Does variable total have to be converted back to string ie..Cstr(total) in order for the result of total to be displayed in the text box txtdisplay? I notice It will work if I convert it to string or If I leave total a double it will still display the result as a double. what is the correct programming practice? [code]
View 1 RepliesI've got another problem. This time I am Trying to display the contents of a folder into a textbox:
Public Class Form1
Private Sub browseFolder_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles browseFolder.Click
FolderBrowserDialog1.SelectedPath = _
My.Computer.FileSystem.SpecialDirectories.MyDocuments
[Code]...
I know the line TextBox1.Text = FolderBrowserDialog1.SelectedPath is not what I want to be doing, but thats the only thing I can get to work, but that just displays the folder path obviously. What I want is to display the contents of the selected folder into TextBox1
i want to display a value of a variable, type into a textbox.
for example
num=1234
varx=763
i=23
[Code].....
1.prompt a text string in 0 to 20 characters and then pass it as a input parameter to a Boolean-valued Function to check if the string is symmetric or not. Display the result.
2.The Einstein's equation E=mc2 relates three variables, E, m, and c. create four TextBoxes, two for the names of variables (E, m, c) and the other two for the values of corresponding variables. Based on the entered names and values, calculate and display the unknown variable in another TextBox.
I have a form where a number of textboxes are programmatically created within a flowLayoutPanel and named by adding together 2 strings.
With the click of another button i hope to have all the values entered into these text boxes stored in a text file. However, i cant seem to find a way to add strings together to allow me to retrieve the values entered within the text boxes created.
Below is the code i have so far: BTW FLP is my flow layout panel and c is my calculated nmber of textboxes that are created.
Private Sub createTB(ByVal c As Integer)
Dim x1 As Integer = 1
Dim y As Integer = 2

I recently learned how to send the contents of a vb textbox to a flash textbox which is in an swf embedded on my vb form using a vb button to trigger...
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
AxShockwaveFlash1.LoadMovie(0, "C:sample.swf")
End Sub
[code]....
This workds great, however what i REALLY want to do is the other way around.... I want to click a flash button thats in the embedded swf and have it put text into my VB textbox... The text I want to dislay is:"well done!" SO Far:I have built a simple swf with a dynamic textbox and a button. textbox is named "sampleField" and its var is: "sampleFieldVar"...button instance named "Button1" is an instance of "button".
using as2 I have put the following code onto the button:

My current issue which I've been stumped on is incrementing variable names in a string.
Without reading my actual situation, I need to know if you there is a way to do the following:
Code
'Label1 is a label that exists in a userform and this code is entered into the UserForm_Initialize()
Dim X as String
[Code]....
The reason for my label1 example above is I believe that using my current methodology- if there is a way to convert a string contents to a variable name, it should do the trick.
i'm dealing with a variable of the type string, in a "select case" code; if the string in it was "5a6-Hor" then some calculatins will be made. the problem is that the value would be "5a6", but the case related wont be applied(the compiler isnt reding it as "5a6"), although i had a msgbox showing the value of the string as "5a6", as was defined under form_load event here is the code:

I have method that I execute many times.In this method I have the following AddHandler.

Dim methodName as String = "Context_SortDescending"
AddHandler mi.Click, AddressOf methodName
This received an error (AddressOf operand must be the name of a method).

I had a look through this forum and other forums but couldn't find what I was looking for. I am new to visual basic and have spent all day trying to find the solution to the following issue.I am creating objects from a class that store information about the user of the program. Each time a user signs up the program, I need the code to create a new instance of the class, creating an object and storing information about that user. The contents of this object will then be saved into a text file.

I have the header, column heads, the student names and the averages printing when I click the print page event. I have tried multiple ways of setting this up to get the test scores to print, these are the structure array variables. When I put in the code to process the arrays testscores, I receive a run time error that I don't understand
View 2 RepliesIs there a way to display the contents of a drive (C:/) in a way similar to that of windows - pretty much just like this[url]...
Except that i need to show the files and - this is the part i really have no clue on - using the icon maybe using the Icon.ExtractAssociatedIcon method ?
So suppose there is a string: StringRamdom and you display it's contents in a listbox.
so listbox.Items. Add(StringRandom) but it should be displayed as A, B, C
not
A
B
C
While working with an excel file (.xlsx), the data I get from it is an IEnumerable(of Dictionary). When I bind this to my datagrid, I get the problem that I only see 2 columnsI've been tracing this problem and discovered that in the first row in the excel, there are only 2 values (cell C and D). I think the binding to datagrid looks at this first row to create its headers. This results in my datagrid only showing columns C and D.

I am currently going through Murachs Beginning vb.NET and have come across an problem with one of the exercises at the end of the chapter on collections. I basically have to update a simple Invoice application that was developed in an earlier chapter.It requires me to update the app such that everytime a new invoice object is created ( via pressing the new invoice button) this object is added to a queue. I am ok with this part.However I then have to edit the exit procedure so that the invoice objects are dequeued and displayed in a message box. This is where I am having my trouble. My code so far is shown below. This consists of the form.vb and the and the Invoice class.[code]I have also added a diagram of the format for the message displayed in the message box. I know I have to iterate through the queue but how can display the invoice customer name and invoice total?
