Wish you all are doing fine at the start of a new year
I am a beginner developer. I am developing a website. I have few divs which made up dragable boxes enhanced by jquery portlets. see the codes below.(html).
<div class="portlet">
<div class="portlet-header"> Category A </div>
<div class="portlet-content">
[Code]....
I also have a stored procedure from the database developer that return the list of categories. Depending on the user selection, the list of categories can vary.
So i have to dynamically create those Boxes. Each categories returned by the SP should replace Category A, Category B, and so on. As i can't know the number of categories returned by the SP i just hard coded those divs. My question is simply how ? How can i achieve this?
I have to be using VB.net in VS 2010. The database is in SQL server 2008.
How can I limit the dynamic text boxes. I need it to limit to a specific number.
Here's the code of adding the textbox.[code]...
I am working on a project where I need to create dynamicly created text boxes (which works fine) and then save the values from those text boxes to a txt file.Essentially how the form works is their are a few static text boxes the user fills out and then presses a button to create a row of 7 other text boxes and they click the button for however many rows they need.Again this part work just fine, but its when I get to trying to save the values in those boxes that I run into trouble.I'm fairly new to vb.net and currently I only know how to save the static boxes using the WriteLine function, which unfortunetely doesn't work for the dynamic ones. [code]
View 2 RepliesHow will I check that the dynamic textboxes is empty;
Here's the code:
Imports System.Data
Imports System.Data.SqlClient
Public Class FunctionProcessor
Dim objcmd As New SqlCommand
[code]....
I have done this in Php with a function before. I just don't know how to do it in VB.I have a character sheet creator for a game I am making. What I am wanting to do is write a single function, where in you click on a button and it will pass the text box name (so that it knows which text box to edit), as well as the value inside of the text box (to make sure that the new character stat ceiling is taken into account).
Private Sub Button_Click
AddtoValue(Textbox1,stats)
End Sub[code].....
Essentially, I need to know what to put for noidea, and noidea2, like, byval or byref or what?
For example, I clicked the Add Text box button, so it added 3 text boxes in the form (I used Dynamic text box so it can add multiple text box). When I input data to one of those 3 text boxes and then Save button has been clicked. It should checked whether the dynamic text boxes are empty or not. If there are empty text boxes, then saving data to db should not be continued and display a message telling the user that empty field(s) are invalid.
In the code below, it saves the data even if there are empty text boxes and I think because it is in the for loop, it checks the text boxes one by one and repeatedly displays the message box that I coded.
Here's the complete code:
Imports System.Data
Imports System.Data.SqlClient
Public Class Form3
[Code]....
am having a big problem trying to make a program that will add multiple text boxes together.What I need to do is add all the text boxes together. If it is less then three leave it alone, if it is more then three then put a 10% discount on it. There are also other charges but the main thing I'm struggling with is adding the text boxes.
Here is some of my code:
Private Sub TotalButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles TotalButton.Click

Im trying to make when you click a button to make a drag-able text box. But i cant seem to find anything on creation one with a button.

View 2 RepliesI am building a very basic calculator which adds and subtracts various numbers from various text boxes when I click on the 'button'. This works fine with:
TextBox3.Text = TextBox2.Text + (TextBox1.Text * 1000)
etc but when it comes to adding or subtracting time I get completely lost.Say I want to add 50 minutes in one text box to 12 minutes in another to display 1:02 in a third text box by clicking the same 'button'I am using Visual Basic (in visual studio 2005) to program a Windows Mobile Classic 6 PDA?
Basically im trying to add 4 new picture boxes everytime a specific text changes. This is a picture developer based off the binary of a number 1 - 10 I can get 4 to change everytime the text changes but i have no idea how to add 4 everytime the text changes. here is the coding i have so far.
Imports System.Drawing

I'm writing a database program that will take various information from the user via text boxes, then save them as a *.txt file. I've already figured out the majority of that business. However, I'm having trouble programming a ListBox.
The ListBox needs to accept three pieces of information from 3 Text Boxes, then concantenate them when a button labeled 'Add' is pressed and scoot them to the ListBox (lstshowresults) while clearing the three boxes at the same time.
I'm having a problem adding multiple dynamic controls. the problem is that I can add one no problem, but when I try to add more it only adds one with the label's text = the last file name in openfiledialog. [Code]
View 9 RepliesForm1 has 2 public string variables defined and initialized to "" (an empty string).Form2 has 2 text boxes and a button. When the button is clicked the public variables on Form1 get set to the values in the text boxes.This works fine.I recently had to add a module to my project so that I could use Main as the startup item. Ever since doing that the above no longer works.The variables never get set to the values in the text boxes. They just stay empty.My Main code is simply this for now:
Dim f As New Form1
Application.Run(f)
I have written a text editor for an assignment but I am struggling on where to start on this bit. What I Want To Happen:- When the user saves there work I want the name of the file to be shown next to the name of the program at the top left hand side of the form. I am not sure If I just need to create a simple sub routine for adding the name of the file then calling the method in the save as routine.
View 7 RepliesI am trying to follow the book 'Sams teach yourself VB 2008'. It was going well until the end of hour 4. For exercise 1 I have created the form with a button and two text boxes, but cannot work out the code I need to move text between the two boxes. The Object Browser does not seem to help - am I reading it wrong?
View 14 RepliesI have some operations of Picture Boxes etc being performed. After the user finishes with the formatting, I want to give the user an option to print the work.But its the work is not done on the Rich Text Box but on picture boxes. I am not even sure, how many of the picture boxes would be there after the user finishes the job, since I have provided option for dynamically creating picture boxes as well.
View 3 RepliesSo as the name states; I am a newer coder.
This is the code i have:
Public Sub RandomNumbers()
Dim s(4) As String
Dim RandomNumber As Byte
I don't know if you can tell what I am trying to do here, so I will try to explain. I what to create for random numbers and place them into for different text boxes. I also would like to do this with combo boxes and their selected indexes. So if the combo box has 10 items in it; the new selected index would be the random number generated above.
I'm in the middle of creating an application that will be used to input customer information whilst the customer is speaking to someone over the phone. This involves the customer giving the employee information such as name, address, postcode etc and the employee inputting that information into text boxes and combo boxes that are in the application.
What I would like to be able to do is after the customers information is given over the phone, I need to be able to send that information to a database which will probably most likely be done by button click. In this case, I'm using Microsoft Access. I'm also hoping that I can do this within Visual Basic coding.
The database is set out with multiple tables which include a customer table and a ticket table and both have multiple fields such as first name, surname in the customers table. Both of these tables are in use with the information that the customer gives over the phone.
I've already asked on other forums and people are where replying giving me third party programs that I could use to implement this, something I don't really want to do.

Im trying to make a program that allows the user to view additional information via moving the cursor over the label to view (make visble) additional information, in the form of text boxes and/or picture boxes. How will i go about doing this?

View 5 RepliesI'm currently working on a program where I'm trying to dynamically create a picture box, a button, and a label for each item in a text file. Any ideas on how to do this? What I have: a plain text file with a list of numbers. Each number corresponds to a location. When that file is read, I want to create a picture box, a button, and a label related to each number. If I want to add something to the screen, all I Have to do is add a number to the file. So, lets say the file has. 1, 2
When the file loads, it will create a unique item on the display for each location. say pic1, button1, and label1 and pic2, button2, and label2. Right now, if I add something to the file, I have to go back into the editor and manually add everything. Which is a pain.
Below you will find a code sample that I have dummied up to try and demonstrate the issue I am having. However, this is just a dummied up piece of code. The actual program has noting to do with STUDENTS or TEACHERS. Basically, the problem I'm having is trying to have a CLASS within another CLASS each of which contain ARRAYS that need to be dynamic in size. The sample has a CLASS called STUDENTS that can have in theory many students, the number of which are unknown to the CLASS. I need to be able to add STUDENTS to the ARRAY programmatically.
The CLASSROOM Class should also be an Array since each TEACHER will have MANY Students. There will be only 1 Teacher for a given classroom but the SCHOOL will have MANY CLASSROOMS. Again, I need to programmatically add Teachers and Students without having predefined Array sizes. The code I have listed below will NOT work but it demonstrates what I am trying to achieve. I want to be able to reference the CLASS by using something like this ...
School(iTeacherIndex).Student(iStudentIndex) = "Rick Smith"
I feel like I should be able to use ARRAYLIST in both classes but haven't been able to get it to work. I've tried DIM'ing as ARRAY and can't get that to work either.If I can get ARRAYLIST to work then I shouldn't need to worry about expanding the array via UBOUND (if it's even possible).The REAL question is "How do I have a CLASS within a CLASS, each of which has ARRAYS that need to be dynamic in nature so they can be expanded as needed? The size of the array cannot be determined ahead of time".
REMEMBER . . . the actual program has nothing to do with Students and Teachers. This was just my way of demonstrating the issue using an analogy that I thought everyone could understand. The actual Class is much more involved.I have purposely hardcoded some values just to make the sample easier to work with. This is NOT how I normally program but is just here to hopefully make things a little more clear.
Here is the sample code . . .
