Big hex numbers negative?
by Fabian Cenedese Feb. 24, 2004

Feb. 24, 2004

Hi While testing more variant functions I tried this on Windows: double dVal; OLECHAR test1[]={'&', 'H', '8', '0', '0', '0', '0', '0', '0', '0', '\0'}; ok=VarR8FromStr(test1, LANG_NEUTRAL, NUMPRS_STD, &dVal); The result for dVal was -2147483648. But as a real value it shouldn't have any problems holding the "real" value 2147483648. So why has it become negative? Is it because the source form was a hex number? Are all hex numbers automatically signed if converted to int/real? Or just because of the 32nd bit? The documentation wasn't that informative. (The funny thing though was this remark in my VC6 help, it's not in the online version of MSDN anymore: Passing into this function any invalid and, under some circumstances, NULL pointers will result in unexpected termination of the application. For more information about handling exceptions, see Programming Considerations. ...now I understand many things :) Thanks bye Fabi

how to connect to com object "outside" from wine?
by maman yonatan Feb. 23, 2004

Feb. 23, 2004

Hi (I'm new in that group and don't know much about wine, so I'm sorry in advance if my question is in-proper) Here is my problem: I wrote in windows com object, and registered it in wine using regsv32 utility. I also wrote a com client application. When I executed the client code using Wine, all was just OK, and the client successfully make a reference to the server and activated It. :-) my question is there any way to write a client on the native (Linux) using g++ and activation the com object? does it make a difference if the com object id a dll, exe, or ocx ? 10x Yonatan __________________________________ Do you Yahoo!?

Re: crosstest compile fix (another)

We would come a long way >> if testers instead could install the Windows service (not yet written) >> that downloads >> the latest crosstest EXE from winehq and runs it. Speaking of which, SourceForge seems like the ideal way to build nightly Winetests by using their compile farm. I've been trying to get access to it for a few days in order to figure that out. All of the pieces seem to fit together and the only unknown is whether or not they have mingw on their servers. Does anyone else have any suggestions how we could create nightly builds? -brian

"oleaut32"="builtin" crash on OCX hosting with ATL
by Boaz Harrosh Feb. 23, 2004

Feb. 23, 2004

Hi Marcus Do you need a little(est) test with full source code that hosts an OCX (The OCX is IE but I can change it if you need). It is written with ATL/WTL. It will work fine with: "oleaut32"="native" but will crash with "oleaut32"="builtin". I also have a winelib that crashes the same (same code), but contact me personally if you need the source for that. (I could post the .exe.so with full debug info) I would give it a shut, but it will only be months from now. It didn't look very simple, but maybe I am wrong about that. Free Life Boaz

Some compatibility issue with InternetCrackUrlA
by wire99＠21cn.com Feb. 23, 2004

Feb. 23, 2004

Hi all. I've tried some applications with wine, and discovered the different behavior compare to the real winapi. 1. If there is no explicit port number in the URL, the value of lpUC->nPort will be assigned to zero in wine, but in winapi it should be the default port number of the corresponding scheme. 2. Before call InternetCrackUrlA, if the field dwExtraInfoLength of lpUrlComponents set to 0, the ExtraInfo of the URL is not parsed at all; only the dwExtraInfoLength is set to non-zero, ExtraInfo would be filled. But Wine would always do parse. (I just find it has been reported at http://bugs.winehq.com/show_bug.cgi?id=1805) Below is a rough patch for this issue, some download manager apps (ie. flashget) affected work now.

Honestly though, before the Euro, prices in supermarkets were in cents and added up to the cent but the total amount was rounded up to the next 5 cents.

Re: imagelist: convert to dibsections
by Vitaliy Margolen Feb. 23, 2004

Feb. 23, 2004

This patch brakes a lot of images/icons etc. Needs more testing. In particular small icons in all browser panes. Also we still have some problems with our DIBs, Which could be easily seen with native comctl32. So I'm not sure if we should use DIBs in imagelist yet.

Hi, >VT_R4: 7.850 -> VarRound(1) -> 7.800 >VT_R4: 7.851 -> VarRound(1) -> 7.900 >Is this the binary representation (in)accuracy? MS state that rounding is dependent on the internal binary representation of the number and thus VarRound doesn't always get it right, i.e. you can't tell with any certainty what the result will be. You have 2 choices: try and match their exact algorithm (v. hard w/o reverse engineering) or use the dutch rounding method (this makes more sense IMO). >How can I test if the rounding worked ok when the numbers may > differ in the last (invisible) bits? As long as Wine does the right thing don't worry about it. > And how should I round a currency? It's valid on Windows but I > couldn't interpret the results. > Is this some kind of fixed comma type? The currency value is multiplied by 10000 and stored in an I8 (See the VarCy* functions). So it has 4 dp of precision. To round to: 4 dp or more => no op. 0 dp => / 10000, then * 10000 1 dp => / 1000, then * 1000 2 dp => / 100, then * 100 3 dp => / 10, then * 10 mults and divs should be done on the I8 directly (no float).

DLL, shared library, ...
by Robert Vojta Feb. 23, 2004

Feb. 23, 2004

Hallo all, I would like to ask you if there is a way how to convert .dll library to the Linux .so library? This library contains simple functions (something like voice codec) "without any dependency" on the Windows operating system - it's "platform independet", but packed into the .dll. I'm trying google, wine mailing list archives and I can't find anything about this issue. Do you think it's possible to do this or should I forgot and fight for the source code? Best regards, Robert -- Robert Vojta

+relay stops window output?
by Fabian Cenedese Feb. 23, 2004

Feb. 23, 2004

Hi I have a problem with debugging. Since cvs update today I can't use +relay anymore. The app window comes up but doesn't show any content. It's just an empty frame with dead visuals and doesn't react. I can drag the frame and close it. But it works ok if I e.g. have +ole. Same is with other apps which worked last week. Is this a known problem? Thanks bye Fabi
