View 1 RepliesAccessing Documents From SQL Server Database?
Feb 15, 2009I have saved documents into my SQL Server 2005 database and they have been converted to bytes. My web page is made with VB.NET in Visual Studio 2008 with ASP.NET. The following is exactly what I need to achieve;
1. Allow user select document with a button
2. Select the document from the SQL Server table
3. Allow the user to download this document.
The error I am getting is that Category is set as Byte and it can't be passed through GetDocument because filePath is a String. I think that I am pulling the file path from the database wrong
[Dim Category As Byte() = NothingDim fs As FileStreamDim br As BinaryReaderDim document As Byte()Dim documentFilePath As String

Jul 13, 2009I found an example of a simple irc client, but I'm really confused about how it sends data back to the irc server. In the example, this is the code used to respond to the server's PING request. it lies in the onDataArrival event of a sockets client:[Code]
However with this simplified code, as soon as it tries to respond to the PING request it is disconnected from the irc server with the reason "Excess Flood". So I was hoping someone could explain to me the difference between the pretty complicated method and my simplified one which doesn't work.

Disconnected And Connected Feature Of ADO.NET
May 19, 2010I just read a book : Pro ADO.NET 2.0.It discuss about the disconnected and connected feature of the ADO.NET.In disconnected, the "data container" is DataSet.But it doesn't say anything about the data container if i use the connected feature. In ADO, we have recordset, what about ADO.NET.
View 3 RepliesHandle When COM Object Is Disconnected From RCW?
Feb 15, 2012Is there any way to run code when COM object is about to be disconnected from RCW without implementing IDisposale interface and explicit call MyObject.Dispose in client code?
The code below is not working. When program enters Finalize sub, ExcelApplication is already disconnected from RCW, and I get error. I understand why it happens, but I want to get a solution.
I want to make it working the following way: when last managed reference is released, code from Finalize sub is executed before COM object is disconnected.
My question is - is it possible at all and if it is then how can I handle this event inside the class, without need to call Finalize explicitly from outside?
Very simple class:

Dim ExcelApplication As Excel.Application

View 2 RepliesC# - Deploying App To Production Using Debug Mode Rather Than Release Mode?
Oct 28, 2010I work for a shop that maintains a fairly new app. The app still has its fair share of bugs, with numerous tickets coming in daily. The error information we're given with those tickets is not as useful as it might be because the application was compiled in Release mode, which I read is smaller and faster (makes sense).
Are there any ramifications to deploying a .NET application to production that was compiled in Debug mode? I would expect it would be a bit slower, but I've read the difference is nominal. This would assure us that when we get errors on tickets we have line number associated with those errors and this, of course, makes debugging much easier. major red flags that would prevent you from doing this? I'm tasked with researching the possibility.

View 2 RepliesNetwork Connections Disconnected After Launching .NET App?
Feb 17, 2011I shipped a VB .NET app to my customer. They installed the app in program files folder. The app starts and everything works ok. Now my customer reports that some intranet TCP/IP connections are interrupted after starting the app. Sometimes they are not available after starting my app, sometimes the intranet connections are still available after my app has been started. After my app has been started, there are connection error messages to their intranet services. After re-starting the machine, they still can't connect to the intranet services. A fix is to login with another user name or re-load the profile from the server after they have been logged in on another machine.
Do you have any ideas where to start further investigations? Is it possible that my .NET app interrupts or blocks intranet connections? Could you recommend any trace tool that gives me a hint when and why the intranet connections are blocked? Why could it work for them after they login on another machine?I am wondering if my .NET app could disable the intranet connections. Do you have any recommendation for testing that?

Mar 16, 2010I have written a simple VB.NET program that connects to a MS Access Database. This program runs in Windows 7 XP Mode, but does not run properly in straight Windows 7. Somehow, the Windows 7 does not connect properly or read the MS Access database data properly with the DataAdapter.Fill method. I have dual monitors, so I can run the identical program side by side (one in Windows 7 and the other in XP Mode) - one works and the other doesn't (it doesn't crash, it just get "nothing" from the database when accessing - acts like it's not connected). Has anyone else run into this, or similar, problem with VB.NET and MS Access connectivity?
View 14 RepliesAccessing A Database With A Datatable?
Mar 18, 2010I am currently working on a project for school. I have the project all laid out in my mind and everything but there is one thing that stops me. I can not access the data from the database itself ...
(detailed info)
I am using an AMD Athlon x64 bit processor with a windows vista 64 bit operating system. I am writing the program on visual basic 2008 express edition. When I open up the visual basic 2008 express edition and create a new project the first thing I do is go to the view menu and activate my database explorer. I connect to the database in question through the database explorer. The database I am connecting to is an access 2007 database (ive opened up the access 2007 files and they do open and display information properly, in otherwords, they do work) I then put in a listbox and use the following lines of code in a form load event to both A) create the datatable and B) automatically fill the listbox with the database info.
Dim dt As New DataTable()
Dim connStr As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=MEGACITIES.MDB"
[Code]....
When I test the program the listbox does not fill up with any information from the MEGACITIES access 2007 database. Ive tried connecting to the database by establishing a connection through the datasources window. Ive tried establishing a connection to the database through both the database explorer and data sources window. No matter what I try I can not get that information accessed.
Im almost confident that this has to do with my processor being 64 bit.
