Writing To The Imported Datasource ONLY?
Jun 15, 2010
I have a MS Access database file that I imported into my project as a data source. It's visible in my solution explorer.I have a DataGridView in my form whose data source is set to that imported access file.Right now I have con set to the actual file access database file, but when Iend queries, the changes are made to my actual access file, and not the data source within my project!Dim con as OleDbConnection = new OleDbConnection("***database.mdb")Within the above *** string it points to the databasefile located on my hard drive that I imported into my project. But when I send queries to my DataGridView it makes those changes on the file, not on the data source that I bound to the DGV.

I am using Visual Studio 2008 and created an ASP.NET 3.5 project and solution. I added another project to my solution, a class library. I added a reference to my class library. Now when I click on the properties of my class library, the Default Namespace is set to "HRCommon", which is correct. Now for some reason, from my ASP.NET application, it's automatically importing the HRCommon namespace. So when I want to reference a class out of my class library, I just need to type the classname. I want to have to specify the whole name, like HRCommon.<ClassName> instead of just <ClassName>.

VB has a feature that C# does not, imported namespaces at a project level (My Project>References>Imported Namespaces). When new people check projects out of source control none of our custom imports are included. Where is this VB specific Imported Namespaces stored?

I made a custom control that is a 15x15 grid designed to show a tiled map. Inside I have a class that inherits from pictureBox. The problem comes when I try to place my DLL inside the toolbox. When I click "browse" and select my DLL to import it simply import my class inheriting pictureBox instead of the whole package.
Here is a picture of my files. Grid.vb is the control, clsTile is the pictureBox class and the other one is irrelevant. [URL]

I Imported 2 programs that I made into one solution. I made a "BIG" main menu (new windows form), put two buttons. I code one button to open up the first project (that works fine). I code the other button to open the project I imported, however it says that the name is not declared. Am I doing something wrong?
here is my code for the "BIG" main menu:
[Code]...
now only the "Original name of first project" appears to be not declared, if I delete "Original name of first project", then "the project I imported"is not declared and so forth. Note: These are not the exact names I called my forms. I'm just trying to explain it clearer.

I am use to VB.NET. The game source code I am learning from is written in C#. I find it annoying that I have to add using System.Diagnostics to the source code in order to type Debug.WriteLine.... I checked under project properties, but I cannot find the References tab that allows me to add namespaces to Imported Namespaces. Where do I find this in C#?

I am working on a program where I need a small database. I wanted to use XML to store the data, so I followed this tutorial:Everything there works fine. What I now want to do is figure out how to execute SQL statements against the imported data to do inserts and queries.I've searched and searched, but cannot seem to find relevant info. Every example I see needs a connection string, but that doesn't apply here as far as I can tell.

I have this code that will import the excel sheet to the datatable then inserts it in the database, but I have this problem.I have set the HDR to yes so that the first row will be considered as its header, but the problem now is that if the first row is null, the datatable will automatically named it's header as f1,f2 and so on. how can I set the header as null if the first row is null? so I can validate it afterwards

I've created a project which references some other projects in my solution. I've added the references properly to my project (which I've done a thousand times before), and used them in an Imports statement. I can successfully create references to the objects contained in the referenced namespace at design-time but whenever I attempt to build or run the project, I get build errors saying that the referenced projects do not exist. Their Imports statements change to the broken green underline and the only way to remedy the problem is to re-add the references in my project's properties.
I know that the referenced projects are valid, will compile etc... because they work fine for other projects in the solution. Also, I can go to the definition of their objects as long as I don't build/run.

I'm using a DLL in my program that is free to use in non commercial environments and it generates a dialog box every time I debug my program to remind you that it's not free for commercial use etc.. At first I couldn't care less about the popup dialog box but when your programming all day it gets really annoying. is there a way to suppress those popup dialog boxes or do I just need to go to my happy place and ignore them when they pop up?

I have a project solution which consists of few projects including a project which for window controls. In project A, I can import the project control but for another project B, I can't import the project control and cannot access the contains for the project control. May I know why and how to check whether the project control can be imported or not? If the project control is not importable to other project, then why my project A can import that and project B is not able to import that?

Another noob question from me...one of these days I'll get the hang of this VB!I am importing data from an Access table that has four columns/fields. I have set up the relevant headings etc on the list view control...but I have also set up a 5th column as I want to have that representing the percentage change between columns 3 and 4 (which are numeric).
Here's my code. What I want to know, is that having confused myself with code I've written / adapted from advice given etc where do I put in a forumula to add something to a column in my list view that is a calculation based on two columns imported from the table?

Enviro: 2007 Exchange Server, 2 Intranet servers (1 deploy, 1 dev) running .NET 2.0 app - all within same network / behind firewall. I am working on a legacy app by our previous web guy, when our sysadmin upgraded to exchange 2007 and put it on a new server all of the mail functions in old app broke. Had to upgrade to .NET 2.0 (from 1.x) and nothing worked untill I tried new SMTP code in a local function in the codebehind of a page of the app instead of calling a class, as follows:
Function SendNow(ByVal strFrom As String, ByVal strTo As String, ByVal strSubject As String, ByVal strBody As String) As Object
Dim msg As New MailMessage()
Dim smtp As SmtpClient
[code]....
So the above works fine, in that file. The problem is that the app was designed to call a class that resides on the dev server. When I move this same code into the class on the dev server I get transport errors. I think this has to do with the fact that we're using integrated authentication with impersonation=true and it seems to get dropped due to the class being on a different server (even though it's behind our firewall).
I could either try moving the classes to the production server or somehow keep the authentication in the class working through the hops. Either way I need to keep the class because it's referenced all over the place (in more than just this app). I am not that savvy in .NET and I cannot figure out where the setting is within the app that defines where the class is imported from. It just seems to be available no matter where the app is deployed. (Working files are on same server as classes, then publish the app to production server).

Below code is supposed to update a table in oracle with rows imported. But it seems to update all columns in the table with only the first column which is imported from the CSV file. I figure its the "ReadFields" property which needs to manipulated/changed.

We've just re-targeted a VB.NET project from .Net 2.0 to 3.5.Various framework types are now missing from our project. Wherever the type is referenced using a fully qualified namespace it's missing. If the relevant namespace is imported for the type; it's found.For example,this doesn't find the type Object, with compiler error "System.Object is not defined.":

I have imported a number of web elements that are called "reference values" from a website. These are added to the end of a website to navigate to a corresponding page. I am going to go to said website individually for each "reference value" and scrape code for use in a scheduling programming. How should i navigate to each of these websites when the url cannot be edited. The "reference values" are currently stored in an array but this does not seem like the correct method.
