• cehor Hex values in textbox to send out serial com1 using an array.

  I am trying to write an application that sends serial data out com1. The data is entered in to a 'textbox' then you press the send button. An example would be send: 1f ff af 01 55 // These are all hex values. I have a string of hex values to send out the port to turn on a LCD projector but I want the ability to change the string, that is the reason for the textbox. I can setup an array and load the values manually then compile but like I said I want to be able to edit. My problem is with the array load. The method I am using is: byte [] myArray = { byte .Parse(textBox4.Text, NumberStyles .HexNumber) }; This will load the first byte but I can't load any other data or I get a format error. I need to be able to load e ...Show All

• Jan Kučera problem adding menu items

  heres what im trying to do: make it so that a user can supply a name,path, and category for a new dropdown menu item ex: if user puts this into 3 diffrent textboxes : name = bob path = C:/bob.exe category = help and clicks "add item" a dropdown menu item is added to the "help" button on the menu and the name is "bob" and the on_click is "process.start("c:/bob") " i got it to work but when i close the app and re-open it the item is not there, i want it to stay there. thanks in advance, Menu options are not retained automatically.

• William Xie Fill an array from a text file.

  Sir/Madam, I need to fill an array from a text file. My text file looks like this for different people. First Name|Last Name|Address|Phone First Name|Last Name|Address|Phone First Name|Last Name|Address|Phone First Name|Last Name|Address|Phone First Name|Last Name|Address|Phone Do you know of any way to put these into an array from a text file where the "|" symbol seperates the columns Any help would be greatly appreciated! I propose a different route. An array is not a good collection object for information like this. Visual Basic has built-in support for parsing files like yours. Try this: Imports Microsoft.VisualBasic.FileIO Module Module1 Public Structure Perso ...Show All

• flash.tato NumericUpDown Control (ValueChanged event)

  I have an assignment and I am stuck on one thing. A part of the assignment is to make the NumericUpDown and have the value changes in the NumericUpDown control, change the average using the ValueChanged event of the NumericUpDown control. Basically, as the arrows are clicked up or down, the average needs to change automatically. This program is a Grade Average Calculator for testing 3 Grade scores and then testing to get another average after the lowest is dropped. It also displays a letter grade. I am currently using VB Express 2005 and I think it is a great program. A quick response would be greatly appreciated. My code is as follows: Public Class Form1 Private Sub BtnReset_Click( ByVal sender As System.Objec ...Show All

• razerredblue Custom Controls - anyone working with these?

  Firstly, does anyone else think it would be a good idea to have a forum devoted to TFS Custom Controls Secondly, I'm using Naren's excellent article on custom controls to start building an example, but the IWorkItemControl does not have the same interface as mentioned here (so the code sample does not build). He mentions an AfterUpdateDatasource event and there is no mention of the FlushToDatasource method. Has anyone else been building custom controls How have you implemented the FlushToDatasource method Looks like for some people the new dlls are not getting installed, but it seems to work fine for some others. Can you check versions of Microsoft.TeamFoundation.WorkItemTracking.Controls.dll and ...Show All

• JHarjung Check in Now

• William Lowers Windows Form Timer and elapsed event

  In VB.net 2003 I had a piece of code that used a timer. In that code, the timer I dragged onto the form was created as a System.Timers.Timer and had the elapsed method which got fired when the timer.interval had been reached. With VB 2005 Express, the timer control is a System.Windows.Form.timer, which does not have the elapsed control. What I want to do is fire a piece of code when the timer value has been reached. I found a number of examples, but they fire on every tick -- which doesn't do it for me. The code tells the user how long until the next event, (approximately) i.e. next event in 8 minutes 10 seconds.... The old code still works, but I am fixing the design of a number of things so I am more or less starting over. (It i ...Show All
