I've got a form here with a listbox full of words. I'd like to allow the user to insert new words and have it update the database it's getting the data from. Can I have it display a msgbox, the one that takes input from a user, and use that to update the database?
View 13 RepliesSo I'm making a program that has a few selections from a ListBox, and when one is selected, it will clear/load items on a groupbox. However, when I add a label, it will only display the first 2 or 3 words.Here is the code I use to add a simple lable, that doesn't work:
If (ListBox1.Text.Equals("Mode")) Then
RichTextBox1.Text = notes
GroupBox1.Controls.Clear()
[code].....
I have a form with a Label. And Label1 Show's the day Date Time. But How do I separate the Day, Date, Time, as you can see in the picture below I have Managed to put a space Between Day and Date but not Between Date and Time I have tried " " without success.
Private Sub Timer1_Tick(sender As System.Object, e As System.EventArgs) Handles Timer1.Tick
Select Case Weekday(Now)
Case Is = vbSaturday
Label1.Text = "Today is Saturday " + Today + TimeOfDay
Case Is = vbSunday
I'm attempting to setup a search function from a string a user types. (ex: "John Doe" or "Doe, John") I was thinking I would use Replace(SearchString, ",", "") to get rid of the commas the user might enter, and then use Split(SearchString, " ") to get all the words into an array. Once they're in the array I would execute a Stored Procedure on each of the terms and build a DataTable with the results.
Below is what I'm wanting to use for executing my stored procedure.
oCommand = DataAccess.GetSQLCommand("MyStoredProcedure", CommandType.StoredProcedure, SourceServer.ConnectionLocal)
oCommand.Parameters.AddWithValue("@MySearchString", SearchString)
[Code]....
Now I'm thinking the "SearchString" I will assign while looping through my array of words... but this doesn't seem like the right way to do this. Maybe it is but I don't know how to append my next result to the previous DataTable either.
I want to make fill my database with 2 fields.1) a specific word2) the definitiontherefore I am using a blank database program in Microsoft Office Access 2007...the blank database has 3 fieldsIdfield onefield twofield one will insert the wordfield two will insert the defintionmy question is this:does the database grow dynamically with the insert or do I have to specify how much memory?
View 2 RepliesI've got 2 RTB one is for input of text and one is output.The output one needs to read the words from the input and display it alphabetically and with their line numbers.I have partly done it and it currently reads it but here is my problem When the words are outputted let say for example there are 2 words the same on the same line e.g the word 'you' appears twice on line one,at the moment its coming up like this

I am trying to create a web-method to check whether a string contains a word which is in a list of 'not allowed' words. This list will be updated from time to time.
<System.Web.Services.WebMethod()> _
Public Function checkword(ByVal Id As String) As String
Dim returnValue As String = String.Empty

Something is wrong with this function. It verifies the first word of string. After that it doesn't return anything.
searching a database using multiple words from a textbox showing in gridview.
<asp:TextBox ID="TextBox1" runat="server" Width="382px" AutoPostBack="True"></asp:TextBox>
<asp:Button ID="Button1" runat="server" style="height: 26px" Text="Button" />
[Code]....
It works fine, i click button and the gridview shows all the right records. The problem is when i use more then 1 word in textbox. it shows nothing. The record in the database field may have several words, so i need to search using all words in textbox.

other than GML (Yoyogames.com Game Maker Language), I am new to the coding world. The only "major" project I have completed using VB is a computer calculator that exactly mimics the capabilities of Windows 7's calculator. Yesterday, I began a Chatbot program for my girlfriend. Lol. I have used the instr() function to answer most of the questions or answers which are typed into the textbox1. I find this extremely troublesome because when using the instr() function you cannot say instr(textbox1.

I am looking for the simplest way to push a new row to a database by inserting one record and then retrieving the Primary Key generated by inserting that row.
I know there are several ways this can be done but I can't seem to get any of them to work yet.
I have made a form that has three labels and textboxs and two buttons. The labels arelblPersonID, lblFirstName and lblLastname. The textboxs are txbPersoonID, txbFirstName and txbLastName. The two buttons are btnSave and btnQuit with "End" in htis button. I have also made a database "MyFriends" with a table that has PersonId, FirstName and LastName.
I want to be able to type into my textboxs and have that information saved as a neww row.
Anyway, if I use a web service I need the web service(server) to connect to the databasen MS Visual studio when you add a web service project the data menu disappears and you can't add a data source to the project.

I have a project I created for my VB class where you enter what type of ticket(combobox), how many tickets(textbox), what type of tickets(listbox) and will give you the total amount.I want to do a little more to the program and was wondering about adding the person's name, address, phone, city, state, zip and then having all the information put into a database. I wanted to also take the information entered from the program and use the printPreview control to view a report from Access(possible?).
I've only worked with viewing database information on the forms in VB but I've never entered data into the database. Is this possible?Can I have the information entered on the form be entered into a database that keeps track of all tickets purchased and customer information?I can see this working in my head but don't know if it's logistically possible.
create a adding form and it will save to sql database .

My program has an access database with a table called "Contacts". This table stores many values. I have a seperate table that stores surveys. Each contact should have a column for every survey, indicating whether or not the survey has been completed. However, this means I need to add columns to the database while the program is running. I tried the following code, which runs WITHOUT errors, but does not seem to actually add the column.
contactsDataAdapter = New OleDb.OleDbDataAdapter("SELECT * FROM Contacts", frmAdmin.con)

We're trying to work out some code for saving from a textbox to a database field without using DataGridViiew. We have it working using the automated controls that Visual Studio gives us, but if we have a form with text boxes, can we make it so that, on a button click, it dumps that stuff into a field in a table?

I'm new to databasing. How do you make it so you can add an item to a database on a form, Then follow a link to another form which has the database on, then what you put in on the previous form will be there?
How's it done? Sorry - Haven't been using VB very long >.<
