Im using Visual Basic Express 2010.This is from a tutorial in Microsoft Visual Basic 2010 Step by Step
I'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?
I'm trying to add the export to word capability to my code and adding the following to my code gets me some warning and errors. I was able to find a download sample code to do this, however it's strange, when I run the downloaded code, it didn't encounter error but I put this together with my code it produced some errors.
Option Explicit On Option Strict On Imports System.IO
Can anyone tell me if the Imports System.IO accepts all files types?? What I mean is, can I use it to access .csv, .xls or .doc files? And one other thing.Do I need to include the file location in the body of the procedure/function??
I'm working on a basic file encryption by using the Imports System.Security.Cryptography.I was thinking of putting a password as a final security measure.Would i have to store the password inside the file or how will this work?
I am currently trying to create a DLL for use with a RESTful api. The only issue I have is that so that this DLL can be used in a service or a program without a GUI, so I can't use "Imports System.Drawing.Imaging" as this requires a form. I have looked around for examples to handle this without using this library but have had no luck.
When trying to compile my newly created ClassLibrary class 'Validator' that validates entries made into TextBoxs or MaskedTextBoxs, I get the following error:
Warning 1 Namespace or type specified in the Imports 'System.Windows.Forms' 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.

Following is the first part of code in the class:

What can I do to resolve this problem? The classes in this class library will be used to validate forms data input in a number of varied projects.

I 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.

This works, but is this possible to set the value with an imports/api call in .Net I found the function GetSystemMetrics but there isn't a SetSystemMetrics and with the SystemParametersInfo you cant change the SM_CYVSCROLL value
I am familiar with c# way of fixing the import via Ctrl-。 but how do you do this for visual basic project?Also does visual basic does not seem to have the [Organize Using] feature for c#.
I 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 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.
I 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.
I 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).
I need to import java.util.zip for my project to zip and unzip chosen files/folders in vb.net. But when i say imports java.util.zip, i get the error "Namespace cannot be found". I went in the add reference and checked in both .net and COM components bout found nothing for java. What dll would i need to make this work?
I'm developing an web application using VB.Net, and I would like to know, if is there any way to make a namespace to be viewed by all project without necessary Imports?
