CSpinCtrl increment by 0.01

Good day to you all!
I created an application having a spin control(vertical scrollbar) attached to an edit box. I needed the application to increment/decrement by 0.01 everytime the scrollbar is pressed. Later on I found out that the default increment is set to 1. What should I do so that the increment would be set to 0.01 and also the display in the edit box having two decimal places?

Thank you very much for the help and time!

Huh?

I've never seen a spin control or scrollbar implementation that used floating point.

Why not set the range to range*100 and anytime you display the position use position/100 ?

Yes that was what I was planning to do. I just wanted to confirm if there was a possibility of using float/double inside the spin control.

Thank you for the help! Smile | :)

Active Desktop

Hello,

I have developed a Channel File that is distributed using an installation file. In order to install the File on the active desktop I use a small C++ application which does the following:

ShellExecute(NULL, NULL, activedesktop.cdf, "", "", SW_NORMAL);

When I tested on several machines on some XP it works just fine and on other it does not show the Add Item to Active Desktop dialog.

If someone has experience with the Active Desktop I would appreciate a suggestion.

Thanks, Dan.

nUser = Encode(user); // base64 encoding

Pwd = "123456";
nPwd = Encode(Pwd);

CString str;
str.Format("%s""%s""%s""%s", NULL, nUser, NULL, nPwd);//Is it right Format???

Nstr = Encode(str);

sHello.Format( "EHLO %s\r\n", local_host );
m_wsSMTPServer.Send( (LPCTSTR)sHello, sHello.GetLength() ); /////////WORK FINE

nHello.Format( "AUTH %s\r\n", Nstr );

I think u use AUTH command incorrectly.
AUTH cmd has parameter of Authentication type e.g CRAM-MD5 which is supported by server

Following example will clarify this : [C : Client S: Server]

C: EHLO jgm.example.com
S: 250-smtp.example.com
S: 250 AUTH CRAM-MD5 DIGEST-MD5
C: AUTH FOOBAR
S: 504 Unrecognized authentication type.
C: AUTH CRAM-MD5
S: 334
PENCeUxFREJoU0NnbmhNWitOMjNGNndAZWx3b29kLmlubm9zb2Z0LmNvbT4=
C: ZnJlZCA5ZTk1YWVlMDljNDBhZjJiODRhMGMyYjNiYmFlNzg2ZQ==
S: 235 Authentication successful.

Hope this will useful to u ...

250-ETRN
250-STARTTLS
250-AUTH DIGEST-MD5 CRAM-MD5 LOGIN PLAIN
250-AUTH=DIGEST-MD5 CRAM-MD5 LOGIN PLAIN
250 8BITMIME

after this i issue AUTH CRAM-MD5
i get 334 PENCeUxFREJoU0NnbmhNWitOMjNGNndAZWx3b29kLmlubm9zb2Z0LmNvbT4=

But when i send user name and passward i get again 334 with some value like above

I have a MFC Dll project in Visual C6 and use CAsyncSocket class in my project.
in wizars forms set "windows socket" checkbox, I get a object from CAsyncsocket and create this, I export function , when use this function in delphi or other programming language I have get one error.
I debug my Dll and see occur error in myCasySocket.create() line.

void CreateMySocket()
{
CAsyncSocket myCasySocket;
myCasySocket.create(); // << when in line run in DLL occured Error
}

Thanks,

Well, that's nice but more information about the exact error you get would be nice. Is it a runtime error (I suppose so because you said that you try to use the dll in delphi, meaning that you probably compiled it successfully).

Also, when you post code, use the pre formating tag (juste above the emoticons).

Just guessing, since you haven't indicated what error occurs...

The DLL uses MFC so are you initializing MFC properly for a DLL?
CAsyncSocket, by default, requires a window (used internally by the class) so there can
be problems if MFC is not initialized.

Right. But, CAsyncSocket is an MFC class, so MFC needs to be initialized on the DLL.
Also, you'll need an MFC message loop on a thread somewhere to handle the windows messages.

Why not just use the Sockets APIs? CAsyncSocket is just a thin wrapper around them anyway.

You'd need to understand sockets to use CAsyncSocket as well.

Failed to remove/rename the file using remvoe()/rename()

char folder[] = "C:\\My_Folder\\";
char *oldFile;
int old = 1;
sprintf(oldFile, "%sMyFile%02d.xml", folder, old);
if( remove(oldFile)
{
sprintf(text, " { Error } Failed to remove %s.", oldFile);
LOG(text);
}

Even "C:\My_Folder\MyFile01.xml" is valid path, remove() failes to delete this file.
What should I use?( file is not read-only )
Why failed to remove the file?

Sorry to all.

Once the file opened to read data from it was,t closed properly. Because of which problem was generated.
Now it's working fine after closing the file properly.

Thanks to all of you.
