c++ 启用visual styles

在C程序中启用Visual Styles需要进行以下步骤：

1. 在程序中添加头文件：#include <windows.h>

2. 在WinMain函数中添加代码：

// 初始化公共控件库
INITCOMMONCONTROLSEX icc;
icc.dwSize = sizeof(INITCOMMONCONTROLSEX);
icc.dwICC = ICC_WIN95_CLASSES;
InitCommonControlsEx(&icc);

// 启用Visual Styles
HMODULE hMod = LoadLibrary(TEXT("uxtheme.dll"));
if(hMod)
{
typedef HRESULT (WINAPI *PFNENABLETHEME)(HWND, LPCWSTR);
PFNENABLETHEME pfnEnableTheme = (PFNENABLETHEME)GetProcAddress(hMod, "EnableThemeDialogTexture");
if(pfnEnableTheme)
{
pfnEnableTheme(NULL, L" ");
}
FreeLibrary(hMod);
}

3. 在程序的资源文件中添加manifest文件，其中包含以下内容：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
<assemblyIdentity version="1.0.0.0" processorArchitecture="*" name="myapp.exe" type="win32"/>
<description>My Application</description>
<dependency>
<dependentAssembly>
<assemblyIdentity type="win32" name="Microsoft.Windows.Common-Controls" version="6.0.0.0" processorArchitecture="*" publicKeyToken="6595b64144ccf1df" language="*"/>
</dependentAssembly>
</dependency>
</assembly>

以上步骤完成后，重新编译程序即可启用Visual Styles。
