I want to make a program with vb 2008 and I face a problem, but firstly I will explain you what I have done already. I have a database(Microsoft access) named Receipts and there 2 tables Receipt and TaxPayer. At visual studio I've created one login form which I chose(from project properties) to be my startup form and another form Form1 that has a datagriedview which is connected to my database and gets data from the table Receipt. The validation of the user at the logIn form and tha connection with form1 works perfectly but here's my problem.When a user is valid I want to appear at the datagriedview of form1 only the records that have to do with him.I forget to mention that TaxPayer table has 3 columns,username,password and and a code(AFM). Instead all the records of Receipt appear. I know that the problem is at the Fill Method which looks like this:
I've got a datagriedview and records and i want to delete one record from this and also from my database.My datagriedview is a control and it is filled with records with the method Fill. So I created a delete button like this: 'Me.ReceiptBindingSource.RemoveCurrent() but this deletes a record ONLY from the datagriedview. Then I tried this:
the following code works fine on a unbound DGV on the main form:
If Not exist Then
.Rows.Add() .Rows.Item(.RowCount - 1).Cells(6).Value = file.Name newFile = newFile + 1 End If
on a second DGV on another form this code adds all the rows, but only the last row shows the inserted value, all other cells are empty. If I direct the same code to the first DGV on the main form it works fine.
I have a dataset called KeyData made up of two tables Customers and Orders.
I have two forms, one named MainForm that shows records from Customers in details view and the related Orders shown in GridView called OrdersDataGridView. The other form is called OrdersForm and is populated with the Orders table from the keydata dataset and shows records in details view.
When I navigate the MainForm customer records the correct orders are shown in the OrdersDataGridView. So far so good.
Here's the code that was generated when I dropped the tables within KeyData dataset onto the MainForm:
Private Sub MainForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 'TODO: This line of code loads data into the 'KeyData.Orders' table. You can move, or remove it, as needed.
I've tried a few different methods I could find in order to connect my VB .NET program to a book store's database. While I've been able to connect to it and display the contents of its tables in a DataGrid, I need to be able to search the tables and display specific records, depending on the contents of appropriate the adjacent text boxes.[code]This is a code I've used for a very similar process, just really aims to search a different field in the table. If this is easier to adapt into a code that allows searching and producing specific records in a database, please use this one.
I am creating an application with html using vb as the back end. Microsoft Visual Studio is the application I am using.I have two drop down boxes...one called department, the other program. When a department is selected, I want the program dropdown to only display the programs that are associated with the department chosen. I have found several different codes to do this but nothing has worked so far.
I am coding on Visual Basic 2010 and need some My Access database table has following information:
FirstName LastName PhoneNumber
Basically what I am trying to do is create a Search function where the user will enter a First and Last Name in the search boxes and upon hitting the ''Search'' button the program will look through the database and check if the records exists.
If the record does exist then I want the Phone number to appear in a separate textbox which is named txtPhoneN. I have included the code I use to connect to the Database. I have already managed code the part to Add new record to the database.
I'm doing a simple database thru VS2008 and Msaccess without using any builtin relationship between records, now i need to know how i can retrieve specific data from access using the oledbadapter or any, example seek if the value from the textbox1.text is already existing in msaccess table then msgbox "Record already exists.", note that the code is in keypress event of the textbox1.
I can retrieve records from my Database fine, but I'm having trouble updating records. I am getting a syntax error on [code] I get this error when I change the Last Name (Row 0, Column 1). [code]
I want to search the records from the textbox and display the records to the datagridview, if there are no records, just display empty on the datagridview.
this is not working: Dim sqlsearch As String sqlsearch = "SELECT * FROM setting WHERE mname LIKE '%" & TextBox.Text
I have this piece of code wich works perfectly when inserting records into one table using records from another table. My question is that now i need to create another table by using records from 3 other tables (tables are related). Can i use aliases on the column names, like on Oracle SqlPlus? How will be the syntax of the 'INSERT INTO SQL statement?
Dim MyConn As ADODB.Connection Dim MyRecSet As ADODB.Recordset Dim tmpSQL As String MyConn = New ADODB.Connection
I am working on creating a program that records animal data (wombats) and stores it into a database, using vb.net. I am trying to add new records into a database but every time I click add, to execute that, there are duplicate records that gets added. How do i write the code so itonly adds it one time. I am using a data reader. Here is the
I want to search the records from the textbox and display the records to the datagridview, if there are no records, just display empty on the datagridview.[code]
I wonder if it is possible to find a specific row and specific columns in data base file (Access) . You see , I am using a DataGridView control to show only SOME of the columns (fields) of a table from an Access file . For example , lets say that in the DataGridView control I only show the following fields :Field1 , Field2 and Field3 .Now , when the user selects an entry in the DataGridView control , I want to insert the text from Field4 into a text box on the form .
The problem , however , is that I don't know how to get the specific row in the data base file and also I don't know how to get the text in column (field) Field4 of that row .One thing that might be important is that the index of the row in the data base file is not necessarily the same with the index of the current row in the DataGridView control . This is because in the DataGridView control the rows are order by the contents in the ID Field .ol .
I have search system that works like charm: 1> Searches specific folder for text files which contain specific word 2> Puts those text file names and/or paths to listbox However i want it to put (instead of InputStr) the specific line where word is found in text file to listbox.
The below picture is generated by the following code:
Public Class Form1 Private Sub Form1_Paint(ByVal sender As Object , ByVal e As System.Windows.Forms.PaintEventArgs) Handles Me .Paint
[Code]....
What I want to do is when I click on each grid on the form (Touch Screen), a tooltip of some stored information about the grid appears on screen. For example, if I click my mouse on square 6,8 then some stored information such as grid number, grid name, level...etc appears on the tooltip on the screen.
I have a dataset containing 2 tables,Customers and Contacts. Just showing the master-detail is not a problem. Problem occurs when I try to search the master table to bring in the detail table. Searching the master table shows only the master record, but not the related detail records. Adding a 'findby' query on the detail table only shows the records.url.. Normally when the master table is filled, the detail record shows in a form.
I am trying to find a specific file in a specific directory and then i need to get the full path of the file.Is this possible i cant find any help topics about a specific file.
So im trying to get evything that has ends with .iso into a list box, tryed a couple of things but not getting anywhere as yeat
Here is code.
Dim Locate As String = Application.StartupPath & "\Games\" ListBox1.Items.Add(Locate.EndsWith("*.iso"))
The Locate String is there because thats the location where the iso files are but the application is in the root of the drive. The ListBox1 command is fairly easy to understand
Strange story... I downloaded VMWare but it has since advised of an available update. I downloaded the update and when I click to install it, a window comes up with VB Code from a project I created a while back in a completely separate folder from this install file. I then tried downloading the trial of VMWare Workstation and when running the installer it shows the same thing. I don't know of anyway to contact VMWare support since I don't pay for any services or products and all there is available is a FAQ type section. Of course this problem would not be in there, nor can I find any such related issue online. his is VMWare specific or perhaps the type of install specific. I have no other issues with any other app installations other than with VMWare installations.
I have a database with 3 tables: Student, Unavailability and Duty.The fields for Student are entered in a form I have. One of the fields in Unavailability is filled by a form, the other fields are an autonumber and a foreign key to the Student table.ow I want records in the Duty table to be created and automatically filled in depending on what the values of the fields are in the Student table.For example, If the Boarder field in the Student table is 'yes' then I want the Duty Number field in the Duty table to be '1', '3' and '4'. If it is 'no' then I want the value to be '2' and '5'. I recognize it will have to create several different records to incorporate the different duty numbers for each StudentID. Obviously this will require an if statement, however this is my first time implementing a database with my limited experience with programming and Visual Basic, so I don't know how to refer to the specific fields in a table and set the value of other fields depending on the data in other fields.
To refresh or invalidate only a region of the form.sometimes I will need refresh all the form, but in some situations only specific regions of the form..I saw some samples on the Microsft site, but I don't understood.I use VB .net 2008
