I usually create my OC and bind it in the "Loaded" event; be it a window, user control, stack panel ... depends on your app.

https://docs.microsoft.com/en-us/dotnet/desktop/wpf/advanced/how-to-handle-a-loaded-event?view=netframeworkdesktop-4.8

"Loaded" can be called multiple times based on the scenario; so you need a "flag" in those cases to say you have already "initialized" in your code.

Your "t" elements don't match:
t=0:1/fs:nCyl*1/f;
x=sin(2*pi*f*t);
versus
double t = Math.Sin(freq * (2 * Math.PI) * (phasecent) / samplerate);
double x = Math.Sin(2 *Math.PI*freq*t);

You start with a "bill of materials". You can't just build things in any order. Check out car web sites; they show how to put a car (order) together.

You're using a wrapper; no one can tell what's going on. You should be able to treat the SD card as a removable disk, if at all.

Too much going on. Create the database; wrap that up; then move to the next stage / step. Your "create database column" process could benefit from a "for loop" based on column count.

"Calculate" implies a formula; you do no calculating and show no formula so one can't tell what you want to "calculate".

A 1 ms timer tick is like "1000 frames per second". You should start by dialing it back to about 50 FPS. VR runs at 90 - 120 FPS.

You query the data, not the "grid". If you don't know where the data came from, find out.

Is the point "a chart" or is it EXCEL charts in particular. If it's Excel, tag it as such, because there are better ways to work with c# and "charts".

By leaving variables as "var", you leave everyone else to guess what their "real" types are. Too much effort on someone else's part.

Probably simpler if you use "StartsWith" or "EndsWith". But I question the whole approach and point of checking characters in a 2 character state code that has zero significance other than to point to a state name.

"Query literals"? While loops? "Start" by figuring out how to eliminate those.

You have no point of reference regarding performance. You should write a single "Access query" that recalcs "all" inventories. You might find that single brute force is faster that all the other variations. If not, you can at least tell if you're making any progress.

At the "project level", there are not too many patterns; and should be somewhat obvious if you understand the users' requirements: windows / desktop, web app, console app, library, ...

"tried a bunch of variations" ... and what? Nothing wrong with creating and using a "BasePage" and inheriting from that if it meets your needs. CRUD is CRUD and usually follows the same pattern over and over for a given app.

You're using "BigDecimal" where most would use float or double; and that's why your asserts are failing (comparing different data types; inconsistent rounding).

You've shown "one statement" that relates to your heading: ItemSource = xxx.

Everything else, is useless from a problem solving point of view.

If you're "looping and inserting" (an unrealistic exercise) you should be doing a "begin update ... end update" action if you don't want to see "flickering" (a completely predictable result based on what you're doing).

Both your "ifs" are the same; you're showing both classes at the same time: " ... video with image icon underneath ...". You need to hide one or the other.

You delete the record in the database; if it succeeds, you update the grid; otherwise, you have to revert the grid if the database call fails.

The short answer is that Person is part of your "model"; and your model should have it's own namespace / dll; in order to avoid "cycles"; which is what you're experiencing. This applies generally to all common / shared code.

How many records are we talking about? Show them in a list type control if it's only a few. Otherwise, you need to run asynch queries using a concurrent queue that your keypress event can reference.

The Segoe UI Symbol font includes "box" and "line" drawing characters. In the absence of any useful info about how you're creating your "report", that's the best anybody can do for you.
Gerry Schmitz 21-Jul-22 9:26am View
   
You make reference to the "report viwer"; but you say nothing about the "report" (file) or where it came from. The "report viewer" displays a "report FILE"; nothing more. It's during report "generation" when you typically use features of the report "engine" (e.g. certain "events") to add extras (e.g. comment "text boxes").
Gerry Schmitz 20-Jul-22 9:41am View
   
You didn't check the contents of "bytes available". You don't even display it.

The mouse move event fires repeatedly as the mouse moves; you don't need a timer to find the position "over time". And you can test for mouse button down in the move event, if you need to. You may also want to look into "capturing the mouse" if it helps your "tracking" situation.

You don't add it to the viewer; you'd add it to the report; depending on what that report "engine" supports: images and / or graphics commands.

I'm not aware of any "sample code" that opens a WPF window / dialog in the manner you have shown; e.g. trying to hook up a Closed event handler "after" showing a modal dialogs; among other things.

Create the data table; then think about the bulk copy; you've got the two mixed together, confusing the whole extract and translate process. That's why it's called ETL.

If this has a "user interface" (as part of an app), you don't need to keep looping if you have a "Weigh" button / function that the user can invoke when he is ready. There's things like "scale in motion", "centering", etc. you have to deal with and it gets a lot harder when you don't know "when" it's important.

"Term" is an abstract class; you need to determine what "derived" class you are / should be working with; if at all.

F1 is usually reserved for "Help" (screens); ctrl-F4 is used for closing the current window; and "opening" a form depends on the context: e.g. popping a form on the selected row of a grid (say, F2 - edit).

You need a printer that can connect to the "same wireless network". But that doesn't help if you're "out of range" (i.e. remote printing); then you're back to using a proxy / server (over the internet / data service / mobile service).

You're welcome!

P.S. I'm not "against" MVVM, but most can't explain why they're using it, while struggling to stay "within the rules". It's about separation of concerns; but that's only relevant if you expect to "swap out" user interfaces; i.e. views. Most apps don't have "multiple personalities" that justify the "at all costs" effort. And plumbing is not the same as business rules; it's like saying you can only use blue cables.

The foreach "within" foreach doesn't makes sense; in the present context, the second foreach should come after the first. And to "concatenate" to .Text, use "+=", not just "=".

If designed properly, you would serialize / deserialize the view model (class). Serializing individual properties still implies a "settings class" simply for the sake of efficiency and sanity.

"Tables" per se are not application specific. By default, you're creating something that anybody that wants to locks a table should be able to use. The question is, who's going to use it? "Table locks" are one of the worst "sharing" strategies. One "locks" a document, period, etc.; one is rarely justified in locking a table.

Since you admit to not understanding the components you are working with, most suggestions probably won't make any sense. Accept the fact that you will probably need to spend a few days to a week studying (and understanding) the "current" environment before being able to design a "new" environment.

Don't use a MessageBox; it's "modal". Display your message in a text field; in the same window or a different (non-modal) window. Apps often use "status bar" at the bottom of a window for "info" type messages.

There should be a "wrap / no wrap" property. Or you need to trim the text to fit the box. And since it shows "2 lines" when you only want one, it implies the text box is too high also. Also, some users / jokers like to add extra carriage returns, etc. so you need to screen for that.

Group the "values" by value so you wind up with a "distinct" list of values.

Then for each "test", compare the "distinct" list with the "test values". Any "distinct value" not in values for a give test is therefore "not a common value".

"Buffer" (or queue) the data received and use a separate thread to determine when you have "complete" cycle. Add timestamps as you receive data if it helps to figure out a "cycle".

"SelectedIndex" is probably not as predictable as you're expecting. Also, tabs "load and unload" as you select / deselect; adding to the mix.

Generally, "adding" controls in debug mode is less effective than simply making property changes. The more extensive the changes, the less chance the "real time" compiler has of figuring things out (it seems). Code behind usually accepts more changes while running; up to a point.

I have yet to find a practical reason to use a "while loop" to update a UI. From 40 ms to 6 seconds, all my "interval based" apps use a DispatcherTimer to update controls on other threads at a given rate. BTW, users don't perceive lag until you get to 100 ms.
