convert 4 chars to __int32

big_denny_20021-Mar-06 21:44

21-Mar-06 21:44

hi all

Smile | :)

I have for example 4 char variables

char c[4] = {'a','a','a','a'};

and one __int32 variable

__int32 x;

I want to write c[4] contents(binary) to x.

using shift left and & operations but I cant.

can someone help ?

Re: convert 4 chars to __int32

2 ways :

__int32 i = c[0] +
            c[1] << 8 +
            c[2] << 16 +
            c[3] << 24;

the second one is more exotic :

union {
    char c[4];
    __int32 i;
} u;

Re: convert 4 chars to __int32 [modified]

21-Mar-06 22:23

hi thank you, but first is not working ?

__int32 x = 0;
char s[4] = {'a','a','a','a'};
x = s[0]+s[1]<<8+s[2]<<16+s[3]<<24; 
cout<<x;

when i run the proram i get such output x = 0

the second variant is not working correctly too, I get output : 1633771873 instead of 3267543746

thanks

i don't know why the 1st is not working... it should !!
however, be sure that that operator<<() is overloaded for __int32

for the union solution, it works because the memory blocks overlap, so your int is automatically filled with what you write in your char[4]...

I was wrong the result was correct.

As I said I had array of four chars

char s[4] = {'a','a','a','a'}

integer value of 'a' = 97 (1100001)

theretfore the result was correct

01100001 01100001 01100001 01100001 (1633771873)

thanks to everybody

toxcct21-Mar-06 22:58

21-Mar-06 22:58

as nibu said, how can you be sure it prints the incorrect value ?

if printf("%X", x) displays 0x61616161 (1633771873 in decimal), then everything is ok (according that 'a' is 0x61)

every element in char c[4]={'a','a','a','a'} is same so little or big endian architecture is not problematic

Command line error D2016 : '/RTC1' and '/clr:initialappdomain' command-line options are incompatible

giftsana21-Mar-06 21:36

I have a simple application in VC6.0 and ported it to .NET 2003.
I set "Use Managed Extensions" to Yes from the Project Properties->Configuration Properties->General because am using #using .

i get the foll error
Command line error D2016 : '/RTC1' and '/clr:initialappdomain' command-line
options are incompatible

i saw a lot of articles on this which suggested to do the foll to solve this error: i.e.
Open the project's Property Pages dialog box. For details, see Setting Visual C++ Project Properties.
Click the C/C++ folder.
Click the Code Generation property page.
Modify one or both of the following properties: Basic Runtime Checks or Smaller Type Check

i tried changing options under Basic Runtime Checks but to no avail?
i still get the error?

How can I solve this command line error?
Pls help!

Sincerely

about load and unload library

George_George21-Mar-06 20:39

21-Mar-06 20:39

Hello everyone,

I think we can use LoadLibrary to load a .dll file and use its published interface. I am wondering whether there are some methods to un-load a library (which is adverse to LoadLibrary)?

thanks in advance,
George

Are you serious ? Have you read the documentation ? It's right there.

Thanks Rick!

This link is dealing with how to load a library. But my question is about how to unload a library.
