Am developing a module for DotNetNuke 7. I want to be able to upload a thumbnail image for entries in a catalogue. Have managed place control in edit view of my module and upload and select files however when I build the project I get the following error:
C:\dnn\dotnetnuke\DesktopModules\EventCatalog\Edit.ascx.designer.cs(103,38,103,41): error CS0234: The type or namespace name 'Web' does not exist in the namespace 'DotNetNuke' (are you missing an assembly reference?)
Also I can't figure out how to get the selected file on the backend to save the url to database. When I enter the ID of the control VS recognizes it but intellisense doesn't provide any clues as possible options.
Can anyone tell me how to fix the above error and also if possible, point me towards a overview/tutorial for this control. Have done a fair amount of Googling but not found anything.
Well, to start, you probably need to add an assembly reference to DotNetNuke.Web to your project. Once that's there, it'll probably help with your lack of intellisense as well.
Looks like the main way you interact with the selected URL is via the FileID property. The control itself will manage saving the file to the selected FolderPath (which may or may not be something the user can change).
But, you're right, there aren't good resources for how to use the control. The best "tutorial" it probably looking through the DotNetNuke core code to see how the core uses the control.
The built in dnn upload control is specifically designed for uploading files to the dnn file system - but to be honest its pretty ugly to work with.
It makes a lot of assumptions about what you want to do with the file and as part of its process automatically registers new file in the dnn file system index.
Its also not really ideal for thumbnail uploads or any such fancy stuff - since it has no capability for file size management or scaling and cropping - its something that has been promised a couple of times but not eventuated to date.
On top of this is has a bit of a mind of its own when it comes to where it actually stores the uploaded file - which means you may be better off looking at a 3rd party uploader that you can control more easily.
FWIW - there is a full version of the telerik asyn upload library installed with every dnn install - you will need to setup it up manually but that is not that hard.
<dnn:DnnAsyncUpload></dnn:DnnAsyncUpload> is the markup basic structure and its functionally equivalent to <telerik:RadAsyncUpload></telerik:RadAsyncUpload>
Its documented here http://www.telerik.com/help/aspnet-ajax/asyncupload-overview.html
Having said all this if you do want to stick with dnn file picker - this code will let you find the file object that dnn uploaded the file too.
String thisURL = "";
String thisPHYSICAL = "";
Int32 itest001 = thisControl001.FileID;
if ( itest001 > 0 )
{
var thisFILE = (DotNetNuke.Services.FileSystem.FileInfo)FileManager.Instance.GetFile(itest001);
thisURL = FileManager.Instance.GetUrl(thisFILE );
thisPHYSICAL = thisURL.PhysicalPath;
}
thisURL will contain a url relative to your website domain
thisPHYSICAL will contain the physical location of the file on your server.

I have a client that want's me to make a change to her OTHER site. The other site was built using Dreamweaver.
I guess (I don't build using Dreamweaver) the site pages are being controlled by the template file EXCEPT for the content that is specific to the page.
So I need to change the navigation items.
I found a folder called templates and in that folder is the template.dwt file. I tried copying that file to my desktop, then making the change and uploading back to the ftp site. Of course that had no effect on the nav items. My guess is the file on my desktop does not know to update the other pages as it doesn't know where those pages are.
So how do I go about making the changes to the files on the ftp site using the DWT file?
Do I have to download ALL the html files and the DWT files and somehow create a relationship so when I make the change to the DWT file it updates all the pages on my desktop THEN re-upload all those files back to the ftp site?
Thanks
My guess is that you already figured this out, but just to be sure. You're question is right, the DW template works by when the template is modified (in DW) then you can update all the pages that are linked to it.
If you take the template out of DW and just modify and upload that alone, then nothing will happen to the other pages. So yea, if you know a way to create a link between the template and the other files outside of DW, then that is what you need to do. The other option is using DW and modify the template and then update the other pages, which is done in a semi-automatic way. Semi-automatic, meaning that DW gives the option to update the files either once you save the template or you can save the template and update the files later using DW.
And your guess is correct, the template modifies areas that are not specific to a page. Usually, this is done by creating Editable Regions in the template. Those regions are excluded from change when the template is modified.
You have to create a project in DW and put inside all the files that are "linked" with the template. They usually have tags inside that refer to the template.
Make sure that you keep the same file and folder distribution that the original had. If not, you could have a mess with relative links.
Then, with your template also in the project, open and modify it.
When you save the template, DW will ask you for scan and update related files, if you are lucky it will find and update all of them.
I am wondering if there is some way to change where CKEditor looks for images. Right now it uses the location of the web page containing the editor as the root directory but I would like to write a javascript function that can change this directory to any arbitrary path passed to the function.
The bigger picture for this is that I'd like to extend the functionality of CKEditor to be able to save the source it creates to whatever location is picked by the user. I've already implemented getting the source and saving it using wxWidgets but am having trouble getting CKEditor to change its working directory so that images can be included from the directory the user picks.
I've tried using some of the properties like baseDir, basePath, and baseHref to make this possible but as far as I can tell none of them quite do what I'm looking for.
So the process would be:
(1) The user picks a directory where the source will be saved
(2) The user creates a page using CKEditor where images from the directory chosen can be included AND DISPLAYED in CKEditor
(3) The user saves the source of their page to the chosen directory (the source saved here should use the relative path to the images because the source is now located in the same directory as the images it includes)
I realize this is a rather unconventional use of CKEditor but if someone might be able to kick me in the right direction to making this happen, I'd really appreciate it.
EDIT:
So after a little experimenting and changing some backslashes to regular slashes, it looks like the baseHref attribute does what I'd like. I've still not been able to change its value at runtime though as I would like. Does anybody know if this is possible with CKEditor? I'd still like to have a javascript function that I can pass a path to and have it change this baseHref value. Right now I have set its value in config.js.
If this isn't possible, I know you can read and write the source in and out of the editor. So I would like to resort to reading and storing the source from the editor, reloading CKEditor with a new config.baseHref, and then writing the source back into the editor. Does anyone know if the CKEditor api provides functionality to reload its configuration?
Thanks.
I don't expect too many people will be trying to do what I was doing here since CKEditor is usually hosted on a server somewhere, but in case someone finds it helpful, here's what I ended up doing.
As I mentioned in the edit to my question, modifying the baseHref gave me the functionality of prepending the image filename with the directory path leading to it. I wasn't able to find a way to modify it while the editor was running so I ended up telling CKEditor to load an external configuration file each time it started with the line
config.customConfig = 'C:/Users/kenwood/Desktop/MarkCreator2/ckeditor/custom_config.js';
Then I used C++ to write new contents to custom_config.js any time I wanted to switch directories.
Unfortunately this method meant I had to read the contents out of the editor, refresh the page, and then write the editor contents back in any time I wanted to change directories. This was adequate for what I needed though.
Summary of Solutons: The core issue was that I had my resx files in subfolders within App_LocalResources and App_GlobalResources. Separating things into folders is fine on .NET but Mono only looks at the files in those folders ignoring any sub folders.
Issue #2 works only at runtime. In other words the Resources namespace can be used in the aspx or in code in a script block in the page but not in the code behind. It seems that I've never used the Resources namespace in the code-behind proper so all 3 of my issues are solved.
I have an ASP.NET application I was previously working on on .NET on a PC and am trying to move over to a Mac to develop using Mono and MonoDevelop. The application utilizes the App_GlobalResources and App_LocalResources folders. The application worked on .NET but does not function properly on Mono as I will outline. The version information is below:
OS: Mac OS 10.8.2
Mono: 2.10.9
ASP.NET: 4.0.30319.1
MonoDevelop: 3.0.5
I've tagged this with MonoDevelop because I'm not sure what server is being used and whether it is a part of MonoDevelop or Mono itself or is separate. I'm not familiar enough yet with Mono and it's parts...
The issues I'm having revolve around accessing resources and I'm having various related issues which I'll outline below:
Issue 1: meta:resourcekey doesn't work and "a resource object was not found at the specified virtualPath." error
I have App_LocalResources folders and resx files for each page at the root of the application as well as in sub-folders where page localization is required. Elements on the page that have a meta:resourcekey attribute do not have the relevant property assigned the value in the resx file.
So for example I have: /Site/Home.aspx with a /Site/App_LocalResources/Home folder which contains home.aspx.resx and related translations
N.B. as I was writing this I realised the names don't match up with regards the files case, but that is not the issue, I've tested with another page in the same folder and it doesn't render out the resource values.
The page in question has no code behind.
A different page in the root of the application called PageNotFound.aspx has related resx files in /App_LocalResources/PageNotFound/PageNotFound.aspx.resx
This page content is basically as follows (if I remove both the page renders)
<h2><asp:Literal runat="server" meta:resourcekey="PageNotFound" /></h2>
<% string message = GetLocalResourceObject("Sorry.Template").ToString(); %>
I get the same error whether I remove the first or the second of these lines. The error starts:
System.Resources.MissingManifestResourceException: A resource object was not
found at the specified virtualPath at
System.Web.Compilation.DefaultResourceProvider.GetLocalResourcesAssembly
If I remove the first line is actually builds and tries to render the page but crashes giving the above error.
If I remove the second line I get the error as well but it is while the page is being parsed and the runtime is trying to build the page class.
So for one page is seems build and run with meta:resourcekey attributes but isn't binding the resource value to the properties of the underlying controls, on another page it seems to crash trying to access the resources. The odd thing is the page that crashes is a very simple page without a master page and it basically only has the above content, the other page is quite complex with a master page and it renders (i.e. no parser error) but without the resourcekey values assigned....
The only differences that I can see are that one page is in the root directory and no master page, the other is in a sub folder and has a master page? Go figure! Any ideas?
Issue 2: Resources namespace doesn't exist
If I access a page that uses the 'Resources' namespaces that is available in .NET, I get a runtime compilation error, as in the app builds when compiled, but as the page is parsed and compiled it causes a (runtime) exception...
Compilation Error: CS0103: The name 'Resources' does not exist in the current context
The code would be in the code behind: (EDIT: The following line I think, was me testing, my code never uses this namespace in a code behind (compile time) class. Once the global resources functioned then the namespaces worked at runtime, but not in scenarios where the namespace needs to be verified at compile time as outlined in the summary at the top of the question)
msg.Subject = Resources.EmailResources.Request_SubjectLine
or in a script block in the aspx itself i.e.
<%= Resources.EmailResources.Request_SubjectLine %>
Neither of these types of access to the Resources namespace work. Why does this not work in Mono. Does the Mono framework not generate this stuff for us like .NET does? (I'm fairly sure this namespace hierarchy is generated by the ASP.NET framework on .NET and therefore wonder if this just has not been implemented in Mono?)
Issue 3: GetGlobalResourceObject(...) Call Returns Null
In the code-behind I have calls to GetGlobalResourceObject() which works on .NET, but when I run it on Mono my code is throwing an exception. For example:
hlContact.Text = GetGlobalResourceObject("CommonResources", "Contact").ToString();
My folder structures is:
App_GlobalResources > CommonResources > CommonResources.resx and the designer file (CommonResources.Designer.cs) is there.
The resx files are all marked with build action of "EmbeddedResource", "Do not copy" use the Custom Tool "GlobalResourceProxyGenerator" and have a resource ID that makes sense for each file. (i.e. .App_GlobalResources.CommonResources)
The issue is that GetGlobalResourceObject() returns null... It's not finding the CommonResources resource....
Note that Mono is constructing '*.resource' files in the folder with the resx files.
Issue #1
Apparently mono doesn't search subdirectories for resources, that is you must keep them directly in App_LocalResources or App_GlobalResources. See the relevant part in the mono source code (line 134). If searching subdirectories is an official feature, then this is a bug, and can be easily fixed by changing the aforementioned line.
Issue #2
Works fine here (on linux).
Issue #3
I don't know how exactly you are embedding the resources, a small test project would help. For the App_GlobalResources the framework compiles them at runtime and then GetGlobalResourceObject works fine too.
I've been working on a Windows Phone 7 app, and after a bit of Googling it seems that for images that I have added to the Visual Studio project, I need to set the build action to "Content" in order to be able to reference the images in my app.
However, the Windows Phone List Application project template includes an image (ArrowImg.png) that has its Build Action set to "Resource", and is still available to be referenced from the application.
I was wondering if anyone could confirm that we should definitely be using the Content build action, or whether there is some way to access images added to a project with the Resource Build Action as shown in the project sample, which we should be using instead?
If you set the action to "Content" the image is included "as-is" in the XAP.
If you set the action to "Resource" the image is embedded into a shared DLL.
In a lot of situations you can use either. There may be a performance, or other, issue with using one rather than another but I'm not aware of and have never noticed any.
For what it's worth, unless I need to specifically make it a resource, I use content.
With the current (Beta) tools, I have seen VS complain that images directly referenced in XAML should be set to "Resource" (if set to "Content") but the app works fine with either. Hopefully this is an issue which will be addressed in the RTM tools.
For more information see the discussion in What are the various "Build action" settings in Visual Studio project properties and what do they do?
Either build action is correct.
Also worth looking at when resolving issues relating to build action is the pathing you use.
I've seen a fair few people running into trouble with this because they assume they've set their build action inappropriately.
You can set the build action either way to suit your requirements of when to incur the load time cost, you just need to adjust the pathing to suit.
Some more info on the topic from this post.
Set source to image in C#
You can liken content to the lazy
loading version of resources.
The difference is you will incur the
performance hit of all resources when
the assemblies are loaded to start
your app.
Content, on the other hand, the
performance hit is deferred to when
you use it.
Which is more suitable will vary on a
case by case basis.
Note also that the pathing to
reference resources and content is
different as can see here.
//Uri uri = new Uri("/Resources/Images/MyImage.jpg", UriKind.Relative); // Content
Uri uri = new Uri("/PhoneApp;component/Resources/Images/MyImage.jpg", UriKind.Relative); // Resource
BitmapImage imgSource = new BitmapImage(uri);
image1.Source = imgSource;
In a visual studio project I have three layers, Data Layer, Business Layer and Presentation Layer.
In the Data Layer I have a few XSLT's that transform some objects into an email, all works fine but I have discovered that the XSLTs do not get built/copied when building.
I have currently, created a folder in the deploy location and placed the XSLT's there but I am concerned about relying on a manual process to update these.
Has anyone encountered a similar issue and if so how did they get around it.
It smacks of changing the MSBuild script to copy the build artifacts to the required location, does anyone have examples of this?

If you are using Visual Studio 2005/2008, the easiest way to do this is by including your XSLT files as project resources.
Open the Properties for your project.
Select the Resources tab. You will probably see a link that says "This project does not contain a default resources file. Click here to create one." Go ahead and click on that.
Click the Add Resource drop-down near the top and select Add Existing File.
Browse to your XSLT files and select them.
After you have done this, you can easily access the resources in the following manner:
// To get the contents of the resource as a string:
string xslt = global::MyNamespace.Properties.Resources.MyXsltFile;
// To get a Stream containing the resource:
Stream xsltStream = global::MyNamespace.Properties.Resources.ResourceManager.GetStream("MyXsltFile");
If you are using Visual Studio 2003, your best bet is to include those XSLT files as embedded resources for the DLL. In Visual Studio, select the file(s) in Solution Explorer, open the Properties pane, and change the Build Type to "Embedded Resource". You can then use the GetManifestResourceStream method to get a Stream containing the XSLT(s). The name to pass will be based on the default namespace of your assembly, the folder containing the file, and the name of the file.
For example, say your data layer assembly has a default namespace of My.DataLayer. Within your data layer project you have a folder named Templates which contains a file called Transform.xslt. The code to get your XSLT would look like this:
// There are numerous ways to get a reference to the Assembly ... this way works
// when called from a class that is in your data layer. Have a look also at the
// static methods available on the Assembly class.
System.Reflection.Assembly assembly = (GetType()).Assembly;
System.IO.Stream xsltStream = assembly.GetManifestResourceStream("My.DataLayer.Templates.Transform.xslt");
For more information check out this article on CodeProject.
Obvious question maybe, but still has to be asked, did you include the folder containing the XSLT's in the project itself? Is this a web or forms app?
In VS, it is easy to set the properties of the XSLT files in the project to copy on build, by default they do not.
I may have explained myself poorly.
THe Data layer is a class library that a the presentation layer references.
On building the DataLayer I can get the XSLTs to output to the Bin directory of the DataLayer. However when I build and publish the presentation layer, it correctly grabs the DLL but not the XSLTs
