By entering a dollar amount and interest rate. I'm trying to figure out how I would evaluate when the dollar amount has been doubled. I already have a do while loop to determine when the dollar amount reaches a million, which works fine.
i have a datagridview binded with the datatable via its datasource property....now i want to add the Amount column of the dgv and display the total amount in the textbox,if the amount is greater than a certain value then i want the cell to coloured red so i did this code and it worked great:
Dim i, j As Integer
For i = 0 To DataGridView1.RowCount - 1
j += Me.DataGridView1.Rows(i).Cells("Amount").Value
Next
[code]....
but my problem is that i want the red colour of the cell to blinkafter every 2 seconds....how to do this?i need to handle the timer tick event for this but i am not able to do this.....
im trying to make a simple program that calculates the time it takes to cover x amount off nautical miles at x amount off knots, the code i have so far is this :
Code:Public Class Form1 Private Sub Label2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label2.Click
End Sub
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
[Code]...
so if i say want to cruise 29 miles at 12 knts it gives me an awnser of 2 hours 24.6 mins instead of 2 hours 25. Although i do realise that 2 hrs 24.6 is technicaly right i was wondering if anyone here could help me with getting it into the correct format?
im trying to make a fast food program on which the user will input the amount that he has, then he will check on what he wants, by using check boxes. There are 7 different check boxes with 7 different amounts of money. I have the program somewhat finished (thanks for the people that helped me before) but theres still a couple of things that I still need to get finished but I dont know how to.I need to be able to get how much money the user has (this will be entered threw a text box, I think I accidentally messed this part up, because I cant get it to work right, (theres alreasy a permit amount of money in there and it needs to be what the user enters instead of the permit, 5.59, one) and this will be the maximum amount he can spend, then the user will check on the food he wants (and the program will add the sales tax also) then it will produce an answer saying if you have enough money or if you dont. But what im confused on is how do I get the users amount of money and make it the maximum mount he can spend and make sure it doesnt go over the amount that he has checked.[code]
View 1 Replieswhen I click the Open button a file is opened and its items are sorted alphabetically. to do this I have doubled the size of my list. However, when I click the button again to reopen the same file, the items will ADD ON to the previous open-file event even though I have this piece of lstListboxTwo.Items.Clear()(the correct thing is to clear the previous items and add the new ones)So I think this has to do with the new size of my list..I think that I have to set the list size back to its normal size when re-clicking on the button.

Dim List() As String = {""}

View 17 RepliesI'm having some difficulty formatting some of my strings, I can't see what's wrong unfortunately. I have various numbers, e.g. 100.023, 13488.323, etc in a datagridview column that I would like to be formatted so it looks like this: $123,456
Here's what I've tried so far (that isn't working):
row.Cells(1).Value = Format(row.Cells(1).Value, "{0:D0}") 'I've also tried using {0:C0}
row.Cells(1).Value = row.Cells(1).Value.ToString("$#,#")
'This one (above) comes up with an error saying it can't put an "##" in an Integer column, something like that anyway.
I'm trying to get the Subtotal, Sales Tax, and Total to be displayed in currency form, (i.e.: $0.00). The form:
Private Sub CalculateButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CalculateButton.Click
Dim PartsCharges As Decimal
Dim LaborHours As Decimal
[Code] .....
Is there some easy line of code I can do to format it? I know how to do it the .ToString("C") way, but that doesn't work in my case, because they are text boxes and don't have any declared variables for the numbers that are inputted inside of them.
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 the pay/calculate button everything is calculating correctly the first time, but then when I push clear to input another workers name and weekly sales and push calculate, my label is blank and does not display any info about the second worker. Then when I push summary after inputting the second worker, it's only displaying the total calculations of the first worker. I can't seem to figure out this problem on my own (After countless hours staring at my code I might add!), so I am hoping somebody can pinpoint what I have done wrong? EVerything else is seeming to work just fine.[code]...

Does anyone know of a way to script falsifying the amount of RAM installed on a PC for an install. I have a program that needs to be installed on many systems that all have little RAM. The program requires during the setup that at least 384 MB of RAM be installed. Some of these systems only have 256 so the install fails. I know the easy answer is install more RAM. Ain't going to happen. Company has no budget. The install should be fine I think, but would like to test more. in order to do the testing to see if this would even work though I need to figure out how to have the OS tell the app it has more RAM than it does. I don't know this app but my first guess is the app queries WMI for amount of RAM?? If that's the case is there a way to set that WMI entry to something different until after the app is done? Or if someone knows another way that would be good too?
View 17 RepliesI need to induce a variable amount of lag in vb.net. System should be noticeably slower. I can raise the CPU usage of the program with infinite loops and some variable creation/assignments, but how can I actually cause lag? I'd like to have an "InvokeLag" sub which will perform an action to slow down the computer, the faster the function is called the faster it lags. The function should be as mundane as possible, not modifying anything or doing anything to cause damage other than simple lag.

View 9 Repliesi need to reduce an amount of time by x% this is what i have so far [code] as u can see ive taken the hours minutes seconds from the time and stored each in a seperate variable so from 02:30:00 i then divided the hours by 60 and then 60 again to give me the total seconds in the hours and then divided the minutes by 60. i then added all 3 to give the total amount of seconds so now the buildtimetotal variable now holds the total in seconds i now need to reducce this by x% all vars are dimentioned as integers except for buildtimehoursback which is a double the problem seems to be when i try to convert the total seconds back to hours minutes seconds.
