如何提取并保存图标资源

作家：徐景周载入示例源码(http://www.csdn.net/cnshare/soft/9/9199.shtm)    　当你想要运用其余运用步调中的美丽图标时，该如何办呢？大概就会用到少许图标索取东西吧！那么，你领会它们是如何实行的，想不想本人发端也做一个符合本人的图标索取东西呢？底下，就让我用我往日做过的一个东西＜轻轻快松抓图标＞来报告你吧！它不妨索取百般文献中的图标资源，并可将其生存为图标(ico)、位图(bmp)两种方法。步调运转后界面如次：在上头的例程中，我调整出一个图标类cicons和与之相称的一个位图类cdib，个中囊括icons.h、icons.cpp、dib.h和dib.cpp四个文献。在你的工程市直接介入这四个文献后，挪用其类涵数，既可做出你本人的图标东西来。底下让咱们来看看怎样来简直用它们来实行：1、索取并表露出图标到左侧列表框中。代码实行如次：//读取百般资源里面图标并表露在左侧列表框中void ciconsnapdlg::onok() {    cfiledialog filedialog( true,"*.ico",null,null,"资源文献(*.ico,*.bmp,*.exe,*.dll,*.icl)|*.ico;*.bmp;*.exe;*.dll;*.icl||");if (filedialog.domodal() == idok) {            szopenfilename=filedialog.getpathname();            szopenfileextname= filedialog.getfileext ();     szopenfileextname.makelower ();     m_list.resetcontent (); //选清空左侧图标列表框     //读取并表露icon文献        if(szopenfileextname =="ico")      {         lpir=picons->readiconfromicofile (szopenfilename);               hicon hicon;         hicon=extracticon(afxgetinstancehandle(),szopenfilename,0);            if(hicon!=null)             m_list.addstring (szopenfilename);         cstatic* pstatic = (cstatic*) getdlgitem(idc_icons);        pstatic->seticon (hicon);     }     else if(szopenfileextname == "bmp") //读取并表露bmp文献     {            picons->iconimagefrombmpfile (szopenfilename,&lpir->iconimages[0],true);         hicon hicon;         hicon=picons->makeiconfromresource (&lpir->iconimages [0]);         if(hicon!=null)              m_list.addstring (szopenfilename);            cstatic* pstatic = (cstatic*) getdlgitem(idc_icons);        pstatic->seticon (hicon);     }        else //读取并表露exe、dll等资源文献     {        hinstance  hlibrary;        // load the dll/exe - note: must be a 32bit exe/dll for this to work        if( (hlibrary = loadlibraryex( szopenfilename, null, load_library_as_datafile )) == null )        {         // failed to load - abort         messagebox( szopenfilename+ "文献载入缺点，必需是win32的文献!", "缺点", mb_ok );         return;        }        // store the info        edii.szfilename =szopenfilename;        edii.hinstance = hlibrary;            // fill in the listbox with the icons available        if( ! enumresourcenames( edii.hinstance, rt_group_icon, (enumresnameproc )myenumprocedure, (lparam)getsafehwnd()) )        {         messagebox( "陈列图标资源名时堕落!", "缺点", mb_ok );         return;        }     }     m_list.setcursel (0);     if( m_list.getcount()  == 0 )     {         messagebox( "此文献中没有图标资源!", "缺点", mb_ok );         //无图标资源，置生存和复制按钮为失效状况         m_copy.enablewindow (false);         m_saveas.enablewindow (false);         return;     }        //有图标资源，置生存和复制按钮为灵验状况     m_copy.enablewindow (true);     m_saveas.enablewindow (true);     //革新挪用onpaint来表露图标     invalidaterect(null,true);}   }在onpaint()涵数中介入底下代码用来简直表露索取出的图标或位图资源。//按照左侧图标列表，运用onpaint()来革新右侧相映图标lptstr lpiconid;hicon hicon;if((lpiconid=(lptstr)m_list.getitemdata(m_list.getcursel()))!=(lptstr)lb_err ){ if(szopenfileextname=="exe"||szopenfileextname=="dll"||szopenfileextname=="icl") {       hicon=picons->geticonfrominstance(edii.hinstance,lpiconid);   cstatic* pstatic = (cstatic*) getdlgitem(idc_icons);   pstatic->seticon (hicon); }}2、怎样将索取出的图标资源生存为ico或bmp方法。//生存图标资源为ico或bmp方法文献void ciconsnapdlg::onbuttonsaveas() {    lptstr lpiconid;    cfiledialog filedialog( false,"*.ico",null,null,"图标文献(*.ico)|*.ico|位图文献(*.bmp)|*.bmp||");    if (filedialog.domodal() == idok)     {        szsavefilename=filedialog.getpathname();            szsavefileextname= filedialog.getfileext ();        szsavefileextname.makelower ();        if(szopenfileextname=="exe"||szopenfileextname=="dll"||szopenfileextname=="icl")           if((lpiconid=(lptstr)m_list.getitemdata (m_list.getcursel()))!= (lptstr)lb_err)                lpir=picons->readiconfromexefile (szopenfilename,lpiconid);        if(szsavefileextname=="bmp")        {          if(lpir!=null && m_list.getcount ()>0)          {            beginwaitcursor();            picons->iconimagetobmpfile (szsavefilename,&lpir->iconimages [0]);            endwaitcursor();          }          else            messagebox( "没有可生存的图标资源!", "缺点", mb_ok );        }        else if(szsavefileextname=="ico")        {          if(lpir!=null && m_list.getcount ()>0)          {            beginwaitcursor();            picons->writeicontoicofile (lpir,szsavefilename);            endwaitcursor();          }          else            messagebox( "没有可生存的图标资源!", "缺点", mb_ok );        }    }}之上代码的精细实行，请鄙人载后源码后，提防参看既可。接洽办法：地方：陕西省西安市处事路2号院六单位邮政编码：710082作家email：jingzhou_xu@163.net将来处事室(future studio)
