Program Button To Access Serial Port

Nov 20, 2011

I have very limited knowledge of any programming and am desperately trying to learn. I am attempting to use Visual Basic to create a simple program to operate our church's projector from the computer. I am able to control the projector using hyperterminal and accessing the serial port. I am wondering how I would code a button to send the correct signal to the correct port? I have a simple setup w/ my church logo in background with three buttons. There is an On, Off and Freeze button. I am simply needing to know how to program the buttons to access the serial ports. I hope I am being clear.

Communications :: .net MSComm Port USB 4 Port Relay?

Oct 20, 2011

I am trying to get my 4 port USB relay board to work in VB.net using the COM PORT. I found some code from a poster who has the 16 port USB relay version. When trying his code i can only get it to turn on relays 1-3 all at the same time. The product can be found here: USB 4 port relay

"01+//" - Relay 1 is switched ON
"01-//" - Relay 1 is switched OFF
"02+//" - Relay 2 is switched ON
"02-//" - Relay 2 is switched OFF

[code].....

So i am confused as to how to separate each relay out with that code above and just be able to turn on any number 1-4 relay on or off independently from each other!

Office Automation :: Controlling Access 2003 From 2005 - Error Occurs When - Access Any Property Of "access.Forms("frmTest")"

Jul 17, 2009

I have a program in VB.NET 2005. At some point I have to open an Access2003-Application for getting data in it. I do that by pretending my program is a human user and let it do all the work in Access as a human user would do. Filling Fields, pressing buttons etc. I use the Primary Interop Assemblies for that. So far so good. That code is in use for over half a year now. In the last week I got Office 2007 installed on my machine. Of course I tested the installed version of my program if everthing still works. Every test was succesfull. But if I do the same tests in Visual Studio it always crashes.

All I get is this Errormessage: {"Das COM-Objekt des Typs "Microsoft.Office.Interop.Access.FormClass" kann nicht in den Schnittstellentyp "Microsoft.Office.Interop.Access._Form3" umgewandelt werden. Dieser Vorgang konnte nicht durchgefhrt werden, da der QueryInterface-Aufruf an die COM-Komponente fr die Schnittstelle mit der IID "{66B22FB4-F70E-4F03-A00A-F76E9ADBBF10}" aufgrund des folgenden Fehlers nicht durchgefhrt werden konnte: Schnittstelle nicht untersttzt (Ausnahme von HRESULT: 0x80004002 (E_NOINTERFACE))."}

For all who can't read german:

"Microsoft.Office.Interop.Access.FormClass" can't be converted in to "Microsoft.Office.Interop.Access._Form3" ... Interface is not supported.

Code I use:

Dim access As Microsoft.Office.Interop.Access.Application = Nothing
.
.
.
access = New Microsoft.Office.Interop.Access.Application()

[CODE]...

The Error occurs when I try to access any property of "access.Forms("frmTest")"
