c++ - Template class and class properties that are also templates -


I'm having trouble compiling the following headers, this is my first experience with templates and I think that something wrong Compiler point errors are being done by vector & lt; Vector & lt; T & gt; & Gt; Data _; and operator overloading function. I want to keep the data_ vector as the OptBaseMatrix object but I'm not sure how to do this ... I do not really know how to solve this problem Turned out help! 

  #ifndef OPTBASEMATRIX_H #defineOPTBASEMATRIX_H #include & lt; Vector & gt; Template & lt; Typename T & gt; Class Optbase Matrix {Public: Vector & lt; Vector & lt; T & gt; & Gt; Information_; Opt-in matrix (int rows, int colals); ~ OptBaseMatrix (); Read Zero Matrix (); Zero print matrix (); Int getRows (); Int getCols (); OptBaseMatrix & LT; T & gt; Operator + (Constant Optus Matrix & lt; T & gt; and Matrix 1, Constant Metabolism & lt; T & gt; and Matrix 2); Private: INTER Rows_; Int cols_; }; #endif // OPTBASEMATRIX_H

UPDATE : Here is a snippet from the debugger log: 

  Error 1 error C2143: Syntax error : missing ';' '& Lt;' Before Optbasematrix.h 17 TD2 error 2 error C4430: Missing type specifier - int assumed. Note: C ++ does not support the default-int optbasematrix.h 17 TD2

I have tried to modify the vector> data_; Vector> Data_by; And still get the same error: / I read somewhere that my template class header (.h) and implementation (.cpp) should be in the same file ... is it possibly related?

Update 2 : Wow! I forgot "using the namespace std"; The problem is fixed now!

Give you two & gt; / Code>. 

  vector & lt; Vector & lt; T & gt; & Gt; Information_;

Without space, & gt; & Gt; is considered as a stream extraction / right-shift operator.

In addition, you either need to declare the code as a free code or you must declare it with only one parameter: 

  // member job matrix & lt; T & gt; Operator + (Const Metrix & lt; T & gt; and others) const; // Free Function ('Friend' frees the function even if it has been declared in the scope of class definition) Buddy Matrix & lt; T & gt; Operator + (Const Metrix & lt; T & gt; & amp; LHS, Const Metrix & lt; T & gt; & amp; amp; rhs);

c++ - QtQuick: QQmlApplicationEngine failed to load component qrc:/main.qml:23 Invalid attached object assignment -

Looking at my thoughts below, am I barking the wrong tree? Or in the information given below, am I misusing the Qt API to get an error in the title? I'm trying to modify the sample to work with the default coefficic project generated from Qt Creator 3.3.0 (OpenSource). Qt 5.4.0 (GCC 4.6.1, 64bit) Based on. The first thing to look at after the code is that I stand by: The sample uses the main.cpp: qmlRegisterType & lt ; Squircle & gt; ("OpenGLUARMM", 1, 0, "Squircle"); QQuickView view; View.setResizeMode (QQuickView :: SizeRootObjectToView); View.setSource (QUrl ("QRC: ///scenegraph/openglunderqml/main.qml")); View.show (); Some name changes in my name. CPP qmlRegisterType & lt; Menuscreen & gt; ("OpenGLUnderQML", 1, 0, "Main Screen"); QQmlApplicationEngine engine; Engine.load (QUrl (QStringLiteral ("QRC: /main.qml"))); I'm not sure that the difference in using QQmlApplicationEngine...

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net - getting a value of selected radiobutton in LoadViewState -

Can I get the value of a selected radio button in the LoadViewState event of WebControl and how? All components are generated in codebehind, so I have those controls: Radiobutton list RLL; LISTIME leon; List liTwo; At this time I was stuck on that the overloaded loadviolet is not being implemented protected override zero load vivestat (object o) {action = Rbl.SelectedValue; Verb 2 = rll Selected item. value; Base.LoadViewState (O); } You also need to override the SaveViewState method. Radio button AFAIK has problems in saving their selected state.
