Array / Loop Does Not Display Properly
Mar 19, 2012
This program is to display the monthly payment and amortization table for three mortgage loans with the same loan amount, but three different interest rates and terms.The ArrayIndex is not looping properly.The first loan displays correctly, but the other two only display the monthly payment and not the amortization table.[code]I originally had the For...Next loop in the DisplayAmortizationTable() sub with the Do Until loop nested in it. My instructor had me move the loop to the Main() sub, but it did not help.

For some reason, it seems that the outer block doesn't seem to update recursively, as I expected it to. I want the loops to add all directories within "C:UsersDrise"to the array internaldirs(). Any advice on the correct way to do this, as it seems I'm doing it improperly?
Static internaldirs() As String
internaldirs.add("C:UsersDrise")
For Each internaldir As String In internaldirs

I started this tutorial on sub procedures and am having trouble trying to get this program to execute properly. The problem lies with the total. I am trying to figure out the math part of it. When I hit F5 I can see this
Item Quantity Price.
Pizza Slices
Fries
Soft Drinks
Total
But I can't get them to add up and display the quantity and price. I tried the ByVal and ByRef code but am not sure if I did it right
Here is the code that I have so far:
Public Class Form1
Private Sub btnCompute_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCompute.Click
Dim pizza, fries, drinks, total As Double

I am looking for a code snippet which opens a image, creates a clone of this bitmap in memory disposes this opened image so that all handles are closed.
Usually we can open a bitmap using this[code...]
the following code however keeps the Image File locked until the application is running, any suggestions how to dispose it properly. (So that no handle is left open )
Things i already tried: use dispose method of bitmap <= doesnt work (need to write implementation)
Using Block also doesnt work.

I'm fairly new to VB 2010 but very familiar with programming in other languages. I'm trying to make a quick application but I'm at a stand still. I know it's something simple but I've searched around and I may have found the answer but because I don't understand the problem I'll never know. So here goes.
I'm not at my programming station at the moment so I'm going to be very general with my example. Here's what I want to do[code]...

using a for loop i want to be able to pause it, display string in text box for 60 secondsthen move to the next loop,change content of the string and display it again for 60 econds.this should go on till end of count.i am currently using a timer in do while loop to pause, but instead of displaying the string contents in each loop,it adds up all contents in all the loops and displays them at the end of count,not what i want. i tried using 'sleep'funtion but its behaving the same.below is the code:
For i = 1 To count Step 3
'empty string
disall = ""

I'm using visual studios 2008, VB9 and I am trying to write an app that basically performs calculations on a set of data input by a user. During the calculations, I want to display the data at each step, and have it retained in the display area on the GUI (not overwritten by the next data being displayed).
For example:
UserInput = 1
Do
UserInput += 1
[Code]....
I tried this, and other loop structures and can't seem to get things right. The actual app is a bit more sophisticated, but the example serves well for logical purposes.

I am designing a prisoner system
On the design i have different text boxes that display the prisoner name, birth date, number etc.
I then set all of the the different prisoners up in an array.
I want to know how to loop though this array so that when i start the program up it will start at the beginning of the array with the first prisoners details and then when i click "Next" the next prisoners details will be displayed in all of the boxes.

I have a procedure that loops through the directories and subdirectories on a file server and sets the permissions. Procedure is called on a button click on a form.
I need to display on the form which directory is being processed. Similar to if we use the Debug.writeline which writes to the output in Visual Studio. I tried using a ListBox but it only displays the last one and only displays the last one once processing is done. I want to be able to display each directory name as it is being processed.[code]...

I'm writing a loop to go through the first array of a 2D loop, and I currently have it like this:
For Each Dir_path In MasterIndex(, 0)
'do some stuff here
Next
But it's giving me an error, saying it expects an expression in the first field. But that's what I'm trying to do, loop through the first field. How do I fix this? What would I put in there?
EDIT: to clarify, I'm specifically looking for the 0th element in the subarray of each array, that's why that second field is constantly 0.

I define a arrary.
Dim myStr(100) as string.
Then the length of this array is still 0. Then is risky to cross the bound. So how to intialize this array without using a loop?

I've been looking far and wide to find the answer to my question. Its probably has a simple answer, but I am new to VB2008 and can't figure it out. I have a web form setup 30 textboxes, and am trying to find a way to quickly add them to an array through a loop.Their ID's are all - TextBox1,TextBox2 ect. I have this loop here that runs with no errors, but nothing shows up in the TextBox's on the web form.If the TextBoxes are already on the form, do I still need to declare new boxes when trying to add them to the array?
