I have the following dictionary:
Dim idQueuedJobs As IDictionary(Of Int32, KeyValuePair(Of String, Int32)) = New Dictionary(Of Int32, KeyValuePair(Of String, Int32))
Why duplicate KeyValue pair? This is because the first Int32 is just a normal index, and the String followed by another Int32 contains systemnames and the priority of the qued job in idQueuedJobs
I want to calculate the total number of systemnames in idQueuedJobs, how can i obtain this count by using the groupby method?
Something like this maybe?
numberOfSystems As Int32 = idQueuedJobs.Values.GroupBy(...)
I am trying to calculate the number of years for my calculate age event handler, however i am apparently missing a method or whatnot because im trying to calculate the age , can anyone suggest help on this. I need to subtract years to get my age but when i try the birthdate.Subtract (currentDate) method i get an error about not able to convert from LONG?
So below is what I have.
Private Sub btnCalculateAge_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalculateAge.Click
Dim currentDate As Date
Dim BirthDate As Date
Dim Age As Long

View 1 RepliesI have some reports that I use with the MS ReportViewer and I need to get a count of the physical pages (as opposed to logical page count) to use with a print dialog. I've implemented a workaround so the ReportViewer control displays the correct number of physical pages, but is there a way to get that value from the ReportViewer control? The only publicly accessible property gives the logical page count.

View 3 Repliesdesigning a Windows based computer program that will allow a user to enter some number (n) and a choice of a count up or count down for that many numbers. So for example, the user enters 5 as their number and selects the count down option, the message box displayed would contain the message: "Here are your numbers: 5,4,3,2,1,0"

During the RowDataBound event, retrieve the data from each column and add it to the appropriate sum. I'm not sure if you are developing an ASP.NET application or a Win-forms desktop application so I cannot help you any further at this point. What have you tried so far to solve the problem?
this its a very silly problem i have with CheckBoxList control, i dont know if its just me or what but the whole idea of the control its just great but the implementation its very confusing.
im trying to eval something like this
if CheckBoxList.Items.Item(CheckBoxList.Items.Count-1).Checked=true then.....
or something like
CheckBoxList.CheckedItems.Item(CheckBoxList.Items.Count-1) = Checked then...
the problem its that i dont know how does the checkboxlist works but it just sucks that they had to make it so confuising....
i've handled lots and lots of collection controls and they all work in a similar and simple
I have a fair bit of experience with VB.NET and C# (In this case I chose VB.NET, blame my laziness), but I do most of my professional work using PHP. I have no experience what so ever in using any database with VB.NET let alone MySQL.Just FYI, at the moment I am only trying to Query the database to gather the information required to activate. The Activation wizard and algorithm building (which is finished anyway), and everything else will come soon. I chose the MySQL database because I have experience with it, and it seems the best option for remote usage.The whole idea already works in PHP, I'm just have major issues moving it accross into VB.NET (Using the MySQL Connector.NET);I understand the basics, and all I need to know how to do is Count Rows and gain access to the other information in a row based on provoided information (in PHP, through mysql_ result)
So, here goes nothing, this is the Query code I am using in PHP to complete the job I want to do in VB.NET. [code] As you can see, I basically need to get the PHP code into VB.NET to fit into the 'btnQueryDB.Click' Command in VB.NET. By Equivalent, the Product ID in VB.NET will come from 'txtPID' and similar, Serial Number will come from txtSNUM. Once counted to be 1, the Activation Code and Status will be fed into 2 other text boxes in the form. (acCode, and acStatus).
This is not useful, but:If you like Mayan culture,This code convert an integer in Mayan numericals
It can convert in the "Normal Count" system and in the "Long Count" system.In the Normal Count", every glyph is a power of 20, with the most significant on top and the less significant at the bottom
The "Long Count" system was used in Calendar. In the "Long count", every glyph is a power of 20 except the third glyph from the bottom, which is a multiple of 360. This was done because the years were, at the begining of the Mayan culture, estimated to be 360 days.Since I couldn't find a Mayan font, the function returns a bitmap that contains the drawing of the glyphs that represent the mayan numerical

I use the following columns stored in a SQL table called tb_player:
Date of Birth (Date), Times Played (Integer), Versions (Integer)
to calculate a "playvalue" (integer) in the following formula:
playvalue = (Today - Date of Birth) * Times Played * Versions
I display upto 100 of these records with the associataed playvalue on a webpage at any time.
My question is, what is the most efficient way of calculating this playvalue given it will change only once a day, due to the (today-date of birth) changing? The other values (times played & versions) remain the same.
Is there a better way than calculating this on the fly each time for the 100 records? If so, is it more efficient to do the calculation in a stored proc or in VB.NET/C#?
I have an openfiledialog, I show the dialog and the user selects there file. How could I calculate the MD5 hash of the OFD.filename/file opened? Or calculate the SHA1, what ever is easiest.
