View 2 RepliesI have a function when fired queries against the database (twice) and returns the results in a dataset. It checks the results (to make sure there are some) then loops through and grabs each row from the returned dataset and imports (copies) it to a different dataset.I also add a primary key into a List so I do not add the same item twice (from the 2nd query) to the dataset.I then return the dataset.The problem? The query works and there is a returned value.. however the dataset in which I aim to import the row(s) to does not keep the imported row.
Public Function GetClientsWithMonitors(ByVal argHost As FOO.Interfaces.BAR) As DataSet
Try
Dim localDataSet As New DataSet()
Dim clientsWithMonitors As New DataSet()

View 1 RepliesI need to have a CSV get sorted alphabetically before/during/after it gets filled to a combo box. What I have is a text file with a list of company codes, and company names in the following format:
companycode,companyname the code below loads the CSV and then fills a combo box with each value. When a user selects the company name from the combo box, the corresponding company code is loaded into a text box and used to upload a file to a sepcific directory based on customer. I've looked at ways of sorting comboboxes, and presorting the CSV before loading, but is there a way to do it during the importing/datafill?

In my Solutions in Visual Studio, I have 3 projects.
- Common (Root namespace: PodcastPlayer.Common)
-PodcastPlayer (Root namespace: PodcastPlayer) This is the Silverlight project.
-PodcastPlayer.Web (Root namespace: PodcastPlayer.Web)
In Common, I have several classes and service references.But my problem is that I can`t not use PodcastPlayer.Common namespace in PodcastPlayer project.
how do you know what imports to add to the top of the page? The only way I have figured it out was to look up other people's code with the methods I am using to see what is used.
View 4 RepliesI have created some code that pulls certain data from sql and saves it as a txt file (columns seperated by commas). I can't seem to find a way to import these newly created txt files into excel. I create 2 txt files, and would like to import the 1st one to sheet and the 2nd one to sheet 2. Then add a row to each sheet and fill in headers.I have the code down, and create the workbook and sheets and adding the rows and headers, but I can't seem to find a way to do an import into excel through the vb.net code.
View 1 RepliesI knew from here that we have to do the explicit imports for child namespace because imports will not include the child namespace.But my question is that if I do "imports System" whether it will include all the classes/methods inside that namespace in the IL/native code or only referred ( used inside the application) will be included in the IL/native code.

I have never used LINQ before, and I am getting an error in an application that does use it. This is a VB.NET (.NET 2.0) project in Visual Studio 2008.
Here is the offending code:
Dim orderedRows = From r In resultRows Order By r.FIELDNAME Select r
And here is the error (names changed to something generic, but otherwise accurate):
Expression of type '1-dimensional array of
Company.OurLibrary.FunctionalArea.Library.StoredProcStuff.USP_MYPROC.ResultRow'
is not queryable. Make sure you are not missing an assembly
reference and/or namespace import for the LINQ provider.
C:projectfilename.vb
So I recognize that I need to import LINQ libraries. This link led me to add "Imports System.Linq" to the file, but that is an unresolved reference. Based on the same link, I figured I needed to add a reference to "System.Core" to my project, but it is not listed as an available option when I try to add a reference (nor is it already checked).
a common VB.NET class should look like the following:
Public Class MyClassName
End Class
Besides, I have already seen, if I remember correctly, all of the import statements visible just like in C#:
Imports System
Imports System.Data
Imports System.Linq
Public Class MyClassName
End Class
How to make these default imports visible by default in VB.NET using Visual Studio 2008?Is there some setting or the like in the options I shall set?

View 12 RepliesI have a generic repository that I communicate with my object context with. My object context has function imports that I want to be able to call through my generic repository. Currently I call them through an "Execute" function, but this is not ideal because I have to pass in my function name and parameters as strings which can cause run-time exceptions. My function imports map to complex types.
Is there a way to do something similar to:
Dim rep As IRepository(Of ComplexType)
Dim type As ComplexType = rep.Find(where:=Function(t) t.FunctionImport(parm, parm)).First()

I have a Web Service Application Project in Visual Studio 2008. This is supposed to be an ASP.Net 2.0 project and at some point this has been rebuilt using 3.5.VS has kindly added in project level imports to System.Linq and System.Xml.Linq, but when I have re-targeted the project at 2.0 these project level imports have remained.Because the Web Service Application Project does not have the detailed window for editing project references I cannot find how to remove these project level imports.There is no .proj file which is where I would assume these were included.I cannot now build the project as it fails, even though I only get warnings (no errors reported) such as this:Namespace or type specified in the project-level Imports 'System.Linq' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases.
View 3 RepliesI'm not sure I understand the point of CompilerParameters.ReferencedAssemblies. I thought they could be used in place of using Imports statements.I'm obviously wrong because even if I set CompilerParameters.ReferencedAssemblies.AddRange( {"System.dll", "Microsoft.VisualBasic.dll"}) I still need to use Imports System and Imports Microsoft.VisualBasic in the script for it to work.
Are the Imports used only so that I can use MsgBox() instead of Microsoft.VisualBasic.MsgBox()?What if my script "Imports Something.OrAnother" from an assembly called Something.OrAnother.dll. Do I need to scan the script looking for all of the Imports statements and then add them (plus ".dll") to the CompilerParameters.ReferencedAssemblies before compiling?
