I created a DLL class library DLLA by puting DLLEXPORT in each class.
#ifdef _EXPORTING
#define DLLEXPORT __declspec(dllexport)
#else
#define DLLEXPORT __declspec(dllimport)
#endif
It's okay. However, now I create another DLL called DLLB, which uses the classes in DLLA. what should I put in the header file for my classes ? the same ? then should i define _EXPORTING in project setting ?

You could define the symbols as _EXPORTING_DLLB and _EXPORTING_DLLA - that would keep the differentiation

Umm...how on Win9X? EnumProcess seems to work only on NT.
|
|
|
|
|
Use Process32First/Process32Next from the Toolhelp API. I wrote an article about an enumeration class that works on both NT and Win9x here.

Hi,
I am having a MDI application. I want to fix the positions
of Child windows, that are seen in the MDI.
Can someone please tell me how to do it.
Thanks,

Intercept (and respond to) WM_GETMINMAXINFO for the child windows.
However, if all of the child windows are going to be fixed size it seems you really are not interested in having an MDIClient.

Where can I find the files needed by App Wizard to generate and app in Swedish, norwegian and danish.
Happy programming!!

I am not sure what files you are referring to, but you should be able to find what you need in the Global Software Development section.

Under the MFC\include and MFC\source I expect to find a directory L.sve containing some RC files in Swedish, and similary for other lanuages. I would also like to ensure that App Wizard adds the option to the combobox for selecting languages.
In the long run I will be writing my own add-in so that the skeleton app will include the default menu and string table for the 13 lamguage our future projects will have to support.
Happy programming!!

Well, *uck me.
Today VC7 decided to act up on me, in a big way. It won't let me edit my resources anymore; it gives me a "can't find afxres.h" message.
Here are the symptoms (long):
- afxres.h is where it should be
- does not happen on a fresh project
- worked before
- Happened for the first time when I was doing a search/replace on resource IDs, but I ignored it; it came back later. Can't remember if I was able to access the resource file in between those times, but I believe I did.
- Resource file compiles fine.
- If I replace resource.h and *.rc with another pair (from my new project that works), I get the same error.
- I've rebooted
- I've cleaned all my temp files.
- If I remove the reference to afxres.h, it complains about the next #include file (whic is also available and located in a dir that is referenced in te Resource Incudes list
- changing Resource Includes has no effect
I am clueless on this. Can anyone help?
TIA x 10^6

Richard,
You wrote: "If I create a new C++ app or dll and try to open the .rc file
in recource view I get the RC1015 compiler error. The programs compile
just fine so the directory paths have to be OK, it only happens if you try
to edit the .rc file."
You potentially could be running into a problem with the Resource View that
happens when you have a lot of VC++ Include Directories. Try reducing the
number of include directories in Tools | Options | Projects | VC++
Directories | Include files.
Also, it may be possible to add the directories back after you successfully
expand the resources in resource view. The project has an APS file that it
uses for the resource view. Once that APS file is created, it doesn't go
through the same process when expanding the resources. So if the include
directories are all necessary, you could remove a few, expand the
resources, and then add them back. I know this is not ideal, and I
apologize for the inconvenience. I have reported this problem.
Thank You.

Is there such a flag for sharing image list for a CTreeCtrl? If not, how would I force the Tree Ctrl to not destroy the Image List?
|
|
|
|
|
You need not worry; tree controls have this behavior by default. In fact, i am not aware that it is possible to disable it, so you must always destroy the image lists used by a tree control manually.

First I thought this might a direct translation of a greek poem. Then I saw Shog's post. Anyway its a work of art. I wish you good luck in your future attempts at verse? It's poetry isn't it?

I am in need of a Multi subitem selection Tree control. Does anyone have any ideas for a good starting point or even an existing one.
Happy programming!!

Programmers Paradise has the Visual Studio.net Professional upgrade for $195.99 after a $300 rebate. Any better offers out there?
Do not quite understand why Code Project is offering the full version of Visual Studio.net for $799, when most of us only need the upgrade, and we do not need the "extras" from Dundas and Wintellect. Perhaps Code Project can give us a great deal on the upgrade too?

Is there a unique MFC protection that keeps an object to another class from modifying its private data?
I have a CStringArray in the my document class (single-document). I pass the CStringArray object to class function belonging to another object that I instantiate inside of the document class.
For example:
#include myOutsideClass;
void CMyClassDoc::change()
{
myOutsideClass *pClass = new myOutsideClass;
pClass->modify(myCStringArrayObject);
}
-----
// Definition of modify()
void CMyOutsideClass(CStringArray &array)
{
array.RemoveAll(); // remove all data from object array
array.Add("testing"); // insert "testing" into object array
}
-----
Notice I pass the CStringArray object into modify using reference. Function modify(CStringArray &array) can read data from the object array. However, it cannot make permanent changes such as RemoveAll(), Add(), and/or SetAt().
Is there a internal protection algorithm that keeps another object from making permanent changes to a member object? I tried declaring the CStringArray inside of CDocument in public. That does not work either. The program crashes with an *access violation* error.
Thanks,
Kuphryn
