 if(retcode >=0)
{
writecard(BLCK,m_Date);
}
else
{
MessageBox("Error in writing exp date");
}
now i am not able to write the data into the card run time error is coming. my full code is like this:
long CACR120RWBLOCK1Dlg::writecard(BYTE BLCK, CString strData)
{
int ctr;
int x;
//writecard(BLCK,strData) = -1;
retcode=-1;
BYTE dout[15];
for (ctr=0;ctr<=15;ctr++)
{
dout[ctr]=atoi("");
}
x=strlen(strData);
for(ctr=0;ctr<=x-1;ctr++)
{
dout[ctr]=strData[ctr+1];
}
retcode = ACR120_Write(rHandle, BLCK, dout[0]);
StrMsg.Format("Retcode:%d",retcode);
LstIndx=m_List.AddString(StrMsg);
//writecard(BLCK,strData) =retcode;
return retcode;
}
and my write function is like this:
void CACR120RWBLOCK1Dlg::OnWrite()
{
// TODO: Add your control notification handler code here
BYTE BLCK;
BYTE ResultSN[11];
BYTE TagType[50];

please help me.

F*CK !!!
did you read my answer ?????? 
edit you message and place you code samples within <pre></pre> html tags !
and read the posting guidelines too; especially the one saying that you should post relevant pieces of code, not a whole huge code file 
come on, grow up a little

it is not java code so it is in c++. i am learning VC++. so how shall i use
and ,
.please help me out.
thanku for answering to my q's,
savitri

then ? I don't understand in what my remark is related to Java !?
savitri wrote: i am learning VC++.
yes, i've figured that out for days now.
savitri wrote: so how shall i use
yes, exactly, but use <pre> to place code samples only.
and don't post your whole program code.
ask for a specific question with a small code example to illustrate your issue.

Why did you have to post this much of code? If you keep repeating your mistakes, people will start to ignore you and then you may have no option but to buy a book.  (No more free help? OMG!)
Please only post the piece of code that is relevant to your query.

hey, asking codeproject is not an alternative to buying a book !
she should really buy one and learn from there...

What is the equivalent function for 'ln' in math.h?
|
|
|
|
|
log
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

This is going on my arrogant assumptions. You may have a superb reason why I'm completely wrong.

log() is the neperian logarithm.
log10() is the base 10 log...
|
|
|
|
|
Which one to use for 'ln'.
|
|
|
|
|
re read my post, try to understand what I said and you will find.
ln stands for Neperian Logarithm (or Natural Logarithm)...

don't bother, it wasn't for you...
|
|
|
|
|
Then why did you write here?
|
|
|
|
|
it was for CPallini. don't you see the hierarchical presentation of the thread ?
|
|
|
|
|
If someone asks 1+1 = ?
You will say 1+2=3 and then 1+1=2.
So i dont want other story i just need answer for my question ok.
As a code project member u should hold your mouth.
You too learned from some one isn't it?

|
|
|

wow wow wow, man, if you want to go that way with me, you didn't choose the right person to fight against.
ok, my english is not perfect, but I sure help people here, and i do my best to make better the level of knowledge of everybody in this forum.
you asked for the function to use to make a ln(), and if you look closer, you'll remark that no only I gave you the answer, but I too gave you an explanation of what it is, and where is the difference with the other log functions.
so if you're not getting the teaching tip I gave you, it's sad for you, but don't tell me to "hold my mouth", because everything I said at first was to help you.
and for your information, I've been coding in C/C++ for more than 10 years, and i sure know where are the common beginners mistakes.
now, if you can't stand my help, just don't expect me to help you anymore...
