This example shows how to manipulate button ideal size by specifying a fixed size.
class ButtonSubclass {
public:
ButtonSubclass(HWND hWndButton) {
SetWindowSubclass(hWndButton, MyButtonSubclassProc, 1, (DWORD_PTR) this);
}

There will be times where you only want to import a specific sheet from an excel file with multiple sheets. To do that, we'll use "SHEET=".
PROC IMPORT

DATAFILE= "myfolder/excelfilename.xlsx"

Using PROC SQL is a good way to get quick results from a table and throw them into variables. I usually find that when I want to get a count of records I just loaded to a table, I can get that count into a variable with a quick PROC SQL call.
PROC SQL;
SELECT
COUNT(*) INTO:aVariable
FROM

Here follows a example of what can be done with nested StackViews, giving the user the impression of a continuous scrolling experience using complex user interface elements or alignments.
A frequent question about StackViews inside Scrollviews comes from ambiguous with/heigh alerts on interface builder. As this answer explained, it is necessary to:
Add in the UIScrollView a UIView (the contentScrollView);
In this contentScrollView, set top, bottom, left and right margins to 0
Se...
The big gotcha about scrolling is to determine the offset necessary to present (for instance) a Textfield inside a StackView with is inside the ScrollView.
If you try to get the position of Textfield.frame.minY can be 0, because the minY frame is only considering the distance between the element an...
LINQ queries do not execute immediately. When you are building the query you are simply storing the query for future execution. Only when you actually request to iterate the query is the query executed (e.g. in a for loop, when calling ToList, Count, Max, Average, First, etc.)
This is considered de...

The MIDI Thru is simple and easy to test. When working properly you will be able to install your Arduino project between two MIDI devices, MIDI IN to MIDI OUT and you will be able to verify that the two device operate together. If you have the ability to measure latency, you will see an increase d...
For example, imagine a screen with 3 sections, laid out like this:
The blue box might be given a margin of 4,4,0,0. The green box might be given a margin of 4,4,4,0. The purple box margin would be 4,4,4,4. Here's the XAML: (I'm using a grid to achieve the layout; but this design principle applies...
To generalise what we've demonstrated above: individual things contain a fixed margin of "half-the-whitespace", and the container they are held in should have a padding of "half-the-whitespace". You can apply these styles in your application resource dictionary, and then you won'...
Sometimes Android's logcat is running infinitely with errors coming from some process not own by you, draining battery or just making it hard to debug your code.
A convenient way to fix the problem without restarting the device is to locate and kill the process causing the problem.

Let's first create a simple "Hello world!" MailboxProcessor which processes one type of message and prints greetings.
You'll need the message type. It can be anything, but Discriminated Unions are a natural choice here as they list all the possible cases on one place and you can easily us...
You can asynchronously return a value for each processed message if you send an AsyncReplyChannel<'a> as part of the message.
type MessageWithResponse = Message of InputData * AsyncReplyChannel<OutputData>
Then the mailbox processor can use this channel when processing the message to...
