Hi All,
This is the first time, am posting a query on any forum.
I've developed an application in which there is a hot key assigned to each button. In VB.Net I came to know there is no need to press Alt to activate the hot key which is known as an Access key (correct me if am wrong). But problem is like this when my application is open and control is on my application and by mistake if I pressed any button for eg. on Exit button, I've written E&xit so it's a hot key when I pressed Alt+x, but according to Access key if I press 'x' then also it works as Alt+x and it takes me out of the application. So I wanted to deactivate the access key, it should work only when I pressed Alt+x.

Please advice me.

load assembly from appdomain?

Sorry to be a pain, but I just can’t find this:

I can load an assembly from a .dll:
Dim Asm As Assembly = System.Reflection.Assembly.LoadFrom("c:\test.dll”)

But then I can’t unload the assembly

So I tried:

Dim newDomainName As AppDomain = AppDomain.CreateDomain("newDomainName")

But NewDomainName doesn’t have a loadfrom method

How to create the assemblyref foo required as the argument in:

newDomainName.Load(foo)

Thanks

If the grid is bound to a datasource, you don't add the new row to the datagridview. You add it to the datasource, probably a DataTable. How you do that depends entirely on your datasource.

Check out Blat.

This is a freeware mail program that is command line driven - so you should be able to quite easily integrate it into your code.

I use this to automatically send out emails to suppliers notifying them of payment transfers.

You always pass failure on the way to success.

I'm okay helping you with specific questions.

As a hint - you will need to use the shell to execute the blat commands as it is command line driven.

I don't consider just over one and a half hours, between my post and your reply, as worthy of the phrase:

If you were using VB.NET, this would be trivial. The other option that sprngs to mind is MAPI ( which can use outlook express, I belive ), but I have no idea if VB6 supports it in any way.

Can we read return from a process without waiting its completion?

ATC17-Oct-07 7:59

17-Oct-07 7:59

With the help of Pete (earlier post) I am able to read & display return lines then close a process through command line (MS-DOS window) with the following codes:

<br />
        Dim ps1 As New Process<br />
<br />
        ps1.StartInfo.FileName = "cmd.exe"<br />
        ps1.StartInfo.WindowStyle = ProcessWindowStyle.Normal<br />
        ps1.StartInfo.CreateNoWindow = False<br />
        ps1.StartInfo.UseShellExecute = False<br />
        ps1.StartInfo.RedirectStandardOutput = True<br />
        ps1.StartInfo.RedirectStandardInput = True<br />
        ps1.Start()<br />
<br />
        Dim s1 As String<br />
<br />
        Dim sIn As StreamWriter = ps1.StandardInput<br />
        Dim sOut As StreamReader = ps1.StandardOutput<br />
        sIn.AutoFlush = True<br />
        sIn.Write("dir/p" & System.Environment.NewLine)<br />
<br />
        Thread.Sleep(100)<br />
        s1 = sOut.ReadLine<br />
        ps1.Kill()<br />
<br />
        ListBox.Items.Clear()<br />
<br />
        '// *** Display every return line *** //<br />
        While s1 <> "End of Line"<br />
            ListBox.Items.Add(s1)<br />
            s1 = sOut.ReadLine<br />
        End While<br />
<br />
        ListBox.Items.Add(s1)<br />

However, if the process does not stop then the ListBox can not update data (I think because the process takes more priority then the ListBox?)

1. Can we modify the above codes so that we can update the ListBox without waiting the process completed?

2. If it is not possible ... is there another way to do it?

Thanks for any help! D'Oh! | :doh:

I love how you wait one tenth of a second, read a single line of it's output, and then kill the process, whether it's doing something or not. Then you continue and try and read lines from a process you already killed off. You cannot do that. The process object must stay running in order for you to read from it's output stream.

ATC wrote:

This is because the UI thread is running the code to read the output stream from the process. Until the read operation and filling of the ListBox is done and your code goes idle again, you're controls cannot repaint themselves because the thread is busy doing other things.

ATC wrote:

Priority has nothing to do with it. Threading does.

ATC wrote:

You cant read hasn't has been output, so no. You have to wait for the process to finish. If by this statement you mean that you want the control to repaint itself and continue to fill the ListBox with data, you either have to move the code that reads the output stream to another thread, or you have to read the output stream asynchronously.

Would background workers fit in this solution? If not, why?

Sure. BackgroundWorker is just a wrapper for a pool thread. It'll do the job just as easily.

Hi,

AFAIK the general solution that will cope with both stdout and stderr, no matter how much
data is expected, requires several threads:
- one thread (other than the GUI thread) that reads lines (not ReadToEnd) from stdout
- one more thread (other than the GUI thread) that reads lines from stderr
- the necessary Control.InvokeRequired and Control.Invoke() stuff to let them access
your GUI
- and maybe yet another thread that waits for the process to terminate (if that is
relevant to your app).

And even when you program it according to the documentation (study it!) you will
find it difficult to get it to work properly on Win95/98/Me (IIRC that's how it used to be
on .NET 1.0/1.1 anyway).

Performing drag and drop between two datagridviews?

Hi I need to perform drag and drop between 2 datagridviews containing the same type of information? I want to drag and drop the entire row not just a cell value. If the user drags and drops a row from the source onto a row in the target then I want the fields to be updated please help... cant find anything online so far?

Drag and drop isn't exactly the easiest thing to understand. Newbie's to it get really confused about which side is supposed to be handling what, what Effects are, how to get the data out of the event args, what Data Formats are, how data is even represented in the operation. In your case, your doing it all inside your own app.

Learn the basics of drag and drop first before you start applying it to your DGV's and posting up DataGridRows into the operation. Start with creating a ListView that is a drop target and can take files dragged to it. Drop a ListView on a form and enable it's AllowDrop property.

Private Sub ListView1_DragDrop(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles ListView1.DragDrop
    If e.AllowedEffect And DragDropEffects.Copy = DragDropEffects.Copy Or _
        e.AllowedEffect And DragDropEffects.Move = DragDropEffects.Move Then
        Dim items As String() = DirectCast(e.Data.GetData(DataFormats.FileDrop, True), String())
        For Each item As String In items
            Dim lvItem As New ListViewItem(item)
            ListView1.Items.Add(item)
        Next
    End If
End Sub

This is just the Drop side of a Drag and Drop. Once you completely understand every line of this code, you can start experimenting with starting your own Drag.

Why all this step-by-step crap?? Because it's what confuses everyone who starts out. They can't keep the two sides of a Drag and Drop straight in their head, and therefore can't keep it straight in their code either.

* Set up a proxy server and flow all traffic through that.
