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:
"~/FileName"
To
"FileName"

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# - Checking If A Remote File Exists?

Mar 24, 2011

I have a ASP.Net website with links to files stored on a file server. These files are modified constantly and so the links will not always be valid, this includes changes to permissions, files being moved or deleted, etc. I implemented a method in the code-behind to check the validity of these links as they are constructed, if it fails the code will add CSS to change the color of link:

Check URL

/// <summary>
/// Check if a URL exists. Method by http://www.vcskicks.com/check-website.php
/// </summary>
/// <param name="url">URL to validate</param>
/// <returns>True if the URL was resolved, false otherwise</returns>

[Code]....

My problem is that not all the invalid links are getting the style added to them. The strange thing is that when I step through the method in debug mode using one of the bad links that was not colored, the method will return false and color the link as expected. There's a lot more involved then what I present above, but I searched the entire aspx code-behind for any other locations where the link url is being set and couldn't find any. I don't know if there's some post processing going on that somehow clears any styles that were applied to some of the links. The fact that some links are colored while others are not is very confusing to me. Has anyone else encountered similar behavior before?

Commas Not Recognized In File Exists?

Jul 21, 2012

I have a .net aspx project done with VS 2008 using the .Net 2.xxxx framework. This ASPX application is deployed on and 4 different 2003 Server boxes. 3 are running in total beautifully. In the 4th box is my issue. I do a FILE.EXISTS conditional test looking for case file pdf's. These case numbers are structured as such 2012-C-0421,001,0008.PDF

Please note the comma's used in the path. 3 of the 4 servers in court houses recognize the path to the pdf WITH the commas in them perfectly and the FILE.EXISTS works 100%. On the fourth box (same config we THINK) the exact same FILE.EXISTS does not return a hit even though we see the document sitting in the folder via explorer. IF we remove the commas and make it 2012-C-0421001008.pdf all is fine and document is indeed discovered with the EXISTS.

WHY on this one server does the original ducument path not function. We can not ask the court houses to change the way they store their documents so I need to make this work like the other 3. Again... same version..same .net framework... same OS (2003 server)

Jul 29, 2010

I have two websites. One site contains nothing but image files. This is a sub-domain of the main website. The main website allows the user to search a database of information and displays that information. I create a grid with a link to the file. In my row_databound function, I want to check to see if that file exists on my other website. If it doesn't I remove the link, otherwise I leaves a link to that file. how to verify that the LINK actually goes to a file that exists?

Web Forms :: FTP Download - How To Check File Exists

Dec 7, 2010

What is the way to :

1) Check if a file exists on an FTP site.

2) Sample the size of that ftp file (3) times to ensure the file is ready for downloading.

We have some classes doing this already but they are using WebRequestMethods.Ftp.ListDirectoryDetails and then searching there in if file exists. I am hoping there are some clean ways to do this.

C# - File.Exists Using The Wrong Root Path?

Mar 17, 2011

In my c# class I wrote I have a photo property that returns the photo source if the image exists (nothing or default image otherwise). In my code I use:

public string Photo
{
get
{
string source = "~/images/recipes/" + id + ".jpg";
if (File.Exists(source))
return "~/images/recipes/" + id + ".jpg";.......

If I get the FileInfo() information for this image I see that I tries to find this image in the following directory: C:Program Files (x86)Common FilesMicrosoft SharedDevServer10.0~images ecipes Of course the image is not located in that directory and File.Exists is returning me the wrong value.how can I fix this?

WCF / ASMX :: Web Service Not Correctly Using File.Exists()?

May 26, 2010

I have a large web application that uses File.Exists() in a global file utility class flawlessy for several years now. I just built a new ASMX web service that calls that same method in our file utility class, and it returns False for the same exact file paths that are being passed in the web application. The paths are absolute system file paths, and they match on both the web service and the web app.I am confused... Why might this happen? The method I am talking about is only a few lines of code. A couple of lines simply validate the file id parameter being sent into the method. The last remaining line is this:

[Code]....

The previous line of code calls another method that uses a String.Format to insert the file id into the file path. That's it.

How To Check If File / Software Exists On Client Machine

Jan 6, 2010

I'm having some trouble trying to create a page for my web app. I'm not trying to write a simple download/upload page. Should also say that I'm not trying to write a complex one.What I need to do is in the PageLoad check if the user has installed one particular software and then show the right message to download and install OR run it from the user's actual installation. For this scenario I've tried to use different file upload controls to check if the file was on the client machine, but none of then can do this, since, for security reasons,I can't programmatically set the path and file to upload.
