I have made an countdown app that is working in a normal way (added picture of it). Now when I select a number in the numeric box and click start, it starts to count down from that many minutes, but what I want is the number I put in the box *3. So if I put in 3 (points) the counter will count down 9 minutes. If it is possible I want a counter at the bottom every 3 minutes the value of the 000 at the bottom of the image multiply by 1 (+1 for every 3 mins timer1 runs).

I have a requirement that regardless of the start and dates that I need to loop through that timespan and calculate figures at the month level. I cannot seem to figure it out, and maybe it is not possible, but I would like to do something like:
FOREACH Month As TimeSpan in ContractRange.Months
Do Calculations (Month.Start, Month.End)
NEXT
Is this possible or do I need to calculate the number of months, and just iterate through the amount of months and calculate the start/end of that month based on my index?
Dim result as single = 0
result = CType("8.01", Single) * 100 ' result=801.0 as expected
result = CType("8.02", Single) * 100 ' result=802.000061 --- not expected
Further to the above
result = 8.02 * 100 ' result = 802.0 as expected
I am very new VB .NET and just starting If statements. My problem is: Write an If statement that determines whether the variable CurrentBalance is greater then 1000.01. If it is, multiply the variable CurrentBalance by 1.005. Otherwise, multiply CurrentBalance by 1.007.So far I have
Sub Main()
Dim currentBalance As Boolean
System.Console.WriteLine("Enter Current Balance: " & currentBalance)
If CDbl(currentBalance) > 1000.01 Then

I really don't even know if thats how I should be starting. Not sure what to put after the first Then on how to make it multiply currentBalance by 100.5.
This is part of a calculator program. I first part I sort by num and sign using a multitude of commandbuttons with no parenthesis.This program below is part of the second part. I have three more subroutines for /, +,- respectively.The + and - work correctly but * and / do not.I think it is in the line: numop(m) = g * h Is there something I am doing wrong wth the syntax in multiplication?
Public str, sign(100), numstr(100) As String
Public num1lock(100), m, n As Integer
Public ans, num(100), numop(100), g, h As Long

I have an assignment to make a multiplication table using loops. The idea is to make this: If the user enters 3 this is the result he gets:
0 1 2 3
1 1 2 3
2 2 4 6
3 3 6 9
if the user enters 5, this is te result:
0 1 2 3 4 5
1 1 2 3 4 5
2 2 4 6 8 10
3 3 6 9 12 15
4 4 8 12 16 20
5 5 10 15 20 25

I'm new to VB and programming in general and have not had too much trouble however i cannot figure this problem out and i've been working on it for a week. basically i have to create a program that calculates the mass of someone on another planet with the conversion numbers as constant, an input box for the user's mass, using select case format and output to a label including the name of planet ie "Your mass on &strPlantet is x" so what happens is my intWeight variable becomes zero and the lblResult is Zero. (i have not added the all the code for the label output) oh yeah i must also use a try/catch structure to prevent non numeric data from being input.[code]

Simple Calculator multiplication and division Trying to make a simple calculator. My program inputs numbers and arithmetic operations thru commandbuttons. The numbers, num(n-+1), are odd and the operations, op(n), are even. The code is based on the even op string. Every time a op occurs it is stored in numop(n) to be accessed later. I have all the other operations in sequential order: "*"," "/, "+" and "-". The other similar For-Next loop are the same just interchange the two * for /, +and -. The "+" and "-" work fine in this configuration.
My problem is the multiplication and division does not occur. The numbers and operations line up. The numop(m)=g*h should yield numop(m)=num(1)*num(3). Is there some sort of code to be inserted to accomplish these multiplication and division operations?

View 4 RepliesI know about VSTO/VSTA, and I also know that some VBA functionality (with .NET syntax of course) can be done in .NET. There is definitely a learning curve going from VBA to .NET without VSTO. My question though is, can everything that is done in VBA somehow be recreated in .NET without VSTO?
The reason is because I am converting my VBA application into .NET for several reasons: I want to take advantage of OO, my class libraries will be better available for use, and for fun. I wouldn't be too happy if I got so far in only to learn of some limitations.
If I have code like this (C# or VB.Net does not matter)
Dim e As IEnumerable(Of XElement) = _
From s In _dataSourceSettings.Elements _
Where s.Attribute("name").Value = toInsert.Attribute("name").Value
If e.Count > 0 Then
e.Remove()
End If
How do I get now new _dataSourceSettings without element that I removed?
I am writing a INSERT Statement which will INSERT data into a Access 97 DB.Everytime i run the Statement from my VB.NET Code i always get Error in INSERT SyntaxI have narrowed it down to one DB Field - INSERT INTO TEMP (Size) VALUES ('" & varSize & "') - I have taken all the other variable out.
Is the fieldname "Size" a reserved name or anything in Access 97 and is there a way round this so my whole statement will work including the Size part?
I have some old VB6 code which was written by someone else who is doing the same insert but instead of INSERT they have created a VB6 RecSet and set all the values then used RecSet.Update to insert the row of data. Is there a VB.NET version of RecSet and Update.
I am writing a program that rolls those crazy many-sided dice for use in fantasy games, and I have come to a point in my work where I am completely stumped. I am hoping that some of the more seasoned VB programmers on these forums might be able to point me in the right direction.
If this explanation gets a bit lengthy, please forgive me; I tend to be long winded. The feature I am trying to implement is that every roll result can have one or more "damage types" associated with it, such as "Fire" or "Acid". If I rolled a dice with "Fire" as the type, and the resulting dice roll was a 4, this would result in an output string of "4[Fire]". If there are more than one type, they are separated by commas like "4[Fire,Acid]".
The problem is when performing math while keeping track of these types. For addition and subtraction, there is little problem, "4[Fire]" added to "4[Acid]" is simple "8(4[Fire], 4[Acid])", while "8[Cold]" minus "4[Fire]" will leave "4[Cold]". Still with me? The problem comes into play when we multiply or divide rolls with types together. If we multiply "4[Fire]" and "4[Acid]", we get "16[Fire,Acid]" which is different than either "Fire" or "Acid" alone. Similarly, if we divide that "16[Fire,Acid]" by "4[Fire]", we are left with "4[Acid]", but if we divide by "4[Cold]" instead we will have "4[Fire,Acid]"
So how do I go about keeping track of this? Some of the dice strings my parser can handle might have dozens of damage types that might need to be figured into the total results. The result should display the total for the entire calculation, with results per damage type tracked separately. Currently I am using code that parses the string data above so that every type name is stored in an array with a integer variable associated with it for the total of that damage type. So, for the string "4[Fire,Ice]" I am storing the info in a variable that holds the 4 and an array that holds "Fire" and "Ice".

View 3 RepliesI have a program that has the option to create a restore point. My problem is that when you click on it to do so, the program just locks up until it's finished creating the restore point. I have put a separate form on the program and it has a Marquee Progress Bar Control which I downloaded, so the idea is.
User clicks "Create Restore Point"
frmRestore.show
Marquee Progress Bar goes on and on while the restore point is created
Restore point is done
frmRestore.hide
The thing is, when you click create restore point, the form shows and the program just locks up, onces the restore point is created the form hides again. Could this problem be solved with a Background worker? To be honest I'm not completely sure what it does, I mucked around with the controls but can't seem to find anything useful.
