Change The Item Value Or Text Of Combobox Control At Run Time?
May 15, 2012
What I to do is really simple. I want to add a group of text boxes in my VB net application. note that the number of text box only can be known at run time.
I want to give default value to this group of text boxes. At run time, users can input text and change the text for each item.
How can I do this? Is there a control to do this?
What I can remember is ComboBox control. However, I only can display the item text and do not know how to change the text for each item.

Just started on vb.net
I have a combo box with "yes" and "no" with i select Yes i want the label2 to change the text to "yes" likewise with "no"
I've tried to code it in a logical way as possible but it just doesn't works except for the "wtf" so i think that overall my code is correct but the way i want to retrieve the selected item from combo box is wrong.
Public Class Form1
Dim aa As String
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As

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.

I have a combobox called cbMaterialType on a windows form that's bound to a table in SQL - everything loads great and the combobox displays 'Material' items as it should, in that table I have two fields - Material (as mentioned above) which is a char(25) and InStock which is an nchar(1). If the InStock field contains a '1', I'd like the individual material to be green in the combobox, if '0', then red. I have the simple code in the drawitem event of the combobox as follows, but can't seem to get any results at all:
Private Sub cbMaterialType_DrawItem(ByVal sender As Object, ByVal e As System.Windows.Forms.DrawItemEventArgs) Handles cbMaterialType.DrawItem
If MaterialTableAdapter1.GetData.Item(cbMaterialType.SelectedIndex).InStock = 1 Then
cbMaterialType.ForeColor = System.Drawing.Color.Green
Else
cbMaterialType.ForeColor = System.Drawing.Color.Red
End If
End Sub
I've never worked with any form of color in comboboxes before and this is my first attempt at the drawitem event.

the below statment is right 100% but what i need is to change the word mobinil when the user choose another item from the combobox
cmd.CommandText = "select * from warehouse where mobinil ='" + ComboBox2.Text + "'".I thought that i can do the follwoing dim x as string x= here will be the item selected by user- and ofcourse i need it to be put instead of the word Mobinil
cmd.CommandText =
"select * from warehouse where x value ='" + ComboBox2.Text + "'" is that possible ?

I have a tab control application, each tab loads a particular user control and each of those user controls will then add other user controls that are used amongst other the user controls. For example, I have an "ucQuotes" page and an "ucInventory" page, when the specific tab is selected, the "uc****" user control is loaded on that page, and in the case of "ucQuotes" and "ucInventory" they both use a control called "ucPartNumber"; a user control consisting of a combobox, textbox, and button. I have no issues reusing the shared user controls, in this case. My problem arises with my "ucQuickPrice" control, as it is always present at the bottom of the tab control form (separate from the tabcontrol, but on the same form), and it too uses ucPartnumber.
Here's my issue, as I type into the ucPartnumber combobox, the text I type does not appear in the combobox, it appears in the textbox of the ucPartnumber control that is being used on the tabcontrol page. There are no shared instances of ucPartNumber, nor do I have this issue between typing on one tab page and the text showing on the user control of another tab page.I tried just creating the ucPartNumber controls on the ucQuickPrice control, not adding a new instance of ucPartnumber on the .Load event, and the issue persists.
The combobox(s) in question are bound programmatically with about 40,000 items, ".datasource = dataset.tablename" not to a bindingsource. Autocomplete is set to none, I added code to utilize tool tips and the basic combobox filtering functionality. Is this a bug, or is there something I'm neglecting? I'm about 95% complete with this application, and this just happened today. I made the decision, to just reuse the ucPartNumber control on the ucQuickPrice control (originallly it's size and orientation would not fit, but I added some coding to detect what parent is adding ucPartNumber and to change its appearance accordingly). Before, I made this change, I did not have this problem. And, in trying to go back to how I had things set up before the change, the problem will not go away. if the whole control within a control verbage I used is a bit confusing, let me know and I'll try to better explain what is happening. At this point, I'm going to close and reopen vbexpress, as when I started this ordeal, vb started acting weird and wanted me to save all my work, it usually does this before locking up.

Just getting started in VB.NET. I would like to add X-number of text boxes at run time. And then be able to address them by their index or some sequential numerical value (like an array)
This is what I have so far:
CODE:
When I turn this into a loop to create multiple toolboxes, how do I assign a name to the controls, or will all of them be named "MyTextBox" ? I'll increment their position so thats no problem.

The form has 2 ComboBox and 1 NumericUpDown controls. I would like to change value of NumericUpDown based on selection in ComboBox. For example:
ComboBox1 has three value. for instance, AAA, BBB, CCC
ComboBox2 has three value. for instance, DDD, EEE, FFF
The NumericUpDown should has range 0-6 sum of both ComboBox. For instance, if user select from ComboBox1 AAA and from ComboBox2 EEE the NumericUpDown should display value 5.

I have a problem with combobox. I set the DrawMode into OwnerDrawVariable so I can draw items seperately with styles, but the characters of the items are now displaying blocks. The block characters are none ASCII. It used to display well but not now and I don't know what caused it to happen. I didn't change my system locale. At the same time, other combobox that have Normal DrawMode displays nicely fine.
My custom drawing code:
e.Graphics.DrawString(combo.Items(e.Index), combo.Font, b2, rect.X, rect.Y)

I have written a code in VB.NET using "Microsoft Outlook 11.0 Object Library" to create an appointment, task or contact in Outlook. Now the problem is once i create an appointment, task or contact from my VB.NET code and then if i open these item in outlook and modifies and save the content (like body of an appointment) then the lastmodification time of these item doesn't gets modified. It always shows the previous lastmodification time. This happens only for those item which got created from my VB.NET code.
I have tried realsing the COM object in my VB.NET Code.

In my never ending search for more knowledge, I have come across Partial Classes. I was wondering if some of the kind people who actually understand the uses could explain some of them to me. Now I know that when we create a form that we actually create a partial class which the generator rewrites when we add a control or change a property at design-time, and this allows us not to have to worry about setting up the controls ourselves.

2) How to make the RTB's Back Color to transparent??? Cause it is not supported. Or is it I use the wrong control???
