Migrating from Win9x to Linux - PLEASE HELP! Sergei Yevseyev28-Dec-01 4:16 Sergei Yevseyev 28-Dec-01 4:16  Who knows, how to perform a migration from VC6 code to GNU C++ (from Slackware Linux 7.10 distribution) with minimum rewriting. Any ideas? My application is not a console one . and uses: 1. MFC Cdialog 2. Subclassed dialog amd buttons from BCGControlBar and other libs 3. DAO Thanks!

I don't know of any though Sergei Yevseyev wrote: Subclassed dialog amd buttons from BCGControlBar and other libs Doesn't sound promising. Contact the makers and see if there is a Linux port. Although if they are subclassed from MFC it doesn't sound promising. Sergei Yevseyev wrote: DAO I don't know anything about this but I would think there is a Linux alternative. I would suggest you start over in terms of GUI. - Matt Newman - Matt Newman -Sonork ID: 100.11179:BestSnowman Re: Migrating from Win9x to Linux - PLEASE HELP!

I suggest you use some OS-independent library like wxWindows. Anyway, why would you port your GUI application to Linux? Less then 5% of PC users run Linux on their desktop computers?

Unfortunately it's a bit expensive. // Fazlul Get RadVC today! Play RAD in VC++ http://www.capitolsoft.com Re: Migrating from Win9x to Linux - PLEASE HELP! Ravi Bhavnani28-Dec-01 5:31 Ravi Bhavnani 28-Dec-01 5:31  Sergei, we use Tcl/TK to build cross platform GUIs. All the non-GUI code is built as libraries (DLL/so) that are linked into Tcl. /ravi "There is always one more bug..." ravib@ravib.com http://www.ravib.com Re: Migrating from Win9x to Linux - PLEASE HELP! Tomasso7-Jan-02 7:10 Tomasso 7-Jan-02 7:10  What about wxWindows (http://www.wxwindows.org/)? It works on both Windows, Linux, MacOS, and several others, I'm sure. I've toyed around with it, and it works nicely. "If ye love wealth better than liberty, the tranquility of servitude better than the animating contest of freedom, go home from us in peace.

How can i access the recordset from that dialog. i have tried including the header, and defining the recordset external. i think i am just missing a step. thank you for any help on this. Re: access CRecordSet from another class Carlos Antollini28-Dec-01 3:05 Carlos Antollini 28-Dec-01 3:05  You need to open the recordset from a extarnal class to your dialogs, for example in the app class.... In this way the recordset can be open from any dialog and readed from any dialog.... Best Regards.... Carlos Antollini.

CTDSMSet* m_pSet; i have been able to move the class declaration to my app header but nothing else with out errors. do you know if there is any documentation on moveing everything to the app class from a view class? or am i just looking to hard at this configuration maybe? Re: access CRecordSet from another class Carlos Antollini28-Dec-01 5:07 Carlos Antollini 28-Dec-01 5:07  Always I prefer no use CRecordView, I prefer to declare de Database class and recordset in a public class for all classes in my application.... You need to see how can get access to the view from any dialog or other classes.... Try to get access to the View using AfxGetMainWnd(); Best Regards.... Happy new year!!! Carlos Antollini.

Shog928-Dec-01 8:58 Shog9 28-Dec-01 8:58  You can draw, provided you can get a DC; // ... CClientDC dc(this); // draw stuff // ... However, there's a good chance that the window is not visible yet, so drawing into it will not be very useful. A better idea is to use the class as it was intended; initialize any data necessary for drawing in OnInitialUpdate(), updated it in OnUpdate(), and draw it in OnDraw(). OnDraw() will be called when the window is shown and first needs to be updated, so if you place your drawing code there, the view will act as desired. i ain't happy, i'm feeling glad; i got sunshine in a bag; i'm useless, but not for long; the future is coming on... gorillaz, clint eastwood Re: how can i DRAW in CVIEW:OnInitialUpdate() function?

Nish Nishant27-Dec-01 21:56 Nish Nishant 27-Dec-01 21:56  Subject :- Isn't there native support for PNG in Windows? I've requoted my subject. Christian and other GDI gurus... This shocked me quite a bit. I checked out the bitmap section on CP. There are several classes available to display PNG files. But I thought I should start from scratch and try and show a PNG first before I try to manipulate it.

Mike Nordell27-Dec-01 23:02 Mike Nordell 27-Dec-01 23:02  Isn't there native support for PNG in Windows? Using Win32 API? No. You can probably work around this by fiddling with COM objects the Internet Explorer pollutes your system with, or you can use e.g. libpng [libpng.org] /Mike Re: Isn't there native support for PNG in Windows? Nish Nishant27-Dec-01 23:14 Nish Nishant 27-Dec-01 23:14  What's so special about PNG anyway? What's wrong with JPG,BMP,GIF??? Why do people want PNG all of a sudden? Nish Sonork ID 100.9786 voidmain www.busterboy.org If you don't find me on CP, I'll be at Bob's HungOut Re: Isn't there native support for PNG in Windows? Mike Nordell27-Dec-01 23:22 Mike Nordell 27-Dec-01 23:22  What's wrong with JPG,BMP,GIF??? JPG is complex and lossy. BMP is basically a raw bit-dump, and as such the most bloated format you could use for off-line storage. GIF is limited by evil patents. PNG has no patent issues, has lossless compression and is just free. Why do people want PNG all of a sudden? All of a sudden? Well, one of the reasons could be that it has been a W3C standard (or was that "just" a recommendation?) for quite a few years now. /Mike Re: Isn't there native support for PNG in Windows? Nish Nishant27-Dec-01 23:41 Nish Nishant 27-Dec-01 23:41  Thanks for all that info. The fact is right now I am in a sort of anti-PNG attitude for some personal-job-related reasons Nish Sonork ID 100.9786 voidmain www.busterboy.org If you don't find me on CP, I'll be at Bob's HungOut Re: Isn't there native support for PNG in Windows? markkuk27-Dec-01 23:24 markkuk 27-Dec-01 23:24  You should read the Introduction to PNG Features and the Rationale appendix of the PNG spec
