"Open with" question

[kimiraikkonen]

Hi,
I have small project which opens text files via inside the project but
i want to associate this app for every text file. To have a test, if i
right click on a text file -then "open with" -my application...
but my app's text area(textbox,wh ere the text data is loaded into. )
is opened blank, nothing is displayed except a general view of my
project app

How can i make "open with" association to display text with my project
properly?

Thanks.

All an "open with" association does is launch the associated
application with the complete path to the file clicked on in the
Command Line. It is up to your application to see that there is a file
name in the command line and process it appropriately.

Your application would likely accept the path to the file on the
command line. You then parse the command line during application
startup, load the file and display the content in the text box.

If the form's Load event. Check the contents of the
Environment.Com mandLine. If there is a filename present, open it, read
the data, and put the data in the textbox's Text property.

The principle is the same in a Windows app. You can still have a
parameterized Main entry point, or you can use
System.Environm ent.GetCommandL ineArgs() from anywhere in your code.

Hi again, could you sample some code and will i put them in form_load
event?

Assume, i have a textbox and openfiledialog control and i use
streamreader to display texts.

Thanks.

I believe all you need to do is this:

Dim arguments As string() = Environment.Get CommandLineArgs ()
Dim fn as string = arguments(0)

if (System.IO.File .Exists(fn)) then
MyTextBox.Text = System.IO.File. ReadAllText(fn)
endif

Hi, that doesn't work :-( Only "MZ" is displayed textbox with no sense.

The first argument ('Arguments(0)' ) seems to contain the path to your
executable file. 'MZ' are typically the first characters in executable
files.

Thanks Herfried. I wasy typing without a compiler. I believe the command
args are starting at index of one as you said.

Hi there,
After trying to figure out where and what the codes are used for i
managed to what i was trying to by adding to form_load event:

Dim cla As String() = Environment.Get CommandLineArgs ()
If cla.Length 1 Then
myStreamReader = System.IO.File. OpenText(cla(1) )
TextBox1.Text = myStreamReader. ReadToEnd
myStreamReader. Dispose()

'After text is opened, all the texts come up as selected, thus i added
to make them unselected.
TextBox1.Select ionStart = 0
End If

Hi,
I want to ask this:

Why was i forced to use:

If Arguments.Lengt h 1 Then
Dim fn As String = Arguments(1)

'do stuff

end if

For example when i want to display the current app's path:

Dim cla As String() = Environment.Get CommandLineArgs ()

Msgbox(cla(0))

shows "exact" path in messagebox, no other extra or unwanted strings
like "MZ", so it would be kind of you explaining this issue.

Thanks.
