i have this as my code goal is tocreate a application that displays counts of occurences of each digit in a number entered by a user , is their another way without doing it with the case statement?
For x = 0 To userInput.length - 1
Select Case userInput(x)
Case "0"

I was wondering if there is a vb.net xml function that counts the number of occurences of a particular node. I would like to count how many </row> nodes i have in an xml file. i have done this by reading the file into a string array and adding 1 to a counter everytime a </row> element is on the line, but this seems very low tech and i was wondering if there was a vb method for counting this instead?
View 4 RepliesAfter executing a query with LINQ to SQL, the result I have is an arraylist (.ToList) of items with ID numbers. The number of items and their occurences will vary with each query. would simply like to count the occurences of each specific ID in the list. How do I do that?? The only count function I know of (.count() ) is for a count on the entire list. I've also I've been reading on how to loop through the list items but I don't understand how I can do that if I don't know how many specific ID's there will be from each query
View 3 RepliesI am attempting to write a very basic console application which simply counts the number of times a word appears in a sentence. This sentence is input by the user, as is the word to look for.(I also need this search to ignore the full stop and case, but I'll try and do that myself)For example:
Sentence: "This is the last time that I'll say this."
Look for word: "this"
Expected output "2" (as "this" appears twice in the sentence)
I have written some basic code below, however, the output is a boolean value rather than a count of all the times the word has been used.I have a very limited knowledge of VB, so the solution is probably going to be long winded and simplisitic. I am a mature student at university, hence the reason I am writing these odd looking applications.

I've written an app - that use httplisteners to talk to other winforms (they will be services but are now simple form apps so I can easily show stats as they communicate). One UI app talking to three other "service" apps - all talking to each other as well...Everything uses multi-threading...At any rate - how many threads do I have available - I see that most of the apps seem to run "two or three" consecutive threads - but not more than that.Is that just a byproduct of running in the IDE - or is there a max of number of threads available?When more threads are asked for than are available - do they simply wait to get started for a free thread to become available?

View 9 RepliesI have been working on an angle calculating program. I have incorprated a feature so you can type the angle and the program draw it. I have since added a few new features and updated everything as such. For the life of me I can't figure out why the draw angle has stoped working. let me just paste some code.
Imports System.Collections.Generic
Imports System.ComponentModel
Imports System.Data
[Code]....
Right, the program isn't so complicated. The important bit is that you type an angle in textbox1 and hit enter. Then what happens is the angle is calculated against a base line (one of the new features is that this base line can be moved from left to right and center.) the problem occurs when you hit enter, the program doesnt actually draw the line for you.

I'm making my own ID field (highest number + 1) and using it when I insert a row into my tableadapter, and I've tried two ways...
Ordering my dataset by ID descending and picking the first row does nothing for me.
I've tried building a datatable and ordering it descending and choosing the first row. This works great until you get to 10... Then it counts 1, 10, 2, 3, 4...
How can I make a textbox, label, etc be the next ascending number in my column Highest Number + 1?
I have been using this code for a long time now and it has always been accurate. I recently tried to convert a large string from one base to another and some weird stuff happens.

I'm trying to figure out how to make a number be randomly picked but only picked once when a button is clicked. I've got the simple random number code down already but I can't seem to figure out how to have it picked only once.This is basic random code that I'm using right now.
Randomize()
Dim value As Integer = CInt(Int((14 * Rnd()) + 1))
It picks out a number from 1 to 14 and returns it as an integer in "value", and I'm using to set that to open a specific form but I don't want that specific form to open more than once in a session. So if the number three was already picked out then it could never be returned ever again.
I have a question about how to get a button to check for a textbox contents, and then compare that with data in my fairly simple database (It's meant as a login procedure).
Here's my database:
It has 2 values, 1 for the manager and 1 for the Admin
Here's my Login screen:
Now...
Everything works just fine, all the code is correct so all the buttons work. For the program i'm making, there's 3 types of users, 1 user who can only change how much money a customer owes the company, 1 user that can add new customers and other little things and one Admin who can change pin numbers and manage backups and stuff like that. For the last 2, i need pin-number/password protection obviously.
The user should enter the pin and then press ok, after which the ok button checks if the pin number the user entered, corresponds to either identifier 1 or 2 (5566 or 6655 for now) and if correct, show the user the next form.
Decimal number in my textbox I need to round to the nearest even number. Is there any idea how to do it?
