Collection Of Locations - How To Skip First Record
Apr 7, 2009
I have a collection of locations for a sales person, allowing them to send an item to multiple locations. I want to start reading at index 1 since I am using a collection. I saw an example where you can say something like "+ 1" (e.g. myitem.SelectedIndex + 1) to skip the first record. How can I skip the first record for the following:
Public ReadOnly Property Customer() As ICustomer
Get
Return CType(Me.CustomerList.Item(Me.CustomerNumSelected), ICustomer)
End Get
End Property
I tried to say Return CType(Me.CustomerList.Item(Me.CustomerNumSelected + 1), ICustomer) but it returns an error saying "string cannot be converted to a double". without the + 1 in there, I get an error that says "collection index must be in range 1 to size of collection".

I am looping through several hundred records from a XML file and inserting in SQL server 2008 using LinQ from my Web Service.My question is, for some reason if a record is not inserted it is coming out of the loop and going to the Catch block directly.

I'm just getting started with collections (ObservableCollections). I have a WPF screen with a DataGrid to the left and TextBoxes to the right of the screen. The DataGrid is bound to the ObservableCollection (Activities) and I can click up and down the DataGrid and see my TextBoxes refresh with the correct info. I can then alter the info in the TextBoxes and save it back to the DB. All works perfectly!
However, when it comes to Adding a record to the collection I'm lost as to the correct approach. I'm using the Add method as shown below, but how do I move to this newly created record so it can be edited? I've tried a dozen approaches but I've yet to find a correct approach. The TextBoxes just remain focussed on the last edited record.
Private Activities As ObservableCollection(Of ActivityRecord)
Private Sub AddMode()
Dim _ActivityRecord As New ActivityRecord(0, DateTime.Now, Nothing, "", gWorkerID, "")
Activities.Add(_ActivityRecord)
'Code to move to the newly created record should go here

I have run into this problem a number of times, and I am not sure what I might be doing wrong - or if this is just a bug, or not going to work.I have a collection that I setup on my own (eg, collection class). I then cycle a Log file that has text entires and I read those, and then parse the entry and attempt to add it to my collection.
But as each entry is added, ALL records just get duplicated - in other words, as I add entry 2, both entrys 1 AND 2 wind up with the same values - as I add 3, all 3 entries get the same value - and this continues no matter how many entries. For example,
if I added 100 entries, I would have 100 duplicates of the last record added.I have stepped through the debugger and watched this occur and just cannot figure out why this is not working as it should. Here is the code...
While
Not objReader.EndOfStream
' Read one full line
[code]....
No matter what I do, my lstSent collection just winds up with EVERY entry being the same as the last entry added.
End
IfFalse'
Add the elements into the collection if its a "Sent" itemElem = objReader.ReadLine

Is it good practice to store sub-collections of item X inside a parent collection of item X for caching 'filter-queries' which are performed on the parent collection? (They won't be used together (as in color AND type).) Or is it also ok to just Loop over the collection and return the correct entities in a temporary collection?

After a path is defined with all its components, is there a version of the DrawPath that allows the composite object to be drawn in locations other than the initial locationsFor example, the code shown below displays an ellipse and two rectangles in a specificocation. To also display the same objects in one or more other location,s, is it possible to disply the defined path at other locations or is it necessary

I am working on making a picturebox that when clicked in a general location it will do something. Is there a way to make a grid out of a picture so when a certain slot on that grid is clicked an event will happen? It cant be an exact location, because that will be too hard to click. but a relative location would be perfect.

The file locations for a setup package using Standard Edition? I have added an .xls file to my project, marked it as Content and as Copy Always in the properties for that file. The XLS file I added to the project is from my user Apps folder in the Roaming sub folder. Other simple .TXT files are in my UserMy DocumentsData folder and each file is also maked as Content and Copy Always. When I create the setup package all goes well. I have a setup.exe and an .msi file. When I test it by installing it on my PC of course the program knows where the files are because it's my PC. In the program folder created as C:Program FilesMyProgram I find the .exe plus the XLS and TXT files, but these XLS and TXT files are not used from the program folder. How might I know if an installation made by another user on another PC elsewhere is going to load files in their user apps or user documents? I need to be sure that the additional data files deploy to the correct location (whatever I want that to be) on a remote PC.

I've got the following ADO.NET Entity Framework Entity Data Model:I want to find all the Policyholders with both a Service of a given Id and also a Keyword of a given Status.
This LINQ Does Not Work:
Dim ServicesId As Integer = ...
Dim KeywordStatus As Integer = ...
Dim FoundPolicyholders = From p As Policyholder In db.PolicyholderSet.Include("Keywords").Include("Services") _
Where p.Services.Id = ServicesId _
And p.Keywords.Status = KeywordStatus _
Select p
The Where clause cannot search the p.Services and p.Keywords EntityCollections in that way.

I've been working with a CMS called InsiteCreations 2008. I'm running into an error I just can't wrap my head around. I would even be willing to compensate anyone a small amount over paypal, for a solution. The error is rare in occurance, and appears when clicking about 3-4% of links to other pages within our CMS.The full code page is quite large, but there seems to be only one function associated with the error. The error also only appears when not logged into the CMS. If logged into the CMS, clicking the link simply displays the page as normal. I have already checked permissions on the page from the CMS admin console, and it is public.
The error message is as follows:
Server Error in '/' Application.Collection index must be in the range 1 to the size of the collection.
Description:
An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I'm working on a little board game we play here in Jamaica just to see how it would look and as a sort of challenge for myself while on vacation. I'm however stuck on how to make my markers (PictureBoxes - two per player) move along the board.So heres my problem; I have 40 slots where the picturebox can be moved to (eg picturebox1.Top = 324, picturebox1.left=243). Now moving to these slots are determined by the roll of a pair of dice. How can I assign a variable preferably an integer for each slot so when the dice is rolled I can just do a little addition as to where the markers can be moved?

I am trying to create an install for my application that I have just created using visual basic express. I want to be able to tell it to put files in certain locations and create my own installer. For example I want to make a license page with a read me on the installer. From what I understand the clickonce technology is what comes with express editions and you cannot do it with them. Is there an alternative to being able to accomplish what I want to do without having to purchase the full version of visual studio?

Greetings,
My app saves a bunch of stuff to an XML file. This is my line of code-
Using writer As XmlWriter = XmlWriter.Create("C:vdx2kMWSREEXTReportsInboxTK" & frmCitation.txtCiteNumber.Text & "Traff.xml", settings)
So that saves it at that specific location.
I need to duplicate the XML and have it also save in another location. I've been at this for days, Googling, searching, trying different things and now I need to turn here for help.
Any ideas?

I want to show some forms but I want them to appear on specific locations . The problem is I don't know how to specify the coordinates . Using :
frm.Location = "0,0"
or
frm.Location = (0,0)
tell what is the correct syntax ?
And more thing : when a form is maximized or minimized , it looks like "flying" upwards or downwards . Is it possible to stop that visual efect ?
