I. Preface

Many software works are added to the [help] menu to [access our homepage...]. Look at some of its implementation methods, and I think it is too complicated. During the design of "Xiaohui desktop Wang-jiujing method photo album series", Xiaohui successfully implemented [Access to Xiaohui's homepage...] in the program. (The fourth button in the right figure), the code segment is very simple, and now the setting idea and implementation code are attached. Xiaohui desktop Wang-jiujing method photo album is a small tool written by Xiaohui. Interested readers can download the source code (498kb) from here ).

Ii. Design Ideas

Xiao Hui's implementation method is: first, obtain the path name of the Windows default browser by reading the Registry, and then execute the default browser with parameters. The parameters included are the Homepage Address to be called. -- To put it bluntly, it is actually very simple. The default key value of the windows browser is 'HKEY _ classes_root/htmlfile/Shell/Open/command' in the registry '. The implementation code is as follows:

Void cxh1_dlg: onbtnweb () { Hkey hkroot, hsubkey; // defines the root keyword and subkeyword of the Registry. Char valuename [256]; Unsigned char datavalue [256]; Unsigned long cbvaluename = 256; Unsigned long cbdatavalue = 256; Char shellchar [256]; // defines the command line DWORD dwtype; // Open the Registry root keyword If (regopenkey (hkey_classes_root, null, & hkroot) = error_success) { // Open the subkeyword If (regopenkeyex (hkroot, "Htmlfile // shell // open // command ", 0, Key_all_access, & Hsubkey) = error_success) { // Read the registry and obtain the command line of the default browser Regenumvalue (hsubkey, 0, Valuename, & Cbvaluename, Null, & Dwtype, Datavalue, & Cbdatavalue ); // Call parameter (Home Address) Assignment Strcpy (shellchar, (char *) datavalue ); Strcat (shellchar, "www.neaase.net /~ Xiaohui "); // Start the browser Winexec (shellchar, sw_show ); } Else MessageBox ("An error occurred while opening the web browser! "," Error ", mb_ OK ); } Else MessageBox ("An error occurred while opening the web browser! "," Error ", mb_ OK ); // Close the registry Regclosekey (hsubkey ); Regclosekey (hkroot ); }
