[ATL/WTL]_[初级]_[常用的界面对象操作]

1. 获取指定大小字体

HFONT AppUtil::GetFont(int pixel,bool bold,const wchar_t* font_name)
{
	LOGFONT lf; 
	memset(&lf, 0, sizeof(LOGFONT)); // zero out structure 
	lf.lfHeight = pixel; // request a 8-pixel-height font
	if(bold)
	{
		lf.lfWeight = FW_BOLD;  
	}
	lstrcpy(lf.lfFaceName, font_name); // request a face name "Arial"
	
	HFONT font = ::CreateFontIndirect(&lf);
	return font;
}

2.  使用默认浏览器打开超链接

void AppUtil::OpenUrl(std::string url)
{
	::ShellExecuteA(NULL, "open", url.c_str(),NULL, NULL, SW_SHOWNORMAL);
}

3.  打开文件夹

void AppUtil::OpenFolder(std::wstring output_dir_)
{
	::ShellExecute(NULL, L"explore",output_dir_.c_str(), NULL, NULL, SW_SHOWNORMAL);
}

4.  获取DC的作用Bitmap大小

BITMAP GetDCBitmapSize(HDC hdc)
{
	BITMAP structBitmapHeader;
	memset( &structBitmapHeader, 0, sizeof(BITMAP) );

	HGDIOBJ hBitmap = GetCurrentObject(hdc, OBJ_BITMAP);
	GetObject(hBitmap, sizeof(BITMAP), &structBitmapHeader);
	return structBitmapHeader;
}

5. 设置CComboBox的文本框只读 (20150714)

CEdit edit_text = box->GetWindow(GW_CHILD);
edit_text.EnableWindow(TRUE);
edit_text.SetReadOnly(TRUE);
