Technology - AJAX - Workflow - WCF And WPF
Jan 3, 2011I have worked on .NET 2.0 technologies and now that I want start learning newer technologies, I am currently very confused on how to proceed.
New technologies I am considering consist of AJAX, Workflow, WCF and WPF
Here is my dilemma:
1. Where should I start first?
2. Which technology would allow me quicker understanding?
3. Is there any specific sequence to this learning?
I understand the questions might be stupid; however, this would help me concentrate on one instead of all over the place and archiving nothing.

View 3 RepliesFinding The Input About Program Workflow?
Sep 18, 2009I have a program that pulls orders from the database and prints packing slips and labels for the warehouse. There are 2 reports that print out every time and the are potentially 7 others that could print for each order. all of the reports will use the same basic information and just present it in different ways (i.e. label, packing slip, international paperwork, etc). the program we are currently using was written in a rush and I know is not efficient. I am pulling the same information several times for each run. I am trying to redo the program the correct way now. What I am asking input for is what do you think the best way to approach this is. I am currently using the System.Collections.DictionaryBase to store all of the information I need. I am thinking of creating more of those to store the information for each of the reports, but that still doesn't seem like the most efficient way to do it either.
View 3 RepliesWpf - Workflow Designer Line Onclick Too Thin
Apr 12, 2012I'm making a workflowdesigner to create workflows on a canvas with wpf and vb.net. I have made it possible to draw lines(relations) between objects with a nice function. Now I want to implement a way to delete a relation. I add a onclick handler on the shape but the line is very thin and hard to click. I've heard to draw 2 lines 1 with a thicker stroke thickness, but this isn't possible since the drawline method is heavy on the cpu.
View 2 Replies.net - Checking For Null Variable In Workflow 4.0 Transition Condition
Feb 27, 2012I'm implementing a State Machine in WF 4.0. In some transitions, I have added a condition where I check that some variables have the expected values. The variables are enums and booleans, and everything is fine.
However, now I tried to evaluate when a property is null. I have and argument in my workflow, let's say, 'MyArgument'. In a transition, I try to put a condition like 'MyArgument.MyProperty = Nothing'. I never developed in VB.NET, I don't know if I'm missing something here...
VS2010 gives the following error: "Error 4 Compiler error(s) encountered processing expression "MyArg.MyProp = Nothing".
Operator '=' is not defined for types 'XXXX' and 'XXXX'
The type names are exactly the same, and I have debugged VS2010 to ensure that my assembly is not loaded from 2 different locations.
How can I check if the property is null or not?
BTW, I'm using VS2010 SP 1, with .NET Platform Update 1 installed, on W7 64 bits.
Workflow & Change Notification In .NET 2010 Application With Backend SQL Database
Jan 28, 2011I am developing an app that uses a sql backend database (hosted on a different machine).The app I am developing will be run on 10 different workstations simultaneously.Sometimes the app will change the database in such a way that the database needs to initiate a workflow process and I'm not sure of the best way to do this.Also, when database changes happen, how does one best notify the other app instances that the change has happened, so they know to refresh their data? I was thinking that triggers could help initiate the workflow but it might be nice to develop the actual workflow in .net code.Should I write another App to run as a service on the server and do the work and also to tell the client apps when things change?

How To Create Actual 'wizard' That Allows Users To Use It To Create Their Own Forms
Dec 1, 2010I've designed my own encryption application in VB 2008 that has a free tools section where users can choose a particular wizard to use from the drop down. The javascript wizards display the code required to put in their own sites. I already created wizards that users can well, use.I see people have their own "contact form wizards" on their websites all the time. Where users can use the wizard and get the displayed code to copy and paste on their sites. But trying to locate source codes to these things is very aggravating on the web.So what I want to do is create my own "form wizard" like out of javascript, that allows the user to put in some information then get the displayed code to put in their own websites. I'm not looking for the generator such as the online form generators.But the javascript source code(s) for the generator itself.Then I could simply put a form generator inside of my VB-app, that will allow the user to use the wizard, then get the html code to paste in their own sites. Preferably not the PHP one because the php backend is very difficult to put in a VB app.I know that it can be done. For example copying a web pages source code then putting it inside a string, then calling that string from a button click that will open the javascript page in the webbrowser inside the VB app.

View 2 RepliesSQL Data Access: VB2008 / VB2010 - WinForms - Create A Datasourse And Drag / Drop Fields Or Tables On A Form To Create A Grid
Oct 22, 2010I have used VB (versions 2 - 6) through many years; however, I am crash-course training myself into the VB2008 / VB2010 world kicking a screaming. I would like suggestions as to what SQL database access method should I focus more on in my learning process without making me feel that I'm a million years behind. I know I have WinForms where I can create a datasourse and drag / drop fields or tables on a form to create a grid (not really what I'm looking for).
My trouble isn't so much designing the form but in how I access the database. Theres XML, LINQ to SQL, ADO.NET, and many other methods. Not only do I need to grasp these methods quickly but I also need to know what type of projects I should create. What I mean is...I was thinking that I would design a WinForm app; however, I see that there are WPF apps and others to chose from. This is getting deep. I know it depends on the project that I'm working on. My plans are to write an app based off of either an SQL Express 2008 or SQL Server 2008 database. This first app will be standalone for now but may later become multi-user. I know I'm far behind on my learning curve coming from VB6. I have read a bit on VB2005 / 2008 / 2010. I own
both VB2008 and VB2010. I use VB2008 at work. I know ADO.NET is still alive but by what I read online, it's a dying method and is only kept for backward compatibility. XML and LINQ to SQL and other methods are all pretty new to me.

View 2 Replies.net - Given A Large Number Of Objects, Create Multiple Forms In Designer For Them Or Use Code To Create The Forms?
Dec 29, 2010If I have a large number of classes, each similar to the other in certain aspects (they all share a common base class, but each does things differently), and I need to create Windows forms for each to allow easy changing of their values through a GUI? Create one matching form for each object in VS' forms designer, Or Use code to create the forms dynamically at runtime.
#2 makes the most sense to me, because a lot of these objects will share very common features of the form, notably "Ok" and "Cancel" buttons. But one object might need to draw a textbox on the form while another might need to draw a combobox. Not to mention, if I want to put icons on the "Ok" and "Cancel" buttons, I'd have to do this for each copy of the form in designer, and that sounds like it could get out of hand quickly.But is drawing forms through code sane? VS' forms designer is pretty sophisticated and designed to make life easier. Am I wise to consider ignoring its functionality and diving into the trench warfare of forms design through code? Or are there examples of automating form creation based on an existing object's properties?
