Encryptor for SB

[NewsArchive]

Before re-inventing the wheel - has anyone got an encryptor dll add-on for
SetupBuilder?

I'm thinking, something like

ReturnValue = EncryptString(StringIn,EncCode,EncMethod)

Otherwise I'll knock up a dll...

Talking about knocking up a dll - I'm doing something dumb. I've got a dll -
#include it into the sb6 file, load it, call the dll function - but nothing
is returned and the stop that I'm calling in the function isn't being
displayed. Hmmm. Do I need the DLL to be in a special place (like in the lib
directory)? The sb script compiles OK - and I can see if finds the dll - but
runtime?

Friedrich - can you give me some troubleshooting pointers on this one?

Thanks

There are three or four interesting DLL example source codes in the Example
Projects Package:

Does this help?

Geoff,

Don't know if this will help, but I'm calling into Clarion and C DLLs with no
problem. Here's an example of a call into a Clarion DLL.

Given a prototype of:

GetLicenseStatus( *cstring szExePath, |
*cstring szDataPath, |
*cstring szProgVersion, |
*cstring szLicensee, |
*cstring szSupportExpires, |
long lProductCode, |
*long lUpdateOk, |
*long lLicenseType, |
*long lLicenseOptions |
), long, pascal

The SB call looks like... Well, have a look at the image.

May also be useful to note the DLL path of %TMPDIR%\utilfunc_install.dll

Geoff,

One other bit I forgot to mention. Add your DLL in Support Files in Setup
Requirements of the Visualizer. You can also do this directly in the script
editor using "#include support file".

At runtime (and testing) SB writes support files to the OS temp directory and
deletes it/them automatically. Thus the %TMPDIR%\utilfunc_install.dll
reference in that screen shot of mine.

HTH.

OK - got the DLL bit working - but can't seem to find a way of returning a
string. Ideally would like something like:

ENCRYPTFUNCTION FUNCTION(*CSTRING pInString,*CSTRING pHashCode)
code
!Encode stuff
return EncodedString

Seems like %_SB_RETURN% is a long and %_SB_RETURNEX% isn't set. So how do I
get a string back?

I tried modifying and returning pInString direct - but it seems like the
handle isn't passed - there's a handle declared at runtime and the contents
of pInString (in the install) - is passed to the internal/runtime var.

Did you check the "Call Dll.sb6" source code example project? In this demo
there is in line 51:

Call DLL "%TMPDIR%\sbdll.dll" -- Function "CALLTHISFUNCTION2" (*cstring)
(%LPBUFFER%)

The Clarion DLL sbdll.dll returns a CSTRING value to the installer.

Or in line 65:

Call DLL "kernel32.dll" -- Function "GetComputerName" (*string, *long)
(%LPBUFFER%,%NSIZE%)

The Windows API returns a STRING value to the installer.

Does this help?
