Listbox2 Check If An Item Is Already Exist In Listbox1
Mar 15, 2012
in form1 i have two listboxs listbox1 listbox2 loadbutton and savebutton this code will write listbox1.selecteditem into a txt file and loadbutton will load info in listbox2 but i want when i click loadbutton it check if that item is already exist in listbox2 , if not so write selected item from listbox1 and if that item is already exist in listbox2 then do not save it (msg"this item is already exist in listbox2")
I am making a password program that remembers what the password is for and what the password is. I have two listboxes: 'listbox1' for what the password is for, and 'listbox2' for the password. I also have a remove button. I would like it so when you press the remove button, the selected item in listbox1 is removed and the password in listbox2 is also deleted. The passwords are stored in two settings: what, and pw. The items that will be deleted will have the same value. By value i mean they will be the same number item. E.G. the 1st item, or the 3rd item in the list.
I have already achieved above but the main difficult part is I also want numbering in listbox2 to go green or red based on listbox1 item (Corresponding items)
Uploaded with ImageShack.us how can i move the highlighted listbox on the right side to the empty row(the one that is highlighted on the left side) using a button.
here i have 2 listbox i already have the code for the selected item moving right and moving left but i don't know how to move all of the listbox1 to listbox2 by just click >> or listbox2 to listbox1 <
I have a listbox2 and it is bound to my ms access database. I want to number them using listbox1. Example
[Code]...
** the listbox1 must automatically number the items depending on how many items inside the listbox2. -I already know that i can make it by creating autonumber in ms access, for certain reasons i cant do that.
So I have two ListBoxes. Listbox1 gathers files from a directory and I have an add button to add selected files from Listbox1 over to Listbox2.
Is there a way to manually sort these items? Maybe with an up down buttons?
The reason I'd like to sort/reorder is I'll have a process that will run those selected files and each file will have to produce another file unique to the filename.
A quick example would be process FILE1.txt and produce FILE1.pdf, etc.
Is there an easier way to accomplish the sort/reorder?
UPDATE
Here is currently how I'm populating my listbox1, before adding anything to listbox2, which is the ListBox I'd like to have sorted so way or another.
Dim directoryInfo As _ New System.IO.DirectoryInfo(FolderBrowserDialog1.SelectedPath) Dim fileInfos() As System.IO.FileInfo
Okay as an example i am opening images through listboxes. Say I have the name of the photo in listbox1 and the location name of it in listbox2.Okay so what i want to do is make it so if i select an item in listbox1 that it will select that item down the list in listbox2 but by location not names.
I have 2 listboxes, and i can't get out what i need to do for the method. The method is, if a item in listbox1 is selected, it will select the same line in listbox2 and same in reverse. there can be many many items.
what is the fastest way to check if Item ID exist in the database?
From what i have done, i have an excel file uploaded to datagridview, then each itemID is retrieved line by line, then accessed the database to check if ItemID exists.
Is there a way to retrieve the whole column of itemID and then query it to MSSQL2000, then display the itemIDs that does not exist.
i have two listbox who contain Directories File one listbox show Full Path of Files..Second Listbox Show Name Like Show in Picture:i want to start new process by click on Listbox2. selected item( contain only name of files )
well i was trying to do a function called Procedimento() for each item in listbox1 but it's impossible .... how it can be done ? What i try until now :
Dim myItem As Object For Each myItem In ListBox1.Items Procedimento()
I want to create a very simple database. form1 - ListBox1, textBox1, buttonadd, buttonremove. The item collection of the ListBox1 is stored in a txt file along with a string that will be displayed in the textbox1. the file will look like this ( like a .ini file):
Private Sub ListBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged If ListBox1.SelectedIndex = (last item) Then
i have a list box which is populated with folder names via directoryinfo, and i have a second listbox which is also populated with folder names from a user selected folder. So listbox1 is populated like this:
Using VB.Net and Sql Server I want to check the user Entry Value.The User is entering the code in the textbox, before saving to the table, i want to check whethere code is already exist in the table or not.
Tried Code
cmd = New SqlCommand("Select code from table where code = '" & textbox1.Text & "' ", Con) dr = cmd.ExecuteReader() While dr.Read() End While
If value is exist, then message to the user "Already Exist" other wise save to the table.
I have a listbox populated from a column in a table. The data in the column contains some of the same data for etc. The word watch would be there 10 times but I only need it to show once.
I had it working at one point now it does not want to work. Im checking the registry for a subkey and I know it exists but vb is telling me it doesnt, which is driving me up the wall, this is what I got[code]...
This code works. i insert 3 string and then check if the database already save this code.if the first string does not exist it works well.but when 1 string "already exist" or found in the DB, all of the next string say its already in db even though it haven't. what should i do?
For count = 0 To strArr.Length - 1 If strArr(count).Contains("=") Then str1 = strArr(count) coun = str1.IndexOf("=") str1 = str1.Substring(0, coun)
