I have put in a TRY, CATCH to catch the error and display a msgbox with the error. Is this message in the IMMEDIATE WINDOW just a warning message (generated by access), or is there something wrong with my actual program? My program does not actually crash, it seems to be working great.

.net - Storing Subcollections (filtered Versions Of The Main Collection) Inside The Collection As Cache?
Jan 15, 2010Is 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?

Collection Index Must Be In The Range 1 To The Size Of The Collection?
Dec 17, 2009I'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.

C# - VB Collection - Convert To A Modern Collection?
Jun 26, 2012I need to convert a VB Collection to a modern one, like Dictionary or Hashtable. For my approach, I need the Collection's KEYS. Googling tells me that it's impossible. Re-writing the entire application using new collections is not an option as the application is really old and large (converted from VB6 to VB.Net).Using the old Collection also is not good - as there are new components in development.Converting a - for example - Hashtable to Collection works:
using VBCollection = Microsoft.VisualBasic.Collection;

VS 2008 Does FIND Always Find Within The FILTER Of A Binding Source
Jun 8, 2009I've got a form - CMCConsole It pops up a dialog form for adding a new case.If the matter number in a textbox on that dialog form matches an existing cases matter number I would like to find it in the binding source of the CMCConsole form
Private Function CheckMatter(ByVal MtrNum As String) As Boolean
Dim cfIndex As Integer = CMCConsole.caseBS.Find("MatterNumber", MtrNum)
Dim cfIndex2 As Integer = CMCConsole.casefileBS.Find("MatterNumber", MtrNum)

But it appear the filter for the CASE we were just on that is set on the binding source is keeping the FIND from seeing other cases.
caseBS.Filter = "CaseId=" & e.Node.Tag.ToString
Do I have to clear the filter in order to find a matter number in some other case??

View 1 RepliesFind Function Does Not Find Last Occurrence
Dec 12, 2009I have a rich text box with the following text in it:
word word
I am finding the endings of the word, that is, the string "rd". The following code finds the first occurance, but then fails to find the last occurance, and the variable "indexToText " changes to -1.After the first search, the debugger shows the startLocation at character position 4, so it is not past the second occurance but still will not find it.
indexToText = FrmMain.RichTextBoxPrintCtrl1.Find(searchValue, _
startLocation, eof, RichTextBoxFinds.None)
If I change the text to:
word word word
It then finds the first two occurrences and fails to find the last occurrence.No matter how many words I add, it always fails to find the last occurrence.
