Can anybody tell me how to connect to a *.dbf file?
I tried via odbc and oledb.
ODBC
Driver={Microsoft dBASE Driver (*.dbf)};DriverID=277;Dbq=" + txtbox_filepath.Text + ";"
DRIVER={Microsoft dBase Driver (*.dbf)};DBQ=" + txtbox_filepath.Text + ";DriverId=533;MaxBufferSize=2048; PageTimeout=5"
OLEDB
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + txtbox_filepath.Text + ";Extended Properties=dBASE IV;User ID=; Password="
I've tried different variations and google and msdn tell me nothing new.
(txtbox_filepath.Text gives the path to the file)
I only try to open it and close it, but it still fails. The error message is something like invalid path, but after double and triple checking this, Removing the path (leaving the filename) and trying to add the directory with the odbc sources (via administrative tools), it still doesn't work 
I'm at a loss here, hope somebody can help me...
tnx.
No hurries, no worries.

I create a registry key when i run at the first time my application (not during the installation).
I would set some parameter to the unistalling process that allow to delete that key or another key created by another software.
How?
Tnx.

Hi,
I am developing an wireless network monitoring tool. I am using CreateFile, DeviceIoControl and CloseHandle. So this is the plan to create the file to open the NDIS device any make the OIDs query. My problem the name of the file could not be mentioned. I took some help from rawether and some samples. But the Driver name "Ndisuio", when i create the file it returns the handle as -1. So i need the correct format of Specifying the first parameter(the driver filename) to the CreateFile. The code Actually is,
private const string NDIS_FILE_NAME = @"\\\\.\\Ndisuio";
DriverHandle = CreateFile(NDIS_FILE_NAME,
GENERIC_READ | GENERIC_WRITE, 0, 0,
OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL,
INVALID_HANDLE_VALUE);
My Question Actually is what this suppose to mean :" \\\\.\\Ndisuio". and how to make it relevent to my system. I am using Windows 2000 professional Built in NT technology.

Well Sanjeev, everything seems fine.... but there is one glitch which might be causing this problem. Since you are picking value from a textbox, perhaps there are trailing spaces in it. Why dont you first extract value from textbox, trim it and then try to find that node.
Like you can do this.
string strdata = Convert.tostring(textBox1.text).trim();
xmlNode farm2=doc.SelectSingleNode("/root/farm-config/farm[./@name='"+ strdata + "']/connection/@address");
Hope this resolves the problem!!!

I have a solution that contains 4 projects. The main project is entitled Majo, which uses the Majo namespace IE:
namespace Majo
{
public class Majo : System.Windows.Forms.Form
{
...
In the Components project I have the following declaration:
namespace Majo
{
namespace Components
{
public class ImageComponent : PictureBox
{
....
The problem is I need to have access to the Majo class within the main Majo namespace, but if I just use Majo from the Components namespace, I get a
'Majo' denotes a 'namespace' where a 'class' was expected
How can I gain access to the Majo class from Components? Thanks.

Majo.Majo majo = new Majo();
IMO you'd do better to change the namespace name, it's potentially confusing.

I still get a
The type or namespace name 'Majo' does not exist in the class or namespace 'Majo' (are you missing an assembly reference?)
error if I attempt to use Majo.Majo. Is there someone I have to do to be able to reference the main class?

LOL - I assume this is a typo.
I would still recommend changing the namespace name. Other than that, it's a strange problem, I'd expect it to work that out for you.

For some URLs (e.g.http://v3.espacenet.com/origdoc?DB=EPODOC&IDX=WO2005028634&F=0&QPN=WO2005028634), the content length for the HttpWebResponse I get with request.GetResponse in empty. The response.GetResponseStream() also empty.
Here is the code snippet:
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(pageAddress);
HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
StreamReader sr = new StreamReader(resp.GetResponseStream());
string pageData = sr.ReadToEnd();
The Content Type for the response is "text/html; charset=iso-8859-1" and the HttpStatusCode was OK.
What am I missing?

hi to all,
is there a way to embed a 'live' preview of what is being captured into a windows form ?
rather than launching the twain interface then capturing and sending the captured data back to the form ?
tutorial or similar would be nice 
have looked at leadtools & imagXpress but they launch the third party twain interface
kind regards

There's no TWAIN support built in to the .net framework.

does this mean it is impossible to do this ?

It means no matter what happens, you need to write a TWAIN implimentation, or buy one. Once you do that, I see no reason why you can't render the image being scanned where ever you feel like it, assuming you have that level of control in the code you buy, or write it yourself.

well thats wot i thought, however i downloaded a trial of imageXpress and i cannot see anyway to avoid the twain interface appearing as a secondary process.
note: twain interface in this post refers to the UI not the hardware interface
what i would like is capture froma a twain camera (acting as a web cam), and if the person moves then this is reflected inside the windows forms application. and capturing of the 'video' will result in a still being placed in the same location (or other...)
however, my current implementation..
when you click acquire it pops up the twain interface (where the above description takes place, as opposed to inside the c# app) and on clicking 'get pictures' or similar, the picture is sent back to the windows forms app.
this is what i am trying to acheive and i have googled for a long time and found no suggestion that this is possible, however i assume it is as the twain interface itself is doing this.
kind regards,
g00fy

I was looking at this[^] the other day and it seems good. I haven't researched further because I haven't had much time, but it might work for you.

Yeah, well, that's generally how it's done, so that's probably what they support.

Doesn't DirectShow let you do this ?

Yeah, I'd assume so, too. But I've never done anything like this, when I did TWAIN stuff, it was for a scanner, with the sort of interface you suggest.
