Access A File Using Relative Path Or Virtual Path?
May 22, 2012I am trying to read and display a file using MapPath as follows :
Response.ContentType = "Application/pdf"
Dim FilePath As String = MapPath("../Document/123.pdf")
Response.WriteFile(FilePath)
Response.End()
This procedure will work fine and display in the browser. However, if I save the file to C:Document123.pdf, how can I access this file using relative path in MapPath function. Is there an option to access the file which is saved out of IIS server? I am using vb.net 2003.
Path Of .zip file Has Spaces In It / It's Not Recognizing Path As Valid Path
Aug 22, 2006I have a Access program and I'm using VBA code in the background to run Winunzip using shell command.

Has you can see I had to use progra~1 instead of Program Files.[code]

View 2 RepliesGenerate A Virtual Disk / Path?
Mar 26, 2009Is there some way to generate a virtual disk/path?My application needs to generate a lot of temporary small files, edit them, write to disk, execude old executables in Fortran, and read the text files outputs.I cannot choose to avoid the fortran, because is out of my power to decide it.all that I/O is really expensive, because disk access is slow. But all the files involved are really small (including the executable), so they may fit on a few megabytes of RAM, and I have gigabytes of RAM available (RAM is really cheap today).Worse, I cannot parallelize, because it forces me to multiply I/O operations (I need to create, edit, and delete lots of small files).The perfect solution would be to have a small virtual disk in memory.I cannot use a virtual PC software, because users would have a hard time installing it (they have problem using windows explorer even to do simple tasks).
View 4 RepliesUser Controls Virtual Path?
Nov 9, 2009I'm having a bit of a problem with the web application I'm currently working on. In it there are a few Web User Controls that we use to display information on a bunch of different pages. They seem to compile alright and arent showing up any errors. The problem is trying to register them on other pages to access them is returning a 'file not found' error in visual studio (2005). I have them defined like this:
<%@ Register TagPrefix="cc2" TagName="ControlSelector" Src="~/components/controls/ControlSelector.ascx" %>
The strange thing is that when I remove the '~' from the front no error is shown but the path beomes ~//components/controls/ControlSelector.ascx when looking at the designer and obviously it cant find the control anyway.

Feb 17, 2011Am not n a programming class am just interested in how things are done behind the scenes while learning. What is nice about this is that you can still learn by looking at code and trying to figure out what/how they figured it out. Am trying to work on this script and looking for some . Am to prompt the user to input a path to a folder in the c: Get a folder object to act as that folder and how to detect if the path which the useer entered is valid and if its not valid to display and error message and to go no further. Get a files collection that represents all files in folder the user selected Check number of files in the collection, it is "0" make a messsage box stating folder doesnt contain files and if it does make a message box stating the number of files in the folder.

DB/Reporting :: Error Access To The Path "PATH HERE" Is Denied
Jul 25, 2008when i try to write to a file I get the error:
Quote:
Access to the path "PATH HERE" is denied. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.UnauthorizedAccessException: Access to the path "PATH HERE" is denied.
ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user. To grant ASP.NET write access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.But when I add: <identity impersonate="true"/ to web.config I get the following error when my application trys to open a DB to read it:

2010 OleDb Text Connection String: "Not Valid Path"
Nov 7, 2010I've been all over the help files and finally patched together a VB OleDb connection string for delimited text files:
Dim connection As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & "Data Source=" & fName & ";" & "Extended Properties=""text;HDR=YES;FMT=Delimited"""
"fName" is passed in by an open file dialog.In every case (for all paths) it throws: 'C:1_2010NormalFileNormal.csv' (or where ever it is pointed) is not a valid path. Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides.Since no path works, it must be a syntax error, but I'll be darned if I can see it.
Full code of this routine is:
Dim connection As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & "Data Source=" & fName & ";" & "Extended Properties=""text;HDR=YES;FMT=Delimited"""
Dim conn As New OleDbConnection(connection)
