Hi
You Can Use This Function To Convert NetworkPath To LocalPath
Private Function ConvertToLocalPath(ByVal NetworkPath As String)
Dim LocalPath As String = "D:"
Return LocalPath + NetworkPath.Substring(NetworkPath.IndexOf("\", 2), _ NetworkPath.Length - NetworkPath.IndexOf("\", 2))
End Function

This is easy using the Path class in the System.Io namespace:
Imports System.Io
.
.
.
Dim root As String = Path.GetPathRoot("D:\some\file.path")
This also works just as easily with a UNC path.
Or are you asking how to determine which drive letter is being mapped to a UNC path??

hi guys
i want to print windows based report on dot matrix printer. is it possible?
if yes what will be the h/w , s/w requirement for it ? and coding structure for it in vb.net. since i have developed report in vb.net2005 & crystal report.
Thanks

As long as the printer has a windows printer driver and you communicate with it using that driver only (no escape code injection etc) then the hardware layer should be of no consequence - it should just work...
|
|
|
|
|
thanks for reply. then what should i do for printing on dot matrix ? pliz. suggest me code.
Thanks
bye
|
|
|

He just told you! It's no different that if you were printing to a laser printer.
Crystal Reports will handle generating the image of the page and pass that to the printer driver which will convert that into the native language of the printer. There's nothing your code has to do any different.

I have a form and if you load another form from that, the first form gets hidden, but not closed, so, how can I get the whole application to close if the exit button on the top right corner of the program is cliced rather than the exit button I placed?
In the end we're all just the same
|
|
|
|
|
hi
to close the application use - application.close()
& to close the current form simply use - me.close()
Thanks
bye
|
|
|
|
|
But I used
FrmFinance.hide () as I wanteded it that way because I had information I wanted to display on it temp while the application was open. If I put frmFinance.close () you would lose the information
In the end we're all just the same
|
|
|
|
|
depends on what you want
say you have 2 forms frm1 and frm2
frm2 is opened by clicking a button on frm1
then you can hide frm1 like you are doing without problems
now from here it depends on what you want
if you want both forms to close when the user presses the close button from frm2 you use
application.close
if you only want frm2 to close you use me.close (and bring frm1 back out of hiding)
use the frm2.close event to do this
hope it helps

I have a file CarSales.txt and its in the same directory as the program itself, but I keep getting "file not found" when I run the program. How would I get the program to find this file? code:
Dim sr As New StreamReader("CarSales.txt")
In the end we're all just the same
|
|
|
|
|
use application.startuppath
so code would look something like this:
dim sr as new streamreader(application.startuppath & "\carsales.txt")
hope it helps

You should always use the fully qualified path to a file and not just assume the current directory is the one you think it is.
If your file is in the same folder as your .EXE, you can get the full path using something like:
Public Shared Function GetFullPathToFile(ByVal filename As String) As String
Return Path.Combine(Application.StartupPath, filename)
End Function
If it's in a subfolder of your application's folder, there are several different ways of building the path. A simple implementation would be something like:
Public Shared Function GetFullPathToFileInDataFolder(ByVal filename As String) As String
' Build the full path to the Data folder in our the folder our .EXE is in.
' You could also get this path from a config file, or some other data store.
Dim dataFolderPath As String = Path.Combine(Application.StartupPath, "Data")
' Then build the path to the requested file
Return Path.Combine(dataFolderPath, filename)
End Function

hi all
i have some lines of code which generarte menu at run time.now i want to pass the index value of menu to another function.hw to do so plz help me....
[code]
For i = 1 To n
s = "Select account from cash"
com = New OleDbCommand(s, con)
con.Open()
dr = com.ExecuteReader
While dr.Read()
a = dr(0)
b = a
Dim mSubSubMenuItem As System.Windows.Forms.MenuItem
mSubSubMenuItem = New System.Windows.Forms.MenuItem
mSubSubMenuItem.Index = i
mSubSubMenuItem.Text = b
mSubSubMenuItem.Enabled = True
mSubSubMenuItem.Visible = True

i = i + 1
End While
[/code]
i want to pass the value of i to MenuClickHandler
poonam

easyst way would be to put i into the tag property of mssubsubmenuitem
then in you'r menuclickhandler cast sender to a menuitem and you can extract i from the tag property again
code would look something like this:
While dr.Read()
a = dr(0)
b = a
Dim mSubSubMenuItem As System.Windows.Forms.MenuItem
mSubSubMenuItem = New System.Windows.Forms.MenuItem
mSubSubMenuItem.Index = i
mSubSubMenuItem.tag = i
mSubSubMenuItem.Text = b
mSubSubMenuItem.Enabled = True
mSubSubMenuItem.Visible = True
AddHandler mSubSubMenuItem.Click, AddressOf MenuClickHandler
mShowMenuItem.MenuItems.Add(mSubSubMenuItem)
i = i + 1
End While
private sub MenuClickHandler (sender as object , e as system.eventargs)
Dim menu As System.Windows.Forms.MenuItem = sender
dim i as integer = menu.tag
end sub
hope it helps

I intended to have the App.config file as a sort of config.ini file and have set up many application variables there.
However i noticed that the .exe file does'nt complain if the app.config file is not around, so i can only assume that the file is embeddded into the exe file when the solution is built.
Is this so or can i update the app.config file for different situations without having to change code?
Regards

An app.config file is not required to run the app. It just sets certain options in your app when it runs, or is used to store values for future use. The file is NOT required to run the code.
Also, it's not compiled into the .EXE. It always stands as it's own seperate file.

Hi all...
I have the following piece of code:
Using HeaderReader As New StreamReader(HeaderFilePath)<br />
While Not HeaderReader.EndOfStream<br />
Dim EndFileHeaderWriter As New StreamWriter(filepath, True)<br />
EndFileHeaderWriter.WriteLine(HeaderReader.ReadLine())<br />
EndFileHeaderWriter.Close()<br />
End While<br />
End Using
Now i wanted to write a flat file and each line should be in a new line... instead this code is adding the text next to the previouse line... Like so...
Test line1Test line2Test line3
i wanted it like this...
Test line1
Test line2
Test line3
What am i doing wrong?
i am using the WriteLine and not the Write ???

If WriteLine isn't doing it, try adding Environment.NewLine to create a line break. That's what WriteLine does, tho. If you step through, are you sure that each line you are looking for is read seperately ?
