K. Shaffer13-Mar-03 10:59 K. Shaffer 13-Mar-03 10:59  Ok, I need to purchase a compiler to develop software that will need to run on Windows 98, 2000, and XP. Problem is is that the computer that I need to compile my code on is Windows 98, and Visual C++.net requires XP, 2000 or NT. This computer has had XP installed on it before and had so many problems that I had to install windows 98 back onto it. Would I be better off purchasing Visual C++ 6.0(there are still a few vendors that sell it) or getting a machine that will actually run XP? Also, why is Visual C++ 6.0 so much more expensive than Visual C++.net? Kevin Shaffer Student of Computer Science University of Kansas kshaff03@msn.com Re: Visual C++ 6.0 or Visual C++.net?

(developer, enterprise, academic, etc.). some of them contain VB, InterDev and other things. i hear good things about VC7, but personally i can't stand it. MS radically changed the IDE from VC6 to VC7, and for an old timer like me (started with VC 1.5), the new IDE looks and feels like VB Gone Wild. the VC7 C++ compiler does have some improvements over the VC6 C++ compiler, but i've never run into any situation where it mattered - the things VC6 can't do are somewhat esoteric, at least to me. so, to me, VC6 is the only way to go. but, if the price difference is great and you have no previous VC experience, VC7 will probably be fine for you. -c Image tools: ThumbNailer, Bobber, TIFFAssembler Re: Visual C++ 6.0 or Visual C++.net? K. Shaffer13-Mar-03 12:13 K. Shaffer 13-Mar-03 12:13  I was actually looking at Professional, which the cheapest one I could find is at 224.00(brand new anyway). .NET is at 89.00. I also came across an acedemic version of 6.0 that retails for less than 100.00. Is there any reason why I wouldnt be able to use this version? I do plan on distributing this as a product, so I am very hesitant to purchase an academic version, but if it works, why not? All the program has to do is read a .dbf file and send characters through a serial port. I'll also need some GUI stuff too.

Chris Losinger13-Mar-03 12:25 Chris Losinger 13-Mar-03 12:25  224 is pretty cheap for professional, since it contains VC++, VB, FoxPro, InterDev and VJ++, and a full MSDN library. the $89 VC++ 7, on the other hand, just has VC7 (plus the IDE and maybe some MSDN stuff). the full VS.Net (pro, enterprise, etc) has VC, VB, C#, and all the other junk and costs many hundreds of $s. the academic version should be fine. i think there are legal restrictions on what you can do with it, but no functional restrictions. be sure to check which version it is, tho (enterprise, pro, student, etc.). the student version, i think, has limited functionality. (student != academic) -c Image tools: ThumbNailer, Bobber, TIFFAssembler Re: Visual C++ 6.0 or Visual C++.net? K. Shaffer13-Mar-03 12:29 K. Shaffer 13-Mar-03 12:29  Cool, thanks for your help!

Makes me think we should be expecting the IDE to lift it's top and show the underlying source code.

Even if you were running an NT flavor, I'd still say get version 6, the IDE in v7 is awful IMAO. --Mike--    THERE IS NO     THERE IS NO    BUT THERE IS MAGIC PIXIE DUST  BUSINESS GENIE  CODE PROJECT Homepage | RightClick-Encrypt | 1ClickPicGrabber Re: Visual C++ 6.0 or Visual C++.net?

ATC13-Mar-03 9:32 ATC 13-Mar-03 9:32  Hi, We are using Visual C++6.0 (with InstallShield), because we want to build a distribution application that using MS Access through DAO (Dynaset). When we try to use InstallShieldWizard ... we could not see the option DAO/JetEngine template ... as InstallShield 5.1 Professional! My question is: Can we do Visual C++ 6.0 with InstallShield Wizard ... or we must use the InstallShield 5.1 Professional (or 8.0) for our distribution application? I appreciate anyone who knows detail about this issue, Many thanks Returning a file name RalfPeter13-Mar-03 9:20 RalfPeter 13-Mar-03 9:20  How can I check for the existence of a file in a directory?

My implementation does not work - I am running Visual Studio 6.0 Here is a snippet: myEditCtrl.ModifyStyle(GetStyle() & ~WS_VISIBLE, WS_CHILD | WS_TABSTOP | WS_GROUP); Please help - Thank you Re: CEdit set it to invisible and visible Chris Losinger13-Mar-03 9:07 Chris Losinger 13-Mar-03 9:07  how about myEditCtrl.ShowWindow(SW_HIDE); and myEditCtrl.ShowWindow(SW_SHOW); ? -c Image tools: ThumbNailer, Bobber, TIFFAssembler Re: CEdit set it to invisible and visible Brian Shifrin13-Mar-03 9:17 Brian Shifrin 13-Mar-03 9:17  ->myEditCtrl.ModifyStyle(GetStyle() & ~WS_VISIBLE, WS_CHILD | WS_TABSTOP | WS_GROUP); Oh my, ModifyStyle(StylesToRemove, StylesToAdd); In other words you are removing all styles but WS_VISIBLE and adding WS_CHILD |WS_TABSTOP | WS_GROUP... Should be: myEditCtrl.ModifyStyle(WS_VISIBLE, NULL); Re: CEdit set it to invisible and visible GWENJi13-Mar-03 9:32 GWENJi 13-Mar-03 9:32  Thank you guys for all of your help! I tried doing: myEditCtrl.ModifyStyle(WS_VISIBLE, NULL); but it does not work. The ctrl is initially set to visible. Anything else you can suggest? Re: CEdit set it to invisible and visible Christian Graus13-Mar-03 9:36 Christian Graus 13-Mar-03 9:36  Do what Chris said, it's the easiest and most correct way to do it. myEditCtrl.ShowWindow(SW_SHOW), myEditCtrl.ShowWindow(SW_HIDE) Christian NO MATTER HOW MUCH BIG IS THE WORD SIZE ,THE DATA MUCT BE TRANSPORTED INTO THE CPU. - Vinod Sharma Anonymous wrote: OK.
