I work with installshield 2008 and my project is a basic msi project
I have write a fonction test who just return a value
function string ReturnTest(hMSI)
begin
return "hello"; end;
that works if i use this function i can have the result in a messagebox but now
i would like to place this return value in the others function as this for example ;
function ResultTest(STRING)
begin //Use the string HERE end;
but when i compile the code that doesn't work at all ! C:\InstallShield 2008 Projects\SQLCONNECT_Insert\script files\setup.rul(84) : error C8003: 'ResultTest' : function has no prototype declaration C:\InstallShield 2008 Projects\SQLCONNECT_Insert\script files\setup.rul(84) : error C8008: 'STRING' : identifier expected Is it possible to pass some parameters in a function ?
Please see the help topic "Prototyping Functions"; in general, a new function needs two pieces, as in:
prototype int FunctionName(STRING, NUMBER);
function FunctionName(szSomething, nSomethingElse) STRING temp; begin
// do something
return 0; end;
If you want to define an InstallScript custom action function, though, please see "Writing Entry-Point Functions". The prototype must be:
export prototype ActionName(HWND);
and the function body:
function ActionName(hInstall) begin
// do something
return ERROR_SUCCESS; end;
To pass additional information back and forth between the installer and your InstallScript function, you'll need to use MsiGetProperty and MsiSetProperty.
