Jamie Hale5-Feb-02 11:21 Jamie Hale 5-Feb-02 11:21  As a software engineer, of course I agree with the whole code reuse thing. STL is a spectacular tool that I can't live without. However, given the type of questions posted here by Marwan, it looks like he/she needs a good solid understanding of the basics of the language before introducing them to the relatively complex ideas of templates. Don't you think? J Re: thank you but... Christian Graus5-Feb-02 11:30 Christian Graus 5-Feb-02 11:30  I understand that std::string is a typedef of a templated class, but would he need to know that ? I dunno, I'm all for using char arrays early on, but at this point, he seems to have a lot of complexity introduced by virtue of not using a string class. I don't think 'ground up' is always the best way to learn, that's why I am against learning C before C++. You don't need to know about templates/namespaces/etc. to learn C++, you can just find out later that using namespace std; is bad code, and how templates work, etc. I believe C++ is an excellent learning language if you use the facilities it provides and then pull away the supports as you go on to learn the depth of what it can do.

Problem with vc6 in xp Joel Holdsworth5-Feb-02 8:33 Joel Holdsworth 5-Feb-02 8:33  I've just got a new computer, and I'm using my old version of vc 6 with service pack 5 on windows xp. The problem is that it often pops up messages of this sort... http:\\joelholdsworth.members.beeb.net\strange.jpg It seems to popup when I'm altering certain files, or looking at some of the mfc sources. The only way I can get rid of it is to press the cancel button repeatedly for around 30 seconds. This is intensly irritating! Does anyone know the cure? or what its caused by, or has anyone seen this problem, because its eminantly not caused by "\Device\Harddisk1\DR1" not having a disk in it! With time we live, with money we spend! Joel Holdsworth Re: Problem with vc6 in xp Joel Lucsy6-Feb-02 4:23 Joel Lucsy 6-Feb-02 4:23  Well, it's not msdev. We have three people with XP and VC6 with SP5 and everythings ok. I'd check XP out, this sounds rather serious. Joel Lucsy (jjlucsy@ameritech.net) Re: Problem with vc6 in xp Nic Oughton6-Feb-02 4:41 Nic Oughton 6-Feb-02 4:41  Sounds more like a problem with XP or the hardware. Do you get this error with any other software running on the PC ? Whilst you say Joel Holdsworth wrote: because its eminantly not caused by "\Device\Harddisk1\DR1" not having a disk in it! at that moment in time it maybe that the PC considers that it doesn't have a disk !! We get a similar message on one of our servers which we believe is connected to the number of buffers allocated to passing data between the disks and the server, so your PC may be timing out in someway when writing to the disk. I would open it up and just check the cables as a starting point. Low Memory Message AndyC5-Feb-02 8:11 AndyC 5-Feb-02 8:11  Is there a message or some sort of event that I could catch in my app if the machine is running low on virtual memory ? Cheers AndyC Re: Low Memory Message Carlos Antollini5-Feb-02 8:26 Carlos Antollini 5-Feb-02 8:26  It's a little complicated but you can use VirtualQuery(); Regards a Good Luck... Carlos Antollini.

Re: C2601 Nemanja Trifunovic5-Feb-02 8:03 Nemanja Trifunovic 5-Feb-02 8:03  Seems that you tried to define setInitialValue etc. inside of main(). Move them to the global space, and it should be OK I vote pro drink Re: C2601 Joaquín M López Muñoz5-Feb-02 8:03 Joaquín M López Muñoz 5-Feb-02 8:03  seems like you have done something similar to this: void someFunction(...) { void setInitialValue(...) { ... } ... } this is illegal C++.

Sonork ID 100.10529 cantollini Lots of controls in a dialog bob coppock5-Feb-02 7:40 bob coppock 5-Feb-02 7:40  There seems to be a limit to the number of controls in a dialog box. It appears to be less than 255. At that point there is no warning, but the editor refuses to place another control on the window unless you first remove one. I can't find any documentation about this limit, or whether there is a way to surpass it. Any ideas? Thanks for your help bob c Re: Lots of controls in a dialog Jon Sagara5-Feb-02 7:44 Jon Sagara 5-Feb-02 7:44  Just out of curiosity, what are you doing that requires 255+ controls in one dialog? Jon Sagara What about ? Re: Lots of controls in a dialog bob coppock5-Feb-02 7:57 bob coppock 5-Feb-02 7:57  It just growed like Topsy. We are testing out a complicated piece of hardware with many motors, lasers, an FPGA, etc, with many things happening at once which need to be reported. I can break the dialog in half, of course. In fact, I'm starting to do that, but it would be nice not to have to move so much code. The present dialog box .cpp file is already about 5K lines. bob c Re: Lots of controls in a dialog Ernest Laurentin5-Feb-02 8:33 Ernest Laurentin 5-Feb-02 8:33  bob coppock wrote: The present dialog box .cpp file is already about 5K lines. Ouch! If *possible*, create child Dialog(s) and insert them into your dialog. Of course, your child dialog won't have any title bar, ok or/and cancel button. Good luck, - Dirty hands lead to important discovery... Re: Lots of controls in a dialog Michael Dunn5-Feb-02 8:11 Michael Dunn 5-Feb-02 8:11  There's a limit on the # of controls you can have in a DIALOG section in your .rc file. Additional controls must be created at runtime. --Mike-- "Everyone has figured out what 'service pack' really means, so they had to go and change the language.
