The default web browser is used for .html, text viewer for .txt, etc. Starting folder workdir and command line cmdline parameters are optional.  C/C++ source code int gsShell( gsVM* vm ) { guard(gsShell) if(!gs_ckparamsmin(vm,1)) GS_RETURNINT(vm,0); if(!gs_cktype(vm,0,GS_STR)) GS_RETURNINT(vm,0); char* app = gs_tostr(vm,0); char* dir = NULL; char* cmd = NULL; if(gs_params(vm)>=2 && gs_cktype(vm,1,GS_STR)) dir = gs_tostr(vm,1); if(gs_params(vm)>=3 && gs_cktype(vm,2,GS_STR)) cmd = gs_tostr(vm,2); BOOL ret = (intptr)ShellExecute(NULL, "open", app, cmd, dir, SW_SHOW) > 32; gs_pushint(vm,ret); return 1; unguard() } gs_launch ( lib: Win, file: gslib_win.cpp ) int gs_launch( exefile, workdir, cmdline ) IN str exefile path to an executable file str workdir start directory (optional) str cmdline command line parameters (optional) OUT int 1=success, 0=fail Launch an executable (.exe) file. Starting folder workdir and command line cmdline parameters are optional.  C/C++ source code int gsLaunch( gsVM* vm ) { guard(gsLaunch) if(!gs_ckparamsmin(vm,1)) GS_RETURNINT(vm,0); if(!gs_cktype(vm,0,GS_STR)) GS_RETURNINT(vm,0); char* app = gs_tostr(vm,0); char* dir = NULL; char* cmd = NULL; if(gs_params(vm)>=2 && gs_cktype(vm,1,GS_STR)) dir = gs_tostr(vm,1); if(gs_params(vm)>=3 && gs_cktype(vm,2,GS_STR)) cmd = gs_tostr(vm,2); PROCESS_INFORMATION pi; STARTUPINFO si; memset(&si,0,sizeof(si)); si.cb = sizeof(si); BOOL ret = CreateProcess( app, cmd, NULL, NULL, FALSE, 0, NULL, dir, &si, &pi ); gs_pushint(vm,ret); return 1; unguard() } gs_commandline ( lib: Win, file: gslib_win.cpp ) str gs_commandline( ) OUT str command line Returns the command line the console or the embedding application was launched with. The command line will begin with the executable file's name that may use quotes. The GS9 console command line will continue with the name of the program file, since that is the first parameter.  C/C++ source code int gsCommandLine( gsVM* vm ) { guard(gsCommandLine); char* cmd = GetCommandLine(); gs_pushstr(vm,cmd); return 1; unguard(); } gs_messagebox ( lib: Win, file: gslib_win.cpp ) int gs_messagebox( text, title, type=MB_OK ) IN str text some text message str title box title (optional) int type=MB_OK buttons and icon flags (optional) OUT int selected button id Pops an Windows message box with the specified parameters. The type can be a binary combination of button and icon options. MB_OK, MB_OKCANCEL, MB_YESNO, MB_YESNOCANCEL, MB_RETRYCANCEL, MB_ABORTRETRYIGNORE for specifying the box's buttons. MB_ICONEXCLAMATION, MB_ICONQUESTION, MB_ICONERROR for specifying the box's icon MB_SYSTEMMODAL for blocking other applications until this box is closed It returns a response generating by chooseing one of the box's buttons. IDOK, IDCANCEL, IDYES, IDNO, IDABORT, IDRETRY, IDIGNORE func main() { gs_messagebox("This is a message","Info",MB_OK|MB_ICONEXCLAMATION); ret = gs_messagebox("Do you...?","Question",MB_YESNO|MB_ICONQUESTION); println((ret==IDYES)?"yes":"no"); }  C/C++ source code int gsMessageBox( gsVM* vm ) { guard(gsMessageBox) if(!gs_ckparamsmin(vm,1)) GS_RETURNINT(vm,0); if(!gs_cktype(vm,0,GS_STR)) GS_RETURNINT(vm,0); char* text = gs_tostr(vm,0); char* title = NULL; int type = MB_OK; if(gs_params(vm)>=2 && gs_cktype(vm,1,GS_STR)) title = gs_tostr(vm,1); if(gs_params(vm)>=3 && gs_cktype(vm,2,GS_INT)) type = gs_toint(vm,2); int ret = MessageBox(NULL,text,title,type); gs_pushint(vm,ret); return 1; unguard() } gs_messagebeep ( lib: Win, file: gslib_win.cpp ) int gs_messagebeep( type=-1 ) IN int type=-1 sound (optional) OUT int 1=success, 0=fail Generate an Windows message beep with the specidied parameters. The type can be one of the following: MB_ICONEXCLAMATION, MB_ICONQUESTION, MB_ICONERROR for specifying the box's icon. gs_messagebeep(MB_ICONEXCLAMATION);  C/C++ source code int gsMessageBeep( gsVM* vm ) { guard(gsMessageBeep) dword type = 0xFFFFFFFF; // default if(gs_params(vm)==1 && gs_cktype(vm,0,GS_INT)) type = gs_toint(vm,1); int ret = MessageBeep(type); gs_pushint(vm,ret); return 1; unguard() } MB_OK ( lib: Win, file: gslib_win.cpp ) MB_OK Used by gs_messagebox to specify dialog buttons.
