Thanks guys, all nice suggestions
Will try

why would this dialog never make it threw the if-else. I watch it and it starts from the top each time and will never go away.
void CAMID::OnSetfocusVelocityKt()
{
CNumEntry dlg;
if(dlg.DoModal() == IDOK2)
{
}
else
{
return;
}
}

Maybe it's this ....
are you sure the ok button has the IDOK2 id, or IDOK ???

doubled checked it - its IDOK2

Your OnSetfocus handler is called when window receives focus. Then it shows modal dialog, and after closing this dialog focus returns. Your handler gets called again. Then it shows modal dialog...

that makes total sense. lets see if I can remedy it now.
thanks for the help.

Tomasz has explained why the dialog keeps popping up infinitely. But here is something elsein that code of yours that's a little worrying. But the return value you check for is IDOK2. If you really want the DoModal() to return something out of the normal set, you'd have to call EndDialog explicitly passing the return value you want to return! I thought I'd mention that before you run into some unexpected behaviour!

Thanks, I will certainly look into this.

I started looking into another way to call this dialog, but I can't seem to find one that will
I can use. The OnFocus seemed to be the perfect on, but that caused problems.
How can I get this box to work on a click?

Hello
Not a long ago I got a task to write a programm, that solve a frequency of sound card. All colculations must do in real-time.
It's a my first project of that type and I not totally undestand how do it. May be it's programm had already done In this case would you be so kind as to write a text of programm or send to my e-mail.
Beforehand thanks for all.

I'm not clear what you're asking. What do you mean "solve a frequency of sound card"?
|
|
|
|
|
Sorry, I mean calculate a frequency of sound card.
|
|
|
|
|
It still doesn't make sense. A sound card has no frequency since it's not a waveform. Perhaps if you told us what you really want to know about the soundcard someone could tell you.
|
|
|
|
|
Sound is consist of many frequencies. Spicer has only one frequency. I need to find the total value of frequencies. Have you ever seen WinAmp? In this porgramm use this tecnilogy. We can see a waveform.
How can I get it?
|
|
|
|

I'm still not sure if you want the FFT spectral analysis or just the oscilloscope-like view. For the latter you only need to sample the amplitude and display (or whatever you want to do with it).
But without any further information on what your requirements are it would still be guesswork.
What exactly do you want to be able to do? Do you want to be able to capture a perfect digital copy, or is it OK to loose a couple of samples here and there? Do you
need to capture the sound played from any program (probably needs kernel hacking), or do you have access to the (source code to) the program that is to play the sounds?

For example we attached a microphone and shouting to it.
In the monitor must be animation of wave that utter from us.
With help this we can automatically colculate the frequency of sound
How can it do?
In the beginning we can use the MP3 file.

Ahhh, that's quite simple. Have a look at any of the sound recording examples. There are quite a few samples of this around the 'net, not to mention there is at least one sample in MSDN.
To plot your curve you just use the sample value as the y-axis and your time-step as the x-axis (probably wrapped at the right edge of your view). The same for analyzing a stored sound that your program is playing.
But to do this for another application playing a sound, no matter what API that app is using, I think you're either looking at some kernel hacking, or a simple analogue cable between your soundcards output to its input (so that you can get the sound recorded - you can AFAIK only record incoming sounds, not outgoing).

How can i return a recorset from a Stored procedure ?
rs = Cmd1->Execute(NULL,NULL,adCmdStoredProc);
why is this allways returning a closed recorset?
thanks

Every SELECT statement in a stored proc generates a recordset (except SELECT statements that assign their columns to local variables). You can navigate through the recordsets using the NextRecordset method.

If the SELECT statement returns no rows (or there is no SELECT statement), it returns a closed recordset.

It is a lovely language, but it takes a very long time to say anything in it, because we do not say anything in it, unless it is worth taking a very long time to say, and to listen to.

the stored procedure works fine now 
but when I insert something in a temporary table inside the sto proc, it stops working and the recordset is closed
create table #x(value Text)
insert into #x values('')

Maybe you could use a secondary stored procedure to do your INSERTs? Just a suggestion.

if i drag a 'Rich Edit 2.0 Control' onto any of my CDialog based forms and then call DoModal() the dialog never appears.. if i take the rich edit out and call DoModal() the dialog pops up fine..
i've traced through the code and the constructor is called both ways, but the OnInitDialog() is never called if a Rich Edit 2.0 Control is in the dialog.. ive tried it on 2 existing dialogs i have and it does the same thing both ways..
has anyone tried to use this rich edit control under .net? i've never used one before, but all im doing is draging it onto the dialog.. get rid of it and it the dialog works..
im really confused, i've had enough of this junk for this week.. 
-dz
-edit-
p.s. im trying to write a dialog that takes a string (with multiple lines using '\n') and display it in a CEdit, or rich text control so that i can display some text to the screen.. and then have a print button which prints the text.. my problem is that when i set the CEdit to the string i get little boxes where the carriage returns should be.. so i thought i would try the rich edit control.. now that i cant get that to work im trying the cedit again, but i dont see a command to make it go to the next line.. any other suggestions?
p.p.s. poping up notepad would be fine too, but the commands to start a new process take about 10 parameters.

Try calling AfxInitRichEdit() in your App's InitInstance() function. If you take a look at your output window (when running under the debugger), and see a "Dialog creation failed" or similar message, the above should solve your problem.
Peace!

Check the KB article Q166132. Or just call AfxInitRichEdit before DoModal.

You need to use '\r\n' instead of '\n' for strings passed to CEdit.
