VS 2008 : User Control For Date Entry?
Dec 29, 2011
Im trying to build a user control to enter date as dd/mm/yyyy. I want to create a text box control so the user can enter the date without making a mistake.ex:-Lets assume that the user is trying to enter 31/03/2010 so when the user types 3 first the next number allowed should only be 1 or 0 because there cant be any date more than 31.and if the user enters 31/ then he should only be allowed to enter a month which has 31 days. Im trying to implement this codes in keypress method.So it checks the errors at runtime and prevents the user from typing a wrong value.So far i have got to something like this but Im stuck.Please help
Dim IndexOfCursor As Integer
IndexOfCursor = textbox1.SelectionStart
chr = e.KeyChar
[code]....

I don't think this can be that hard but I just can't get my head on it. I have a connection to an Access DB, put three text boxes representing three columns in the DB. Using the DataNavigator everything works. But what I want is to be able to enter text in say textbox1 and have textbox2 and 3 update, like when using the navigator.
Add: I want this to function like when you enter a record number in the Navigator and hit Enter, bam, goes to that record and all the text boxes update. I want to enter a number in textbox1...

I need to write a program in VB 2008 express that takes an user entry from a textbox and strips out all the spaces, changes it to either all upper case or all lower case then checks to see if it is a palindrome. I must also include a loop structure and a decision structure. I have seen bits and pieces of code but I do not really know how to put them together. Basically I need it from the button click to the end. ?

I have a oracle database. I use the OracleDataAdapter(Oracle.DataAccess.dll) for select, update, insert, delete operations. I don't set any (table) locks on my own(I only start a transaction). I have a oracle table named "test" with the entry "test1".
Now my question: Can Person A read the entry "test1" while Person B is updating/deleting the entry at the exact same time? What happens in the worst case? An old match/empty match or can it cause any kind of exception/error(e.g. "TableLocked-Exception")?

My project requires users to be 18+. I have supplied a textbox for birthdate entry, but I don't know if that's the best way. Also, I don't know how to format it so that it only accepts date entry.
Next is the calculation part... yikes.
today - bithday = age
Code:
Private Sub Birthday_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Birthday.TextChanged
End Sub

I have DateTimePicker where user can choose a date and make entry. I then record this entry into the database. My application date shows 08-02-2012 (i.e., 08 february 2012 in DTPicker value), when I select this and insert it to my database, the MS Access takes this as August, 2 2012, and records it as the same.
I could fix this by using this code:
Dim mydate As DateTime
mydate = Me.dtpicker10.Value.ToShortDateString
Dim output1 As String = Format(mydate, "MM-dd-yyy")
and pass sql insert query using
insert into table (mydate) VALUES (#" & output1 & "#)
Instead of getting the value directly from the dtpicker. This fix the issues, but when I tried to get the date out of the database to filter it between entry made in certain date, I sometimes have problem. How do I generalize this for all type of client computers where the date and time settings can be any form. What will be the best and more flawless ways of approach to target all types of clients? Am I on the right track?

Using VB.Net and Sql Server. I want to check the user Entry Value. The User is entering the code in the textbox, before saving to the table, I want to check whether code is already exist in the table or not.
Tried Code
cmd = New SqlCommand("Select code from table where code = '" & textbox1.Text & "' ", Con)
dr = cmd.ExecuteReader()
While dr.Read()
End While
If value is exist, then message to the user "Already Exist" other wise save to the table.

I am trying to learn VB.NET and I've written a user entry screen to store and retrieve information. I keep getting this error. I understand that I have to either change the ref value from the calling code, but my problem is where is the calling code? Here is the error I'm getting (the program is underscoring udtTrans in the FileGet line in this segment).
Private Sub viewRecords()
'open the file and read fields of the first record into the textboxes
Try
FileOpen(1, strFilename, OpenMode.Random, OpenAccess.ReadWrite, OpenShare.Shared, Len(udtTrans))
FileGet(1, udtTrans, intCurrentRecord) 'gets first record

I have a form with textboxes for entering data. One of the textboxes is for entering a value that is always one character. How can I make the cursor automatically jump to the next control when a character has been entered? I'm thinking the key press and release event and then set focus but is there a better way?

If DateTimePicker1.Value.Year <= DateTimePicker2.Value.Year Then 'dtp2 = expiry date
If DateTimePicker1.Value.Month <= DateTimePicker2.Value.Month Then
MsgBox("Expiry Date Correct!")
Else
MsgBox("Expiry Date incorrect!")
End If
End If
How would I get it to check the date? Datetimepicker1 is the current date, while Datetimepicker2 is the expiry date.

I've seemed to found some interesting behavior with the stock MonthCalendar control. I've set the MinDate property to 1/1/1990 but when I try to actually select a date anywhere previous to 1/1/2000 it jumps to 12/31/2999 why is that?
I've tries manually setting it to 4/8/1998 and it jumps to 4/8/2998 which isn't what I would expect a calendar control to do. Is there a reason it keeps it within the 21st century?

I have a form that collects user parameters to print a report. There are two DateTimePickers to let the user select a date range for the report. The selection of a date range is optional so I set the From picker to a date before any data could be present. If the user wants to select a date range, the from field is set to a very old date so it takes a long time to get to any current dates. Whe I'd like to do is when the user drops down the picker, reset the date to today and let the user scroll from there.I tried the dropdown even in the picker, but the new date doesn't get set until the user has already selected a date. Any suggestions on how to get this type of UI behavior? Also any better suggestions to streamline the process?The main objective it to collect from and to dates from the user is they want to select them and collect wide ranging dates if the user doesn't enter any.

I have an aspx page that has two different user controls. I want to find user control A and be able to set properties, etc., from user control B.
I was thinking I could do something like this:
Dim CMFilters As Control = Me.Parent.FindControl("CMFilters")
...but that doesnt work to be able to set properties and call methods. I somehow need to get the user control and and declare it as that user control type.

I need to have 4 text boxes and three command buttons. One button should be used for exiting the program, one button should be used for clearing all of the text boxes, and the last button should be used for any calculations/conversions. You should also have a radio button group for the user to choose entry temperature type.
One text box should be used for the entry of an initial temperature. The radio button group will then allow the user to select the entry temperature. When the button is clicked for conversion, the other three text boxes will populate with answers to the conversion. and if I enter 37 degrees Fahrenheit, the Fahrenheit text box should read 37 after the conversion.)

I'm presently creating an application which uses Access2007 as the database. No problem there. But Since most use Excel for data-entry, i've created two tables in access linked to excel source file. Any change in excel will reflect in Access database and subsequently in my Application . Until now my application only reads the database and displays records in DataGridView. These records, i then export to excel along with other formatting for direct printing as a report as I have no idea how to make report. Now i want to add data-entry capability to my app using password-protection user-access. So i can directly add new record to source file. Also need to know if There's any way of eliminating Access from the picture entirely....

I use VB in VS2010..My form has a textbox..I can control the keyboard entry by using the SuppressKeyPress method..However this does not work for the Menu key - I think it's the menu key - the one that looks like a combo with an arrow.This produces a large drop-down menu which I don't want.On checking various forums it appears that the following code should work..[code]

writing user info such as user, computer name, date, and time to an acces database using a button click event. Then use a query to check if the user has accepted the aggreement. If the user has accepted the aggreement then call a vb.exe that display the aggrement. I have a login script that runs the vb.exe and uses a button click that records the user info to a csv file, but if the user has already agreed to the policies I do not want it run again.
