[code]what I have done (with some help) is find a timespan. the timespan (between when an employee logged in-out) is, for example, 1:15 (1 hour, 15 mins).the pay rate is 6.00 (representing $6.00)I can't get the program to multiply the timespan by the payrate..Error: 'Conversion from string "02:00:00" to type 'Double' is not valid.'

How can I speed up a process? I see I should use timegettime, gettickcount, and queryperformance counter, but I have no clue where to start.
I guess you can call it Frame Rate or Refresh Rate of a process?

View 3 RepliesI 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?
I need to write a program that uses constants to establish the base pay, the quota, and the commission rate. The Pay menu item calculates and displays the commission and the total pay for that person. However, if there is no commission, do not display the commission amount (do not display a zero-commission amount).
Write a function procedure to calculate the commission. The function must compare sales to the quota. when the sales are equal to or greater than the quota, calculate the commission by multiplying sales by the commission rate. Format the dollar amounts to two decimal places; do not display a dollar sign.
The summary menu item displays a message box that holds total sales, total commission, and total pay for all salesperson. Display the number with two decimal places and dollar signs.
the Clear menu item clears the name, sales, and pay for the current employee and then resets the focus.
The Color and Font menu items should change the color and font of the information displayed in the total pay text box. Use a message box to display the program name and your name as programmer for the about option on the Help menu.
[code...]
So the issue is when I push calculate and summary, the total sales comes up, but not the total commission or total pay. Also, the color only changes to blue and that is it. I am not sure how to get the color or the font menu choices to be able to be choosen by the user. Is that possibile?

View 2 RepliesI have an application that has 3 list boxes, one selects a workshop, the other a location. the third is to display selected costs.to do the calculation a loop is required. i have written the code but when i calculate the cost the final result to be displayed ends up as being the cost of the last work shop and location * 3,What is supposed to happen is the location is multiplied by the number of days(3 in this case) and added to the workshop cost.the loop is supposed to add all cost from the list box till all have been added.what is happening is the calculation goes to the last entry as stated the multiplys this total by number of days(dbl)?

I still want to be able to show my code in front of the class/receive feedback. I originally had a program that would calculate the number of calories in your alcoholic beverage.Because I was new at it, I only had one of my beverages listed. I now want to create a combobox/ dropdown menu so that the user can select a standard alcoholic beverage (I have 6 to choose from). All the beverages have different average calorie counts. Once the user selects their beverage from the menu, they can type in the number of servings they consumed (standard size). They would then push a calculate button and would receive their total calorie count. I have everything up and working but everytime I enter a random number of servings and push calculate, it only multiplies by "100" which is the average calorie count for a serving of Light Beer-- the first listed.[code]
I just added the If/Then/Elseif stuff a couple of minutes ago, hoping it would work, but it doesn't. I know this is something simple but like I said, I'm brand new but I have searched everywhere trying to figure this out. I've watch 9 tutorials so far but they all don't really pinpoint what I want my program to do.
if i had say 10 labels with 10 textboxes how would i save all those labels accosiated with that text box as one text file
say example
label = name ---- textbox1
label2 =surname ---- textbox2
label3 address ---- textbox3
etc
so in the text file it saves it to look like this
name = hayden
surname = doh
address = johnston hwy
How can we multiply the values of the text boxes(reportitems) in rdlc report?
Ex. The expression of TextBoxResult report item is:
=Reportitems!TextBoxPrice.Value * Reportitems!TextBoxQuantity.Value
I'm trying to figure out how to multiply two text boxes but also after they are multiplied, they need to be added at the same time. For example, if in one text box I put 120000 and in another I put .06 - the answer multiplied together is 7200, but the final answer should show 127200.
