Web Forms :: Display File Is Locked Error Message When File Is Used By Another User

May 7, 2015

after i can copy my file to another folder i realised that if this webapplication is used by multiple users at once, then some users are going to get locked out because each one is trying to copy those files.

so how do i tell the user thats trying to use a file to wait untill the file is available.

StreamWriter WriterTotxt = new StreamWriter("date.txt", false);
DateTime LastAccess = File.GetLastWriteTime("path.dbf");
string ReadTextFile = File.ReadAllText(txtFile);
DateTime test = Convert.ToDateTime(ReadTextFile);
if (File.GetLastWriteTime(LatestUpdatedTime).CompareTo(test) > 0)
File.Copy(Path.Combine(sourcefile, fName), Path.Combine(destinationfile, fName), true);

Display Asp MSChart / File Error Could Not Load File Or Assembly 'sstchur.web.survey'?

Dec 17, 2010

I've add MSChart to a webpage and I'm also using a Survey page I got from 4GuysFromRolla (http://www.4guysfromrolla.com/articles/061604-1.aspx). Both work on my development machine but when I move them to my hosting site there are issues.

With MSChart page the chart is not displayed although it's included the Page Source code:
src="/ClubInformationTracking/ChartImg.axd?i=chart_3d90c53b0f844807a2491a1d79a636a1_0.png&g=75fecf0f14cf4121b623691d383263aa" alt="" style="height:300px;width:700px;border-width:0px;" />

And when I try to open the Survey page I get this:Parser Error Message: Could not load file or assembly 'sstchur.web.survey' or one of its dependencies. The system cannot find the file specified.

Source Error:
<%@ Register TagPrefix = "sstchur" Namespace = "sstchur.web.survey" Assembly = "sstchur.web.survey" %>
<%@ Page Language = "C#" %>

Assembly Load Trace: The following information can be helpful to determine why the assembly 'sstchur.web.survey' could not be loaded.

WRN: Assembly binding logging is turned OFF.To enable assembly bind failure logging, set the registry value [HKLMSoftwareMicrosoftFusion!EnableLog] (DWORD) to 1.

Note: There is some performance penalty associated with assembly bind failure logging.To turn this feature off, remove the registry value [HKLMSoftwareMicrosoftFusion!EnableLog].

The Hosting site is using Version 4.0 and the dll needed for the survey is in the BIN directory.

When I moved my files to the hosting site I had to change every instance when I referred to a file from:

I've tried all of the "fixes" I could find for the MSChart that involved changes to the web.config file but because of the error messages associated with the Survey page I'm guessing this is the issue.

C# - Xval Get Error Message From Resource File?

Apr 29, 2010

I'm working on a CMS system which uses a resource file to get information and errormessages from. The client side validation is working without problems, only it's not getting the errormessage from the resource file. While debugging i figured out xval seems to get the errormessages from a javascript file where the messages are set hard-coded. Is there some way to override this?

Below the code which should make the relation to the resourcefile en specify the error when the field is left empty.

[Required(ErrorMessageResourceType = typeof(CMSMessages), ErrorMessageResourceName = "EnterValidMoney")]
public virtual Double ShippingCost { get; set; }

I have a web page in my project that views a selected pdf file. The problem is the file stays locked with the process w3wp.exe which I assume is the adobe file reader or something. How I can release this process after viewing it? Or another way of viewing it without locking the file?

Here is how I am doing it:

Dim R1 As String = Page.Request.QueryString("r")
If R1 <> "" Then
Dim path As String = File1 & R1

Validation Controls Error Message From Resource File And Parametrized?

I would like to get validation messages for validation controls from resource files. I know I can do that easily by following code snippet.

<%$ Resources:[filename prefix,]resource-key %>


<asp:Label ID="Label1" runat="server" meta:resourcekey="resource-key-prefix" />

But I would also like to parameterized it.


Above Resource Expression will give me message like "Fill Information.". What I have in resource file is "Fill {0} Information." which should show end user message like "Fill Address Information.".

Asp.net - Error Message: Could Not Load File Or Assembly 'Delete ReportingContents'?

Aug 24, 2010

I've just got an error message that was somewhat unexpected:


I've got an ASP.NET website that has abotu 10 projects makign it up which are compiled into DLLS and in the bin directory. ReportingContents is one of these projects. In the past I have had success in copying over a new version of the files (dll, pdb and xml) to the bin directory and recycled the app pool and it just picks up the new version on its own. This time I thought "I shouldn't have a debug version on the site" so I built as release and just copied up the dll and xml files and asked our deployment people to remove the pdb.When I was told it was all done I tried to access the site and got the above error message.The thing that surprises me is that the assembly it mentions is "Delete ReportingContents" and I don't know where the "Delete " might have come from in there.

Version Information: Microsoft .NET Framework Version:2.0.50727.4952; ASP.NET Version:2.0.50727.4927

All of the following have been tried over and over again:

1.) Delete all existing .dlls

2.) Delete MasterPage File and recreate it.

3.) Delete MasterPage perform a clean rebuild then recreate

4.) Delete web.config file and recreate

5.) Delete web.config file perform a clean rebuild then recreate

6.) Destroy the entire project and start from scratch

7.) Before any of these steps were taken the project was built with Ctrl+Shift+B and again with F5

8.) Checked all of the namespaces to make sure nothing was conflicting

9.) Checked IIS7 to see which .NET Framework was being used and it is all listed under 2.0 and later at one point even trying to swithc it over to .NET 4.0

The problem is rather persistant, annoying, and frustrating and I would truly love to acquire some input on correcting this matter,issue occured out of the blue one minute working the next minute it errors out.

DataSource Controls :: Excel File Being Locked - Way To Unlocked It

Jun 14, 2010

I have a page where users can upload an excel file and it is read into our system. I am using the Jet.OLEDB.4.0 provider to read the files. I access the file one time to read out the header names and then allow the user to select which field each column will be read into on import. For some reason after this read the file is locked and the next time I try to access it to do the data import I get the "File in use" message. Each time I open a connection it is closed so I am not sure why the file is being locked.
