how I can make this Output?
Text(format: LocalizedStringKey("ImpressEmail %#"), ": app.example#emample.org")
The result should be :
Email: app.example#example.org
In my localizationfile I have the following string::
"ImpressEmail" = "Email";
you have to use this in .string file
"ImpressEmail %#" = "Email: %#";
and call it like this
Text("ImpressEmail \("email")")

I have a string which consist of data along with spaces i want to sort this string into particular variables
eg.
" Company Name : ABC Department : TESTING";
i want to split this string and get the company name and department name to add to their particular variable
You will have a pain in the neck for achieving that taks because the data is ill formatted,
your goal is to obtain from the string something like:
Company Name = ABC
Department = TESTING
even using the method split, you need a token that you dont have...
the suggestion i can provide is to redefine those strings in something well formatted and parsable... json is a good candidate for this task
imagine this example using json objects:
QString str3 = "{\"Company Name\" : \"ABC\", \"Department\" : \"TESTING\", \"Number\" : 123, \"Updated\" : false}";
then you need to "parse" the string into a json object, then get those "values" for the "keys"
like:
QJsonDocument doc1 = QJsonDocument::fromJson(str3.toUtf8());
QJsonValue company = doc1["Company Name"];
QJsonValue dept = doc1["Department"];
QJsonValue number = doc1["Number"];
QJsonValue updated = doc1["Updated"];
qDebug()<< "Company: " << company.toString();
qDebug()<< "Department: " << dept.toString();
qDebug()<< "Number: " << number.toInt();
qDebug()<< "Updated: " << updated.toBool();
your output will look like:
Company: "ABC"
Department: "TESTING"
Number: 123
Updated: false
The backend of my application makes a request to:
https://graph.facebook.com/v2.8/me?access_token=<firebase-access-token>&fields=id,name,first_name,birthday,email,picture.type(large){url}&format=json&method=get&pretty=0&suppress_http_code=1
I get a successful (200) response with the JSON data I expect and picture field as such:
"picture": {
"data": {
"url": "https://platform-lookaside.fbsbx.com/platform/profilepic/?asid=<asid>&height=200&width=200&ext=<ext>&hash=<hash>"
}
}
(where in place of <asid> and <ext>, there are numbers and <hash> is some alphanumeric string).
However, when I make a GET request to the platform-lookaside URL above, I get a 404 error.
It's been happening every time since my very first graph.facebook request for the same user. The very first one returned a platform-lookaside URL which pointed to a proper image (not sure if this is simply coincidence).
Is there something I'm doing wrong or is this likely a bug with the Facebook API?
FB currently seems to have issues with some CDNs and therefore your issue might be only temporary. You should also see missing/broken images on some places on fb dot com. Worst time to debug your issue :)
Try this code it worked for me
GraphRequest request = GraphRequest.newMeRequest(
AccessToken.getCurrentAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
#Override
public void onCompleted(JSONObject object, GraphResponse response) {
// Insert your code here
try {
String name = object.getString("name");
String email = object.getString("email");
String last_name = object.getString("last_name");
String first_name = object.getString("first_name");
String middle_name = object.getString("middle_name");
String link = object.getString("link");
String picture = object.getJSONObject("picture").getJSONObject("data").getString("url");
Log.e("Email = ", " " + email);
Log.e("facebookLink = ", " " + link);
Log.e("name = ", " " + name);
Log.e("last_name = ", " " + last_name);
Log.e("first_name = ", " " + first_name);
Log.e("middle_name = ", " " + middle_name);
Log.e("pictureLink = ", " " + picture);
} catch (JSONException e) {
e.printStackTrace();
Log.e("Sttaaaaaaaaaaaaaaaaa", e.getMessage());
}
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,email,link,last_name,first_name,middle_name,picture");
request.setParameters(parameters);
request.executeAsync();
I am developing a quick DICOM viewer using DCMTK library and I am following the example provided in this link.
The buffer from the API always returns null for any tag ID, eg: DCM_PatientName.
But the findAndGetOFString() API works fine but returns only the first character of the tag in ASCII, is this how this API should work?
Can someone let me know why the buffer is empty the former API?
Also the DicomImage API also the same issue.
Snippet 1:
DcmFileFormat fileformat;
OFCondition status = fileformat.loadFile(test_data_file_path.toStdString().c_str());
if (status.good())
{
OFString patientName;
char* name;
if (fileformat.getDataset()->findAndGetOFString(DCM_PatientName, patientName).good())
{
name = new char[patientName.length()];
strcpy(name, patientName.c_str());
}
else
{
qDebug() << "Error: cannot access Patient's Name!";
}
}
else
{
qDebug() << "Error: cannot read DICOM file (" << status.text() << ")";
}
In the above snippet name has the ASCII value "50" and the actual name is "PATIENT".
Snippet 2:
DcmFileFormat file_format;
OFCondition status = file_format.loadFile(test_data_file_path.toStdString().c_str());
std::shared_ptr<DcmDataset> dataset(file_format.getDataset());
qDebug() << "\nInformation extracted from DICOM file: \n";
const char* buffer = nullptr;
DcmTagKey key = DCM_PatientName;
dataset->findAndGetString(key,buffer);
std::string tag_value = buffer;
qDebug() << "Patient name: " << tag_value.c_str();
In the above snippet, the buffer is null. It doesn't read the name.
NOTE:
This is only a sample. I am just playing around the APIs for learning
purpose.
The following sample method reads the patient name from a DcmDataset object:
std::string getPatientName(DcmDataset& dataset)
{
// Get the tag's value in ofstring
OFString ofstring;
OFCondition condition = dataset.findAndGetOFString(DCM_PatientName, ofstring);
if(condition.good())
{
// Tag found. Put it in a std::string and return it
return std::string(ofstring.c_str());
}
// Tag not found
return ""; // or throw if you need the tag
}
I have tried your code with your datasets. I just replaced the output to QT console classes to std::cout. It works for me - i.e. it prints the correct patient name (e.g. "PATIENT2" for scan2.dcm). Everything seems correct, except for the fact that you apparently want to transfer the ownership for the dataset to a smart pointer.
To obtain the ownership for the DcmDataset from the DcmFileFormat, you must call getAndRemoveDataset() instead of getDataset(). However, I do not think that your issue is related that. You may want to try my modified snippet:
DcmFileFormat file_format;
OFCondition status = file_format.loadFile("d:\\temp\\StackOverflow\\scan2.dcm");
std::shared_ptr<DcmDataset> dataset(file_format.getAndRemoveDataset());
std::cout << "\nInformation extracted from DICOM file: \n";
const char* buffer = nullptr;
DcmTagKey key = DCM_PatientName;
dataset->findAndGetString(key, buffer);
std::string tag_value = buffer;
std::cout << "Patient name: " << tag_value.c_str();
It probably helps you to know that your code and the dcmtk methods you use are correct, but that does not solve your problem. Another thing I would recommend is to verify the result returned by file_format.loadFile(). Maybe there is a surprise in there.
Not sure if I can help you more, but my next step would be to verify your build environment, e.g. the options that you use for building dcmtk. Are you using CMake to build dcmtk?
I have this C++ code, and am having trouble json serializing it.
string uInput;
string const& retInput;
while(!std::cin.eof()) {
getline(cin, uInput);
JSONExample source; //JSON enabled class from jsonserialize.h
source.text = uInput;
//create JSON from producer
std::string json = JSON::producer<JSONExample>::convert(source); //string -> returns {"JSONExample":{"text":"hi"}}
//then create new instance from a consumer...
JSONExample sink = JSON::consumer<JSONExample>::convert(json);
//retInput = serialize(sink);
// Json::FastWriter fastWriter;
// retInput = fastWriter.write(uInput);
retInput = static_cast<string const&>(uInput);
pubnub::futres fr_2 = pb_2.publish(chan, retInput);
cout << "user input as json which should be published is " << retInput<< std::endl;
while(!cin.eof()) {
getline(cin, uInput);
newInput = "\"\\\"";
newInput += uInput;
newInput += "\\\"\"";
Instead of typing in the message like "\"hi\"", this code takes "hi" and does it.
If the change you described made the "Invalid JSON" disappear, then a "more correct" solution would be, AFAICT, to change the publish() line to:
pubnub::futres fr_2 = pb_2.publish(chan, json);
Because json already has JSON serialized data. Of course, if that JSON is what you want to publish.
Is it possible to obtain the string equivalent of protobuf enums in C++?
e.g.:
The following is the message description:
package MyPackage;
message MyMessage
{
enum RequestType
{
Login = 0;
Logout = 1;
}
optional RequestType requestType = 1;
}
In my code I wish to do something like this:
MyMessage::RequestType requestType = MyMessage::RequestType::Login;
// requestTypeString will be "Login"
std::string requestTypeString = ProtobufEnumToString(requestType);
The EnumDescriptor and EnumValueDescriptor classes can be used for this kind of manipulation, and the
the generated .pb.h and .pb.cc names are easy enough to read, so you can look through them to get details on the functions they offer.
In this particular case, the following should work (untested):
std::string requestTypeString = MyMessage_RequestType_Name(requestType);
See the answer of Josh Kelley, use the EnumDescriptor and EnumValueDescriptor.
The EnumDescriptor documentation says:
To get a EnumDescriptor
To get the EnumDescriptor for a generated enum type, call
TypeName_descriptor(). Use DescriptorPool to construct your own
descriptors.
To get the string value, use FindValueByNumber(int number)
const EnumValueDescriptor * EnumDescriptor::FindValueByNumber(int number) const
Looks up a value by number.
Returns NULL if no such value exists. If multiple values have this >number,the first one defined is returned.
Example, get the protobuf enum:
enum UserStatus {
AWAY = 0;
ONLINE = 1;
OFFLINE = 2;
}
The code to read the string name from a value and the value from a string name:
const google::protobuf::EnumDescriptor *descriptor = UserStatus_descriptor();
std::string name = descriptor->FindValueByNumber(UserStatus::ONLINE)->name();
int number = descriptor->FindValueByName("ONLINE")->number();
std::cout << "Enum name: " << name << std::endl;
std::cout << "Enum number: " << number << std::endl;
