VS 2008 How do I clear the listbox in Visual Basic?
View 2 Replieshow to make a listbox change the selected item to the next or previous item by using a button... I want to have up/down buttons.
View 2 Repliesso basically, (pretty simple) I have this listbox, filled with items like
(eg.)
Billy Bob
Jerry
Jo-Shmo
Okay, how can I 'search' and listbox item containing 'Bob', like I click a button on a form with the listbox presented, and then it auto-selects the one that contains bob? HOW COULD I DO THAT?
I've small project to do and now I'm stuck in middle. The program is to read the sequential text file and load it into a array/array of structure.The data information is like this (sample):
ID | Name | Type
1 | Cat | Animal
2 | Dog | Animal
[code]....
This is Just as sample data, my original data is more than this.I've open the DATA.txt file using FileStreamReader:
Dim FileStreamReader As StreamReader = New StreamREader(DATA.txt)
Read all the elements in the list and pass through ReadArrayString.Split the string using:
DataString.Split(New Char() {";"c})
Pass through
ReadArrayString(0)
ReadArrayString(1)
ReadArrayString(2)
Where index 0 is the ID, index 1 is the name, and index 2 is the Type Then I load the types in the dropdown combobox menu from the array with out duplication. Like this:
If TypeComboBox.FindString(ReadArrayString(2)) < 0 Then
TypeComboBox.Items.Add(ReadArrayString(2))
End If
Now When you click TypeComboBox it will show drop down menu with following list only.
Animal
Bird
Fish
After this, when Animal type is selected/clicked from combobox dropdown menu then it should only add the Id and Name of Animal type in the ListBox.Pseudocode may looks like this:
If Animal is selected/clicked from TypeComboBox then
Add Cat into listbox
Add Dog into listbox
[code]....
I've only figure out load items from only one column/array into combobox with out duplication.But can't figure out to compare the value of one column/array with another column/array and load it into listbox. I don't want to hardcode or write matching value inside the code. What I want is use the Array.
I've got the following txt file:
[code]...
Now I want that presented in the listbox with the semicolon and it should be aligned per column so that the numbers, the names, the prices and the quantity are exactly aligned per column.If I read the file like this:
[code]...
Then the semicolon is not presented in the listbox and I don't have any alignment per column. As the names of the woods are not equally long the prices and the quantity are not aligned directly below each other...
My questions are:
1) How to add the semicolon in the listbox as seperator of the columns
2) How to align the 4 columns in the listbox (as I have an array Item(3) )
Later on I need to be able to change the quantity (last column) from 0 to > 0 (that's why I have to use an array)

View 6 RepliesI am trying to create a DLL from a class library in Visual Basic.
First I created a new Project in Visual Basic Express 2010 as a class library. Then I added a class which contains a function that I want to access in another program. This is why I want to export the class library as a DLL. In visual studio I am compiling the project which refreshes the saved dll in the bin folder of the project directory. When I open this dll or include it as a reference in another executable visual basic project, it does not find the function. how to generate a dll from a visual basic class library properly?
Here is the code of the class stored in the class library project:

However I have hit a massive brick wall with my program. My program that I'm trying (can't emphasis this word the importance of that word) to create a Client/Server chatroom using TCPClient in Visual Basic. So far I can get my client to speak to my server. However, i'm trying to get the returned data to display in a listbox which never happened, i then tried a label, which again never happened then a text box which I'm sure you can figure out how that went! I'm not great at networking programmers nor am I not bad I'm terrible but duty calls when it comes to projects.
The code I currently have was mostly taken from the net but when I have the program fully work and I understand how the software works I intend to heavily modify for it to suit the needs of what I need to achieve. where I can get my client to display the data from the server that I have already sent to the server (which displays successfully within the server).
