VS 2010 Payment Form - How To Add Currency Fields
Jun 12, 2012
I am starting to design a payment form that the user enters rent information and any payments/deductions. Should my fields in my table be set to decimal or double? Currently they are ALL set to Currency. I'm trying to add the fields but it don't seem to work. I know this one wont work: You cannot do math operation over string (Text property of textBox is just a string).
HTML
txtAmtOwedThisMonth.Text = txtTenantAmt.Text + txtHousingProgramAmt.Text + txtDeposit.Text + txtPetDeposit.Text
Tried this as well
txtAmtOwedThisMonth.Text = Double.Parse(txtTenantAmt.Text) + Double.Parse(txtHousingProgramAmt.Text) + Double.Parse(txtDeposit.Text) + Double.Parse(txtPetDeposit.Text)

experience on how to create an engine using C# (VB.NET is okay too) that is generic enough to handle most cases of MS Word text fields I need to fill with data I'm getting from a database? In short, I'm about to embark on this little Office automation excursion and I'm hoping a little bit of feedback here.

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]...

I have a table with many fields when I drag the details from the data sources tab to the form some fields do not show, and they go beyond what I can grab with a "blind group select" (I marquee beyond the bottom of the form and catch fields that I cannotsee). What can I do to place all fields on my form.

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.

I have a problem trying to copy 3 fields on a form to a database. The reason I cannot seem to do it is that the last field asks how many copies you want to save in a combo box. So lets say the user selects 3 I need to be able to copy three sets of the same data to the database.

I am developing an application in which I would like to let the users design some forms and decide the fields that are in the form.An example is better than a poor explanation, so let me put the example of Microsoft CRM in which you as end user can define a form, the fields in that form, or customize existing forms by adding or removing fields.

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?

My intent is to have the code - on a button.click event - check the Username and Password fields and return an error depending on which is wrong. Or if both are wrong, return a different error message. I've set the username as parts and the password as parts (still learning how to use external authentication). [Code]

My 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.

I 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 cn As New OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|ItemRegisterDB.mdb")
Dim cmd As New OleDb.OleDbCommand With {.Connection = cn, .CommandText = "select * from tblItemregister where ItemID = 1"}
[Code]....
Example = ??? 'What would i need here to copy fields from that row to string?

I used to run into problems with this in VB6, too...
If Not ds_Students.Tables(0).Rows(0).Item("ClassDay2").IsNullOrEmpty Then
txtClassDay2.Text = ds_Students.Tables(0).Rows(0).Item("ClassDay2")
End If
This produces "Public member 'IsNullOrEmpty' on type 'DBNull' not found."
And is there a different test for fields of different data types?

I need to build a rather simple form for collection some information from our membership. It has 4 Text boxes and one Submit button. The contents of the text boxes need to be emailed to a fixed Address and a fixed Subject. Before I got to fancy I tested the form to see if the email portion worked which I did get the email but not all the data. I am trying to stick with VB as I had experience with it years ago.
My problem seems to be in building the string for the body of the message. Trying to use StringBuilder but my syntax is messed up somewhere. The Fields that I have are: Name, Phone, Email Address: and Comments. They are named in the form as txtName, txtPhone, txtEmail and txtComments. [Code]

I am an experienced programmer but am new to VB. To start, I am trying to create a simple database program. (My ultimate goal is writing a comprehensive database program in 6-8 months)I have created the database and bound the fields to a form.
But what I want to be able to do is add a field to the database and then also bind that new field to a textbox on the form.The new field appears on the list in the Server Explorer window (on my left) but not in the data sources window (on my right.) The data sources windows has a "refresh" option but that does not help.When I manually add a textbox and try going to DataBindings in the property window the new database field is not listed.
