I'm having kind of a hard time about this, just would like to ask if anyone knows how to check if a string that is input by the user in a text of combo box is in the list of the combo box?

I am trying to check if a users input contains any special characters from a list, does anyone know who I would go about doing this?
I've tried the LIKE operator:
Dim sMatch As Boolean = tTitle.Text Like "[-/,.:;*?""""<>|&'[]^%£$()_+=!#]"
but doesn't seem to work, i think special characters are used for settings.
Is there a RegEx i could use for this??
How would I check a given string for the presence of any match with a character listed in another string. I'm just looking for a binary result.
In other words, how would I write the VB.NET function called IsPresent in the following code snippet?
Result = IsPresent(AnyString, MyTestString)
For example, if MyTestString = "XYZ" then I want the following results for the given AnyString values:
MUTTON, Result = No
BUZZ, Result = Yes
HAPPY, Result = Yes
FISH, Result = No
I want to know if a string exists in the list of array ignoring case sensitivity
I have the following code working for my requirement, but its checking case sensitivity. How can use it ignoring case sensitivity...?
Dim SrtList() As String = {"abc","qwe","zxc"}
Dim chkStr As String = "abc"
If strList.contains(chkStr) Then
[Code]....
I want the Function to accept List(Of String), Array & String and similarly return List(Of String), Array & String respectively. The Function simply adds a string (month) to the input collection. I just want to use it for string, array and list with needing to think of conversions.

A couple of questions about check list boxes:
How to check/decheck all the item in the list How do you copy or delete all checked items in the list
I got an object of List<List<string>>I need to bring this into a ist<string>I have no idea how to do this with LINQ.
View 1 Replieshow to say it. Im going to be making a program for my work, something for our CNC programmers to use for referencing machine code. Basically what i want is to have 2 combo boxes. One of them will have some letters, the other will have some numbers. If the user selects "X" in the one combo box and "54" in the other combo box, i want a label that will output "5221". The output is a given number, it will never change. Everytime that combination of of combo boxes have those things selected it will output "5221". So now my question is what is the best way to do this? My first instinct was a select case. Is this the best way to do it? I was also thinking about possibly using textboxes and having the user manually enter values instead of a combo box with some 60 numbers in it. I marked this as a discussion also, thinking it is more of a discussion than a question.
View 8 RepliesI this application, I am retirving data to fill combo box from database.There is a search buttom next to it which takes that selected and search in database and retieve other data related to it.Now in the combo box, one can also enter data (textfield too).So if the person enters wrong things, I want to display a message that " Incorrect value"
My code for the onclick_search is as follows:
Private Sub btn_cylsearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn_cylsearch.Click

Is it possible to have a Radio button list, like we have a checked List box?Actually I want to load all the options from database to the list but do not want user to allow to check more than one item.
Also how to read it (say item 4 of the list) I want to store its value in the variable.
I am trying to create a WPF browser application that allows you to search and display recipes. The combo box presents choices, the Ingredients display in one list box and the "cooking" instructions appear in the other list box. What's happening is the first time you make a selection from the combobox nothing displays, and this could be happening because the first line of code under Selectionchanged clears the List Boxes however, it should be populating those list boxes with content, shouldn't it? Anyway, as you make other selections List boxes 1 & 2 get populated but they do not match what displays in the Combo box, i.e. if you select "Easy Taco Dip" any random recipe might appear in List Boxes 1 & 2.

Basically I need to create a form that will display a summary of the population trend for each species of butterfly from a database that I have.I will do this by having the user select which butterfly species he/she wants to view from a combo box and then the list box will display the count_2010 and count_2011 information for that butterfly species.
I have managed to link my combo box to the database but I am unable to get any information to be shown in my list box. I can use a select case and input text myself but I don't want to do that as in another form records need to be added. Is it possible to have the relevant fields from the access database show up in the list box after the user selects a species from the combo box?

View 1 RepliesI have a project that currently uses an XML config file to create some groups. Based on these groups, you can search a database for information. What I want to do is create a form for editing that file. I can get to the information via messagebox, but when putting it into a ComboBox, I can't get the list updated. I have tried the text property which only populates the initial selection, and the Items is a read-only property. Nothing else looks close to what I want to do.
My other thought is to populate a datatable with the information and then populate the combo box from the database. It seems like an extra step that I shouldn't need, but it may be the only option right now.
The reason it can't be hardcoded is that the XML config file is already being used by a program, and the file may be updated from two or three computers, meaning I need a central location for the file.
I have a ComboBox with around 50 google search engines world wide list that looks like tihs

The combobox is bound via binding source to a table. How can I display the list of look up options while having the first option say [None} and if selected, clears the value from the list.
View 2 RepliesOk what I have is a combo box with a set of default items but i want the user to be able add new items to the combo box's item list. i currently have a text box and a command button for the user to use to add new items to the list with this code attached
ComboBox1.Items.Add(TextBox1.Text)
when the program is closed the item is no longer in the combo box items list.
so what i would like to know is the correct code to make the additions to the combo box's items list permanent or at least until the user chooses to remove them.
I have 3 combo boxes on a form. They are all going to load the same list. This list is in a database. My first thought was to attach the list to the combo boxes as a datasource. That would require me to create the datasource 3 times to load the same list. To me that seems terribly inefficient. If I attach all 3 combo boxes to the same datasource (list object) then when one cboBox value changes, they all change. So my thought is to load the list once into a list object, then create a loop that loops through each item in the list and adds it to the 3 combo boxes.

View 5 RepliesI need to be able to check from code whether the SuggestAppend List (not sure if that's it's proper name, I mean the dropdown that appears when you start typing into a combo whose auto-complete mode has been set to Sugest Append) is currently showing. Basically I'm looking for something similar to the DroppedDown property but applying to the SuggestAppend List rather than the Drop Down. Can anyone tell me what property I should be looking at?
The reason I need this is I need to do some work when a user cancels an edit in the combo by pressing escape. I've trapped the escape keypress but this only represents an edit cancellation if the dropdown list and the suggest append list aren't currently showing (otherwise the escape just closes the list).
I have a combo which contains a lot of different colours. If I press b it goes to the b's in the list and if I press it again it goes to the next b. Is it possible to jump to the colour as I type it so if I type blu it would go to blue. Currently it jumps to the first b when I type b but ignores the lu for blue.
View 4 RepliesI have been using the combo Box keypress event to capture the enter key when it is being pressed by the user within the combobox. The combo box style I am using is Drop Down. When there are no items in the combo box list the keypress event will capture the enter key. When I add any items to the list portion of the combo box the keypress event not longer captures the enter key. How do I capture the enter key when the combo box has items in its list.
