I have my random alpha-numeric generator giving me a list of 500 items. I need to be able to search the "random Plate listbox" by entering into a textbox. Partial matches will be displayed in listbox1. My code for searching the "random plate listbox" is not returning results.

I need to move items between two list boxes, I've never used list boxes before so this is totally new to me and I don't know where to begin, all I know is they work kinda like arrays.
So what I need is to move one or more items, from ListBox1, and move them to ListBox2 and vice versa
p.s. sorry to the mods just realised I havent been selecting a category to make my posts in, won't happen again.
I'm replacing a text box with a combo box. I'm doing this since there are a set amount of inputs for this value. I added the combo box and entered in the values.The problem is that I can't seem to get the value that was selected..I tried setting a text box to the contents of the combo box and nothing happened.TextBox1.Text = cbbct.Text..That is what I tried and it didn't work. This really confuses me since I use a combo box to open save files and that works nicely.Also I'd like to use multiple tabs for my program. I made two tabs then cut and paste my text boxes,buttons, etc. onto them. After I did that I could not open a save file and have it populate the text boxes and set the check boxes. Is there anything I should be careful of when moving stuff to a tab or cutting and pasting?
View 18 RepliesSo i have a "game", and the login screen for the game is built into a panel. When you click the load button the panel shows up inside the form, and you are able to type in your username and password. what i am trying to do is make it so the user is able to drag that login panel anywhere inside the game form; just to make it a bit more advanced then just a fixed spot.

how to determine whether the property in question is a generic List(Of T)? If it is I need to loop the list itself.
I've experimented with GetType and TypeOf but have not managed to get anything working.
To clarify, I want to keep this generic. I do not want to specify the type of T, I need to loop the list items and call the ToString method on each item. T could be one of a number of different types (application specific reference types). Is it possible to do this without specifying types?

This program is supposed to allow the user to check items in a checked list box. If the item is checked, it goes into the Completed List Box on the right. The program then adds the unchecked items to the Pending list box on the left. I keep getting placement values (e.g. O,1,2) instead of the strings (e.g. "Key Returned") in the list box results (see photo attached)

Another program I am working on for fun, I am basically shuffling a list inside a listbox, what I want to do is delete the rest but not sure how to go through with that. At the moment I have this: [code] Just contains the code, declarations outside weren't included.So anyway, once clicked, it will call on the function to basically shuffle in a for loop, I was wondering if I should (or how should) create another function and call it in the click button or have just a loop in the click button so it deletes half the list. What I am doing is I have 20 list of items, I want the program to shuffle the items and then deleting the lower 10, meaning, if I had 10 items and wanted 5 top, I'd want: 0, 1, 2, 3, 4 and deleting 5, 6, 7, 8, 9.

I have an error panel that is subbed in to a page if an error goes wrong to gracefully handle and display errors.Currently, I am just appending the error messages to a string and pushing that to a label.

I want to know how to test the 1st list box if it has items more than the other list box but by one item, here is what i have: If lstInvisibleTv. Items.Count > lstInvisiblePc.Items.Count Then it works good if the lstInvisibleTv list box is greater than the other list box by one but it also works if it is greater the other one by one or more which I do not want. I want it to work just by one.
View 3 RepliesI have a program that will compare an array of grocery list items glist and an array of coupon item clist.When I compare the two and if there is a match somewhere in the array I want to have a picturebox visible.When there is no match, I want the picture box not to be visible. [code] The code seems to work great until I come to the else statement.When the code finds a match it displays the picture box and the msgbox without error, but as soon as the message box is cleared, even though i've input it as an ELSE statement, the picturebox goes false again.Does anyone have any idea of how I can "hold" the picturebox to stay visible while the match between the arrays exists?
View 18 Repliesi am writing a program that reads a excel report from accounting software with our weeks orders on... so basically the program reads a list of around 100 items which all works fine.I also have a database that holds info on each item, when the excel sheet is parsed the software checks to see if any new items have been added to the list that are not on the softwares database. this is where i am having the issue.I have two lists: ItemsOrdered & ExistsingItems.
All the items ordered this week are in ItemsOrdered and all the items not in the items in the database are in the ExistsingItems list. using these two lists how can i find items that are in ItemsOrdered but not in ExistsingItems.
