Display A Single Character In A Label When Inputted By The User?
Jan 8, 2012
I have been assigned a task to create a basic hangman program and I need help to figure out how to show the letters that the user has guessed correctly without displaying any of the other Characters.The word that the user will be guessing is in a label the user will be guessing letters by clicking buttons This is a piece of the code for one of the buttons the user can click to guess the letter "C":
btnc.Visible = False
Guessletter = "C"
If lblword.Text.Contains("C") Then
*this is the part where I become stuck*
End If

I'm making a program and was wondering if someone could please help me (its a console app) to display words from a string that the user has inputted starting with certain characters?

In my VB.NET application I compare words that are recorded using IPA, many of which have many diacritic marks. In one of the comparisons, I compare the words character by character. But when I iterate over the characters, the diacritic marks come out as separate characters (as I would expect since this is unicode)However, a u character is different than a u plus an accent for the purposes of this program and needs to be distinguished.

I am new to VB and seeking to create a visual basic program which controls the display of several on-screen elements depending on a single value input by a user. The user can enter anyone of 2500 values and depending on the value entered, five different display elements on the screen will change color or text. The program's response to a given input value never changes, in other words if the user enters 279, the five different display items will always be the same. However, there is no real pattern to the display items that would allow for programming an anticipated response to the input value.
My thinking is to create a large and ponderous "lookup table" in visual basic - I am assuming this an be done but perhaps there is a different or better method. I plan on creating the lookup file in Excel but was assuming I'd need to export it to something that VB could easily read. Any suggestions on the best way to do this? Does the lookup table reside as a separate .txt files someplace or something like that? [Code]

I am in Visual basic 2010 express.The user will input how big the array dimensions will be.
An inputbox will appear asking the user to type each row in the array.
How do use substrings to separate that string in into each box in the array. (probably separated by commas or spaces?)

I have created a program in Visual basic 2010, the program contains many different objects e.g. datagridview, textbox, buttons, graphs etc, which can all be modified by the user. The user can also select a file using 'SaveFileDialog'.
Is there a way to save all the properties associated with each object to this file and later load the program back to exactly the same state it was saved in, after the user has selected saved file using 'LoadFileDialog'? Preferably in binary.
I can do this the hard way in ASC11 format by interrogating objects user editable properties and saving them. I would rather not use this method as it will require a lot of code and any future program changes will require a lot of extra work.

I've been working with the substring command and after coding up all the things I needed it to do, I saw a post on here where the "For Each" statement was used basically to do the same thing.Lets say we just want to take a string apart one character at a time and add each character to a label. Which would be more efficient?I made a cheap example to show ...
Code:
ABinary = "0110 1100 0001 1011"
For x = 0 To Len(ABinary) - 1

I am writing a hangman type game and I am displaying the word to the user in a label as all *'s, but I cannot figure out how to have just one of the *'s changed in the label to the correct letter when the user inputs the correct letter into the text box and clicks the check letter button.Everything else in the program works perfectly, except for this part.[code]When I use the .Replace it changes all of the *'s to the correct selected letter.

I have a string like "Hello'World" and a Data Table with some records in it. One of those records is "Hello'World".he problem is, when I do a .Select in the Data Table, it only tries to search for the "Hello" part and throws an error on "World" because it interprets the ' (single. cuote) like the closing cuote on sql.DataTable.select("text = 'Hello'World'")I have gone through msdn doc, and it says I can escape some characters with [] brackets or f.slashes , but I just can't figure out: .select("text = 'Hello[']world'")

I am trying to do a SQL query that checks for the presence or absence of a character's occurance in a field / column as a condition to retrieve the row. In this case I only need to test for existance of the specified character and in a similar query to test for the non existence. Not where it is or how many, just is it there or is it notI am using VB express.net 2008 and it uses, I think, MS SQL Server 2008.Using VB's instr() I can tell straight away if a string does or doesn't contain a character, but I would like to know this before I retrieve the row.
using the
WHERE .... and [mytable.myfield] LIKE 'Q'
or
WHERE .... and [mytable.myfield] NOT LIKE 'Q'
produces a result, but not a correct result. It does something but I can not say that it is working even part way.CHARINDEX gets an undefined function error MATCHES also gets an undefined function error?CONTAINS looks like it should work but I am still getting sytax errors with it, so I don't know how to use that predicate yet.

I have a few problems i need to solve. Firstly, I am looking for a piece of code i can use to display a picture from a bank of pictures. It will work on the basis of generating a random number and loading a picture that corresponds to that number.
i.e. Dim RandNumber As Integer
Dim RandClass As New Random
RandNumber = RandClass.next(1, 10)
If RandNumber = 1 Then
Picturebox1.image = picture1
[Code]...
Secondly, can I then use subsequent picture boxes to display pictures from the same bank of images, without displaying the same image? Finally, I then need to be able to click the picture or a button beneath the picture to select it as an answer to a question and then the whole process starts again.

I have been tasked to create a Visual Basic console script that asks the user 5 times in a row to input a number into an array (sales figures in thousands), Then you display these results as a sort of tally chart.
For example for the data: sales(10,7,12,5,15)
The output would be

I'm a seasoned (long time) MS Access VBA programmer working to learn VB.net. I had a wingding character in an Access app that I'm trying to use in VB.net, but have not found how to do it yet. After 2 hours with Google and still no answers, I thought I should try here before giving up. If I need to use GDI+, please point me to a step by step explaination. The ones I have seen so far expect too much prior knowledge in VB.net.

I got a string array & I need to show the contents of it to a single label. It acts like a clock. The thing is I tried with everything I could but I failed. This is the code I've been trying. Its in vb.net. And theres a thread running to slow down the loop so I can display the contents in a label for 2 seconds.
Dim j As Integer
For j = 0 To readText.Length
label.text=readText(j)
Thread.Sleep(2000)

I'm trying to use the timer (not a Timer object) in a Do... Until loop. I want the loop to put a single variable into a label. When I do this it works and puts the value into the label (lblOxygenReading):
If btnGetOxygen.Text = "Get Oxygen Reading" Then
Select Case True
Case rdoColorWhite.Checked
strCurrentColor = "White"
Case rdoColorRed.Checked
[Code] .....
It goes through the Do loop and the For.. next loop but doesn't change the label. Visual Studio doesn't show any errors when I'm writing the code, but when I run it, it hangs somewhere.
