VS 2008 - Add Microsoft ActiveX Data Objects 2.5 Library From COM References - Dim Con As New ADODB.Connection
Sep 2, 2010
I am having problem with Visual Studio 2008.... When i add the Microsoft ActiveX Data Objects 2.5 Library from COM References, and just run the blank form, it runs perfectly.... But whenever i declare anything related to ADODB like dim con as new ADODB.Connection, then after that it gives me error and doesnt run the project. A first chance exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll. After that if i comment that like (declaration), then error goes........ I tried uninstalling each and every component and VS as well but the error doesnt goes....i am using Windows 7 x64. The same is working in Windows XP x86 in my virtual machine..... as i am not able to start my project

I used the tool about 3 years ago to create the classes for a webservice client to send or recieve arrays as complex data. Now i have to update these classes, since there are additional informations, that have to be exchanged. When i use the tool now with the new wsdl-files, it does'nt create the classes for complex data (structur, IGCTMObjectFactory), but only one class for simple data. In addition i have to establish a new client, that sends an array of complex data and receives another array of complex data. I tried to build the classes manually combining the client that sends an array with the client, that receives an array, but I failed.

I have upgraded my VB app from VB to VB.NET and its working fine. Now, I want to convert my existing DB connection strings from ADODB to ADO.NET so that I dont have to use MS Access on every client which runs this app. Currently the VB app looks up into an Access db to get the server ip, username, password etc. I aim to hardcode these values so that I wouldn't need the Access db anymore. Any inputs on how this could be done?

I'm still new to most of this but I seem to be finding that while you can load the Microsoft Reference Libraries at no charge, I'm told they are the slowest method to use.I have tested Gembox and only read about others. Is it worth the effort to deploy these 3rd party platforms, even if I'm working with small data sets, for the moment at least? Speed is one thing but when you're talking about 2 seconds vs 0.2 seconds, it's not worth $900 per seat.
Are there other 3rd party references which are Open Source, or no cost, etc...I would like to hear what the rest of us are doing on this?

I've been passed a solution that has a vb.Net 2.0 project that references to a .Net 3.5 library. The library compiles with out problem but the vb project does not. It complains of missing objects which are in the library which are correctly added in the imports. Also I see a yellow yield sign next to the reference library also when I add the reference it complains of the framework version difference. Any help is apritiated. Also I'm using VS10. Imported the projects with no errors. A colleague has this working on VS9.

I am building a VB 2008 Express Edition application.I have built a database (with a single table) using SQL Server Compact 3.5 and have connected it to the project. I am able to view and edit the data using a DataGridView on a second form (tutorial made this very easy). I need to work with the data in the table within the application. how to easily load the entire table into an array or even read the table a row or cell at a time so that I can make all of the data available for manipulation within the application (the tutorials only seem to show how to display the data).

I am developing an application with Visual Basic 2008 Express Edition and using the Microsoft SQL Server 2008. I have tried to connect the application to the server and database but I couldn't.I have found the following connection string:[code...]
I really do not know where to put this connection string and how to get its details such as SERVER_NAME_OR_IP_ADDR. I am also using SAVE and SEARCH buttons to save the input form to the database search using SQL queries. Do I have to use a separate function for this string or put it every time I need to connect to the database?

I am working on a project. Part of my project requires me to capture data, for example, email address, from certain rows/columns of a datagridview(form2.vb) and displays them in a textbox on another windows form(form1.vb) with a click of a button(Add Contact button). The problem is the datagridview on my form must be able to display databases by making a connection to Microsoft SQL Server 2005 but so far, i have not been able to do that. I have seen many codes with regards to my problem but i do not know how to implement it.
Below are my codes that i have written so far. My program's limitations are not being able to display databases from Microsoft SQL Server 2005 so i created the statement below to add columns and test my codes.
DataGridView1.Columns.Add("CustName", "CustName")
DataGridView1.Columns.Add("Email", "Email")

I have a button which opens FormTest. When FormTest opens, it creates an instance of ClassTest and that class instance takes the form instance that called it (FormTest) so that it can perform operations on FormTest from the ClassTest class instance. So i have a form which owns an instance of a class which has a reference to the form.

So I've created a series of objects that interact with a piece of hardware over a serial port. There is a thread running monitoring the serial port, and if the state of the hardware changes it updates properties in my objects. I'm using observable collections, and INotifyPropertyChanged.
I've built a UI in WPF and it works great, showing me real time updating when the hardware changes and allows me to send changes to the hardware as well by changing these properties using bindings.
What I'm hoping is that I can run the UI on a different machine than what the hardware is hooked up to without a lot of wiring up of events. Possibly even allow multiple UI's to connect to the same service and interact with this hardware.
So far I understand I'm going to need to create a WCF service. I'm trying to figure out if I'll be able to pass a reference to an object created at the service to the client leaving events intact. So that the UI will really just be bound to a remote object.
Am I moving the right direction with WCF?
Also I see tons of examples for WCF in C#, are there any good practical use examples in VB that might be along the lines of what I'm trying to do?

We have had a visual basic.net (2002) service running on our server for several years now with no problems. However I recently needed to update one of the DB calls by adding additional fields to the SELECT statement. However, after adding the new fields, some of the returned data is coming back empty when I loop through the records. I have confirmed that the querystring is accurate and returns all of the data through a third party viewer, so I'm not sure what is going on.For example, in the code below, everything worked fine with field1, field2, and field3. However, when I add field4, data for field2 and field4 come back empty when looping through the results.

I have vb .net windows form application that I want to connect to Microsoft access database using "Microsoft DAO 3.6 object library". My problem is that when I go to Project tab -> Add reference -> COM tab, there should have been "Microsoft DAO 3.6 Object Library" on the list, but for some reason It's not on the list. Then I googled, and found out that the location of "DAO360.DLL" is "Program FilesCommon FilesMicrosoft SharedDAO". After clicking on Browse tab, I browsed to that location, and I guess I added reference on another way.This is the code that I used before for connecting to Access, but for some reason It doesn't work this way on this PC.

I want to access the methods of a dll that is not managed. Seems to be vb6 from my best guess and what I know about the program.That part I have managed to figure out. If I drag the x.dll to my bin folder, the interpreter wrapper is created, etc. I can access the methods in the dll just fine. The problem is the database connection.
For informational purposes: The dll is compiled for a vbscript .asp website. There are a few methods in the dll that just manipulate the input (which I can access error free- its how I tested the dll usage), but most make a db call to get or set or update, etc. data in the db. The dll expects an ADODB connection. The asp files are setup such as:
set DllObj = server.CreateObject("dll.class")
set connect = server.createobject("ADODB.Connection")
connect.open "SystemDSNName","user","password"
[code].....
It is using a DSN but just as easily could be a DSN-Less connection. My problem is that the dll expects the connection to be open and available to it. Can I make a ADODB database connection available and open for this dll in a vb.net asp.net website.Basically,I need to use the business logic and db data changes through this dll, but want to make the front end in asp.net.I know there is an ADODB namespace in .net somwhere and I tried using it but it was not doing the job and really, I did not quite understand how to.
