I'm trying to use the bindingsource.find method to match a datarow column with a user entered text. I know that using BindingSource1.find("columnName", searchString) will work when the user enters the exact string. What I would like to know is how to find a row that is close to the string using a wildcard search... a good example I guess is:dim searchString as string = textbox1.text 'lets say the user enter "se"dim index as integer = myBindingSource.find("columnName", searchString) 'I would like to find the firs record that starts with "se"I can achieve the idea using the bindingsource.filter method but this will interfere with other parts of my application if the bindingsource is changed.

In my application, I have a single table. Two of the fields in the table are COUNTY and CATNUM. Both are string.
I want to perform a FIND on both fields. I have no problem doing the search on CATNUM alone IF I set a FILTER first. Due to the size of the table, it takes a few seconds to set the filter. Once the filter is set, .FIND works quickly.
The customer has the option of setting a filter to work on one COUNTRY at a time. If they choose to do so, no problem.
If they don't have a filter set and they are using the entire table, then when the customer wants to search for a COUNTRY & CATNUM, I present a list of COUNTRIES in the table and a textbox for them to input the CATNUM.
Now I have the COUNRTY and CATNUM - how do I do the FIND? I already know that I can FILTER the table by COUNTRY then do the find but as I said before, it takes too long for the filter to be set (in my mind anyway!).

I have a bindingsource that is connected to a table where tho fields determine uniqueness. During a refresh I would like to return to the row that the user was on when he clicked the refresh button. BindingSource.find only supports one column in so far as i have been able to infer. So how doi do it. Altering the table is out of the question. Besides searching on multiple fields is a common event. Like for example first and lastname or perhaps company and journal number.

So I got this DB and I have these values
Hash | Value
abcd | "test"
efgh | "test2"
I want to search my db for the value abcd, so I wrote this Private Sub Button1_Click_2(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click MessageBox.Show(Me.Table_0BindingSource.Find("Hash", "abcd"))
End Sub
but I keep getting -1 even if there is no data that matches what I want to search.
How can I do a search using Data Sources?

I've got a databound query in my application which is querying the "Customers" table in our database.I've created this directly from the ComboBox's datasource creator in the Design view.Various bits of code created in the designer include:
Me.CustomerBindingSource.DataSource = Me.CustomerDataSet
Me.ComboBox_Customers.DataSource = Me.CustomerBindingSource
What I've done in the first stage of developing this feature is to show my users a ComboBox showing a specific subset of the customer list by applying a filter to the BindingSource.
Me.CustomerBindingSource.Filter = "someColumn = 3"
What I want to do on a second pass is to allow the users to type a specific bit of information into a textbox and check whether it appears in Me.CustomerDataSet like so:
Dim x As IEnumerable(Of CustomerDataSet.customerRow) = From cust In Me.CustomerDataSet.customer Where cust.custno.Trim = "test"
If x.Count <> 0 Then
At this point, I have a customerRow object. I want to check whether this customerRow object appears in the list presented to users in Me.ComboBox_Customers via the filtered Me.CustomerBindingSource. Me.CustomerBindingSource does not (directly) contain customerRow objects, it contains Object objects.How do I find out whether Me.CustomerBindingSource contains the customerRow object at whatever lower level?Also Once I've determined that Me.CustomerBindingSource contains the item, how do I select that entry in the ComboBox?

I'm binding a DataGridView to a BindingSource to a LINQ IEnumerable, I found that the BindingSource.Find method throws an exception because .Find isn't implemented in IEnumerable (and the BindingSource just passes the call to it's DataSource). I need to use BindingSource.Find to select/highlight a particular row in the DataGridView.
Is there a feasable way to extend my DataContext to support this behavior w/o breaking anything else? I expected to find the code out there already, but I've searched exaustively with no luck.Without it, I cannot "move" the BindingSource using .Position and that's a pretty common use of the BindingSource I think.

There a dictionary object that gets loaded with the following key values:
[Code]...
In most situations, life is good and all the individual key values are needed/unique. But in certain situations, the keys with letters behind them (ie...189a, 189b, 189c) all mean the same thing (ie...189). So I need a way to see if a key value exists (like the containskey method) for only the first part of the key and then return true.

I am having trouble uploading any file to the path in the error message below. Does anyone have any idea what the problem is. I did some research on this and most sites say that the permissions need Read/Write access for the asp.net user. I tried this and I still receiver the error. Here is the error:
For example Error saving file education_calendar.pdf System.IO.DirectoryNotFoundException: Could not find a part of the path "d:inetpubaophaUploads". at System.IO.__Error.Here is my code for the click event. I am not sure what is happening here:

The pattern should have succesfull match if the source string is either DAY1 or DAY2 or DAY3 to DAY31 like so.

I have an xml file I parse to get a path to some other xml files that I then want to parse and read values from. I am fine to get the path from the first xml document and fine to parse the subsequent documents.Where I am struggling is implementing the path. It is being stored using system level variables like:
%appdata%my_appconfig
When I try open the file like this:
xmlConfig.Load(userConfigFile)
It tries to start in the application working directory - assume c:emp So the error message I get is:
Could not find a part of the path 'C:emp\%appdata%my_appconfighive.machine.xml'.
Is there a way I can use this pathing structure in my VB code or determine the actual fully qualified path programatically?
