I am using many text boxes in a form. How do i validate them, In certain text boxes I have to use only text and in some I have to use only numbers. Is using ASCII is a right method or is there any easier method to do this. If so please let me know the coding.

The Object Browser does not seem to help - am I reading it wrong?
View 14 RepliesI am starting out in Visual Basic.Net and need a bit of assistance.I am creating a Windows form (not controls).In this program, I am attempting to validate 2 different text boxes BEFORE the rest of the controls can be validated. For example:I have an authorTextBox and titleTextBox, which the authorTextBox MUST have some user input BEFORE the user is permitted to move onto the titleTextBox. (the user input can be fake like "John Doe", the point is to force the user to input something).The instructions that I was given is not very clear on how to code this properly in order to have the form show an error message requiring the user to input something in both textboxes before they are permitted to move onto the other controls.

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).

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.

I have this function which evaluates the contents of a textbox (or combobox or maskedtextbox) control and, in conjunction with a KeyPress event, will either allow or disallow the input. It is quite useful for dates or textboxes for which only numeric input is valid. It allows a set number of digits after a single decimal point, if specified in the function call. It also allows the backspace character if the textbox is full.
I would like it to allow me to input what would otherwise be valid text when the textbox is full but one or more characters are highlighted (and would therefore be replaced by the keypress character.

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.
View 6 Repliesive 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 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.
View 4 RepliesI 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.

View 1 RepliesI need to create a form with radio buttons, text boxes, labels, etc.. This information needs to be pulled from a database. For instance, I have a form that displays information that needs to be inputed to a database, based on what test is being done for a specific product. Each product requires different tests. So each product may or may not have the same information that needs to be inputed..
What I have done is made a database and filled a table with each product and what tests apply. I then call that database after the product has been selected for the tests. It will then fill an array for that products information for what texts boxes and labels need to be shown. I wanna take this further and have it create a form through code and align all the controls to specific spots so that it will look nice. For example I wouldn't wanna create a control and have it be cut out of the form, or have other controls overlapping others.

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

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.
