Adding Fields To The CreateUserWizard?
Jun 15, 2005I'm trying to add a textbox to the initial step of the CreatUserWizard.Let's say it is tbMyTextbox.Now when I add an event on created user, I want to get the value in the field.I thought I could use dim mc as textboxmc = ctype(CreateUserWizard1.Findcontrol("tbMyTextbox"),textbox)mc.text should be the text of the field.But it can't find the control... so I trieddim mystep as CreatuserWizardstepmystep = createuserwizard1.activestepmc = ctype(mystep.findcontrol("tbMyTextbox"),textbox)But it also fails.The example just uses tbMyTextbox.text which just throws a compiler error.

Feb 23, 2011I am attempting to customise the CreateUserWizard by following it in my book, but when I come to reference them in code behind I get an error saying 'FieldName is not declared' for each field i'm adding, they are present in the page with the correct ID's, am I doing something wrong?
I am only trying to add a firstName and lastName field to the bottom of the CreateUserWizard and remove the need to a security question.

Ms SQL: Adding Fields In Sql In Each Loop Automatically
May 8, 2012i have an SQL statement which i need to code in vb:
create
table r2 (salesno
bigint, prodno1
[Code]....
Note that in this "2nd loop"
- the table name is now r3 from r2 in the first SQL statement
- there are now prodno1, prodno2 and prodno3 instead of just prodno1 and prodno2
- in the WHERE clause, the p.prodNo becomes p.prodNo2
and so on and so forth.. so for the 3rd loop
- there's going to be r4
- there's going to be prodno4
- in the WHERE clause i will use p.prodNo3
what should i do? is there an array or something that i can use here?

Time Display - Adding Hours To Convert UTC Time

I have tried about 50 different things but cannot get it to remove the date when the converted time passes midnight. [Code] The string was not recognized as a valid DateTime.

VS 2010 Adding Unique Tag After Adding Component
May 4, 2012I'm adding labels at runtime to my form with a tag. Let's say I have 3 labels with the tags, "1", "2" and "3". I'm adding the tags by counting the labels + 1. When I remove a label with tag "2" from the form there are only 2 left. When I add a new label it will add a new tag "3", but that one already exist. So my "solution" isn't a very good one Although tag "2" is free, I want to give it "4". Any thoughts on how to code this properly?

View 6 RepliesAdding Time To Date?
May 28, 2009I have an SQL Server database with a table in it that has a column labeled DATE (datatype =date).The table also has a column labeled TIME (datatype Integer) that contains hours and minutes.I would like to be able to display the time in a datetimepicker also.
Would it make sense (remember I�m new to VB) to have the time as part of the date column?Doesn�t the date/datetime data type include time(7/24/1996 12:00:00 AM)?If so what is the best way to add the TIME column to the DATE column.I know I can go back to our other system (IBM iSeries) and combined the columns and transfer the data over again but that is chore (the transferring) and I want to learn how to do these kind of things without falling back on my IBM skills.It seems I should be able to add time to the DATE column of the table. None of the DATE data transferred over to this table had time with it.

Refactoring A Module Into A Class: Changing Shared Fields To Instance Fields
Nov 14, 2011I'm currently refactoring an old Visual Basic DLL (VB.Net), which stores all of its data in one module called Globaldefinitions as public fields. There are about 200 fields, referenced thousands of times all around the code:
Public Module Globaldefinitons
Public a As Short
...
Public zz10 As Double
[Code]...
I need to change the module into a class with non-shared fields. This means, each and every of these thousands of references needs to reference the instance of that class:
globalDefinitionsInstance.a = 5
How do I go about this efficiently?
Regular expressions operating on the source fall flat. Refactoring tools like Re-Sharper or CodeRush don't seem to offer this functionality. Visual Studio 2010 cannot do it automatically either.

Can The Initialization Order Of Class Fields In .NET Be Influenced By References To Other Fields
Jun 19, 2011Class Foo
ReadOnly name As String
Public Sub New(name As String, dependentUpon As Foo)
Me.name = name
[code]....
The output of New Bar() is:
Dependent created. Dependent upon nothing.
Independent created. Dependent upon nothing.
It seems fields are initialized in the same order as they appear in the source code, which (a) leads to an unexpected result, and (b) seems a little puzzling, given that one is normally not permitted to read from uninitialized variables in .NET, yet that seems to be working fine above.I would've expected VB.NET to be smart enough to initialize referenced fields first, and only then those that reference it; i.e. I'd have liked to see this output instead:
Independent created. Dependent upon nothing.
Dependent created. Dependent upon Independent.
how to get VB.NET to behave like that instead, without simply having to swap the declaration order of dependent and independent inside class Bar?
Create Word Form Fields With Memo Fields From Access?

View 2 RepliesVS 2010 Calculated Fields In A Datagrid?
Feb 17, 2011My program is databound to an access 2007 database. I have a datagridview showing rows as part of my screen and the other part of my screen is texboxes bound to a different table.What I currently have:
1. Date in textbox from one table
2. Age in Datagridview column from another table
I need help with having a calculated date column in the datagridview that will be the textbox date + age (in days) in the datagrid column. I would also need this column to store in my database like any other field also. So if I typed in 2/17/11 into the textbox, and I typed in 2 in the age field, the calculated field would display and store 2/19/2011 in my datagrid and database. My dataset designer won't let me add a date to a string so I'm completely lost. A query calculates it easy in access but when I load the access query in my dataset it doesn't calculate anymore.

Apr 5, 2011I have been using VB a fair bit in the past developing a Access Database, recently I wanted to give my front end interface a bit more power so I have started learning VS 2010.
Anyways, I am still using Access for my databases and i am having a bit of trouble working with the data in VS 2010, what i would like is the following:
A way to form a string or integer from a SQL query (from a single field or multiple on that row) assuming the query will always return one row.
Then a way to write string or integer variables back in to db fields.
example:

Dim cmd As New OleDb.OleDbCommand With {.Connection = cn, .CommandText = "select * from tblItemregister where ItemID = 1"}
