VariantTimeToSystemTime

[GregL]

In oleaut32.inc

VariantTimeToSystemTime PROTO :DWORD,:DWORD,:DWORD

should be

VariantTimeToSystemTime PROTO :DWORD,:DWORD

Greg,

The actual decorated name is "_VariantTimeToSystemTime@12" so if the arguments are DWORD sized, 3 parameters are correct. I took this from the oleaut32 library for XP. The older ones are the same.

Hutch,

You are absolutely right. My mistake. It does take 12 bytes. One of the args is a double.

INT VariantTimeToSystemTime(
  double  vtime,             
  LPSYSTEMTIME  lpSystemTime 
);


I was getting an error from POASM about the arguments. I quickly looked at MSDN, saw two args and didn't notice the double.

POASM's INVOKE  doesn't like

Code Select Expand

VariantTimeToSystemTime PROTO :DWORD,:DWORD,:DWORD
it also doen't like

Code Select Expand

VariantTimeToSystemTime PROTO :REAL8,:DWORD
nor

Code Select Expand

VariantTimeToSystemTime PROTO :QWORD,:DWORD

but it did accept

Code Select Expand

VariantTimeToSystemTime PROTO :DWORD,:DWORD which is wrong.

Thanks for pointing that out. When using POASM, I need to keep in mind that I'm using a newly released assembler. I'm also unable to assemble most of the FPU instructions with POASM. I posted it on Pelle's Forum.

Hutch,

I tried assembling the same VariantTimeToSystem code with MASM. MASM's INVOKE doesn't like

Code Select Expand


VariantTimeToSystemTime PROTO :DWORD,:DWORD,:DWORD
either.

Changing the PROTO to

Code Select Expand

VariantTimeToSystemTime PROTO :REAL8,:DWORD
or

Code Select Expand

VariantTimeToSystemTime PROTO :QWORD,:DWORD fixed the problem.

I'm using it like this

invoke VariantTimeToSystemTime, varDate1, ADDR MyST1
