Loop Through Top Level Folder In Mapped Drive And Give Total Count Of Files And Total?
Oct 28, 2008I am working with VB 2008. I want to be able to run this program say in N: and it will show me in an excel sheet the following:
Folder Path Size(GB) Count of Files
N:Clients 0.53 308
where clients contains subfolders and files and the size is the total of all those files within each folder and the count is the total within each folder also.
This works fine as it is but i have to select one by one the top level folders and some of them are huge so it takes forever to give me an answer.
1) I would like to see in my spreadsheet the following by only select the network drive n:
Folder Path Size(GB) Count of Files
N:Clients 0.53 308
N:Software 10.7 15430
N:Billing 0.98 105
2) I would also like to know if this is the faster method.
3) I tried adding a progress bar so that the user can have an idea of how much this will take but i had to remove because it was not working.
4) I would like to see the folder name, size of folder and count of files in the listview.
Here is the code:

Add Data From One List Box To Data From Another List Box To Get A Total?
Oct 5, 2009how to add data from one list box to data from another list box to get a total. My application has to have three list boxes. One list box contains a list of workshops a user can take. Another contains a list of locations the user chooses from to take the workshops at. When the user clicks an Add Workshop button, the application should add the total cost of the selected workshop at the selected location in the third list box. My problem is that each workshop last a different amount of days and each location charges a per day fee. I'm not really sure how to add all of this information together to come up with the total workshop cost. I think I should use a Do While loop. Another problem is that after the total cost of the workshop is added the user should be able to click a total cost button and get the total cost for all workshops they have selected.

Use A Loop To Sum Until Cumulative Total Equals A Specified Figure?
Apr 29, 2010I am trying to filter a dataset by adding together numbers within a specified field (say field1) within the dataset until i reach a specified number.
The filtered dataset should either be precisley equal to the number or most likley less than. In short if a row exceeds the number it should revert to the previous record.
I have no probs with general filtering and using data adapters to access the data. But im struggerling with the loop side of things.
Using Loop - Showing Total Cost And Adding Indexes Together
May 5, 2009I have a class project that I have been working on for a while, and I can't figure out how to add each cost from lstCosts together to show a total cost of the selected workshops in lblTotalCost. Using the current loop that I have, it only adds the last cost in lstCosts. Is there a way to add the indexes together?
Code:
Public Class Form1
' The registration fee for each workshop
Const intSTRESS As Integer = 595 ' handling stress
Const intMANAGEMENT As Integer = 695 ' time management
Const intSKILLS As Integer = 995 ' supervision skills

View 2 RepliesDetermine If Property Is Generic List<of T> Via Reflection And Loop List Items
Oct 1, 2009I'm looping all the properties in an object via reflection:
For Each p As PropertyInfo In values.[GetType]().GetProperties()
If p.CanRead Then
'Do stuff
End If
Next
how to determine whether the property in question is a generic List(Of T)? If it is I need to loop the list itself.
I've experimented with GetType and TypeOf but have not managed to get anything working.
To clarify, I want to keep this generic. I do not want to specify the type of T, I need to loop the list items and call the ToString method on each item. T could be one of a number of different types (application specific reference types). Is it possible to do this without specifying types?

View 2 RepliesPayroll Calculator - Program Must Calculate And Display The Total Pay In The Total Pay Label
Oct 6, 2010The pay rates for the project are:
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.

View 1 RepliesFour Forms And Grand Total - Adding Data From MSAccess2007?
Dec 30, 2010I have four forms only. The first one is the main menu, that contains three buttons, the first and second buttons go to form2 and form3;Button 3 should open a new form (4) and to write there just the total price.
In Form2: DataGrideView that contains a table made by MS Access 2007. That table contains only two columns and three rows. When you select the item, the price of that item should be saved to be added to the other selected items
In Form3: ComboBox that contains another table also made by Access2007. The same thing, the table contains two columns and the selected item has a price that should be summed with the first selection in Form2.
My Questions are:
1. What I did by adding data from MSAccess2007, is it right?First: View -> server explorer -> Browse(my database) -> Test Connection --> OK ...Second: Data Sources --> Add new database --> etc Third: I dragged one table and put it inside Form2, then the another table to Form3.Is that all right? <--- This is my first question.
2. Now, is, what I have done in step 1, enough to pick up the price of the selected item(s)?if not, what is the code that I have to write to make this connection, and where?
3. As I said, when I click on Button3 in Form1, Form4 should appear and give me the grand total. How I can write a code that makes this summation, and where?

Adding Another Total To An Existing Total?
Nov 21, 2009I'm new to forums as well as new to VB 2008. I'm in process of making a order calculator which will total any values you selected in combo boxes/checkboxes and then display it in a selected area. There are 3 things that I want to achieve: 1. Be able to add another total to an existing total (currently I'm able to see only one total when I hit "Calculate" button)2. Display how many orders I have made so far (new total counts as one order)3. Be able to add up checkboxes selected to an overall total. (when I try to add up one checkbox with another it seems to be stuck on 1.5 pounds which I assigned for each "side order")
View 4 RepliesBGWorker Woes.. How To Loop A List?
Jan 6, 2012i have a list that has things that needs to be looped. This list can be up to 500k items.I would like to add a multithreading option with a variable. This is not an issue, as I know how to make multiple bgw's (Code below)
i = spin_NumOfThreads.Value
Dim bgwrks(i) As System.ComponentModel.BackgroundWorker
For Each bgworker As System.ComponentModel.BackgroundWorker In bgwrks[code]....
so in that code, it'll make the number of threads based off of my spineditor.Now, ideally i'd like it to go through a list, each thread does its thing.Now, a simple dowork would just allow it to do 1. i would ideally like it to stay @ X threads until the list is done, so how would I basically go about remaking a thread once it finishes to continue? So, lets say I have 50 items in a list, i set the number of threads to 5.The first 5 would do the first 5 items, when the 1st one finishes, it works on item 6, then the next would do 7, etc. and it'd keep remaking until 50 is done.
