For some reason I can not get some fields to calculate correctly. It seems anything I enter over 24 in the Pay Rate field it throws it spits out the exact numbers I am trying to multiply. The FWT (0.2), FICA(0.08),and State fields (0.25) respectively.

I'm trying to get an If statement to check is the date picked from a datetimepicker is at least 3 days prior to the current date, I can get it to calculate the difference however if I chose a date that 4 days prior to the current date (i.e the result being -4), the else statement doesnt fire.is this something to do with the result being a negative value? I did try to assign the DateDiff result to a variable defined as a short and then used this variable in the If statement, but still get the same issue. Option Strict isn't showing any issues.

I am making this program for a school assignment but it has errors when calculating
Private Sub frmReceipt_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'When this form is loaded, assign the date to the date label & start the timer
lblDate.Text = Date.Now

So if counter finishes, execute the following code
If counter > 4 And km >= 1 And kmcashset = 0 Then 'If there is still kms to calculate 'And kmcashset = 0
kmcashholder = kmcash
km = km / 5
[CODE]...
And if I add counter = 0 and km = 0 at the end of that "If counter > 4 And km >= 1 And kmcashset = 0" Then it doesn't calculate anything correctly. I supply it with 9 for Distance and it returns 4 for excessdistance which is correct but returns 7 for excessdistancecharge when it should be 4! When I supply 23 for Distance it returns 18 for excessdistance and 11 for excess distance charge which is correct. (???)
Excessweightcharge calculates correctly.
I think it may be the way I'm implementing it, through the use of AND or maybe it's because it's in timer tick?
-Minimum charge of $5 which covers 10 kgs for the first 5 kms only
-Each kg over 10 kgs incurs a charge of $0.50
-Distances over 5 kms incur an additional charge of $1 per km up to 10 kms
-For deliveries over 10 kms, the extra distance should be rounded up to the nearest 5 kms and charged at $2 for each extra 5 km block.
EXAMPLE 1:
Packet weighing 9kms travelling 9 kms
Standard charge for first 5 kms ($5.00)
Weight less than 10 kgs so no extra weight charge
Extra distance charge 9 - 5 kms = 4kms x $1 = ($4)
Total delivery charge = $5 plus $4 = $9
[But my program returns 7 for excess distance charge]
EXAMPLE 2:
Packet weighing 33kgs travelling 23 kms
Standard charge for the first 5 kms ($5)
Excess weight 33 - 10 kgs = 23kgs x $0.50 ($11.50)
Extra distance (23 - 5kms = 18kms):
18kms ( 5 to 10 kms at $1/km) = ($5)
13kms (18-5)/5 = 3 (rounded up) x $2.00 = ($6)
$5 + $6 = $11
Total delivery charge = $5 plus $11.50 plus $11 = $27.50

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]...

I'm having a problem over here; I'm developing a DirectX 9 application, and for some reason, I can't figure the way to close the application completely. This has never happened to me, to be honest.

I have also tried End, but it throws a run-time error I can't seem to figure out.

This form works in VB .NET
sendMsg = "<CStatus timestamp=""0"" " & _

But I can't get it work in C#
sendMsg = "<CStatus timestamp="0"
type="login"
cid="" + cID + ""
key="" + loginKey + "" />";
It does not give the same effect. I want this as an output:

Is there any stringXml command in C# or another way to use double quotes in string?

View 4 RepliesI 'm having no trouble coding, I'm back to my initial printing problems. The program printed Avery labels in a variety of sizes. I created the label templates on 8.5 x 11 forms and then printed the forms. This cannot be done in VB 2008 for a variety of reasons:
1) The form size cannot be larger than the screen size I got around this by creating a new form class that matched my dimensions.
2) printform only does screen shots. This was a major barrier. First of all I can't get printform to print my custom form because it's not a member of system.window.forms.form, it's a class in system.window.forms.usercontrol. However, even if it was in the correct class, it wouldn't work correctly because printform in VB.net, does a screen capture of the form and then reduces the image on the printout.
So that is my dilema. I do not know how to use the reporting tool, but I can see that it must be binded to a database. Although my application does use a database, I want to be able to massage the data before printing it. And the application does more than just print labels. There are also custom reports that need to be printed.
