Referencing The Report Objects?
Jan 11, 2012
I'm just trying to reference report objects (specifically textboxes).For example, let's say from a form, the person has to enter a specific title each time the report is run; or they have to enter something that has to appear along side each record in the detail (List) of the report each time it's run.
How to you pull the info on a form into a report? Is this even possible in VB? (it was quite easy in Access)I've tried in the Form code something like: My.Forms.Form3.ReportViewer1.textbox1.text = My.Forms.Form2.TextBox2.TextBut of course it says "textbox1 is not a member of Microsoft.Reporting.WinForms.ReportViewer" Then I've tried adding an Expression to a textbox in the report itself in an attempt to try and pull the data from a form. The Expression for a Report textbox went something like =My.Forms.Form2.TextBox2.Text

I made a browser and its awesome but i want to reference the browser name so that i can add script to it, I am calling the new browser window "wb" cause that's what it gets named in the script. here is my code. (it labels the tab, the window, and changes the URL text field)
Private Sub wb_Navigated(ByVal sender As Object, ByVal e As System.Windows.Forms.WebBrowserNavigatedEventArgs) Handles wb.Navigated
TextBox1.Text = wb.Url.ToString()
Me.Text = CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).DocumentTitle & " - My Browser"
[code]....
It says "Browse.Name = "wb"" so thats why im trying to call it "wb". I inserted a WebBrowser on the form named wb and then tried to run it and it worked, it labeled the window, tab, and changed the URL field. So i know that the script works. Please help me, I know you guys can solve this, I'm really new at this.So my final question is... What should I call the browser instead of "wb" when I am referring to it in the first script I posted above? I am so confused. How do you refer to an object that gets created dynamically?

I would like to dynamically create an object (in my case a thread) and then be able reference that object. Simplistically put, I would like to read from a text file and then process each item using a thread (so that I don't have to wait for each item before starting the next). The problem is that I cannot think of a way to create a new thread dynamically ie. thread name so that I can then wait for all created threads before doing something else.

writing a program which stores and uses information on oil pipelines. I have a number of worldwide sites, which each have a number of pipelines. Each pipeline has a number of segments, and each segment has a number of properties like flow rate, temperature, pressure etc. There are also going to be a number of cases, so the temperature of a segment in case 1 might be different to case 2.
What is the best way to set this up in terms of objects and references? I�ve done a fair bit or reading about arrays, collections, classes and think there are a number of ways to �skin this cat�For example, if I wanted to reference the temperature in case 1, of segment 3, in pipeline 4, at worldwide site number 3, then can I do something with a load of objects and collections like the following?
site(3).pipeline(4).segment(3).case(1).temperature.value
Is it possible to have an object heirarchy, where an object has a parent object, and both objects have their own attributes and fields?

I have a tools strip menu item with dropdown items that are created dynamically.
For Each file In files
Dim newMenu As New ToolStripMenuItem(FileNameOnly(file))
tsmMachType.DropDownItems.Add(newMenu)
Next
So how would I go about setting up or creating events for these items? I need to have a check event and click event for each of the items.

I dynamically (by programming text, not drawing in GUI) created a matrix of 10x10 buttons named 'Button1' till 'Button100'. In a formula I calculate a number, say '87'. If I next want to reference 'Button87' and change e.g. the background clolor and text properties, how would I do that? I am creating a PocketPC game using VB2005.

I'm trying to learn Crystal Reports (VS 2005, VB) and per this question I was trying to drive the report with my own data objects instead of through a DB connection.
I found this tutorial and it looked promising as an answer to my question, but after diving in it only seems to apply to web development.
Am I out of luck in trying to power a Crystal Report with .NET objects in a standalone application?

I have an RDLC report that I am rendering directly to the Response Stream as PDF (rather than using the ReportViewer). In the code that renders the report, it's DataSource is bound to a List(Of ClassA) objects defined in a custom assembly. This seems to work for the most part. My problem is that I can't seem to handle the situation where a nested object is null. For example, given ClassA and ClassB (the nested object) defined as follows:
Public Class ClassA
Public Id As Integer
Public Name As String
[Code]....
the report displays "#Error" if TheNestedObject is null. If TheNestedObject is not null, it correctly displays the Name.

how I can reference a report variable in the Report Properties Code Window of a local report? I have tried Variables!Claimant.Value (for a variable called Claimant) but I get an error "Reference to a non-shared member requires an object reference." I have tried qualifying it with Report. and also with the report name in front of it but I get errors with this also.I have the variable CLaimant defined in the Variables section of the Report Properties.

long story short, I have created a ListView type control, using UserControls for the parent control and the ListViewItems. Most the of the control is written and works fine, right up to the point where I tried to replicate the 'Control.SelectedItems(0).Index' property and the 'SelectedIndexChanged' event.
Each child object knows its index value, and could pass this value via the SelectedIndexChanged event (assuming this is how it works in a normal ListView control -- user clicks on an item, and that item fires an event updating the selected index value in the parent object).
How does the child object raise an event in the parent object? I have a feeling this could be done with Delegates, but I'm still learning about their usage.

getting the following error Unable to cast object of type 'System.Object[]' to type 'OrderService.webdirect_WebLinesRow[]'. On the line
webdirect(web_companyID, web_locationCode, web_customerNumber, web_orderNumber, web_orderReference, web_orderDate, webLinesArray.ToArray(), o_Company, o_LocationCode, o_CustomerNumber, o_OrderNumber, o_OrderStatus, o_OrdDescrip, webRespArray)
I created the webLinesArray.ToArray() array as such
Dim webLinesArray As New ArrayList()
Am I missing an additional cast or something ?
