USB Communications And .net Service Packs
Mar 15, 2009
I have a program to print to receipt printers and communicate with other pos hardware using the esc/pos commands and other pos device structures.It talks happily on LTP ports and COMM ports and for the last 3 years has worked well with USB printers, extracting information from the registry and connecting directly to the USB port.For all communication is uses direct calls to kernel32.dll via the win32api.The difficulty is the latest .net service packs have altered something in the communication. The USB side of the software fails to communicate on computers with .net 2 service pack 1 or above installed.

I need to be able to detect which version of Excel I have installed in my machine from some .NET code I'm developing. I'm currently using Application.Version for that, but it doesn't give me information about Service Packs.

I got a new laptop friday, it has windows 7 and its a 64 bit system. I installed visual studio 08. everything was fine until I opened one of my projects.Seems like the powerpacks drawing items no longer exist, there is only a pointer and reort viewer in the group now and all of the items that I have used in the past are keep my app from running.

I am using VB2008 Express and am curious how to send a command via RS232 communications. The string that I need to send is 02h PON 03h. The start and end bits are 02h and 03h.
How can I convert 02h and 03h to its ascii form. In hyperterminal, I use the sequence {(hold)ALT 0 0 2} on the number pad to send the start bit.
I am using this code currently without the start and end bits

I have used the vb power pack for graphs and the following to files are included in the application files.
Microsoft.VisualBasic.PowerPacks.Vs.dll
System.Windows.Forms.DataVisualization.dll
But the install only works on the machine it was built on, if I take them out it installs but no graphs. How can I get this to install on all machines?

I've just created a setup file for my application . Instead of using the click once process , I used the Create Install Free 4.14.5 program , in order to be able to specify some parameters that under click once I couldn't (like specifying installation folder etc) . The problem , however , is that now when I installed the application , an error message appears saying that the computer is missing the Visual Basic Power Packs 9.0 (which I indeed used in my application) . So , is there any way I can add it to my setup file ? That is in order to avoid making people manually downloading and installing it .

Here is a simple class I coded inheriting SimpleShape in VBPower Packs. The events are not firing. What might be the reason? I checked the property "CanRaiseEvents" and it says "True"

i have a Windows service that is hosting a WCF service through net.tcp and this is working great. I have also created a WCF service application. I am trying to add the net.tcp service reference to the service application. Then I add it to the GAC that goes ok but if I try to RegAsm the WCF service application to allow it to be called from Server.CreateObject I get the error:
Warning: Type library exporter encountered a type that derives from a
generic class and is not marked as
[ClassInterface(ClassInterfaceType.None)]. Class interfaces cannot be
exposed for such types. Consider marking the type with
[ClassInterface(ClassInterfaceType.None)] and exposing an explicit
interface as the default interface to COM using the
ComDefaultInterface attribute.
It does not work. I have tried to call it through a class library but this does not work either as the end point is not set correctly.

I have a VB2008 application which can control a windows service i.e. start, stop, pause etc. This runs ok on a Windows XP machine but not on a Win 7 machine (message is - Service error cannot open <service name> service on computer '.') ( if I stop the UAC then it runs ok ). It seems to be a rights issue,

This is a bit of unusual problem that I'm experiencing, but recently one of the users of a production application started reporting errors in the system. These were traced to a 503 Service Unavailable error when making a call to a web service used by the application.
Now here's the odd part, only the one user is affected by this issue. Other users of the application have not reported any errors. When the user logged on to a different machine that worked for another user, they still received the error.

In the past I had the indexing service installed on a Windows Server 2003 and used it to index files for my website. I did this by executing an OleDbCommand with a query and a connection string.How do I accomplish the same thing with the new "Windows Search Service" (Windows Server 2008) by using VB.NET? Does this work the same way so that I only need to change the Provider name which has been "MSIDXS.1" up to now? Case true, what is the new Provider name?

I'm using Visual Studio 2010 and .NET3.5. I've created a WCF service application. I'm including two DLLs that contain the types I'm returning. The first method I wrote works both in WCF Test Client and also in a console application I created to test. When I move on to the next method that returns a generic list of a type. It works great in WCF Test Client, but when I update the service reference it acts as if the service is unavailable. All my objects say can't find reference, and I can no longer see it in the object browser. It's like it just disappears. I can still see it in the Service Reference folder. If I go back to the WCF app and comment out the contract and implementation of that one method it work again. I created a local class very similar to the class I'm using from the dll, and the it works. Is there something I'm missing here? Can someone point me in the right direction?

When you create a Windows Service, you create a list of the services you want to start. The default is this:
ServicesToRun = New System.ServiceProcess.ServiceBase() {New Service}
Can you have multiple instances of the same Service class (that bind to different addresses or ports), like this?
ServicesToRun = New System.ServiceProcess.ServiceBase() {New Service("Option1"), New Service("Option2")}
Or will that cause problems? Should we use two different classes instead?

We have a server with multiple services written in .Net 1.1 and 3.5 running on a Win 2003 server. Everything runs fine, but when we stop a certain service, an unrelated service stops. I have checked and neither has any dependencies. The service we stop is in 3.5, and the unrelated service that incorrectly stops is in 1.1. We get no error messages, nor event log errors, so we are baffled.Does anyone have an idea as to what may be causing this?

I inherited a working WCF Web Service with one major flaw - the WCF Service consumes memory and does not release unless the service is restarted. After a half a day of requests hitting the web service, the memory on the server hosting the service climbs to close to 2 gig and is dead in the water.
I'd like to be able to release memory after the web service has received its response but cannot figure out how (WCF is still new to me). [code]...
