I'm expanding upon a tutorial we have in class for a cash register. The basic program is to put the name in, put the price in, then manipulating labels display the item name, price, tax, and price after tax. Three buttons being calculate tax, clear the form, exit the program.

I created a program that has serval labels on a form and a listview object. It has a button that when clicked reads a textfile and loads up values in the listview object. I then can click and drag text from the listview box to any label on the form and then the program removes the value from the listview box. Now, my question is how can I instruct VB to save these values in the text property of the labels so that the next time the program is loaded the labels will contain the values loaded during the last run time session?
View 1 RepliesSo far I have a button that calls scan.bat which simply runs net view and outputs to file.txt. I then want to strip out all the gumpf so it just leaves the names of the PC's in the list (not the remarks and all that).I'm new to all this, so it might not be the most elegant way of doing this!

The homework assignment goes like this: write a menu-driven program to manage an employee list. the names should appear in the listBox when the form is loaded. When a name in the listBox is highlighted the name and number txtBoxes are loaded with the correct name and employee number. Use the Update menu items--modify,add,delete to edit the listBox items.When the Exit menu item is clicked the new employee list should be written to the text file and the program should terminate.
Well, the first part was completed successfully, but when I tried to delete a name and number I recieved an error box that said "InvalidOperationException was unhandled", "sequence contains no elements" that pointed to line 35. msdn and help were no help, talked about dataset tables? Did I use the incorrect syntax? Once I resolve this issue, the other two--modify,add should be similar, but then how do I reconstruct the text file so that it will properly load the next time the form is loaded?

how to permanently save to text files then re-open all of the information again using SFD and OFD. Now my teacher has come back at me and said that i need to be able to save the information from multiple text boxes and have the text in certain labels to also be saved into the one text file (the labels need to be done because it is a database and these labels are like the fields and the right text box needs to match the right label)

I created a telephone number form where the user enters the telephone number in a text box as (nnn) nnn-nnnn. The first 3 digits in parenthesis are the ISD code, the next three are the area code and the last four are the local number. I need to separate out these three fields of the phone number and display in three separate text boxes labeled appropriately. Now, suppose the user enters the phone number in a text box as a continuous string of 10 digits, where the first three represent the ISD code, the next three represent the area code and the last four represent the local number. I'm lost as how to change this string into the form (nnn) nnn-nnnn. This is what I have

i have an assignemnt in my visual basic express 2008 class, were i have to type in an image name, like paris.jpeg,and automatically manipulate the file to be called paris-steg.png. Once this happens i click the manipulate image button and the image should be altered so that paris-steg.png has a message hidden in it. Then i have to decode that message. At this point im having troubel getting the file name to automatically appear as paris-steg.jpeg, and you will proabbly see why with my code. I need to know how to do this. The way i have it, i basiaclly add -steg.png onto the text typed into the text box, this doesnt work when the user types in paris.jpeg as it comes out as paris.jpeg-steg.png. heres the instructiosn and my code

In this program you should read text from a file one character at a time instead of one line at a time. If <tt>sr</tt> is an IO.StreamReader, then <tt>sr.Read()</tt> will return an integer that is the value of the next character in the file. Use <tt>Read</tt> instead of <tt>ReadLine</tt> in this program.You can check whether a file exists by using the code <tt>IO.File.Exists(filename )</tt> . The function will return a Boolean value (True if the file exists but False if not).
You can check whether a string ends with a specified pattern by using the <tt>EndsWidth(pattern )</tt> function. For example, if <tt>s</tt> is a String, then <tt>s.EndsWidth(".txt")</tt> will return a Boolean value (True if <tt>s</tt> ends with the pattern but False otherwise).In a string, <tt>IndexOf(pattern )</tt> gives the first position where the pattern exists, but <tt>LastIndexOf</tt> gives the very last position where the pattern exists.The code <tt>s = Chr(i)</tt> converts the Integer <tt>i</tt> into a character and assigns the character to the string <tt>s</tt> .
I am creating a program to simulate a tenpin bowling scoring system, and I'm using labels with the following name structure:Player1Frame1Ball1, Player1Frame1Ball2, etc.. I have following variables also: CurrentPlayer, CurrentFrame, CurrentBallI am hoping to use these variables to specify which label I would like to check the value of (the score achieved, placed in the label).

I have a simple in VB/ASP.NET form containing two text boxes, I am attempting to apply some validation to the first text box using JavaScript. This is the first time I have attempted this and am having some trouble.I have a label beside the text box stating an error, this labels visibility property is set to False. I wish the labels visibility to turn true if the text box is empty when the user loses focus.For this I have used the onBlur option within the tags of the text box. It then calls the JavaScript function and should set the label to Visible but it does not. I have tested to see if it is entering the function by using an alert instead and that works. The problem seems to be trying to alter the visibility property of the label.
Here is the portion of my code:
The JavaScript:
function myRegEx(frm) {
if ( boxUsername.value == "" ) {
invalidUser.visible = True;

so i have this code which is trying to allow the user click the label (of which there are 26) and then decide whether the letter in the label matches the letter that has been generated in the radio button. I KNOW there is a more simplified to do this and much less code to write but i cant work it out. this is an image of what im trying to achieve but instead of buttons change those to radio buttons x 3.

View 3 RepliesWell im currently developing an application for public use, I have a login screen in which the user enter's their registered credential's and the progressbar loads by increments of 3, now i placed 6 labels ontop of eachother and where the progressbar coding is i put:
If Progressbar.Value >= 1 Then
Label3.Show()
If Progressbar.Value >= 20 Then
Label3.Hide()
Label4.show()
And so on up until Label8 Show at 100%,
Now the problem is... As i have placed the labels ontop of eachother i need them hidden until they are called to show, i have tried adding a background worker to do this but have had no luck, all i see is the labels overlapping eachother when i run my application when i want them hidden untill Label3.Show() is called, and then to display them as they are called and hide them when another one is called to show...

View 3 RepliesI want to randomly input a text line from a .txt to different labels in my program. So far I have this:
Dim FILE_NAME As String = "question.txt"
If System.IO.File.Exists(FILE_NAME) = True Then
Dim objReader As New System.IO.StreamReader(FILE_NAME)
Dim question(5) As String
Dim line As String = ""
[Code] .....
This works perfectly, but as you can see there is no randomization, it just runs through each line. I want one out of every three lines to be chosen. My text file, on each line, has question tab answer tab answer tab answer tab answer tab correct answer. So for the first inputted question i want it to chose one of the first three lines, second question chose a line between line 4,5 and 6. etc.
So my issue is that I created program that writes a text file in several lines but I am having trouble reading those lines in separate labels on another program. I don't want them in one label but separated with one word to one label.
how can I put a counter on the time a new file is added to the program? I can't seem think of a code for it.
This is my coding so far but I feel like it's not really giving me anything
