Hi all, Thanks to Wayne and Park, I''ve got something like this now: static VALUE file_set_compressed(VALUE self, VALUE rbBool){ HANDLE h; BOOL rv; DWORD dwBytesReturned; int fn; USHORT inBuf = COMPRESSION_FORMAT_DEFAULT; if((rbBool != Qtrue) && (rbBool != Qfalse)){ rb_raise(rb_eTypeError,"Argument must be true or false"); }

Hello, I have a usb data aquisition device interfaced by mass storage protocol. I open it like: hEcgDrive=CreateFile("\\\\.\\g:", GENERIC_READ | GENERIC_WRITE, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL | FILE_FLAG_NO_BUFFERING | FILE_FLAG_WRITE_THROUGH | FILE_FLAG_OVERLAPPED, NULL); for communication I use DeviceIoControl(hEcgDrive,

Hi all, I''ve got overlapped and offset support in both nread and nwrite. The only thing left before I want to release this (as 0.4.0) is to get NO_BUFFERING to work. Unfortunately, I can''t get it to work. Park, I looked at that site you sent (and borrowed some code from it), but I don''t see anything special happening for NO_BUFFERING. I thought it required

Hi all, I''ve checked in some code to win32-changenotify. Unfortunately, it doesn''t work right. I need some help. I don''t understand what, exactly, I''m supposed to pass to ReadDirectoryChangesW() for the 2nd argument, nor how to read the data back out. There''s also a WCHAR issue that needs to be worked out with regards to the FileName

Hi all, Windows 2000 Ruby 1.8.2 RC9 Is it possible to call File.open on a directory in Windows? I always get Errno::EACCES, even though there are no special settings on the directories I''ve tried and I have full access. Dan

This question isn't directly Samba related, but Samba has helped me figure out part of the problem. When I CreateFile on an existing file like so: CreateFile(FileName, GENERIC_READ, FILE_SHARE_READ | FILE_SHARE_DELETE, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL); Samba shows that I have the file opened with this type of lock DENY_NONE 0x20089 RDONLY When the file is locked in

This patch renames flac_internal_CreateFile_utf8() function to grabbag__CreateFile_utf8() and moves it from /src/libFLAC/windows_unicode_filenames.c into src/share/grabbag/file.c This function is not used by libFLAC anyway. After this, it should be possible to compile libFLAC as UWP. In the old code there were 3 different #if conditionals around the code that uses CreateFile_utf8(): 1) #ifdef

Hi all, > fh = File.nopen("C:\\temp.txt",File::WRITE_ATTRIBUTES) > fh.hidden = true > fh.close > > I get "test.rb:16:in `hidden='': cannot convert nil into > String (TypeError)" It looks like this line is the culprit: rbPath = rb_funcall(self,rb_intern("path"),0,0); Hm...we could use GetFullPathName() if rbPath is nil. That, however,

Hello, Today I ran into some frustration with spec and windows. We have a series of plugins that have either test suites and/or spec suites. To avoid environment collisions, we have a "master" test suite that spawns new process for all of the test suites and spec suites. Every works great on posix. Unfortunately on windows, spec was not found. The only way I figured to ensure we get

All, I got a bug report from Greg Holmes where the description wasn''t being returned properly. At the moment, if there''s no event associated with the event id, then the description is empty. However, it turns out that there can still be associated information about the event. So, I propose the following tweak to the get_description private method: # If FormatMessage()

Hi, I was going to modify the TaskScheduler#save method to take an optional file name. But, I need to convert a Ruby string to an OLE string. I thought I could use this: http://msdn.microsoft.com/en-us/library/ms692615(VS.85).aspx But, it only appears to accept literal string constants. Any other suggestions? Thanks, Dan

I''ve gotten a lot farther building wxRuby than I did a few months ago. But its getting late here and I''m going to bed. In the meantime, does anyone know why I''m getting this compile error: Microsoft (R) Program Maintenance Utility Version 6.00.8168.0 Copyright (C) Microsoft Corp 1988-1998.

Hi, I'm sure that this question has come up many times before. When I load an R extension dll I've built with the Microsoft compiler, I get the warning: Warning message: DLL attempted to change FPU control word from 8001f to 9001f So, what I did to try to fix the problem (to my knowledge, Microsoft will not support compile time switching of floating point control until version

I tried to download/compile/install win32-dir, but I couldn''t get it to go. Over a private email Daniel Berger had me... "Curious. What platform are you on exactly?

I know that the folks at Ruby Central (David Black, Chad Fowler, Rich Kilmer, et al) had a big impact on Ruby being added to Google''s ''Summer of Code''. They tried last year, but they made it happen this year. Based on that, I''ve made a donation to Ruby Central [1] to support the work that they do (as I did last year). I''d love to see my (almost a)

Hi all, I''ve added some critical section methods to the Windows::Synchronize module in the windows-pr library (in CVS). Looking at the RUBY_CRITICAL macro from rubysig.h, it basically looks like this (in pure Ruby): def RUBY_CRITICAL(&block) critical_section = [0].pack(''L'') InitializeCriticalSection(critical_section)
