View 2 RepliesI am doing a search to look for a value that corresponds in my datagridview. But the problem is it is being case sensitive. Is there a way to disable that? The code I am using is below.
Supplier_List.DataGridView1.Rows(i).Cells(0).Value.contains(txtSupplier.Text)
Supplier_List.DataGridView1.Rows(i).Selected = True
Is there a way to enforce case sensitivity in VB.Net file-names?
The primary issue that I am trying to solve is the difference in how Windows doesn't care about the case of a file-name, but other tools, like Subversion, do care about the case of a file-name
I am trying to compare the contents of 2 collections in a unit test in .NET using MSTEST. To make things simple, instead of having to .Sort() and then loop through the collection and compare items one at a time, I've found the new and very cool .Intersect Extension method.
It seems to work great by doing:
Assert.AreEqual(expected.Count, actual.Intersect(expected).Count)
However, now that I have a test which needs to be case-sensitive, it breaks. I've tried sending Intersect's second parameter StringComparer.Ordinal,StringComparer.InvariantCulture, and StringComparer.CurrentCulture... no luck..
EDIT: here is the data:
Actual:
(0) "FOO" String
(1) "foo" String
(2) "Foo" String
[Code]....
It seems to be removing a matching duplicate 'foo', and a matching duplicate 'BAZ'. Perhaps there is a better way to assert collections are matching?
_EDIT2: I think Intersect() removes duplicates, which is why this is breaking. I Found the CollectionAssert Class.
see if an object is already in a generic List(Of T) than the way I am currently doing it? The way I do it at the moment is like so:I have a method that I call each time I want to check to see if an object exists in the list (if it already exists I do not want to add it again) and the list to check is passed in to this method along with the item that should be added to it:
[Code]...
So as you can see this function just loops through the list that was passed in and if the DisplayName property of one of the items in the list is the same as the ProgramName argument that was passed in to the method as well then it returns True to indicate that this program is already in the list.I thought about using a Predicate with the List.Find method but cant see how I would get it to work because that predicate method will not have any way of referencing the list (its a method local list, not class level)
I have a case insensitive dictionary in asp.net/vb.net like this:

I need to check if a webpage exists if it does whether a certain string exists anywhere on the page. Preferably I'd like to do this without a webbrowser control, so that images don't have to be downloaded and it doesn't have to be rendered.

I'm having issues with finding something in list, and removing the item, ignoring the case of characters in string.
The code goes:
Dim listItems As New List(Of String)
Dim pattern As String = "AbC"
Dim array() As String
array = {"ABC", "abc"}
listItems.AddRange(array)
Here I'd like to remove all items from listItems, that are abc, no matter what case single characters of item are, including mixed case items. So in this example, every items should be removed
listItems.Remove(listItems.Find(Function(r) r = pattern))
If I change pattern to match the case of item, then item #2 gets removed:
pattern = "abc"
listItems.Remove(listItems.Find(Function(r) r = pattern))
How can I find item in listItems, ignoring the case characters in pattern?
What is the code for ignoring the case of an entry while checking to see if the entry is correct or not... (i.e. in a flashcard program... given definition, asks for the name) I don't want the case of a character to affect whether the answer is correct or not.

View 2 RepliesI am trying to check if a users input contains any special characters from a list, does anyone know who I would go about doing this?
I've tried the LIKE operator:
Dim sMatch As Boolean = tTitle.Text Like "[-/,.:;*?""""<>|&'[]^%£$()_+=!#]"
but doesn't seem to work, i think special characters are used for settings.
Is there a RegEx i could use for this??
How would I check a given string for the presence of any match with a character listed in another string. I'm just looking for a binary result.
In other words, how would I write the VB.NET function called IsPresent in the following code snippet?
Result = IsPresent(AnyString, MyTestString)
For example, if MyTestString = "XYZ" then I want the following results for the given AnyString values:
MUTTON, Result = No
BUZZ, Result = Yes
HAPPY, Result = Yes
FISH, Result = No

When I run the code I am getting the MessageBox but it will state "UserName favorite color is " but does not show the color.

This is the standard way of checking if URL exists [code]....
return true; } catch (Exception ex) { return false; } But my problem is that we have to check it for around 100 URL's. It takes more then 2 minutes to check for all as it is trying to get response of all of them. Is there any way that we can check if URL exists without getting complete Response so that total response time is less.
In my code, I want to check if a referrer url exists and if the referrer url contains a specific sub string. I know how to check for the sub string:
If( InStr( Request.UrlReferrer.ToString(), "some sub string here" ) > 0 ) Then
But I don't know how to check if a referrer exists or not. No refer exists if the url is entered in manually in the address bar. So I tried this, but this does not work:
If (Not (Request.UrlReferrer.ToString() = "")) And (InStr(Request.UrlReferrer.ToString(), "some sub string here") > 0) Then
how do check if a referrer exists?

View 2 RepliesI am using Caspol.exe to install a custom Permission set and add Code Groups for my .Net 2.0 Windows Application.
I have created a Console Application that uses caspol.exe to add Permission Set and Code Groups. I first install the Permission Set and if I do not get an error, I continue to install the Code Groups
Now sometimes I need to add a new Code Group to the client machine, so I make the changes to the console app and it is executed on the client machine. If the client machine already has the Permission Set installed, it returns an error and stops the further processing.
So, I want to know if I can check whether a custom Permission Set is already added or not?

View 6 RepliesI have a small database. 2 main tables called CaseDetails and Checks.Each record in CaseDetails can have 3 checks recorded against it in the Checks table. But can only have one check of each type (check types 1, 2, 3).I have 3 linkbuttons which will take the user to the input form for each 'check'. If a 'check' already exists i want to hide the linkbutton that takes the user to that 'check type' input form (the 3 input forms have different fields).So what i need to do, is connect to the SQL database and see if a record exists for each 'check type' and hide the linkbutton to prevent users from entering another record with the same 'check type'?I have tried reading the reults into an array and examining that array, but havent been able to do so.
