The CacheLimitInMegs property gets or sets the disk size allocated to the cache.

C++

HRESULT put_CacheLimitInMegs(
    long lLimit
);
HRESULT get_CacheLimitInMegs(
    long* plLimit
);

Parameters

lLimit
A 32-bit integer that specifies the disk size allocated to the cache, in megabytes.
plLimit
Pointer to a variable that on return receives a 32-bit integer that specifies the disk size allocated to the cache, in megabytes.

Return Value

Visual Basic

Property CacheLimitInMegs As Long

Property Value

A 32-bit integer that specifies the disk size allocated to the cache, in megabytes.

Remarks

This property is read/write. Its default value is 0.

Setting this property to a nonzero value for any drive automatically enables the cache. To disable the cache, the CacheLimitInMegs property must be set to 0 for all drives.

After you change the cache allocation, the change must be written to persistent storage by calling the Save method on the FPCCacheDrives collection or on an object that contains this collection as a subobject, and the Microsoft Firewall service must be restarted for the change to take effect. For more information about restarting the Firewall service to apply changes, see Restarting Services After Configuration Changes.
