Excel- howto turn of fake SDI mode

either go with a more bonafide SDI interface like Word (which is still a bit of a hybrid...), or keep a real MDI interface. Don't half ass it.

So frustrating that I can't put a spreadhseet in my main monitor and another spreadsheet on my secondary monitor. But at least I can keep the number of entries when alt-tabbing down by killing the fake SDI mode:

Model Driven Architecture Tools

Though it seems the MDA tools are really setup for enterprise software I still think its an interesting concept.

Best of the MDA tools looks to be androMDA, and also heard several recommendations for MagicDraw.

It won't be as bad as you fear or as good as you hope, but it will take twice as long as you plan.

It's definitly a difficult task to handle the input of so much data, but there's got to be a better way...

awk: max error

here's a humdinger of my own devising which prints out the max absolute difference between host and target calculations on a math engine calculation I think may be out of spec:


....
TestFirEngine.h:667: Trace: "input: 0.0005 host: 0.0223607 target: 0.041757"
....
$ nmake run | awk '/input:/ {x=$4; hY=$6; tY=$8; l= sqrt((tY-hY)*(tY-hY)); if (l>maxDelta) {maxDelta=l; maxX=x;}} END {print maxX, maxDelta}'

listening for device removal / insertion

It's not necessarily a SetupDixxx function as I had thought.

RegisterDeviceNotification is the magic word.

const int DEVICE_NOTIFY_WINDOW_HANDLE = 0x00000000;

void registerDeviceNotification(QWidget* mainWindow)
{

NotificationFilter.dbcc_size = sizeof(DEV_BROADCAST_DEVICEINTERFACE);

NotificationFilter.dbcc_classguid = GUID_DEVINTERFACE_USB_DEVICE;

HANDLE result= RegisterDeviceNotification(mainWindow->winId(),
&NotificationFilter,

if (result == NULL)
cout << "Can't register for notification!" << endl;

}

bool winEventFilter(MSG * msg, long * result )
{
bool functionResult= false;

cout << endl << "device insert!" << endl;

else

Breaking News: Java doesn't have it all figured out

So, I could live with the frustrating fact that JComboBox and JList don't have consistant interfaces, but then I see that the SelectionChanged event gets fired twice when a user selects a new item in a list view. Why? What's the point? There should be two events, like mouse up and mouse down.

Code to get around this:

public void valueChanged(ListSelectionEvent e)
{
System.out.print( "list select: index: " + list.getSelectedIndex() );
System.out.print( ", value: " + list.getSelectedValue() );

// below indicates how to differentiate mouse-down from mouse-up

if (list.getSelectedIndex() != selected_index)
{
System.out.println( " -- mouse down" );
selected_index = list.getSelectedIndex(); // reset
}
else {
System.out.println( " -- mouse up" );
System.out.println( "-----------------------------------" );
}
}

MSVC++ application distribution

In the MSFT jargon I guess this is called deployment. I just can't figure out why it's such a PITA to make your software run on all versions of Windows.

Update!
The one true link to deploying the latest CRT dlls in your VC++ app installation:
http://msdn2.microsoft.com/en-us/library/ms235291.aspx

But you don't get this file when you download VC++ Express. So instead you can cook up this MSI install file from the merge files.
Or can goole for a reputable, but non microsoft source.

But it gets even better- you can't run this vcredist_x86.exe without first upgrading to MSI installer 3.1 if you're on an older Win2k machine

staticl linking VC++ libraries

ahh, the old /MT flag. Hopefully it will allow me to run stuff compiled with MSVC-8 on old Win2k boxes that don't support SxS assembiles.

A good resource on side by side assemblies:

SxS side by side assemblies don't work in Win2k

I don't know why it's so difficult to make a staticly linked, dll free program with MSVC tools.

MSVC 8 is great, but it really wants to make SxS side by side dll assembiles. WinXp only support isn't going to fly for me.
