只是尝试从PHPBench.com保存和修复源代码
并点击此错误(该网站已关闭,作者没有回答问题).这是来源:
<?php

Qt是使用ANGLE构建的,它只在DirectX 9.0c之上提供OpenGL ES 2.0
此示例要求使用-opengl桌面配置Qt
搜索他们的维基但没有找到我该怎么做来解决它:(
有人想要更多关于那个吗？
最近设法在测试程序中使用libcurl来下载文件.代码是这样的:
CURL * curl;
FILE * fout;
CURLcode result;
char * url = "http://blablabla.com/blablabla.txt";
char filename[FILENAME_MAX] = "blablabla.txt";
curl = curl_easy_init();
if (curl)
{
fout = fopen(filename,"wb");
curl_easy_setopt(curl, CURLOPT_URL, url);
curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, write_data);
curl_easy_setopt(curl, CURLOPT_WRITEDATA, fout);
result = curl_easy_perform(curl);
curl_easy_cleanup(curl);
fclose(fout);
}
以及指令的那些东西:
#define CURL_STATICLIB
#include <curl/curl.h>
我的问题是如何使我不需要在exec中将所有dll复制到同一目录中以使其工作:
libcurl.dll
libeay32.dll
libidn-11.dll
librtmp.dll
libssh2.dll
libssl32.dll
zlib1.dll
无法在库的主页(http://curl.haxx.se)中找到有关该信息的信息:|

const …在我的C#练习中遇到了另一个问题.这是对它的简短解释:在Program.cs中我有以下代码:
namespace testApp
{
public class AppSettings
{
public static int appState { get; set; }
public static bool[] stepsCompleted { get; set; }
}
public void Settings
{
appState = 0;
bool[] stepsCompleted = new bool[]{false, false, false, false, false};
}
}
static class MyApp
{
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new gameScreen());
AppSettings appSettings = new AppSettings();
}
}
这是在Form1.Designer.cs中:
namespace testApp
{
private void InitializeComponent() {..}
private void detectPressedKey(object sender, KeyPressEventArgs e)
{
if (e.KeyChar == …刚尝试创建ArrayList并用对象填充它,但是遇到了这个错误:
无法创建静态类'diamondmine.MyObject'的实例
到目前为止的代码:
public static class MySettings
{
//some lines
public static ArrayList myObjects { get; set; }
static MySettings()
{
//some lines
myObjects = new ArrayList();
}
}
public static class MyObject
{
public static int a { get; set; }
public static int b { get; set; }
static MyObject()
{
a = 1;
b = 2;
}
}
这就是我尝试添加新对象的方式:
//some code
MySettings.myObjecs.Add(new MyObject());
//more code
Rly没有线索问题在哪里,我正在做MSDN中写的东西:(
