I am creating what could amount to quite a few temp files on a terminal server using the System.IO.Path.GetTempPath. My question is this. Can I trust Windows to clear that directory on a regular basis or do I need to clear it in code?

View 11 Repliesthe code below is for creating controls at runtiem, but i have realised even tho i remove the controls and then add controls, they are keeping their settings and more so the Data, eg the checked list boxes are keeping their data so if i do some work with 1 of the 3 pannels then when i change the pannel im working on it still has its lists, how would i go about using a 'frest template' as in a clear all previous settings just so their isn't any possable errors.

I'm trying to read a csv file. I'm also try to delete all files in the temp directory on the page load. Everything goes fine the first time, but the second time I get an error saying it couldn't delete the file because it is in use by another process. I'm aware that this process is my vb file, I just can't seem to find what I need to dispose of to get rid of the file lock.
Here is my code

The following code for installing log messages has worked on Windows 7 and XP, until I came across an XP machine where someone had deleted the Temp file under Documents and Settings/ComputerName/. Is there a safer location to install a log file?Path.GetTempPath doesn't seem to be the best idea.
Public Sub appendLog(ByVal message As [String])
Dim format As String = "MM/dd/yyyy HH:mm:ss.fff"
System.IO.File.AppendAllText(System.IO.Path. Combine(System.IO.Path.GetTempPath
, "Log.txt"), vbLf + " " + DateTime.Now.ToString(format, CultureInfo.InvariantCulture) + " " + message)

I'm the only one in the company using Windows 7 which we are evaluating to decide if/when we're going to upgrade all our PC's. I am a domain administrator and my PC is in the domain and I'm authenticated. Since I installed Win 7 I haven't had any other authentication issues. The apps are built on .NET 2.0 SP2 I don't know much about our domain setup which is handled by our network administrator but I'm told that the Primary Controller is a Windows 2003 and the Secondary is Windows 2000. He tells me that by default every workstation first authenticate on the Secondary controller if it's available.

Am trying to copy contents of file temp.fxl to temp.seq. I want them to look exactly them. I don't want to copy the file though. I use the following code
Dim fs As New FileStream("c:\fxlate\output\temp.fxl", FileMode.Open, FileAccess.Read)
Dim s As New StreamReader(fs)
[Code].....
With such simple code, the last line in temp.seq is truncated as attached and the size of the file is smaller than temp.fxl. See attached files. What do I need to do on the above code. Is VB.NET failing to write 1024 characters on one line.

View 1 RepliesI'm running Visual Studio 2010 on a terminal server, and have been, with relatively few problems, for some time. This morning I fired up my PC and over the UK's long weekend, the following issue seems to have developed.I've got a bunch of projects (but not all of my projects, and not all of the projects in a given solution) complaining that a particular file (which does not exist on the computer) cannot be opened, and so those projects will not compile anymore. Here's the error:
Error 31 Unable to open module file'C:Users[username]AppDataLocalTemp2.NETFramework,Version=v4.0.AssemblyAttributes.vb':
System Error &H80070003&
I could simply copy the file into that directory and be done with it, I'm pretty sure that will work,EDIT: Okay, now things have gotten to a whole new level of weird. I've rebooted the server, I get the same error message, only now the file it is asking for exists and can be opened in Visual Studio with no problems. another part of the IDE still insists that it's unable to open the module file.
EDIT 2: Can't delete the file because it claims to be open in another program, but I've logged off and logged on again, and there shouldn't be anything accessing it.
EDIT 3: Because there's a wall of comments below his answer, I'll mention here that Jared's suggestion to delete the SUO file for the solutions having the problem (not files specifically to do with any of the problem projects, strangely) was what solved this, eventually.

Using MS Access 2003 I am trying to build a command button in a form which clears the contents of a table column (which are tick boxes) - the idea behind it is this - the database is a contacts database for a club. Every year there is a subscription to be paid, so I want a column to annotate those who have paid (using a tick box). At the end of the year this will be reset - hence the reason for trying to produce a command button that clears out the ticks. What I using is this ....Private Sub Command11_Click()Dim strSQL As StringstrSQL = "UPDATE TBL-Master SET TBL-Master.campaign = '';"DoCmd.RunSQL strSQLEnd Sub(TBL-Master is the table name, campaign is the column name)What I am getting is a runtime error - 3144 -

I can't send email via ASP.NET and sent an email to my web hosts for some help and was told to modify my security settings and was sent a link:[URL]..I've read what it said there and tried setting <trust level="Full" originUrl="" /> in web.config, but then I get the error:
This configuration section cannot be used at this path. This happens when the site administrator has locked access to this section using <location allowOverride="false"> from an inherited configuration file.
I've not set any other web.config file.So I asked the web hosts again, and asked if it was a server setting which I cannot change, but the response I got was just:
You'll need to specify a more specific path. Which is lovely, but I've no idea what that means! Having done a bit more digging I am wondering if I have to set up a separate trust file, is this correct? Could someone point me in the direction of the correct way to set up my Trust level (I realise "full" is probably incorrect as well?) as I really don't understand what I am supposed to do!

View 3 Repliesadd a code to handle the TextChanged event of my Textboxes to clear the Result box.
Private Sub btnCalculate_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalculate.Click

What I have is on my form there are several text boxes. These text boxes are for user input and attached to each text box is a Private Sub txtBox1_KeyPress function. In that function I have some validation code to check that the user is inputing only what I want them to. And if it doesnt it will pop up a message box telling them so, then it is supposed to clear the text box so the user can try again. But no matter what I try, the text box does not clear it still keeps the last character typed (the invalid one).
Here is the code for one of the text boxes.
Private Sub txtLanIp_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtLanIp.KeyPress
Dim strEmpty As String = ""
If Char.IsDigit(e.KeyChar) = True Or Char.IsPunctuation(e.KeyChar) = True Or Char.IsControl(e.KeyChar) = True Then
'do nothing
[code]....
The commented methods at the bottom are some of the other things ive tried to make this work. The txtLanIp.text.clear() is what ive tried from the beginning. I have also tried setting the text to "", I even created an empty string and set the .Text value to it but no matter what it wont remove that character. I have also tried various trim(), len(), Select() functions, most either give me an 'index out of range error', a 'length cannot be less than zero' error or a general ExceptionOutOfBounds error. I am just tearing my hair out as to why the simple way doesnt work, there is no logical reason why and it gives no error it just doesn't clear the box.
I have also tried moving the validation to a _LostFocus but e.KeyChar isnt a valid method or property for that declaration, which doesn't surprise me but I wanted to try everything.I dont see how it would matter in this case but I am running Windows XP Pro SP3, though I also see the same behavior in Windows 7 64 bit ultimate sp1 and windows 7 64 bit pro.

View 1 RepliesIs it possible to read the GUID from the Assembly without actually loading it in the current App Domain.
Normally Assembly.Load loads the DLL into the app domain. I just want to read the value. The description of the GUID is

' if this project is exposed to COM
<Assembly: Guid("DEDDE61CD-928E-4ACD-8C25-3B8577284819")>
