Identify Subtriangle Within A Rectangle Given A Coordinate In That Rectangle?

Feb 22, 2010

Given a rectangle of width w and height h. and a coordinate x,y in that rectangle I would like to identify which triangle I am within.

i.e. the function should take parameters(x,y) and return a,b,c,d or a zero based number representing that triangle index i.e. (0=A,1=B,2=C,3=D) if they are in that order.

I think this would be something like >= the formula of the red line and >= the formula of the green line?

I'd like to implement this in VB.NET

Width Of The Auto-dropdown Box Not Match The Width Of The Combobox?

Feb 6, 2011

In VB.NET for the combo box, I have set the autocomplete mode to "SuggestAppend" and autocomplete source to "ListItems". Its working as expected. But the width of the autosuggest dropdown box is not same as that of combo box and so it looks weird.I tried changing the value dropdown width property but it changes the value of normal dropdown box (seen after clicking down arrow on combobox), and not the autosuggest dropdown box.So what code or property needs to be set to make autosuggest dropdown box the same width as that of combobox width?

Printed Line Width Too Wide Even When Pen Width Is 1?

Mar 18, 2010

I have a drawing program written in VB6 that is capable of printing very thin lines to a laser printer. In VB .net, even though the pen width is set to 1, the thinnest lines are way too "thick". The equivalent line width in VB .net using a pen width of 1 is about the same as the DrawWidth = 4 in VB6. So, my question is, how can I print very thin lines to a laser printer in VB .net?

UI-threading An Easy Way To Fix It?

Jan 23, 2012

I am communicating with a USB-HID device. It will successfully complete hundreds of send-receive requests but occasionally get a Null Exception error.

[Code]...

at the rxData.dataPacket(i) = element I will get a NullReference error every now and then. I could enclose it in a try/catch statement, but I'd like to fix the root problem if possible.This device is communicating to microcontrollers, and it is possible that they won't always give a value... but my feeling is this is some sort of UI threading issue. When debugging, even though there is a null exception, many times there actually does seem to be data in dataReceived.data.ToList(). Is there an easy way to place the whole data processing routine on a thread separate from the UI?Edit: Changed code to match answer and give more info on where it is used. Still get NullReferenceExceptions after about 1,000 completed send/receive requests to the HID device.

.net - VB Flamed For Being Easy And Yet Python Is Not?

Sep 19, 2010

I have always wondered about this and seen this among lots of programmers. Why is a VB programmer or VB code easily dismissed as too noobish and easy while the same does not apply to Python or Python code? After all, isn't Python as easy as VB is? And it does provide drag-n-drop GUI application building also. So why is it that VB is flamed and yet Python is not?

An 'easy' Way To Capture Video?

Apr 15, 2012

I've been trying to play with DirectShow but it's getting on top of me and my question on here didn't answered so I'm thinking maybe I should go with a different approach. (DirectShow VB.net can't change recording format). <- Where as that 'works' I can't get it in the format I want it, and I don't really understand it so I'd obviousl like to go down the route of something I can get my head around.

I've googled till my fingers are raw trying to come up with an easy way to record video in my vb.net application, it doesn't have to be fancy, just a preview with a start record, stop record button, that's it.

Easy Way To Iterate Through Objects?

Jun 25, 2009

Lets say I have 30 text fields in a Frame on my form, and I want to set them all to disable (so users can't edit them).Is there an easy way to walk through those fields without having to create an array of text fields?

I.E., in ... VB 6, with an array of text fields, I can do something like this:
For i = 0 to 10
txtfield(x).enabled = true.
Next i

Is there something in VB.NET where I won't have to use an array of controls, something like this (assuming all txt fields are in a frame):

Easy Way To Detect Internet Connectivity?

Oct 28, 2009

I saw another forum which discussed how to detect whether a LAN was connected, but I need to know whether my Internet connection from my ISP is up or not (I'm writing a program for day trading, so knowing if my internet connection is down is critical). I know I can simply open a browser in VB and browse to a site and see if it doesn't come back "page not found", but that involves a fair amount of overhead, and if the internet is down, it often takes many seconds to a minute to come back with "page not found". Is there some simple command that will quickly tell me that my internet connection is working? I'm using VB in VS 2008, and currently using XP although I plan to convert to Windows 7 in the next couple months.

Easy Way To Wait For Keypress From User

Jul 30, 2009

I want to have a one second pause after some code has run. During that pause, if a certain key is pressed, I want to do some action. Otherwise, I want the code to continue as normal. What would I use to replace the comments in the following code?

myTestCode()
' Wait one second and see if a given key was pressed.
' If specific key is pressed, then show messagebox (or whatever) asking user if we should cancel (whatever)
NextMethodToRun()

Yes, I know there are a number of ways, which is why I am looking for something that is fast and simple to use. I do not want a console window, some other form, etc. to appear. Just want to check if a key was pressed. The key (if pressed) should be pulled off the keyboard buffer.
