I've hit a small issue on a project of mine. I have a comboboxcolumn on a datagridview and the items list has the items ("enabled" "disabled") as the values (stored at design time). When my sql table gets the value "Enabled" or "ENABLED" stored somehow as it's value then I throw a dataerror.
I am trying to avoid this dataerror, I was told to modify the value during the cellformatting event however with my experience the dataerror fires before the formatting. What is the workaround to this behavior? As a textboxcell type the error is not present, it's all because of the case sensitivity of the "items" list on my comboboxcell

visual basic.net is case insensitive so it allows the coder to write without caring or remembering the casing of variables. it also relieves from the 'undeclared variable' errors if you use the variable in another case than the one used in declaration. The fact that its line termination is a line feed makes it even more readable unlike C# or c++ that need good care in the casing and contineous war with following up with the {}, matching them and figuring out which is for which.
my question is what are the advantages of c# over vb knowing that both get compiled to MSIL so there is almost no performance difference between the two languages?
I was debugging one of the applications I work on and came across an interesting issue. For those unfamiliar with VB.NET, variable names are case insensitive. Therefore,
Dim foo As Integer FOO = 5 System.Console.WriteLine(foO)

Variable names in VB.NET are typically case insensitive. The GetProperty method on Type seems to be case sensitive when it comes to the property name. Is there a way to call this method "VB.NET style" and ignore case? Or am I SOL here and need to apply a C# mentality and worry about casing?
May i know how to implement the case sensitive detection in VB for the login part, so if a user registers in "key" for his password and keys in "KEY" for his login, the system will actually kick him out.[code]...
could someone help me with some simple coding methodology for doing database searches within the ExecuteReader function that will return results regardless of case?For example, if the variable to search for within the database is John Smith,I would want the search to be successful if john smith is the user-provided variable.
I have the following code that verifies user id and password, which are retrieved from SQL Server, but I want the verification of the password to be case sensitive.
I just came across an interesting scenario. I have a class in C#:
[Code]...
As C# is case sensitive, this will treat the two variables A and a as distinct. I want to inherit the above class in my VB code, which is not case sensitive. How will the VB code access the two distinct variables A and a?
i have to find a string in an array. i am using array.indexof method to get the index of matched item. now problem is that indexof method comparison is case sensitive and i cannot restrict user to provide case sensitive string.[code]
I've been using text.indexof() to see if a string is located inside another string, however is it it possible to do a case sensitive/insensitive search option? I've been looking around Google and not having much luck with it.
A huge bonus would be if it could count the number of occurrences inside the string!
I am working on a VB.Net application that needs to access a web service that I am nearly certain has a C# backend. At bare minimum, the backend is providing classes to me that are differentiated only by case, and within a number of those classes, there are properties and methods that are only differentiated by case.
VB.Net is case insensitive, and it sees a number of these items as being ambiguous.I've thought of a few ways of dealing with this, but I would like suggestions before I go down a road that is likely difficult.
Here are some ways I have considered going about it.Modifying the generated code for the wsdl. This has presented problems in responding as the xml output would no longer conform to the webservice requirements.I think there might be some attributes I could use to override this, but I'm not sure what they are yet. Even so, this web service gets frequent updates and I would hate to have to keep refixing the service every time I refreshed it.Creating a csharp wrapper project where I expose the underlying classes with different names. Primarily through inheritance. Although the big problem here has been the issue with properties and methods that are only differentiated by case as well.
I'm sure at some point I could get one or the other of these solutions working, but if anyone has any better suggestions that I'm not thinking of,
Is there anyway to use LIKE operator in VB.NET as case sensitive or insensitive during runtime? For example use a flag to do case sensitive or insensitive comparisons.Obviously this can be done by simple converting them into lower case and forcing application to Option Compare Binary but maybe there is a better way to do this?
I am creating a login form for an application, everything is ok but I have been asked to make the user name and password text boxes case sensitive, by which I mean if a user entered the following
User Name: vbwizzard Password: youwish
a error message would be shown If the user entered
User Name: VbWizzard Password: YouWish
The information would match what is in the database and the user would be granted access.I just need help with making the text boxes case sensitive, the rest I am ok with.
How do I create a Login Verification routine (Login Form) and make the password case sensitive?Please remember to mark the replies as answers if they help and unmark them if they provide no help.

I'm building a listview search feature in my app. (See the code below). It works really well, except if you search "T" then the code removes all items, if you search "t" then it removes every item except for those starting with "t". Is there any way to make a 'like' statement, or use some kind of wildcard to make the statement not case sensitive?
For Each itm As ListViewItem In ListView2.Items If itm.Text Like TextBox1.Text & "*" Or itm.SubItems.Item(1).Text Like TextBox1.Text & "*" Then Else
I have a vb.net application that uses my gmail smtp server settings and my password to send me the users feedback through the email, (I don't want to show my email to the users)
The problem is I want to store these data securely in the vb.net application so that It's hard for any hackers/crackers through (reverse engineering or programs like cheat engine) to get my gmail account data.
I am testing out this code which creates a excel file, and then call a sub to insert data into the file. The excel is created, but the function is not inserting the data. I am getting a error "External table is not in the expected format". I do not know what could be the problem.
This is the code below:
Imports Microsoft.Office.Interop Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
I've found the ability to make meaningful Intellisense-enabled comments on my functions and sub routines absolutely priceless.
I'm wondering if I can do the same when an Enum is defined. I'd like for each Enum highlighted in the drop list to have some information associated with it. Can that be done?
Can I display two fields of a data in a combo box. E.g. when I have to select a customer, its name and city should be shown.... Like... M/s Ananad Traders, Mumbai M/s Anand Traders, Kolkata and so on.
