Pls use the below code......
CString csMarket = "EURUSD";
if( csMarket == Market )
{
myfile.Open("EurUsd.txt",CFile.modeCreate | CFile.modeWrite));
LPSTR buf;
int i = m_MainEdit.GetLength();
buf = m_MainEdit.GetBuffer(i);
myfile.Write(buf,i);
myfile.Close();
}

The condition will never evaluate to TRUE.

So have you bothered to set a breakpoint on the if(csMarket == Market) statement to check the value of Market? It may surprise you to find it is always equal to EURUSD.

This should probably be:
if (lstrcmp(Market, "EURUSD") == 0)
{
if (myfile.Open("EurUsd.txt", CFile::modeCreate | CFile::modeWrite))
...
}

Is it possible to create / open file in HardDisk programmatically from CD?
I want to write the application that it is to create / open file in HardDisk programmatically from CD
|
|
|
|
|
Can you be more specific you need to read from cd and write to hard
|
|
|
|
|
If I understand the question correctly...
As far as I know ... Yes it is possible.
I mean everytime you install something from a CD, the application your installing performs these actions...

yes it is possible, just the same as you would with any other exe. But if you are running software from a CD, you need to make sure it doesn't require the use of it's current directory for any temp files or writing operations.
You may also want to use an 'autorun' file, which would enable your user to run the exe without double clicking it.
|

The answer to your question is yes: you can program a virus which is distributed on CD and messes around whith the user file system automatically when it is inserted.
... and there are special locations to where you can write files that will execute automatically whenever the user's computer boots!
Isn't it wonderful? The extraordinary things one can do with computers??

I have written a Mesage Handler function ,which handles a user defined message. This function is not called for the first time when a button is clicked while it is called at all other times after clicking it for the first time. This happens in case of Windows 98 only while it runs fine on NT.

Can you please show me that function declaration and defenition

If its a user defined message, how it's getting called on button click.
Do you mean to say , you have written message handler for button click?
Can you provide some more info? like,how its created, is it on dialog , etc?

This is what i have written.
ON_MESSAGE( WM_REMIND_REGISTER_REAL, OnRemindRegisterRealOk )
afx_msg LRESULT OnRemindRegisterRealOk( WPARAM wParam, LPARAM lParam );
LRESULT CLobbyDlg::OnRemindRegisterRealOk( WPARAM wParam, LPARAM lParam )
{
if( (BOOL)lParam == TRUE )
{
// set up real money account
OnBtnCashierSetup();
}
return 0;
}
|
|
|
|
|
but OnRemindRegisterRealOk, will be called when you use SendMessage/PostMessage for this dialog( using message WM_REMIND_REGISTER_REAL).
How does it related to get called on button click? I think OnBtnCashierSetup is you button click handler.

Both new and malloc() are pretty much covered, buth I can find nothing about the other memory manipulation functions. What is the difference between CopyMemory() and memcpy(), is one safer than the other? Is one faster? Will one pay me if I use it?

Well thankyou for the very useful links, but I already know what the functions do and how to use them. My question was "what is the difference between them?"
