I would want to load an image from a fixed path. This image changes every time, so I thought not include it like as a static resource. any idea?

Your question is a bit unclear. Are you wanting to load a .bmp file from disk at runtime, or are you wanting to embed a .bmp file in your application at compile time?

Ya !!
I'll try to explane the problem! I have two application:
- the first saves a .bmp, overwriting hold file, into a directory every about
5min, the image comes from a camera.

- the second must shows that image (something like a "refresh") pushing a button.
I tried but the image loaded doesn't change.

Can you halp me with a council?
thanks !!

Put a static control on your window/dialog, and associate a CStatic member variable with it using ClassWizard. Use SetTimer() to create a timer event every 300000ms (five minutes). In the event handler for the timer, call LoadImage() to load the .bmp file from disk. Using the returned handle, then call CStatic::SetBitmap() to associate the new bitmap with the static control. Make sense?

Hi!

is it possible, to make a castType from _bstr_t to "int"?

Thanks, hanno

Can't you just use atoi()?

Don't know what you like to achieve, but if you are up to put a integer value into a string a type cast is the wrong way. Use atoi() to convert character arrays to integers.

Hope this helped you out.

I just know sub window need ID to call some function.
does the main window need a ID? and where does the ID come to play?

Is IDR_MAINFRAME represented main window? does operation on main window need the parameter IDR_MAINFRAME?

Internet access application

Hi all,

My problem is like this

Connect and create session to the webserver using https
Get local binary data (any file) and upload this binry data on webserver using the above connection.

After searching through MSDN i found 'MFC sample TEAR' and its working fine to connect and get data from server.

but it works only when direct internet connection is available (no proxy),
And it fails for proxy or firewall authetication.

also i dont know if this sample supports 'https' or not.

i want to establish all these connections through my application

my application should check if proxy is enabled or not
(i think which can be easily done by getting default browsers settings from registry)

and ask user to enter proxy login and password. then i should able to connect internet using these information.

can any one suggest solution for my problem?

Thanks in advance.

I don't know the MFC sample TEAR but as my experience shows these examples seldom use ssl connections. If you want to setup a https (ssl) connection take a look at openssl http://www.openssl.org/.

A simple connection through a proxy (non-authenticating) is quite easy. First setup a simple connection to the proxy (you need a ssl connection if the proxy is https protected, too) and send a http request as explained in the codeproject article HTTP Tunneling (HTTP Proxy Socket Client).

Hope i helped you out.

Hi walter,

your first point is solution for my question.

also tunneling will work fine.

but as i said i want the user to go through authentication process of proxy server and not bypass them.

user should be prompted to enter proxy user name and password.
this will be done by prompting dialog box.

then i need to use these info to access internet.

Any way your first point is main part of my application,
hope i will find answer for my second part of question.

Thanks a lot.

If service side is behind a router, port mapping to
global IP must be done. Otherwise, we must use
relay server (or proxy server) to copy packets to
the service side.

Some technology may overcome it. Namely, even if
service side is behind a router, with their library
communication can be done without neither port
mapping nor relay server.

Do you have such know-how?
