View 3 RepliesI have a comboBox that is populated with a dataset. The values are:
KG - Kilograms
LB - Pounds
and so on.
So when the user clicks the comboBox in the DropDown the user will see:
KG - Kilograms
LB - Pounds
and so on.

Ok, so I have a listview on one form, and when a button is pressed it opens up a new form with the contents of the selected listview item and it's subitems in a series of textboxes. The user can then change the data in the textboxes and either press save to make the changes or cancel to close the window. What command would I use to change the selected listview item and subitems to whatever is in the boxes?
this is the code that populates the boxes:
Private Sub Form_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim appeditcontents As String = main.passlist.SelectedItems(0).ToString
[Code]....
I have used the command:
For Each Proc as process in process.getprocesses
Combobox1.Items.Add(Proc.MainWindowTitle)
to populate a combo box with the list of current process windows, however for every process that doesnt have a main window title there is a blank space, is there a way that I could tell it to not insert the item if it's mainwindowtitle field is blank?

i have a combobox containing countries name and their codes like INDIA:CNT001 then i have a textbox that store the code of country i.e CNT001(fetching from database) Now i want to match that code with the combobox code so that the combobox is set to that item when i click a button. i m using vb.net and sql server as database.
View 5 Repliesmy program downloads into a combobox every item(line) that is in a text file located on a server.
Every line in the text file ends with "a)" or with "g)".
Now I just want to make 3 radio buttons:
- one that will allow the download in the combobox only the item ending with "g)"
- one that will allow the download in the combobox only the item ending with "a)"
- one that will allow the download in the combobox of both (I already know how to do).
How can I do so?
To download the entire list in the combobox I do:
Dim List As String = client.DownloadString("http://mywebsite.com/mytextfile.txt)Dim lines As String() = List.Split(New String() {ControlChars.CrLf}, StringSplitOptions.RemoveEmptyEntries)ComboBox1.Items.Clear()
ComboBox1.Items.AddRange(lines)
I am new to vb.net and I am using visual studio 2010. I have two comboboxes on a form, each combobox is set to DropDownList so that a list of items can show in the combobox, but no text is allowed to be entered.
For combobox A, if user chooses item 1, the list of combobox B should be updated accordingly. I think this is quite common on a lot of applications. But I do not know to implement it. I even do not know the keyword to search for the relevant property or event handler.

So if you take a look at A cheat engine Video at you tube you can see the checked listbox that you can freeze things and change values so more thann 1 data.
I am using vb 2005. I have items in a Listbox. I want to rename a highlighted(selected) item just like same way the Window Explorer. (clicking the highlighted item, then the highlight is gone and the item string is put into rectangle box and ready for type-in by user.)
View 2 RepliesSo, I need to be able to edit an item that has been selected in a listbox. I need to do so with a button click event. Theoretically, I know how to do this, because I know how to add an item, and how to remove one, and how to insert an item at a specific location.
'Dim strinput As String
'Dim Item As Object
'Dim index As Integer = lstList.Items.IndexOf(item)
'strinput = InputBox("Edit This Item")
'lstList.Items.RemoveAt(lstList.SelectedItem)
'lstList.Items.Insert(index, strinput)
however, this does not work at all. what am I doing wrong??

i got no clue how to edit ListBox items with an NumericUpDown Tool I need to change the selected item in the listbox example->
"7226218; Hemlock; 22.55; 0"
Into -> "7226218; Hemlock; 22.55; *numeric box value*"
After the Add to orderlist button is clicked. It has to replace the old ListBox item and it needs to be saved on a TextBox (the order editor) on form2.
- And order of 0 items may not be accepted
- When nothing is selected, and user presses the "Add to orderlist" button, the program must not be exited with a crash.
- The order (orders.txt) must not be made at start-up, but when the first order is placed.
- When a order has been made, the only way to correct the number is to edit the order.
- When an order is placed, it must directly be put in orders.txt.
- The order must exist after the program has quit.
- You cant order the same thing two times.
- When u type a number by hand, the button to order must be usable.
- The can only change the order amount in the edit program.
My uncompleted code:
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
ListBox1.Items.Add("7226218; Hemlock; 22.55; 0")

I'm inheriting a couple of the common WinForms controls and then manually repainting them so that they will correctly render over a WinForm with the Aero Glass effect enabled. I have this working well with the TextBox. I ran into a snag with the ComboBox though in that it would only repaint some of the control. I fired up MS Spy++ and saw that the ComboBox has an Edit control in it (that's not in it's control collection). I can repaint that Edit box, but I need to get the handle of it and a couple of my attempts have flopped. I found some code that used the FindWindowEx API passing the Comboboxes handle but for me it returns 0.
hwndEdit = FindWindowEx(Combo1.hwnd, 0&, vbNullString, vbNullString)
Basically, I need the handle of the edit control inside the combobox (once I understand how to correct get that then I can get the additional controls in other ones I want like the ListView). Here's the Spy++ screen shots to illustrate (from Spy++ I can see the individual handles).
Is there a way to disable the user's ability to edit the text in the combo-box, so that they can ONLY choose from the options in the drop-down list?

I am trying to use the combobox to update/edit/view the saved data (in contact form) from sql server.
My Load_Combobox (in contact form):
Private Sub Load_Combobox()
'Type
cboType.Items.Add("Director")
cboType.Items.Add("Principal")
cboType.Items.Add("Project Manager")
cboType.Items.Add("Technical Manager")

The problem now is when I saved a record into sql server (EG Technical Manager) and try to view back the saved data, it always show the first item (Director) in combobox. But, my sql server has saved is "Technical Manager" for that saved record.
I have an editable ComboBox with a validation on the Text property to make sure manually entered info is valid.EDIT: All I want to do is populate the .Text property with the ValueMember of a selection rather than the DisplayMember I also have the .Items populated with valid entries having the DisplayMember and ValueMember set.My DisplayMember is a caption along with the data, and the ValueMember is the data itself.So Items might be:
(DisplayMember, ValueMember)
"Foo - 1ab2" , "1ab2"
"Bar - 3cd4" , "3cd4"
I had a validation on the text which can also validate manual user input like "5ef6" The problem I'm having is that if the user selects an item from the combobox it populates the text field with the DisplayMember property (ex: "Foo - 1ab2") which will fail validation.I have tried to manually set the .Text property with the SelectedValue or the SelectedItem.Value on each of the three relevant combobox events to no avail.I would like that the .Text of the ComboBox get populated with the .ValueMember of the item when selected rather than the .DisplayMember
EDIT: I cannot validate by trying to extrapolate the value from the caption. I send the Text off to a service to be validated.
void FillMyCombo
{
KeyValuePair<string, string> listValue1 = new KeyValuePair<string, string>("Foo - 1ab2" , "1ab2")
KeyValuePair<string, string> listValue2 = new KeyValuePair<string, string>("Bar - 3cd4" , "3cd4")
[code].....
The user can manually enter something like "5ef6" which will pass validation.But when they select an item from the list, rather than manually entering it, the .Text property gets filled with the caption and not the value ... so it will contain "Foo - 1ab2" and that will fail validation. I cannot change the validation method to "infer" the value from the caption. I have no control over that service. All I'm after is the displayed value EDIT: Say a user selects "Foo - 1ab2" from the dropdown list, I want the text in the box to say "1ab2" EDIT: I have also tried to set the .Text property in code but I can't seem to make it work in any of the ComboBox events. how to programmaticly set the .Text property (and make it commit!) on a selection event they will also answer this question.
I insert DataGridViewComboBoxColumn columns in a DataViewGrid. That works fine.
Now, I want the user to be able to not only select one list item, but to "drilldown" into the list that is behind the combobox, allowing him to edit (insert/delete/update) the list.
I think it would be a good idea to display a ".." button right behind the dropdown button of the combobox. Pushing it leads to a dialog where the list can be maintained.
What I am stumbling upon is:
How would I create such a custom combobox? Is ComboBox (which is the base for the combo box that the combo box column creates as its edit control) open enough to accommodate such an additional button? What would be the container of the tiny buttoon -- the ComboBox descendant? How I would make the grid create and handle such a custom combobox?
I currently try to solve this by subclassing DataGridViewComboBoxColum, using a DataGridViewComboBoxCell descendent in its CellTemplate assignment, and overriding PositionWEditingPanel and PositionEditingControl to manipulate the sizes of the panel and the combobox so I'd have space for the tiny button. Is that the correct way?
Or would I have to create a DataGridViewColumn descendant which creates a Panel containing a DataGridView combobox edit control and the tiny button? How would I make sure the column keeps care of the combo box so it has the correct items etc?
In my form, I have textbox + combobox to enter datas which are saved to ms access. I have search option too. Also i have DataGrid to show the result of the search. What I want now is, 1. To show the search result in the textbox/combox as well (I already am able to make the result show on datagrid)2. When there are multiple result showing on DataGrid, if i click on a particular result on DataGrid, let the textbox/combobox automatically loads the details of the one i clicked.

Normally to add a item to a combobox I just do:
<option value="310">Willmington (310)</option>
But in a vb.net 2008 I am working a windows app to do the same thing, and for the life of me cannot figure out how.This is what I have currently.
While Reader.Read()
frmMain.cboType.Items.Add(Reader("TypeName").ToString)
End While
[code].....
To add just the item, I can use
combobox1.items.add("New Part")
How can I attach a Value (Like an ID) to this item that can then be accessed from
SelectedID = combobox1.SelectedValue
?
How do you add item(s) to the top of a combobox instead of the end?
