How to manually define feature size?

[Server]

I have some empty features in the project because they are used in Billboard/Support Files. They reported as 0kb ones during installation. Actually, they take some space on the HDD. How to force feature size to appear or define them manually?

What type of project are you using? For InstallScript, you should be able to call FeatureAddCost; and for MSI, you can add data to the ReserveCost table.

I use this method (but it is InstallShield 11.5) and feature's size still zero (actually, no files included in it, but I need non zero cost):

//---------------------------------------------------------------------------
// OnBegin
//
// The OnBegin event is called directly by the framework after the setup
// initializes. Note that this event will be called AFTER "Initialization"
// events (i.e.) OnSetTARGETDIR, OnCheckMediaPassword.
//
// Note: This event will not be called automatically in a
// program...endprogram style setup.
//---------------------------------------------------------------------------
function OnBegin()
number nCostHigh, nCostLow;
begin
CalculateAndAddFileCost( 0, 250 * 1024 * 1024, TARGETDIR, 0, nCostHigh, nCostLow );
FeatureAddCost( MEDIA, "DefaultFeature", TARGETDIR, nCostHigh, nCostLow );
end;

A quick example with that same code works for me (in InstallShield 2008); which feature dialog box are you using?

Hi,
if I use the description below, to set the size of my features this will work fine.
But if the calculated size of the selected features is greater than the disk space ->the user selects another drive and now the size is calculated again.
The problem is in first calculation FeatureA (2.0MB) and on calculation again (+ 2.0MB) (2nd 4.0MB, 3rd 6.0MB and so on...)
How can i specify the size of my features not calculate again if there is a new drive selected?

Thanks
