Clear The Information In The Text Boxes After The Button Has Been Clicked?
Jan 21, 2009
After I have entered data into 12 textboxes and pressed a button to execute the code, the data from the text boxes goes into a database.I want to clear the information in the text boxes after the button has been clicked, at the moment I have 12 lines of code which are similar to this.
MsgBox("Data Has been Added to The Database")
tbeventId.Clear()
tbtitle.Clear()
tbstartdate.Clear()
tbvenue.Clear()
is there a easier/simpler way to remove all data from the text boxes without using 13lines of code
I need to know how to clear what is currently in the combo box with a 'Clear' button. Basically, I have a combo box with a list of destinations for the user to choose from. Say the user selects Australia, when I click a clear button, I need this selection to disappear, and be ready for the next user to select a destination.
i am making a mini calculator and I have two problems with my current validation setup in the code. The code concerned is below:[code]Basically, I only want to allow numbers in the text box. When I enter a letter for example, the message comes up ok, but then when the box is clicked away, the rogue letter remains. Can someone tell me how to clear it properly?Also, when I use the backspace button in the box (pretend I want to change my input from 3 to 37), then the messagebox is prompted when I don't want it to be. I only want it to appear when a letter is entered.
1) How to I clear the banned characters from the text box after the message is clicked off
2) How do I get VB to ignore any backspace presses to prevent the messagebox from coming up.
I am trying to follow the book 'Sams teach yourself VB 2008'. It was going well until the end of hour 4. For exercise 1 I have created the form with a button and two text boxes, but cannot work out the code I need to move text between the two boxes. The Object Browser does not seem to help - am I reading it wrong?
I have a reset button created in my VB form, but don't know how to code it so that it will accomplish what I want. I want it to clear the form's text boxes so that new input can be entered. I could just code an end statement but this closes the form, and I want to keep it open to continue working with it.
I have a button that inserts data into a database.With that button I want it to serve two functions.One for insert and one for clearing the textboxes after the insert is done.I did a little bit of digging around and her is a code snippet that i found online:
Dim ctrl As Control For Each ctrl In Me.Controls If TypeOf ctrl Is TextBox Then ctrl.Text = ""
I need to trigger an event (clear some text boxes) when I click on the "ok" button in the MessageBox. Below is the event triggered messagebox code. A box pops up with the included text and an "OK" button. The program appears at this point to stop and wait for the click on "OK" MessageBox.Show("Check -Sender Information-data")
I have a group box with 4 radio buttons and another groupbox with 4 text boxes.how do i write a short code to clear all text boxes and radio buttons within each box.i have written code the long way, ie..[code]but i think there is and easier way but i cannot find the statement.
I have a text file containing 10 pieces of information. I want to read the information from the text file and put it in text boxes on a form, so that the user can view the information and edit if required. What is the best way of approaching this?
I am receiving information via a serial port as Integers. The information is the displayed on textboxes(two text boxes). My problem is that, I am failing to transfer this information to a Datagridview.I have written the following code.
Private Sub BtnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnSave.Click TxtDuration.Clear()
I know how to load a txt file into a single text box, but im having trouble loading a text file with multiple output information into multiple text boxes using commas to separate the information.
I think the problem arose because of Windows 7, but when I was at school the program worked. The program fills in the text boxes with information from Microsoft Access. However, my laptop has Windows 7, and when debugged, the information doesn't fill in the text boxes like before. Also, for added information, the school's computers run with Windows XP.
Basically my program creates a text file based on whatever is contained in the 6 list boxes. What i need it to do is load the text it created back into the relevant list box. text file looks like...
Consignment Number-----Shippment Method------Expected Departure Date CC33-1EA------------Express Air-----------18/05/2010
I want to pull information from an array and place it into a chart of text boxes on the form. I have used a control array before but this time I want to create a dwo dimension control array. My guessing is not working... The display will be 10 x 10?
I have a problem in that I have five text boxes pertaining to a customer/client, where there is a txtbox for each: Name; Address; City: State; Zipcode. Of course all the txtboxes are "" at initialization. I also have 2 combo boxes and a 2D array for prices which I have finally been able to understand the array logic. I have also been able to do my necessary calculations for.
My problem. The customer information is first to be validated as all being strings and not empty. The combo boxes I was able to get to tie to my 2 dimentional array and get good output and calculations for a finished product. I am just having problems with the error messages. Also I don't want summary totals unless the data is valid. In other words, the user must enter a complete address and make decisions about the two combo boxes, both of which are needed to use the price array. I will change the comboBoxes to represent dress sizes,"S" "M" "L" and "XL" and the other combobox to describe colorRedSatin or colorBlackBroadcloth with a two dollar difference in price between them. 'That would be similar enough to the problem I need to solve.
Basically I do not want any numbers to appear for price of the dress or addons to the dress unless all validation is complete. I do understand how the radio objects work for discounts and check boxes for accumulating accessories. The program should not give any totals untill the user has input all customer information and made decisions about input from combo boxes and selected calculate from menu. Right now it calculates and puts zeros in when choices are not made from the combo boxes by the user. It will include correct amounts for radio buttons and checkboxes if anything is entered. I need error messages for customer inputs and combo box inputs (if not selected from list of option in drop down for choices) (basically if nothing was put in a text box, the text box is empty. Of course the problem is the user must enter something in all 5 textboxes and not get multiple error messages in rapid succession to fix. We can't always count on our users putting in good data.. When I tried a Do While False with ORs I was getting endless looping. I could not get it to work because it will never execute because the control never passes back to the user.
I don't want to list a series of If/Thens becauser the user will see about 7 messages, where he/she only needs to be fed one at the time. I hope someone can give me some direction. I just need guidance on how to validate the text boxes and combo boxes. The code is analyzed with a "Calculate" on the menustrip. I would like for the calculation not to calculate and put outputs into the summery text boxes unless all textboxes are filled and combo boxes are valid for all the customer information and combo box choices for my two combo boxes describing what is needed for the order to calculate. There are also the radiobuttons and checkboxes, DIMs, Const, Variables, but not having problems with that part I have my indexing problems on the combo boxes worked out also, so I am not concerned about those now except for getting the error messages when I should. I hope that I have described my issues fully. I am using visual studio 8 with Windows 7
I want a button that can clear all the text in, for example: If the button1 (which is the clear button) is named clear, I click it, would the code be something like button1.clearalltext = True?
I have code which saves DGV contents including check box columns as a comma separated text file. I also have correct code which will take the text file and re-insert it into the DGV at a later time. This all works.When I'm working on the DGV, I have this
Private Sub DataGridView1_CellValueChanged(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellValueChanged If DataGridView1.Columns(e.ColumnIndex).Name = "Column12" Then[code]....
So that when the check box is true, columns 1 and 3 turn different colours, and when false, go to a yellow colour.However, when I "re-insert" my DGV info from my text file, the check boxes come back correctly - as true and false on the right rows - but columns 1 and 3 don't change colour. I've tried a "DataGridView1.Refresh" option but not getting it to work.The DGV is unbound. I need it to recognise which check boxes are true and update automatically when the information is opened from a text file.
I am confused about how to make a button able to clear the text in all textboxes. I know in c# I can just say textbox1.Clear(); but this won't work in this case.
how would i go about changing the text property of a button when clicked. Im using panels to switch between what the form shows but when i click the button to switch panels i want the text of the button to change but i cant figure out what property to change and how to go about doing it.
I am trying to have a textbox format a string entered on the click of a button.I have 4 text boxes, each of them represents a time in / time out.I need to be able to enter
box 1 - 345
box 2 - 400
when the button is clicked it changes that to 3:45 and 4:00.all my attempts to use the Format in VB has failed.
form1 have four buttons, i want to set a label text in form2 according to which of the button on form1 is clicked.below is what i tried so far.on form1 each of the button click event i made it focus
Private Sub Answerbtn3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Answerbtn3.Click Me.Focus() Form2.Show()
and on form 2 load event i have
Private Sub FinalAnswer_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load If Main1.Answerbtn1.Focus Then Label2.Text = "You choosed option '
[code]....
the above code displays only the first condition ("You choosed option 'A'"") on the label when any of the button is clicked?
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.
I am here by to ask help on enhancing messageboxs. How is the way to Display a picture(like a JPG file) inside a messagebox along with text when a button is clicked?
I'm trying to do is make a program to where when you click an option, a text outputs for each button clicked, the general design looks like this:
That's just a beginning, since the whole rest of the thing will be the same concept pretty much, and what I want to have it do is, like stated earlier, once the option is chosen, a text output, like this:
I know there is an alternative to solving that, but it will take me 10x more time, and that is, creating a new textbox, setting the visibility to False, and typing what I want outputted in that text box, then putting: RichTextBox1 = TextBox1.Text
I know that works, and gives me my output, but I just wanted to know if there was any other way but that.
I need help getting the sum of a bunch of text boxes into another text box without using a button. Ive tried using TxtTotal = Val(txt1) + Val(txt2)... in the Total1_TextChanged but nothing happens. Someone once said I should use databinding but I cant see how that would work when Im using user input as the data to be Totaled. Also I dont know a whole lot about vb as I am just learning, and databinding
ps the values Im adding are in currency format. So I guess i would need to convert them back to add them, but im not sure.
