I have a text box in form1 that displays the total, I want to carry this over to form 2 into another text box as I navigate between them, how would I do this? Also I have a button on form2 to return to form1 but I need all the data that has been input by the end user to be cleared from both forms when returning, again how would this be completed?
I want add a Total textbox to every form.The total will add the values that will be entered in the montant textbox. So the total will take the specific value of that texbox for all the entries that the user will have and add them. How I can do so?
Ive got a Listbox which displays a data/record from a SQL database, it displays "Amount" and only numbers would appear. it has a datasource.
Goal: I'd Like to get the total sum of those numbers from the Listbox and Display it to a textbox automatically or by button click event.
I thought of two ways to do this, but I don't have a clue on what to do.
1. I tried summing it all up on that exact Listbox and display the total on the textbox, here's the code that i came up with..
[CODE]...........
But the data im working with is from a database, so i got this error:Conversion from type 'DataRowView' to type 'Double' is not valid.
2. I thought of having another Listbox and "Copy" the contents shown on the Listbox1 and then sum it all up on the Listbox2, then lastly display the Total on the Textbox. I did a little research on how to accomplish that but all the clue i found is that i have to disconnect the listbox data from the datasource from being bound, and reconnect it again.. I really don't have any idea on how i could do that with an SQL database.
Here's a quick flow on what im trying to accomplish to make things.
Record from Database -----Displays on---> Listbox1 -----User Clicks--> Button1 ----Displays Total sum on----> Textbox1
I am trying to create a textbox that will display the total duration of all video files in a listbox. I am not using the windows media player in the project, I just want to show total duration of the listbox items. I have tried looking for snippets because I'm new to programming and I have also tried my luck at creating a class with no success. If anyone could show me some sample code or tell me what it will take to accomplish my goal it would be greatly apperciated. I am coding with Visual Basic 2010 express.
a. Level 1 - $10.00 b. Level 2 - $12.00 c. Level 3 - $14.00 d. Level 4 - $16.00 e. Benefit Deduction Rate - 0.10 f. Overtime Factor - 1.5
For ease of program maintenance, all of the above rates and factors must be stored in module level constants. All references to pay rates in the program must refer to the module level constants.
When the Calculate button is clicked:
a. The value in the Hours text box must be validated to insure that it is numeric value greater than zero.
1. If the value is not valid, a message box must appear as shown below and the user must be offered the option to continue processing or quit the program.
2. If the user chooses to continue processing, the focus must be set to the Hours text box.
3. If the user chooses to quit, the program must close immediately.
b. If the value is valid, the program must calculate and display the total pay in the Total Pay label.
1. The pay rate is determined by which Job Grade radio button is checked.
2. For hours less than or equal to 40, the total pay is the hours times the pay rate.
3. For hours greater than 40, the total pay is 40 hours times the pay rate plus the hours in excess of 40 hours times the pay rate times the Overtime Factor.
4. If the Full Time radio button is selected, the total pay must be reduced by the Benefit Deduction Rate.
5. The value displayed in the Total Pay label must be formatted with a dollar sign and with two decimal places.
6. The focus must be set to the Hours text box.
Why i get an error when i try to run this code
Code:
Also the message box, both yes and no close the program.....
I have three forms similar to the one in the link. I want add a Total textbox to every form. The total will add the values that will be entered in the montant textbox. So the total will take the specific value of that texbox for all the entries that the user will have and add them. [URL]
I have 3 columns in a unbound datagridview, "length" "height" and "Total". Total = length x width and the final total in TextBox outside of the Grid. I found question simalar in this forum and tried the code but i am getting errors.The following is the code i am using
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

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.....
I have a database I am creating with about 50 users over a network. There are about 6 groups of users and these users are spread across 10 branches. I want to block/allow users from particular forms and views. For example I want branch users forms to be filtered by their branch number but depending on the group they are in they can only see some forms. i.e. 50 users, 10 branches, each branch has about 5 ppl of where 1 is in group A and 4 are in group B. I want all users that belong to branch 1 to see the information they enter, but Group B enter data but cannot approved or delete, and group A can enter, approve and delete. So then. On my login form I have the user type his/her username but the i want LEAVE function to update 2 textbox where I have named GroupName and BranchNo. Basically to run a query and look for the username and return in one textbox that user's groupname and the other textbox the user's branch no. This information will be used to filter forms and block the user from certain controls. This is the code I have so far but still can't figure how to display the results.
Private Sub UsernameTextBox_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles UsernameTextBox.Leave 'Make Connection to database
[Code].....
It keeps highlighting the BranchNumber and UserGroup and giving error "Value of type 'String' cannot be converted to System.Data.OledbCommand
I'm looking to write a very simple program which asks a user to enter a number between 20 and 50. The program would display the letter 'I' in a textbox to correspond to the number the user entered (i.e. if the user entered 34 then 34 I's would be displayed. I'm not entirely sure of what commands would make this happen.
I use the following coding to display some data in a rich text box, I have some additional coding which checks for duplicates, sorts it etc.However would it be possible to only display the first column? My columns are separated by a space (" ").
richtextbox1.Text = System.IO.File.ReadAllText("Path") Dim LinesList As New List(Of String) LinesList.AddRange(richtextbox1.Lines)
Console.WriteLine("Network adapter: {0}", adapters[i].Name); Console.WriteLine("Status: {0}", adapters[i].OperationalStatus.ToString()); Console.WriteLine("Interface: {0}", adapters[i].NetworkInterfaceType.ToString()); [Code] ..... What I want is to have this Console.WriteLine displayed in a text box on the form but how to do it.
I am receiving RS-232 data from serialPort1.Readbyte and want to display the incoming data on a textbox on a form. This causes a "...cross thread..." error.
I'm trying to display the total extraction progress of a zip file as below. This gives me the total file size of all uncompressed files in the zip: For Each backup In zip TotalSize = backup.UncompressedSize + TotalSize Next
I'm then using this to get the current bytes transfered: TranferTotal = e.BytesTransferred + TranferTotal
The problem is this value resets after each file is extracted from the zip. I was expecting the above to "tally up" the total so I could use it for the progress bar but it seems to still reset after each item? Also, I'm using a global varible for the transfer total, if there a better method to transfer this information to the StepEntryProgress? The reason I'm doing this is because the DotNetZip Library does not support multiple extraction in this way, so I need to tally up in this way.
Code: Imports Ionic.Zip Imports System.Threading Imports System.ComponentModel Public Class Form1 Dim TotalSize = 0 [Code] .....
This should calculate and display the total amount due. There are 3 radio buttons, A, B, C. Nonprofit should get a 20% discount from final charges.
