The zero-based line number for the start of the function.nLineEnd
The zero-based line number for the end of the function.
Return Value
A string containing the code for initializing the wizard instance.
Remarks
Call this member function to retrieve the appropriate code for initializing the wizard instance. The line numbers are as follows:
Line number |
InitInstance Code |
|---|---|
0 |
CWinApp::InitInstance(); |
1 |
return TRUE; |
2 |
AfxOleInit(); |
3 |
// Parse command line for standard shell commands, DDE, file open |
4 |
CCommandLineInfo cmdInfo; |
5 |
ParseCommandLine(cmdInfo); |
6 |
// App was launched with /Embedding or /Automation switch. |
7 |
// Run app as automation server. |
8 |
if (cmdInfo.m_bRunEmbedded || cmdInfo.m_bRunAutomated) |
9 |
{ |
10 |
\t// Register class factories via CoRegisterClassObject(). |
11 |
\tif (FAILED(_AtlModule.RegisterClassObjects(CLSCTX_LOCAL_SERVER, REGCLS_MULTIPLEUSE))) |
12 |
\t\treturn FALSE; |
13 |
\t// Don't show the main window |
14 |
\treturn TRUE; |
15 |
} |
16 |
// App was launched with /Unregserver or /Unregister switch. |
17 |
if (cmdInfo.m_nShellCommand == CCommandLineInfo::AppUnregister) |
18 |
{ |
19 |
\t_AtlModule.UpdateRegistryAppId(FALSE); |
20 |
\t_AtlModule.UnregisterServer(TRUE); |
21 |
\treturn FALSE; |
22 |
} |
23 |
// App was launched with /Register or /Regserver switch. |
24 |
if (cmdInfo.m_nShellCommand == CCommandLineInfo::AppRegister) |
25 |
{ |
26 |
\t_AtlModule.UpdateRegistryAppId(TRUE); |
27 |
\t_AtlModule.RegisterServer(TRUE); |
28 |
\treturn FALSE; |
29 |
} |
For each of the lines returned, GetCodeForInitInstance adds a leading tab (\t) and a trailing "CR-LF" (carriage return - linefeed) character pair (\r\n).
Example
// Get the lines numbered 0 through 2 above
GetCodeForInitInstance(0, 2)
// returns the following string
// "\tCWinApp::InitInstance();\r\n\treturn TRUE;\r\n\tAfxOleInit();\r\n"
