Did you put this at the top of your code??
Imports System.Io.Ports
And are you using .NET 2.0 (Visual Studio 2005) or greater?
|
|
|
|
|
yes i did.. that's is why i don't understand why the error still appear.
|
|
|
|
|
I'll repeat my question. Are you using .NET 2.0 (Visual Studio 2005) or greater?
|
|
|
|
|
Yes, i am using visual studio 2005.

Well, there's nothing to add a reference to since the SerialPort class is in System.dll.
I have no idea what you're doing wrong. It should be as simple as:
Imports System.Io.Ports
Public Class MyForm
...
Private ComPort As SerialPort = New SerialPort

Well, I would be reading on how to interact with a serial or USB port and looking for hardware that supports those ports and the methods you find. There's at least one article like that on serial ports on CP.

Me.TextBox1.SelectAll()
Me.TextBox1.Copy()

My windows application needs to be able to connect to dbf files. The target computer will be Windows XP and Vista. Microsoft only has ODBC drivers for Windows 2000. Is there an ODBC driver available or better yet, is there a .Net driver that does not use ODBC?
|
|
|
|
|
And you DBF file is what, a DBase file?? What's the database engine that uses your DBF's?? Without knowing that, you're stuck. You have to use either ODBC (not the best choice at all), or OleDb.
|
|
|
|
|
The dbf file is a Visual FoxPro 8.0 file. Is there a OleDb driver or something else available?
|
|
|
|
|
OleDB is about the only thing you've got to use. CHeck out the System.Data.OleDb namespace.

im a beginner at VB.net or something that smell proggraming.. Big Grin
But i wanna learn it. I saw how to make an ultimate player.
It says like this :
(First, you must insert a Media Player Control in your form (Note: If you cannot find the control, look under "Com Components" in the "Choose Toolbox Items" menu). Now the Media Player will have its own controls, so to design your own, you will have to remove these by setting the UiMode to none.)
but i cant find Media Player Control at Com Components in Choose Items.
And i cant find UiMode too.... Frown
Please Help Me!!!

hi all
i want to attach biometric machine with my .net application and wants to make interaction with it.
i want to capture finger prints using that machine.
the device is of NITGEN company.
and the model is FINGKEY HAMSTER.
please provide me help for this.

If you need to interact with a specific piece of hardware, the first place you should be looking is to the hardware vendor. The second thing you should realise is that, unless the hardware vendor supplies a high level API, you're going to have to do this in C or C++.
|
|
|
|
|
The hardware company provides the SDK with the hardware. but it is readymade software attached with it. but i want hardware to be connect with my application. i have their exe and dll. but i think they have made it using vc++. can i have any software that can convert this dll or exe into code ???
or is there any such class of .net that can interact with these kind of hardware ??
THANKS........

Adding a reference only works with COM-based libraries. This one, apparently, is not of that type, so you'll have to call all the functions it exposes using P/Invoke.
|
|
|
|
|
Thank you so much.
I am checking it now with p/invoke.
hope it works.
|
|
|
|
|
ok. i found p/invoke.
but still i am not able to connect device to my application.
i am not much aware of use of p/invoke...
can anyone please give me a example how to use dll in p/invoke?
