I have a WPF grid made out of labels with two rows, Apples and Oranges currently without any information. Let's say I want to populate the grid to look like the picture below.
I was wondering what's the best way to populate the labels with a list or array? I was thinking about using a list and passing values into the list
E.g.
List <string> ApplesList = new List<string>();
ApplesList.Add("Red");
ApplesList.Add("Delicious"):
List<string> OrangesList = new List<string>();
OrangesList.Add("Orange");
etc...
But I was wondering it make sense to use a list. Or should I just use an array or 2D array?
Sometimes I wonder when would be best to use a list, array, or 2D array.
Each Element named Bookmark has 4 attributes, Name, Folder, Time, and Chapter.
I'd like to be able to just put all of them in ONE type of container, without making multiple lists... Is there any way, using Linq to XML, to maybe add all of these values to a Tuple?
I'm attempting to write a program that displays an array of labels; however, I can't seen to make the labels appear in the form. I've set some of the properties, but still not luck.
Code:
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text;
// prompts the user for a non-negative numbers (>= 0) // reads in the a number and checks // keeps re-prompting user if the input is invalid (negative)
[Code].....
How do I go about Populating the elements in the array created, I keep getting a compiler error on this vArr[i] = tmp_stream.str.at(i);
I'm dynamically creating some labels. This code creates them OK.
panel1.Controls.Clear(); for (int i = 0; i < 5; i++) { Label label = new Label(); label.Top = (30 * i) + 20;
[Code] ....
Now, after I'm done with them, I'd like to delete them but my code below skips each of the two forloops, so nothing happens. The labels are still on my form. When I debug into this code, I stop on the first forloop and then I step but the flow never goes into the forloop. It jumps to the next forloop where the same thing happens.
List<Label> itemsToRemove = new List<Label>(); foreach (Label label in Controls.OfType<Label>()) { if (label.Tag != null) {
How you can touch a datagridview and it would insert the name it has for a product into a label or textbox.... As I have looked all over and I can't really find a proper way it is mentioned or maybe I am not applying it correctly.
The program is when a person clicks a button this button updates 2 separate listbox one tracks the total rolls the other displays the total amounts of frequency afterwards adjusting labels as a scaling measurement.
The problem I am having is right at the end where I am trying to adjust the width of the label this is what I have. It is highlighting the word "Items" for each label and says that Non-Invokable member 'System.Windows.Forms.ListBox.Items' Cannot be used like a method L2 is a label. Additionally I have added in the information for one of my loops below the line I am having trouble with this loop is created to determine how many lines are in the listbox of rolls and I have no trouble with this just thought id add it for additional information I dont think I need to add the rest of the code but I can if needed.
L2.Width = int.Parse(lstfrequency.Items(0).ToString()); TL = 0; for (I = 0; I <= 10; I++) { TL += int.Parse(lstfrequency.Items[I].ToString()); } lstfrequency.Items.Add(TL);
Is there such thing as passing a winforms label by reference? For example, can I create a pointer label and pass the address to a function? I've looked online but couldn't find anything. Perhaps that's a sign?
I am attempting to create multiple labels in a for each loop for each tag text (using htmlagility pack). My current code only creates one and doesn't change the first value (Which is AAE). I am using the labels to later input all the label.text into a database after the initial loop has finished (not shown).
foreach (var tag in tdTags) { MessageBox.Show(tag.InnerHtml); Label label = new Label(); label.Name = "contentName" + tag.InnerHtml; label.Text = tag.InnerHtml;
I am trying to get a datagrid working in my program with populating a simple set of data. Which i can then expand on and bring in data from a database.
But even this little simple test datagrid does not seems to be working.
ive added the HTML code to set up the datagrid, which i can see via design tab, but filling it up is harder.
i uderstand it needs a
protected System.Data.SqlClient.SqlDataAdapter sqlDataAdapter1; sqlDataAdapter1.Fill();// where it require a dataset or datatable DataGridProduct.DataBind();
as it requires a datatable i converted the list to a datatable when i run it it says null, im not sure where im going wrong, i noe the list works as i tried populating on a table.
public static DataTable ToDataTable<T>(List<T> items) { }
I have an HTML5 form with a number of text boxes on it. I would like these textboxes populating with data retreived from an SQL database, using inline C#. I have a stored procedure that returns the data.
i found somewhere online this code that populate my listbox with file names. Now is it anyhow possible to filter those names before it gets populated by regex ?
i m working on a simple project, i want to populate my text boxes and comboBoxes through DataGridView, means when i double click on cell content then the text boxes are populated.my question is that if i have to populate comboBox with the specific value then what i have to do then because comboBox.selectedItem is an object but my class property is a string..
e.g combobox shows 30 days in it and my class is Code: class account { public string day{set;get}
[Code]....
but that does not happen because "comboBox.selectedItem" is an object so if i have to do that what i have to do then?
I have a window in WPF which I want the user to use to enter the information for a COM Port.
The intent is to populate two ComboBoxs from a two different ObservableCollection<string> which I am having no luck with.
I don't think that it is a DataContext issue, as I am able to get something from the ComRateList when the window opens, but nothing from BaudRateList. Either way I have included the way that the window is opened and DataContexts assigned...
When the code runs, the COM Port list is updated when the window opens - However, it is not updated when the user reclicks the ComboBox which was my intended behavour.
All the adds for the BaudRateList do not populate the ComboBox for the baud rates on start up, nor when the code is running.
When I step through the code, I can see all of the BaudRateList items being added... The window is called by the main window's datasource like so...
OpenSerialCommunication OpenView = new OpenSerialCommunication(); OpenView.Show();
This opens fine.
The OpenSerialCommunication.xaml is as follows: (Note that any business names have been replaced with [snip])
<Window x:Class="[snip].SerialCommunication.OpenSerialCommunication" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:serial="clr-namespace:[snip].SerialCommunication" Title="Open COM Port - [snip]" Height="300" Width="300"> <Grid>
I would like to fill a combobox with particular field for example if i have atable with fields such as CustID, CustName, CustAge.
I would like to only fill the combobox with the Name filed such that only the CustNames will be field in the combobox and am able to write an event handler for the selected index.

I'm working on a CGI application. I'm trying to test my input with a switch statement and output the result with html tags to populate a web page. From within the switch, I've coded as follows:
HTML Code: switch(mFunc) { case 0: cout << "<p><b>YOU ENTERED THE FOLLOWING TO BE CALCULATED:</b></p>" "<h2>"<< number1 <<"+" << number2 << "</h2>" << endl; break; case 1: cout << "You've entered" << number1 <<"-" << number2 << "to be evaluated" << endl; break;
I know that I'll need to put this in an html body with a content type as such:
I am interested in creating a file of a given size and then randomly accessing the file to populate it. Is there a way to quickly create, for instance, a 4 GByte file in C++, initially populated with garbage?
private List<Vector2> myVectors = new List<Vector2>(); private List[] myListOfListsOfVectors = new List[10]; for (int i = 0; i < 10; i++){ myListOfListsOfVectors.Add(myVectors); }
Or better yet, if I can create 10 lists called "myVectors" and access their objects by "myVectors[1][objectIndex];"
I am trying to create an dynamic array (lno) This array will store addressess of different Linked list. What exactly I want is:- Take N Number of Linked List user want to create> eg. 2 now It will create 2 linked list for which I am trying to allocate memory.
Code:
struct node{ int data; struct node *next; }
first; lno[0] Node 0's first address stored in ln[0] lno[1] Node 1's first address stored in ln[1] Here is the code in which I am facing problem with error Illegal structure Operation
Each processor is going to delete some of the assigned numbers.Is there a 'standard' technique for merging the arrayparts at the end of the parallel section (in pthreads)? If there are a neater way of doing this with lists Im also interested in that.
Example: After parallel section array is 1,3,6,etc
