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.

Thanks.
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?

I think it just as likely says the opposite.

Is saying that on those OSs [whatever] requires CAPICOM. The logical reason for saying that is because it's not there by default.

OK. I looked a little more and it does appear that it's an optional add on. So it would appear that if you don't want to be bothered with installing anything, then you either use the .NEt API's or the raw Crypto API.

New appended menu items are disabled, though I've used MF_ENALBED.
What I want to do is like this:
Get strings from the database, then append menu items using these strings.
When I select the string in the menu, I can get the string when processing the command. In fact it is simple, but I think MFC makes it harder. Any easy way there? Thanks very much.

how? We don't know what you did if you don't post some relevant code.

Yeah, but that's not fair, Mike. You actually had to search for that, which takes time and effort. Hardly something that is considered easy.

I'm guessing MFC is "helping" you by disabling menu items that there's no
command handler (or enabler) for.

Did you declare any event for these items?

Im not sure about the relevance in your problem, but a menu item that is not related with any function is always disabled. If you append the items to a menu, but you dont connect it with any called function / message... I think you won't be able to have them enabled

Hello everyone,
I am using Visual Studio 2005 to debug a Pocket PC 2003 application on Poacket PC 2003 SE Emulator (I am using ARMV4 architecture). When using F5 to execute the application, the break points I have set before debug (F5) becomes, the information from the break points is,
--------------------
The breakpoint will not currently be hit. No executable code is currently loaded at this location.
--------------------
I am setting the break point to the 1st line of main function. I am wondering what is the check list to solve this issue to make the application debuggable?
thanks in advance,
George

(1) i want to change a 32bits color bmp image into 8bits color bmp image,
anyone who has the source code?
(2)as to 24bits image, one pixel has 3 bytes, the 3 bytes respectively is the B ,G,R value, how about the 32bits iamge? from low byte to heigh byte , what is the value of the 4 bytes?
thanks

RGBA. A = alpha = transparency
the only free RGBA to 8-bit code i'm aware of is part of one of the LibPNG utilities.

hey Chris Losinger, i only know the concept of alpha, but would you please give me the detail explain of it? why 32bits iamge has the alpha value?
as your reply, the sequence for the 4 bytes value of every pixel is R ,G, B, A, but i did an example, only the sequence is A, B , G ,R, the output image is well, what is the matter?
thanks !

Lao Wang wrote: why 32bits iamge has the alpha value?
the alpha byte controls the transparency of that pixel - it allows the background to show through that one pixel.it's useful if you want to create images that can blend with their background, or that don't have straight edges.
Lao Wang wrote: only the sequence is A, B , G ,R, the output image is well, what is the matter?
the actual order will depend on the application or API that creates or uses the image.
