Re: Problem with spanish accents (new point of view)

Hi all

Thank you everyone for your replies, but unfortunately they could not help me to solve my problem. However, I have been trying different things, and now I have a new point of view of my problem.

The string I get from the "receiveString()" function comes from a ms-dos console (it is a client-server communication). The problem is that this console uses CP850 instead of CP1252, which is the correct one for Windows.

So, my new problem is, how do I convert a string with cp850 to another string with cp1252?

Thanks in advance.

Regards,

Aitor

You can use OemToChar() or OemToCharBuff() for this.

I should have noticed that it was a code page issue when you mentioned that it looks fine using printf() in a console window. D'oh...

Hi,

Here is the issue:
- I am uploading a big file into a server using ftp
- on the server, a process will start processing the file as soon as it detect is presence ( even incomplete file )

is there any why that this process can guess whether the file is finished uploading or not?

thanks in advance.

What I'm suggesting isn't very sophisticated but...
you can make an empty second file with the same name and some identifying string after you've finished uploading the big file and make the server process look for it. So if your big file is named bigfile.dat, then then your process should look for a file named "bigfile.dat.isreadyforprocessing", then you remove the last part of the name, delete this empty file and you have the name of the file you should be processing.

There is sufficient light for those who desire to see, and there is sufficient darkness for those of a contrary disposition.

This also may be simple, but couldn't you just try to open the file? If the ftp server is still adding data into it, your exclusive-share-read open will fail? Just try later!

Or add the .readyforprocessing file thingy - it's cunning as well as simple!

At startup, you can check to see if file exists. If it does, bypass password dialog.

Hello,

I am having a child dialog as my current window. On top of it i open a new dialog with 2 buttons. Now what i want is that the user should not be able to work on any other dialog box or application until and unless he clicks one of the two buutons of the topmost dialog box.

This is the declaration of it rc file

IDD_ACCEPT_REFUSE_DLG DIALOGEX 0, 0, 233, 46
STYLE DS_SETFONT | DS_MODALFRAME | DS_FIXEDSYS | DS_CENTER | WS_POPUP | WS_CAPTION | WS_SYSMENU
CAPTION "Live2Support"
FONT 8, "MS Shell Dlg", 400, 0, 0x1
BEGIN
    CTEXT           "",IDC_STATIC_MSG,8,5,223,10
    PUSHBUTTON      "Accept",IDC_ACCEPT,56,31,59,15
    PUSHBUTTON      "Deny",IDC_DENY,118,31,59,15
END

and this is how i am creating and showing the topmost dialog box.

CAcceptRefuse* ptrAcceptRefuse = new CAcceptRefuse(this,_T(""),k,stOperatorDetails.strOpSessionId,stOperatorDetails.strOpName,m_strSiteID);
							ptrAcceptRefuse->Create(IDD_ACCEPT_REFUSE_DLG,this);
							ptrAcceptRefuse->ShowWindow(SW_SHOW);

Please Help Me

Why don't you use a modal dialog box instead of a modeless ?

If you don't know how to create a modal dialog box, I think you REALLY need a good book about MFC, because this is really the basics. Take a look at the DoModal function (if I remember correctly, people have already suggested that earlier, so why didn't you do it ?)

You have to create a modal dialog box. See the literature for DoModal()

Somethings seem HARD to do, until we know how to do them.

DDX control type variable in a dialogbar

ilgale12-Oct-08 21:35

I've problem using DDX variables for controls in a dialogbar.
In VC6 it was possible to associate a DDX variable (control type)
to a control being part of a dialog bar. In that way, I could
perform an override of some control's functionalities using
a MyClass instead of the tipical control class.
So... in VC6 there was no differences between Dialogs and DialogBars
with DDX controls.
Now I work in Visual Studio 2008. It seems that I cannot create
a DDX variable (control type) for a control being part of a dialog bar.
Is it true ?
If I force it using Attach and Detach methods, it still doesn't work
(MyClass instance doesn't receive Windows messages sent to the control).

How can I specialize the behaviuor of a control being part of a dialog
bar in Visual Studio 2008 ?

which should use pipe or socket at Client-server

Hi All,

I am working on a client server application.

I am having a challenge that i have to serve the 250 client concurrently. Each request takes 2-5 second to execute at server side.

For this what should i use 1 PIPE implementation or SOCKET with a queue? and why?
Which performance is better.

Thanks

i think if you have to use udp mode, socket might be better.
otherwise i am afraid pipe is better because you just open and close a connect with every client but there would be more operations for socket.

just my own opinion.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
