Try a global hook.

how to perform global hook.
|
|
|
|
|
First, take a look at this article.
Next, replace the msghook function with code similar to this:
static LRESULT CALLBACK msghook(int nCode, WPARAM wParam, LPARAM lParam)
{
KBDLLHOOKSTRUCT *pkbhs = (KBDLLHOOKSTRUCT *) lParam;
BOOL bControlKeyDown = 0;
switch (nCode)
{
case HC_ACTION:
{
if (pkbhs->vkCode == VK_LWIN || pkbhs->vkCode == VK_RWIN)
return 1;
break;
}
default:
break;
}
return CallNextHookEx (hHook, nCode, wParam, lParam);
}

Do you want to hide the start menu or disable the windows key on your keyboard?

hide the popup menu when i press window key

You want to hide the menu or do you want the menu to not appear? I am assuming the later is your query. Install a keyboard hook, as Hans Dietrich already said. Look at MSDN for SetWindowsHookEx() function. Remember that your hook procedure code has to reside in a DLL and then you need to load it from an executable.

Can a hidden menu still appear, or is a menu that does not appear not considered hidden?

I wasn't clear. It should have been something like "Do you want to hide the menu that appears on key press, or do you want to suppress the key press event, so that the menu does not appear at all".

I got an usb radio and I want to keep playing music in a buffer so I can save it later. How can I do it?
|
|
|
|
|
Does the radio have a record feature?

Can't you use the windows sound panel/mixer to re-route the audio to a file ?
|
|
|
|
|
No record feature. I want to write a program to save audio but I don know about buffers. Is there any sample source code to record a playing audio?
|
|
|

Search in MSDN (or google the entire internet) for waveInOpen or waveInAddBuffer - these are some of the SDK-level Windows Multimedia functions you could use to handle.
An approach I have used in the past is to allocate a set of buffers in memory (using malloc - I code in C!) then open the wave device, and one by one do waveInAddBuffer to the audio device, and processing each buffer (copy it to another area in memory) whenever it is full and do waveInAddBuffer again. I only stored a few minutes, so I could replay a short section from PC memory, but you could write them to a file on the hard disk instead.

I had a look for a small project I wrote a few years back, but could only find a very early version that doesn't do anything.
The project recording and play using Waveform audio interface http://www.codeproject.com/useritems/julienT.asp[^] appears to do what you want, but the article doesn't really describe anything. The source code looks quite well commented. Try starting here.
If the above article doesn't help, search codeproject articles for waveInOpen, and have a look at the other sample projects that are shown.
Once you've had a look at the sample code on CodeProject, try to ask about specific problems you have.

hi,
I am using CApplication,CWorksheets,CWorkSheet classes from VC++, I need to copy a sheet into the same WorkBook but i dont know how.
Thanks

Have you looked at the documentation for the Excel Object Model?

Yes,
but all the information is about C# or VB, nothing about C++ using classes CWorksheet,CWorkBook...
I think i must use CWorksheet.Copy (Or CWorkSheets.Copy) function, but i dont now what parameters i need to send. (It ask for two Variants).

Well, the interfaces used and the flow of how to accomplish something is the same no matter what language the client is implemented in.
If you find a good example of what you want to do, but it's not written in the language you'd prefer, I suggest you study the flow and the function arguments anyway. It would get you a picture of what you need to do and in what order to do it.
You might even get a little understanding of the other language as well while you're at it and that must be a good thing, right?

I found examples in VB, but the problem it is not th algorithm, the problem is where can i found information about arguments for VC++, because it is different between C#,C++ and VB (I think, but i am not sure) to use the CWorkSheet (CWorkBook....)
I am tried:
CWorkSheet MYSHEET.copy(_variant_t(SHEET),_variant_t(SHEET))
CWorkSheet MYSHEET.copy(_variant_t(NUMBER),_variant_t(NUMBER))
CWorkSheet MYSHEET.copy(_variant_t(SHEET NAME),_variant_t(SHEET NAME))
CWorkSheets MYSHEETS.copy(_variant_t(SHEET),_variant_t(SHEET))
CWorkSheets MYSHEETS.copy(_variant_t(NUMBER),_variant_t(NUMBER))
CWorkSheets MYSHEETS.copy(_variant_t(SHEET NAME),_variant_t(SHEET NAME))

Yes they hide that information in the Documentation[^]

I already read this documentation, and i tried to use an CWorksheet element as argument for the function, but it does not work.

Before I gave you the link? Because your earlier posts said you didn't know what to send as arguments.

Obviously not, since it clearly says that you cannot specify both Before and After which is exactly what you have done in every case in the reply you sent to my post.
Furthermore the documentation says that Excel will create a new workbook if you specify neither Before nor After.
I suspect the parameters could be either integers (VT_I4) specifying the index of the sheet or strings (VT_BSTR) specifying the name of the sheet.
I haven't tried it though so I'm not sure.

I am agree with you, but i am not able to use only one argument, i dont know what i need to write to use copy with before option for example.
I tried to pass VT_I4 and VT_BSTR parameters, but it does not work.
Thanks

Try recording a macro while you're copying a worksheet.
Then you can read the resulting VBA code to figure out how to do it. You just have to translate it to C++. That's what I do when I need to figure out to do things with Excel and I cannot find an example of how it should be done, including creating diagrams.
