Trying to load OSM on windows Form using C# and GMap.Net I am getting this error
Exception:The remote server returned an error: (403) Forbidden
private void Form1_Load(object sender, EventArgs e)
{
gMapControl1.DragButton = MouseButtons.Left;
gMapControl1.CanDragMap = true;
gMapControl1.MapProvider = GMapProviders.OpenStreetMap;
gMapControl1.Position = new GMap.NET.PointLatLng(54.6961334816182, 25.2985095977783);
gMapControl1.MinZoom = 0;
gMapControl1.MaxZoom = 24;
gMapControl1.Zoom = 9;
gMapControl1.AutoScroll = true;
}
Can you please let me know why this is happening and how I can fix it?
don't forget to set the instance mode to server/cache and set it to the instance of the open street map provider instead of 'GMapProviders.OpenStreetMap'
GMap.NET.GMaps.Instance.Mode = GMap.NET.AccessMode.ServerAndCache;
gMapControl1.MapProvider = GMap.NET.MapProviders.OpenStreetMapProvider.Instance;
It could also be your web proxy settings, see

"Hi,
All libraries that send a fake user-agent and other faked headers to make the requests appear as if they are coming from web browsers are being blocked. Fix the headers and set a real User-Agent to identify your app and the requests will work again.
Please review our usage policy:

This is verbatim reply from OSM.
https://github.com/judero01col/GMap.NET/pull/45 is being used to track this issue. And hopefully a fix will be merged in a a day or two.
I changed Map Provider from "OpenStreetMapProvider" to "GoogleMapProvider" and the error disappeared.
GMap.NET.GMaps.Instance.Mode = GMap.NET.AccessMode.ServerAndCache;
mapView.MapProvider = GMap.NET.MapProviders.GoogleMapProvider.Instance;

I have waited faithfully for well over 48 hours since generating api keys as suggested and no matter what I do, every coinbase api call gives 401 Unauthorized
I have checked basic non-authentication required calls like /time and /exchange_rates and they work fine
I am using coinbase and not coinbase pro so this is a simple api key and header based call
Have triple checked the hashing and decoding requirements, and nothing is apparent as an issue
Rather than asking to resolve coding problems from the standard examples, the ask is either
Is anyone aware of general authorization issues with the coinbase service right now ? (nothing published by coinbase)
Is there anything outside of the general code samples and documentation that needs to be done to get this damn thing authorizing ?
Any and all help appreciated.

Have added the basic code used for completeness here :
// Remove insecure protocols (SSL3, TLS 1.0, TLS 1.1)
ServicePointManager.SecurityProtocol &= ~SecurityProtocolType.Ssl3;
ServicePointManager.SecurityProtocol &= ~SecurityProtocolType.Tls;
ServicePointManager.SecurityProtocol &= ~SecurityProtocolType.Tls11;
// Add TLS 1.2
ServicePointManager.SecurityProtocol |= SecurityProtocolType.Tls12;
HttpClient client = new HttpClient();
string sTimeStamp = Convert.ToInt64(DateTime.Now.Ticks).ToString("F0", CultureInfo.InvariantCulture);
client.BaseAddress = new Uri(sUrl + sOperation);
var convertedString = Convert.FromBase64String(sAPI_EXCHANGE_SECRET);
var prehash = sTimeStamp + "GET" + sOperation + ""; // no content for now
string sSignature = HashString(prehash, convertedString);
// bunch of headers for coinbase
// Add an Accept header for JSON format.
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
client.DefaultRequestHeaders.Add("User-Agent", "CryptoAppClient"); // arbitrary user agent name
client.DefaultRequestHeaders.Add("CB-ACCESS-KEY", sAPI_EXCHANGE_KEY);
client.DefaultRequestHeaders.Add("CB-VERSION", sAPI_EXCHANGE_VERSION);
client.DefaultRequestHeaders.Add("CB-ACCESS-SIGN", sSignature);
client.DefaultRequestHeaders.Add("CB-ACCESS-TIMESTAMP", sTimeStamp);
// set up the actual call
HttpResponseMessage response = client.GetAsync("").Result;
.....
//----------------------------------------------------------------------------
private string HashString(string str, byte[] secret)
{
var bytes = System.Text.Encoding.UTF8.GetBytes(str);
using (var hmaccsha = new HMACSHA256(secret))
{
return Convert.ToBase64String(hmaccsha.ComputeHash(bytes));
}
}
Finally go it sorted, combination of timestamp value wrong and the right .net functions to encrypt the message
I am using the gdata-media-1.0-1.47.1.jar functionality to fetch media data using the com.google.gdata.client.media.MediaService.getMedia(IMediaContent mediaContent) method. For some requests I get a RedirectRequiredException. When I redo the getMedia request, using the url i get from RedirectRequiredException.getRedirectLocation(), I get an IllegalArgumentException("Trying to set foreign cookie") exception.
From what I can see, the reason for this is that the domain in the response header for the cookie doesn't match the domain of the redirect location. In com.google.gdata.client.http.GoogleGDataRequest.matchDomain() the first argument is ".docs.google.com" and the second is "docs.google.com" which makes the domain matching fail.
Is this a correct behaviour? Why is this happening? Is there something I can do about this? Am I doing anything wrong here? Is is possible to avoid this problem?
SitesService sitesService = new SitesService("SomeAppName");
try {
MediaContent mc = new MediaContent();
mc.setUri(aURI);
return sitesService.getMedia(mc);
} catch (RedirectRequiredException e) {
MediaContent mc = new MediaContent();
mc.setUri(e.getRedirectLocation());
return sitesService.getMedia(mc);
}
I have a WSDL that defines a custom SOAP-header that the client needs to send and a SOAP-Fault header that the server could send as a response.
Now I have a problem. I cannot for the life of me fathom how to set SOAP-Fault-headers on a response generated with AXIS 2 (Version 1.6.1) or read SOAP-Headers that come with a request.
Can anyone point me in the right direction?
Thank you very much in advance.
If is security related you should look to Rampart.
If not, try looking into
ClientSide:
From your stub, retrieve the ServiceClient via _getServiceClient().
enter link description here
ServerSide:
If I recall correctly is done via MessageContext, so from axiscontext opbtain current message context.
Add custom fault to soap response. This can be done in one of two ways.
1) Simply throwing a Java exception with a message will generate a simple Axis2 fault
Example:
throw new java.lang.UnsupportedOperationException("Please implement " +
this.getClass().getName() + "#SomeOperationName");
Also please note: If you generated your service using the Axis2 WSDL2JAVA utility, the line above will be added to the MyServiceName_Skeleton source for each defined WSDL Operation.
Once the .aar is deployed, connectivity to each operation can be verified using a web browser, e.g. https://server:port/axis2/services/MyServiceName?SomeOperationName.
2) Ensure that the WSDL defines an optional (occurs:0) custom Fault structure. This can be sent to client with any other required (and empty) elements.
Example:
com.some.service.operation.SomeOperationNameResponse_Type OPRT = new com.some.service.operation.SomeOperationNameResponse_Type();
com.some.service.SomeOperationNameResponse OPR = new com.some.service.SomeOperationNameResponse();
.
.
.
if ((rcStatusString.equals("Succeeded")) || (rcStatusString.equals("Warning"))) {
<build happy path response>
} else if (rcStatusString.equals("Failed")) {
final MYFault fault = new MYFault();
final MYFault_Type faultType = new MYFault_Type();
final MYFaultList faultList = new MYFaultList();
final MYFaultList_Type faultListType = new MYFaultList_Type();
faultType.setFaultCode("10100");
faultType.setFaultSubcode("9999");
faultType.setFaultType(FaultType_Enum.SYSTEM);
faultType.setFaultReasonText("Some Operation Failed");
faultType.setSeverity(FaultSeverity_Enum.CRITICAL_ERROR);
//fault.setMYFault(faultType);
faultListType.addMYFault(faultType);
OTHRTYPE.setAValue("");
OPRT.setAValueType(OTHRTYPE);
OPRT.setMYFaultList(faultListType);
} else {
throw new java.lang.UnsupportedOperationException(
"MYSERVICE: [Some Operation] Session: "+sessVal+" Request ID: "+rcRequestId+" Unrecognized Completion Status ["+rcStatusString+"]");
}
OPR.setSomeOperationResponse(OPRT);
return OPR;
}
I am trying to download HTML content from any URL through webbrowser control in C#.net.
I choose webrowser to handle Javascript issues. I am using webbrowser control without placing
it on the form. It works great for one url, but when I call it for multiple urls I am unable
to download the page.
Here is the code
GetWebpage()
{
System.Windows.Forms.WebBrowser wb = new System.Windows.Forms.WebBrowser();
wb.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(wb_DocumentCompleted);
wb.Navigate(sURI, false);
bDocumentLoaded = false;
while (!bDocumentLoaded)
{
Application.DoEvents();
Thread.Sleep(100);
}
sHTML = wb.DocumentText;
bDocumentLoaded = false;
}
Event:
private void wb_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
System.Windows.Forms.WebBrowser webBrowser1;
webBrowser1 = sender as WebBrowser;
string strTit = webBrowser1.DocumentTitle;
string str = webBrowser1.DocumentText;
bDocumentLoaded = true;
}
Cheers,

You can use webclient object to fetch data from some url.
Try using Downloading String
public static void DownloadString (string address)
{
WebClient client = new WebClient ();
string reply = client.DownloadString (address);
Console.WriteLine (reply);
}
You can also use ASYC method of same downloading string.
I think your problem is that some sites are detecting specific browsertype and then they are returning HTML
Try setting the HeaderProperty of WebClient Object this is a list of HttpWebRequest Object
For Example
myWebClient.Headers.Add("Content-Type","application/x-www-form-urlencoded");
Modify the useragent of HTTPWEBRequest then add to headers.
HTTPWEBRequest.UserAgent=".NET Framework Test Client";
You can check more information about this in MSDN Link
I might recommend using the mshtml and SHDocVW libraries and using approach found in the answer here:
Unable to to locate and click a submit button using mshtml.HTMLInputElement
I have this code which is working, to load a Google Spreadsheet and load some data from it. If the spreadsheet in question is public, how do i modify the code to not require a username/password?
$key="keytothespreadsheet";
$user="test#example.com";
$pass="*****";
$authService = Zend_Gdata_Spreadsheets::AUTH_SERVICE_NAME;
$httpClient = Zend_Gdata_ClientLogin::getHttpClient($user, $pass, $authService);
$gdClient = new Zend_Gdata_Spreadsheets($httpClient);
$query = new Zend_Gdata_Spreadsheets_DocumentQuery();
$query->setSpreadsheetKey($key);
$feed = $gdClient->getWorksheetFeed($query);
print_r($feed);
In the following line, the HTTP client is optional:
$gdClient = new Zend_Gdata_Spreadsheets($httpClient);
So, just don't pass it. The following are equivalent:
$gdClient = new Zend_Gdata_Spreadsheets();
// or
$gdClient = new Zend_Gdata_Spreadsheets(null);
// or
$gdClient = new Zend_Gdata_Spreadsheets(new Zend_Http_Client());
Like #Matt, I wanted to access a public spreadsheet without supplying credentials. Thanks to #Derek Illchuk, I got part of the way there. It still wasn't working, however, until I learned the following:
Note that the File > Publish to the Web feature is not the same thing as Sharing Settings > Public On The Web. If you forget to enable "Publish to the Web", you'll get this error: "Expected response code 200, got 400 The spreadsheet at this URL could not be found. Make sure that you have the right URL and that the owner of the spreadsheet hasn't deleted it."
In the "Publish to the Web" settings, be sure to uncheck "Require viewers to sign in with their ___ account.". Otherwise you'll get this error: "Expected response code 200, got 403 You do not have view access to the spreadsheet. Make sure you are properly authenticated."
According to Google's documentation, "The spreadsheets feed only supports the 'private' visibility and the 'full' projection." However, I found that I needed to specify 'public' visibility and 'basic' projection. Otherwise I got this error:
"Expected response code 200, got 501 Bad or unsupported projection for this type of operation."
Here is what worked for me:
$spreadsheetService = new Zend_Gdata_Spreadsheets(null);
$query = new Zend_Gdata_Spreadsheets_CellQuery();
$query->setSpreadsheetKey($spreadsheetKey);
$query->setWorksheetId($worksheetId);
$query->setVisibility('public'); //options are 'private' or 'public'
$query->setProjection('basic'); //options are 'full' or 'basic'
$cellFeed = $spreadsheetService->getCellFeed($query);
foreach ($cellFeed as $cellEntry) {
$text = $cellEntry->content->text;
//Do something
break; //I only wanted the first cell (R1C1).
}
