An assertion failure without the context (surrounding code) is meaningless. Often there is a comment in the source near the assertion that explains the problem or it is obvious from the context. Can you post the code surrounding the ASSERT statement?

If you see at the call stack, it would tell you exact reason for falure. And we could not guess it.

Two lines in edit box

I am trying to display two lines in an edit box. The edit box is checked for multi-line. The code displays the following just fine:

one two three four five six

I want it to display:

one two three
four five six

How do I do it? Here's the code I'm using:

RawString.Format("%s %s %s %s %s %s", F1, F2, F3, F4, F5, F6);
GetDlgItem(IDC_EDIT_RawBidAsk)->SetWindowText(RawString);

Thanks

Put \r\n in the string to create a line break

Thanks. I inserted the \r\n into the string and it works fine.

RawString.Format("%s %s %s\r\n%s %s %s", F1, F2, F3, F4, F5, F6);<br />
GetDlgItem(IDC_EDIT_RawBidAsk)->SetWindowText(RawString);

reading from microphone or line in plug using C++

Hey,
I need to read data coming in from a circuit into the microphone or the audio plug in C++. I looked at WaveIn** functions and the MCI library in MSDN and they all record the incoming data (sound) into a wave format, however I need to directly interface with the sound card and read voltages instead of in a wave file. Anyone knows how to do that or has examples of work done to read sound from the microphone directly from C++.
Thanks!

win32 controls not repainting when logging off then in

hello, I'm new to win32 and have created a ListBox where I'm hadling WM_CTLCOLORLISTBOX messages and setting the background color to black. The problem is, with application running and logging off then back in the list box doesn't repaint it self.

These are the steps to reproduce:

Launch application
press ctl + alt + delete which brings up the "Windows Security" dialog
press escape to cancel "Windows Security" dialog

Result:
Only the items in the list box have black backgrounds the rest of it is white?
The vertical scroll bar is not painted.

Dragging the window off the screen and back repaints the ListBox?

Any ideas???

Thanks Allan

Question about optimization of C++ using inline

Hi,

I have a callback which is a static void function, will there be any benefit to adding an inline to this?

Is there any free profilers available for Visual C++ .NET Unmanaged code?

Thanks in advance.

Callbacks are usually called through a function pointer - In that case inline wouldn't be doable
I would think.

naah. don't do it.. as inline.. as doesn't work.. as static function force compiler to behave it as function instead of piece of code to be inserted

Menu Item Selection???

Lets say there are three menu items File, Edit, View as you can see in your browser. Now my question is,

1. how to get the on click/select event of either of the menu items?(here they are popup menu's so ID's are not associated with them and we cant make use of ON_COMMAND)

2.how to get the name of the selected menu item? (here menu items are appended dynamically using MF_POPUP)

You cannot click on a pop up menu. Even if you click on a pop up menu nothing will happen..

Wouldn't you get that by uncompressing the source data?

Do you want raw PCM data?
