Bindingsource Find Using A Wildcard?
Feb 5, 2009
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 want to search particular item in Binding Source for which i use BindingSource.Find() method, but it throws an exception "This operation requires an IBindingList". My binding source is bind to a .net class object.. I searched over the internet, but could not find the clear solution to achieve this task. The sample class code is given below:

What I want to do is to replace lets say ##test## with Something(test)..I know that I can find ##test## by: (Though don't know whether there's a smarter way)
System.Text.RegularExpressions.Regex.Replace(str, "##Test.*##", "Output")
So basically the problem is to get what the wildcard (.*) is, since thats really what I need to know..

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.

I've been having problems extracting the value of a Regex in a String. I have a string with several regex expressions and I need to get the value of each expression's match. The thing is though, it's not returning the last match correctly. For example:
Regex Pattern: I play (S+.*?) and (S+.*?)
String: I play the guitar and the bass The program is returning the value of the first expression as "the guitar" but it's returning the value of the second expression as "the" instead of "the bass".

How can I use wildcard/s for the attachment filename. Part of the filename changes but the characters 8 and 9 (counting from the left to right) always present and always either LK or KL. Currently files are PDF type, thus with extension PDF but might be different in the future (this is not important now).
Here it is: Dim oAttch As Net.Mail.Attachment = New Net.Mail.Attachment("C: est102309LKO.pdf")

As you can see in the picture I send my wildcard parameters to my query if the "textbox" does'nt have any content. But when the query require INT, and not STRING, I don't really know what to do.Is there another kind of wildcard when it's INT?

searching a directory for a file, and if it doesn't find that file to search again for a similar file and notify the user that a image does exist but for a different revision.
Sub GVC_Photo()
Dim photostr As String = "R:itemphotosp_"
Dim photostr2 As String = "R:itemphotosp_"
Dim photostr3 As String = "R:itemphotosp_"
Dim photostr4 As String = "R:itemphotosp_"
[code]....
This code snippet is used in a program called SyteLine, so some of it may be unfamiliar, but its .net based. The item and revision are fed through from the form, so when the string gets built it might look something like this "R:itemphotosp_22554_B_01.jpg" with "22554" being the item, "B" being the revision, and "01" being the image number. So what I want is if it cannot find a file name with revision B in it, to search for a filename with any revision it it "R:itemphotosp_22554_*_01.jpg", if it finds one to display a message that a non-current photo exists, and if it can't find that, to display a message saying there is no photo.

I'm trying to query a Datable. I can do this just fine: [code] gives me an error: "Error in Like operator: the string pattern 'a*e' is invalid.". Why can't I have the wildcard in the middle? I want to find values that start with something specific & end with something specific & I dont care what's in between.

New user here. I've been searching high and low for what I would think is a relatively simple task. I want to rename a file with a wildcard (i.e. FileNamexxx.xls) within a Visual Basic Script. I'll be running this script within Visual Studio.
I will only have 1 file in this folder, so I do not believe a loop is necessary.
Actual FileName is "CellModelHistory1251234.xls"

I'm importing a .csv file into my SQL Server (2005) using SSIS on a schedule, after its imported I would like to change the name of the file. The name of the imported file is always different as its coming from an external source.Is there anyway of changing the table name?
I've looked at using the stored procedure sp_rename, i.e.
Code:
USE TESTDATABASE1
GO
EXEC sp_rename 'dbo.SalesTerr5673A1889', 'Values';
GO
What I would like to use is a wildcard?

I want a string search/compare with wildcard. I'm trying to create a "crypto crossword" application and got most of the code working but the wildcard thing was harder than I thought.
Basically I want the program to compare if "H**LO" is equal to "HELLO" (true). But "HE*" is NOT equal to "HELLO". I tried with regex but the number of wildcard is different each time and in different places so I never managed to make it work.

I am working on an application in vb.net to move files back and forth between a client and a ftp server. We will be creating, deleting, and renaming temporary files during our update process.I want to check for the existence of a temp file before I begin an upload process to keep different users from trying to update the same file at the same time. I have a method (below) to check if the FTP file exists (using ContentLength), but I want to be able to pass in a string with a wildcard such as:
FileServer.FtpFileExists("MyTestFile.*.txt") Can I use a wild card with a FtpWebRequest object? What about a regular expression? Or should I pull down the directory(between 200-500 files) and iterate through that list on the client side trying to match with a regex/widcard?

I am having difficulty with searching on a Dataridview. I want the user to be able to enter a characters into a textbox and as they enter them the Datagridview will reduce down base on the name that is being typed in.So for example the user types: Smthis will show all the Smith and all the Smarts etc.So to do this user the Textbox change event. This I think works ok. The problem I have is getting it to filter on that data.

I have a method that takes 2 string arguments. One that contains a normal string and one that contains a string with one or more wildcard characters. I've tried the following code:
Private Function DoesMatchWildcardString(ByVal fullString As String, ByVal wildcardString As String) As Boolean
Dim stringParts() As String
Dim matches As Boolean = True
[code]....
The I realized that it won't work properly. If I have ABCD as a normal and A*CD as my wildcard string the match will work even if my normal string was CDAB, which is not what I want.
