I am need to compare 2 items from 2 separate drop down lists. These values are of int type. Say for example 2 drop down lists showing years. Now i need to find out these 2 years selected is greater or nearer to the current year.
I tried converting the values i receive from the drop down lists to int variables. But i am getting error then. I gave it like below.
int tmp = Convert.ToInt32(ddl_1.SelectedItem.Text);
this gives an error like this - Input string was not in correct format.
I need to know how to put an item from a drop down list to a variable of int data type.
I'm trying to find a way to remove an item that has been dynamically added when I change my drop down list selected user. The way this works is I add an edit and delete button dynamically when I select a user. I need to have the existing one be removed when I change users. Here is the code I'm using to build the two buttons. How do I remove them? Do I wipe out the columns and then add the columns again?
i have an xml which is in showing in multilines and the tags are not in single line and are discontinued in next line .I need to this xml to be in correct format and want to display as xml .

stdfrm std=new std(); std.a=txtpwd;
it displays an error that cannot implicitly convert type system.windows.forms.textbox to string
So I query out data from multiple tables and I put it as anonymous type. But since I need to get the remove function going, my datagridview has to get datasource from a bindinglist, not just a list. What could I do from this situation? I already checked: [URL] but intellisense doesn't pick up the .ToBindingList() function for my query.
Okay, so I'm getting an error I've never seen before.. I'm trying to convert a List<string> to a DataTable. Not a List<string[]>, but a regular ol' List<string>. I figured this code would do the trick, but to no avail:
public static DataTable ToDataTable<T>(List<T> items) { DataTable dataTable = new DataTable(typeof(T).Name); //Get all the properties PropertyInfo[] Props = typeof(T).GetProperties(BindingFlags.Public | BindingFlags.Instance); foreach (PropertyInfo prop in Props)
[Code] ....
I keep getting an error on "values[i] = Props[i].GetValue(item, null);", that reads:
"An unhandled exception of type 'System.Reflection.TargetParameterCountException' occurred in mscorlib.dll
I have a problem set where i have to read in numbers from a file as strings, convert from strings to integers, and pass the integers into a linked list, where each integer is a node. This is what I have so far:
Code: # include <stdio.h> # include <stdlib.h> # define MAX_INT_SIZE 10000 typedef struct integer BigInt; struct integer {
I am trying to make a program that will convert a list of binary numbers from a file into decimal and print the decimal to the screen. I have no problem doing the conversion, the problem comes up when our teacher wants the input file in a format as such:
3 10110101 11111111 10101010
The first number is supposed to tell the program how many different 8bit strings it is going to have to convert, and then the following lines are those binary numbers.
I am not very experienced with file inputs, and I know how to open files and read lines in.. The problem is, how to say "ok the first line says 3, so now I have to convert the next 3 lines" . I am assuming it is just a simple loop that I am missing....

I am trying to query an Informix database using a List<T> collection's elements as variables. I can build the list and connect to the database, but I am unsure how to iterate through the list and query the database for each item in the collection.
My list is of type string, and contains Order Numbers. I want to query item information for each order number in the list.
I want to display the content of my database in list view. The table has 5 columns however when I tried this code
string view = "Select * from cust_infor"; SqlCommand cmd = new SqlCommand(view,FL.clsconnection.opencon()); SqlDataReader dr = cmd.ExecuteReader(); listView1.Items.Clear(); while (dr.Read()) { listView1.Items.Add(dr[0].ToString()).SubItems.Add(dr[1].ToString()); }
It limits the display to 2 columns. List view will only show the first 2 columns. The code above won't let me add more indexes or subitems. Only up to 2 columns.
I am grabbing data from three entities and want to grab a field value in each of the entites and place it in an arraylist. What I would like to do is loop through the arraylist for all the values and do something for each value only once. If the value in the array list is repeated, I want to not do anything for it and continue till the end. Basically, I loop through all the values do something for each value and skip over the repeated value if I already did something.
Basically I am creating a game and I need the ai to look for specific buttons. At the moment this is the code I have, and what it does is it makes the ai look for any random button that has't already been clicked.
Code:
private Button look_for_spaces() { Console.WriteLine("Looking for spaces"); Button b = null; foreach (Control c in Controls) { b = c as Button; // performs a cast
[Code] .....
Now what I'm trying to do is make the ai go through 4 searches in steps instead of looking for any button. I want it first to look for buttons 1, 2 and 3, if there's a space in any then it will be clicked but if all of them are already clicked it will look for spaces in buttons 4, 5 and 6 and so on if that makes sense. But i'm not too sure how I would do it.
