View 7 RepliesI have been thinking about creating an event calendar. I thought through the idea of how i would attempt it, but only came up with one idea; Text files, a folder for each year, and a folder for each month.. when the user creates a new event a text file gets created in: e.g. \2010\Jan\12.txt and if another event is on that same day, the text is added into the same text file. But this leaves lost hopes for my other ideas, since it will get very complicated. Like yearly events, monthly events etc.

I have a form that creates an instance of a New Class. The code is simple so there is no issues with the programming.
I can step through the code on the Main Form without issues. Stepping Into moves from 1 line to the next.
I can't seem to debug the code within the class though. I set breakpoints but "stepping into" doesn't work. The code gets executed, but it doesn't step through each instruction.
I've tried changing many of the options within Tools > Debug with no luck.
I've tried deleting files from bindebug and obdebug.
Not being able to debug my programs.
I am creating a form that creates new users and then updates them to a dataset, I have done this ok, but I am getting a runtime error when I delete a record. Please see below the exception being thrown
"Update requires a valid DeleteCommand when passed DataRow collection with deleted rows"
My code below
CODE:
So I know I need to add a delete command, but how do I write this in code and do I write it in the saveitem click event? I guess I would because the app crashes when I click save to update the dataset.
If you want a instance of an object to be created when a form loads or another class is created, you have two options:
Public class example
private IAmAObject As IAmAObject
public sub new()
[CODE]...
Or like this:
public class example
private IAmAObject as new IAmAObject
public sub new()
[CODE]...
I always use the first one. It's more type work but I think it's neater. How about you people and is there any real difference between the two?

I need to create text box at a run time.
I found the following VB NET code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim textbox1 As New TextBox

When this row GroupBox1.Controls.Add(textbox1) and GroupBox control are being deleted from Form, the TextBox isn't created on the Form after the event is fired.
I have 2 forms main_frm and copying_frm. In main_frm, there is a list view that is populated with file names. The user then clicks save and all the files in the list are copied to a folder that they choose using a folder browser dialog. When this happens, I do copying_frm.ShowDialog() to display the copying_frm. The copying_frm contains a progress bar and a cancel button. I can get the progress bar to indicate how much has been copied. But that freezes up the application. To get around this, I create a new thread (called copyingThread) that copies the files. When that thread runs though, it can't access the waitingList_lvw in main_frm. For example, in the function that the copyingThread executes, if I have this line of code: MsgBox(main_frm.waitingList_lvw.Items.Count.ToString()) the result is 0. Also, I don't get any errors and no files are copied. How do I access waitingList_lvw in main_frm from a thread called copyThread that was created in copying_frm?

View 6 RepliesI have a form which when button1 is pressed creates and displays a new form. From this form a user has the choice yes or no buttons. Each button has its own handler and script it executes. If yes is clicked i want to run the script and then close both forms. I used me.close() and that only closes the orriginal form and leaves the dynamically created on open. If I place a call to form2.close() in the yes handler sub I get an error that it is not declared. How can i close this second form?

When I launch the form it shows the blinking cursor in the 1st textbox(this is ok) but when i try to type nothing happens. Once i click the form(not the textbox-textbox works too but wanted to note it was the form) it works. I have tried doing textbox1.focus(). I have tried doing the form.focus(). Neither were successful. It may have nothing to do with focus but it seems to be that to me.

View 3 RepliesI am an experienced programmer but am new to VB. To start, I am trying to create a simple database program. (My ultimate goal is writing a comprehensive database program in 6-8 months)I have created the database and bound the fields to a form.
But what I want to be able to do is add a field to the database and then also bind that new field to a textbox on the form.The new field appears on the list in the Server Explorer window (on my left) but not in the data sources window (on my right.) The data sources windows has a "refresh" option but that does not help.When I manually add a textbox and try going to DataBindings in the property window the new database field is not listed.
