If Palcheck1 Is Greater Than Palcheck 2 Then It Is A Palindrome?
Jan 12, 2010
I am working on a project for the next week of my course and have the code built already and running but there was one section of it that looking at it I just dont understand why it works correctly.[code].....So i get that the second if statement here says that is palcheck1 = palcheck2 then its not the same telling the program its not a palindrome. But in the first part of it if palcheck1 is greater than palcheck 2 then it is a palindrome.

I'm having a very difficult task here. I need to analyze a certain text and find the minimum number of characters it needs to become a palindrome. The text will not have any special characters or numbers, just alphabet letters. Now, I've made some progression and have tried a lot of situations correctly, but in some situations I've gotten wrong outputs on the MINIMUM number of characters needed. I've tested the below texts:

I need to create a a palindrome checker program. Now I know how to check a simple palindrome by using the reverse method however I am unsure if the palindrome had special characters or spaces. My question is what is the code for removing spaces and special characters from a string using loops and if statements. Also we cannot use arrays.

I need to create a code using String Compare() and Cases to figure out if a word, phrase, or what is typed in a textbox is a palindrome. If it is, a message will appear in a label under the textbox that reads, "What you typed is a palindrome." Or, "What you typed is not a palindrome." , if it is not.

I am having problems getting this program to run. It is a palindrome checker, you are suposed to enter a word or a phrase and determine weather it is a palindrome. The code is suposed to contain a Boolean valued function, and should display true or false if word(s) are palindrome.
Here is my code
Private Sub btnAnswer_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnevaluate.Click
Dim Input As String
If IsPalindrome(Input) Then
txtAnswer.Text = "True"
[code]....

I'm working on a problem where i have to allow a user to input a word or phrase and then determine if it is a palindrome (a words that reads the same forwards and backwards) . It also says that the program should use a Boolean-valued function procedure named IsPalindrome that returns the value True when the word or phrase is a palindrome and the value False otherwise.

I am working on my program as I have created picturebox1 and splitter1 in my program. I am coding on the if statement as I am trying to compare on the value that if they are less than 184, then do something.
Private Sub PictureBox1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PictureBox1.Click
If Splitter1.Location <= New System.Drawing.Point(184, 0) Then
[Code]....
I know that I can't compare the value using with <= which I will only have to use = instead of <=, but i still want to compare with the value that if it less than 184, then do something.

Need to return the greater of 3 values. Each value is based on user input and system calculations. Requirement = the greater of (Req1, Req2, Req3) Have tried a number of "If" "Else" and Ifs within Ifs "<" and ">" combinations without consistant results. This may seem simple to some but I am relatively new to VB. My search on MSDN was not fruitful.

This makes no since to me I have a textbox that the user will put in information that I need to cut off so I wrote this code
txtMatID.Text = Trim(Mid(txtMatID.Text, 1, (InStr(txtMatID.Text,
"-") - 1)))
The user will imput a number value then a - then some words after that. I just want the number value. But when I try to debug the app it breaks on this line of code with this error. Argument 'Length' must be greater or equal to zero.

I disabled an exception because it was bugging me i couldnt find an intermittent error. My program reads textmessages from a phone, however a problem sometimes arises, and I am slowly pinpointing the areas of the code that cause issues. I have found however that it is sometimes here:
'Get a string of certain length
Shared Function GetString(ByRef PDUCode As String, ByVal Length As Integer) As String
[Code]....
check to see if length is zero AND thereofre try again in a moment, (because it usually works second time for some reason). I can think how to get around the exception

Say I convert some seconds into the TimeSpan object like this:
Dim sec = 1254234568 Dim t As TimeSpan = TimeSpan.FromSeconds(sec)
How do I format the TimeSpan object into a format like the following:
>105hr 56mn 47sec Is there a built-in function or do I need to write a custom function?

I have two columns of numbers that hold team scores for different events. I am looking for a OO way to Color the textbox of the team with the highest score in each event. I know the following will not do it (without writing a complex set of If Then Statements) but I think it might paint a clearer picture of what I am trying to do.
VB
Private Sub ColorWinner(ByVal crtl01 As Control, ByVal crtl02 As Control)
If CDec(crtl01.Text) > CDec(crtl02.Text) Then
crtl01.BackColor = Color.Gold
[Code].....
The controls are always going to be text boxes. So basicaly I want to determine the text box with the highest value and act on it without having to write a complex series of nested IF Statements.

I thought I had this sussed until I then wanted to filter between two values or greater than or less than two values. I have searched and searched all over the web for this and I just go round in circles. This is so frustrating why is this so difficult to find something so basic (anyway that is my rant). I have something like this but am totally confused and do not understand what I am doing now: how I get this working in plain English.
Me.BindingSource.Filter = String.Format("DeliveryDate >= #{0:MMM/dd/yyyy}# And DeliveryDate <= #{1:MMM/dd/yyyy}#", dtpStartDelDate.Value.Date, dtpEndDelDate.Value.Date) _
& String.Format("JobID >= {0} AND JobID <= {1}", txtStartJobID.Text, txtEndJobID.Text)
If I run this with just the date range filter it works fine it is when I add the second filter for the Job ID range I get the following error; {"Syntax error: Missing operand after 'JobID' operator."}
So I it is this line I have the problem with:
String.Format("JobID >= {0} AND JobID <= {1}", txtStartJobID.Text, txtEndJobID.Text)

I have data which can be put inside listboxes, I then proceed to save the data into a textfile then attempt to load it. This all works great until a number of over 1000 appears because it's read as 1,000 and VB thinks the Comma means to go onto the next field.
'put record into the line in correct format
sLine = sCallCentreOperatorID & "," & sCallCentreName & "," & sQuoteNumber
sRecord = reader.ReadLine

I have a datagridview where I have added a filter. What I am trying to do if the user leaves the field blank I want all the records to show. The field I am filtering on is an integer. I thought I could declare a variable and if the field is blank include all records greater than 0. This would return all records as the number will never be below 0. I tried this but can't get it to work:
HTML
If txtFiltID.Text = "" Then
sSerialID > 0
Else
sSerialID = txtFiltID.Text
End If
'Refresh dgv on filtered criteria
Me.VJobLinesTableAdapter.FillByFilter(Me.DsJobs.vJobLines, sSerialNo)
It works fine if the user enters a value.

I have a simple routine to find the next object based on a name property in an un-ordered collection of objects. I go through the collection and collect all the names in a List(of String) adding any names that are > my current name, which should give a list of everything that comes after the current key. I then sort the list using the default .Sort() method on the List(of String) and take the first item in the list, which should be my next item. I do the reverse to find the previous item, add all items < my current name, sort, and take the last item in the list.
However, this method skips over some items. For example I have items named 1210, 1210-ADA, and 1210_ADA_DB. Using this method, getting the next item skips the middle item 1210-ADA and finds 1210_ADA_DB, but finding the previous item seems to work.

I'm building an app that does calculations (in dollar amounts). I want to buildin a constraint that says the value entered into text box must be greater than 0. If the user does not follow this rule, I want them to get an error message.I have the calculations built and the error message, but not the constraint statement i.e. if users enter negative numbers the ouput is negative, which in the context of this app makes no sense. how a statement that would require the value entered into a text box to greater than a value.
