Hi, I am new to the OData World - I am researching, I have been given a task to connect to OData Services they have, they are exposing their Data through OData - that's what I understood, based upon that I have to write an ASP.Net client application, they have given URLs to connect to their OData Services, now I want to understand couple of things before I start writing my client app.
1. What's the use of exposing Data as OData over other web/rest services, why do we need it? Are there any security advantages?
2. What are the best ways to connect to OData Service from client like Entity Framework is better or just use .Net C#?
3. What precautions should I take when I am connecting and using a OData Service?
4. Any other suggestions you can give me would be very very appreciated - thanks a lot. I am also researching about it, but if you know something already also would be helpful - thanks again.

I am trying to apply filters from one dropdown in a datagrid to another dropdown in the same datagrid and same row. The "edit" screen shot is the most important.
The dropdown under "Chamber" will be used to filter the values in the "District" dropdown. Basically, the "Districts" are tied to a "Chamber". I am having a lot of trouble because of the EditItemTemplate sections.
Thank you for the help in advance!

I have a web application based in aspnet 4.5 that is running on a Windows 2016 Server with IIS 10. The app allows to client the downloading of several documents (img, pdf, zip files). All works correctly from several years but starting from 4 weeks to now ios based client (ipad and iphone running 13.3 ios) receive corrupted files. Looking at the logs I have seen that the client closes the connection abnormaly.
this is the code snippets i use to send files:
Response.Clear();
System.IO.FileInfo fInfo = new System.IO.FileInfo(allegatizipfilename);
Response.AddHeader("Content-Length", fInfo.Length.ToString());
Response.AddHeader("Content-disposition", "attachment; filename=allegati.zip");
Response.ContentType = "application/octet-stream";
Response.TransmitFile(allegatizipfilename);
Response.Flush();
Response.End();
I have tried to disable http2, to allow longer connection time, to reduce the minimal connection speed all with no results.
What is strange to me is the fact that anything worked fine till some week ago and nothing was changed in the server configuration nor the software code.
Anyone has the same issue ?

If it's presented as a standard download it might well be a header or CORS issue.
If it's an async download, the error likely lies in the javascript running in the browser.
Determine the download method, check the crapple browser API, and play "spot the difference".

Thanks for your reply,
I will investigate over the things you suggest
But the very strange thing is that the same server configuration worked up to 4 weeks ago and everything is working well in Android or windows
Also we tried several browser as an alternative to Safari, all getting the same results... Is there in your opinion a chance of a bug in ios?

A lot of configurations, such as what encryption standards are acceptable, can be configured at the OS level; it's possible that they locked it down further. The odds of that serious a bug in something as well traversed as the network stack are unlikely.
Can you get wireshark on a client and see what's happening? That would allow you to troubleshoot the TLS handshake, and the overall traffic flow in general.

It was simpler: ios Doesn't accepts octet-streams mime type...

Ah, ignoring the standard. There's a shock.

Hi,
Breaking my head, over this error, for which the reason according to all google results I have been able to find, is usually a simple omission of SelectCommandType="StoredProcedure", or some simple typo.
If this is the case for me, I am just not seeing it.
<asp:ListView ID="ListViewOrderRow"
runat="server"
DataKeyNames="rowguid"
DataSourceID="SqlDataSource1"
OnDataBound="ListViewOrderRow_DataBound">

<asp:Label ID="auf_trnrLabel" runat="server" Text='and lots more stuff like this'></asp:Label>
</asp:ListView>
<asp:SqlDataSource ID="SqlDataSource1"
runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionStringFDS %>"
ProviderName="<%$ ConnectionStrings:ConnectionStringFDS.ProviderName %>"
SelectCommand="sp_Warehouse_RowsByOrderNumberAndWarehouse"
SelectCommandType="StoredProcedure">
<SelectParameters>
<asp:QueryStringParameter Direction="Input"

Type="String" />
<asp:QueryStringParameter Direction="Input"
DefaultValue="x"
Name="@Warehouse"
QueryStringField="wh_nr"
Type="String" />
</SelectParameters>
</asp:SqlDataSource>
The address shows that the necessary parameter values are being passed to the page:
"http://address/folder/OrderPicking.aspx?afp_nr=1586474&wh_nr=02"
Any and all help much appreciated.
Regards,
Johan
My advice is free, and you may get what you paid for.

Try omitting the "@" from the name
<asp:QueryStringParameter Direction="Input"
DefaultValue="x"
Name="OrderNumber"
QueryStringField="afp_nr"
Type="String" />
<asp:QueryStringParameter Direction="Input"
DefaultValue="x"
Name="Warehouse"
QueryStringField="wh_nr"
Type="String" />

Hi,
Thanks for your reply. I omitted the @ characters, but unfortunately still no sigare.

Why this code shows two images instead of one
protected void Page_Load(object sender, EventArgs e)
{
string divs = "<div class=" + "\"vlightbox1\">";
string divend = "</div>";
string anch = divs + "<a class=" + "\"vlightbox1\" " + "href=" + "\"index_files/vlb_images1/img20200127wa0004.jpg\"" + " " + ">"
+ "<img src=" + "\"index_files/vlb_thumbnails1/img20200127wa0004.jpg\"/" + "></a>" + divend;
string fnl = anch;
var imgcontrol2 = new HtmlGenericControl(fnl);
this.Page.Form.FindControl("ContentPlaceHolder2").Controls.Add(imgcontrol2);

I tried finding the solution or lead on how to implement dynamically updating the site with progress bar but on failing I am posting here.
My problem is that, I am fetching data from 4 different sources by hitting them in realtime and every source return data in blocks of results i.e. first 10 then, then again after querying by telling I have pulled previous then it again provide more. I want to show sorted data as and when I am able to fetch (I am able to fetch successfully) i.e. if I am able to receive data from first two sites I need to show them with sort on Alphabet then if again received more from those sites or other one again I should sort till all the results are fetched.

To dynamically put the lowest rate data on top while my website is fetching the data from different sources and also to show the progresss bar.

That is a lot of different things and a lot of different code. I don’t think anyone is going to write that code for you, so where exactly are you stuck?

You may want to think of building a WebService which executes in the background and one of the methods on that WebService is to return the progress of fetching data.
Kind of a "BlueSky" answer, but building WebSites fetching lots of data which takes a long time can be quite a challenge.

When I run my code, when I want to check the user who is logged in (this is a web application), the method called is having an error saying The method or operation is not implemented.
I need help to fix it by implementing the method.
Here is where the error occurs
try
{
foreach (string caseNumber in userEnteredCaseNumberList)
{
EditCandidateCaseModel newCandidate = new EditCandidateCaseModel();
newCandidate.CaseNbr = caseNumber;
newCandidate.RequestorInfoID = Convert.ToInt32(requestorItem.Value);
newCandidate.EntryStaffUserName = Helpers.Authentication.GetADEmail();
await CandidateCaseController.PostCandidate(newCandidate);
}
}
catch (Exception ex)
{
string errorMsg = string.Format("An error has occured in {0}. \nException:\n{1}", "GetCasesButton_Click()", ex.Message);
ClientScript.RegisterStartupScript(this.GetType(), "myalert", "alert('" + errorMsg + "');", true);
}
Method that is called by line 8 with EntryStaffUserName. The error on on this method on line 7
public static string GetADEmail()
{
string retVal = string.Empty;
using (var context = new PrincipalContext(ContextType, "COURTS"))
{
UserPrincipal user = new UserPrincipal(context);
user = UserPrincipal.FindByIdentity(context, IdentityType, Environment.UserName);
retVal = user.EmailAddress;
}
return retVal;
}
|
|
|
|
|
Check the UserPrincipal.FindByIdentity functions if it has the following code in it:
throw new NotImplementedException();

FCKeditor hasn't been updated since 2007. Whilst it might work, there's a good chance there will be problems using it in newer browsers. And if you do encounter any problems, you won't get any support or bug fixes.
You'll probably have better luck using the replacement, CKeditor. You'll just need to be aware of the licensing restrictions for the free version.

That was a common error with FCKeditor, getting the text from the JavaScript object.
You will have the same issue with CKeditor as well, because it uses the same code to place and grab text from the ckeditor object. I remember having to link some Javascript to transfer the text, and check for ckinstance and ckdirty before accessing the ckobject.
From your post, I can tell your pretty new to CKeditor and haven't gotten to using js files to program the environment yet, or didn't run the sample project provided for you to learn from that is fully functional.
I suggest you run the tutorial project in ckeditor.

I did my own research, tinkering and programming, according to you in addition to FCKeditor and CKeditor, currently the programming tool supports better than CKeditor what tool do you use ?
|
|
|
|

I used both, starting with FCKEditor and then CKEditor in a Asp.Net Webform app.
I got as far as writing JS files to program the editor, JS scripts to load the HTML, get the HTML back, and wrote
Custom tools or controls to ...
Upload new images,
Set images from the Product database
Place images and text,
Load custom HtmlTemplates to showcase products
Load custom HTML sections
I got pretty good with CKEditor and customers liked it. But I haven't touched it in 3 years, I dropped Webforms and went Angular now.
I think this is what your looking for. It took me a long time to understand how to save the HTML in the editor without reloading the form, and saving when posting the entire form back to the server. It's JQuery, that can write to input elements on the webform. This file calls functions in the main ckEditor JS file. I don't remember all the details to CKEditor, but I needed a JavaScript interface to write the HTML in the content container to a textbox or input form element, since the ckEditor container is not a form element.
So you create a form element that represents the CKEditor HTML content data, and create sort of a hook to go back and forth to ckEditor object, and a panel/container to hold the CKEditor JavaScript object inside.
The function is tied to a webform button OnClientClick(update_ckEditor_Preview())
function update_ckEditor_Preview() {
var ckEditor_XHTML, ckEditor_Instance, ckEditor_Update, classic_template;
classic_template = $('[id*="_txt_ProductEditor_Template"]').val();
try {
var ckInstance = ckEditor_GetInstance();
if (ckInstance !== null) {
var ckDirty = ckInstance.checkDirty;
ckEditor_XHTML = ckInstance.getData();
ckEditor_Instance = ckInstance.getData();
if (ckDirty) {
ckInstance.resetDirty();
}
$('[id*="_panel_Display_Classic_XHTML"]').empty();
$('[id*="_panel_Display_Classic_XHTML"]').append(ckEditor_XHTML);
$('[id*="_panel_Display_Classic_XHTML"]').css('display', 'inline-block');
ckEditor_Update = true;
}
else {
ckEditor_XHTML = $('[id*="_ck_Editor_ProductXHTML"]').val();
$('[id*="_panel_Display_Classic_XHTML"]').empty();
$('[id*="_panel_Display_Classic_XHTML"]').append(ckEditor_XHTML);
$('[id*="_panel_Display_Classic_XHTML"]').css('border', 'solid 1px rgb(28,134,238)');
ckEditor_Update = true;
}
}
catch (err) {
$('[id*="_panel_ProductEditor_Basic_Image_UpdateMessage"]').css('background-color', 'rgb(176,23,31)');
$('[id*="_panel_ProductEditor_Basic_Image_UpdateMessage"]').fadeIn('normal', function () {
$('[id*="_lbl_ProductEditor_Basic_Image_UpdateMessage"]').text("Could not connect to the ckEditor interface, update has failed");
});
}
if (true === ckEditor_Update) {
$('[id*="_panel_ProductEditor_Basic_Image_UpdateMessage"]').css('background-color', 'rgb(28,134,238)');
$('[id*="_lbl_ProductEditor_Basic_Image_UpdateMessage"]').text("Preview Display Page has been updated successfully");
$('[id*="_panel_ProductEditor_Basic_Image_UpdateMessage"]').fadeIn('normal').delay(5000).fadeOut('normal');
}
else {
$('[id*="_panel_ProductEditor_Basic_Image_UpdateMessage"]').css('background-color', 'rgb(176,23,31)');
$('[id*="_lbl_ProductEditor_Basic_Image_UpdateMessage"]').text("Could not connect to the ckEditor interface, update has failed");
$('[id*="_panel_ProductEditor_Basic_Image_UpdateMessage"]').fadeIn('normal').delay(5000).fadeOut('normal');
}
return false;
}
