How can I apply/combine both of these so that it will figure the datediff for each row (on a datagridview), figure the appropiate case and then update each annual leave row in the database?
[code]If I wanted to get Part Name for multiple PartIDs from OrderDetails, how would I go about doing this? Would I use two DataTables? I'm confused as I cannot see an efficient way to do this. The only thing that I can think of is to create a DataTable with SQL:[code]and then maybe use a For loop to take each PartID, create another DataTable to find the PartName for that and then give this to a variable. There could be up to 10 PartIDs to search through and I don't want to have variables such as PartID1 PartID2 etc. [code]

I have one text box that contains a value for the "Start Time" and another text box that contains a value for the "End Time."Both of the values are expressed in a format for military time (i.e. 1200, 1300, 1430, etc.).When the "End Time" text box loses focus, I would like the "Elasped Time" (expressed in minutes) to appear in a third text box.Seems easy enough...right?Well the problem I'm having is since the first two numbers in military time are base 24 and the last two numbers are base 60, a standard calculation subtracting the "End Time" from the "Start Time" does not yield an accurate result.
View 3 RepliesI have a monthly forecast showing expense accounts by cost centre so columns headings look like:
Cost Centre, Account Number, Jan, Feb, Mar etc
Using VBA code to automate the process, I need to calculate the total for each month of each account number where the 2 left characters of the cost centre are the same. I have a formula which will calculate this (for one cost centre grouping/account) which looks like this:
=SUMPRODUCT((LEFT('Sheet2'!A6:A5136,2)="BE")*('Sheet2'!C6:C5136=AccountNumber)*('Sheet2'!D6:D5136))
I am not sure whether there is a more efficient way than using a formula like that (at the moment this would be used for 12 months on about 6 cost centre groupings with about 500 accounts each - though this would vary). Its not massive, but could be slow to calculate. I don't think the subtotals command is powerful enough, and I haven't used arrays for a long time (especially for what would appear to need a dynamic, mulch-dimensional array).

I am coding a lottery number generator for a homework assignment. My project needs to have functions that return random values based on a range given. The first function I am coding is for a pick 3 lottery game.The function should return three random numbers between 1 and 9. I have coded the function but it only returns one number. When the debugger runs it says my function does not return a value on all codepaths.

is it possible to sum all the Value based on type, and then based on month?

For clarification, I have something like this:

I'm trying to add some extra key/value pairs to a combo box using VB.NET. The initial item list is generated from a hashtable, which contains a collection of objects.I've managed to add the extra values to the box using the Add method, however I now run into problems when reading back the selected item from the combo box because some list items are objects, while others are strings.
My best option seems to be to load the initial data as key/value pairs by looping through the hashtable, however this doesn't seem to be working too well either because I'm still getting errors.I'm getting frustrated because it's taking me hours to do something that should take 5 minutes!

View 3 RepliesI have a query I'm using to identify a group of contracts that have expired. The query has a ContractID, Status, Start Date and End Date. For each contract, I need to go to a directory and search for a file to import. That part works just fine, but how can I put a qualifier in to check for contracts that have the same start and end date? Do I need to create a multi-dimensional array for this or can I use the query I have? The part in bold text is where I need to identify identical start/end dates.

Im working with a DataGridView with an imported CSV file where the values are delimited with (,).. The grid works perfectly fine. My ultimate goal is to hide the grid out of view from the user and access the data in the grid based on the coordinates of the grid specified i.e (The cell in column 5, row 6 contains the value "Taco") and I want to save that value to a variable...Eventually I want to loop through all the values of a column and save them to individual variables to be later used. So far, this is what I have...
Dim sReader As New StreamReader("book1.csv")
Dim Record() As String
For x As Integer = 0 To 17[code]....
Presently, that will only display the data in column 0, row 0 in those labels...
Note: 17 in the for loop is the amount of columns in the data i provided.. that number will never change.

View 3 RepliesI have a set of classes that mimics enums (see my other questions for specific details/examples). For 90% of my project, I can compile everything in at design time. But the remaining 10% is going to need to be editable w/o re-compiling the project in VS 2010. This remaining 10% will be based on a templated version of my Enums class, but will generate code at runtime, based upon data values sourced in from external configuration files.what my Enums class looks like. The templated fields, per that question, will be the MaxEnums Int32, Names String() array, and Values array, plus each shared implementation of the Enums sub-class (which themselves, represent the Enums that I use elsewhere in my code).I'd like to parse values from a simple text file (INI-style) of key/value pairs:
[Section1]
Enum1=enum_one
Enum2=enum_two
Enum3=enum_three
So that the following code would be generated (and compiled) at runtime (comments/supporting code stripped to reduce question size):
Friend Shared ReadOnly MaxEnums As Int32 = 3
Private Shared ReadOnly _Names As String() = New String() _
{"enum_one", "enum_two", "enum_three"}

I'm certain this would need to be generated in MSIL code, and I know from reading that the two components to look at are CodeDom and Reflection.Emit, but I was wondering if anyone had working examples (or pointers to working examples) versus really long articles.

I am trying to limit this list to rows which have unique Dates and unique quantities in LINQ. I want to remove items with the HIGHER priority leaving rows with unique dates and qty's.
I have tried several group by's using Max and order by's but have not been able to get a result.
Is there any way to do this via linq?
EDIT:
Managed to convert brad-rem's answer into VB.net.
Syntax below if anyone needs it:
returnlist = (From p In returnlist
Order By p.Qty Ascending, p.Priority
Group By AllGrp = p.Date, p.Qty Into g = Group
Select g.First).ToList
I'm looking for a library for Autocomplete support in text controls which remembers all previous entries of the user and provide auto-complete support for it.For example for "recent files" I use [URL] and it works great. Do you know something like that for this purpose?
UPDATE : This is a .NET Winforms application and I'm using normal Text Control.
In this application I need to allow users to enter a month as integer (1-12) then use integer tryparse to validate that input, that seems to be the easy part. I need two create two functions, one that returns the name of the month and the other returns the number of days in that month. The arrays are supposed to be defined and initialized within the function so that the main program can take the user input and call the two functions, then return the appropriate values as output to labels. I am not sure how to declare the arrays in their appropriate functions and then how to call those functions to retrieve the right value from the function.

lets say I have a form (form1) with lables a-z which are all designed with default text "0". So they all show 0 on program startup. which is fine. I also have a dialog with 2 TextBoxes; I want my program to update the default text/value on (only)form1 labels x, y and z to whatever was put into the textboxes when i press the OK button on the Dialog, so these specified labels show the 'new' value on next startup. Is it even possible or should I save the values to a file which loads the values in the specified labels on startup?

Now I need to exclude another value ("Awaiting Progression") from a second column called "PROGRESSION".
Since I already exclude value based on 1 column called CATEGORY, how do I change my =Sum(Code.ExcludeOthers(Fields!CATEGORY.Value,Fields!ACTION_PLAN_NEW.Value)) to exclude a value from the PROGRESSION column if it's = ("Awaiting Progression") ?
i.e. How do I exclude multiple values, depending on values in 2 columns in SSRS 2005?
