Passing the low and high words separately as specified by the documentation? You can't just pass a LARGE_INTEGER or LARGE_INTEGER pointer.

Have you actually checked what the value is that you're passing to it? It's entirely possible that SetFilePointer isn't lying and that you are passing a negative number to it?

Calling C#dll via C++ from Java

Hai

I've been under a great prob.. since 2 days...

Issue is :
I've built a C#dll which is accessed from VC++(win32 console dll app)..
I've created a Java program to access the dll of the said C++ program...
I was successful in getting it worked ...
Problem comes when I run the same application in a different system where all the
needed visual studio files are installed...

From java i can access the C++ dll but the error comes in accessing C# dll(through the C++ program)...

NB: error accurs only when it is run on a different machine...
Error is:

# An unexpected error has been detected by HotSpot Virtual Machine:
#
# Internal Error (0xe06d7363), pid=4024, tid=4028
#
# Java VM: Java HotSpot(TM) Client VM (1.5.0_09-b01 mixed mode, sharing)
# Problematic frame:
# C [kernel32.dll+0x1eb33]
#
# An error report file with more information is saved as hs_err_pid4024.log
#
# If you would like to submit a bug report, please visit:
# http://java.sun.com/webapps/bugreport/crash.jsp

i've done "googling" with this error... but no one has come up with some satisfactory answer...
Pls do help.....

Thanks in advance ...

Thanks for ur reply

I dnt think the problem is with the installation of .net framework..

coz... same application works fine when the C++ project is complied/build
there..

I'll suggest you get busy with the debugger Smile | :)

If the target machine hasn't got Visual Studfio, then use WinDbg[^]. Debug java.exe, specifying the entrypoint class on the command-line as you would normally and run the Java app. When the exception occurs (looks like it's in kernel32 during a call to the C run-time) the debugger should give you better information about where it's happened.

The debugger will warn you that Java.exe has no debug information, but that doesn't matter.

This approach does work for debugging native+Java hybrids - I used it myself last week to debug my very first app using JNI Smile | :)

inverse function of SystemTimeToTzSpecificLocalTime() - OS = Win2K

includeh1022-Jun-09 20:43

22-Jun-09 20:43

MSDN says:

//-----------------------------------
SystemTimeToTzSpecificLocalTime
The SystemTimeToTzSpecificLocalTime function converts a Coordinated Universal Time (UTC) to a specified time zone's corresponding local time.
//-----------------------------------

Now I need an inverse function of above, which can convert local time to UTC time.

Is there a function to do that?

Re: inverse function of SystemTimeToTzSpecificLocalTime()

Stuart Dootson22-Jun-09 22:25

Stuart Dootson

22-Jun-09 22:25

Well - all TzSpecificLocalTimeToSystemTime is going to do is offset the time by the time offset implied by the timezone you pass into it. So, you just need to do the same.

If you would be passing a null time-zone into that function, then you can do what it does and retrieve the current time zone information using GetTimeZoneInformation[^]. That gives you the current time-zone information, including the biases to be applied to UTC to get local time (or vice versa!). So, all you have to do is work out how to add the suitable number of minutes to your local timke - I'd probably convert the SYSTEMTIME to a FILETIME, do the time biassing and then convert the FILETIME back to a SYSTEMTIME.
