Multiplying Without Using A Button?
Apr 9, 2011I'm new to vb and I am currently trying to code a Program for counting cash from a till. I know how to multiply and add if I were to use a button to execute it but what I want is for the totals to be automatically populated as soon as the user inputs the data.
Example:User inputs 23 into the txt1cent textbox
So the program should multiply 23 by 0.01 and output the answer (0.23) into txtsum1cent textbox.

View 6 RepliesMultiplying Odd Numbers In Sequence Using MOD Function?
Jul 2, 2010Then you have to take that same range and find the product of all odd numbers between said sequence. I figured out how to find the product but only if the lowest number is also an odd number. For example, if I put in the values 1 and 7 the product is 105 which is correct. But if I put in 2 and 5 the product somehow becomes 10, when it should be 15.I have to use the MOD function to distinguish between even and odd numbers, which I know how to do however it's still not working out correctly for some reason and I'm completely stuck. This is the part I'm having trouble with. Go down for full source)

Multiplying Two Or More Lines In Two List Boxes?
Oct 7, 2009I have two list boxes created. They are populated when I enter the quantity and the price (one list box for each). This data actually comes from another set of text boxes. The problem is when I have two or more items in each list box I'm unable to come up with the total. I need to take the quantity * price for each entry and then add that to the quantity * price for the other entries. When I press my "total" button it's only doing the calculation for the first line.

Setup A Function Involving Multiplying A Cell By A Set Number And Then Having The Result Round To The Nearest 10?
Apr 22, 2009I am working in excel trying to setup a function involving multiplying a cell by a set number and then having the result round to the nearest 10.

Passing Multiple Byref Variables / Variables Fail To Change Calling Funct W/ Invoke
Sep 27, 2010I have code, shown below, that works all except for 1 thing: The variables being passed byRef get passed, but once modified in the else section of the "if me.invokerequired" code of RecordData, the variables are never updated in the calling function. To reiterate, the calling function does not receive the updated data that is in the variables custid and amt.When debugging, I see the data change in the else section of "if me.invokerequired", but once it returns from the callback the data is missing.[code]
View 15 RepliesDefine Some Global Variables Of A Class - Variables Occupy Memory?
Mar 23, 2012I define some global variables of a class as follows:
Private Class MyClass
Private var1 as Decimal
Private list1 as List(Of string)[code].....
But I found that after this form is closed, all above variables, var1, list1, list2 still exist in memory. I thought they should be collected by gc since the form is already disposed as I confirmed.
Add: I have monitored half an hour after the form is closed. But these variables are not collected by gc. I have an automatic update procedure on the form which uses above variables.Since the above variables still hold values, the automatic update procedure is always called which causes exception. (One quick fix is to check if form.isDisposed in update procedure. But I do not think this is elegeant. Besides, these variables occupy memory.)

Mar 8, 2011Question 1: What is the difference between "Background Worker" and "Worker Pool" as indicated within the MSDN samples provided.
Question 2: I noticed while using, AddressOf _Function_, variables cannot be passed; what would be an efficient solution to this?
Question 3: While using multithreading is it required to invoke before setting variables, or only form properties?
Question 4: While using System.Net.Sockets is it safe/efficient to use Application.DoEvents while waiting for new data; or would be using a Do While loop be fine without DoEvents since the action would be multithreaded? Note: there can be up to 2000-3000 sockets in use at a time.

Possible To Use Variables Without DIM?
Jul 10, 2011Is it in VB.NET possible to use variables without the need of use DIM? Now I have to use the variables like this:
dim a = 100
dim b = 50
dim c = a + b
I want to be able to use vars in this way:
a=100
b=50
c=a+b 'c contains 150
I think in VB6 and older VB this was possible, but I am not sure.

Asp.net - Using Session Variables In IE?
May 14, 2012I have an ASP.NET application that I am developing. I'm using session variables within the app.In Firefox & Chrome, they all work.But in IE (ver 9), there's one variable that's not working. I'm not sure if it's a storage or a retrieval (or both) at this point. The variable in question that I'm storing is a List(T) type. It's the only one of it's kind that I'm using. Can't help but think there's a correlation there.One other old post mentioned the possibility that cache is causing the problem, but I didn't understand the answer very well.
