网上貌似没有VB数组调试相关的内容
我也是参看搜索的一些信息自己慢慢研究出来的
没地方发就发这好了
首先VB的类型都是作为Variant来表达，想在OD下了解Variant的具体含义就得先弄懂Variant的结构
下面是Variant的完整结构:
typedef [wire_marshal(wireVARIANT)] struct tagVARIANT VARIANT;
struct tagVARIANT {
union {
struct __tagVARIANT {
VARTYPE vt;
WORD wReserved1;
WORD wReserved2;
WORD wReserved3;
union {
LONG lVal; /* VT_I4 */
BYTE bVal; /* VT_UI1 */
SHORT iVal; /* VT_I2 */
FLOAT fltVal; /* VT_R4 */
DOUBLE dblVal; /* VT_R8 */
VARIANT_BOOL boolVal; /* VT_BOOL */
_VARIANT_BOOL bool; /* (obsolete) */
SCODE scode; /* VT_ERROR */
CY cyVal; /* VT_CY */
DATE date; /* VT_DATE */
BSTR bstrVal; /* VT_BSTR */
IUnknown * punkVal; /* VT_UNKNOWN */
IDispatch * pdispVal; /* VT_DISPATCH */
SAFEARRAY * parray; /* VT_ARRAY 安全数组类型*/
BYTE * pbVal; /* VT_BYREF|VT_UI1 */
SHORT * piVal; /* VT_BYREF|VT_I2 */
LONG * plVal; /* VT_BYREF|VT_I4 */
FLOAT * pfltVal; /* VT_BYREF|VT_R4 */
DOUBLE * pdblVal; /* VT_BYREF|VT_R8 */
VARIANT_BOOL *pboolVal; /* VT_BYREF|VT_BOOL */
_VARIANT_BOOL *pbool; /* (obsolete) */
SCODE * pscode; /* VT_BYREF|VT_ERROR */
CY * pcyVal; /* VT_BYREF|VT_CY */
DATE * pdate; /* VT_BYREF|VT_DATE */
BSTR * pbstrVal; /* VT_BYREF|VT_BSTR */
IUnknown ** ppunkVal; /* VT_BYREF|VT_UNKNOWN */
IDispatch ** ppdispVal; /* VT_BYREF|VT_DISPATCH */
SAFEARRAY ** pparray; /* VT_BYREF|VT_ARRAY */
VARIANT * pvarVal; /* VT_BYREF|VT_VARIANT */
PVOID byref; /* Generic ByRef */
CHAR cVal; /* VT_I1 */
USHORT uiVal; /* VT_UI2 */
ULONG ulVal; /* VT_UI4 */
INT intVal; /* VT_INT */
UINT uintVal; /* VT_UINT */
DECIMAL * pdecVal; /* VT_BYREF|VT_DECIMAL */
CHAR * pcVal; /* VT_BYREF|VT_I1 */
USHORT * puiVal; /* VT_BYREF|VT_UI2 */
ULONG * pulVal; /* VT_BYREF|VT_UI4 */
INT * pintVal; /* VT_BYREF|VT_INT */
UINT * puintVal; /* VT_BYREF|VT_UINT */
struct __tagBRECORD {
PVOID pvRecord;
IRecordInfo * pRecInfo;
} __VARIANT_NAME_4; /* VT_RECORD */
} __VARIANT_NAME_3;
} __VARIANT_NAME_2;
DECIMAL decVal;
} __VARIANT_NAME_1;
};
第一个word是VARENUM常数下面列出VARENUM常数的结构和代表的含义
typedef unsigned short VARTYPE;
