression={$_

问题 Rust allows formatted printing of variables this way: fn main(){ let r:f64 = rand::random(); println!("{}",r); } But this doesn't work: fn main(){ println!("{}",rand::random()); } It shows up this error: | 31 | println!("{}",rand::random()); | ^^^^^^^^^^^^ cannot infer type for type parameter `T` declared on the function `random` Is it possible to use function return value directly with println! ? 回答1: Rust doesn't know what type rand::random should be, so you can use the turbofish to provide

问题 I have been trying to get the status of a print job using win32print in Python. The status codes provided by win32print don't seem to match the status code for the job in question. I have tried it on different printers but always get the same results. import win32print import subprocess printer_name = win32print.GetDefaultPrinter() print("Printer: %s" % (printer_name)) hPrinter = win32print.OpenPrinter(printer_name) try: hJob = win32print.StartDocPrinter(hPrinter, 1, ("test of raw data", None
