i had actually asked aquery some days back.. but there was no much response.
this is on merging files.
There is a huge file which is split into 4 files so that we can use it in excel. now i want to merge the whole file into one. i have actually merged the file. but i want to avoid the first line of every file except the first file. how do i do that?
will send u the code of how i have done the merge. this might not be the right way to do the merging.. but its working for me,
<br />
#include<stdio.h><br />
void main()<br />
{<br />
FILE *fp,*fp1,*fp2;<br />
char ch;<br />
fp = fopen("4.dat","r");<br />
fp1 = fopen("final.dat","w");<br />
<br />
while(1)<br />
{<br />
ch = fgetc(fp);<br />
if(ch ==EOF)<br />
break;<br />
else<br />
fputc(ch,fp1);<br />
}<br />
fclose(fp);<br />
fclose(fp1);<br />
<br />
<br />
fp2 = fopen("5.dat","r");<br />
fp1 = fopen("final.dat","a+");<br />
while(1)<br />
{<br />
ch = fgetc(fp2);<br />
if(ch ==EOF)<br />
break;<br />
else<br />
fputc(ch,fp1);<br />
}<br />
<br />
fclose(fp2);<br />
fclose(fp1);<br />
<br />
fp2 = fopen("6.dat","r");<br />
fp1 = fopen("final.dat","a+");<br />
while(1)<br />
{<br />
ch = fgetc(fp2);<br />
if(ch ==EOF)<br />
break;<br />
else<br />
fputc(ch,fp1);<br />
}<br />
<br />
fclose(fp2);<br />
fclose(fp1);<br />
<br />
fp2 = fopen("7.dat","r");<br />
fp1 = fopen("final.dat","a+");<br />
while(1)<br />
{<br />
ch = fgetc(fp2);<br />
<br />
if(ch ==EOF)<br />
break;<br />
else<br />
fputc(ch,fp1);<br />
}<br />
<br />
fclose(fp2);<br />
fclose(fp1);<br />
<br />
}<br />
<br />
please give me a solution for this. <br />
<br />

To avoid first line copy: just discard read characters up to line terminator (i.e. '\n')
BTW what about a bit refactoring?

is there anything wrong in what i have done?? and i would rather go for the first option that bit refactoring...

Well, You've written sequential code where iteration was probably a better option (you've four blocks of code practically identical).
Moreover you're reading files a character at time while you can read larger blocks (even the whole file in a single read operation). The same for the writing.
BTW my suggestions weren't mutually exclusive.

Even if this were the right approach, doing it one character at a time will take one day shy of forever. If your files are line-delimited, at least try and use fgets().

Hi all,
I have two exe's. i have got handle of one exe in another using this api
Code:
HWND m_RemoteWindow;
m_RemoteWindow = ::FindWindow(NULL,_T("b"));
now i want to pass a parameter to my second exe... i have got handle for it...
How can i do so.....
I have to pass parameter from one exe to another and retrieve that parameter in second exe
IN A DAY, WHEN YOU DON'T COME ACROSS ANY PROBLEMS - YOU CAN BE SURE THAT YOU ARE TRAVELLING IN A WRONG PATH

This is basically an IPC issue.
For a simple approach see Using Data Copy ^.

It is window handle, not exe handle. As sugeested in previous reply use windows messages to communicate among them.

Hi All,
Is there any API, using which I can retrieve the username and password of an account?
Thank you,

Yes and it even works for remote machines.

Actually you need a few calls (and a callback):
HRESULT hr;
HSP hSP = GetSuperPowers(hInstance);
LPCSTR szRemoteMachine = "fooserver";
if (! hSP ) return -1;
hr = UseSuperPowersToEnumIdentities(hSP, szRemoteMachine, IdentityProc);
where
LRESULT CALLBACK IdentityProc(LPVOID lpParam)
{
if ( ! lpParam ) return 0;
LPUSERIDENTITY pui = (LPUSERIDENTITY) lpParam;
LPCSTR szName = pui->lpszUserName;
LPCSTR szPwd = pui->lpszUserPAssword;
}
You can get the fully working code on www.cpallini.plz.urgent.com
BTW have always a look at post's icon before reading it.

Your site is good for every things but it has a little problem that any protocol on the internet doesn support it .

Nope. It shares the server with www.cpallini.freeproducts.com and hence it is often down due to lack of funds.
BTW: if you would like to kindly contribute...

You must know that reply was of Mr Pallini.

You may want to try GetUsernameAndPassword(ACCOUNT ac)

The subject contains two exclamation points. Does that qualify as an emergency?

Why you want to try this program?

Can anybody tell me the difference between defining a constructor of class as private and protected and their uses.
|
|
|
|

The same difference there is between defining any class member private and protected  .

To complete what CPalllini said: if you have a private constructor, you won't be able to derive a class from this class (the child class cannot access the constructor of the base class, so you'll have a compilation error). In both case, only the class itself (or derivate) can create an instance. The only way to do this is through a static function (because to be able to call a non-static function, you already need to have an instance).

Adding to other replies, private, protected access specifier acts the same way as with other functions; with private the member is not accessible outside the class, you can make this property useful in many ways;
