How to save some variable for permanently

[saleem.mukhtiar]

Dear Friends i made a applicatoin where i need a variable value which will enter by after 1st installation...

Infact it is a uploading to ftp application with a single click. but the file name is not constant for all all locatins. So i want i will enter it in first run and it should be saved.

i think you understand what i want ...

You can use a custom setting. In the Settings tab of the project properties, set the name and the data type. You don't have to put a value if you don't need it. If the setting is called "Filename", your code would look like this:

 My.Settings.Filename = "MyFile.txt"

Thanks Tinstaafl ... here is the code File which i am uploading ... after uploading its going to rename ..... MSSAT001.DAT

Now you can give me a better solution

Public Class FrmUpload
    Public Function newext() As String
        Dim pickdate As DateTime = DateTime.Now
        Dim strdate As String
        strdate = pickdate.ToString("m")
        Dim strsplit() As String
        strsplit = strdate.Split(" ")
        If strsplit(0) = "January" Then
            strsplit(0) = "A"
        ElseIf strsplit(0) = "February" Then
            strsplit(0) = "B"
        ElseIf strsplit(0) = "March" Then
            strsplit(0) = "C"
        ElseIf strsplit(0) = "April" Then
            strsplit(0) = "D"
        ElseIf strsplit(0) = "May" Then
            strsplit(0) = "E"
        ElseIf strsplit(0) = "June" Then
            strsplit(0) = "F"
        ElseIf strsplit(0) = "July" Then
            strsplit(0) = "G"
        ElseIf strsplit(0) = "August" Then
            strsplit(0) = "H"
        ElseIf strsplit(0) = "September" Then
            strsplit(0) = "I"
        ElseIf strsplit(0) = "October" Then
            strsplit(0) = "J"
        ElseIf strsplit(0) = "November" Then
            strsplit(0) = "K"
        ElseIf strsplit(0) = "December" Then
            strsplit(0) = "L"
        Else
            strsplit(0) = ""
        End If

        newext = strsplit(0) + strsplit(1)

    End Function

            Catch ex As Exception

there is no permanent variable,
you need persistent storage like file, database

[tinstaafl]

What are you looking for that's better than using the settings?

When you rename the file, that's the filename you want to save. Just follow the instructions I gave you and substitute in the new filename. `My.Settings.Filename = "mssat900." & newext()

You might need to add My.Settings.Save(), just to make sure the setting gets saved.

You might find this better for your newext function:

Public Shared Function newext() As String
    newext = Chr(Now.Month + 64) + Now.Day.ToString
End Function

That should be the same output you're looking for. For instance today would return "E10"

Dear Tintaafl I want that i can cahnge MSSAT900.dat ... when i install the application

i mean ....
dim filename as string
DirectCast(System.Net.FtpWebRequest.Create("ftp://ftp.uibonline.com/uibsat/'&FileNname&' "), System.Net.FtpWebRequest)

then

Dim file() As Byte = IO.File.ReadAllBytes("C:\syn\bajrai\msdata\'& FileName &' ")

and in the end

My.Computer.FileSystem.RenameFile("c:\syn\bajrai\msdata\mssat900.dat", " "& FileName. &"" & newext() & "")

I just pass file name 1st time its starts after installation... some give me seggestion for Serialaization ... but i dont have idea about it also :(
