i have an app that has many suggest append comboboxes in the style of just straight dropdown.
I also clear the text in all of these draopdowns via resettext() in a loop when my user clicks a 'New' button
is there any way to either A:
make the combobox read only (without selecting dropdownlist)
or B:
allow suggest append to fire on all keystrokes instead of only when it sees a match in the combobox....
example: combobox1 contains the following items:
- apples
- oranges
- bananas
as of right now, if my user types in "pears" it won't see any 'P' and won't suggest anything else or even drop down the combobox and allow "Pears" to be entered and because my app does processing only on the items in the list, "pears" then throws an exception....I'm trying to force them to choose only the items in the list and not be allowed to enter anything else while still enjoying the clean look of a resettext() on a combobox

[Code]...
This is a really basic question. This code currently sets the dropdownlist like I want, but just doesn't return selected month and year. How can I fix this?Note that Main2 sub is for PostBack = True.

I have a DataGridViewComboBoxColumn, and want to switch the style of the ComboBox control between DropDownList and DropDown (mainly for the text field editing capability). I'd like to do this on a row-by-row basis (at the DataGridViewComboBoxCell level).How would I do that programatically? Or maybe a different way of asking: How do I access the ComboBox control given an object of type DataGridViewComboBoxCell?

Is there any way of making controls that aren't textboxes into readonly controls? Specifically I have a date time picker (but I have the problem occasionally with other controls), that I want to make ReadOnly as opposed to disabled so that the user can see clearly what is in the control but cannot edit it. Making a control like this disabled makes it hard to read and furthermore, gives the impression to the user that they are to ignore the field, which defeats the object.
I'm sure a suggestion will also be to stick the information into a text box, however there are other date time picker controls that CAN be edited in the same window, and it would make life a lot easier if the layout of each was exactly the same.

I am using a PropertyGrid control to edit my class properties and I am trying to set certain properties read-only depending on other property settings.This is the code of my class:
Imports System.ComponentModel
Imports System.Reflection
Public Class PropertyClass[code].....
This is the code I am using to edit the values:
Dim c As New PropertyClass
PropertyGrid1.SelectedObject = c
The problem is that when I set SomeProperty to True, nothing happens and when I then set it to False again it sets all properties Read-Only.

How can I make dropdownlist no postback - I have a dropdownlist which I put a code in selected indexchanged - basically for every indexchanged the code will connect to sql and get values then populate textboxes with values.
Here is my code
<asp:DropDownList ID="ddlSalesOrg" runat="server" Style="width: 200px;"
AutoPostBack="true" />
Obviously when I remove the autopostback="true" - then indexchanged will not function as expected.

I have placed several PictureBox Images of different colored dots(which represent lights) on an image of a Christmas Tree. I can make the lights randomly flash using a randomGenerator and a Select case statement. However, the code is very long. There are 67 lights on this tree and the code is 71 pages long. There has to be an easier way to do this. So far I have tried the following with two images of lights just to see if it would work and it does not work:
Dim picLight(2) As
Boolean
For intX

I've got a datetimepicker control on a vb .net 2008 form. I have set it to show a custom format of "dd/MM/yyyy". The problem is this: - when i click on the arrow button, a small calendar is shown in which i should be able to select a date. The only way i can do that is by using the arrow keys and pressing Enter. Clicking on any date value inside this calendar doesn't do anything.How can i make the value of the datetimepicker change to what i have clicked inside the dropdown calendar?
