View 1 RepliesPart of my assignment is to check if input to Group Number and Number of Units are correct input by making error handling exceptions...
I have to check the following:
a) group number is neither 501 nor 062
b) number of units are NOT numbers
c) number of units is NOT a positive number
So my first question is, am I checking correctly? 2nd question is, How do I make sure my Exceptions will pertain to their correct respective things (a, b, and c.. above)?

I am trying to draw textboxes when the user enters the amount of textboxes to be drawn on one form and the textboxes get displayed on the another form. I have found these codes online but it works with inbuilt codes I guess. That is, the number is already hard coded in the form.

I was about to create a program about CPU Scheduling (SJF Nonpreemptive), Now, I want to ask the user to input the no. of processes ,then based from the user's input I would display exact no. of text boxes where the user could enter the value for each process then store it in an array. But I don't know how to code the text box., I'm new to VB.net and I'm used to it's 'drag and drop' nature. I just want to know how the code to output this text boxes. and is it possible to have an array of text boxes?
BtW I'm thinking of using 2 forms here
Form 1 for the USER INPUT OF THE NO. OF PROCESSES
Form 2 for the output of TEXT BOXES
I'am creating a program that will input a number in a textbox for example 5 and display 5 textboxes in form...I have no idea how to do this but here is the code i've done..
textbox1.text = val(textbox1.text)
'i don't know what to do next..
how to do array of textboxes when a user input a number of textbox to be loaded and when the button clicked, the array of textbox that the user enters will appear?
View 1 RepliesI have two text boxes on my form. text box 1 allows a user to type in a number (decimal) and text box 2 will display the smallest number typed in so far. The idea is to find the smallest number typed in by the user in text box 1, by using the Math.min method to compare each number typed in by the user to a variable that contains the smallest number to the point. Then replace the variable value with the smaller of the two numbers. To make it work for the first number. I have to initialize the variable to 99999. (no if else statements should be used).
View 3 RepliesIs there a simple way to save user input from MANY controls (textboxes, comboboxes, etc...) to a text file? When I say 'MANY', I am referring to at least 580 textboxes and several dozen comboboxes.
I may be able to accomplish this using the StreamWriter Class, but doing this individually would take quite a long time. I suppose I could also change all text boxes to richTextBoxes and save to .rtf. It seems like this would be even more time consuming.
Surely there is a simpler way to do this 'globally', perhaps with an added single line of code that points (and saves) to a preset or created text.txt file whenever text is added or changed in a textbox or combobox throughout the program.
I'm trying to do a project which involves reading the text from a number of textboxes and putting it into a string.I'm just wondering if there's an easier way to it other than:
CreateString += TextBox1.Text + TextBox2.Text + TextBox3.Text... (etc)
I have thought about creating a For Next loop which would go something like:
For i As Integer = 0 To intNoTextBoxes
CreateString += TextBox(i).Text
Next
But this really doesn't work. I also found something saying that something similar to this would work:
For i As Integer = 0 To intNoTextBoxes
CreateString += Me.Controls.Item("TextBox" & i.ToString).Text
Next
But that didn't work either.
I am trying to bind a textbox to a binding source (using the IDE DataBindings Editor) and it works fine except for one thing: if I delete the text I get the subject error. What I want to happen is the datarecord field be updated to a dbnull value -- how do I get that to happen?

I have an existing database that I want to add a number to that the user inputs. So lets say that in the database there is 4 carrots, and the user on the addinventoryform inputs 3 carrots and pushes a button. Now I want that number to be added to the database number so in the database there would now be seven carrots. I am using an oledb connection and cannot figure this out.

How do i get data from a database and put it in to multiple text boxes?Basically i have abilling form with; name, address, etc.But i have a 'retrieve' function underneath which allows a name and post code to be entered and then the information above is automatically filled in if the name and post code exists. At the moment i just setup a connection with the variables. not sure how to do the rest
objCommand.Connection = objConnect
objCommand.CommandType = Data.CommandType.Text
objCommand.CommandText = "SELECT CustomerName FROM Customer WHERE CustomerName = @CustomerName AND PostCode = @PostCode"

I am trying to save new data every time and then I have to edit it or load it. here is a screenshot you might get some idea by looking at this:
First I will input data (in all textboxes) using create button which will be stored then If I want to edit any thing I will input only the part number and press search. the stored data will come up. I will edit it and update it (Load button is update). Now I can save it in txt file and load it using regex but the problem is edit. I can not edit. If i create a database I cannot save 100 parts (or may be more) in one database so it might create too many db files. So is there any other option I can save parts detail then load it and edit it without create so many dbs?
I am wondering if it is possible to take a string, split it at a certain character and then put the 2 parts in different text boxes.
For example:
String: PCNAME%Message
Textbox1: PCNAME
Textbox2: Message
this application I'm writing is for Employee Data. I have 7 texboxes and 1 combo box.With the file menu I have used that function to save info inputed in one texbox. However for this application I need to use btnSave button to save the record.

Dim result As DialogResult

.Title = "Find Input File"

How can I implement this with a button?
How do I validate textboxes so that they accept only numerical input (1 2 3 etc and not abc @$ etc)? Is there some kind of property of the textbox that I have to change?
View 1 RepliesI have a web page with 5 checkboxes and 2 textboxes per checkbox. When the user checks one or more checkboxes the corresponding textboxes become enalbed for UI. I need to insure that the input for the textboxes is an integer-that I will do with a validators. There is a gridView on the same page. When the user checks one or more checkboxes the 2 columns of the gridView rows become active for input through enabled textboxes.
There are 4 columns in the grid. The minimum number of rows enabled are 2 and the maximum are 26. The UI for the grid's textbox input is numbers. Those numbers have to be equal to or less than the total. How do I validate UI of numbers(integers) into the grid's dynamically generated textboxes and then add the total and compare it to the alloted total? I prefer to do this with the code behind - using VB.NET - rather than with ASP.NET or absolutely not javascript.
What I'm trying to do is make a list of members in a read only textbox getting the data from two textboxes (first and last name) and a 'save' button. I've made a class named 'Deltaker' (Members in english) to store data and a list 'resultater' (eng: results) using the 'Deltaker' class. I'm trying to get user input from two textboxes 'tbxFornavn' and 'tbxEtternavn' and I use my class' public function 'Navn' to display it in the textbox 'tbxHistory'.

I'm trying to get user input from two textboxes 'tbxFornavn' and 'tbxEtternavn' and I use my class' public function 'Navn' to display it in the textbox 'tbxHistory'.
I've got a sub procedure to add the input to the list and clear the textboxes and enable another reset button.
So for the save button click event I run the sub procedure and I've written a for next loop to display the results from the list. The first name I enter is all good, but with the second name entry both the first and the second name gets listed as well as the first name that is already there. I thought about using the .clear function to clear the list after each input, but I also want to incorporate laptimes in the list and display the best time in a lable at the bottom of the form. Maybe also sort the list, so I need the data in the list to stay intact.

I am using Strongly Typed Dataset for my project which is created as a dll for DAL(Data Access Layer)
I have added the Sql Server Table into this dataset using the designer and has created a DataAdapter[code]...
I cannot find how to display an error message when what I typed in the listbox field is not in the listbox collection.
For example the listbox contains the following items
1) Apple
2) Strawberry
3) Mango
If for example I type "Mongo" and then press tab to another field, a message will pop up saying I typed something not in the listbox. Anyone who knows how to code if text in textbox1 is not in listbox then blah blah blah.
