Committing Information From A Form To A Database And Firstname & Surname To Checklistbox If Dont Exist?
Nov 2, 2010
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?
I'm trying to make a tool to view and modify a SQL database that contains our financial investments. The database I have works fine, ans sorts it every which way I want. However, I've been modifying the database after sales and purchases, through Management Studio, which is a bit laborious and potentially prone to error. So, I'd like a simple VB tool to view the accounts and allow changes.
I found a nice tutorial on how to assemble a tool that's pretty much what I want. Using the Add Connection Wizard, I connected to a test database through a User instance, added the datatables and produced a form that allows display and modification using a DataGridView.
im trying to add a new record in a small access database only firstName and lastname i want to chek if that record exist msgbox say record exist if not add a record here what i have done
Dim sqlcmd As String Dim cmd As OleDbCommand Dim dr1 As OleDbDataReader Dim user As Integer
I've built a contact book in vb08. I've created the database in ms access 2007. I connect in and show the data and drag it to my form it works 100%. I can add and delete entries everything but how do i add a search by surname option to the form?
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 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 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 problem that hopefully someone can shed light on. My OleDBdataadapters and OledbTableadapters have gone on strike In a simple vb.net 2005 pro project I have an Access 2003 .mdb with 2 tables each with 1 primary key and all other fields allowing zero length and not required. The database (not read only) is included in the project (see connection string below which works because data is presented on bound forms).
Although each table's data is displayed on one of 2 bound windows forms, it just refuses to update, add new or delete. I've deleted and recreated forms, etc, using wizards and just run time code but the problem is still there. I can change data manually in the mdb. The code below refers to a site mdb table and was wizard generated. I added an update query to the TableAdapter using the wizard, see sql below.
I have installed SQL Server 2005 Express and VB 2008 Express.
For testing, I created a database with 1 table with 4 columns. I used SQL Server to add 2 records. I then created a new project with 2 forms. On one form, I put a DataGridView control. On the other, I used bound text boxes. Both had a ToolStrip. I made changes to the data through the forms. Both forms seemed to work properly, except when I looked at the data again using SQL Server, the data had not changed. Opening the forms again, the data had reverted to the original data.
I am using the code created by controls, so it should work. When I use the Database Explorer in VB, it shows the table and the data and I can make changes to that data. So why is my code not committing the transactions?[code]...
I am trying to pass some information from a VB form to my MySQL database. i have named all the textbox's the same as the field in the database and checked all my database fields and textbox names which are all correct. When i try to enter information into a form I sometimes get an error at the .executeNonQuery section of the code.
To test, I outputted the SQLStatement string to a textbox ( which pulled through all the fields from the textboxes correctly) then manually inputted the completed SQL query into the database and it worked. But when I try to do this in one go it seems to fail if there is too much text ( if i enter 'a' into each field it works). Are they limits to the size of the SQL query that can be passed from VB?? all the MySql database fields are set to text with no size limits.
i have my code until now,like a set-up file.First when i click on my button it sends me to the form with the setup steps,when in setups it is copying a identical file into the startup menu.I want my button to check if i have that file into the startup folder,if i dont have it to send me to the setup if i have it to send me to the form with the program.I must mention that there are 2 forms,the setup form and the form with the program.Until now i tried this,but it dosent work so well...
Public Class Form1 Dim OS() As String Dim UserName() As String[code]....
Checks,if i dont have the copy-cat of this file it sends me to the setup where it is copying the file.And if i have the copy-cat in the startup folder then send me to the other form:).
The program is currently trying to pull information from three different database tables and compiling the information onto one screen, to do this i am using three different connections and a function to handle the data at each stage. The issue is as my code hits PageLoadStage of "2" and runs the QueryDatabase() Function i am encountering an error of: "OleDB exception unhandled: No value given for one or more of the required parameters." This occurs on line 15 of the first code snippet. Can anyone explain this and/or identify any code issues if that is the cause.
[Code] I want like to check if a file exist on main form, if not: force open settings form. And then when the user is closing the form with exit button = check if the file exist again. If it doesn't exist, close application. It's a huge application and I need optimized on most parts. Also, the settings form is asking the closing question two times.
could someone tell me what i am doing wrong in this codeProtected Sub insert_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Insert.Click
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 want to insert records in the database but before it inserts, it must first check the database whether the value being inserted already exists. Now my problem is that I am unable to insert into the database even though the value still does not exist.
Here's my code:
Dim check As New SqlCommand Dim sqlcheck As String = "SELECT SerialNumber FROM EquipmentDetail WHERE SerialNumber = '" & TextBox1.Text & "'" connection.Open()
