If you want different CFormViews in just one Application, this[^] will help you.
If you want an Application to call another application, then you should use ShellExecute or thread functions.

Hi all,
Is there anyone who knows add-in for VC2005 to make snapshot of current project before serious changes made to the project?
Regards,

How about using a source control system ? That's what they are (partly) made for.

I agree -- version control is what you need! Most of us can't live without it...
Commonly what you do - is store all of your code and project materials in it's special database. As you make changes, you check-in those changes to the master copy -- which lives on a server.
You can also create branches -- which basically makes a snapshot of the master. You can then work on the snapshot, make changes and check them back in without altering the master.
Once your happy with your changes, you merge them back into the master... incorporating these changes in one transaction.
Within the masters, you can record labels (put down a marker) and also do all kinds of reporting -- like who changed what or when did this change...
There's various products out there -- some of them are more difficult to manage. I currently use SVN... have used CVS and Microsoft SourceSafe.... SVN is the best so far... but any idiot could install a SourceSafe system...
I know there's other choices out there.

Dear all
i have the following class header
#include "stdafx.h"
#include < iostream >
using namespace std;
class test
{
private:
int n1;
int n2;
public:
test(int n1,int n2);
output(std::ostream& outs);
};
VS 2005 display the following error
error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
for
output(std::ostream& outs);
any tips
i searched the net and i didn't find any solutions
thanks all
bye

you have to have a return type for your class methods.
Use void if there's no applicable type...
class test
{
private:
int n1;
int n2;
public:
test(int n1,int n2);
void output(std::ostream& outs);
};

So I have following problem (all of these are Win32 app, all MFCs, Visual 2005 applications, C++)
Application A (third-party) uses two of our dlls (which are plug-ins for A), let's say AppAplug1.dll and AppAplug2.dll. These dlls use another of our dll, Common.dll.
Version 1.0 of Common.dll is installed in AppAplug1.dll's directory, and is loaded using /DELAYLOAD by AppAplug1.dll
Version 2.1 of Common.dll is installed in AppAplug2.dll's directory, and is loaded using /DELAYLOAD by AppAplug2.dll
When I debug into AppAplug1.dll code, some function calls jumps into Common.dll Version 1 and sometimes into Common.dll Version 2.1, which brings upp following problems: some static variables are then initialised by a function call in Version 2.1, and used in Version 1, in which they are then not initilaised -> bad !
I thought processes would have their own memory space, how come I can "exchange" data like this ? How can I avoid that ?
Thanks,

can't the 2 DLLs using Common.dll use the same version, so, mount a one a only version of the DLL ?
|

Nope, because customers have different versions of the .dlls.
Plus, this would not solve the problem: I tested it with App2 using the same version of the .dll (but not the same .dll, so two .dlls in two different locations), and it failed, since App1 and App2 seem to access randomly to either the one or the other Common.dll.
C'est la merde.

hum, yes, i was thinking indeed to point to the same and only DLL file (by saying "version")...

You've only mentioned one process. DLLs are not processes -
they are mapped into a process' memory space.
This is truly DLL hell, but it seems like it could have been avoided.
A true "common" dll should be just that - common. Why is there more
than one version, in more than one place?

As Mark said, they do have unique memory spaces. You only have one app, therefore only one process space. Your problem is that you've managed to get two DLLs with the same names and the same entry points loaded into the same process space. What's a poor OS to do? I'm not surprised it's confused.
The "correct" solution to this is to have one and only one copy of your DLL (version 2.1) on the system (in system32 preferably) and to maintain support for version 1.0 inside your 2.1 DLL by using new names for functions that have changed or been added since 1.0. You know, like all those FunctionNameEx routines in the windows DLLs.
If you have functions with the same names that do different things in your two versions on an existing system, and the two plugin DLLs depend on the different functioning of the same-named functions and are trying to find a fix without making a coding change, IMHO you are up the proverbial creek without the proverbial paddle. You've got to resolve the ambiguity of which DLL / which function is which and I can't see a solution without a code change.
However, your third-party has obviously come across the problem and will be expecting some fix from you so you have the perfect opportunity to make that code change and fix the root issue.

I don't know who down-voted you; i find your comments rather accurate, and helpful.

just for the info, it is deprecated to put applicative DLLs into the system32 DLL. this folder is dedicated to the system itself. to place his common.dll file, he should create a common/ folder into his Program Files installation folder to place any shared components and libraries there.

I am facing now with this part of the project. I have put all the files in the same directory (there are 2 exe, 3 dll, 3 txt, 1 ini, 1 lib, 1 h) (although I think the .lib and the .h are not really needed once compiled and working)
With so few files... Should I create different directories?

don't confuse the installation paths, with the source code paths.
i used to have my projects organized like this:
source files organized by separating objects layer, data access layer, computing layer and presentation layer. all these in a root folder called src/.
when i compile, the binaries are generated into a bin/ folder (at the same level that src/), and the extra lib files are written in a lib/ folder.
when i have a multiprojects solution, (mainly one or more dlls + one or more exes), i let the .h files of the dlls in their original place, and configure the dependant projects to point there.
once everything is compiled, I install my applications in program files/a_name_for_the_app/...
in the case of the OP, he as several dlls (lets say, used by several exes), which uses a common dll. he could have organized it like this :
program files/
|_ the apps/
|_ app1/
| |_ app1.exe
| |_ app1.dll
|_ app2/
| |_ app2.exe
| |_ app2.dll
|_ common/
|_ common.dll

Does anyone know if the CAPICOM API comes default with Windows? The MSDN pages seem to say that it's part of most current Windows installs:
Redistributable
Requires CAPICOM 2.0 or later on Windows Server 2003, Windows XP,
Windows Me, Windows 2000 Server SP3 and later,
Windows 2000 Professional SP3 and later, Windows NT Server 4.0 SP6a,
and Windows 98.
Redistributable
Requires Internet Explorer 6 SP1 or later on Windows 98.
DLL
Requires Capicom.dll.
That would suggest, to me at least, that most computers have it. However I searched for Capicom.dll on my machine (windows XP SP2, up to date with patches) and it wasn't there.
Is this something you have to manually install?
