Jan 24, 2012
I have created an application that would calculate NFL rating based on statistics pretty much everything is correct but how would i seperate the public function into multiple private one's while still performing the same actions? Example, Private Function CPA( Rather than having a single public function witch performs every step needed
Here's what i have
Dim intcomps As Double
Dim sngInts As Double
Dim sngAtt As Double Dim intcomps As Double

I did a super simple calculator with ASP.net with five buttons: add, subtract, multiply, divide, clear. There are five separate functions for each button's click event. For example: Sub addfunction(ByVal s As Object, ByVal e As EventArgs)If Not IsNumeric(input1.Text) Or Not IsNumeric(input2.Text) Then resultLabel.Text = "You entered an invalid or missing number"
[Code]...
How might I be able to combine all 5 of these functions into one? So for example, all the onclicks will refer to the same function, but will somehow be able to determine which button was clicked? I forget a lot of VB.net from a year.

As I develop code, I often want to unit test some of the building blocks of a class even if they are normally private. If my unit tests are inside the project, I can use "Friend" to accomplish this and still keep the functions private for normal use. But I would rather move my NUnit tests into their own separate project(s). How do I achieve the effe vb.net 2005?

I found this code to rotate a picture online somewhere and made some changes and it works beautifully. My only problem is how much memory it uses. Does anyone see a way for it to use less memory?
Code:
Private Sub RotatePicture(ByRef bm_in As Bitmap, ByVal angle As Integer)
' Copy the output bitmap from the source image.

I've got Visual Studio 2010 and I am looking to clean up my code technique, since I've taught myself and now I'm taking classes.
I'm trying to use a For...Next Loop so that I can fill a text box with sequential numbers. For some reason, all I can get in the text box is the last number and I feel that at this point I'm probably overthinking it...
All I want is on the button push the text box shows:
Here's what I have:
CODE:
Once I grasp this simple concept, I can move on to the actual challenge ahead of me, but I really want to know the proper way to handle this with out going all spaghetti code.

I have been using adodb as my database connection to mysql from vb.net, now I want to know if i can create a query string with 2 separate query like so:
vb
dim querystring as string
querystring="update table1 set columname = 'value' where columnname='value';update table2 set columname1 = 'value1' where columnname2='value1'"
Then I can include that to my recorset:
vb
dim rs as adodb.recordset
rs = new adodb.recordset
rs.open(querystring,con, ADODB.CursorTypeEnum.adOpenDynamic, ADODB.LockTypeEnum.adLockOptimistic)

I have produced some VBA in Access that creates a spreadsheet.I have also created an SQL query that retrieves records from an Access table.I have 48 tables (each table for a specific institution centre).I have created another bit of VBA code that creates a spreadsheet and loads the records from the query in to the spreadsheet.Each centre has a unique Sequence Number (Indent Number)At the moment though, all I can do is import one table (records for one institution) in to a spreadsheet. I want to end up with calling the function and having an output of 48 spreadsheets being saved to my desktop, each spreadsheet containing records of a different center.I have thought about putting a loop in, but not sure how I would quite go about it.
Here is my code to create the spreadsheet:
Public Sub ExcelExport(lngIndentNumber As Long, strFolder As String, strCrit As String, strReport As String)
', ctlLabel As Label,
DoCmd.SetWarnings False

I am creating a gridview and need to gather the data from various functions that return a type of IEnumerable. I've created gridviews using a dataset as a datasource, but how does one use multiple data sources(of IEnumerable) to populate one gridview? Like how do you combine all that into one dataset?

I have 2 seperate web services. They both run on the same machine.One of the functions is the same between the 2 web services. It is a huge function and i hate having to repeat code. Is there any way to share the code between the 2 services other than having one service request the function from the other service? I'm a bit hesitant doing it that way because im worried about performance. It would mean for each request into service A i'd need to create a service B instance and call it.

I am just starting out with a practice VB project which involves selling donuts and coffee. I have written out the code which the program works but the code is very messy. This program contains functions and radio buttons to calculate a subtotal, tax, and total due. There are four variety of donuts in Group Box 1 listed as: Glazed at .65 each, Sugar at .65 each, Chocolate at .85 each, and Filled at $1.00.
The coffee choices in Group Box 2 are listed as: None at 0.00, Regular at $1.85, and Capuchino at $2.50 each.I want the cashier to be able to select a radio button to choose between the donut choice in group box 1 and then choose one coffee choice in group box 2. A textbox calculates the subtotal, a textbox calculates a tax of 3%, and a textbox calculates the total due adding the subtotal and tax.
Everything works fine but Ias I said before it is quite messy which I keep making it worst.I need to write one function to calculate the donut, one function to calculate the coffee, and one function to calculate the sales tax. Then I need a sub procedure to clear the subtotal, sales tax, and total due amounts when a radio button is clicked.I have been working on this for the past month ,code I have so far:
Class frmMain
Private Sub btnExit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnExit.Click
Me.Close()[code].....

I am creating an IDE for a game script with similar functionality as the Visual Studio IDE (at least, some of it). The game script consist of code that looks visually a bit like C code. It uses braces to define the start and end of a 'class' and uses nested braces to define the start and end of an 'event' in a class.
What I want finally is to have two Comboboxes above the text editor, one that lists each Class and the other listing each Event. The comboboxes should also show the Class and Event that the caret is currently in, just like in Visual Studio.I have attached an example of such a script (you can open it with Notepad).However, here is a short example where you can also see how I "defined" classes and events:
class1
{
event1
{
[code]....
As you can see, the classes are the 'names' of each block of code, defined by matching braces { }. The events are the names of each nested block of code, also defined by matching braces { } but inside a class. There is only one level of nesting.As you can also see, the layout can follow the standard C-style layout, or a slightly different layout (using the opening brace on the same line as the class/event name), or even a completely chaotic mess. As long as the braces match correctly, the code is valid.So in short, the large blocks are classes, while the nested blocks are events.
What I want to do, is parse an entire script, and store all the Classes (and eventually, also all the Events, but let's forget about them for now). I want to store the Class name, start position (defined as the start index of the name), end position (defined as the index of the closing brace) and the full text (defined as the text between start and end position, so including the name).
vb.net
Public Class clsClass
Private _Name As String
[code]....
The code works basically by finding every first opening brace (the opening brace of each CLASS, not event), and then loops through the class (using a brace counter to keep track of the nested braces) until it found the last closing brace. It then stores the name, start, end and fulltext in a new clsClass and adds it to the list to return.

I'm trying to validate a form to be filled out by the users, and when the required section isn't filled, I increment an
ErrorCount += 1
variable to show that error(s) have occurred inside the program, I then also set an
ErrorArray()
to whatever the corresponding field number is, now I have 0-12 (13 fields). What I have also done is titled the labels that are associated with all of these fields to correspond with the ErrorArray() value that might be set, such as.
PatLabel0
PatLabel1 etc.
What I am trying to do is loop through the array contents, depending on which ErrorArray() values have been set, to go and set the corresponding fontcolor property of that label to red, to show that these now need to be filled out. This is what I have, but Visual Studio doesn't allow me to use the iteration through the loop as a reference to changing properties. Can anyone point me in the right direction to trying to figure this out, or at least tell me what else I could do. Just seems doing 20 if....then....else.... statements with 2 - 3 lines in each of them is redundant when 1 function line could do the same job. This is what I have.
for i = 0 to UBound(ErrorArray(12))
if(ErrorArray(i) = "*")then
PatLabel(i).forecolor = color.red
[code]....
that is basically all im looking for initially, but I can't do it.

I have an Active Directory browser written in vb.net 2008 that allows an end user to visually browse AD. Currently it displays the full DN for each child and what I want is to display just the name of the OU. Something tells me I would use the Tag() function but after playing with it, I just couldn't figure it out. All I removed was our internal domain name.
Would someone like to review what I have now and offer some ideas on what I would change to alter how the tree is viewed while retaining funuctionality?
