I want my listbox to not display duplicate items. I just want it to update the quantity(Qty).
I am using VB.NET (version 2008). I have two types of items populating in a listbox (checked listbox). For example: lets say one is type "A" and other is "Type B". Their names maybe same so if the user sees those items in listbox then he won;t be able to determine their type until he click on them and checks out its properties. I wanted that I add each item to listbox and colour them so that blue for example means type "A" is there and red means the other. So this way I will be able to know at a glance that how many item of what type is present. I guess it may not be possible to do that in a standard checkedlistbox. I am also using component factory's krypton controls which enhance the gui of an application. But I dunno if I can progress using that.
View 5 RepliesI'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.
probs a simple answer but my mind is blank atm. I have this code to move all items from listbox3 to listbox1 but it wont move them unless i select 1, then it moves all items.

I'm using Visual Basic Express 2008 to create an interface with a order database in MS Access 2007 (.accdb file). Everything is fully functional except updating the "Inventory" table is very slow. Updating around 2200 items takes almost 2 minutes and the window will appear as "not responding" for the duration if you click away and come back. Here is the process:1. Tab-delimited text file is picked by user, which includes all inventory items (not just new ones)2. Each line from text is parsed and read into variables (tempSKU, tempItemTitle, etc.)3. Old items are updated and new ones are added. -> This is the bottleneck
I used to have a series of IF statements to check which elements were changed and report them, but that was about 2x as slow. The new code is a little faster but doesn't provide the feedback I liked (update part is commented around):
Private Sub btnImportInv_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) andles btnImportInv.Click
Dim strName As String
[code]....
But I've got a problem now, and I haven't been able to find any answer. Here is the code I'm executing:
Imports MySql.Data.MySqlClient
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick

The meaning of this code is that if the file exists, it will add a new line called Success below the dragged fileline. If the file doesn't exist it will create a new line called Fail below the dragged fileline.

lstCommandLine is another one of the listboxes. i need to get the index of the lstStatus item that the loop is working on now which i will store in i. ill need to change the listview subitem from ready to complete and the lstStatus item from ready to complete as well. im guessing that would be in the same loop.

View 18 RepliesReading through "The Pragmatic Programmer", I've come across the DRY (Don't Repeat Yourself) and Orthagonal (keep code modular) principles.I have a suite of modules, some of which have common procedures. Because each module is a separate project in Visual Studio, up until now I have simply copied code from one project to another when 1 module (project) needs to do the same function as another module (project). This is when functionality overlaps, not when 2 modules (projects) do everything the same.
I always suspected this was bad practice (and have seen the fruits of my suspicions when the subs get out of sync), and the book confirmed me in this belief. So, what I want to do is make a central code repository for the 4 or 5 common subs, but I don't know how to do it.Should I make a .dll file for each sub I want to use in multiple places? If so, how do I do that? Is there another way to do what I want to do?
1. I have a subroutine that takes a filepath (and if disconnected also a SqlConnection) and loads the referenced file into a database as a BLOB.
2. I have 3 separate projects in 1 VS solution that all run basically the same version of this code.
3. I want all 3 to run EXACTLY the same code.
4. I want 1 version of this code so that any changes made don't need to be made in 3 places.
5. I have a few other instances like this for other subroutines.
For example:
test is a variable
test = 1
How do I make that if test = 1 that a listbox fills with the items: red, blue, green, yellow?
If test = 1 Then
listbox1....

I have a listbox that gets populated with files paths based on search terms provided by the user. I want the user to be able to select multiple items on the listbox, and then be able to export the files listed to another folder. See the attached image for what I'm talking about.
The problem I'm having is that I don't know how to take the items selected and turn them into a string array. Everything else I can figure out, but this one has me stumped.
