i'm trying to have a if statement that will take the users inputed value and if the value is greater then 8 it will take the greater amount and times it by 1.5 can't get my head around it, only just started studying Visual Basic so would be greatful for any help you could give me. Here's the code i've done so far on the if Statement,

Below is the code i am using for user input which works fine apart from one thing that i can not work out how to do.I want to detect if a user had inputed a character in the wrong place. The correct input is:
D:Folder name
The incorrect input is:
D:Folder name
How would i detect the extra '' at the end?

Im trying to do it myself but im not sure how you get letters inputed in a text box to determine which part in the array it is. Here is the problem:
[Code]...
i got the following things:
-A button (called "btnplayvoice")
-A textbox(multi-line enabled, called "txtinput")
-Some *.wav audio files in my "resources" (2 of them called "A.wav" and "B.wav", of course there are still some more sound files in my resources xD)Note: the button and the txtbox are in the same form.
i want to make a program with this feature:When I type "B A"(note between "B" and "A" has a space)into txtinput, then i click the btnplayvoice, it will look up and check the resources and see if the wav file exists there, if yes, it will play the related(same as inputed) sound files one by one in correct order. That mean in this case I should hear "B.wav -> A.wav" in this order.
I have an asp.net web app that uses forms-based authentication, a SqlMembershipProvider (using an encrypted password format), and a SqlRoleProvider. I need to know if it's possible to administer the users (create new users, assign them to roles, etc.) from a windows application - the powers that be don't want any administrative functionality in the web app itself.Here is the membership provider definition from web.config:
<membership defaultProvider="MyProvider">
<providers>
<add name="MyProvider"

1.I�d like to publish a free vb.net desktop application for the users to download and use meanwhile I�d like to collect usage information ex: user ip address, user�s registration information, used features, time spent� if the user allows the report to be sent back.
2.Also , in order for the user to be able to use the application, he�ll have to register it then, everytime, before the application loads, it gets verified online that it was registered, maybe validate the registration information or a valid user name and password, no critical personal information. The target of this step is for the application to be used exclusively by the registered user and maybe on his computer only.

I am very new to visual basic and was recently asked to teach a course without any formal training. I am writing a program that adds the numbers between 2 inputed numbers. I need to display the sum of the numbers between the inputed numbers and the expression used to create the sum.For example: If 10 and 15 were inputed the answer label would display the following 10+11+12+13+14+15=75..The code is properly generating the sum but I can not figure out how to display the expression used to generate the sum.

The problem, The INSERT statement works fine in the form load but not in the button click event?
I was convinced that If <expression> Then <statement [:statement]> Else [statements] in concrete form of If a = b Then SayHello() Else SayBye() End has sense. I read article on msdn on If-then-else, but I forgot why I was reading, so I concluded, that snippet above means this
If a = b Then HelloIsSaid : IsNotEnded Else ByeIsSaid : IsEnded But I have tested it now, and I see, that Else without statement is nothing more than decoration. It would be pretty good if it had function I described. Do you think its good request? Or do you know any circumstance where this Else has some function?

View 3 RepliesI'm writing something that will examine a function and rewrite that function in another language so basically if inside my function F1, i have this line of code var x=a.b(1) how do i break up the function body into symbols or "tokens"?I've searched around and thought that stuff in System.Reflection.MethodInfo.GetMethodBody would do the trick however that class doesn't seem to be able to have the capabilities to do what i want..dit 2:basically what I'm trying to do is to write a program in c#/vb and when i hit F5 a serializer function will (use reflection and) take the entire program (all the classes in that program) and serialize it into a single javascript file. of course javascript doesn't have the .net library so basically the C#/VB program will limit its use of classes to the .js library (which is a library written in c#/vb emulating the framework of javascript objects)
View 4 Replieshow to use them then before, but am still a little confused with a few aspects. Here goes:
1.) Lets say you have a method that checks for a certain condition(s) and if it fails Throws an exception. Does it have to be in a try/catch block? Meaning can the "Throw" statement exist in a block with no try/catch statement?
2.) Now lets say we have a method that has a try catch block and in it there is a throw statement. When the throw statement is executed does it first try to find an appropriate catch block in the same method or does it immediately go back to the calling method without looking at the catch statements in the current method where the exception was thrown?
3.) I created a custom exception class that inherits from ApplicationException. Next I created a method which has a catch block that catches this type of exception and does some action. Is the System(i.e CLR) smart enough to throw an exception of this type, or does it only throw exceptions from SystemException?
4.) I know that some people are more liberal in their use of exceptions and others use it more sparingly when truly strange stuff happen like the DB going down. I am writing code where I am getting some info back from the database, converting it and then storing it. Sometimes there might be data that comes back from the database and other times the field is empty and the Null value comes back. Therefore in the instances where Null comes back from the database I should not convert the value to anything, since I will get an error. What should I do in this situation? Should I let the CLR throw the exception when it goes to convert the Null value or should I check for the Null value and if it exists not convert?
5.) In general when I throw exceptions, is it sensible to only throw exceptions of the type Application Exception or are there instances where the programmer throws exceptions of the type SystemException?
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?

I have the following vb code which works as expected when it's in a code-behind page. I tried to move it to a shared or component page since I will need to use it in multiple pages:

However the "if" statement shows an error " statement cannot appear outside of a method body" and the Microsoft solution is to "move statement into a procedure or subroutine"
I want to log the ip's of the users that use my vb.net program.
First of all, is this legal?
If it is, how can i log the ip's in a textfile on a webserver?
Im thinking about a small non-visible webbrowser that sends the ip to a .txt file.
I am wanting to get the users IP address (the logged in user will be running the application under there user context on there local PC), but many PC's in our environment have multiple NIC's that have been added by VMWare Workstation, I would like to exclude these type of bridged connections and only show the "primary" NIC on the PC.The following function will get the IPv4 address, however on my test PC it is returning the bridged connection and not the IP Address of the network facing NIC.
Shared Function GetIP(ByVal computerName As String) As String
'Dim ipEntry As IPHostEntry = Dns.GetHostEntry(computerName)
'Dim tmpAddr As IPAddress() = ipEntry.AddressList
[code]....
My users have a mixture of DHCP and static addresses so cannot limit the NIC to either of these connection types. We tend to have a 172.16.x.x IP range, so is there a way to modify the above function so that it will only return a 172.16.x.x address?
My form's KeyPreview is set to True. I want to allow my users to use the Enter Key instead of just the Tab key. I have the following code in my form's KeyPress event:

If e.KeyChar = vbkeyreturn Then

It doesn't like vbkeyreturn, which I used in Visual Basic 6.0. I think I must be close to having it right.
I'm attempting to make a system that stores employees details...name address etc. I would like the users to be able to log on, see and change their own details only. Is this possible is asp.net and if so how? I'm really new at this so if you could keep answers as simple as possible.
