VS 2005 : Force User To Input Value?
Oct 26, 2010
creating code to force user at runtime to place values in textboxes. This is what I have so far. I want to be able to force the user to have to place a value in the empty textbox and change the backcolor of the textbox back to default color after a value is placed.
HTML
Public Sub Subjectvalues()
Dim SubjectValues As TextBox() = {Me.subj_ba_txt, Me.subj_bed_txt, Me.subj_dom_txt, Me.subj_gla_txt, Me.subj_levels_txt, Me.subj_lotsize_txt, Me.subj_lp_txt, Me.subj_orglp_txt}
Dim tb As TextBox

I'm attempting to learn VB in college. My first project is to create a program in Small Basic and then write it in Visual Basic. I'm looking for the equivalent of TextWindow.ReadNumber() from Small Basic in Visual Basic. I want to force the user to input a number not letters. I'm writing this program for the Console. Is this possible? During my testing I entered a word instead of numbers and the program crashed.

I have a text box labled QTY, which feeds the QTY column on a datatable. the table then is ran through a function that takes the data and converts it to a string which my production machine can read. My problem is this, and its probably really simple (these problems usually are) how to i force the user to use a specific type of input on the txtbox so they would have to put the QTY in the format of 01 02 03 etc etc, i have it set to default to 00 but i want to force the user to haver to input 2 chars.

I wanted to have a textbox that can be input in terms of numbers. Then I need to use the number user input into a certain equation. How I can do this??
Also if I want a user to input equation such as A+B into the box, but then I need to use the equation user input to find answer for certain A and B value. Can this be done?

have a web form using Asp.net 2.0 with vb.net. I have two date fields on the form but I would like to validate them before my gridview uses them as parameters. I am using a Dataset for the source of the gridview and two parameters called StartDate and EndDate.
Basically in the code I am setting the values of the fields to the current date at runtime. Also the date fields in the SQL Server table are datetime and I only want the user to have to enter the date and it would grab all records within that date range regardless of the time. When the user enters the two dates and clicks a button on the form I need it to reset the parameters to the enter dates and refresh the data.
Here is the
Partial Class DispatchRequestList
Inherits System.Web.UI.Page

If my Category and Forum selection is incorrect I am sorry and feel free to move it. I'd like to have the users input in the message box that will show. For example: There is a textbox and the user puts in their name as Bob. Then the message box would be: What my main goal is, is being able to include the users input they type inside the textbox inside the message box.

I'm programming a Minesweeper clone in Visual Studio 2010, with VB.NET, as a Windows Form Application, and I'm having trouble with the Game Won and Game Lost forms. When I show those forms, I want the game form to still be visible, so that the player can see where the mines were, but I don't want the game form to be enabled until the Game Won or Game Lost form is closed. Exactly like Windows Minesweeper does when you win or lose.

I've tried searching and haven't found much useful information on this, I know it has to be possible, but I'm not sure how. I've got an application that bi-directionally syncs with an SQL express 2008 server. right now, I've got a hardcoded sa user in my conection string, however one feature that was asked for was to audit every change made by end users into the database. To implement this, I've created a user login and password for each user that is going to use my app (8 of them) on my sql server, however I now need to change the connection string to include each users name in the string. This is what I've got setup so far:

this maybe an easy one for mos of you! I have a windows that is displayed as full screenThe window contains a series of images (movie posters) and the name below it. When you user clicks on a movie poster a new window appears (smaller window) in the middle of the screen.I want to force the user to close close on the small window before procedding. Currently if the user clicks outside the small window the full screen window comes to the front thus hiding the smaller window.

I cannot figure out how to incorporate the number of days into the input box then get it to loop and count the number of times the User inputs in the number of days. Then I have to incorporate it into the equation to get the total distance D = MPH * Hours. What I have right now wil not count up the number of days and locks up after I input one number and will not add anything to the listbox. Because I also have to make sure that they cant add nonnumaric values and the number of hours per day cannot exceed 20. I have put things in and taken them out but it has been 2 days and I am lost now

In VB6 if you do this,
keyStr = Left$(baseKey + encPassword, 56)
the string will be 56 characters even if it means appending whitespaces to the end.
in VB.NET
keyStr = Left$(baseKey + encPassword, 56)
will not necessarily be 56 characters. How can I force it to append whitespaces at the end if the baseKey + encPassword is less than 56 characters long?

I would like to try and implement a feature wherby once you have logged into an application (straightforward winforms application) and had your credetials verified the application would then force you to log on again if no activity had been detected in the application for a certain number of minutes. In essence I want to provide some extra security for those occasions when users get up and wander away from their machines for prolonged periods.
I have all the logic for logging into the application, it's just the checking for no activity over a given period and then forcing the user to log back in again that I'm not having much luck with.

I want to create a simple form with 2 buttons, one to end the program and one to log the user off, I have done this successfully and have everything looking and working as it should. However, I want to force the user to pick one of these buttons before using the machine, my idea was to trap the mouse in the form so the only thing the user can do is select a button. My question is how can I do this?

I have to select checkboxes besed on group column values. If you see below gridview, column 3 (GroupNo) has 1,1,1,1,2,2,2,2....etc (this column data is not static, will change based on page index. i.e PageIndex =2 may starts with 7,7,7,8,8,8,8,8,9,9,9 etc).In every sectio/Group User must and should select minimun 2 check boxes. so If user select only one check box we need to show a pop up message as " Please select One more check box in that particular section" If User skips the message and move to next section we have to show the same message. We have to force the user to select more than one checkbox in the same section. Mainly our intention is the check boxes whatever user selected in each section/Group belongs to one Category.

I am creating a form for work where managers can report when they find a customer's personal information laying around on a desk (we work at a call center where agents answer calls for a wireless cell phone provider, so we take personal information security very seriously). Anyway, I am wondering if there is a way to have a text box autofill with that manager's windows username (since they will need to be logged into their own profile to use the form).

I need something tje user can type in data to such a parts QTY cost etc. There are no predefined parts list so the user can enter any part name/Number and there is no limit to amount of parts that can be entered.
Does anyone have any idea what might be useful. It was thinks of a listview bu i can't see that you can type into that. I cant use comboboxs because there are no predefined list and i know there is some way to generate text at runtime (i think) but i don't know how to do it and i would prefer a clearer approach.

If Not IsNumeric(textbox1.Text) Then
KeyAscii = 0
End If
I learned in MSDN and wrote those code,but it doesn't work. This code " KeyAscii = 0" it's not correct, I just want to cancel the input, for instance,if user input 1a, then "a" will be not inputted into textbox, but "1" will leave.

On my main form i need to pop up a sub form and await user input before proceeding. I am able to pop the form but not able to pause code excecution until the user input is there. Here is what i have tried:
If chk_athor_cobb_scholi.Checked = True Then
Vselect.Visible = True
While Vselect.ex2 = False
[Code].....
The problem of course is that the while loop causes a crazy infinite loop and locks the program down during excecution. How do i await the user input?
