[Banfa]

The code stangely and unnecessarily casts the value returned from calling invokelicenseupdate to char * and then assigns to an int. Remove the cast.

I guess on Linux it was compiling for C99, visual C supports C89 and at line 151 you can not declare a variable half way through the code block it needs to be declared at the start of the code block (before the printf).

[ashitpro]

In function "invokelicenseupdate",
declare "licenseupdateresult" variable at the beginning of the function. i.e.

int licenseupdateresult= 0 ;
....
....
//Then use it as:
licenseupdateresult = reloadngcpe(processparameter);

Similarly at line 150 char comm[500];
At line 117:

presult=(char *)invokelicenseupdate(str,str2);

Why are you type casting it to char* ? Cause, "presult" is of type integer and "invokelicenseupdate" returns the same.

Consider these just as a guidelines...Try to solve further errors accordingly..
Google is your friend, use it !!

Looks like you have failed to include the socket library in you link command link. Try adding the winsock2 library (ws2_32.lib) to the link command.

Additionally this simple port will not work once it has link because the windows socket library does not work without initialisation.

You will have to add a call to WSAStartup in the code before any socket functions are called and you should add a all to WSACleanup once the program have finished unsing sockets.

[priyanka23]

plz tell m how to add winsock2 library in command link.....please telle me...and also suggest me how to initialise windows socket library?? nd thanks u a lot.......

[Banfa]

In the linker properties of your Visual Studio project there is a place to put additional libraries.

I told you how to initialise it, call WSAStartup, you can look the function up on MSDN or using google.

[priyanka23]

plz tell me where i will have to call WSASTART UP in my code???
Thanx a lot..

[Banfa]

Before you call any socket functions.

You first socket call looks like a call to socket at line 199. But you will be able to tell because all the socket functions will return WSANOTINITIALISED if they are called before WSAStartup.

[priyanka23]

i am not able to understand your solution please describe the solution and tell me how to initialize WSAstartUP and where.....
Thanking you and sory for distrbing..you again and again

[Banfa]

WSAStartup must be called by your program before your program calls any other functions from the socket library.

Your first call looks like it is at line 199 in main, a call to socket so before then.


If you just run the program without putting in a call to WSAStartup or if you put it in the wrong place then any socket functions that you call before WSAStartup is called will return WSANOTINITIALISED

[priyanka23]

thanks you lots..i am not understanding that how to initialise WSAstartUP function in the code as i described you....

[Banfa]

You don't initialise WSAStartup, you call WSAStartup to initialise the socket library.

If, as I said in post #8, you type "WSAStartup" into Google (or another search engine) then the first returned link will be to WSAStartup Reference on MSDN which tells you all about the function and at the bottom of the page has an example of calling it.

Check out this link:
http://www.learncpp.com/cpp-tutorial...-2005-express/

Start looking from "Step 5 C-4". See how they have added library.

Have you done it similar way?

[priyanka23]

yes ,,i have done it in similar way.....but still errors coming...

[Banfa]

priyanka23:yes ,,i have done it in similar way.....but still errors coming...

If you don't describe the errors you are getting we can't help fix them.

Help us to help you by giving us all the information you have not making us have to drag it out of you 1 drop at a time.

[priyanka23]

before calling WSA startup function calling similar errors were coming and after calling WSA startup function and adding library ws2_32.lib according to you..i m getting same error..and i have also posted whole changed code..
ERROR----

[Banfa]

I gave the answer to this 5 days ago in post #6.

You are not including the library ws2_32.lib in your link command. That library is the one that contains the Winsock library which is the implementation of all those functions.

[priyanka23]

I have already added ws2_32 library in link command as u suggested.....but still errors occure

[ashitpro]

Open your .vcproj file in text editor.
Copy everything and post here. (under code tags)

Lets see how it looks !!

[priyanka23]

should i have to post the code agin which i hv changed aftyer wsa strt up call...???wat u mean by .vcproj file?/

[ashitpro]

No I don't want code..

Go to your project directory and search for *.vcproj
See, if you get any such file

THE REQUIRED .VCPROJ FILE IS AS ABOVE.

[ashitpro]

OK...This is user file..this is not what I want.
I need project file..

I have a project on my machine. Its name is "Configurator"
When I enter in to project directory, I see some files.

Configurator.vcproj.NESS.P7105893.user
Configurator.vcproj
Configurator.sln
Configurator.suo
Configurator.ncb

You should find similar files under your project.
I am expecting "Configurator.vcproj" file. you have sent me .user file that is first one.

[ashitpro]

How do you building the project? Under 'Debug' or 'Release' mode?

[priyanka23]

under Build tag using build solution...

[priyanka23]

under Build menutag using build solution...

[ashitpro]

Go to
Build->Configuration Manager

Look for "Active Solution Configuration"

Tell me what is it?

[priyanka23]

under debug.....

[priyanka23]

in debug mode.....

[ashitpro]

Here is the last step I can suggest.

Go to:

Solution Explorer->(right click your project that is 'license')->Properties->(On top left corner there is 'Configuration')->Select 'All Configurations'

Then on same window go to:
Configuration Properties->Linker->input

under 'Additional Dependencies' put 'ws2_32.lib'

Click OK

Now, go to Build->(Instead of 'Build Solution' try 'Rebuild Soulution')

[priyanka23]

thanks a lot.. but i hv already done evry thing....but plz help me bcz i hv to submit my project widin 2 days...plz............

[ashitpro]

try adding 'WSock32.Lib' under linker->input->additional dependencies.

Keep ws2_32.lib

[priyanka23]

i have tried it also....but i noticed that placing WSA startup call at different places different errors are coming.......
