问题 I've found a way to create virtual desktops with c#. Now I was wondering if we can take a screenshot of a particular desktop and if so how ? Thanks in advance Blizz 回答1: HAve you tried the CopyFromScreen method in the GFX Object Graphics g = new Graphics(); g.CopyFromScreen( ....params.... ) 回答2: I haven't tried it but the first thing I'd try is: create a new thread switch the thread to the new desktop by calling SetThreadDesktop take a screen shot switch thread back might just work. 来源：

Capture Console in Delphi 2009 and above

问题 The code below works for Delphi XE, but the 2400 buffersize is pretty ugly. Anyone have some suggestions on cleaning this routine up ?? And making the 2400 limit disappear (without defining a 64000 buffer). Thanks procedure TForm1.Button1Click(Sender: TObject); begin CaptureConsoleOutput('c:\windows\system32\ipconfig','',Memo1); end; procedure TForm1.CaptureConsoleOutput(const ACommand, AParameters: String; AMemo: TMemo); const CReadBuffer = 2400; var saSecurity: TSecurityAttributes; hRead:

How can I capture another process's output using C?

问题 How can I capture another process's output using pure C? Can you provide sample code? EDIT: let's assume Linux. I would be interested in "pretty portable" code. All I want to do is to execute a command, capture it's output and process it in some way. 回答1: There are several options, but it does somewhat depend on your platform. That said popen should work in most places, e.g. #include <stdio.h> FILE *stream; stream = popen("acommand", "r"); /* use fread, fgets, etc. on stream */ pclose(stream)

Can't capture a static variable in a lambda [duplicate]

由 醉酒当歌 提交于 2020-01-14 12:41:27
问题 This question already has answers here : Capturing a static variable by reference in a C++11 lambda (2 answers) Closed last month . This seems strange, I can capture the static variable, but only if the variable isn't specified in the capture list, i.e., it implicitly captures it. int main() { int captureMe = 0; static int captureMe_static = 0; auto lambda1 = [&]() { captureMe++; }; // Works, deduced capture auto lambda2 = [&captureMe]() { captureMe++; }; // Works, explicit capture auto

二维码的生成和扫描

由 柔情痞子 提交于 2020-01-14 06:01:23
二维码已经是很成熟的应用了,正好这次的应用用到二维码开发,自然而然地用第三方的ZXing,遇到不少坑,主要就是ZXing的扫码,差评!最后用AVFoundation实现,很容易的功能,我还是太天真了,不知道ZXing/ObjC是怎么骗到靠2000个星星的. ZXing 公司产品要实现二维码功能,这个早已成熟的功能第一想法肯定是用第三方的,github上一查,ZXing的星星最多,那就它了. 把整个项目copy下来先demo跑起来,下了好久,100多M啊,真大.但其实用不到那么多的,对于只需要生成,扫描二维码,只需要: pod 'ZXingObjC/QRCode' 二维码生成 ZXEncodeHints *hints = [ZXEncodeHints hints]; hints.encoding = NSUTF8StringEncoding; hints.margin = @(0); ZXQRCodeWriter *writer = [[ZXQRCodeWriter alloc] init]; ZXBitMatrix *result = [writer encode:url format:kBarcodeFormatQRCode width:200*[UIScreen screenScale] height:200*[UIScreen screenScale] hints:hints

using Windows Media Encoder to record screen

问题 Is it easy to write some .Net code to record screen and audio (from computer mic), then output to an wmv file. Any reference code? BTW: I searched all codes from WME SDK, no such sample code. thanks! George 回答1: Microsoft and the content mafi^H^H^H^Hindustry are trying their best to make this impossible. You will be far better of searching for "open source screen audio capture" than browsing any officially supplied documentation/example code - I would be seriously surprised if Microsoft
