Loading Text (strings) From A Database Into A Label.text (so Text From Database Shows Up Into Label)
Apr 4, 2011
I have a form that I am loading text (strings) from a database into a label.text (so the text from the database shows up into the label) I have done this code in a class that keeps all my database stuff seperate.
Public Function getQuestions() As List(Of String)
Dim question As New List(Of String)
objConnection.Open()
objReader = objcommand.ExecuteReader
[CODE]...
Within the form that the label is in I have done this code
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Label1.Text(db.getQuestions().ToArray)
End Sub
I am basically making a quiz, so that when the form loads, question 1 is on there is 4 possible answers. You then press next button and it goes to the next question.
I am creating a game where i have made a login form thats uses the mysql database for the user accounts.The database stores account's login info, level, XP, Coins.
Those who are looking for an example like this, might find it useful (or not). I know i was looking for one like this for over a week. Ok now, to make this codes work properly, you have to make a Database in Ms Access (I used MS Access 2007) . Create a table of two Columns, one name Debit and one name Credit. Both of the Columns Data Types must be Long Integers or you might get some conversion errors at run time. Now save the database in Access 2000-2003 Database format. And last of all, put the database in your projects DebugBin directory to avoid the database Connection Errors.
I'm using Visual Basic 2008 Express Edition, so I have a combobox that gets filled with items from a data base made with Microsoft Acces, the combobox is filled with the values stored in a column from a table in de database so the user can select an "option" from it, I want to add labels that show the values for the corresponding row of that column. I used the Data Source panel to drag and drop the labels corresponding to the values that I want and it works it show the value that I want when I compile the application (at least I think it does, it could be that it's only selecting the first entry) the problem is that when I select a diferent entry on the combobox the labels don't refresh with the new values. How can I do that?
edit
how does Visual Basic Populates de combobox and gets the value of the other Acces DB entrys to change the .text value of the labels? And I mean the actual code that does that.
I have sucessfully written in excel VBA. The idea is to used the textbox1_change event to find a match in column A of table and once it finds the record, return the value of column B as label1.text. [code] In VB 2008 it's a lot different. I have set up the form the same way with the textbox and labels. I have made a dataset with (1) table (Table1) with (2) columns. Lets call them column A and Column B.I have added the dataset as a binding source to the form and also a table adapter. I also have a standardized query made for the dataset with a very simple SQL statement "SELECT Column A, Column B from Table1"..In order to get the user input to start searching Column A I assume under the textbox_change event i would put something like: [code] I'm getting a bunch of errors of course. Would somepne be able to give me some direction?
I would like to have a label's text recorded into a database when my button is clicked. I do not yet understand the database connection. I have created the db, and have the following
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim Conn As String = "Provider=Microsoft.SQLSERVER.CE.OLEDB.3.5; Data Source=c: empTestDB.sdf;" Dim tConnection As New OleDb.OleDbConnection(Conn)
[code]....
When I try to test this the .ExecuteNonQuery() becomes highlighted and says the given type name is unrecognized. My table is setup as table1 and the only 2 columns are datetime and temperature. I want the label text to go to temperature and I would like somehow the time the temperature was taken to go into the datetime field. I had the provider=microsoft.jet.oledb.4.0, but I changed it since I thought this was the one to use.
The code above is what I am using to add the Value of Label 1 (Pizza Total) and Label 2 (Drinks Total), however it seems that in the final total it doesn't appear to add the value of Label 2.
I have a label in a master page (sample.master) called lblHeading.I want to dynamically change the text of the label when I load the content page.I need to do this because I want to change the heading to something meaningful but only after I know about the content of the page.
I am having trouble adding label.text, datetimepicker.text and ComboBox1.Text into listview1 box.I have set up multiple columns, one for the label, one for the date and one for the combo box text. All i have done is:
Is there an effecient way to give one label the ForeColor, BackColor and Text of another one of 3 possible labels? I need to do this frequently for a dozen labels in a windows form.
I am using a label to display a song for an mp3 player. I wanted to scroll the text inside the label for anything that is longer than the label width. I figured out the width of the label and if the width of the text inside the label is longer. But I have no idea how to turn this into subtracting parts/pixels of the text currently displayed and how to append the subtracted parts to the end of the new text.
Sub f1timer2tick() Dim g As Graphics = f1l2.CreateGraphics Dim s As SizeF If f1l2.Text.Length > 19 Then
I have a label that reads a random line from a text file and that string becomes the text for the label.
Now the problem; the label will only work if it is clicked because the event handler is click.What I need is this to work automatically at startup. In other words, it should change the label's text to the random string of the text file on startup of the application.
I cant seem to find any link or topic regarding my problem. I have 2 forms in a project, form one has labels and adjacent combobox while the other form (form 2)has textboxes with adjacent combobox. I am supposed to change the text property of the labels using textbox entry from form 2 and add/delete/change combobox contents in fom 1 using entries combobox at form 2.
I would like to know if there was a way to loop through all the checkboxes on a form and if the checkbox is checked then I need it to copy the text from the checkbox and the label. Thera are 23 of these labels with two checkboxes for each.I need to be able to paste this in notepad and have it formated as such
basically i need to change the text of a label where the name of the label comes from the value of a variable.So, for example,
Dim x as String = "lblTarget" Dim y as String = "Target Text"
In this case the text of "lblTarget" would need to be come "Target Text". Basically, the label that is named the value of variable x would need to take on the text of variable y.
Is there any way to detect if the text in a label is longer than the label itself (assuming autosize is set to false)? I want to trim the text in a label so the last line is a finished sentence (everything after that sentence is removed). I hope you understand what I mean.
I want to go from this:"Hello. This is a test string. Most test stri..."
I am wondering if there is a simple way to make the text to speech occur after the updating of label.text
If I have the following:label.Text = "words words" voice.Speak(label.Text)
I would like the label on the form to display "words words" before it speaks. I'm a beginner with vb, and the only thing I could come up with was to use a timer. Just wondering if there's a simpler/more sophisticated solution.
I have this problem but I already simplify the code as below:Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Label1.Text = "hello" System.Threading.Thread.Sleep(5000) 'MessageBox.Show("hahahaha") Label1.Text = "world" End Sub
What I'm trying to achieve here is, after I click the button, the label1.text should change to hello, and after that to world. But I couldn't achieve that. Instead when I click the button, it just paused for 5 second and displayed world.System.Threading.Thread.Sleep(5000) The code is just a dummy for a loop that I have.
My application outputs log text every so often and I need the user to be able to see the latest text at all times. I've tried a label, a text box and a rich text box, but I can't figure out a way to show the bottom-most text at all times.
I am new to the forums and just started to learn vb.net. Currently I am making a project that require a lot of text. Since I would need over 20 labels and do not want to hide every single one, is there a way to place text on a specific place on form through coding. Then, I could just make it a sub and easily hide the text and reveal it
I have an SQL database, and 50 text files, and Visual Basic 2010 Premimum,I need to find a specific line of text in the text files and then take the next 37 lines of text and save them in my database. I need advice as to point me in the right direction
This is the only way I know how to obtain the info I need for this equation but if generated again with no input from the textboxes I get an error. Is there anyway to bypass this if its generated a second time with no inputs?
I am making a simple form which has multiple hidden panels and quite a lot of text on it.The form has 7 panels with 2 labels (or would you recommend I use text boxes?) per panel,which I was going to set to a specific line from the text file. My rationale was that if I wanted to edited the label's text I only had to go to the text file.
I have been trying for several days to create a serial port program that will send data and recievie data first off here is my code:
Imports System.IO.Ports Public Class Form1 Dim Connected As Boolean = False[code]....
The problem I have is when I run text like "AA" through a Logic Analizer it shows up as the value 01000001 but I want it to show up as 10101010. how to use the module in the normal code to make it do this?
