From: Sherwood Hu on 30 Nov 2009 12:53 I need to add scripting capabilities to an existing application. I read some docuentation about Active Scripting and wrote a small application to execute VBScript code. The program seems working fine with simple code such as i=10. However, When I try to call MsgBox function, it returned an error message that permission is declined. I noticed that MsgBox can't be used in classic ASP. However, my case is a desktop application. Is there something I can do to enabel MsgBox function on scripting. Or Microsoft has put some restrictions on VBScript code executed from custom programs. I am running on Vista.

I am running on Vista. It should work. I have no problem with popup boxes using local scripts (.VBS) or client side browser scripts. What do you mean by "existing application?"

The code (written in C++) looks like this: ScriptEngine* se = new ScriptEngine(); bool rc = se->Initialize(); assert(rc==true); // const wchar_t code[] = L"MsgBox \"this is good.\", 0 "; const wchar_t code[] = L" " L"Dim fso, MyFile\r\n" L"Set fso = CreateObject(\"Scripting.FileSystemObject\")\r\n" L"Set MyFile = fso.CreateTextFile(\"c:\\testfile.txt\", True)\r\n" L"MyFile.WriteLine(\"This is a test.\")\r\n" L"MyFile.Close\r\n"; rc = se->Execute(code); Note that a lot of code is inside ScriptEngine class (which implements IActiveScriptSite interface and connects to VBScript engine). The second script worked just fine - a file was created under c:\ successfully. The first script returned an error. Inside IActiveScriptSite::OnScriptError it reports: "Script error detected at line 0. Description: Permission denied: 'MsgBox'" |
