Build Error - Cannot Find Wrapper Assembly For Type Library
Oct 20, 2010A co-worker checked a very simple Visual Basic Visual Studio 2010 application into our version control system. When I checked it out and tried to build it I got the weird error below, which I am guessing has something to do with which .Net Framework the build is targetted towards and also which Framework I have installed.

How To Work With Predicate And .Find Methode
Jan 4, 2010I have no chance to simple search a property in my property list by using the ".Title" of the property. Instead of using "For each > If .Title = SearchTitle" I prefer to do it with the Predicate and ".Find" methode.
Can someone help me to find out, how to avoid using the local variable " _SearchProperty" in the example below?

Pass Additional Parameters To Predicate?
Aug 20, 2010My issue is to Find exact one Calendar object from a List Of(Calendar) by passing a particular date. I got to know about the predicate but not sure about passing parameter to it.

I got the predicate samples from Google and reached till now. But not sure how to pass my parameter i.e. date to it.

List.Find. Pass Values To Predicate?
Apr 16, 2010Having a bit of trouble using the List.Find with a custom predicate i have a function that does this
[code]...
by doing it this way means i have to have a shared "currentKey" object in the class, and i know there has to be a way to pass in the values i'm interested in of CurrentKey (namely, keyname, and oldkey) ideally i'd like to call it by something like keys.Find(AddressOf FindByOldKeyAndName(Name,OldVal))however when i do this i get compiler errors.How do i call this method and pass in the values?
Loading Record By Predicate / Lambda Via LINQ
Jan 12, 2011I am pretty confused about lambdas. What I am trying to do here is write a function that will return an object from a certain table with a certain criteria. So lets say I can write:
function GetRecord(TableName as string,Criteria as string) as object
'do the linq-stuff
end function
Now I don't care if the parameters are strings or lambdas or whatever, but the end result must be that at runtime I don't know which table and which criteria will be used. As sometimes I need to get a customer record by email and sometimes a product by id etc. If possible I would prefer returning a list of matching objects and then I would just use .firstordefault when I want 1 (such as by id...).
Reading RDF - Data Is Stored In Triples: Subject, Predicate, Object?
Feb 17, 2010After browsing the internet on how to read RDF Triples, the only things i came up with were user created libraries and so on. Some MSDN documentation on Microsoft's website confused me as well, as trying to import the Namespace shown was not possible. (Maybe it's possible just in C#? no idea).So how would someone read an RDF Triple using VB.NET? RDF is an XML format in which data is stored in triples: subject, predicate, object.
Example:
<rdf:RDF

Sep 12, 2011I'm trying to add a control on my form and each time an error pops up : "Failed to import the ActiveX control. Please ensure it is properly registered". I'm currently upgrading from VB6 to VB.NET (VB2010 running on Win 7).I installed vb6 on my win 7 PC and i can still add that control on any form - so definitely the OCX is properly registered. My guess here is that VB.NET is unable to create a COM wrapper for that OCX.

View 2 RepliesCreate A .exe Wrapper For A Flash Player?
Feb 9, 2010I would like to create a .exe wrapper for a Flash Player using VB.NET. I am having a few problems.1.I seem to remember being able to import Flash Player as a control into Visual Studio (2008 Pro). For some reason, I can't seem to VS to import it anymore. (I tried using the OCX from Visual Studio) Perhaps I'm looking for the wrong file. What file am I looking for?
2.Is including Flash inside of a VB program legal?
3.When a control is included in a VB.NET program (such as Flash) does the control need to be distributed in a separate file, or will the compiled application contain it in the ".exe"?
I was able to import the control as the Flash10b.ocx from c:WindowsSystem32Macromed directory as a COM component. Question 2 and 3 still remain.Is there documentation on the ActiveX control? I am trying top figure out the API for ExternalInterface.

View 3 RepliesRead-Only Wrapper For Customized List
Dec 7, 2009I have created a customized list (by implementing IList) where I added a few special methods. Sometimes (but not always), I only want to expose this list as read-only. To do this for normal lists, I use the Collections.ObjectModel.ReadOnlyCollection wrapper, which works fine typically. But it seems by passing my customized list through this wrapper, my added methods are no longer visible, which defeats the whole purpose of having this customized list object in the first place. How can I create a read-only version of a customized list?

Building A ASP.NET Profile Wrapper To Use With An ObjectDataSource Control?
Dec 26, 2011building a ASP.NET profile wrapper to use with an ObjectDataSource control. I would like to have the serialized profile data that I have defined in web.config be accessible via a FormView control within a user control. I'd like the users to be able to view and update their profile data. I have part of the code but am lacking the experience to complete it. I'm using a aspx page with some text boxes and having users update via a simple form now but I need something more reusable and efficient, not to mention moving the logic to a middle tier. I see that the ObjectDataSource control has some intrinsic ability to view profile common data but that seems to be limited.

View 4 RepliesPut A Wrapper Around Some Functionality That Uses A Web Service To Return Some Information?
Nov 28, 2011This is annoying. I'm trying to put a wrapper around some functionality that uses a web service to return some information. The intention is to wrap all of that communication into a dll such that the user can simply call functions from the dll to get back information, without needing to care about the service.As far as I can tell, that isn't possible, because the service information, as far as bindings and endpoints, HAS to exist in the app.config of the program that references the dll. That means that anybody using this dll won't just be able to add a reference to it and use it, like they would with any other kind of dll, they must also edit their app.config to add in a bunch of information. That's a simple copy and paste job, but it's incredibly unfriendly, and exposes some of the internal workings of the dll to casual inspection.
View 8 RepliesVB6 Conversion To Wrapper To Prevent Null Exceptions
Sep 14, 2010We are converting a large VB6 application to VB.net. The problem we have all over the code is the .NET converter did not "reorder" the "IF" and other statements in the code to stop execution when a DBNull value exists. For example, we have code like this all over the place.
"If rRow.Item("av_election_id") > 0 And (rRow.Item("Challenged") <> "SUSPD" Or IsDBNull(rRow.Item("Challenged"))) Then"
This causes a error when "rRow.Item("Challenged") is dbnull
The line of code below corrects this issue but we have thousands of lines of code to reorder and refactor.
If
dtAVVoterRow.Rows(0)("av_election_id") > 0
And (IsDBNull(dtAVVoterRow.Rows(0)("Challenged"))
OrElse dtAVVoterRow.Rows(0)("Challenged")
<> "SUSPD")
Then
creating a wrapper class or something to allow us to keep the first example of code above where it will not throw an error when encountering a Null value? I don't know if a wrapper that reordered the If statements, or captures the error but continues the execution somehow?

I am first doing a simple join between TW_Sites and TW_Investigators. Then there are two sub-tables that are involved. TW_InvestigatorToArea and TW_InvestigatorToDisease. While most of the where clauses are working fine, I have found a performance issue that won't be an issue right now, but will be an issue as the table gets bigger.
The arrays DiseaseCategories and DiseaseAreas would be the results of a CheckBoxList result.
