I have a form with a lot of PictureBoxes. I created an array of these by name, but when I index the array I cant assign an image to the indexed item. In fact all the indexes appear to be nothing. Is there a way to create an array of controls and access them from the array?

Is it possible to select an item in one listbox and then display the data of another listbox with the same indexed position? I am planning a project and this is something I would like to attempt but I haven't figured out how to do it.[code..]
I tried doing the above code but instead of displaying the listbox text the message box just returned false.
I wish to create a drop-down list box with items in it. Easy to do and done that. What I also wish to to is assign a numerical value to each list item. I believe under VB6 is was done using the list's `Value` property to set and get the item. It's so I can write a one byte value to a file but display a text value on the form. Don't wish to mess wish classes and arrays, but if I have to I guess it'll be have to be done.Was looking at some examples of making in-memory arrays/datasets for a list-box but just sees like a programming overkill for the simple thing I wish to do.Put it another way....
List box item 1 = "First option". List box value 1 = 35
List box item 1 = "Second option". List box value 1 = 44
List box item 1 = "Third option". List box value 1 = 3
If the user selects "Second item" from the drop down list box then that property do I use to retrieve that list item's value `44`. Also, when I pprogramatically populate the drop-down list, how to I set each lite item's `Value` property accordingly. As in the example 35, 44 and 3 Tried using `SelectedItem` and `SelectedValue`?
assign a particular value to each item in a combo box? Or, alternatively, some similar control? Specifically, I want a drop down list to select from a list of countries. I then want to get the ISO 2 letter abbreviation for the selected country. I could have a section of code like this
selected_country = cmb_country.SelectedItem.ToString()
if selected_country = "Afghanistan" Then
country_code = "AF"
ELSE IF selected_country = "Aland Islands" Then
[code]....
but this will get rather tedious.Is there an easier way to do it? I would like to be able to assign a value to each line in the list, like
Afghanistan, AF
Aland Islands, AX
Albania, AL
then get the value for the selected item. Is this possible? If not with a combo box, then any other control?
I am trying to figure out if i can assign a numerical value to an item in the check box. I have two forms one with the checkbox and another that will show the total amount based on what was checked in the checkbox.
View 2 RepliesI am trying to develop a recipe manager that allows a user to create a shopping list. I've already determined that I want to use a list view for this job. I want to be able to group the items in the shopping list by the appropriate grocery aisle (i.e. Dairy, Bread, Canned Goods, etc.) I'm not sure how to assign the items to the appropriate group as the user selects each item.
I haven't started actually building the application yet as i'm still in the development stage, but i have been testing the list view out to figure out how it works. i've figured out how to add items. i just don't know how to specify the group that each item should belong to.

How can I assign a context menu strip to a listbox item and not the listbox itself?
View 1 RepliesI have a property called ReplacementTo and I set a value to it based on the selecteditem from the combobox, like this:
classEquipmentItem.ReplacementTo = cmbReplcmnt.SelectedItem.ToString
Now I can't use cmbReplcmnt.Text because what I actually need is the value of that SelectedItem
So problem is, if the user leaves the combobox as blank, it throws a null exception.I decided to use the IIf function then:classEquipmentItem.ReplacementTo = IIf(IsNothing(cmbReplcmnt.SelectedItem.ToString), classEquipmentItem.ReplacementTo = "", cmbReplcmnt.SelectedItem.ToString)
Unfortunately I still get the error I tried using a Try-Catch for it and it worked, but I don't want to rely on the Try-Catch, so I was wondering is there a another way to work this through?

Admin assigns the authority and get a new form to the new assign in with vb.net & access. I am not sure about this,I need a way to do the new form assigned? How?Actually, this project is the admin will assign the authority to a manager, and the manager will get the password to log in. Then, the manager once log in and will get a form to set the rooms who is going to use and date, etc, this is multi-manager to handle the room setting jobs.But, I think, I got stuck, I am not sure how to do the new form, HOW DO YOU ASSIGN THIS NEW FORM FOR EACH NEW MANAGER??????

View 9 RepliesI got a Combobox with some items (item1-item7) to select and 54ish Buttons(sButton1-sButton54). Also an array(53) called Buttons. The array is filled with the items to select, like: Buttons(0) = "item 1, item 2" Everytime another item in the Combobox is selected, I'd like only some of the Buttons to change their Image. Therefore I got the array. If Item 1 is selected and Buttons(0) contains the item1 I'd like to change the Button1's image.edit: It works with changing the image of every Button:
sButton1.Image = My.Resources.image1
But I'd prefer to change all in one go (Loop) instead.
sButton(0) = "item1, item2, item3"
sButton(1) = "item2, item3"
sButton(2) = "item1, item3"

View 12 RepliesI'm creating a Win Form app in VB Express 10, which includes an animation. While the animation is running, it would be helpful to fade (maybe 50% opacity) a tool strip menu item's image so that it would not distract from the animation. I've tried to change the item's transparency in the property drop down, with no effect. I think I would need a function to add to the animation start button to fade the tool strip menu item's image to 50%. Then if the animation stops, or the image is clicked, a function to re-establish 100% opacity.

I have a listbox and I want to loop through each of the items to see if the string im looking for is inside. I know I could do .contains but that wouldnt look at substrings. The code im using looks like this:
While tempInt > Listbox.items.count then
if searchString.contains(listbox(tempInt)) then
end if
tempInt+=1
end while
Everything in the loop is fine but VB gives an error on the listbox(tempInt) part. The error is "class windows.forms.listbox cannot be indexed because it has no default value". get around the default value crap? I tried putting in a blank string but no change.
