Is there code that creates a button onto the form? The button will not exist until the code is run.
View 1 RepliesI 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.

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.
This should create a desktop shortcut but instead it spits out an error that is because of the quotes inside quotes. They need to be there, I know this is the problem as I have tried without them and it has worked. Another problem though is that it creates the shortcut (when Idon'thave quotes in quotes) but wraps the whole TargetPath in quotes making the shortcut unusable. Here is my code:
Dim input As String
Dim s As String = Environment.GetEnvironmentVariable("UserProfile")
input = TextBox1.Text

Part of my assignment is to check if input to Group Number and Number of Units are correct input by making error handling exceptions...
I have to check the following:
a) group number is neither 501 nor 062
b) number of units are NOT numbers
c) number of units is NOT a positive number
So my first question is, am I checking correctly? 2nd question is, How do I make sure my Exceptions will pertain to their correct respective things (a, b, and c.. above)?

My VB application is behaving strangley. I have form with fairly large number of controls. I am using case against radio buttons. after curtain number of buttons, it stops responding to more radio buttons.

View 6 Repliesi already finish this module but while doing 2nd module i notice that my 1st module doesnt work anymore, then i checked my code, i double click the control at design time and thats it instead it brings me to my actual code of that control, it brings me to another event, like this, this is where my original codes are placed:
Code: Private Sub lblSupplier_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
End Sub then, after the poblem occurs, the control created another event like this:
Code:Private Sub lblSupplier_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs)
End Sub notice the difference, they are the same click event but the other one has an "_1" at the end of click.
1. Write a Visual Basic Console Application which creates two DateTime objects. One DateTime object should be used to store a value for date purchased. The second DateTime object should be used to store a value for date paid. See below for more information.2. Assign values to the two DateTime objects. See page 197 in your Doke & Williams book for help with this step.3. Use the toString method to display the two DateTime objects. See page 197 in your Doke & Williams book for help with this step.4. Compare the two dates to determine which date occurred first.

Anyone know of a product/solution that creates web forms on the fly? I want to allow my users to create their own web forms.
View 1 RepliesI have a Car object that does a few things, but I need the program to create New Cars without having to write the code for every new one. Basically, the user checks some combination of Checkboxes and then pushes a button. And I need the program to create a New Car with a unique name for each combination of checked Checkboxes when the button is pushed.
For example, if Checkboxes 1,3,5 were all checked, it would create a New Car that had a different name than the New Car that is created when Checkboxes 1,2,3 are checked.
But I also need the program to be able to check when a New Car has already been assigned to some combination of checkboxes, so that it doesn't create a New Car every time that Checkbox 1,2,3 are checked and instead will use the Car that was already created.
The sample program for the Chart Control is written in C#. It provides VB snippets but there appears to be a key piece of information missing or at least hidden. Can anyone explain to me what is needed to get the Chart Control working in VB.NET VS2008 Pro?Using the Chart Controls sample, I tried to create a RangeBar. The only thing showing is a big red X across the chart. Here's the code almost exactly as taken from the VB sample:
Private Sub ChartSample()

I am trying to AVERAGE 6 different fields on a DataTable, but without grouping. Just the AVERAGE. I have found a couple of examples in C#, but can't find any examples for how to do this in VB.Here is what I have so far:
Dim query = From dtRow In dtIn.AsEnumerable _
Where dtRow.Field(Of String)("FOLLOWUP") = "Alert" _
Select New With { _
.Brand_Functional_Avg = XXX.Average(Function(f) f("Brand_Functional")), _
.Brand_Personal_Avg = XXX.Average(Function(f) f("Brand_Personal")) _
}
What should I use for XXX? I tried all of the options that I could think of and nothing is compiling.
Trust me, if I could write this in C#, I would, but the project requires VB.

triangle:
