VS 2010 Errors When Trying To Produce Reports From Inputted Data, And In The Code?
Mar 28, 2011
i'm a freshman and was handed this assignment a short while ago and i'm having extreme difficulty figuring out why i keep getting the following error message whenever i click btnGenerate.Click on the form:Error1: Unable to apply this change while debugging. 'Private Sub GroupBox1_Enter(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles GroupBox1.Enter' was deleted that modifies 'Public Class Form1'. You must revert the change or stop the debugging sessionBasically the assignment is requesting that we build a 'Call Cost Calculator' and since im relatively new to this i've never worked with strings before and also get the follow errors:Warning2Variable 'sCountryBeingPhoned' is used before it has been assigned a value. A null reference exception could result at runtime.Warning3Variable 'sPhonePlan' is used before it has been assigned a value. A null reference exception could result at runtime.
My form codes:
vb
Public Class Form1 'heading Const sFormHeading As String = "Call Cost
[code]....
I reals because it's driving me mad and i'm honestly quite literally stuck and can't move on until i get this sorted.

I have a "legacy" VB.NET application (winforms) written for .NET 1.1, and re-compiled under 2.0 that produces a report in HTML via a custom XmlTextWriter wrapper that is suited for HTML. The user then would print the report into pdf if they wanted to.
That was 2003, and now technology has changed a bit, especially within the C#/VB.NET world, and customers want to skip the HTML part, and go to PDF directly. What are my options for open source, or low cost PDF libraries that work well with .NET and must support tables with pictures (generated bitmaps from code) and text.

I have this code:
Public Class Transform
Dim inputFile As IO.StringReader ' Object variable
Private Sub OpenFileDialog1_FileOk(ByVal sender As System.Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles ofdOpenFile.FileOk
[code]....
And I am getting these errors:
'Private Sub Transform_Load(sender As Object, e As System.EventArgs)' has multiple definitions with identical signatures. Line 15
'strOutputPath' is not declared. It may be inaccessible due to its protection level. Line 51
Type 'XslCompiledTransform' is not defined. Line 83

I am trying to rewrite some code and I am trying to determine if I am writing it correctly. My goal is to make sure that the old code and my new code produce the same results(i.e. are logically equivalent). Are the 2 code blocks below equivalent?
Old
If a = 1 then
If b = 3 OrElse b = 18 OrElse b = 20 OrElse b = 21 OrElse b = 4 then

I have created a program in Visual basic 2010, the program contains many different objects e.g. datagridview, textbox, buttons, graphs etc, which can all be modified by the user. The user can also select a file using 'SaveFileDialog'.
Is there a way to save all the properties associated with each object to this file and later load the program back to exactly the same state it was saved in, after the user has selected saved file using 'LoadFileDialog'? Preferably in binary.
I can do this the hard way in ASC11 format by interrogating objects user editable properties and saving them. I would rather not use this method as it will require a lot of code and any future program changes will require a lot of extra work.

I have a NumericUpDown control with a range of 10-50 and I want to have the selected number be multiplied by an amount of money to create yearly cost. I dont know, however, how to use inputted data from the NumericUpDown control in a statement because I cannot convert it to Integer and I also dont know how to call in the data even if a number is selected.

Basically, I am looking for a method on how to preview reports from a datagrid or it can be from the access database which populates the data to the datagrid (then displays this in the datagridview) in vb.net vs 2010.I believe there are two methods using the ReportViewer or using Crystal Reports, but so far, I have no idea how to get them to work. The first idea would be favourable - using the data from a datagridview (which may of already been sorted, filter etc) and be able to produce a report on that.

I was just wondering I heard you can get an on-screen help system, a friend said you can change this in the settings or whatever and when running your application you hit F10 or another key and it will come up with an on-screen help system.

I'm converting some C# code to VB.Net, as it's a language I know better, I've got some code that I can't figure out...
Dim mybtn As New ImageButton()
mybtn.ImageUrl = _imgUrl
Select Case _buttonType
Case ButtonType.Backpage
[CODE]...........
This is giving 2 errors:
Me.btnBackpage_Click = Delegate 'System.Web.UI.WebControls.CommandEventHandler' requires an 'AddressOf' expression or lambda expression as the only argument to its constructor.
And
mybtn.Command = 'Public Event Command(sender As Object, e As System.Web.UI.WebControls.CommandEventArgs)' is an event, and cannot be called directly. Use a 'RaiseEvent' statement to raise an event.

I am working on a project for school and I am encountering several errors in my code relating to the numeric up down boxes I have in the application. I have inserted my code and the error list below. I'm sure that it is probably something really simply but I am learning the language on my own and I am a little stumped here.

I have a simple windows form that i would like to send the values of a few textboxes and comboboxes to an rdlc report after saving them (I have VS 2005 standard, so no crystal reports) - it's as follows:
-1 form
-3 textboxes - textbox1, textbox2, textbox3
-1 label - label1
-1 combobox - combobox1
-5 buttons - button1, button2, button3, button4, button 5
the textboxes are labeled length, width, height the combobox is labled unit of measure and contains two options - inches or centimetres the label has text of "your total cubic inches/centimetres is:" - followed by the unit of measure selected.the buttons are labeled save, calculate, print, print preview, and exit.Having said all of the above, the save, calculate and exit button code is easy enough and is good to go - it's print and print preview i'm stuck on the solution i'm after is to take those values and send them to an rdlc report that immediately prints (calls up the default printer dialogue) without preview or anything when the print button is clicked and also have a print preview function as well for when of course the print preview button is clicked.The report has already been created with the titles mentioned above..
