I would suggest you to buy a good book on MFC. You can take the input in an edit box and display it anywhere you wish.
You need to google first, if you have "It's urgent please" mentioned in your question.

hi
If u are using MFC...you can do the following
Cin:
1)Put some controls in dialogbox like textbox etc.
2)Bind variables to that controls
3)When somebody types into that text control ,you can get the values into the variables using unctions like UpdateWindow etc
Cout:
1)You can put a static control on dialog and display message(use SetWindowText API)
2)Use a Simple MessageBox
3)Draw Text on the dialog (not needed here)
some links:

Hope that helps

Use SetWindowText() and GetWindowText().

hi
i would like to know if whether the size of datatype C++ is dependant on which of the following ( or on all of them ) ?
1)Operating System
2)Hardware Architecture
3)Compiler
Eg:Does size of int on 64 bit Hardware with 32/64 bit windows varies?

size of int is depend on Compiler.
Compiler is depend on Operating System.
Operating System is depend on Hardware Architecture.

According to the C spec, int is a convenient size for that system.
char, short and long are always the same size. Not so sure about float and double...
As for structures, they can also vary, due to structure padding.
That should give you enough google material / questions to ask your teacher.

3)Compiler
The data-type size is primarily specified by the compiler. The size used by the compiler will be chosen to make implementation of the data-type easy. So, on a 16-bit processor, ints are likely to be 16-bit, while on a 32-bit compiler, they're likely to be 32-bit.
When you get to 64-bit hardware, you have more choices. 32- or 64-bit ints are natively supported, but you'll probably find they choose 32-bit integers because a) that is in general big enough for most applications, and b) 32-bit ints are half the size of 64-bit ints - moving all ints to 64-bit would probably cause space and speed (because you have to read twice as much memory for ints) issues. You still, of course have access to 64-bit ints through __int64 and long long.
QuickDeveloper wrote: Eg:Does size of int on 64 bit Hardware with 32/64 bit windows varies?
I don't believe so. IIRC, the 64-bit Windows API uses 32-bit integer values and 64-bit pointer values, compared to 32-bit Windows, which uses 32-bit integers and 32-bit pointers.
[bit later]
I've just checked (by compiling with the x86->amd64 cross-compiling version of VC++ and looking at the generated assembler) and VC++ does indeed use 32-bit integers for x86 AND x64.

Hello All ,
I want to get information of machine which are connected in lan like there ip address ,mac . in vc++. How should i go
|
|

There's a lot of "depends" here.
Are you in a workgroup? domain? Active directory? You could loop through all ip addresses in your subnet, ping them to see if they exist... But I doubt you could get their mac addresses.
What about firewalls?
There's a reason it can take explorer a long time to fill in the network neighbourhood list.
You've chosen a difficult problem. I'm struggling to think of a requirement for other machines MAC addresses that's not (a) naughty (b) best written on sevre software by someone who knows more about this than I do (which isn't toooo hard)

Have you tried NetServerEnum()?

Yes Sir I also tried it NetServerEnum() but it is not listing ip of windows or linux machine in lan .

It's not supposed to. Use gethostbyname() for that.

Are you asking how to know if a machine is Linux based on its name or IP address?

Can you see those 5 Linux machines using Windows Explorer (Network Neighborhood)?

Hi,
im trying to create a key along with value under registry as follows....
LPCTSTR data=_T("HKEY_CURRENT_USER\\Software\\Siemens\\Tester\\Test");
CRegKey::SetKeyValue(data,_T("sample"),_T("SampleTest"));
The above gives error like....
error C2352: 'ATL::CRegKey::SetKeyValue' : illegal call of non-static member function...
pls help me out...
|
|
|
|
|
Of course your code is like this
CRegKey p;
p.SetKeyValue(data,_T("sample"),_T("SampleTest"));?right

I suppose he has to open the key before writing to it.

Well, the message is clear: you need an object, instance of the CRegKey class, and call its SetKeyValue method.

Thanks for ur reply...
Ya tried what u have suggested the issue i need to create Tester\\Test key under HKEY_CURRENT_USER\\Software\\Siemens and SampleTest(key value) under Test key...and when i tried the above function im getting Abort Message Box...i think this function creates value only under existing keys....
Please correct me if im wrong...

CRegKey's Create method looks promising...
