Find Total Overlap Percent Of Multiple Rectangles ?
Jun 19, 2012
I've got a list of System.Drawing.RectangleF objects that all overlap the same RectangleF object.In my picture below, the 3 overlapping rectangles would be the pink, yellow, and red rectangles.My main rectangle in question is the light blue rectangle.
Second Image: I know that with RectangleF objects I can use the Intersect() method that will return me another RectangleF object representing the overlap. But as far as I can tell, this only really works when comparing two rectangles.
My question is: How could I determine the TOTAL area/percentage (i.e. the combined total overlap of the red, yellow, and pink rectangles when compared to the light blue rectangle - but it would need to be smart enough to not count the area in which the red and yellow overlaps twice, and same for the pink and yellow)?
NOTE: The green lines represent the area I'm looking for, just the total area of the blue rectangle that is not visible.
UPDATE: I've added a 2nd image to further demonstrate what I'm looking for. In the second image, the presence of the burgundy rectangle should have no affect on the total percent covered because that area is already covered by the yellow and green rectangles.
I am using visual basic 2008 amd creatomg a datagrodview format like below [code] Now I wnat to get total balance in total column after less discount in percentage with ENTER EVENT proceedure and get the whole total column balance in a textbox i.e Net BalanceTextBox. Please tell me how to calculate discount in percent % and get total in total column and also tell me how to move cursor in next cell instead of bottom row in datagridview.
When user stores a record, I need to make sure dates don't overlap.My simple code checks date ranges within a specific record (e.g. user enters 9/16/2011 or 10/21/2011, I throw an exception.)But, on the slim chance a user gets creative (e.g. 10/14/2011 - 10/23/2011 or even 10/14/2011 to 11/16/2011), now they have circumvented my check.BTW, the user could enter 10/14/2011 to 10/23/2011 if they were editing the record that contained values 10/15/2011 - 10/22/2011.So, I'm trying to solve this riddle with a linq query. However, what I have isn't working exactly right.
UPDATE Nevermind about code not working. While trying to provide an example to expand on Miika's repsonse, I found my answer. So, giving credit to Miika for pointing me in the right direction and posting my working code below:
Here's my code:
Private Sub CheckForOverlap(myMonth As Messages.MyMonth) Dim am As New MyMonth() Dim amCollection As Messages.MyMonthCollection
I am suppose to only Find the total of each column in the last row. Find the grand total in the last cell (the bottom right corner)Ok i have tried to do the grandtotal but i am not getting what she wants done I have also tried to reverse the arrays but that was wrong to. I am only suppose to add two line one line is find the total of each colums in the last row and to find the grandtotal.
Module Module1 Sub Main() Dim sum(5, 4) As Integer Dim row, col As Integer
This code bellow to find total of digits from textboxs to listbox.This code don't care about how many textboxs on the form.I take this code from Cazypennie..Great code.My question is..I want to change that code from many textboxs to only one textbox MultiLine having 30 Lines of digits to count and appear to listbox.

The code which is underlined is to be replaced.Instead of this I want to use column name to get the total count , since it contain the total count.Column Name is "TOTALROWCOUNT"
I've just converted a project from .net 1.1 to 3.5, and I'm being given loads of warnings in the error list. The program compiles and runs ok, but I think I should probably try to at least reduce this large number of warnings.The trouble is that the error list only tells me about the first 102 warnings. Even when I fix one, the number stays at 102. So I have absolutely no idea how many warnings there actually are. If there are 150, I'd like to get rid of them. But if there are 10,000, I don't have the time to fix them all.Is there a way to see the actual total number of warnings?
I created one crystal report in that i print time for each user. finally i want to calculate total time. so wat should i do to calculate total time. i tried with sum method......
Protected Sub Calendar2_Selectionchanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles Calendar2.Selectionchanged Dim myDate1 As String = ""
[Code].....
Have to find total days from two date controls after selecting dates in two controls it should print total days by calculating after immediate selection of second date control
I am using vs2005 for developing one project..i have to find Total amount for each page report ( using crystal report and report viewer ..and the report have AMOUNT coloum to display amount) programically..
I'm working on a school project and need some help getting pointed in the right direction. The project is a lawn care application with 2 forms in which the user can select different services they want for their lawn. On Form1 I have 3 checkboxes the user can select: mowCheckBox , fertilizeCheckBox , and mulchCheckbox each with a different price. And nextButton to navigate user to Form2
On Form2 I have a listbox which shows the services the user selected, a totalLabel which will show the total dollar amount of the services, and a calcButton to calculate the total dollar amount.
The problem that I am having is being able to get the total dollar amount. If the user selects the mowCheckBox ($25) and the fertilizeCheckBox ($20) in Form1 I need the totalLabel in Form2 to show the total but cant figure out how to??
Public Class Form1 Private Sub nextButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles nextButton.Click
How do I code the total cost to give me a pound sign with the total cost at the moment when the total comes up for an example it gives me 3.6 when I need it to show £3.60 here is the code I have so far. [code]
I have three Columns of text boxes and I need each column to be added up and displayed in a text box directly below each column with out using a button. The program is a cash counter I already have the code done for multiplying, for example txt1.text = txt2.text * 0.01 (not the exact code) anyway the totals from these is displayed in the columns I was speaking of. I tried the same method I used for multipling but that doesn't work.
I'm trying to overlap two images. I've got this part working, next I needed to make sure it wouldn't carry on overlapping one image. So I did this:
Private Sub PictureBox1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PictureBox1.Click Dim ActualBrick1 As String = "admin_block.PNG" If Minage.CurrentBlock.Contains("wire") Then MsgBox(ActualBrick1) [Code] .....
There's the function. When the file name doesn't start with "wire" it says the correct file name. But if it has "wire" in the name it just makes a picture with the preset file ("admin_block.PNG"). Even if the block under it has been changed.
I need to overlap two images. When overlapped at the correct point, the overlapped portion of both images match exactly (or very closely).Now, I have tried to match the color of each pixel in the images, then move one image a bit and match them again until I get a high match rate, usually 95% or higher. The issue is, this is ridiculously slow. Also, I can't find a way to check the pixels if one I need to check a negative co-ordinate.
For y As Int32 = 0 To bmp2.Height Step 4 If y + StartPos.Y >= bmp1.Height Then Exit For For x As Int32 = 0 To bmp2.Width Step 4 If x + StartPos.X >= bmp1.Width Then Exit For
I'm trying to automate the process of logging into twitterfeed.com, and filling in the information (the feed url and twitter username are pulled from textboxes). I had it mostly working the other day, even if it is a bit sloppy (the only way I could get one button to click is to send 50-some tabs). However, lately it seems to enter in a sort of loop. When I pause the program, Visual Studio indicates that it is the Application.DoEvents in the Private Sub "wait" that is still running even after it should be.
Public Class Form1 Private feed, username, temp As String ' Code stolen off of a website as an alternative to sleeping, or trying to do a timer + while combo like I had been doing
I have many strings in a two column text file. The first column is the start position, the second one is the string.
[Code]...
The second column contains 100 chars.Obviously these strings have overlapped, if a start position is given and the string length is given. How to merge them together? Ex, I want start point is 38781735, end point is 38781900. The string length is 38781900-38781735+1
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

Also the message box, both yes and no close the program.....
I 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:
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 understand the answer in the post above, which is absolutely amazing, by the way. It's about implementing interfaces with a class. However, what if a class needs to share features with another class?Yes, that class can an Interface. However, let's use this sample definition.

Or, in other words:An equippable item can perform acts outside of its typical usage of a shield or weapon. But not all items can act as a sheid or weapon.I mean, I could create a class that implements IWeapon, IShield, IMagic, IUseableItem, etc. But there should be a better way than returning NULL when those interfaces are called.
I'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")
I am trying to have different types of rectangles. I thought something like this would work, but Rectangle is not a class.
Public Class xRectangle Inherits Rectangle End Class
What I wanted this for was to remove a selection rectangle from an existing drawing. I have all of the objects to draw stored in a list and I am trying to remove the selection rectangle without removing the object it is covering.
