Who can to explain me step by step what I have to do ???? thanks;) Re: Thank you very much !! and another simple question , Please help ! Ben Burnett8-Jul-01 12:24 Ben Burnett 8-Jul-01 12:24  To get your spin control to update the edit-box set it as its Z-order to the next number after the edit-box(Specify Z order by setting the tab order). After you have done that, you should enable the 'Auto buddy' option, and if you also want the spin control to fill the edit-box with numbers you set the 'Set buddy integer' option(these can be found on the control property pages -- Alt+Enter). Hope this helps. -Ben --------- On the topic of code with no error handling -- It's not poor coding, it's "optimistic" Re: Thank you very much !! and another simple question about spin! 9-Jul-01 4:59 9-Jul-01 4:59  OK ! You are right. But now I have another problem. if I set the range of spin with big numbers(as 10000) In run time I gets a MessageBox of error that impossible to return int Re: Thank you very much !! and another simple question about spin! Ben Burnett9-Jul-01 11:56 Ben Burnett 9-Jul-01 11:56  When you set the range, are you using SetRange32? If not, you should. SetRange only allows you to set 16 bit ranges (I know 10000 can fit it a 16 bit variable, but when in Rome...). Also, you should make sure the spin control’s data member is initialized to a valid index within the range that you specified. -Ben --------- On the topic of code with no error handling -- It's not poor coding, it's "optimistic" Visual C++, need help Drake Elsari8-Jul-01 5:53 Drake Elsari 8-Jul-01 5:53  Whenever I start my VCPP, before it displays the window it gets a fatal error.

Re: Visual C++, need help Ben Burnett8-Jul-01 16:59 Ben Burnett 8-Jul-01 16:59  Have you tried installing the latest SP? are you using any third-party addin's, if you are disable them. -Ben --------- On the topic of code with no error handling -- It's not poor coding, it's "optimistic" Re: Visual C++, need help Drake Elsari9-Jul-01 6:04 Drake Elsari 9-Jul-01 6:04  No, I don't use addins and my VC++ was working for like a year with SP 3. And now it just suddenly keeps giving me that error. What can I do about? Re: Visual C++, need help Ben Burnett9-Jul-01 12:02 Ben Burnett 9-Jul-01 12:02  Hmmm... Aside from installing SP5, I'm not sure what the best approach would be. HAve you by any chance just installed some new fangled software package? Have you considered wiping your system completely clean, and starting from scratch?? – I know it’s a little drastic, but this would be my best advice to you at this point. -Ben --------- On the topic of code with no error handling -- It's not poor coding, it's "optimistic" Extra controls 8-Jul-01 2:30 8-Jul-01 2:30  Is there a way to add extra control such as a datagrid or a chart control to VC. I used to use these controls (are they OCX's?) in visual basic all the time, its not something whcih seems to be used often in vc, why is this?? ben Re: Extra controls Christian Graus8-Jul-01 2:58 Christian Graus 8-Jul-01 2:58  If you go Project/Add to project/Components and COntrols you'll find that you can add Registered ActiveX controls on your machine. I don't know if this list is dynamic or set by VC on install, because you're right - I don't use them. I prefer the control I get by building my own or getting them from places like this. An overridden MFC control has all the source, so I can do what I want with it. I remember the hell I went through wading through VB documentation on MSDN trying to figure out FlexGrid. Not for me, thanks. Christian #include "std_disclaimer.h" People who love sausage and respect the law should never watch either one being made. The things that come to those who wait are usually the things left by those who got there first. STL error syntax 8-Jul-01 2:22 8-Jul-01 2:22  is there a technique to understand stl errors?? the syntax is so odd, eg: 'class std::_Tree<int,struct std::pair<int="" const="" ,char="" *="">,struct std::map<int,char *,struct="" std::less<int="">,class std::allocator<char *=""> >::_Kfn,struct std::less<int>,class std::allocator <char *=""> >::iterator __thiscall std::map<int,char *,struct="" std::less<int="">,class std::allocator<char *=""> >::find(const int &)' : cannot convert parameter 1 from 'char [3]' to 'const int &' This particulr problem was easy to solve but the error messages are worse than useless...! Re: STL error syntax Christian Graus8-Jul-01 2:25 Christian Graus 8-Jul-01 2:25  There is a VC add in kicking around that strips the extraneous template errors so you can quickly get to the meat of STL error messages. I think it's here, but I could be wrong. Either way, it's about if you search for it ( I don't *think* I have it myself ) Christian #include "std_disclaimer.h" People who love sausage and respect the law should never watch either one being made.

I thought of a magazine, but WDJ just ran a different plug in thing, so I thought I must be wrong. Christian on Jono's machine ;0) Jonathon Visual C++ Questions 8-Jul-01 2:02 8-Jul-01 2:02  Firstly, can I ask what are library files. I presume these are .lib files - and how do they differ from dll's? Are they still C++ compiled code.... Secondly, what form does MFC take. I presume we dont actually have the classes as source code on our hard disks. Is Mfc made up of DLL's, but if this is the case how come when debugging we can drop through into the source code. I presume the MFC DLL's havent just been released as a debug version for this reason surely the debug compilation is less efficient. Third, what are macro's? Are these written in C++? i know what the traditional macro is for instance in an excel spreadsheet or the Window 3.1 macro recorder which "records" a series of actions, is a C++ macro similar. I guess its used for automating things but I dont see how exactly. And thats it, thanks a lot...! Ben Re: Visual C++ Questions Christian Graus8-Jul-01 2:12 Christian Graus 8-Jul-01 2:12  A library file is compiled code, but it is not the same as a dll. A use for .lib files is to distribute a programming tool without the source - the code will compile with just the header, as long as the .lib file is provided for the compiler to find the code it needs to finish the job. GDI+ is distributed this way. Two - yes, you have the MFC source code in /vc98/mfc/src. Now you can't complain about that !! A lot of stuff to do with extending MFC would be nigh impossible if you couldn't bury your nose in the source code for a bit... A macro allows you to create a new command, for example min and max are macros, they are defined so that you can type min(x,y) and the code is replaced on the first pass of the compiler with something like: if (x InstallShield ...

The first time you create packages, the second you say which ones you want to use. It's dumb, and not clear at all. I prefer Setup Factory.
