Hello!

First off I'm using Microsoft Visual Basic 2005 Express Edition. And I'm a newbie.

I've been trying to find a way to read a text file from a friends server and save it into a string. This file will only contain the numbers 0-100.

I searched the many forums I use but I'm either blind or not searching for the right thing. Any help would be appreciated.

Thanks

What kind of server?

If it's a Windows server exposing a share, then you can use something like this:

Dim x as String = my.Computer.FileSystem.ReadAllText("UNC path to file")

This, of course, assumes you have a working knowledge of Windows Networking.

I think hes just using a personal server on window xp, so like apache. I don't know to much about windows networking but I can do some googling.

Pretty much all he gave me was this 'www.hisdomain.com/filename.txt'

You have to KNOW, not guess, what kind of server this is. Without knowing, you're just guessing and wasting your time.

Apache is a web server.

Alright I will contact him. I'm about 90% sure hes using a windows server.

Is there any other way of doing this besides UNC? Just in case.

Thank you for your time by the way, sorry for me being a newb.

He could run a webservice that you can call to get the files contents.

That's the problem. There's LOTS of different ways of doing this, all of which depend on the type of server he's running, be it Windows Networking, HTTP server, FTP server, TFTP server, web service, ...

Alright I got a hold of him. Hes running Windows XP Home, with some program called wamp. He says it's Apache, mysql, and php put together. Hes not a genius on networking either so hes not really sure what kind of sever that would be.

So I copy my vb.net solution from one computer to another. On the new one I get:

The project includes a password-encrypted key for signing, and I'm supposed to enter it.

I swear I never gave any such thing...

How can I find out what it is?

Thanks

Open up your project and double-click on My Project in the Solution Explorer. Click on the Signing tab. What's enabled (checked) ??

OK, I had sign the click-once manifests checked. Problem seems to go away if I uncheck that.

Is there a good source for vb.net deployment issues? I'm having a lot of trouble with this part.

Thanks!

Nope. It's pretty much spread out all over the web. Run into a problem, then Google it.

I have a combo box, it is populated from excel (sheet 1, column A for reference sake). In sheet 1, column B is a flag set for items that must be reported immediately. Once a value is selected from the combo box it is stored in a text field on a form. I now need to find out if the value stored has the flag set in its column B.

If this is possible please let me know.

Thanks,

Dan

Combobox has Text & Value Properties.

Bind ColumnA to Text property, and ColumnB to Value property.

Ex:

<br />
Combo1.DataSource=ds;<br />
Combo1.DataTextField="ColumnA";<br />
Combo1.DataValueField="ColumnB";<br />
...........<br />
...........

Then, use the SelectedText and SelectedValue properties of the combobox.

Hope that helps you.

Dear Sir

I have created 2 forms on VB .NET.
Form1 has a Panel1 with 25 Buttons inside this panel.
Form2 has a Panel2 which is an emty panel.

My question is that:

If i click on any of these buttons one-by-one (Panel1 with 25 buttons), I want this buttons to be added
one-by-one into Panel2 and hold their sort of reference of click_event.

Im a student and very new to VB .NET

If you can u help it would be very grateful to me...

Kind regards

Roni

I already told you you either have to create a SECOND button to put on Panel2, or you have to MOVE the button to Panel2, which I also already showed you how to do.

You CAN NOT have a single button show up in 2 Panels, or any other containers, at the same time!

That explains why you're having so much trouble. Buy a book that takes you through the basics and then ease into winforms and so on. What you want to do can be done with delegates, but I can't imagine why you'd do it.

The method or operation is not implemented.

I am haveing trouble converting some vba come code to .net. The function call states that the ITrackCancel need to be there but does not need to be used. However when I don't pass one I get an embedded com error. When I do pass a new ITrackCancel I get a "The method or operation is not implemented. This item has several methods that could be implemented but I would have make it a global object to do this (I think). Does anybody have any suggestions on some things I could do with this to make it work?

The unimplemented functions look like this in the imed window
CancelOnClick = {"The method or operation is not implemented."}
CancelOnKeyPress = {"The method or operation is not implemented."}
CheckTime = {"The method or operation is not implemented."}
ProcessMessages = {"The method or operation is not implemented."}
Progressor = {"The method or operation is not implemented."}
TimerFired = {"The method or operation is not implemented."}

You have to create a class that implements ITrackCancel and supply the code to implement the methods. From your code, it looks like you don't know what an Interface is.

Public Class MyTrackClass
    Implments ITrackCancel
 
    Public Sub ....whatever methods you MUST code to satisfy
                   the requirements of the ITrackCancel interface...

End Class

'Set Cancel Tracker

The two Dim statements as Interfaces are unneccessary. Assuming that you have two classes that implement these interfaces (as above), what you did is no different than:

Dim pArr As New StrArray
pArr.Add(strPMFFile)

Dim pCT As New TrackCancel

Thanks for your help. I implemented the class and of course had to implement another class for something in there and now just get a HRESULT error Frown | :(

Oh well I will have to see what I can make of that.

No I don't know or remember what an interface is. I only seem to get to program about 3 months of the year so I forget alot between. Thanks for your time and patience. i am curious thought why all the examples from ESRI (Which is where all this comes from always do the
dim P_Interface as Iinterface
p_Interface = new interface

when you say its not neccessary. I have been doing it that way for a long time now.

Because an Interface is not a concrete object. It's more like a contract. An interface just defines what a class MUST implement.

Think of it this way. If you were writing a plugin for another application, how would that application know how to call the code in your plugin?? The only way is to make sure that the class you write implements an interface that the host application expects your class to use. Otherwise, the host app has no idea how to call your plugin code.

Now, since the host app also cannot know what your class is called at runtime, it just casts an instance of your class to the interface is expects. This allows the code to call your class because, without knowing what your class is called or what's in it, it knows that your class has to implements the things it DOES know about.

For example:

Public Class MyPlugIn
    Implements IAppPlugin
 
    Public Sub SomeMethod(blah, blah) Implements IAppPlugin.SomeMethod
        .
    End Sub
End Class

And in the application, it would do something like this (simplified!)

' An instance of the class has already been created somewhere
' else.  This is how the host app would use it.
Dim p As IAppPlugin = DirectCast(someInstance, IAppPlugin)
p.SomeMethod(argumentList)

The ESRI examples are overblown. They're doing extra steps that are just not necessary.
