hi,
Pls go thru the following idea.
I have a jpeg image, and I have the details of my machine as text(Machine config, softwares installed etc.). I want to merge these two into a single jpeg file that contains the text written over the picture.
Then I want to set this image as the desktop background.
Pls give ur suggestions to implement the same in Win32 coding.
All inputs are appreciated.
Thanks in advance.

To set the desktop background from your code you can use IActiveDesktop::SetWallpaper().
As far as writing text over JPEG is considered you will have to wait for someone here to respond.
Somethings seem HARD to do, until we know how to do them.

I just tried to compile the demo projest in my machine, But it says:
"'SPI_GETDESKWALLPAPER' : undeclared identifier"
What could be the error?

What compiler? What OS? What changes did you make?

I am using Visual Studio 6.0 and my OS is Windows XP, Service pack 2.
And I didn't make any changes to ur code.

Are you using the latest Platform SDK for VS6?

It seems not the latest SDK.
Pls let me know how can I check it?

Use the Add/Remove Programs applet in Control Panel.

Exactly how is COM going to solve the OP's problem (i.e., setting image as the desktop background)?

I remember some times ago a member of code project wanted to use of IActiveDesktop but he gots an error when he wanted to use it I guess maybe SyamlalS will get this error of course I know this link is about introduction to COM but Mike on that article use of IActiveDesktop and I guess if SyamlalS gets error about use of IActiveDesktop he can refers to this article

Hi,
I want to check in my VC++ code if a file is blocked. Normally when exe files are transferred over email, they will be blocked.If you go to the property of the file, you will see "Security: This file came from another computer and might be blocked to help protect this computer" and there will be a button to unblock it. I have to programmatically check this case. Is there any API or function that could help me get this information.
Thanks in advance.

Did you look out for CDatabase class. A CDatabase object represents a connection to a data source, and allows you to operate on the data source
Best sites: MSDN Site, CodeProject ...
Best Books:This really depends upon what do you want to read. WIN32,MFC,COM,ATL etc.

Dear,
For my project, I want to write a program that receives audio signals from the USB port and simultaneously plays the audio.
In which topics should I search for help in order to write a program that generates and plays audio data simultaneously?
|
|
|
|
|
I interpret this as two different problems:- Reading the streamed audio from the USB port
- Playing the audio
Regarding problem #2 I think you can benefit from using the VideoLAN streaming server/player[^]. It listens to ports commonly used for streaming. To set up the streaming session it requires a description in SDP format sent with RTSP protocol to inform it on what ports the audio data can be read.
You have to read up on this.
Regarding problem #1 I suspect you have to write an adapter that reads the audio data from the USB port, translates it and sends it in UDP/RTP packets to ports that VideoLAN is listening to. I assume the data is coded using a common codec such as MPEG4 or similar. VideoLAN supports a lot of codecs, so just hope that it supports the one you, or your device, uses.
There's a lot to be done here, but to give you better guidance you have to describe your environment setup further: - What kind of device do you connect to the USB port?
- Can you connect to the USB device as you would connect to a serial device?
- How is the audio data formatted?
- What codec is used?

thank you for your reply.
forget anything about USB. I have worked a lot on this topic and I have no problems. the problem now is that I have some audio signals that should be played. I have two problems:
1- the audio signals I receive, have not a special format. signals are only sampled values from the voice.
2- realtime playing of the audio is necessary.

What form is the data in? PCM samples?

The samples are raw data, means that the samples are values betwwen 0.00 and 5.00, denoting voice amplitude.
|
|
|
|
|
And the samples are arriving at a defined, steady rate?
If so, then I agree with Roger - just convert them to an appropriate format of PCM (raw) samples
and it'll be relatively easy to work with them from there.

So, we've covered that. Nice!

This makes me think of treating the audio data as "raw", for which you should be able to use the WAV-format. I would try creating a memory mapped WAV-file with the raw audio data and then use the multimedia API for playing it with mmioXXXX functions.
Have a look here[^] for how to play/stream a WAV file and here[^] for information about the WAV file format.
