Asp.net - FileIOPermission Fails When There Is A '~' In The Path?
May 5, 2011
I'm catching the following error in a publishing script (VB.Net) I'm running:
Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
The code that fails is:
My.Computer.FileSystem.WriteAllText(path, content, False)
It runs fine for most of the files but some have a '~' in the path and those ones are all failing.
Just to clarify: i am using the full path an example of the path i am having problems with is "c:/websites/xml/myfile~test.xml" the ones that work are "c:/websites/xml/myfiletest2.xml"

I have a Access program and I'm using VBA code in the background to run Winunzip using shell command. Well, the path of the .zip file has spaces in it and it's not recongizing the path as a valid path. Is there a another way to tackle this problem besides the shell?I can't us pkzip either. Has you can see I had to use progra~1 instead of Program Files.[code]

Problem drawing dotted path lines, with even dots along the path line.I want to draw a path line that can be any shape (square, round, outline etc), and along this path line I want even dots to appear.
I also want to be able to resize the shape (as in the example attached)This is very easy to do using "DrawPath" and defining points for the path and using a pen defined as dots.The problem I have is I want the dots to be evenly placed along the path, on any shape or size I draw.In the example I have created, I create a square with 4 points and draw a dotted path.There are 2 buttons that allows me to resize the square (larger or smaller) this helps show the problem more clearly.
The path starts at the top left corner and finishes back at the top left corner, the dots are evenly placed along the path, except the final dots at the end of the path. (Sometimes the dots are even and other times they are not even).The shapes I want to draw can be any size and any shape, but I have used a square in this example to show the problem I have. point me in the direction I need to go that allows me to draw the dots and give the impression that they are even all along the path, for all shapes and sizes.
In the pictures below if you change the size of the shape, one will have even looking dots, the other will not.

I am trying to create a function to convert a mapped drive path to a UNC path. I did some googling and found several different pages on the matter. I am most interested in the first one, but I cannot seem to get the code to cooperate. Since the original post was in C#, here is my VB.NET conversion:

I 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.

I'm using acrobat that returns unix paths instead of windows path's. So im wondering if there is a way in vb.net to convert the path to windows path.
i tried using:
docs(i) = javaScriptObj.path().ToString.Replace("/", "").Substring(1)
position = docs(i).IndexOf("")
docs(i) = docs(i).Substring(0, position) + ":" + docs(i).Substring(position + 1)
this only works on local files, but fails when im starting to use network drives.

Well now i have an issue which is pointing in the use of "path's" physical and network.I have a SQL server on a Server machine and i have a desktop machine used as client.I'm runing from my client machine a stored procedure in order to add a streaming data base.But also before i run this procedure i run another one which prepare the desired "path", this procedure takes:
myPath="\ServerSharedFolderSQL
in order to run the first procedure i have to turn myPath in each physical name:
myPath="DriveLetter:PublicWorkFilesSQL"
Now my Issue is how i will have the physical path, which is build it on the server and which it's from very difficult (to imposible) to know it? Basically i need a function which will return me the physical path, which the implementation it's not knowing to me. My developing environment is vb.net 2010?

I am using this code below:

I thought the %AppData% should find the relative path. When I go 'Start|Run|%AppData% windows explorer takes me to that directory. I can not put the full path in, as the user is different on each client machine.

I have an .exe application written in vb.net. When I make shortcuts to the application, say on desktop (or anywhere else) and then click on them I want to programatically get the path to that shortcut, ie. C:/Users/xxx/Desktop/shortcut.lnk.
I want this so I can store the pairs shortcuts : (program + different cmd args).

I have a VB program that I'm trying to deploy. On my machine (the app works fine straight from VS), when I try to install it from the webpage, it asks me to setup .net. I only have a choice of repairing or uninstalling .net. I've tried both but both fail at the moment. The problem with the repair is, although it goes through the entire repair procedure, it then asks me to restart my PC, but when I hit 'restart', nothing happens. So I restart manually, but when I try again, I just have to go through the same procedure again.

Why is hi failing to even hit the event? This should be htting the event, I see no reason why it would not hit this event when I press the enter key, instead I get a beep sound.

when 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:

I wrote an application on windows XP using visual studio 2008. Based on the .net framework 3.5. For some reason that I do not understand the application refuses to run on windows 7. You would think that if the .net framework 3.5 was installed on the windows 7 machine it would run.

I currently have this line of code which has been working for the past 6 months:
If IsNumeric(txtProductID.Text) Then

Else
Dim msg As String = "Error!"
End If
All of the sudden, no matter what kind of entry is put in txtProductID (including plain numbers), it fails! Is there reason for me to be going crazy over this?

I am currently using the AsyncFileUpload in my VB.NET web app. Locally it works perfectly, however on the server it fails to upload a small file (<9k). I can't even seem to debug this as in JavaScript handlers I have no idea as to how to get the error reason.
function uploadError(sender,args) {
$get("<%=LabelErr.ClientID%>").innerHTML = "Unable to Upload file for the following reason: ", "<span style='color:red;'>" + args.get_errorMessage() + "</span>";

I have just finished my application using VB in Visual Studio 2005 and it works fine on my Win 7 development machine. But when I install and run it on an XP machine it fails with an unhandled exception:System.Runtime.InteropServices.COMException (0x80040154): Retrieving the COM class factory for component with CLSID {E8D851FA-9967-4ADF-9644-0183B9B1EA68} failed due to the following error: 80040154.
I've googled the error message and the solutions seem to be 1) compile as x86 (was doing that anyway), and 2) register the dll on the machine But firstly I'm not sure which dll I need to register, and secondly I don't want to be going around registering dlls - the whole point of the installation programs is that it should just install and configure everything automatically..
