i am trying to add subjects and their corresponding grades to a table in you database. the table has these fields: Table1(subjCode,stdID,Grade1,Grade2,Grade3,Grade4,Grade5,Grade5,Grade6,Grade7,Grade8)And i have a checked listbox for the subjects and another for the grades. for each subject, the re are 8 items in the chklistbox, checked. The code should insert into the database a subject and its coresponding 8 grades
but when i try to Save i gives me an exception that index out of range(index was out of the bounds of the array)
I have 3 CheckListBoxes, and I want to save all of their "checked" states. I tried to change the code to save and load one to work for three, and this is what I came up with:
vb Private Sub savechxlst() Dim FileStream As New System.IO.FileStream("C:CheckedListBoxData.cld", IO.FileMode.Create)
[Code]....
Unfortunately, all this does is combine all of the checkboxes into one list (ChxLstSym), and leave the other lists (ChxLstAud and ChxLstEx) completely blank. By this I mean ChxLstSym ends up having 15 checkboxes instead of each of the 3 Lists having 5 checkboxes (Which is how it was before I saved and Loaded), though it does remember which boxes were checked originally.
Is there a way to fix this so that I can save and load the checked states for all three of the checklistboxes (ChxLstSym, ChxLstAud, and ChxLstEx) so that they are all in their own lists upon loading them?
My application is in VS2008 coded in vb.net.I have a form with a datagridview which loads data from databaase.there is one column where data is stored separated by comma's.Like Name,Surname,LastName name this column as Testing.I have a checklistbox on another of my form.When the user selects a particular row from datagridview another form open and the row selected records are populated in the control of my other form.My issue is i want to check those items of my checkbox that are present in my Testing Column.I have used and array im able to fetch the records just im not able to check the items in my checklistbox that are present in the column
Below is my code
chkList is my checklistbox controls FORM1 is my form that has datagridview
Below is the code of my second form that has checklistbox
Dim classesChecked As String() = FORM1.DATAGRIDVIEW.Item(10,FORM1.DATAGRIDVIEW.CurrentCell.RowIndex).Value.ToString.Split(",") For i As Integer = 0 To classesChecked.Length - 1 Next
I have a CheckListBoxthat is filled with items from an array. I want the user to be able to select the items they want to remove then press a button and have the items be removed from the array. I have never worked with a CheckListBoxthat before so I'm not really sure how to go about this. Here is what I have tried so far:
Private Sub btnRemove_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRemove.Click Dim TempNameList As New ArrayList If cmbRemove.SelectedIndex = 0 Then TempNameList.AddRange(NameList) Array.Clear(NameList, 0, NameList.Length)
When I re-display the array into the CheckListBoxthat it shows that nothing was removed from the array.
I've searched the forums and have only found similar things for ASP but not this exact function in VB.
I've got a checklistbox in my program which has 8 choices. I'd like to append the selected indices (the text not the index number) to a textbox on my form. How would I do this?
I have a check list box. i am displaying the course names in that. user can check the courses they want to follow. they are allowed to select maximum of three courses. how can i get the checked course names into a string variable array.

I am writing some code and want to check if certain things are in my database. Is there a better way than just creating a new string, performing the select and storing it in the string? I have to do this a few times for several items in my DB columns, but is there a way I should be doing this that would not require me to make a new string, and a new select for several items, well a better way? The items in my db aren't all strings and the data types vary.
a save button called sl and basically I want for all the items in my listview to save to the database I created called logins and I have 4 columns Email,Password,Proxy and Port. So how would I make it save to the database when I click that button. Also how would I make the database load automatically into the listview when the program is opened?
I have some items in my listbox which I will store everyone of them into my database, what I am doing now is looping the box and call my database saving logic to save every single item. I thought this is pretty inefficient, is there anyway that I can use to batch save my items so that I don't open and close the connection as many times as my items.
For Each item In outletToBox.Items .CamCode = Items.ToString .CamCampaignAutoID = retID .CamRemarks = uitxtCamRemarks.Text.Trim '---use savetable object to save to database table--- Next
Can i select multiple items in a Checked list Box? I have been tryng for soemtime now but I just dont seem to get the multipe selectd items even when I put it in a loop! Listbox has the member of being Selected. A checklistBox doesn't why? I need to select mulitple items in a CheckedListBox and save it in a database.
and here is the escalar command that i use to save to mysql db.
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click Dim connection1 As New MySqlConnection(connStr)
I do not have any code to show, but using asp.net, vb.net, and SQL with stored procedures.If on a page I have an item that is added to the database and therefore that information is "saved", is there a way to have an ("exit without saving") button on the page that does away with those changes?Using infragisitcs ultrawebgrid, you add an item to one table. You can add an item to another table on that page. i assume adding these items to the table automatically saves in the database. There is also a text box but without clicking save I do not believe that those items are actually added to the database. Update panel is used, I don't know if that matters.
If after someone adds to the table but then decides.. oh wait.. I don't want to do this just yet, is there a "one-click" way to act as if I never visited that page to add info? I'm assuming it would be deleting the entries but this would have to be limited to deleting ONLY those items added while making... we don't want people adding info, then going back and deleting once the "save" button has been pushed.
I would like to be able to save to a db and send task to email or as text msg for instance nevermind that.. I have two variables of type ArrayList they are "_mList1" , "_mList2" and "_mList3"
_mList1 stores the list of Telephonenumbers , _mList2 stores the list of StaffIDs and _mList3 Some concatenated string.
theses variable lists will hold some data in runtime as explained and i would like to use them to populate a DB table again mentioned
I would like to make a checklistbox which relates to a database, in that there should be the same amount of Items in the check list box as there are records in the table.
i was going to make a for loop for the amount of records in the database each time adding a new item to the checklistbox but im really not sure how to do that!
Using command As New SqlCommand("SELECT player_name FROM player_table", _ connection) Using reader As SqlDataReader = command.ExecuteReader()
1) i want to make my login page (which talks to a sql table called logins) my first page and it authenticates to that database and doesnt let you in until correct credentials are entered. ? not sure how
2) I have a Checklistbox that is populated with names - ( i want to be able to populate a database called members with those names(Firstname & Surname Only) and from a New members form populate the same members details into the members database this time including address email tel etc etc ....
3) create a delete button that will delete the information from the database and from the checklistbox1 (this is in case the member leaves the club).
4) how do you create trial versions keys etc ...
5) change a progressbar timer to last an 1½ and show hours minutes seconds but once the button is hit to stop the timer it automatically resets to zero.
i have problem here regarding update data when i checked value in checklistbox control.no problem when i want to insert data for the first time, but got problem when i want to update it where the previous data that i checked is still available, plus the latest data i checked. Thats means I got multiple data in my database.
example:
cat lion mouse previous( cat) > i checked cat only
latest in my database, i got (cat,cat, mouse) when i checked mouse and cat.
I have a checked listbox which is populated with names(firstname & Surname), I also have a form that has been designed (layoutwise but with no code) to be populated with personal info such as name address,postcode,email address, sql database defined in the program that has a table called members that has the same column headings as the members form.
What i am trying to figure out is how i can commit personal information on my form to that database and copy the firstname and surname from that form to the checklist box if they dont exist? how do i go about this codewise?
On my program I am trying to make so the combo-box's items save after when the user adds something to it. Like if the user closes the program and re-opens it can the items that the user added still be there?
Am using this INI Reader from CodeProject. I have a listbox with some items in it. I wanted to save the items in listbox to my ini file. I used the following code but the problem is, it only saves the final item.
Dim INI As New IniFile INI.Load(Application.StartupPath & "Config.ini", True) For i As Integer = 0 To List.Items.Count - 1 ini.GetSection("Initiate").AddKey("Part1").Value = List.Items.Item(i) Next
I am happy that there is a forum like this with very supportive people.So on topic.I am a student creating an Inventory System software for my school using VB on VS 2008.I am having trouble saving items from a DataGridView to Access 2007.The codes I browsed here are quite different from what instructors teach us at our school.These are some of the codes we are using to save items from textboxes to Access 2007 database with a table named studenttable and database named student for your added information.
I'm trying to save each item in the listview to the database.Below is my code in saving items in the database. The MISSING CODE HERE is where I should place the listview item.
Dim commandText As String = "INSERT INTO tblBorrower (TransactionNo, IDNumber, SerialCode, DateBorrowed) VALUES (@TransactionNo, @IDNumber, @SerialCode, @DateBorrowed)" Using connection As New SqlConnection("Data Source=GAMER-6SQLEXPRESS;Initial Catalog=dbInventory;Integrated Security=True"), _ command As New SqlCommand(commandText, connection) command.Parameters.AddWithValue("@TransactionNo", intTransaction)
I have run into an issue and need help solving it. I know how to go about adding items to My.Settings and I have already created the Specialized String Collection to My.Settings called List but I am having some trouble getting the items and the subitems to save to the list.
