apache - Error executing a program using system() from PHP: terminate called after throwing an instance of 'std::logic_error' -


Here is a piece of code in my index.php 

   Php / * CMD One program is subtle by other people, which I do not know much / $ CMD = "FullPath / CMD"; $ Retirement = 0; System ($ cmd, retired); ? & Gt; & Lt; P id = "return" & gt; & Lt ;? Php echo $ rate? & Gt; & Lt; / P & gt;

If I run the program in a command line like this: $ absolutepat / cmd and then resonance $? I get 0, which is correct

If I run index.php in the command line like this: php -f index.php me And

In the output, which is correct.

However, if I open the web page (both Chrome and IE) in the browser, then give me the & lt; P id = 'return' & gt; 134 & lt; / P & gt; and error message:

The end of 'std :: logic_error' is said after throwing an example - what (): the original string: _ S_construct null valid is not valid

The problem looks like this one which I've found stackoverflow: While exception is thrown is different.

If return_var argument exists, return status: div class = "post-text" Itemprop = "text">

The executed command will be written to this va, therefore, the return status is 134. Since 128, the situation outside, i.e., 128 + n where n is a small positive number usually means that the programmable crashed with 'N'. . Therefore, this is indicative 6. According to, signal 6 means 'cancellation signal'.

So, I guess, external programs can not be run by the $ cmd browser.

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
