Combo Box Complex Binding

Jun 10, 2010

I am having a problem setting up my combo box to pull its menu from a SQL Server table and store to the main data table.Currently my drop down list displays correctly but saves 'System.Data.DataRowView' to the data table. My main data table is called 'Survey' with staffname as a column, then I have another menu table of staff member names which populates the drop down menu.I found that when I remove the DataSource and populate the Items collection instead the combo box saves the correct value as expected but when I use the datasource it saves the words ''System.Data.DataRowView',[code]

In my spare time i give myself programming stuff to do. Today i want to write a function that goes through a string, if the string contains any numeric value the function must return false, if the string has any special characters it must also return false else return true. For example the following strings would return as follows:

String Return Value
Travis True

Complex Types In SOAP With VB 6.0

Sep 15, 2009

I am currently working on a project, which purpose is to call a webservice through a VB script. VB is by far not my first language and I simply reach the point where I do not know how to go on from here.

I have a Webservice descriped in a WSDL document that defines a service that takes a complex type as parameter and returns such one as answer.

The complex type is basically just a string that is wrapped inside a class object. So what i did was to create a new class module and added a public variable to it. I created a new instance of this class, gave it for the purpose of testing a value and tried to call the webservice. Everything goes well untill i reach the call to the webservice, where the program throws an exception that says:

"Class does not support automation or does not support expected interface"

My first thought was that the initialization of the object might have gone wrong but i am quite able to set and get the values on it. So i have to assume that the object is okay. I know that the url to the WSDL document is correct, due to the fact that I can call the document via the browser and it will throw an exception of "wrong type" when i feed the soap method with a primitive.

With out luck I browsed several pages on the net to find a clue what this could. So now i wanted to give this forum a shot.

You should know that i am not able to alter the WSDL file. I have to go with the way it is. In addition am supposed to stick to VB 6.0.

I used a Form in VB to make the call to the webservice.

Here is the call procedure:

Private Sub Command1_Click()
On Error GoTo ErrorHandler
Dim tS

ModelBinding Complex Objects In .net

Feb 8, 2011

I have a custom modelbinder built to handle my accountRequest class.This class consists of some boolean values and a UserViewModel.The UserView Model is made up of strings such as Firstname, Last Name, Address.Originally I was just passing the UserViewModel as the action parameter but I now I need to package UserViewModel inside of accountRequest.however, now my modelbinder will not map the strings in the httpContext.Request to my UserViewModel inside of AccountRequest. All of the booleans map just fine.Is there an easy way to get his data to map to the UserViewModel properties other than hardcoding it? [code]

My.settings Complex Object Is Nothing

Mar 26, 2010

I'm trying to save some settings in a complex object. If I make a dll of the class I can then add it in the projects properties settings list as that type.When the program runs though it won't show up as anything other than nothing. I read you have to have a sub new empty constructor which I have but don't know why else this would fail.First question is how to you do this. Second is there anyway to use a class inside the project as the target of the settings type or do you have to bring a in an external dll to do this every time? [code]

A Complex Question Regarding The REGION Of A CONTROL.?

Feb 26, 2012

Imagine you want to draw a regular shape such as a triangle, rectangle ... all the way up to say a 10 sided figure ( a decagon ) or more. I know that when we try lots of sides it looks closer and closer to a circle or an ellipse. The problem I am thinking of is placing smaller circles ( or ellipses ) at the correct positions near the points of that shape as shown for a triangle below.Here comes the question(s) How could we: a) Correctly place the circles ( or ellipses ) at the points so that the sides are at a tangent to them andb) Can we combine the REGIONs of these to produce a figure with rounded points so the light blue bits get excluded? I guess that to produce a method to deal with all the mathematics involved would be quite a complex task.Has anyway previously tackled doing this or know of any .Net tools I could use for this problem?

C# - Best Practice For Complex Shared / Static Members

Sep 7, 2011

I took over an ASP.NET application and have found this throughout several classes in the application. The programmers before defined several shared/static variables that act as "complex enums" throughout the application. As a fairly new programmer, it doesn't look like best practice.

Here is an example:
Public Shared SecureCommentsWrite As New Task("Secure Comments Write")
Public Shared SecureCommentsRead As New Task("Secure Comments Read")
Public Shared EditEmergencyContact As New Task("Edit Emergency Contact")
Public Shared DisplayPersonalReferences As New Task("Display Personal References")
Public Shared EditPersonalReferences As New Task("Edit Personal References")

The constructor takes the description, then loads the ID key from the database using a stored procedure (the database is SQL Server.) This seems like a good idea since we deploy this application to multiple databases and want to ensure that we load the ID key that's in that database in case it changes. However, since there are literally hundreds of these in the application, the first load takes a while.

C# - Common Way To Test Complex Functions With NUnit?

is there a common way to test complex functions with several parameters with NUnit? I think it is very hard or impossible to test every condition.

I'm afraid the combination of parameters that isn't expected in the function is also not expected in the test.

So the expected condition will not fail but the unexpected.

Now I want to extract B AND D out of this using regex because it is the first parameter and it has no quotes around it in both the overloaded version of the functions. Secondly because MVAL function is an overloaded function with two versions like MVAL("A") and MVAL(B,"01-01-1900") how will I find which version of the function is being used.

I'm using System.Text.RegularExpressions.Regex method.

Complex SQL Table Names In Access Database?

Sep 8, 2010

I am using OledDb to create/retrieve/delete data from Access databases. At one point in the solution, I the user adds data to a new table and the table name is defined by the user. The obvious problem with this is that the user could add spaces, characters, and Access/SQL keywords that are not allowed in the table name. Later in the solution, the user should be able to identify their saved table and retrieve it. I have considered the brute force method of formatting the input to remove offending characters and then reformat for the user's view, but that seems like something I would like to avoid. I have also considered placing restrictions on the textbox with masks, key event restrictions, and checks for conflicts with keywords, but I would also like to avoid that. So, my question is, does anyone have a creative solution for identifying a table name with something like 'my name is table number *1'?

Structure/component For Performing Complex Calculations?

May 24, 2010

I hope this is the right forum. I've been developing something for a while now, and I've hit some walls with the direction I was going. I'm not an expert in .Net, so I was hoping maybe there's a nice solution that I had no idea of its existance.

A little bit of background: I'm building a relatively large scale calculation component which used to be in a spreadsheet. It composes of about 1300 values, about 150 which are passed in to the component, and the remaining 1150 are calculated based on these inputs. However, these values can be in multiple rows, as in there will be multiple rows of these 1300 values. Aggregate calculations need to be performed on these rows on a regular basis. Right now I'm using a dataset to perform this since it supports multi-row calculations nicely, but it has its limitations. It doesn't support some of the mathematical functions that I need it to perform (such as exponential) and performing a calculation like a weighted average is a hassle because you need to add a new field for it. Furthermore it doesn't let you use custom variables in your expressions, so if you want to create an on/off switch for something you need to create a single row table and set up a relationship to it. Also I'm getting tired of the dataset designer being riddled with bugs, and it's obvious to me that it was not meant for calculations of this magnitude. Not being able to see the data type of the field in the designer is a minus too (you have to bring up the property window on that field). I looked in to just creating classes to perform this, but the problem is that it needs to be relatively dynamic, and the calculations need to refresh based on user inputs. The best way I can think of doing this is setting up the 1150 calculated variables as properties so that they will be calculated automatically. But, I'm afraid that this is going to fire off thousands of calculations each time any variable is accessed, which is going to be a rather significant performance hit.

So, my question is whether anyone knows of a good structure or component that I could use to achieve my goals. I apologize if I didn't do a very good job explaining my situation, so I'll try to elaborate on any of my explanations if anything is unclear.

VS 2008 : Randomize Dictionary Of Complex Types?

Jun 29, 2009

I wrote the following function to randomize a dictionary object:

Friend Function RandomizeDictionary(Of T)(ByVal oCollection As Dictionary(Of String, T)) As Dictionary(Of String, T)
Try
Dim oResult As Dictionary(Of String, T) = Nothing

[code]....

This code works fine on simple dictionary objects, but when I use it with complex types I get a type cast exception. For example, I have an object X that Inherits Dictionary (Of String, Class Y). If I call the randomize function on object X, I get the type cast exception. I don't really understand why it cares what the type of the dictionary value is, I thought that was the point of using generics.

In summary the following all work:

Dim x as New Dictionary (Of String, String)
Dim x as New Dictionary (Of String, Boolean)
Dim x as New Dictionary (Of String, Integer)

This does not:

Dim x as New Class X
Class X Inherits Dictionary (Of String, Class Y)
