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.

I haven't done this. Not yet anyway.
It is a suggestion from me to you saying something like "if I were you I would try creating a memory mapped WAV-file...." in the sense that this is what I would try spontaniously if I was in your situation. But since I'm not in your situation I don't really understand your interest in my work....
Read the links I provided in my previous post.

Hi
I am getting the following when i compile my application.
SVDOFileDownLoad error LNK2019: unresolved external symbol "int __cdecl gOpenFile(char *)" (?gOpenFile@@YAHPAD@Z) referenced in function "private: bool __thiscall CVDOLanguageProvider::UseLanguageFile(char const *)" (?UseLanguageFile@CVDOLanguageProvider@@AAE_NPBD@Z)
The function gOpenFile() is being defined in another project file which has been included in the current project.Yet i am getting the error.Please help

|

link the correct .lib file in your linker options...

You included the header file which contains the function. But did you also add the cpp file in your project ?
That's probably where to problem is.
|
|
|
|
|
In "Project Propertise", Under "C++", Under "Additional Include" try to give the path of the folder that contains the file that contains gOpenFile().
|
|
|
|
|
Nope, that won't change anything: it is a linker error, not a compilation error. That means that the function is known (the header file can be found) but is not defined (either the cpp has not been included in the project or the project doesn't link against the required library).

the OP said that his function is defined in another project (so, i suppose a library project maybe...)

He said that the function is defined in another project file  . I understand it as it is in another file but in the same project. But anyway, he has now both solutions

hi, how can i achieve similar behavior as Panel control does in managed c++? user can drag the border (or near the border) of a tree control to resize it
thanks!
|
|
|
|
|
This is regular windows, not forms, right?
You can add the WS_THICKFRAME style to the tree control and it will be resizable.
You can also respond to the WM_SIZE notification in the tree control's parent
window, and in response, use MoveWindow() to resize and/or reposition the tree control.

i can't understand this:
#define IOC_VENDOR 0x18000000
where,
what's 0x18000000?
anyone can help me?
thanks a lot.
|
|
|
|
|
|
But i need to understand what it means.
|
|
|
|
|
it mean that you define the macro IOC_VENDOR which will value 0x18000000.
a #define macro replace every occurence of IOC_VENDOR in the source code before the real compilation time (this is called a preprocessor directive obviously) by the value associated...
that means, in your code, you use explicit IOC_VENDOR, but the compiler will handle actually 0x18000000 (which is the hexadecimal for 402653184).
