I have a table in a database that contains all kind of attachments, images, pdf, excel, and other formats. creating an application is not an option, so I googled other options and I found this related question that mentioned LINQPad I downloaded it but I still do not know how exactly it works. Anyone please explain that to me? I can query the attachments using sql query but not sure how to dump them and preview them via the mentioned tools.
Following on from Dan's answer, once you have the data context set up you can dump the images from the database. I use this snippet for checking an image I've written to the database, you should be able to edit as required to match your scenario:-
var ii = ItemImages.Where (v => v.Id == 10).FirstOrDefault();
using (var ms = new MemoryStream(ii.Image.ToArray()))
{
System.Drawing.Image.FromStream(ms).Dump();
}
Use the Util.Image built in utility for images.
Ex:
var personPictures = PictureTable.Take(1);
Util.Image(personPictures.First().Picture).Dump();
Util.Image takes a byte array.
Depending on your database of your choice, most likely you'll need a data context driver

Once you establish a connection you can start writing queries against the data

I want to query an EmbeddedSolrServer instance with a Filter query. Like we normally do in the picture with an admin panel. But the problem here is that I want to do this programmatically with Java. I know that we can do that query.setQuery("*:*"); , but this is not what I want if someone want to search by a specific word in content's document. I found also this solrParams.add(CommonParams.QT, "*:*");, But it's not working. I think that may be the problem is from parsing the PDF document, when I try to index it. So please if someone know how to index a document using EmbeddedSolrServer exactly the same way we index it using post.jar in command.
Indexing a file is as easy as
EmbeddedSolrServer server = new EmbeddedSolrServer(solrHome, defaultCoreName)
ContentStreamUpdateRequest req = new ContentStreamUpdateRequest("/update/extract");
req.addFile(fileToIndex, "application/octet-stream");
req.setParam("commit", "true");
req.setParam("literal.id", id);
NamedList<Object> namedList = server.request(req);
server.close();
I'm newbie in ColdFusion.
I have a running ColdFusion website I'd like to update. I've copy the database to make some test, in the ColdFusion manager I have created a new datasource with the copied database. But now how can I tell my website that it need to use the copied database?
Thanks
Look in your code and find any cfquery tags and make sure they are using the new dsn in the datasource attribute. Depending on how the code is written, there may be a global variable that holds the dsn and you can just change it there.
Now that you have a test database, you probably want to use conditional logic to determine which one to use. Here is an example from one of my files.
<cfscript>
if (cgi.path_info contains "dwtest") {
dsn = "AntibioticsTest";
} else {
dsn = "Antibiotics";
}
</cfscript>
<cfquery name="GetLastInsertDates" datasource="#dsn#">
sql not relevent
</cfquery>
As mentioned in jhinkley's answer, this variable might be a global variable in which case it's most likely found in Application.cfc.
I need to develop an application that extracts all the contents in Content Tab of the Ektron Workarea and I have to keep tree structure of folders (taxonomies,collections,forms,etc.) also.When I click the content I need to get the Content ID in the code behind also.I need to do all these in a single function.
I tried this requirement with the concept of content block widget in workarea.When we drag that widget and edit it a pop up will come and it displays the folders of work area in tree structure.But when I created an aspx page, put the same code and I browse that page I didn't get the tree structure of all contents.Only the main tabs(Folders,Taxonomies and search ) are visible.Then I drag the user control in the aspx page .But it also doest work.
So how will I solve the above problem.
Can I pull all the contents in tree structure from work area from the root using API codes?.Then can anyone please give the API code to solve?
Please anyone reply!
Assuming you are using 8.6 look here to start with:
http://reference.ektron.com/developer/framework/content/contentmanager/getlist.aspx
Update:
I think I misread your question the first time around. Allow me to expand on my answer a bit. My original answer with the web services assumes that you are rendering the content tree from some sort of "presentation tier" -- a different web site, a console app, or a WPF/WinForms app, etc.
You can get the recursive folder structure with something like this:
private FolderData GetFolderWithChildren(long folderId)
{
var folderApi = new Ektron.Cms.API.Folder();
var folderData = folderApi.GetFolder(folderId);
// This next method is marked as obsolete in v9.0;
// a newer overload is available in v9.0, but I
// don't know if it's available in v8.0
folderData.ChildFolders = folderApi.GetChildFolders(folderId, true);
}
I'm a little confused as to what exactly you're trying to accomplish. If you want to show the entire tree structure graphically, have you tried taking the code and markup from the edit view of the content widget and using it on your non-edit view?
I must say, your requirement that "I need to do all these in a single function" worries me a bit. Workarea content trees can get really large very quickly. If you're trying to load all of the folders and all the taxonomies and all the collections, etc. Then the user will likely be waiting a long time for the page to load, and you risk running into timeout issues.
-- Original Answer --
Ektron v8.0 doesn't have the 3-tier option, which is too bad because that would really make your job a lot easier. In v8.0, there are ASMX web services that you can reference, including:
/workarea/webservices/content.asmx
/workarea/webservices/webserviceapi/user/user.asmx
There are lots more than this; browse through the folders within /workarea/ to see what's available.
It's been a while since I've worked with these services, so I'm a little rusty...
Suppose you add references to those two services I listed above and name them ContentService and UserService. The first thing you'll want to do is set the authentication headers. Then you can call the service methods in much the same way as the old legacy apis.
var contentApi = new ContentService.Content();
contentApi.AuthenticationHeaderValue = new ContentService.AuthenticationHeader();
contentApi.AuthenticationHeaderValue.Username = username;
contentApi.AuthenticationHeaderValue.Password = password;
contentApi.AuthenticationHeaderValue.Domain = domain;
var userApi = new UserService.User();
userApi.AuthenticationHeaderValue = new UserService.AuthenticationHeader();
userApi.AuthenticationHeaderValue.Username = username;
userApi.AuthenticationHeaderValue.Password = password;
userApi.AuthenticationHeaderValue.Domain = domain;
var ud = userApi.GetUserbyUsername("jimmy456");
long folderID = 85;
bool recursive = true;
ContentData[] folderContent = contentApi.GetChildContent(folderID, recursive, "content_id");
I have a php script (ini.php), that open in an iframe inside of "main.php":
<iframe src='ini.php' style='width:650px;' frameborder='0' id="IDMain" allowtransparency="YES" scrolling="NO"></iframe>
The SQL does not retrieve the data in "ini.php".
But if I incorporate the code of "ini.php" in "main.php", without using an iframe, the query retrieves all the information.
I must have an iframe in order to change all the different scripts in the same iframe.
Any help here?
Thanks
In addition more information:
The main.php is in session after logged. Previously I had the whole frame repeated in each script, and everything was ok.main.php, ini.php, and so on. Each script with header, left, right, main and footer. To make it faster and easier I decide to make the main script called main.php, that with an included script called config.inc.php that has several functions, also connects to data base, to retrieve some data to the header, left , right and footer sides of the main area (iframe) where the others different scripts, just to opens inside of a iframe, maintaining the information around. Each script, (like ini.php), that runs in the iframe also include the config.inc.php file, to connect as well to database. But does not retrieve any information
The connection to database in config script is:
<$connect=mysql_connect ("localhost","database","password") or die ('I cannot connect to the database because: ' . mysql_error());
mysql_select_db ("database", $connect) or die ("'I cannot connect to the database "); >
The query in ini,php (and others) is:
`
if ($id) {
$id_session=$_SESSION['id_session'];
$namesession=$_SESSION['name_session'];
$sql="select * from data where id='$id_sessino' limit 1 ";
$result=mysql_db_query("database",$sql);
$regist=mysql_fetch_array($result);
$id=$regist["id"];
$id_session=$regist["id"];
$namesession=$regist["name_session"];
$country=$regist["country"];
And soo on…
}
`
I hope with is information it makes it clear what do I mean. Thank you
Check PHP help for mysql_db_query. Since you are not giving it any open db link, it tries to do some default magic, which likely fails, because, as I mentioned in the comment, the two scripts (in parent window and inside the iframe) are run separately and have no idea about each other *unless you are doing some synchronizing, that isn't shown in the code snippets. That means that the iframe script doesn't know anything about the connection you've opened in the parent page, and fails. Check your logs, you should see some E_WARNING complaints (if you are logging this level).
Also, as the documentation says, you might be better off with MySQLi or PDO_MySQL extensions. But the principle will remain the same - the script in questoin has to have an open connection to the database (and I'm not sure whether you can easily and safely transfer an open from one script to the other one, so you'll likely have to do it all in the iframe script).
Try two things, first I would change the MySQL_fetch_array part to
While($regist = mysql_fetch_array($result))
{
//Code goes here
}
Secondly try referring to the array vales as numbers rather than names, so regist['id'] would become regist[0]. They will be in the order the are in the database.
Also since you select your database when creating connection why not just use mysql_query("QUERY HERE"); Rather than mysql_db_query
I was thinking about giving end users the ability to drop Partial Views (controls) into the information being stored in the database. Is there a way to execute a string I get from the database as part of the Razor view?
Update (I forgot all about this)
I had asked this question previously (which lead me to create RazorEngine) Pulling a View from a database rather than a file
I know of at least two: RazorEngine, MvcMailer
I have a bias towards RazorEngine as it's one that I've worked on but I have a much simpler one at Github called RazorSharp (though it only supports c#)
These are all pretty easy to use.
RazorEngine:
string result = RazorEngine.Razor.Parse(razorTemplate, new { Name = "World" });
MvcMailer
I haven't used this one so I can't help.
RazorSharp
RazorSharp also supports master pages.
string result = RazorSharp.Razor.Parse(new { Name = "World" },
razorTemplate,
masterTemplate); //master template not required
Neither RazorSharp, nor RazorEngine support any of the Mvc helpers such as Html and Url. Since these libraries are supposed to exist outside of Mvc and thus require more work to get them to work with those helpers. I can't say anything about MvcMailer but I suspect the situation is the same.
Hope these help.
