Im new to VB and therefore i require some guidance in this tricky situation that im stuck in.Basically, what my program does is calculate the mach number of an aircraft when the speed of sound and value of temperature are added into the text box. The problem arises in 2 places. One, the program calculates the value of speed wrongly. And secondly (The major part) is that i want the program to display an error that i should enter both the values (that is, if only one value is entered and calculate button is pressed.)and if i enter any alphabets, it should give an error to please input numbers.
i have 2 forms.in form1: i have 1 combobox in form2: i have 1 textbox and 1 button...I want to make in form2 when i enter some text in the textbox and press the button the text to be added in form1 combobox
I have one combobox, two buttons (Add and View) and listbox. When I click button Add text from combobox is added to text file. This is code for Add button:
so i made a from with in it a WebBrowser now i added a Toolstripmenu and added some text in the toolstripmenu how can i make it that when i click in the toolstrip menu to go to an web browser
Private Sub World30ToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles World30ToolStripMenuItem.Click End Sub
i thought it was something like call webbrowser but it didnt work out
I have a form that users record some event that is happening. They enter in what different things are occurring, for instance like a Basketball game. When certain events happen "steal", "score", "foul" these will get inputted to a listbox that records the whole game and is timestamped. However for these specific event i want them BOLD . So it would look something like
3:24 STEAL 3:25 #45 stole the ball, passed to #54
Or something like that. How do i get certain items to be bold?
I have a series of text boxes on my form, and my client wants me to filter out characters that aren't allowed, for example in the name field you cannot have symbols or numbers.
Now, he wants it so when you try and put in a special character it simply will not get entered into the text box. I know the logistics to this, but I'm not sure how I would go about coding it.
Basically what needs to happen is when the user types in characters like $, ^, 5, * etc, a function needs to recognise this and stop them from being entered into the textbox, whether it means deleting them as soon as they go in or interrupting the action altogether.
I have a program that adds controls on the fly to an auto-scroll panel. When the panel is scrolled (viewing the bottom of the panel for example) and a control is added, it looks like it is added assuming the top left corner of the panel is still at 0,0 when in fact it may be 0,500. To see what I am talking about, create an empty "Windows Forms Application" project and insert the below code into it.
Friend WithEvents Panel1 As System.Windows.Forms.Panel Friend WithEvents btnAdd As System.Windows.Forms.Button Dim ButtonCount As Integer
I've added some Labels to a form at runtime using this
vb.net Dim x As Integer = 25 For i As Integer = 1 To word.Length
[Code]....
Now, I would like to add text to one of them, but I'm not sure how. I thought by setting .Name I would simply be able to write something like lbl4.text ="A". But, of course, because the Label has not been created yet, this is not possible.
Also, I'm not even sure if .Name is working the way I think it is. I was hoping that it would name each Label consecutively: lbl1, lbl2, lbl3, lbl4...etc.
Am I naming the Labels properly? And how would I add text to one of these Labels?
i have multiple forms in a project and all have statusbar. there is no way to add textbox on status bar but in my previous thread i got the help to add the text box. i created a function in module so that i call that function from all the forms on load and add the textbox on status bar and also add the event on textchange. the function to be called on event change is in individual form (at present)[code]
I have a form with a text box and a form with a list box. I would like to be able to push a button on the form with the text box and have it be added to a list box.
I am adding controls to a page programatically in the code behind. I add an asp:Label and set it's Text value. I add an asp:TextBox and set it's Text value. Both Text values are returned in the Response and displayed in the browser. All fine so far.
The user performs an action that causes a postback. I re-load the dynamically added asp:Label and asp:TextBox. When the Response is returned to the browser, only the asp:TextBox Text value is displayed. The asp:Label Text value is not. If I inspect the HTML I can see the asp:Label control (rendered as an HTML span tag) but no value.
How can I get the code to automatically re-load the Text value of an asp:Label on each postback? Why is the behaviour different for an asp:Label and an asp:TextBox? I do not want to have to manually re-set the Text value on each postback.
Here is some code similar to what I am doing (placeHolderNameplates is an asp:PlaceHolder control on the aspx page): Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init If Not Page.IsPostBack Then
My app has text boxes to accept input from user to questions shown on labels. When the user input is valid, a literal is added to a string incorporating the user input. If the user doesn't input anything or if user inputs "no" or "None" I want the literal and the user input to not add to my string. Make any sense? See my code below:
i like to get CPU temperature of my own machine and i am developing application for network monitoring. is there any way to get CPU temperature using Visual Basic..
I have a datatable property called prpParametersTable in a class called clsBatch. I have a procedure that sets a datatable variable called dtP equal to prpParametersTable at the beginning of the procedure. I then add three new columns to dtP.Here is my problem. When I add the three new columns to dtP my original table prpParametersTable also gets those columns added to it, why? I only want to add the three columns to dtP and not prpParametersTable. How can I do that?
Private Function prvfnc_InsertBatchParameters(ByRef cnn As SqlConnection, ByRef trans As SqlTransaction) As String ' set new columns that have BatchID, Insert DateTime, and UserID for the SQLBulkCopy method below Dim clm As DataColumn Dim dtP As DataTable = clsBatch.prpParametersTable
Recently ive been experiencing someproblems playing minecraft on my toshiba qosmio x500, because of the high ram and cpu useage, my laptop gets very hot very fast, simply turning off due to overheating after maybe 20 minutes, if i am not rasing it off the desk, in which case, i must be careful as the fans are often blocked by whatever i am leaning the laptop against, otherwise if positioned carefully, i get cpu heat at a constant 90% or so,100% being when the computer overheats and turns off.[code]...
I just searched a method to read my CPU Temperature, at first i tried W32_TemperatureProbe, but this didn't work. Now i use: MSAcpi_ThermalZoneTemperatureI found this [Code]
read the cpu temperature in a VB application.i tried to get it using WMI but that isn't supported by my computer.i used code i found on this forum and what i get from the WMI code creator.this is the code created with the WMI code creato
So far, my friend has this, and we're trying to figure out how to get the code to tell convert F to C, and back. All we can use for input is (example:) 10,f and it will change it to 40,C.
I'm doing a little app that basically has 2 text boxes. You'll enter Fahrenheit into TextBoxA and Celsius into TextBoxB.As the text changes in TextBoxA I want the equivalent Celsius value to be displayed in TextBoxB and vice versa.Is there a way to do it all in Xaml except for a Convert class that does the maths? So basically I want the TextChanged event of one textBox to pass in it's value into a Converter class that is evaluated and sent to the other TextBox and visa versa.
im wish to get the cpu temperature and cpu fan using wmi.. in my bios, i can read my fan speed and cpu temperature.. i tried to use wmi to get the data but it doesnt function..for the wmi, i downloaded the wmi creator from microsoft website.. n it work perfectly to find other information like bios infomtion. however, it is not working with cpu temperature and fan speed..from internet, i found a program called SPEEDFAN and this program can list out all the computer temperature... do anyone know how this program function? i wish to get the information of temperature using vb.net.
I'm trying to get hard drive temperature data.I can get the temperature via MSStoragedriver_ATAPISmartData.And, I can get all sorts of drive info (model, serial #, etc. via the Win32PhysicalMediaClass.The trouble is trying to link the two together.I get this temperature info, but I don't know which drive it is.The only identifier I can get from MSStoragedriver_ATAPISmartData is InstanceName.That looks like it has the model number embedded in it, but I can't get model number in Win32 my question is how can I get the temperature data and realte it to a specific drive?
I am able to get a list of my drives by using Dim allDrives() As DriveInfo = DriveInfo.GetDrives()
Now I am wanting to get the current temperature of the drive. My total code below, everything is wrote to a ini file for pickup of another program I use on my network. Dim allDrives() As DriveInfo = DriveInfo.GetDrives() Dim computerN As String Dim path As String computerN = Environment.MachineName 'set computer name [Code] ......
