Is there any API to get outdated driver list?

Your question is vague at best.  Provide some context, please.

Hi,
I want to give audio-input to a FFT code (KissFFT) written in C, on a real-time basis. While I can give a simple test signal (like sine wave) by writing the sine function as input, I am not sure how I should convert an audio-signal (e.g.: song) into a form that can be taken as input by the KissFFT C code.
Thank you.

As you say 'real time' then I guess you'll need some electronics to convert audio to a form suitable for input into your FFT system. I once built the circuitry to utilize an Analog To Digital (A/D) chip to take an external electrical signal, buffer and interface it to a PCs data-bus and then had to write a simple device driver to enable my C++ program to acquire the sampled data and plot it in real time. With a microphone on the front that's the very basics I suppose. I guess if you really mean real time you'll need the equivalent of a sound card or A/D card, i.e. some Audio interface device that you can use to convert the real time audio to your required format so that you can grab it.

Try "waveIn FFT audio" posted here, sorry cannot copy the link.
With little patience it is workable, but also buggy.
Cheers Vaclav

I need to create a view for my document that contains a tree control and a property grid, with a splitter between them.
What do you think would be the best CView class to use as a base?
The difficult we do right away...
...the impossible takes slightly longer.

Since you will have a splitter, you first use CView to create the base view on which you create the splitter.
In the left pane you can use CTreeView for the tree.
In the right pane you can use CFormView to place the grid control.</pre>

Thank you Superman.

Start with a CSplitterWnd[^], then use the tree and form view as suggested by Superman.

Thank you, Richard. I was unaware of the CSplitterWnd class, but it ought to make the job much easier.

That's the problem with modern systems, they have so many ready made classes it's impossible to know them all.

First MIDL compiler is invoked then C++ compilation starts compiling source code for all the projects to generate .OBJ file. Then Linker is invoked to create entire application.
Isn't that right?
If it is right, then, why does linker has MIDL options?
|
|
|
|
|
Because, for instance, the linker generates type libraries (TLB files), see MSDN [^].
Veni, vidi, vici.

MSDN documentation is very poor for this subject.
I think, according to MSDN, linker calls IDL compiler to build, .c, .h and .tlb files. But it doesn't make any sense either.
I think before linking process begins, all of the files must be ready.
So I still don't understand why linker calls idl compiler.
A detailed description or reference to compilation and linking process is highly appreciated.

That information is provided by Microsoft at MSDN. If you don't find it good enough then you need to try the Microsoft forums.

i develop a update .exe and its on a web server. when i start my main program,
it'll query the version first.if there is a new version on the web server, it'll create a process and execute the update .exe. whats the update doing is that downloading the new setup.msi and setting up automatically.i use the the api MsiInstallProduct(path,"action=install"). but there's someting unfriendly,
it'll popup the setup dialog and make the user to choose to restore or to delete. how can i make it to execute reinstallation action directly. msdn says the second parameter mapping to an action,but i just dont find anyting userful. help me .plz
thank u in advance.

Instead of updating your application with an MSI, you're supposed to create a "patch". The MSI is only for installing, repairing and removing the application.
If you are only distributing an update, then use a patch instead.
What software are you using to author your MSI's?

there'r 2 cases. one maybe means a "patch" for adding some more resources.
in the other case , i need an entirely new version. my question is about the second case.
so i want to take a solution of reinstallation,though, im not sure whether its resonable or not...
and i cant understand whats ur mean about authoring my msi's.
|

Try running the installer with the "\quiet" option. This prevents any user interface.

yes,it works.there's also a doubt why i cant run the uninstall .exe if it has a different productcode from setup.msi.
and how can i get the productcode.
thank u for ur reply,its very useful
|

If you need to get the product code from the MSI, you could use the tool called Orca.
It's part of the Windows SDK: Orca[^]
You can see the contents of the MSI file with this tool.

You might want to look into this function:

I have a self-signed CA Root. An intermediate certificate was signed by this CA Root, and my server is the 3rd level which is signed by the intermediate certificate. What i have is like:
CA Root --> Intermediate Cert --> Server Cert
What i'm using is the function soap_ssl_client_context() to connect to the server and calling its web services. The function soap_ssl_client_context() requires one certificate file with PEM format as the cert file of the server.
The fact i'm facing is that, if i only put the CA Root certificate only (without the intermediate cert and server cert) in the PEM file, all the connection and web service calling are succeed. Is that reasonable? I mean it can pass the verification if only CA Root was provided. Is there anyway to make it verify the full certificate chain instead just the CA root?
The code looks like bellow:
try
{
soap_ssl_init();
soap_init(soap);
if (soap_ssl_client_context(
soap,
SOAP_SSL_DEFAULT,
NULL,
NULL,
"C:\\certfiles.pem",
NULL,
NULL
))
{
isSucceed = false;
}
} catch (...) {
isSucceed = false;
}
Any comment will be appreciated. Thanks.
