Does Visual Basic.NET or VC.NET provides some native support/APIs for programming the WLAN card
Can any one help me?? Urgent

The .NET Framework doesn't include ANY native support for working with ANY hardware. In the NT Kernel environment, all hardware is abstracted from the application. This means that you have to rely on either making your own DeviceIOCTL calls to the devices driver or using an SDK for the hardware.

I'm trying to catch messages sent to a window in VB6
This is how it's done in .NET but how would i do it in VB6
Protected Overrides Sub WndProc(ByRef m As Windows.Forms.Message)
If Int(m.Msg) = 301 Then
Dim res As Integer
res = meD.putDevice(93, "") 'just a function call
Else
MyBase.WndProc (m)
End If
End Sub
Please help!
regards/Jocke

It's nowhere near as easy to do in VB6. You have to replace the existing WindowProc with your own. Check out this[^] example for the code.

I've just installed 2005 Beta, and it is quite a bit different to 2003 that I am currently using. I'm writing VB code. When I used by 2003 app, 2005 upgraded it and I then found I have a lot of errors.
I need to finish this application and I would like some advice as to whether I should stick with 2003 or move on?

if you're finishing up your application and geting ready to release it into the wild before the v2005 release date, then i'd say stick with 2003 for now. otherwise i believe you're going to have to sign up for the go-live license.

I'm supposed to do a project using only XML, Microsoft Excel and Vb.Net. My problem here is that I'm supposed to plot a graph out with values extracted from an Excel file. Are there any ways to plot the graph without considering the size restrictions in Vb.Net (the size of the graph might be big), and how do we extract the values from the Excel file?
|
|

You can extract the values from the excel file using following code:
Private ds As DataSet
Private myCommand As OleDbDataAdapter
Private myConnection As OleDbConnection
Private Sub FillDataSet()
myConnection = New OleDbConnection( _
"provider=Microsoft.Jet.OLEDB.4.0; " & _
"data source=E:\EmbedBday\Bday.xls; " & _
"Extended Properties=Excel 8.0;")
If Not myConnection Is Nothing Then
myCommand = New OleDbDataAdapter( _
"select * from [sheet1$A1:A35]", myConnection)
If Not myCommand Is Nothing Then
ds = New DataSet
myCommand.Fill(ds)
myConnection.Close()
End If
End If
DataGrid1.DataSource = ds
End Sub
where "Extended Properties" refers to the MSExcel version on your system which is Excel 8.0 for version higher than Excel 97(inclusive).

can i write a textfile on an ftp using vb.net? the textfile is situated on my ftp. i want that when i click on send the textfile will add my words in that textfile which is on the ftp. Can i make this happen using vb.net??
|

|

Sure. You have to download the file to your machine first, modify it, then upload it back to the FTP server. An FTP server caanot be used like any other filesystem. It doesn't support "random access" like your local file system.

I can't modify my textfile within the ftp then??
|
|
|
|
|
No, there is no FTP command to "append text" or similar. As stated you can download the file, access it and upload it back.

Search the articles for "FTP". You'll find a bunch of examples, mostly in C#, but they get the concepts acrossed.

the articles from here?? on codeproject? because i am not finding a suitable one for me!

What, you want'ed it to be cut and paste and do everything exactly how you needed? It doesn't work that way. You have to read the articles and study the code to see what's going on so you can "roll your own". The articles and code samples are meant to teach techniques, not be free code snippets that work like plugin modules.

This group "LEARNVBDOTNET" is a yahoo group of close-knit individuals who are gathering together to learn VB.Net under the guidance of Bill Dennis. He uploads lessons and files periodically to the group. This is not a site which you would use in place of CODE PROJECT though. It is for individuals who want to learn with others at the same level of experience as themselves in a very personal and interactive level. It is owned and operated by Bill Dennis. I am just a member, but found it usefull enough to make me want to share it here with my fellow CODE PROJECT lovers. I am not trying to advertise a competing site at all. Check it out and you will see what I mean.

If you want to read a text file every 2 seconds, drop a Timer on your form and set it's Interval for 2000 milliseconds. In the Tick event for the Timer, put your file reading code.

where do i want to put the reading code? in the timer or in the formLoad? and how can I make the code?
|
|
|
|
|
Hello,
You would put the code in the Timer's Tick Event... just double click on the timer control and it should create the event for you.
To load a textfile into a richtextbox, look into the RichTextBox.Load(<parameters>) method.
I hope this helps,
Mitch
