I'm in need of creation of a web part which takes input from a task list and changes the color of the tasklist based on the data in the task list. Can anyone help me with this problem?
I can write code in visual studio 2005.
My question is how do I take input data from the list?
Sample code here. This should get you started. (source)
using Microsoft.SharePoint;
class SPTest {
public void ReadList() {
// Use using to make sure resources are released properly
using(SPSite oSite = new SPSite(pathToSite)) {
using(SPWeb oWeb = oSite.AllWebs[nameOfWeb]) {
// Alternately you can use oSite.RootWeb if you want to access the main site
SPList oList = oWeb.Lists[listName]; // The display name, ie. "Calendar"
foreach(SPListItem oItem in oList.Items) {
// Access each item in the list...
DateTime startTime = (DateTime)oItem["Start Time"];
// etc....
}
}
}
}
}

I have just started using durable functions and needs some advise for how to do fan out pattern correctly. I have a FTP server where from I read all the files. I want to start an Activity function for each file. As I understand it the orchestrator function will be called everytime an Activity function is being executed. I just want to read the files once. To avoid calling the code that read the files and starts the activity functions multiple times, what is the recommended approach? Is it having an activity function that that add's all the activity functions or is it using the IsReplaying property, or something different?
[FunctionName("OrchestrationMoveFilesToBlob")]
public static async Task<List<string>> RunOrchestrator(
[OrchestrationTrigger] DurableOrchestrationContext context)
{
var outputs = new List<string>();
if (!context.IsReplaying)
{
// Do you call your database here and make a call to CallActivityAsync for each row?
}
// doing it here is properly very wrong as it will be called multiple times
var tasks = new Task<string>[7];
for (int i = 0; i < 7; i++)
{
tasks[i] = context.CallActivityAsync<string>("E2_CopyFileToBlob",""); }
await Task.WhenAll(tasks);
return outputs;
}
When looking into the sample in the link below this actually calls it directly in the orchestrator function? Is this not really bad? It continue adding same activities again and again .... ?

Not sure I understand what you try to achieve but your code looks not bad so far. An orchestration is just called once (and maybe some times more for replay but this is not your problem here). From your orchestration you can call in a fan out all your activity functions (gathering a file from an ftp) each activity function one file. await Task.WhenAll(tasks) is your fan in. (you can use a List<Task> instead of the array and call .Add(task) on it if you want. In order to not edit your code I copied it here and added some comments and questions (feel free to edit here):
[FunctionName("OrchestrationMoveFilesToBlob")]
public static async Task<List<string>> RunOrchestrator(
[OrchestrationTrigger] DurableOrchestrationContext context)
{
var outputs = new List<string>();
if (!context.IsReplaying)
{
// just needed for things that should not happen twice like logging....
}
// if your work isn't a fixed list just call an activity
// which replies with the list of work here (e.g. list of filenames)
var tasks = new Task<string>[7]; // can be a List<Task> too
for (int i = 0; i < 7; i++)
{
tasks[i] = context.CallActivityAsync<string>("E2_CopyFileToBlob","");
}
await Task.WhenAll(tasks);
return outputs; // currently an empty list. What do you want to give back?
}
I'll start by saying i'm a C# MVC newbie, but I've set up a site with Identity Management and extended the database with some custom tables to store additional info about my users, so I'm not a total neophyte. I've been working on a VB WPF application that I want to deploy from my new website and that is where I'm running into an issue.
I've created a new controller (User) and a couple of views (Download) & (Setup). I created a downloadmodel used by the download view.
In abstract what I am doing is displaying the download view (get) which has three checkboxes to confirm the user has read the Overview, Installation, and Terms of Service. These are boolean values in the model. I also have a string response message in the model, that displays just above the submit button. Here is the model:
public class DownloadModel
{
public bool Overview { get; set; }
public bool Installation { get; set; }
public bool TermsOfService { get; set; }
public string Response { get; set; }
public DownloadModel()
{
Overview = false;
Installation = false;
TermsOfService = false;
Response = "After checking boxes click the button to begin installation";
}
}
My User Controller handles the Get to initially display the download view, and then in the Post it checks to see if all the checkboxes were ticked, if not it updates the response message and returns the view.
If the checkboxes are all checked then it pulls the subscriber (which must exist because it was created when the user verified their e-mail via the account controller - identity management), then proceeds to update the subscriber with the original (if new) or last download date(s). At this point I want to begin downloading the clickonce setup.exe file, before returning the setup view.

public class UserController : Controller
{
// GET: User/Download
public ActionResult Download()
{
return View(new DownloadModel { });
}
// Post: User/Download
[HttpPost]
public ActionResult Download(DownloadModel downloadcheck)
{
if (!ModelState.IsValid)
{
return View(downloadcheck);
}
//check to see if all the boxes were checked
if (downloadcheck.Overview == true &
downloadcheck.Installation == true &
downloadcheck.TermsOfService == true)
{
//yes - so let's proceed
//first step is to get the subscriber
Subscriber tSubscriber = new Subscriber();
tSubscriber.Email = User.Identity.Name;
bool okLoad = tSubscriber.LoadByEmail();
if (okLoad == false)
{
//we have a real problem. a user has logged in but they are not yet
//a valid subscriber?
throw new Exception("Subscriber not found");
}
// update subscriber with download in process...
if (tSubscriber.OriginalDownload == DateTime.MinValue)
{
tSubscriber.OriginalDownload = DateTime.Now;
tSubscriber.LastDownload = tSubscriber.OriginalDownload;
}
else
{
tSubscriber.LastDownload = DateTime.Now;
}
if (tSubscriber.UpdateDownloaded() == false)
{
//update of download dates failed
//another problem that shouldnt occur.
downloadcheck.Response = "A problem occured downloading your setup."
+ "Try again. If this error continues please contact support.";
return View(downloadcheck);
}
//download dates have been updated for the subscriber so let's start the download!
//THIS IS WHERE I NEED TO BEGIN THE DOWNLOAD
return View("Setup");
}
else
{
// all boxes were not checked - update message
downloadcheck.Response = "Please confirm you have reviewed the above information "
+ "by checking all of the boxes before clicking on the button.";
return View(downloadcheck);
}
}
}
The download view is pretty straight forward, and the setup view simply confirms the download was started and provides a link to the help-setup page.
I'm really a bit lost here. I thought I'd plug in a return new filepathresponse, but I can't do that and return the setup view.
My other thought was to somehow trigger the download of my /xxx/setup.exe from within the setup view as it is returned - but I'm at a loss as to how to accomplish this.
I'll be the first to admit that my mvc c# code is probably overly verbose and my approach to how I've done this may be totally wrong, but I'm just scrambling to get this done so I can deploy my WPF app to select Beta users for testing. It's been a long time living off savings and I can smell go-live from here.
One final note, I'm using setup.exe clickonce deployment of my wpf app for simplicity, as there are .net and localsqldb prerequisites, but I will not be using automated updates - not that this is really relevant.
Appreciate all input and advice.
After more digging and hacking I've found a solution that works. Firstly in my setup view (confirmation page) I added a simple script to initiate a new function in my user controller:
<script type="text/javascript">
window.location.href = "/user/sendfile/"
</script>
The controller change was simple too. For testing I just used a txt file.
// User/SendFile
public ActionResult SendFile()
{
string path = #"~/xxxx/anyfile.txt";
string content = "application/txt";
//string content = "application/x-ms-application";
return new FilePathResult(path, content)
{
FileDownloadName = "mynewtext.txt"
};
}
What is really interesting about this solution is that the FileDownloadName is what the file content is downloaded as. So in this way I can refer to the actual setup.exe file in the path, but then name the downloaded exe anything I want. Bonus :)
I need to get a list of values asynchronously from the server. The API's method returns a Future.
Of course I can create a callback and assign the result manually, I wonder if there's a way to delegate this to AngularDart?
class IndexPageController {
var apps;
EasyAPIClient api = new EasyAPIClient('/api/');
IndexPageController() {
_loadData();
}
_loadData() {
api.getAppNames().then((app_names){
apps = app_names;
});
}
}
What I'd like to have approximately:
class IndexPageController {
var apps;
EasyAPIClient api = new EasyAPIClient('/api/');
IndexPageController() {
_loadData();
}
_loadData() {
// this code executes successfully,
// however the template never receives the list.
apps = api.getAppNames();
}
}
AngularDart doesn't currently support Futures/Streams in templates.
I'm writing a command line application that checks the SPFieldCollection returned by the SPWeb.Fields property, but it's not behaving as I'd like. I have hundreds of SPWebs and it's definitely touching them all, but for all but the initial SPWeb, it's returning an empty Fields property. What am I doing wrong?
string siteUrl = "http://webroot/sitecoll";
using (SPSite siteCol = new SPSite(siteUrl))
{
using(SPWeb outerWeb = siteCol.OpenWeb())
{
foreach (SPWeb innerWeb in siteCol.AllWebs)
{
LogMessageToFile(String.Format("Checking {0}", innerWeb.Url)); //executed for each of the hundreds of innerWebs
if (innerWeb.Fields.ContainsField("Year"))
{
// Never accessed after the first time through because innerWeb.Fields is empty
}
}
}
}
SPweb.Fields live at the site collection level.
Unless you specifically create the fields at the subsite levels you will get 0 returned.
I have written an add in that takes the active document as a parameter. So each time that the active document has changed, I need to know. To do so, I wanted to use "Events.DocumentEvents.DocumentOpened" event of the DTE2 object. But the problem is that event is never get fired even though I change the active document.
The code snippet is as follows
public void OnConnection(object application, ext_ConnectMode connectMode, object addInInst, ref Array custom)
{
_applicationObject = (DTE2)application;
_applicationObject.Events.DocumentEvents.DocumentOpened += new _dispDocumentEvents_DocumentOpenedEventHandler(DocumentEvents_DocumentOpened);
...
}
void DocumentEvents_DocumentOpened(Document Document)
{
MessageBox.Show("Not called");
}
I have tried with DocumentEvents as well but no success. Any ideas?
I had just realized that I focused on the wrong event and thats why it was not fired. With the code below I got what I intended to. So instead of DocumentEvents, I had to use WindowEvents.
....
_applicationObject.Events.WindowEvents.WindowActivated += new _dispWindowEvents_WindowActivatedEventHandler(WindowEvents_WindowActivated);
}
void WindowEvents_WindowActivated(Window GotFocus, Window LostFocus)
{
if (ucCAST != null && GotFocus.Document != null)
((CAST)ucCAST).refreshCode(GotFocus.Document.Name);
}
