Available and required drive space

[m_stretavsky]

I have a problem with display available and required space in Dlg_SdFeatureTree. I tried set szDir param which specifies the path that is used in calculating required and available drive space to variable TARGETDIR and INSTALLDIR but dialog still display available space and required space value 0. Can any help me? Thanks

Can you post a code block where you call SdFeatureTree?

    szTitle = "";
    szMsg = "";
    szFeatures = "";
    nLevel = 2;
nResult = SdFeatureTree( szTitle, szMsg, TARGETDIR, szFeatures, nLevel );

This should work. I am assuming you are working with a pure InstallScript setup here though.

Dlg_SdFeatureTree: 
   if ((nResult = BACK) && (nSetupType != CUSTOM)) goto Dlg_SetupType;
                szTitle    = "";
                szMsg      = "";
                szTargetdir = TARGETDIR;
                szFeatures = "";
                nLevel = 2;
                if (nSetupType = CUSTOM) then
                 	nResult = SdFeatureTree(szTitle, szMsg, szTargetdir, szFeatures, nLevel); .....

it's my code. Project was created in older version InstallShield but I don't know which version. I don't understand how it's possible 😞 . Thanks for help

Have you stepped through the debugger to verify that TARGETDIR has a valid directory? That is the only reason I can see is that TARGETDIR is not being set correctly prior to this call.

so, TARGETDIR variable have same value like a INSTALLDIR variable - C:\Program Files\My Company Name\My Company product. I tried set to szDir param value like "C:\\" or "D:\\" but with same result.
