c++ Class Header - "error: expected unqualified-id before ')' token" -


I should look a bit simpler, but in such a short time I have to do so that I have to do more work. Anyway, here's the place where I'm getting the error. 

  #include & lt; Iostream & gt; # Include & lt; Algorithm & gt; #ifndef number # defined number class number {public: number () {efficiency = 5; Used = 0; Data = New unsigned long [capability];}

This is simply a creator for class numbers as follows: The private sector of the class is as follows.

Private: unsigned long * data; Used Std :: size_t; Std :: size_t Capacity; };

Again, maybe it's something that I can not see right now and I'm sure others have to run into problems too.

Edit: The error is as follows 

  numbers.h: 9: 11: error: before expected inefficient id) 'token number () {capability = 5; Used = 0; Data = New unsigned long [capability];} ^

Run through a preprocessor, It: 

  #ifndef number # defined number class number {public: number () {capability = 5; Used = 0; Data = new unsigned long [capability];}

becomes it : 

  class {public: () { Capacity = 5; Used = 0; Data = New unsigned long [capability];}

Your class name is similar to your included-guard fence post macro, as it will be replaced by number . < Em> anything .. you will not get a class name, nor the constructor's name. Do not do it

Try: 

  #ifndef MYAPP_NUMBERS_H #define MYAPP_NUMBERS_H #include & lt; Iostream & gt; # Include & lt; Algorithm & gt; Class number {public: number () {efficiency = 5; Used = 0; Data = new unsigned long [capacity]; } ... etc ...

sqlite3 - UPDATE a table from the SELECT of another one -

I have the first table article where some data is missing. In the table, articles_tmp I have a part of the missing data. So I want to update the articles. Where the path path is data in articles_tmp.path where the path is not zero . With SQLite , it does not work: update article SET path = (SELECT at.path FROM Articles_tmp as AS, WHERE at.article_id = a.id and a.asp, the text is in the form and not on. It has been transmitted) where the path is null MS Access Along with, it works fine: Update Articles Join the Inner Articles at articles_tmp articles.id = articles_tmp.id SETP articles.path = articles_tmp.path Can anyone help? Sin CE SQL Server Syntax, which I provided, was not working, here this solution With whom I have come. A little modification of your original query, but with my "correlation" suggestion added. There is a SQL Bella for this: Here is the code: update article SET path = (SELECT path from articles_tmp AS T WHERE t.id

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ

The code works in my place, although the new HTML / CSS does not render after every iteration of the loop and when all this is done, then display only the text of 100 px size.
