Can't Find Table Even Though It Exists
May 10, 2009I'm using the following code (System.Data.SQLite within VB.net)[code]...
I know the table exists because I can write to it via the command line through sqlite and through Autoit and can see it and edit it in the SQLite browser when I open the database. I don't understand why VB can't see it (I know it sees and opens the database file just fine).

View 4 RepliesFind Exact Match Of A Word In A Textbox If It Exists
Nov 20, 2011I need a way to tell me if a certain word already exists in a multi-lined textbox. Right now I have a multi-lined textbox with some names inside it. After each name I add a newline so all the names are on their own line inside the textbox.I use this code to add names to the textbox, Text Box1. AppendText(ComboBox1.Text + vbCrLf)Then I have been checking if the name exists by doing it this way,[code]The problem is that Ted and Teddy return the same when searching for Ted even if Ted isnt in the textbox at all, I have googled for the last few days and even tried RegularExpressions and still the same results. I think this might be a simple true or false check but I may be wrong... or even a loop or something line by line.

View 5 RepliesWhy Does File.Exists Fail To Find 6 / 115 Files In Directory / When Same Process Just Downloaded All
Sep 5, 2011I have a process serves as an application updater.It checks it's local cache of files and compares this against list of files online.On it's first run there are no files in the local cache and it therefore downloads ~100 of these files.[code]This appears to work very well, since Explorer confirms that all files are extracted and available.However when I later run this process again, it cannot verify the existence of 6 of these files and therefore tries to download them despite the fact that they are clearly both present and up to date.The offending code is a simple File.Exists call which appears to deny the local existence of these files, and therefore tries to get them again.The system continues to work well, but over time the continual downloading of these 6 files is going to get kind of silly.

Find The First Record On Form From A Combobox In Visual Basic 2010
Jul 14, 2010This is well documented and easy to accomplish in Access, but how does one accomplish this in Visual Basic 2010 on a form designed in Visual Studio that is bound to a SQL Server database?
The idea is to create a combobox that holds 2 columns - a primary key value and a unique value such as a [Company Name] or a [Student Name]. The user would then find the appropriate record within the combobox and the code behind the combobox control would then perform a .findfirst method that would NOT filter out all other records, but would rather use selectedvalue primary key column value to move to the selected record.
I am currently getting into VS 2010 & revisiting VB having been programing in ACCESS & VBA for years. In the Access/VBA environment it is very common to have to find a given record on a given form using this method, but it would appear to be poorly documented if in fact not commonly used in the VB.NET/VS community.

VS 2008 - Item Exists In Listview?
Sep 9, 2009I am filling a listview control with a big number of items but i came across an problem, the repeated values. In those items i use .Text and .Tag so i can relate some hidden values per item. I have been trying to use the items.find() with no luck since it looks like to search for keys, which i don't really have. Every item has different .Tag values but it can happens that they have the same .Text Is there any way to remove or just not add items based on a .Text search in the ListView?

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)
[code]....
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??
