I have a WPF Keyboard Application, it is developed in such a way that an application could call it and modify its properties to adapt the Keyboard to do what it needs to. Right now I have a file *.Keys.Set which tells the application (on open) to style itself according to that new style. I know this file could be passed as a command line argument into the application.

View 1 Replieslimit the default events, properties and methods exposed from a UserControl so it only displays to the developer the new events etc that I code myself.What i mean is I have created a UserControl with a panel and 5 buttons, written 1 Public Eventonly at this stage, I have placed an instance of the control on a form in a new project, but in the drop down menu that comes up after say (myUserControl1.), there is a massive list of options, I don't want those to appear.
View 3 RepliesI've been dealing with this kind of problem in many cases now, I try to edit the properties of a button or a label or smth else from a backgroundworker or a timer and I would get the "Cross-thread operation not valid: Control 'Label' accessed from a thread other than the thread it was created on." Now what I am dealing with in the backgroundworker is 3 things: reading/writing to labels' names, editing the checked state of some checkboxes and changing the enabled property of some buttons/pictureboxes. Check the screenshot for more info.

How can I call multiple objects? Example..
nameTextbox.Enabled
addressTextbox.Enabled
ContactTextbox.Enabled
How can I call this objects with same properties...
So rather than typing them all with =True or False...
I just have to type a variable = True or false...
And where will I type the code.
I have a class like this:
Public Class MyClass
Private _intList As New List(Of Integer)
Private _avg As Decimal
[code]....
The Getter is calculating average and calls Setter to save the value. For some reason I cannot understand, the average is always 0. For example:
Dim c As New Class2()
c.Add(1)
c.Add(2)
c.Add(3)
Console.WriteLine(c.Avg.ToString()) ' This will print 0
What is the cause of this?
Is there a way to call a running application (my own) and read properties from it? In this case read and get a collection of objects and put it into a similar collection.
View 4 RepliesI'm wondering if it's possible in VB.NET to make similar properties call one generic one?A sentence doesn't explain it well so here's a code example.I have a bit field defined like this:

In my project I have a module called Functions where I have all my functions, suprisingly. I also have in there a few structures that I have made.One of those structures is called Point3D which is just used for storing x,y and z values.It looks like this:
Module Functions
'...More stuff in here...
Public Structure Point3D[code]....
However, apparently I am exposing type 'Functions.Point3D' outside the project through class 'EditBuildings'.But I dont get it because the structure is public the class is public and the constructor is public. If I make the constructor private then I can use it, but then I cant access the constructor from other forms.

View 1 RepliesI have an ActiveX component (for mapping) I am using that I need to do an action on a mouse click, but the event isn't exposed. Internally, the class seems to fire an event, as it has a LastPointClicked() method that you can call that returns the map coordinates of the last point you clicked on. I am trying to find a way to center the map on the point clicked. I could fudge it with some kind of timer that just checks to see if the LastPointClicked has changed and center if it did,
View 2 RepliesFirst let me say: I am still very inexperienced with VB.NET so there is probably something simple I am missing, or at least that's what I'm hoping. I've been writing a COM exposed wrapper class to provide access to a web service in a legacy VB6 application. I got everything pretty much working as I wanted - all the COM properties, methods and events are showing up in the VB6 app - but for one minor detail: when I used a method which made a call to the service, it was obviously only working asynchronously, so I couldn't update a progress bar or do anything else while waiting for a corresponding assembly event to fire.

I am attempting to modify the payroll application below using an independent sub procedure rather than a Function procedure I'm not sure why things are not working after I managed to get the thing to work with the Fwt function. It's got to be something minor that I'm overloking. I get the correct amount for "gross pay and "FICA", but get "0.00" for FWT (it should be 35.78) and I get 369.40 for Net pay (should be 333.62)' This is the "CalcFWT Function" version

I am new to vb.net but know a little of VB6.
I have an application with the window caption of "Checker"
Inside of the application is a text box that has the text (window caption) "12345", but it is locked.
I would like to change the text to abcdefg or unlock the text box.
I'm trying to write a wrapper to a service, which will be used by an existing VB6 project. I've got most of the basic framework working, except for one important aspect: I can reference the wrapper in a VB6 project and subs/function calls etc. work as expected, but events do not. The events are visible in the VB6 app, but they never fire.
VB.NET Code:
Public Event Action_Response(ByVal Status as String)
Public Function TestEvent()
RaiseEvent Action_Response("Test Done")
[Code]....
So, the cmdTest button code prints 'Done' as expected, but the Action_Response event doesn't fire. Is there something else do I need to do to get the event to fire?
About what audio components are exposed by the .net framework?

View 3 RepliesI have a windows forms application written in VB.NET which scrapes information from serveral web pages (who doesn't right)? Anyway, I am having problem with one particular site where partway through the page navigation my application hangs. When I press pause (or break) in the debugger, it stops on a call to System.Windows.Forms.Application.DoEvents.
Resuming execution shows that it really is stuck on this line (it does not reach the next line of code). It also hangs about the same point each time I run it (at least its consistent). Since System.Windows.Forms.Application.DoEvents yields to other threads on the same processor and then resumes execution of the current thread, I think the problem is that some other thread is not behaving well (not returning from some event handling code). I thought Windows 7 was pre-emptive, which makes me
doubt that theory but I really don't know.
[Code]...
The program scrapes somewhere between 12 and 14 pages before it gets stuck on the call to DoEvents. Does anyone have a clue why this would happen? Why would any call to DoEvents hang?

My DBA has several SSIS packages that he would like the functionality of providing the end user with a way to input values for variables in the package. What would be the best solution for creating an application that would take the user input and pass the data through to the SSIS package variables?
I can get this work locally using this code
Dim packageName As String
Dim myPackage As Package
Dim integrationServices As New Application

Problem is this requires that the user have SSIS installed locally.

I have an application which is grouped in a MainApplication and serveral Modules (DLL's) The Main Application is basicly a Form with a NavigationBar on the Left Side (like in Outlook 2003) and an MDI-Parent. There is also a Simple Login Routine on this Form. I store the UserName after Loggingn to a Property. The DLL's holds functionallity and Forms for various Sections for example there is a Employee.dll which holds functions and a form to show all Employees.
On Loading of the Main Application I loop trough all dll's in a "Module"-Folder and extract NavigationItems from them which I add to the MainForms NavigationPanel. I don't have a reference to the Modules because I want to make it as flexible as possible so that it is possible to delete a Dll form the Module directory in order to remove the functionality from the MainApplication. The Modules could work also without the MainApplication if they are Complied as an exe insted of DLL of course. This works fine so far.
