PSPropertyBag_ReadLONG function

Reads a LONG data value from a property in a property bag.

Syntax


HRESULT PSPropertyBag_ReadLONG(
  _In_  IPropertyBag *propBag,
  _In_  LPCWSTR      propName,
  _Out_ LONG         *value
);

Parameters

propBag [in]

Type: IPropertyBag*

A pointer to an IPropertyBag object that represents the property bag in which the property is stored.

propName [in]

Type: LPCWSTR

A null-terminated property name string.

value [out]

Type: LONG*

When this function returns, contains a pointer to a LONG property value.

Return value

Type: HRESULT

If this function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

If the property bag does not already contain the specified property, the call still succeeds.

The property bag property function API converts between window types and the VARIANT type that is used to express values in a property bag. Doing so eases property bag usage, simplifies applications, and avoids common coding errors.
