View 2 RepliesSo I have a program that is supposed to support a small business. I have the work completed and the professor said it was correct but I wanted to go do a little extra.Basically, on the Order screen, you begin to type the name of a customer/supplier/employee into a text box and a list of names that fit the criteria pops up in a list box (lbMatchingAccounts). When you select it, you can hit enter new order and be transported to the Order Details screen to enter the new order.
What I wanted to do was to create a new list box (lbOrderId). What I want is to be able to select a person from lbMatchingAccounts and have all their Orders populate in lbOrderId.

View 2 RepliesI am encountering the following issue So i have a device that sends stuff at the serial port, i then parse it and put it into an array of bytes like that:

Basically what i wanna do is let the port parse the messages, fill in the array with the result at an empty spot in this array and then i will have a separate thread that will look in into this array in each non empty space and after it looks into the non empty space it will use or discard the info and also mark this space as empty (after it checked)
I was just wondering how you can make classes import into your main Form.vb
Let's say I make a class with the following.
Public Class OtherStuff
Public Sub HideMe()
Form1.Hide()
[Code]....
How could I make the Form1.vb include the things that are in OtherStuff.vb.
All of the solutions that I have tried come up with the same error. Reference to a non-shared member requires an object reference.
I made a picture box and imported an image named Title.jpg. Later I made adjustments to the picture and imported it again without deleting the original(mistake). The new one had the name automatically changed to Title1.jpg. So I deleted the original image from resources and renamed Title1.jpg back to Title.jpg.
Now I got two problems. First, only Title.jpg is on the solution explorer, but Title1.jpg(along with Title.jpg) still pops up on the resource list when I click on Image property of the picture box. There's only the name and no picture, and I don't see a delete option. How do I get rid of it? Second, even though I changed the image to the new Title.jpg in the picture box, the old one is displayed when running the app. What's up with that?
In my listbox I get a collection of strings in this format:02406L101G0,967S or 12010C2100,978U. I should get this list on a regulated manner.haracters in the seventh,eighth and ninth place (from left side) always make the numbers eg: 101 or 210. Is there a possibility to edit the list of strings (in listbox or a listview) in accordance with the number obtained as a substring (7, 8 and 9 character)?
View 9 RepliesIf I set a ListBox.Height = ListBox.PreferredHeight when the control is hidden and IntegralHeight = True, then set it visible:
a) Actual Height reduces by typically 3-5 pixels after redraw (but not 1 pixel per item).
b) PreferredHeight does not not appear to give the correct integral of item heights.
Is there a way to make ListBox calculate the correct integral Height before the ListBox is made visible, so it can be correctly pre-positioned from bottom edge?
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
ListBox1.Visible = False
ListBox1.IntegralHeight = True

View 8 RepliesI am currently setting up my own media player and so far there is only one thing that is making me very unhappy/frustrated. I have searched google so much and still couldn't find the solution. Here is my problem. I'm trying to import MP3s into a ListBox and have that as my playlist using this code:
For Each Song As String In Import.FileNames
playlist.items.add(Song)
Next
The only problem with this code is that it displays the song's full path in the list box. What I'm trying to do is just bring in the name of the MP3 without showing the path and still have the song play.

View 2 Repliesi have 2 list boxes.. Qty and Cost both of these are populated from a sql database. The code is suppose to read through the listboxes and multiple the Cost by the Qty and then replace the Cost with the new result. The Cost listbox is populated with the cost of one item. The reason i am not doing this calculation in the sql query is because the sql query is very complicated filter out a bunch of stuff to show just the qty of the item...

1,2,3,4,5,6,7,8,9,10
If he put 20 in first textbox, in second textbox it should be:
1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20
2.I need to do this...Import text file to listbox.Export items in listbox as text file.
im trying to make a program in which if the textbox text and the listbox text are the same order, which they are in the picture, a bluie fonted text saying well done appears. However only the red text appears which is only meant to come when the order of the text in both listbox and textbox isnt the same.
Here is the code that i used for this:
listarrays = name of listbox
textbox1 = name of textbox
l is the name of the label for correct answer(blue font)label3 is name of label with red font which should only appear for wrong answer
Dim text As String = Me.TextBox1.Text
For Each item As Object In listarrays.Items
If item.ToString = Me.TextBox1.Text Then
[code].....
use another textbox instead of the listbox but thats just making itmuch harder for me as I already made the full code working with the listbox. My lecturer told me i need to convert both in string so both textbox and listbox are compatible and i did so (see code above) but the correct label doesn't show?
if you want to make program to calculate the result of brackets math question , as 6+(9+(5-(1+(2+1)))) , and you made 2 buttons representing ")" and "(" , and you want when the user clicks on the "(" button it just applies that the number before it to be stored in a place like a label such that the program calculates numbers after it and then calculate the produced number and the label number , something will disallow you that the questions with many brackets as the mentioned one above 6+(9+(5-(1+(2+1)))) will for example store 6 and plus sign in a label but after that 6 will be placed by 9 because there is another bracket after 9 , so the question will be calculated false , more clarification for my question is the way brackets are made in the windows calculator so i want a coding idea to make the brackets like in the windows calculator
