In addition to the other replies...
Whatever method you choose - resource-only DLL, resource includes,
etc., the most important thing is to manage IDs so they don't clash.
For example, I personally have a solution with several EXEs that share an MFC
extension DLL, and also share common code that is compiled/linked directly into
several EXEs. From the start, I set aside blocks of resource IDs for each - one block
for the shared DLL, one for common code, and one for EXEs. For new projects, I
just have to adjust the _APS_NEXT_xxx values in the resource.h file so the Visual
Studio auto-generated IDs start in the proper range of IDs.
The info in these technical notes explains the details...

hi,
i am just learning mfc and finding good inspiration with this excellent site. a question i have is that many of the dialogs and controls listed on this site are described as "owner drawn". what the heck does that mean?
is that like when you attach a control to a dialog with out using a resource?
thanks - @lrg
|
|
|
|
|

ok, thanks... so it would seem that creating an owner drawn control is useful when you need to customize the appearance of the control.
hmm... that's not what i need to do, so i will start another thread with my next question.

The owner is the program that creates the control, so it's responsible for its appearance rather than Windows.

I just downloaded a copy of VS2008. Am I alone in not recognising anything anymore. There are apparently No more Dialogs (They're called Forms? now, and are apparently created on the fly) No Resource templates, messagemaps, etc. It is still not clear to me how I trap an event, say clicking on a button. Is all knowledge of classical MFC Skills assigned to the scrapheap? To me the whole enterprise looks like Visual Basic with cpp syntax.

What edition of VS did you download (the Express one hasn't MFC)?
You have also to use VC++ and choose a Win32 Project to find the old stuff.

I have Express, so that's useless for my purposes.
btw Is that 'new' stuff realy the future? If I had wanted to write in VB and accept it's limitations, that what's i'd have done by using VB. I Don't see any point in using cpp to write stuff akin to VB. By the way, there are more limitations to Express. It is not geared for DLL's. I tried to write a simple one just as a test, Ultimately (because there were no options to choose) by changing the Output Filename to .dll. The whole thing is in a quandry since, (a process called mt is looking for it at the start of the build, and can't find it (it has not been built yet) and cancels the Process with error message c10100b1. I have sofar not been able to find a deeper meaning or background on this error message on MSDN.
Sofar I've been using Visual Studio 97 and VC++ V5.00. It serves 99% of my needs. On occasion I've had to write some DLL's to cover features not implemented on my version, but I get by.
Thanks for your reply, and a happy new year.

Well, the Express Edition has a great value for money (in fact infinite  ). Seriously, you can usually really go on without MFC, in fact I often prefer to use standard Win32 programming.

Microsoft is strongly promoting .NET Framework, i.e. managed code. It support neverthless standard C++ (native) programming while Visual Basic 6 is no more supported. Roughly speaking, .NET languages are much more powerful and really better (expecially C#) than 'good' old VB6.
Bottom line, you can really build great application using .NET.

The above is false. You can easily build a DLL (as well a Static Library) using VC Expression Edition (I've done it): just choose, as project, a Win32 one and then, in the application settings window, select DLL.

I must admit, I'm totally new to this thing. The interface has changed beyond recognition over the last few years.

I've created now about two dozen empty projects in an attempt to get the options you mention. The biggest learning experience of it all was that I'm getting a feel of the Trepidation our staff feels when I announce that their software has been upgraded. (I Never change the Look and Feel though, if it can be helped). I also noticed that All VC++ 5.0 Help (Help for my Working version)was rendered inacessable by installing V9.0.

Well, maybe in the next two dozen attempts...  Good luck!

I know this kind of feedback, it's useful.

Beacuse you are a kind developer. I usually cannot resist the temptation...

This happened to mee too (with two different version of Visual Studio). I
don't know if it is a documented incompatibility, but I agree: it is a weird thing.
Best wishes to enjoy Visual Studio 2008.

You really need to be using the full VC++ 2008 then. The Express edition will be limiting.

I went through the same feeling of being locked in VB land when going from VC++ 6.0 to VC++ 2003. I can't imagine how much of a shock it would be to go from VC++ 5.0 all the way to VC++ 2008.
I think it's the one size fits all mentality with the IDE.
The express editions only come with the libraries like .NET, but if you want the power of MFC, you have to buy one of the full products.

It is a Shock allright, I am maintaining a six year old code base. The Code runs our shops, essentially POS (Point Of Sales) Terminals.
To port this to .NET would involve at least a porting tool, as about 1500 files are involved.
We do not want or need Global Internet Access. VC++5.0 is more than adequate for this. I am now trying to write a form of Internet access, which allows customers to see their bills, and management what's going on!
VC++5.0 should be well able to do this. Maybe we should have a separate sub forum on Legacy MSCompilers, which no doubt people would find usefull.
Not everyone is writing "Push the Boundary" apps. In reality, most queeries on the CPP-MFC messageboard deals with newcommers.
By the way:
if .NET is the way forward according to Microsoft, why is VS2008 littered with JS type files!
Happy New Year

MFC is alive and well in our shop. We continue new projects in it and use VC++ 2003. Granted, there are quite a few project options but MFC is still in there. Looks different and MFC 4.2 and 7.1 differ a bit in a few places but mostly for the good of MFC. They've fixed a few problems but unfortunately ruined the IDE.
I've gotten used to it though. I still fire up VC++ 6.0 on a regular basis for some test apps but I found the VC++ 2003 compiler to smoke my VC++ 6.0 compiler by a factor or 7 to 1 even with the optimizing compiler disabled. CString is now a template class which is a bit odd but otherwise it feels the same. Some of the C++ conformance has improved allowing for some coding styles that weren't possible with VC++ 6.0.
Some things I hate: the IDE becomes non-responsive and locks up on a regular basis for 2-5 seconds, it's hardly a RAD tool anymore as it is quicker to hand code than use those bastardized "wizards" they give us, not all the tools that came with Visual C++ 6.0 seem to be included, even in the Professional Editions.
Anyway, from what I hear, you don't have to give up on MFC if you use a newer IDE. You just don't get it for free which makes sense in a way since it's really a professional's tool. I plan on going to VC++ 2008 about the start of 2009 so I hope they finish cooking it by then.
Happy New Year

Hello all,
I was spending some time making a little application that will help me a lot on save time for my future applications.
I'm creating a Property sheet application that initially will have 5 property pages.
I can add and remove some other pages, and of course it is not a big issue if they are not placed in the right order, but imagine that:
UNIT1 | second page | third page | fourth page | fifth page | UNIT2 | UNIT3 | ...
At the beginning I don't know the amount of pages I'll have, and it would be very nice to be able to add the UNIT2 and UNIT3 pages later, but having them after UNIT1:
UNIT1 | second page | third page | fourth page | fifth page | UNIT2 | UNIT3 | ...
Is this hard to do? or even possible?
PS:
I've looked into Google and in the articles regarding to the property sheets, in Google I've found tons of people asking how to change the tab order on a dialog (CTRL+D) and in he articles nothing regarding my question...
PS2:
of course I could set the UNIT1 tab at the end and "end of the story", but the fact is that UNITx should be before as their data affects the other tabs...
As always thank you in advance.

The PSM_INSERTPAGE Message[^] will insert pages wherever you want.
If you're using CPropertySheet, you may want to implement an
InsertPage() method to a CPropertySheet-derived class. See
CPropertySheet::AddPage() for details.

Hi all, i've played with/search for a solution and gotten frustrated over a problem that i have with a piece of code and i cant seem to get it down for some retarded reason.
The error is this: error LNK2001: unresolved external symbol "int __cdecl brandom(int,int)" (?brandom@@YAHHH@Z)
The code its talking about is
<br />
#include <iostream><br />
#include "header.h"<br />
using namespace std;<br />
<br />
int dport = brandom(1900, 48000);<br />
<br />
int main(){<br />
int dport = brandom(1900, 48000);<br />
cout << dport << endl;<br />
return 0;<br />
}<br />
<br />
#ifndef __RANDOM_H__ // Contents of header.h<br />
#define __RANDOM_H__<br />
void init_random();<br />
int brandom(int client,int top);<br />
int get_random_number(int range);<br />
#endif <br />
</iostream>
I've been to msdn about this stupid problem and yet i cant find out a way to resolve this. Can anyone help? Thanx in advance!
|
|
|
|

Could it be that __RANDOM_H__ would have been defined before?
Hope this helps.
|
|
|
|
|
Nope
If it was defined before, the header would have been skipped in the build of the relevant obj, and created a list of undefined symbol errors

?
If what he has written down is correct the only function that he is trying to use from that header file is the brandom one and precisely he is getting an unresolved external...
Here I'm at 3:00 AM so I'm very tired, but it seems clear to me...
EDIT: even if it is so late this is not excuse for not saying hello at the beginning and best regards at the end... sorry...

The error message is clear:
You have to link with the object (or the library) file containing the brandom function.

There are plenty of things that could be going wrong here, but my first guess is your missing a reference to a library.
If your function is from a .dll, and you have a .lib file for it, you can avoid path problems by putting them in your project directory along with the header file and include the appropriate pragma. If that eliminates the problem, then you know you had path issues and you can move the .lib file, .dll, and .h file to where you want, each time updating your path settings.
#include "SomeLibrary.h"
#pragma comment(lib, "SomeLibrary.lib")

Hi,
I would like to get hints as to how to create messages in MFC. I wanted to sense the serial port buffer and then if the bytes received is above a threshold I would like to post a message and handle it with a function. How could it be done. The main issue is creating message or events to be handled.
