Filling Text Boxes In A Loop On Another Form?
Jan 20, 2009
I have 100 text boxes on another form I have to populate. I don't want to use 100 Form3.txt1.Text = Mid(answer,1,1) as shown below, i would like to put them in a loop, like a For loop. But when I try I get Error1'txt' is not a member of 'WindowsApplication1.Form3'.Is there another way of doing this?

I am having a bit of a problem working with textboxes, subroutines, and modules.I have a form (frmMain) with 30+ textboxes. These textboxes collect data input by the user either manually or the user can choose to have the program randomize all the numbers in the textboxes by clicking a button. To randomize these numbers, I have a subroutine in the module called randomizeData(). The problem I am having is that the textboxes on frmMain are never actually updating themselves with the random numbers generated in the module. No errors or anything, but no results either. Here is a simple summary of what I have going on.
Public Class frmMain
Private Sub cbRandom_click()
randomizeData()
End Sub

Here i have code filling a drop down box with the company name.
Private Sub Filllistcomp()
listcomp.Items.Clear()
'define select statement
[CODE]...
This part works. The drop down menu is filled with all the company names. The following part does not work how ever.
Protected Sub listcomp_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) Handles listcomp.SelectedIndexChanged
'create the select statment that serches for a record
[CODE]...
There is no error thrown either. The information is just not showing up.

I am using a Class_SQL that gets the table, creates the DataAdapter and DataTable.I have a combobox named cboFullname. I can fill the combobox with data from the database, ie: Dim sqlcmdtext As String = "SELECT *, Firstname + ' ' + Surname AS Fullname From Contacts". I can display full records in a datagridview.
I would like to be able to select a name from the combobox and have the record text boxes display the data and be changed with the cbofullname index changed subroutine. Here is my current code to date:
Public Class frmMain Private Sub frmMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Is this possible? I have tried a few different methods with no luck. I am more of a JAVA person, but am taking some classes for VB, and have been playing around. This is what I have tried:
[Code]...
I think I'm going about this the wrong way, but would like to know if anyone has achieved this. All I'm doing is printing a simple character map to 255 labels, each label containing a char. Not an assignment, just having fun.

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 an insert statement which works fine but before the record is saved I want to validate the text boxes. So I just need to know how to check for empty text boxes before the save button is clicked on. I have seen a couple of examples like:
Dim ctr As TextBox
If ctr.Text = vbNullString Then
MsgBox("empty box")

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 do i do this in VS 2010?

I'm not 100% sure where to post this, as I'm making the program in VB.net, however It is linked to access and is getting the information / saving it into there.
I have a customers page and a jobsheet page,
the customers page is where the information on the customer is stored e.g. "Company" ,"First name" and "Last name".
When I Go into jobsheet, I have made it in so that company searches for the record from access so there is a list e.g. "Big W" , "Bunnings" etc, and tied up to the company is a name of the person in that company.
My question (after all the babble) is how can I make it so when I choose "Big W" from the list, it auto fills in the "First name" with 'John' and last name with 'Smith' , and if I choose Bunnings it uses the name associated with that and etc for the other companies.

experience on how to create an engine using C# (VB.NET is okay too) that is generic enough to handle most cases of MS Word text fields I need to fill with data I'm getting from a database? In short, I'm about to embark on this little Office automation excursion and I'm hoping a little bit of feedback here.

I've coded a Login form with two text boxes and two buttons goes to a Users database to validate the userid and password. When I click the OK button (button1) I get an error message on the highlighted line below(Dim Reader).
It states that no value is given for one or more required parameters. What parameters are they talking about?[code...]

The form has First Name, Last Name, Course and Email text box fields. First/Last Name must have no spaces, Course must consist of a three letters and two numbers in that order and nothing else(I want to avoid the use of masked text box), and Email must have the "@" sign and a dot. How would one make it so after clicking, say, Submit button and if there was a violation of any of the above rules then message box should pop up and tell the user which fields contain incorrect information.
Private Sub buttonAddNewStudent_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles buttonAddNewStudent.Click

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 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.

ive got code like the code below that creates textboxes dynamically. I want to be able to click a button and delete all of these textboxes i make, however im not sure how to do this. When i tell the program to remove the TBIndex control it does not do anything. The only way i get it to work is if i put the command in the same sub as this code. This code runs in a loop by the way.
So if the loop runs one time and creates the TBIndex control and i have a line of code right after to remove the textbox, then it does not show up on my form. But if i put the command in to remove the textboxes somewhere else and run the code the loop runs abunch of times and creates all teh textboxes and the loop is complete, then the remove control part is called and nothing happens. I just need a way to clear all the textboxes off my form with like a button. I also tried painting over the textboxes with a big grey rectangle but that dindt work.
TBIndex.Width = 54
TBIndex.Height = 20
TBIndex.Visible = True

I have a pop up form that contains a listbox. Right now I am telling it exactly which text boxes I want to be able to drag and drop to, but I was just told to have it drag and drop to every text box on the main form.The main form with the text boxes has a bunch of tabs on it that hold each section. Each section has text boxes, so how would I code it so they are all capable of allowing drag/drop without specifying each one separately?
This is the code from my pop up form:
vb
Private Sub txtDropIn_DragDrop(ByVal sender As Object, _ ByVal e As System.Windows.Forms.DragEventArgs) Dim DropInTextbox As TextBox = CType(sender, TextBox) Dim TextToDrop As String = CStr(e.Data.GetData(GetType(String))) 'get rid of leading " - " if there isn't 'anything in the textbox If String.IsNullOrEmpty(MainWin.TextBox1.Text) Then TextToDrop = TextToDrop.TrimStart(CChar(" -

I am making my first windows forms application in VS2010 and I am having trouble with arrays. I have code that dim's an array 'TabSiteInfo(2,20)' as a string. Then, I have a Loop that adds records to the array. The problem is that my array is not filling values from the loop. I know VS2010 handles arrays differently, but I have this same code working fine for me in VS2008 ASP.NET application. Below is a sample of the code.

I have successfully navigated to the page I want and now I need to know how to fill in text boxes on the page. I used SendKeys.Send before but that was when the first box was already selected. I can't seem to get the box selected by tabbing at all. I can find the textbox id if that helps.

I made a form with text boxes in a 6x6 square pattern. It will do a streamreader from a text file a number that indicates the size of the array. Then fill in the boxes with the numbers of the array. Then it will calculate the rows and columns to see if they add up to a single answer. Then it will display to an output window if it is a magic square or not. Meaning if all rows and columns add up to a single number its magic. If they dont add up to the same number then its not magic. Then it will repeat this check and output from the information of the other arrays from the text file.
I know how to code for the streamreader and get it to add the rows and columns. Im not sure about what code I need so it can check the answer if its magic or not and repeat it till the end.
Here are the contents of my text file which it will read from.

I have 81 text boxes on a form and would like to create a text array in code that will equate to these boxes on the form. Once I've assigned each text box from the form to the array entry, I'd just like to work with the array - then have the actual text boxes on the form reflect the changes made to the array.
