how to add multiple text to a point pair list in Zedgraph. Add text to one point pair can be done like this:
Dim myPane As GraphPane = zg1.GraphPane
Dim TextObj As New ZedGraph.TextObj("High", 10, 10, CoordType.AxisXYScale, AlignH.Center, AlignV.Center)
[Code]....
Theres a problem with the code above when the graph scrolls the text is following as it should, but it's also visible in the pane background.
Is there such a thing as a type similar to a point, but contains a pair of decimals, or a pair of doubles, rather than integers? I searched the forums and google with no luck. I can't believe this has never come up before, I must have been using the wrong search terms.
View 4 RepliesI have a table with 2 rows named timeStamp and value. I know I can iterate through the rows and create points and add them to a list (new point(timeStamp,value), but is there a way to do it without iteration?
View 11 RepliesI hve been working with points a lot recently, and I have been wondering if there is a way to set a point without setting point.x and point.y separately. For example for (3, 5): Point1 = (3, 5) But that isn't right
View 4 RepliesI'm trying to extract a piece of text from within the string, defining both a starting point and an ending point. For instance, say I want to search for the text found between "That is a " and " car" in the string "That is a red car", so it would return "red".I know you can use .SelectionStart and SelectionLength, but the length of the word can change, so the selection length can vary. What I want is to establish a specific starting point and a specific ending point from which to extract the text from the string.
View 5 RepliesOk so im looking at this code and it cant possibly be right but im not sure how to do what i want.I have made a list of n points. I now want to click a button on my form and use the picturebox paint event to draw my lines between the points in the list.From what i can see i have at least two issues with this code. 1. Nowhere in this snippet do i reference the picture boxes paint event 2. I do not think that the loop i have is how to navigate through the list of Points to make my drawings.
View 14 RepliesI am using the following Caml Query to get data from a share point list.
oSb.Append(" <OrderBy>")
oSb.Append(" <FieldRef Name=""Title"" />")

But this query is giving me all columns of list. Is there any way to get only desired column from a share point list using Caml Query?
I have a list of collection of points on the screen. I want to order them based on their distance from a seperate, independent point. What's working is I have a function GetDistance which does the dirty pythagorian work of returning the distance between two points.
'Create the set point from which to start all measurements from (startpoint)
dim SetPoint as new Point(200,200)
'Create a list to hold arbitrary points to test (endpoints)

how to remove text. For example, I am trying to get the username of the logged on user (e.g. Bryn)into a variable. I did this with variable = My.User.Name
However this also brought the domain with it (e.g. aaabbbcccBryn).
Is there anyway of getting rid of the domain? The App will be used on many domains, so removing the first, say, 9 characters won't be any good.
I want to know if its possible to loop in a variable and grab info from point a to point b
This is what I have stored in my Variable

I'm working in a program that need to do the following.An airplane has 15 rows (1-15), with six seats (A, B, C, D, E, F) in each row. I need to write a program to display the seating chart in a list box, when the person clicks on the desired row in the list box, the row number and the status of the seats in the row are displayed in seven read-Only list boxes.Now, I know how to create a listbox and the make the text boxes, my problem is how to display what is in one row into 7 text boxes.Then the person click on any of the text boxes a second form with 4 radio buttons is poping up. This form will have the status of the seats, (Unoccupied, Low Carb Food, Vegetarian and Regular) if any of these is selected will change the status of the seat at the listbox and the text box..Should I use arrays to fill up the listbox and redim when update is require?

View 14 RepliesThe following code checks each sentence in the listbox and if certain conditions are matched it add a piece of data to the list new question. Each input from the user is checked against each sentance in the listbox and if a match is found (based on the conditions) only then the data is added to the list and the loop exits. My problem now is that for each itteration cycle In_dep_token_pair.Key and trigger_dependency_token_pair can not be Subject and DirectObject at the same time. Is there any way to test for the next item in the keyvaluepair within the same itteration cycle? Something like trigger_dependency_token_pair(current item).Key = "Subject" and trigger_dependency_token_pair.key = "DirectObject".
If (Input_pair.Key = predicate) And (In_dep_token_pair.Key = "Subject" And trigger_dependency_token_pair.Key = "Subject") And _
(In_dep_token_pair.Value = trigger_dependency_token_pair.Value) Then
If (In_dep_token_pair.Key = "DirectObject" And trigger_dependency_token_pair.Key = "DirectObject") Then
If (In_dep_token_pair.Value = trigger_dependency_token_pair.Value) Then

btw.. as its a save file type thing the text is not going to be the same as above that just to get my point across to you but the "point of change" (####)
First, the overall objective is to find the best point within a multipoint filled 'star', at which to start drawing text. That is, depending upon the size of the star and the number of points, there is a larger or smaller area within the points that is filled with colour. So a 5 point star has a relatively small area that is filled, in which to draw text. A 40 point star of the same radius has a much larger area filled. If I can determine the size of this area as a rectangle, then I can measure the string and draw within it using the best fit font and starting position. The code below is an attempt to answer the question but I am stuck trying to find the text area rectangle within the filled portion of the star. Some of the code exists purely to explore the means to determine how to identify this rectangle (and is probably the totally wrong direction).
The second part of the problem is in exploring the options, I tried to draw a vector to different points on the circumference of the star. This is the code highlighted. The lines drawn do not seem to be the correct length nor the correct angle but I cannot see why.[code]...

I was wondering if it is possible to point to a textbox created in the form designer via a string variable. Basically, I'm creating a golf management system with a feature allowing a user to define their own course. Each hole has a corresponding textbox into which a user can input the hole's par and then the system should total up the first 9 pars, the last 9 pars and then all 18 pars; displayed in 3 different textboxes.
The input textboxes have been named txtP1, txtP2, ..., txtP18, so I was wondering if I could simply concatenate a loop control variable onto a constant of "txtP" to point to each input box.
This is what I have at the moment, but it's throwing up errors saying that .text is not a member of string.
Sub UpdatePar()
Dim inpar, outpar, totalpar As Integer
Dim pointer As String

In my VB.NET code behind, I've created a multiple name/value pair cookie like this:
Dim UserCookie As HttpCookie = New HttpCookie("UserInfo")
UserCookie.Values.Add("UserNumber", Me.UserNumber.Text)
UserCookie.Values.Add("Password", Me.Password.Text)
UserCookie.Values.Add("UserName", Me.UserName.ToString)
Response.Cookies.Add(UserCookie)
Now, what I need to do (somehow) is read that 'UserInfo' cookie in javascript and be able to extract those values at will. Most of what I'm finding out there doesn't quite do what I need to do.I'm trying to do something like this:
var MyValue = ReadCookie("UserInfo", "UserName")
And MyValue would equal whatever the user had typed into the textbox.
Normally when I populate a combobox I do so by binding it to a datatable and assigning a display member and value member. I would like to do the same thing by adding pairs of items in code.I tried using a key-value pair, but that didn't work. The combobox displayed both the key and the value. I would like to have it just display one of the values and leave the other one invisible to the user, but available to me as a key.I thought about creating a custom class with two properties - one to use as the display member and the other to use as the value member. But before I re-invent the wheel I thought I'd check to see if there's already something there in the framework that I'm missing.
