Display The Square Root Symbol On A Button In A Windows Form?
Feb 11, 2011
I'm trying to display the square root symbol on a button in a windows form. I'm using the unicode U+221A which on windows character map is the root sign. When i enter this in visual basic ensure the font is the same as that in the character map (wasn't sure if that made a difference to the unicode) my button displays the eta sign instead. Any help greatly received.
This is the code i'm using to set my unicode the the buttons text property.
btnSquareRoot.Text = CChar("U+221A")

Well, the code I have only gives the the number IF its like 2 x 2 or 4 x 4 is in the text box (4 or 16), but if its a number that can not be multiplied together to get the value in the textbox, it has an arithmetic overflow, what can I do to make it work for all numbers?
Dim Value As Integer
Dim ValueToMultiply As Integer
ValueToMultiply = 1

I'm using VB 2010 and I'm trying to populate a combobox with a name followed by a square root, but all that I was able to obtain is a name followed by an image of a triangle with a question mark at the center. I've tried to change the font but without result.

if there's a way to just display the latest Symbol when drawing a graph. My app displays "real time" data from a pointPairlist and I want one graph just to be a + mark with no trace.
Dim myCurve As LineItem = m_graphPane.AddCurve("", m_pointsList, Color.Red, SymbolType.Plus)
This will show a red line with a + with every pointpair, I just want to display the latest pointpair, as an +.

I have taken over support of an application at the company I work for. All of a sudden, the customer wants to be able to enter a registered trademark in a name field. The symbol, using ALT+0174, is being saved correctly, but the app is not encoding it properly. Essentially this is what I'm doing:
Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click
Dim ms As New MemoryStream
[Code].....
Everything is fine, except the "??" after "Smith" should be "®". What is the best way, if any, to display the symbol correctly?

Write an application that prompts the user to enter the size of the side of a square, then display a hollow square of that size made of asterisks. I have seen javascript using this but nothing with Visual Basic.

I am trying to build an oscilloscope; I will be using a signal coming from digital encoder going through MAX232 logic level converter to the PC via the serial port 1. The signal from the encoder is 3VDC when it is high and 0VDC when it is low, the encoder resolution is 1024 PPR, the encoder is attached to motor (1800 RPM) so the max resolution is 1843200 pulses per minute or 30720 pulses per second. I would like to make my form display the changing of the input from the serialport1 to graphical display just like the digital oscilloscope. I
I want to be able to display the signal as on and off (square wave) from the encoder and be able to display the signal as speed so when the motor is running at full speed the line be at the top of the graph and when the motor drop to 20% of its full speed the line will drop to 20% and so on.

I have created a button in a UserControl. I have added that button to a WindowsForm in another app and added a buttonclick event to the code. When running (debugging) the app and clicking on the button; nothing happens. It doesn't act like a button at all.
The code for the button click event in my test app is as follows:
Private Sub Element1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Element1.Click
MsgBox("The button has been clicked")
End Sub

I had created a windows forms application in vb.net. It contained several windows. Now the users of that application are telling me to display all in one main form. They want to see all the details in one form. I had implemented MDI but they want something like tabs. On different tabs different forms should be displayed. How shall I implement this.

I'm using VB 2010, accessing a MS Access database. I have constructed a simple Windows Form returning data from the db, one field of which has a reference to an image I'm trying to display together with the data from each individual record.
I have a field with a product number, that matches the jpg file name (ie, the product number 5505 matches an image that I want to display, namely 5505.jpg). I've even created a new field in the db called 'Image', that contains the full name 5505.jpg.
So, I've connected to the db with an OleDbAdapter, and all the data fields are displayed via bound textboxes. I've been able to display a single 'set' image with a PictureBox, but I'm not sure how the make the connection between the returned data (txtSearchImage which is, say, '5505.jpg'), and getting the Windows Form to display this.
Am I on the right track using a PictureBox? I've tried binding this via the PictureBox properties to the relevant data field, but (obviously) it doesn't make the connection to the image file on my hard drive.
Here's my code so far:
Public Class Form1
Private Sub btnSearchKits_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearchKits.Click
' The following line passes the value the user enter for state

I have developed a small application. It has a MDIParent form on which the other childforms are displayed. I have a Panel on the MDIParent on which there are buttons to call up the MDIChild forms. Now my issue is, when anyone of the buttons on the MDIParents form Panel are clicked, it should check if another Childform is display, if it is then it (the active childform is closed) and the new form will be displayed. This part is working fine from the code below. However, when there are no active MDIChild form on the MDIParent form and if the button is clicked, the 'Else' part of my code below is executed. This generates the error as 'Object reference not set to an instance of an object'. So what is wrong with my code below?
Private Sub btnExecutive_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExecutive.Click
Dim MDIChildForm As New frmExecutiveInfo

Just like an array in a group box or a frame as i used in vb6.
If there are 5 customers details then when i load the form it will add (PictureBox, Label and a listbox) for each customer dynamically and display them with their information. Moreover, if i add 6th Customer information in the database then next time i load the form it should display his/her information as well. I did this in VB6 sometimes back but need a start to do in .net
Private Sub LoadCustomerInformation()
Dim Qry As String
Dim RS As New Recordset

I need to display 3 columns and a varying amount of rows (typically around 50) in a windows form, kinda like excel. The data will likely be longer than the window, so a scroll bar will have to come into play somewhere.

I've been working of a Visual Basic Windows Form in Visual Studio 2010 as my first little VB project. It's a form which runs a stored procedure on SQL. I have this all working, however, the stored procedure has a PRINT statement execute if a duplicate is found and stops. What I'd like to do is have this PRINT statement display on the Windows form MessageLabel (label) or have a "successful" message displayed if there is no SQL print statement.

I'd like to use a TreeView control to display database data in a windows form with VB2008. All the information what I found is related to a website design, but I'm working on a database program (sql2005), where I'd like the user to see the structure what he/she make up with a TreeView like control. Just something like that when you explore your hard disk. How can I do that?
