I have a code for populate a combobox with the text from a txtfile.[code...]
But i have about 20 comboboxen en i want all of them with this text from the txtfile.
(Every Combobox in the Form).How do i do that ?
1) On one of my forms i have a richtextbox but whenever the programs ads something like richtextbox1.text = richtextbox1.text & "New Entry" The box goes back up to the top and you need to re-scroll down to the bottum. Is there anyway i can have it to always go to the bottum when something is changed instead of reverting back to the top. Because things are added almost every 1-2seconds until it gets to the point where you cant scroll down to read what was said before something new is added and it jumps back to the top.
If you dont know what i mean make a timer of 1 second that ads somethign to the textbox and youll see what im talking about.
2)Or better still is there anyway to get the program to recive new lines from the textbox. Basicly I have a textfile which is read by around 4-8 clients. I want each client to know what its read so it can process the textfile but i dont want it to say add something like ' to the start of every line its read and ignore all ' lines because then the other client will ignore it to. So what im looking for is a sub that will process the textfile and put any previous unread lines (previous unread lines that session [i.e since program restarted]) into a string array like newline(1)

View 3 RepliesI am using a Class_SQL that gets the table, creates the DataAdapter and DataTable.I have a combobox named cboFullname. I can fill the combobox with data from the database, ie: Dim sqlcmdtext As String = "SELECT *, Firstname + ' ' + Surname AS Fullname From Contacts". I can display full records in a datagridview.
I would like to be able to select a name from the combobox and have the record text boxes display the data and be changed with the cbofullname index changed subroutine. Here is my current code to date:

Is there anyway to carry one combo box from one form to another without the use of loops? I'm trying to figure out if it would be easier to represent a comb box in a new form, or if it would be easier to show it in a print preview window....
View 2 RepliesI have a couple of texbox and combobox controls that are bound to a dataset. I can scroll this with the a bindingnavigator. But I want to have the combobox do autocomplete from the dataset. For example, if i type a "D" in the combobox bound to the 'ClientName' column of the 'ClientInfo' table,i want the comcobox to display all (or maybe the top 20) names that start with a "D". If i then type an "E" I would like the list to show all names starting with "De" and so on.
I have tried to bind the 'autocompletesource' of the combobox to the 'ClientName' column, but that did not appear to do anything.I am reasonably experienced with VB .Net, but totally new to database and data centric applications.

Also here is a screenshot of the options I am speaking of
There is a combolistbox that has a list of topics.
Depending on what topic you choose will determine what checklistbox option will appear in the check list box.
What are they doing there to create that option? I was thinking that maybe they created 20 checkedlistboxes and then if the selection of the combolistbox is "THIS" then they set the getfocus to that checkedlistbox but that didn't quite work for me.
I'm new to programming and I'm using vb.net 2010 and I'm stuck with this problem. So here are the details, I have 2 tables in my database, a product table and a category table. In my product table I have product no, product description and category no. In the category table i have category no and category desciption. So this is where Ive been stuck for the entire day, I want my combox(product) to populate based on what is in the combobox(category). For example I have "Chair" in my combobox(category), then what would appear in the combobox(product) would be "sofas", "dining chair" etc.'the part below is where the program will read the category description from my database
Sub fillcomboDesc()
Dim fillcatDesc As MySqlCommand = New MySqlCommand("Select catDesc from category;", connection)

this little program so a user can choose a hotkey and then set that hotkey with a sentence. The aproach I took to using the values in the combobox to set RegisterHotkey works, but I feel like there is a much simpler and less time consuming way. Basically It too about 700 lines of code to set up 10 comboboxesHow would I go about making a global hotkey with NO modifier such as alt or control.
Imports System.Runtime.InteropServices
Public Class HotKeyApp
Public Const MOD_ALT As Integer = &H1 'Alt key
