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.
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?
The code below shows adding three text boxes using a button, I'm thinking when there's excess of text boxes that has been added, how can I delete the excess using another button.[code]...
I want make VB program that has two text boxes and one button. Text boxes are for Proxy server IP and port. And button is just confirming it. So, user just types in Proxy server IP and port and presses button, and now, when he go to internet, he is anonymous. Now, I need code that sets proxy on after button click.
I want to have 5 numbers randomly selected from 500.I've set up the form with five text boxes and a button but I have no idea how, when the button is pressed, to get five random numbers to appear in each of the five text boxes.
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 have a hidden web browser, two text boxes, and a button. I can add the login information to the forms on the web page, but how do I login? Heres my code so far
[Code]....
Basically I want to grab the ID of the sign in button (the name/id is SI) and click it. I've tried RaiseEvent(Click) and Click() but neither work...I'm not sure about the syntax and how it works in general....I don't even know if I'm doing it right.
I am wondering is there an easy way to fill up text boxes. Lets say, i have a form with 11 text boxes. User puts a decimal number in one text box, hits button and that decimal number becomes converted to binary and i need to fill up all 10 other textboxes with elements of that binary code. My code looks like that:
Dim a As Integer Dim s As String Dim aa() As String
In a program I'm planning to generate reports which I'll display using the rich text boxBesides rich text, i want to put images into the rtb. I've looked up how to put images into rtbs and the only way that i can find seems to be by pasting them from the clipboardThis method works well with setting bitmaps to the clipboard but i run into a problem when i try to set a metafile to the clipboard (the report contains plots and metafiles are perfect for that kind of thing). So if there could be another way of inserting a metafile into a rtb or maybe a way to write a rtf file with a metafile in it, that would be great.
I want to display (DataGridView's) selected row contents (each cell value on appropriate text box) on text boxes on the form. This should be fairly simple task for experienced i am sure.So far i haven't been able to find a single working solution to accomplish that as most of the articles are written for VB / VB 2005/ VB 2008 and not VB 2010.
Here is what i have already tried. (I tried putting an image but i can't due to my privileges over flow) TextBox1.Text =DoctorsDataGridView.CurrentRow.Cells(0).Value.ToString It strangely works for first 4 selected rows and populate text boxes but fails for the rest of the DataGridView.
I'm writing a program for my class, which pretty much is an energy cost calculator. It takes 4 inputs from 4 text boxes and multiplies them, and the result is the cost. Well, now I have to come up with a way to check for empty text boxes and display a prompt to enter a number. I've tried inserting multiple codes to display a prompt and to no avail nothing has worked, I also receive the error "when casting from a number, the value must be a number less than infinity" error.
I need to compare the data between two text boxes and a variable. If the value of the boxes don't match up and the variable is -1, I need to fail it.When I do this:
VB.NET If Not Me.txtPcidSystem.Text = Me.txtPcidDatabase.Text Then
I have no troubles, but adding the variable check produces a false positive.
VB.NET If Not Me.txtPcidSystem.Text = Me.txtPcidDatabase.Text And TestData.BypassCheck_PCID = -1 Then
The way the code is laid out, I have to do this in one line. I can't check the first condition on one line and the second on another.I've tried separating the data out with parantheses, but it's producing the same results.
so i have this data grid, which i wanna search , base on specific criteria from two or more text boxes; eg a user wants to search employees from karachi, so they enter karachi in the first text box. now they want to search employees from karachi whose status is permanent, so they enter permanent in the second text box, and the data grid shows employees from karachi whose status is permanent.
For search from ONE text box, i have used the following code :
Private Sub TextBox1_KeyUp(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.KeyUp If TextBox1.Enabled = True Then

im no champ at vb, i just started some 7 days ago for my computer project, so ill really need to be spoon fed the details :|
I have three Columns of text boxes and I need each column to be added up and displayed in a text box directly below each column with out using a button. The program is a cash counter I already have the code done for multiplying, for example txt1.text = txt2.text * 0.01 (not the exact code) anyway the totals from these is displayed in the columns I was speaking of. I tried the same method I used for multipling but that doesn't work.
Public Sub RandomNumbers() Dim s(4) As String Dim RandomNumber As Byte
I don't know if you can tell what I am trying to do here, so I will try to explain. I what to create for random numbers and place them into for different text boxes. I also would like to do this with combo boxes and their selected indexes. So if the combo box has 10 items in it; the new selected index would be the random number generated above.
I'm in the middle of creating an application that will be used to input customer information whilst the customer is speaking to someone over the phone. This involves the customer giving the employee information such as name, address, postcode etc and the employee inputting that information into text boxes and combo boxes that are in the application.
What I would like to be able to do is after the customers information is given over the phone, I need to be able to send that information to a database which will probably most likely be done by button click. In this case, I'm using Microsoft Access. I'm also hoping that I can do this within Visual Basic coding.
The database is set out with multiple tables which include a customer table and a ticket table and both have multiple fields such as first name, surname in the customers table. Both of these tables are in use with the information that the customer gives over the phone.
I've already asked on other forums and people are where replying giving me third party programs that I could use to implement this, something I don't really want to do.

Im trying to make a program that allows the user to view additional information via moving the cursor over the label to view (make visble) additional information, in the form of text boxes and/or picture boxes. How will i go about doing this?
In VB10/win forms project, when I change the forms font size the form and all the controls on the form get larger or smaller, OK great! The problem is the combo boxes then appear with their text highlighted. Is this a bug or am I doing something wrong, simple example..
I'm trying to lern VS 2010 from VB 6 and one of the things i'm hawing a problem whid is control array.In vb 6 if you create a text box it's named "Text1" and if you yust copy it and paste it it renames to "Text1(0)" and the new one's name is "Text1(0)" and the code would lock like this
[code]...
then it would print for each loop the random result in one of the text boxes corresponding to i.
how to move info from text boxes on one form to binding source text boxes on another form. I am displaying array info in text boxes on one form and i need to add them to the database on another form. How do I do that?
I'd like to know if it's possible to, for example, place a small 32x32 icon on the left hand side of a Button control and offset the text to the right to make room for it. I know it's got to be possible, I'm wondering how easily done it would be though. Would I have to derive a custom control and then handle the drawing myself?
The user will be selecting a file to be read into the program. At the top of the form is a button that says "View Hourly Data File". This button is to be a link to open the data file in a text viewer. However, I would like the button to be deactivated (grayed out) until the user selects the file. Once the file is selected, it will then be an active button.
The Second:Once the user selects the file, and the button is activated, I want the user to be able to open and view-only the text file that they have loaded. It should be opening into a pop-up window.
I've been writing a weight program for flooded pressure vessels and I'm having trouble retrieving the data from the text files I've been saving. I know how to write the data to the text file, but retrieving it with OpenFileDialog is not so easy for me.The user has individual text boxes that they input strings or numbers into and when they save the file, each text box input is written to one line in the text file. For example, the first text box is for the username, therefore the first line of text that is saved is the person's name, the second text box is the customer, thus the second line in the text file is the customer name, and so on.
(Actually, the first line of text in the saved file designates whether English units were used or Metric units because when the user retrieves the saved file, English units will open one form and Metric units will open a separate form, so some If...Then statement will need to occur).I need to be able to read the first line, have either my "EnglishForm"form open or my "MetricForm" form open, and then have each subsequent line of text be displayed in their corresponding text boxes. I know I need to use ReadLine or LineInput, but I don't have a clue what to do.Assuming the syntax I've displayed below would just magically work (if only life were that easy), it would look something like this
If FirstLineOfTextInFile = "English" Then EnglishForm.Show() ElseIf FirstLineOfTextInFile = "Metric" Then[code]....
And so on...I read a lot of articles from the MSDN library and exhausted each link that I've looked through from Google and Bing, but most only retrieve data from the file to a single text box through some loop or streamreader and don't take into account multiple forms.
i am trying to automatically generate multiple text boxes on a form with the following code
Private Sub CreateTB(ByVal x As Integer) Dim y As Integer = 1 Do Until y = x
[Code]...
i need it to generate as many text boxes as the variable x states, so i used the do until loop thing. But i am stuck when it comes to naming the text boxes because obviously all the text boxes cannot share the same name. so i would like to know how to programmatically name each textbox uniquely.
I want to split each line at the comma and write the left side to a textbox and the the right side to another textbox. I'm close, with the code below, but I can only post results from the first line in the file. How do I loop this and append the text results in each of the textboxes.
Dim TempFile As String TempFile = "temp.txt" Dim sw As StreamWriter
