I would like to create a text file with some data i am manipulating in a script component and write it to a text file. i know how to write it to an existing text file, but what i would like to do is create the text file programmatically so i can name it textfile(TodaysDate).txt
How can i do this??
You can call File.CreateText(someString).
This method returns a StreamWriter which can be used to write to the file.
Remember to close the StreamWriter usinga using statement.
If you start with a sample of the text file that you want stored somewhere, you can use a file system task to copy the sample file to the correct name (make sure you copy so that it's still there for tomorrow). Then use an expression to set the file location in the file connection manager.

I want to ask from users to load an excel file as an input data. this process must be done by opening a browsing window to select excel file.
what can I do?
You can use open_dialog_native from Gtk.jl.
julia> open_dialog_native("Choose the input Excel file", GtkNullContainer(), ("*.xlsx",))
"/path/to/myfile.xlsx"
It opens the file chooser interface appropriate to the user's OS, and once the file is chosen, returns the chosen file's full path as a string.
The ("*.xlsx",) is a tuple that constrains what type of files are shown by default in the file chooser. (The GtkNullContainer() argument just specifies that you're not running this as part of an existing GTK app.)

I tried to create a SSIS package to input excel file into database.
The excel file has dynamic name, and also i need to add filename into the database as well.
What I'm trying to do:
use for each file loop to set a variable called FileFound, with the value of
the filename (with full path)
set connection for the input file with above variable
use data load to load the excel to db, with above connection.
I got error saying the connection is invalid.

There is step you missed when using dynamic file names in a foreach loop. You need to set delay validation property of the dynamic source (in your case the Excel Conn) to TRUE.
The package tries to validate in pre-execute phase unless you delay it.
I have created a text file named 'Notes' in the resources of my project and want to load/save the text of a RichTextBox to it. I tried using MyProject.My.Resources.Notes in the path. It doesn't show any error in the code window but when I run it, it shows an error.
Here's what I'm using to load the text:
RichTextBox1.Text = System.IO.File.ReadAllText(MyProject.My.Resources.Notes)
Here's what I'm using for saving it:
System.IO.File.WriteAllText(MyProject.My.Resources.Notes, RichTextBox1.Text)
This is not a duplicate. I did not get an answer from the other question
Why don't you use a regular file which always works fine or a database?
Edit: maybe this helps?

How can I append text to the end a line in a text file with lines already there in VB.NET?
For example my text file looks like this:
header1,header2,header3
value1,value2,value3
stuff1,stuff2,stuff3
and I want to add new text to the end of each line so it looks like this:
header1,header2,header3,newheader
value1,value2,value3,newvalue
stuff1,stuff2,stuff3,newstuff
I know that in Perl you can point to the line and then act on it, is there some VB.net way to do this?
If the file isn't too big, the simplest is, probably, to use the IO.File.ReadAllLines method to read the file into memory and modify the data and write it back with the WriteAllLines method.
For very large files you're probably looking at reading each line modifying it and writing it to a different file.
I am using the "Download File" action in Install4j, and I need to use a variable in the text field where you specify the URL from which to download the file. I know that I can use a variable like this: ${installer:codebase}. However, I need to append the file name onto the end of that variable. Does anyone know how to do that?
I have tried ${installer:codebase}filename.jpg and ${installer:codebase}+filename.jpg, but neither seem to be working.
Installer variables are simply replaced in text properties. For example, if you set it to
${installer:codebase}/filename.jpg
and the value of "codebase" is set to "http://mycorp.com", then the text after replacement will be
http://mycorp.com/filename.jpg
