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?
Employee 1/7-1/13 1/14-1/20 1/21-1/27 1/28-2/3 and so on... A sum of values for this 7 days B C D
I want to add all the values of Job1 for each employee in a time range which is one week starting from monday to sunday. How can I group the Job1 values week wise and store them in another datatable.
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.
I would like to return multiple values from one function to access in different functions. For example:
int function1(//what goes here?) { int a ; a = 1 + 2 ; int b ; b = 3 + 4 ;
return (what goes here if i want to return the value of a and/or b to use in another function?) ;
void function2() { //now i want to use the value of a here to use in an equation, how do i do that? //now i want to use the value of b here to use in an equation, how do i do that? }
I am working on a text based RPG. As with most RPGs the character has attributes that grant modifiers. Lets take strength for instance. Suppose the character can have a strength score that ranges from 1 to 10. Based on strength the modifiers could be like the following:
Strength = 1 grants +1 to hit and +1 damage Strength = 2 grants +1 to hit and +2 damage Strength = 3 grants +2 to hit and +3 damage
I want to set these values at design time and be able to retrieve the modifiers based on the strength value from multiple places in my program.
What is the best method of designing this. I looked around online and saw references to Lists with Tuples and Dictionaries with Tuples but these did not seem to be a very efficient way of handling the scenario above.
I want some simple code which will return only the DriveInfo from one drive. I have the below code but it isn't displaying what I expect it to display, I have a feeling i'm using Linq wrong!
var dname = from n in System.IO.DriveInfo.GetDrives() where n.Name == "F" select n.VolumeLabel; richTextBox2.AppendText(dname.ToString() + " ");
The above should return the devices VolumeLabel which is in port F.
I am trying to query fields in a where clause using LINQ to SQL and for some reason I cannot figure out why it doesn't work:
var qryGetMonsterID = (from students in dbContext.tblStudentPersonals where (students.givenname.Equals(fn)) && (students.familyname.Equals(ln)) && (students.middlename.Equals(mn)) && (students.email.Equals(e)) select students);
The returned SQL Syntax is:
SELECT [t0].[monsterid], [t0].[givenname], [t0].[middlename], [t0].[familyname], [t0].[homeaddress], [t0].[city], [t0].[state], [t0].[postal], [t0].[primaryphone], [t0].[secondaryphone], [t0].[email], [t0].[username], [t0].[lastmodified], [t0].[modifiedby] FROM [dbo].[tblStudentPersonal] AS [t0] WHERE ([t0].[givenname] = @p0) AND ([t0].[familyname] = @p1) AND ([t0].[middlename] = @p2) AND ([t0].[email] = @p3)
Not sure but the values for middle name could be null - because not everyone has a middle name and the same is true for e-mail.
I used to use map to access elements. map has a good feature that it sort the element automatically. Now I need a map which can access element through multiple key values. So I choosed boost::multi_index_container. I defined a container as follows.
struct elem { int a,b; elem(int aa,int bb):a(aa),b(bb) {} };
typedef multi_index_container <
[Code] ....
What I am wondering is whether boost::multi_index_container can sort elements automatically. Specifically, are all elements extracted through iterator from begin to end shown below having b values between 2 and 100?
test t; test::iterator begin = t.lower_bound(make_tuple(1,2)); test::iterator end = t.upper_bound(make_tuple(1,100));
I basically need to take line1, line2, and line3 and return them to the reverseString function. Also, I am not allowed to do anything like make my own classes. I have to stick to the basics and no higher level programming techniques since we have not learned them yet.
So I have to write a code for my C++ class, and I am having a problem trying to figure out how to get my code to read multiple int values. This is what my code should look like
Enter two times in military format (e.g., 1730 1520): 1730 1520 [1520<1730] Enter two times in military format (e.g., 1730 1520): 1520 1730 [1520<1730] Enter two times in military format (e.g., 1730 1520): 1730 1730 [1730==1730] Enter two times in military format (e.g., 1730 1520): 1760 1520 1760: [INVALID TIME 1] Enter two times in military format (e.g., 1730 1520): twelve 2 [INVALID NUMERIC INPUT]
It seem to store the entire line in userID including the ":". I want to ignore the ":"'s and store everything in between in respective varibles in the order specified above.
So first string in userID, then ignore the :, then second string in name, and ignore the next :, and so forth.
How difficult would it be to program a hash-map system where each "key" can have multiple values under indexes?
For example: "Word" -> 45(index 0) , 67(index 1) , 12(index 2). What could I start with to program this or where could I find a pre-made system that does this?

I am trying to query dates between two textbox values converted to datetime in C#. The dates are returning in the correct datetime and no conversion problem exists there.
However when I run the below LINQ to SQL query in C# it returns no enumerable results. But if I take the below code:
DbCommand dc = dbHistoryContext.GetCommand(qryRes); Console.WriteLine(dc.CommandText);
and get the results as a string of text and cut and paste that into the SQL Server Management studio and execute it - then it works. What do I need to do to search between two dates so that it properly works. The field is of format Date in SQL Server if that matters and the fields being used to pass the information to it are DateTime. The compiler doesn't show any errors but it just doesn't return results.
var qryRes = (from res in dbHistoryContext.tblR where res.updateddate >= dtDateFrom.Date && res.updateddate <= dtDateTo.Date select res);
I've been struggling with an object when trying to add it to a list with [Listname].push_back. You see, I have a list with some objects that will be rendered in the screen (Called objects) and a function to create a text box with some text. The function in question is the following:
(txtNum is increased then space is pressed, and when certain screen (maxScreen) have been shown, then it will go to the playing state)
My problem begins when the text box is created, because it's supposed to add only 1 text box to objects list, but instead adds hundreds of text boxes to objects.
Have tried to track down the delay? Which function takes that long? Have you printed some logs or measured the time of the functions? No I am not sure how to do that! I debugged it but i didn't see any difference! I definitely think its the logic in the receive code that's "inefficient" what do you think about that? Do you think there's a more efficient way of receiving messages and sending them? Because what I am doing is receiving one then calling send and sending that message out to all users then receiving another one then calling send and sending it out to all users and repeating that process till all the messages are sent, both methods are using a loop to send to all users. DO you think i should receive all messages then send them all out at once? or is that less efficient?
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.
i am trying to find the max value from a list of 10 values. here i have stored the double values for prices of items in numVal.There are 10 values in numVal i would like to find the max and min value of these numbers. getPrice(1) returns the ten double values.
for(int i = 0; i < store.size(); i++) { double numVal = this->store[i].getPrice(1); }
I have a list of integers that i wish to store in some kind of array. However i do not know how many integers are needed to be stored each time i run my program so i therefore cannot define a size for my array.
