Thanks for your interest and attention, chandu004.
I will tell you the result when I complete the draft coding, currently I am writing the parser to read data into memory.
regards,
George

Cool chandu,
I must study your code and post my code when I complete the parser code.

The compiler does it the same way you do when you initialize the
array.
A pointer to the indexed array element is formed by multiplying the indexes
by the associated array dimension(s). In your example, to get the
value in the array at p[x][y], the compiler creates code to calculate
a pointer to the value
tmp = p [x][y];
ptrtovalue = ptrtoarraystart + ((x * arraydimension1 + y) * sizeof(int))
tmp is asigned the int found at ptrtovalue

Thanks Mark,
I do not quite understand why using int (*p) [10], I think using int* p is fine without changing the other parts of the program, agree?

My requirement is to record a voice file from a web apllocation in the following format..,
"PCM 8kHz, 16 bit, mono"
1) I imported the winmm.dll
DLLImport("winmm.dll", Entrypint:="mciExecute", charset:=charse,ansi, set last error:=true, Exact spelling:=true) private shared function mciExecute(byVal lpStrCommand as string) as boolean<br />
end function
2) opened the audio device
mciExecute("open new Type waveaudio recSound")
3) setting the format of voice file
mciExecute("set recsoud time format ms bitspersample 16 channels 1 samplespersec 8000")
----> after executing this last statement, I faced the following error "The specified parameter is out of range for the specified command". I am able to record voice file at 11.25 khz fq, and even at higher fq. with the same above mentioned steps.
is there any other way to meet my requirement, for the last 10days I was browsig, no where I found proper solution,
thank u all,
with regards,
kiran

I haven't used MCI in a looong time, but are you sure all your strings are right?
mciExecute("open new type waveaudio alias recSound")
mciExecute("set recSound time format milliseconds bitspersample 16 channels 1 samplespersec 8000")

Actually, I am able to save my voice file in 11.25kHz fq, and above fqs just by changing the set parameter values. It works fine. But I need to save it in 8000 hz format.
Yes I am using these statements in VBScript.

I previously posted a simular question and received some interesting response.
I have 7 pages within a Wizard. On each page there are 8 - 10 Editboxes that are NOT set for tab control. There is nothing else on the property page besides the Editboxes.(no [OK], [Start], etc.)
If a User selected with the mouse the 5th Editbox on page 2 (IDC_TIRES), entered some data, then selected the [Next] or [Back] button on ther Wizard, OR selected with the mouse ANOTHER Editbox on page2; I have no idea how to get the data. Using ONSETFOCUS or ONENCHANGE only tells me activity has occured within the Editbox, where ONKILLFOCUS tells me the User is no longer using the Editbox. When ONKILLFOCUS occurs I could get the data IF I had control of the page. How can I get control of the page is my question. snippet code please!
-- modified at 21:32 Friday 9th November, 2007
I did in the "Class Wizard" under CPage_2 class, select each IDC_ ???? box and added a function for it. So Editbox 5 is IDC_TIRE and the function name for it is CPage_2::OnTire() .
I thought I would gain control this way but it didn't give me control.

Assuming you have a CEdit member variable assigned to each edit control, just use the GetWindowText() method.

But what message is OnTire() associated with?

I guess I'm not very good at explaining what I need. Picture yourself as the User. You see an Editbox for Tires with the instruction to enter the SN# or Part#. You enter it and then either select another Editbox on this page(2) or click [next] and go to the next page (which the page knows nothing about). Where and when in the class (CPage_2), if such an activity occurs, am I to do the pRdit->GetWindowText().

When you switch from page #2 to any other page, page #2 will receive a PSN_KILLACTIVE notification.

Okay, What about if thye User selects another Editbox on page 2?; or has to look up the part number and takes an excessive amount of time finishing part number/ID entry. How will I know to capture the data? Code please.

Look for EN_SETFOCUS and EN_KILLFOCUS.

David,
When the "Class Wizard" creates a class for the Property Page is creates the constructor, and several other functions for the class. If I select ON_EN_SETFOCUS, ON_EN_CHANGE, ON_EN_KILLFOCUS, the Wizard gladly creates these functions - all have "return"s as the last statement. Again, neither of these functions would give me control of the page. Once the User has selected(clicked on) the editbox a ON_EN_SETFOCUS message is sent to the page, the same once the User selects another editbox on the page a ON_EN_KILLFOCUS message and another ON_EN_SETFOCUS message is sent ALL WITH RETURNS. I at no point receive control of the page on either selection. I need to be able to know (1): that the User is using a editbox (ON_EN_SETFOCUS does that), (2) That the User has finished entering the data (ON_EN_KILLFOCUS does that - IF ANOTHER editbox is selected). but I don't kn ow how to capture those messages and use them to collect the data. Can you show me with code as to how I would get the data? I'm sorry, but I just cannot fiquire out how to use the messages to transfer the messages into a function of my own to capture the data. Please explain with code examples.

What I'm trying to say (and don't know how) is I don't know how to get the data, if nany, once the User is finished. There is no [Finished] or [OK] button or any other type of button on the page. Just the 8-10 editboxes. I know I can know when a User has clicked on a editbox(ON_EN_SETFOCUS), and I know I will know when the User clicks on something else (ON_EN_KILLFOCUS); but how do I trap(capture) these messages and have the page jump to a function of my creation, ie.:"CPage2::GetDataFromEditBox()". I'm no understanding the "return" statements of ON_EN_SETFOCUS" and ON_EN_KILLFOCUS. I can't, anywhere on the page say, "If ON_EN_SETFOCUS == TRUE then go here; because I don't have a method in place to be able to say that. In other words, the page is running without control until such a time as I can get the page to go to a function of my creation? Understand? Afterall, on a page there can be no "OnCommand" function to release control to a function.

Use ClassWizard (Ctrl+W) to create handler functions for those messages.

No, but don't get discouraged just yet.

I tried that and nothing is done. The function the Wizard made is there, but since a property page cannot have (at lease it's not present in the class wizard ie WM_COMMAND) a OnCommand function the function is ignored when the User selects it. I checked under DeBug, the function is not called at all. Create a property page yourself and check it out, then you'll understand what I'm saying. The Class Wizard creates the function for IDC_TIRE ("CPage2::OnTire()"), but the program does not go there when IDC_TIRE is selected.

Why do you need, or even care about, an OnCommand() function? What are you wanting to use it for?
Larry Mills Sr wrote: ...but the program does not go there when IDC_TIRE is selected.
Are handling the EN_SETFOCUS message?
What does the message map look like?
