View 3 RepliesI'm trying to check a string, but it turns out to be case sensitive, how do i make a string not case sensitive??
This is what I got:

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!

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 wondering if there was a way to create a parameter for a method in VB.NET 2005, to select which case(upper, lower) to test for.For Example
Function Afunction1 (ByVal aString As String, ByVal case As ......) As Boolean
End Function
Where case is the paramter for the user to set as upper or lower.
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,

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?

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,
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
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?
View 1 RepliesI 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.
Any way to change the case of a string using the String.Format command. For example, you can do this:
String.Format("{0,50}","My Info")
And it gives it a fixed width string output, I need to allow the user to change the case. All they can pass in is the format "{0,50}" so NO .net functionality, we wrap it up for them. In VB6 you could use a ">" "<" to change the case, surely M$ must have added a way to do this?

How to restrict user to do rating only once..i m using AjaxControlToolkit Rating Control i VB.NET!
View 1 RepliesI have a ASP.Net Web application hosted on a server. I want to restrict same user to login on different machines over the network connection but with certain conditions to be satisfied. So I thought of adding three new columns to the User table so that we can track if same user is logged in on same or different machines.
Those columns are like :
IsLoggedIn : To check if the particular user is already logged in or not.
SessionID : To check if the same user instance is opened.
IPAddress : To check if the same user is on same or different PCs.
This should satisfy some of the below conditions, but it fails to satisfy some of them. Conditions are as follows :
Both computers are on the same LAN.
Each computer is accessing the application over the internet from different locations.
Each computer is accessing the application over the internet from the same location.
Some of the application hosted which means that IP address alone is not sufficient to distinguish different computers.
Some users just close the browser without logging out. So sessions may not be ended at this situation.
How to accomplish all these conditions to satisfy with my application ?
Mainly 4th and the 5th .
I want that when the application exe file is running at that time the database associated with the application shud be closed....Means...I am using the .mdb file.
