In my company we are selling an application which is often upgraded. Till now we had the policy to send them email that new app is awailable and they just download it from our FTP with special username and password.

But this is getting rather stupid. I would like to have auto-update build in my app.
The problem is becouse there are so many solutions for this and all of them are wierd to me.
1.) MY first idea was that i have some kind of apache-php server which would deliver my installer.exe to my app. But people say that this is inpossible in PHP. They say that it only works with browsers. (This is wierd to me too)
2.) ISAPI filter or Extension?
3.) Should I just program Socket Server and integrate Socket Client in my app?

Any idea would be apriciated.
Tnx girls & guys

Hello!

I have programmed one Auto Updater Application, Actually what the logic behind it is that my Application residing on
Client Computer, it self check for version update at a fixed interval and if it found an update it download itself new one (using UrlFileToDownload Api), after that it update itself in stealth mode (Updating on Local Computer was done by INNO Setup).

Hope this will help!

It has to have some sort of authentication implemented in client application.

All that your app has is already implemented in our client app. The problem is at the server side. I don't want to use FTP, couse it doesn't always work with different proxy settings in many companies.

I would like some alternative to simple ftp://user:pass@www.address.com.

Do you understand?

I never told you to use FTP!!,from my point view The Client application will check for Update like th Norton Antivirus work.

Like Norton Antivirus - yes that is what i want!
But how to do this on Server side?

I took a look at your function but it just download from some URL. But i wan't that this file is not awailable to anyone.

Actually i am saying tha t App at client end will check for update not server will connect to client and check for update.

like this

--Client---->Connected to Internet-->send a Request(using HTTP Transfer/XML data/POST method)-

---->SERVER-->check that new version is available-->
--->if new version is availabe->download that and update that

Simple

Hi I am doing a project in MFC which uses three MDI child windows, When i use the MDITile command, the frist opened window moves to the last but i want the windows to arrange the other way. Can anyone help me in sorting this problem?

Re: Z order

SetWindowPos() can be used to change the Z-order of a window. I'm not sure what method MDITile uses to enumerate windows, but i would try this first.

You left me high and dry and changed me You lied to me and now i’m angry...

Bitmap Picking and Moving

Hello,

After drawing bitmaps, i want to implement a functionality like picking a bitmap with mouse and moving it some other position on the client area (dragging it).

Any help?

Re: Bitmap Picking and Moving

I would try it to do it this way:

1) When clicking the left button, create a temporary CBitmap object, compatible with a memory DC. Using this memory DC, draw the wanted area on the CBitmap.
2) When moving the mouse
a) If the CBitmap was previously drawn, draw the CBitmap in its old position using a XOR mode (that is clearing the previous drawing)
b) draw the CBitmap in its new position in XOR mode
3) When releasing the left button: clearing the drawing of the CBitmap object in its old position ( = drawing in XOR mode), update the data, delete the temporary CBitmap object, redraw the window.

Whell, i'll try to explain what really i want:
I got to two OXY scales, (two dimensions). So One OXY, and another O'X'Y'. The first is local coordinate system and the second is real (global) coordinate system. I Got three equivalent points in that systems. So how to get know the position on the area, using this three point, and create projection to the real( global) coordinate system? I hope i explained it corectly. In other words i got the GPS,and the Map in Local coordinate systems, and i want to translate the data from gps, to set the point on the map correctly.... Ufff, i have to learn english better....
Please Help...

Hi,

you will search DC related information.

I had a similar problem a couple of years ago.

I ended up learing a lot of matrix & vector maths I'd forgotten about years previously.

But that was transforming points from one coordinate system to another, with O'X' and O'Y'
not necessarily orthogonal (at 90<super>o).

But if your coordinate systems are parallel, and you want to go from one system to another...
Transforming point P...

P1 = P - O
P1.x /= (OX).x
P1.y /= (OX).y
P2.x *= (O'X').x
P2.y *= (O'X').y
P' = P2 + O'

I ended up with my own matrix & vector classes, with a function that took 3 coords in one
system (O,X,Y), 3 in the next (O',X',Y') and produced a matrix to transform between them:
M = dxfMatrix::Warp(A,B,C, A',B',C')
P' = MP
But its not publishable! Maybe this counts as teasing...

If you need any specific help, let me know.

Iain.

"that was transforming points from one coordinate system to another, with O'X' and O'Y'

The transforming point from one system to another, with three or more controll points. Where can i find the formulas or something,or open source or any information

Well, I had to struggle a lot, against a lack of information. I can't email you the
code, as it is too entangled in commercial stuff & confidential. Sounds like an
article needing to be written!

If you want a head start, I would go start learning about matrices again...

reading from serial port

Hi,

OS:Win2000
using VC++ .NET 2003

I have some sample code (from msdn) to read and write to the serial port. The code works perfectly when I put it into a console program. However, when I put excactly the same code into an Windows Form Application the program "hangs" at the reading routines. Do other reading routines apply to Windows Forms Applications? I simply can´t understand why it doesn´t work...

BYTE Byte;<br />
DWORD dwBytesTransferred;<br />
<br />
// Specify a set of events to be monitored for the port.<br />
SetCommMask (hPort, EV_RXCHAR | EV_CTS | EV_DSR | EV_RLSD | EV_RING);<br />
<br />
while (hPort != INVALID_HANDLE_VALUE) <br />
{<br />
  // Wait for an event to occur for the port.<br />
  WaitCommEvent (hPort, &dwCommModemStatus, 0);<br />
<br />
  // Re-specify the set of events to be monitored for the port.<br />
  SetCommMask (hPort, EV_RXCHAR | EV_CTS | EV_DSR | EV_RING);<br />
<br />
  if (dwCommModemStatus & EV_RXCHAR) <br />
  {<br />
    // Loop for waiting for the data.<br />
    do <br />
    {<br />
      // Read the data from the serial port.<br />
      ReadFile (hPort, &Byte, 1, &dwBytesTransferred, 0);<br />
<br />
      // Display the data read.<br />
      if (dwBytesTransferred == 1)<br />
        this->label1->Text = S"string";<br />
<br />
    } while (dwBytesTransferred == 1);<br />
  }

Your main thread is blocking on the WaitCommEvent.
Typically, code like this would be placed into a separate tread where it would not interfere with the processing of other information, such as mouse movements, painting, keyboard events, etc.

Hi,

Did you mean how to select Items from the list box?

Use CListBox::GetSel function to select the current item in the list box. If you want get all the item selected from list box, you get the total number of counts use GetCount function and check all the items is whether select or not
