Use wmemset() while working with Unicode!
memcpy(m_pbytTemp,&m_pbytFileBuffer[To],From-To);
Similarly use wmemcpy() !

But m_pbytFileBuffer is of Byte *(to hold the bytes)

Then shouldn't you be using something like W2A() ?

Hi,
I am working in a project in VC++ using MFC and recently while building and linking the project I get warnings like:-
Airways.obj : warning LNK4006: "unsigned short DBP_NWPT_LON_SB" (?DBP_NWPT_LON_SB@@3GA) already defined in Airport.obj; second definition ignored
Initially i ignored this warning but as the lines of code increased beyond 3000 so was the amount of warnings that I get...
Can anyone plz help me in resolving these warnings?? I am in dire need of getting rid of them as i hav to finish my proj this week...
Thanks..
Shiva Priya

no I don't hav a second definition..thats the prob naa..
unsigned short DBP_NWPT_LON_SB;
this is the only declaration...somewhere it is getting included twice though i hav put the definition #ifndef...#endif statement..
u know any other reason due to which it gets included more than once??
Thnx..
Priya.

I guess you have declared this variable in two cpps .
Otherwise, I dont see any reason for this error.
|
|
|
|
|
have you considered usingt the extern keyword ?

this is the only declaration.
Actually that is both a declaration and a definition. You use the extern keyword to make it just a declaration. i.e.
extern unsigned short DBP_NWPT_LON_SB;
This is what toxcct was alluding to above.

When you compile a .cpp file (or a .c file) an .obj file is produced. The linker links all these .obj files together to produce the finished program. Your error message means that the file "Airways.cpp" (or "Airways.c", I can't be sure) contains a definition of DBP_NWPT_LON_SB and so does the file "Airport.cpp" (or "Airport.c", I can't be sure). The linker knows; this is the case.

Hi,
I am new to VC++ and i am currently working on a project in VC++.
I keep getting the error LNK 2001:unresolved external symbol "double __cdecl ut_asin(double)"
I get this error only while linking..not during complilation!!
I have a declaration as:
double ut_asin( double a );
whose definition is given in math.h
Can anyone help me to resolve this error??
Thanks,
Shiva Priya.

Where it is defined ? Linked is not able to find it.

Thnx for the immediate reply..
see i hav a file as ut_math.h in which the math.h file is included...
This file has macros like:
#define mqerASN ut_asin
#define fasin ut_asin
Now, I have included ut_math.h in a file called as Common_func.cpp where this method is used as:
DDIST_B = ut_asin( DDIST_SIN_ANG_SIN_RATIO * sin( DABS_ANG_B ) ) * FIXED_EARTH_RAD;
This is what I have done and I started getting the linking error.I hope you got my prob.
Thnx
Shiva Priya.

You have not answered question , where is ut_asin is defined ?
|
|
|
|
|
double ut_asin( double a )
{
if( fabs(a) < 1.0 )
return asin(a);
else if( fabs(a) < 1.00001 )
return (double)(mqerSGN( asin((double)1.0), a));
}
this is the definition of ut_asin in a file called as ut_math_e.cpp
thnx,Priya

Does this this file is included in project and compiling ?

Is ut_math_e.cpp being compiled?

Can you explain more in detail what you mean by that ? I never heard about a function called ut_asin in the math library (I might be wrong this looks strange to me).
What did you do exactly ?
You probably provided yourself a function prototype and forgot to define the body of the function. Can you post some relevant code (and don't forget to use the pre tags)

You got to understand that compiling and linking are different things and steps in building a program.
I think you got to include the lib, I guess the "math.lib" in your project settings.

Doubtful, since ut_asin() is his own function.

Hello,
I am creating a challenge response application and in that making a call to encrypt a buffer that looks like
PBYTE pBufPtr
if(!Encrypt(hKey, 0, TRUE, 0,(BYTE *)pBufPtr, &dwCount, dwBufferLen))
In this case I want to take the encrypted data pBufPtr and display it as a string to the user. So any suggestions on how I can convert the pBufPtr into a decimal number or string that can be displayed to the user for typing purposes.
Also the decimal or string value obtained by converting the pBufPtr needs to be converted back into the encrypted data for the response side of the application.
So I need to convert encrypted data into string/decimal/BCD and take that string/decimal/BCD and convert it back into the encrypted data buffer.
So please let me know how is this possible. Thank you.
