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?
View 7 RepliesI 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 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 am trying to strip the first 75 characters from various strings (sentences / phrases) and it seems right but I need to ensure that the now words are truncated in the process. Meaning that if the 75 character is part of a word it needs to fall back to the beginning of the word or nearest space..
I thought of stripping the entire string into separate words and then counting the length of combining the words and stopping when I reach the target but what do I do in the case when it is not a valid sentence just a bunch of characters jammed together. I thought of using grammar parsing tool libraries and parsing into tokens etc but that seems to over complicated.
if text.length() > 75 then
ctext = text.remove(text.length, 75) & "..."
endif
I put elipses at the end but using the above I also get the error:
does anyone have any better suggestions.
I have an HTML string and in that string are certain variables that I need to replace with database values. The variable names are dynamic but all begin with the characters "@@" (just two ampersands, no quotes). Is there a way to get all the words in a string that start with "@@"? I'm assuming you would use regular expressions, but not sure how to begin.
View 2 RepliesI have a situation where a user can enter just about anything they want into a text box.Whatever they enter in the box, I need to split the string into an array of strings where each item is one word. For example, if the user enters All State Insurance, I split that into a string array:
sParams(0) = "All"
sParams(1) = "State"
sParams(2) = "Insurance"

I have a program that requires a string. The string is 20 characters long. The string also have to be split into 2 words the first word is 12 characters and the second is 8. If the strings is not 20 characters long I get an error. I wanted to know how can I get the program to start back over and let me enter another 2 more words if the string is not 20 characters long. At the moment after I get the string is not 20 characters long error it continues to read the rest of the program but I want it to stop after an error and let me start over from the beginning.
View 3 RepliesI currently have a list of words in a text file sorted in to alphabetical order and put into lower case, but I would like to be able to also display the line numbers on which these words are associated with.. but only one instance of.
For example,
"This is a random text
file that I
have just made
up this second"

As you can see above, I would like to show that "this" for example appears on line 1 and 4. Hopefully tabbed so that it keeps a nice look to it.
I have recently created an application where a lot of data is loaded into objects when the application starts up, and other data as it is required. For example if the user requests the catalogue page then it will load all the top level category data into objects of type Category. This will then stay there to be used by other users (who will therefore not have to load this data into objects) and can be altered by admin if they happen to login during the same application instance. I know this is not the most efficient solution, as pointed out below, but it works and the page load, at the moment, is not too long. It is very quick if most of the required data is already loaded into objects. It is also tailored to the business' needs - unlike other techniques such as Linq-to-SQL.

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 have a string of characters, but I would like to have a string of hexdecimal characters where the hexadecimal characters are converted by turning the original characters into integers and then those integers into hexadecimal characters. How do I do that?

View 3 RepliesI need to create a console program that allows you to enter a string, of which is then outputted in reverse.
Sample:
Input: Diewas
Output: saweiD
Apparently I need to find out about strings and will also need to use a loop.
Not sure if too many people know this, but the following line will cause an error:
GroupName.Substring(0, 3) = "jt_"
....if the length of GroupName is less than 3 characters. I always thought it would simply return whatever characters in GroupName, but no, it errors. I must be thinking of the old VB6 days.So, I now have to change the code to:
If (GroupName.Length > 2) Then
If (GroupName.Substring(0, 3) = "jt_") Then
Note that the two comparisons need to be on separate lines. If they are on the same line, such as:
If (GroupName.Length > 2) and (GroupName.Substring(0, 3) = "jt_") Then then the code will still fail as the length command is executed at the same time as the substring command- which will cause the error when the GroupName length is less than 3.Just thought that those of us not aware of this should be!

View 3 RepliesI got a text file which I want to display on a text box. The text file has data sorted by date (the oldest one at the first line)
What I want to appear on the text box is just the opposite, the newest one at the first line, and I don't know how to do it.
Does anyone know how to open that text file and display it in inverted order?

Im creating a hangman game. I have a list of words and from that list is a ranomdly selected word. What i was thinking of doing was having the program take the amount letters there are in the word and make that many text boxes on the screen probebly .5in x .5in and .2 in apart. I also have an onscreen keyboard. Whenever the user picks a correct letter from the keybaord, it will show in the correct box.
View 2 RepliesI've created an application that is supposed to map a network drive as soon as it starts using this basic sub:
Private Sub DesktopAssistant_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

It works perfectly fine when I start the application, but when I do RunAs and start the application as another user, the MapDrive function does not seem to execute. Everything else in the application works when running as another user, just not on-load events.
My app (which runs ok as a standard user) requires updates to be installed, but I don't want to have to input the administrator username/password each time nor do I want to increase user privileges to administrator.
I have a windows service which handles the downloading of updates etc (running as Local System) but the start command needs to come from the main app (running as a standard user). This is not permitted and I get Access Denied.
I understand why this is happening but is there an alternative way to achieve this? I want to handle program updates as the standard user without using ClickOnce or installing to a non Program Files folder.
I have a two buttons: Previous Week & Next Week When i run the app the LabelDate needs to shows up "May 31, 2010 - June 6, 2010" When i click a previous week button i want to set LabelDate's text to "May 24, 2010 - May 30, 2010" If i click Next Week button i want it shows up "June 7, 2010 - June 13, 2010" Means it should always display previous/next week starting from Monday and ending with Sunday.

Im trying to work out what the best way to match 2 strings together, but with a difference.
String1 = "dog cat bird chair book table"
String2 = "the dog chassed the cat around the chair"
No I know I can break string1 up by space character and check if each word appears in string 2, I would prefer to not have to do that.If there some sought of regex that would take a group of words and retrun how many of them matched ?
