Can't you use some preprocessor code in Alphabet's stdafx.h file?
Something like:
<br />
#ifdef NEW_ALPHABET<br />
<br />
#pragma comment(lib, "B.lib")<br />
<br />
#else<br />
<br />
#pragma comment(lib, "D.lib")<br />
<br />
#endif
You'll have to have the correct header files included, and have the directories where those headers and lib files live included in the project settings.

Yeah this can surely be done.
What you do you had a new project settings by Build->Configuration.
You simple need two sets of entries one that involves B and other that involves D for compilation and linking.
Do the appropriate changes in the project setting to link the proper libraries... And also set the appropriate dependancies.
this way you will ignore the build of the project that is needed and plus you will not have any confusion during each build on which lib file was linked.

new to makefiles.
Heres my problem:
I used an xstring (custom) object in a class myClass, which has a functionality test fMyClass. In the makefile I did:
fMyClass.x: $(proj)/fMyClass.o myclass.o
$(CC) -o fMyClass.x fMyClass.o myclass.o
fMyClass.o: $(proj)/fMyClass.cpp
$(CC) -c $(incpath) $(proj)/fMyClass.cpp
myClass.o: $(proj)/myclass.h $(proj)/myclass.cpp $(cpp)/xstring.h $(cpp)/xstring.cpp
$(CC) -c $(incpath) $(proj)/myclass.cpp $(cpp)/xstring.cpp
and it gives me errors like:
Undefined first referenced
symbol in file
operator<<(ostream &, XString const &)myclass.o
XString::~XString(void) myclass.o
XString::XString(char const *) myclass.o
I do have xstring.h included in myclass.cpp.
What do I need to fix here? The fMyclass doesnt use xstring, but myclass does.
thanks,
ns

Hi ns,
Don't you need also to include an additional xstring.o entry and add it to fMyClass.x?

Thats exactly it!! I had been trying different places to put in the xstring.o but it didnt occur to me to add it to the fMyClass.x line as well. Many many thanks!

Can some one tell me, How do I pass Typdef name which is stored in string variable to be passed to as a functions parameter.
For eg: LOOKUP_CODE (which is a typedef for struct)
LOOKUP_CODE MYCODE[]=
{
{0, _T("1234")},
{1, _T{"3455")},
{NULL ,NULL}
}
I use to call my function, which takes the first parameter of LOOKUP_CODE
MyFunction(MYCODE,....) This works like charm.
Now I'm storing that name MYCODE into string variable strCode
LOOKUP_DEF Class = reinterpret_cast<lookup_def &="">(strCode);
and calling the function like this:
MyFunction(&Class,...) but it does not work correctly. Any input from any one is greatly appreciated.

I really cannot make sense of what you're trying to do. Maybe you could post some more code illustrating your problem?

How would I pass the name of typedef which is stored in string variable as a parameter to an function which accepts the typedef data type?
For Example:
Name of the typedef is CODE, so the function will be called like this MyFunction(CODE).
What I'm trying to do is store the typedef name in string variable StrCode then call MyFunction((Type cast) strCode).
Question is how do I type cast the string variable to typedef in this suitation, I tried using reinterpret_cast, but it did not work.

This is called run-time type information (RTTI) and C++ generally isn't designed for it. The main reason was IMHO that well-designed program can do without RTTI, and accomplish this features by polymorphism etc. But, especially when you read objects from stream, RTTI is necessary.
VC provides the typeid operator and type_info class, but this is a nonstandard C++ extension. And it can be used only for opposite direction (convert typename to string).
So you probably have to write your own class, which manages a mapping from strings to typenames. Various libraries uses various techniques for RTTI. MFC does it through a massive macro gymnastic; a month ago I made RTTI for a particular purpose via templatized class factories...
These techniques are quite complicated to describe it here, so I could send you some tips by email. I don't know about any standard technique, but I'm quite interested about it. If there's anybody, who knows more, let me please know, we can discuss

<br />
An unhandled exception of type 'System.TypeLoadException' occurred in proj1.exe<br />
<br />
Additional information: Could not load type _TREEITEM from assembly proj1, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null.<br />

I am using Visual C++ 6 on Windows XP Professional.
I am busy writing an Application Wizard. On two of the dialogs I have an edit control that must initially must be displayed as disabled. After the user makes a certain selection then the edit control is enabled.
I have tried using GetDlgItem() and a cast to CEdit followed by called ModifyStyle on the CEdit control with WS_DISABLED as the first parameter and NULL as the second. However when it comes time to enable the control, it doesn't appear to be enabled even though one can enter text into it.
Help!! Any ideas?
I am the handsome one in the crowd.

For CEdit, have a look at CEdit::SetReadOnly, and for the other controls, CWnd::EnableWindow.
To get the control, GetDlgItem should work.

Hello,
I have an MFC application that has several buttons on it that correlate to a counter being increment on a standard left click. I was wondering if there was a way to differentiate between a left click and right click. If so the left click would incremente the counter while the right click would decrement the counter. I know how to do this in C# but sadly not in MFC.
Thanks

you can try this
int min=10;
int max=30;
int randno = min + Rand()%(max-min);

You'd need to use min + rand()%(max-min+1), otherwise, 30 would never appear in the result set.

Hi all,
How I can make a win32 Callback function as a data member of my class?
I tried it making a static function but then i can't acess the data memeber of my class.The callback function is keyboard hook proc function?
<br />
class MyClass<br />
{<br />
static LRESULT CALLBACK MyKeyboardProc(int nCode, WPARAM wParam, LPARAM lParam);<br />
}<br />
<br />
Myclass::MyClass()<br />
{<br />
m_Hook = SetWindowsHookEx(WH_KEYBOARD,MyKeyboardProc,NULL,GetCurrentThreadId());<br />
}<br />
Any idea?
Thanks in advance.

Hi Hspc,
thanks for reply. The link which you have send primarly talks about making the callback function as a static member function of class but what if I want to access the class data members. any pointer to that will be a valuable inputs.
Again thanks in advance,
Abhishake
