Currently working in VB 2008 Pro. I have a web site connected to an SQLExpress database. I have a databound form that needs to calculate some basic math. I have a button Click event in code behind file, when I try to enter code intelisence not active and fields not available. I tried to work the math in the select query SqlDataSource, but form would not update only insert.

For instance, im wanting to add a field for employee id but can I also get this field to show up in active directory users and computers to see if its working correctly?

View 5 Repliesi am making my final year project in vb.net for data entry i want to make the project more user friendly i use code to change the control focus by pressing 'Enter'(ASCII 13).. and clear the content of current control by pressing 'Esc'(ASCII 27)... in my project one form contains at-least 300 of controls say(t1,t2,t3,t4...)
so in the keypress event of t1 i have writen
if asc(e.keychar)=13 then
t2.focus
elseif asc(e.keychar)=27 then
t1.text=nothing
end if
the code works fine but produce an alert beep when i press ENTER to change the active control...
in VB.NET DGVedit mode, after press ENTER to move the active cell into the desired cell, notdirectly move to the next line, how is it?

View 3 RepliesI just signed up today, and i apologize if i posted in wrong section.It's my first time using VB or VSTA, I a have no programming knowledge.I'm creating an infopath timesheet, and im trying to have it set up to grab the persons name and manager from AD.
I read from a MS site on how to do it, but it was not clear enough for a beginner. Site: Adding User Information from Active Directory Domain Services to InfoPath 2007 Forms Now, I've taken a screenshot of what i did, but i really need help as i have to have this set up by this week.

How do i set the active cell by code?
Lets say after cell(0,0) has been edited. On the cell Leave event it must set the active cell to be cell(0,4)
Is it possible to skip a code block when a synclock is active?
For instance:
A object of class Bicycle is used by thread 1 and has a synclock on it.
Then thread 2 comes along and needs to know if the lights of the bike are working. But if there is a synclock active then thread 2 just forgets about checking the lights and goes to make a delicious chocolate pie.
I have this Text: Hello <<FirstName>> <<LastName>> in which the <> and <> are merge fields in a document, and I have a list of customers in an array which I want to allocate them to these fields. How do I do that?
View 2 RepliesJust suppose that I define a structure, and an array such as
Structure Person
Dim First_Name as String
Dim Last_Name as String

Can I fill in my list of people using a single line of code for each record? Something like this, it doesn't work, but this shows the sort of thing I mean.
My_List(0) = {'John', 'Smith', 24, '555-1234'}
My_List(1) = {'George', 'Jones', 31, '555-8123'}
My_List(2) = {'Tom', 'Green', 40, '555-3434'}
It's easy enough to fill it in line by line. I could do that without problem. But I want to be able to look at the code and see the contents of each line. Doing it as above would make it easier to read.I could make it a multidimensional array of strings, rather than a structure.If it makes any difference I'm using Visual Basic 2005 Express Edition.
I am converting a VB 6 app to VB.Net. In the vb 6 version I have a table that contains roughly 80 fields. Over that table the users currently have a single form which gives 12 diferent views. Each view is placed on a different tab, which, although giving a distinct set of fields per tab, also leads to a ton of duplicated code. Changing the underlying table is not an option.
What I would like to do is to use a single datasource (containing all 80 fields), a single datagridview on the form, and have a combobox act as the filter choice for the differing views. Does my solution seem like the right way to handle this? If so, I'm not sure I know which controls would best be used.
I am using the given code to copy my database files...it works like a charm in debug mode but as soon as I create a setup, it stops working. The error is

I tried checking the code line by line and found that the code does not enter the IF block.I have no idea why.

I am having issues understanding why it is that a text box that has been bound to a dataset correctly updates that dataset when the text in the box is manually changed i.e. by changing it using the keyboard but the dataset does not recognise the change when I change it in code.Am I missing something obvious? The text is changed in code when the user clicks on a command button that copies the text from another textbox on the form to this textbox.
[Code]...
As i mentioned, manually it works fine but when I use the comman button to change the text it does not recognise that any changes have occured.

View 9 Repliesi am trying to make it so that when you are typing a url into the url box on my web browser, you can click enter to search like on comercial browsers instead of having to click the actual search button, im trying to do the same with the web search(google, bing, yahoo!). it worked before, but i've added a tab system to the browser and now it's not letting me click enter to search.
my code:
Private Sub urlgo_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles urlgo.KeyDown
If e.KeyData = Keys.Return Then
CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).Navigate(urlsearch.Text)

I have an SQL statement which i need to code in vb:
CODE:
Notice the fields prodno1 and prodno2 in the table structure.. this is part of a number of sql statements i need to run and put inside a loop. my problem is i want to automatically use this same code such that on the next loop, this sql statement is going to be:
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
a simple question. Given the following code:
Public Class MyClass
Private WithEvents pPerClass As PersistableClass
Public Overridable Property PerClass() As PersistableClass
Get
Return pPerClass
[Code]...
the first being a duplication of the second key, strangely obtained from a private field.
If you remove the WithEvents keyword, the pPerClass_PersistableClassID key is not created.
I am new to EF but it seems to me a strange behaviour.

I'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.
Class 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?
I'm trying to create a table in Word using data from a table in Access. There are four fields in the access table that I need. 3 fields are text which I can populate the Word without any issues. However the fourth field is a memo with >255 characters.I'm struggling to come up with the proper code to allow me to populate the Word field with the memo data that has more than 255 characters. The code I have so far is listed below. But when it hits the memo field, it crashes on the line I marked with **. I know it's not text, but I've tried many different field types, but nothing has worked so far.[code]...
