C# - DirectoryInfo And Path.GetDirectoryName - Exists Method Returns False While Exists?

Dec 13, 2010

I would like to check whether a folder exists or not if not create. I'm sure this folder exists, but for some reason I get "false" when I check with "Exists" method.

The only reason I think could be because of the W: drive? I moved this application to production site and even there it returns false.

while I'm type in Windows explorer on my localhost and on the server "W:/Webs/ASPPages/cropper/uploads" it opens this folder. So my localhost and IIS server has W: mapping.

for test I tried to create the folder then it says can't find the path...

userFolderName = @"W:/Webs/ASPPages/cropper/uploads"
//I also tried @"W:WebsASPPagescropperuploads"
//I also tried @"W:WebsASPPagescropperuploads"
//I also tried "W:\Webs\ASPPages\cropper\uploads"
DirectoryInfo dirInfo = new DirectoryInfo(userFolderName);........

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?

C# - Checking If An Item Exists Before Saving?

Feb 2, 2011

I've a SQL DB with various tables that save info about a product (it's for an online shop) and I'm coding in C#. There are options associated with a given product and as mentioned the info recorded about these options is spread across a few tables when saved.Now when I come to edit this product in the CMS I see a list of the existing product options and I can add to that list or delete from it, as you'd expect. When I save the product I need to check if the record already exists and if so update it, if not then save a new record. I'm trying to find an efficient way of doing this. It's very important that I maintain the ID's associated with the product options so clearing them all out each time and re-saving them isn't viable unfortunately.To describe again, possibly more clearly: Imagine I have a collection of options when I load the product, this is loaded into memory and added to / deleted from depending on what the user chooses. When they click 'Save' I need to check what options are updates and what ones are new to the list.

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?

MVC :: "Path" To Linked File - FileInfo.Exists Always False?

Nov 30, 2010

i set up Log4Net in a project, with the Log4Net.config file in "App_Data/config/Log4Net.config", and called the XmlConfigurator.Configure function with the following:

[Code]....

However, I the config file to be available in multiple projects, so moved it out to a solution folder (config/Log4Net.config).

Back in my MVC project, I added the config file as a linked file (and also set it to a "embedded" resource and "copy always" for the heck of it)

However I got no idea how the previous "var configfile = new FileInfo("????")" should read.

Tried it with and without Server.MapPath, using "Log4Net.config", "/Log4Net.config", "~/Log4Net.config", etc. No luck.

My guess it's because this Log4Net.config is not an actual file, but just linked.

Web Forms :: Checking All Checkboxes On The Page Using 1 Checkbox With Or Without Javascript

Nov 1, 2010

I have found plenty of examples where the checkboxes to be checked are within a datalist, gridview or other datacontrol like that.. but i dont have that setup..

I have individual checkboxes within my page and need to provide a way to check or uncheck them all..

I cant use a checkboxlist because of the layout of the page.. so not sure if it would be easiest with javascript or do it with the checked event for the single check box that will be used..

I know that may not be the best or cleanest way, but is there a better way?

Reason i cant use a checkboxlist for the larger set of checkboxes, is that a few of them will have additional fields that need to be completed if they chose certain checkboxes.. so i have those controls next to the checkbox that they belong with..

Javascript - How To Check Whether A Certain Text Box Exists In A Page

Feb 9, 2010

Suppose I have a master page where I have written some javascript to access the value of a particular asp.net text box, which resides in one of its content pages, but not in all the pages. This piece of javascript code can't be moved to that particular content page because of some restrictions.

Now I need a way to determine whether or not that text box exists in the page, which will imply that the content page containing that text box has been loaded.

How I can I do that in javascript?

The problem that I'm having is that when the app is hosted on the staging server, the theSource is mapped incorrectly (contains /ClientSite/). I could do something like a String.Replace but I'm looking for a more elegant way of achieving this.

Javascript - How To Path When Deploying

May 14, 2010

We have moved a lot of images and javascript file that was inside class to external Javascript file. In development (Debug inside Visual Studio), everything look nice, all images show, all javascript works and all CSS display perfectly. When we do a package and install with IIS ina virtual directory everything that is pointed by the JavaScript doesn't work.

Question : Since we cannot use the tilde (~) in javascript or in CSS what is the way to display those resources?

Edit 1

The problem is the website is installed with a Virtual Directory and if we have in the JavaScript file a popup that has a hardcoded path in the JavaScript the code try to display : "http://localhost/NameSpace/Directory/File.html" instead of "http://localhost/VIRTUALDIRECTORY/NameSpace/Directory/File.html". Is there a configuration with IIS or inside the code I need to add something like a parameter to pass the path everytime?

In the javascript in dev it work to have something like :

var popWindowPath = '/ProgressFile/Simple/ProgressSlow.htm';

C# - How To Resolve A Javascript Path For Pages That Have Different Directory Levels

Feb 15, 2011

I have a javacript file (script.js, for example) in the following location:

/Website/Shared/Js/script.js

I have two pages which use this javascript, but each one of them seems to require a different path and I can't figure out how to resolve both of them.

One of them is the page:

/Website/One/Two/Three/page.aspx and this requires the path:
<script src="../../../Shared/Js/script.js" type="text/javascript"></script>

The other page is:

/Website/One/Two/page.aspx and this requires the path:

<script src="../../Shared/Js/script.js" type="text/javascript"></script>

I tried to come from the root by doing

<script src="../Shared/Js/script.js" type="text/javascript"></script>

or

<script src="/Shared/Js/script.js" type="text/javascript"></script>

but none of these seem to work. The temp solution I have found is to declare the script twice which is dumb, but that is all I can think of now.
