Run Time Control Creation - Add X-number Of Text Boxes At Run Time
Jun 9, 2011
Just getting started in VB.NET. I would like to add X-number of text boxes at run time. And then be able to address them by their index or some sequential numerical value (like an array)
This is what I have so far:
CODE:
When I turn this into a loop to create multiple toolboxes, how do I assign a name to the controls, or will all of them be named "MyTextBox" ? I'll increment their position so thats no problem.

I am using the log in feature that comes with vb.net
Public Class LoginForm1
' TODO: Insert code to perform custom authentication using the provided username and password
' (See http:go.microsoft.com/fwlink/?LinkId=35339).
[code].....
I need to know if it is possible to set (as I am going to put in after only if it is possible) a time delay, e.g. If a user gets the username and or password wrong 3 times it will disable for lets say 10 seconds, then after another two attempts for a minuet.

What i am looking to do is to be able to save/load all the values filled into a form. For example The user has entered the
name: "Tim"
address: "123 Fake Street"
phone: ""
And then saves. When the come back and load this i want to be able to load it back exactly like that so the can continue with what they are doing. And if there are to open a different person they can continue with that one where they stopped. I want to be able to save them all at once and load them at once.

Using the datetime function to determine lapse time. (Subtracting one from another.) Then placing the answer into two text boxes one with the date and one with the time, later to be placed in a database as two seperate fields. Was thinking I could convert the date/time to a string if necessary then use simple stringmanipulation.... however fear it won't be good programming and will effect resources and end program speed.

In VB if you prompt the user for a number between 1-20, then a word, how do you get a text box to show the word the same number of time as the number selected using loops?... Ex: please select a number: 4 / select a word: cat....the text box should display ::: catcatcatcat ........
I am doing this for a class and my brain has locked up. Prob. just over thinking it though. Thanks in advance for any help!

i need to create like this only...
i.e in SALES form, CODE, CATEGORY, BRAND, S.P, DATE, QUANTITY, TOTAL etc., are available... when i click a BUTTON say NEXT, the controls specified(CODE, CATEGORY, BRAND, S.P, DATE, QUANTITY, TOTAL) has to be created automatically, in same size,and in same COLUMN (in form)(i.e CODE is a COMBO BOX, WHEN I PRESS NEXT another COMBO BOX has to be created in same COLUMN), whenever i press the NEXT...
and also, when i press SAVE BUTTON, ALL THE DETAILS HAVE TO BE STORED IN DATABASE...

I have a ERP system which create a PDF file and write it to the disk when the invoice is beeing created. On the other side a have an .NET app, which every 10 minutes read data in that folder and automatically send an e-mail to my customer with the invoice attached.The problem is that sometimes, when .NET app try to read a file which currently is beeing created -> The file is damaged. How to avoid such a situation? Is there a way to e.g. read only file creation time, and if it's "younger" than 5 seconds order app to wait a while?

I have a form with the DateTimePicker control on it. When I select a date it gives a value like "date time" (Eg.: 5/12/2010 12:20:35 PM). But here the time returned is current time. What I need is for the date chosen from the picker automatically set the time to 00:00:00 instead of the time when the date was picked.

I have an ASP.NET application with a SQL Server back end. I am storing all my dates in UTC format and doing the appropriate conversions to the local time zone of the browser viewing it. One of the pages asks for a start date and end date (no times).
I am taking the start date and setting the time to 00:00:00 hours (midnight) and I'm taking the End time and adding a time of 23:59:59, so that the date range covers the whole day. Now what I'm trying to do is do a SQL query to do a search for records in this date range. The problem is, the data in SQL is in UTC time and the user is typing their dates and times in their local date and times. My quickest solution was to convert the date and time to UTC, then search the records. However, by doing this, I am to believe ASP.NET converts the given time and date to UTC based on the server time zone. How can I convert a date and time to UTC time based on the time zone of the user?

What I to do is really simple. I want to add a group of text boxes in my VB net application. note that the number of text box only can be known at run time.
I want to give default value to this group of text boxes. At run time, users can input text and change the text for each item.
How can I do this? Is there a control to do this?
What I can remember is ComboBox control. However, I only can display the item text and do not know how to change the text for each item.

I have to make a lot of retangular boxes to make my program neat but i'm having a problem of adding boxes. I tried using the draw event in the tab page but everytime i scroll it will draw the lines again and messes up everything. Also when making a line greater that the tab page, autoscroll won't work.
Is there a way to make lines or boxes in design time?

ok.. just as it sounds.. I'm kinda making a document portal app for work.. has 4 list boxes going to 4 different drive locations.. for cosmetic reasons I want only the last box you clicked in to show a selected item.. so if you selected box 1 item and it was hilighted and then you went to box 2 and selected something I wanted box 1 to then dissapear.
I have some code written to handle this.. but its not working so well.. since I use the SelectedIndexChanged trigger to fire off another piece of code to unselect all the other windows.. those listboxes fire their triggers also because I have to call lstWord. SelectedIndex = -1 to make it not have something selected anymore.. and when you do that.. it calls its SelectedIndexChanged and ends up deselecting everything.. so wasnt sure if anyone had done something like this before.. seems like something that would have been done before.. but as you can imagine searching the web for "multi list box select only one at a time" or something similar..gives you some strange results..

I heard that you have to add some code to a random number generator
results(1) = Int((5 - 1 + 1) * Rnd() + 1)
so that if it is used again and again it keeps generating new numbers as apposed to what this piece of code does by itself which is creates the same number every time.what is the code?
