c# - How do you get a value from a TextField in DataGridView while the field is being updated -

-

i have datagridview text in there (i.e. datagridviewtextboxcolumn), , every time text changes in 1 of these fields, update method has called somewhere else. however, noticed when updating textbox, value in cell not updated yet.

class myform : form {     private system.windows.forms.datagridview m_datagridview;     private system.windows.forms.datagridviewtextboxcolumn m_textboxcolumn;      private void m_datagridview_editingcontrolshowing(object sender, datagridvieweditingcontrolshowingeventargs editevent)     {         if (editevent.control textbox != null)         {             textbox textbox = editevent.control textbox;             textbox.textchanged -= new eventhandler(textbox_textchanged);             textbox.textchanged += new eventhandler(textbox_textchanged);         }     }      private void textbox_textchanged(object sender, eventargs e)     {         updatetext();     }      private void updatetext()     {         foreach (datagridviewrow row in m_datagridview.rows)         {             if (row.cells[1].value != null)             {                 string text = row.cells[1].value.tostring();                 system.diagnostics.debug.writeline(text);             }         }     } }

so give example: if text in textbox "f", , type "oo", expect console output:

"f" "fo" "foo"

instead, writes is:

"f" "f" "f"

is there way access contents of textboxes within in updatetext() method while textboxes being edited?

the datagridviewcell.value won't updated right while type in editing control. it's design. value updated after it's validated when currentcell not in edit mode. think want this:

private void textbox_textchanged(object sender, eventargs e) {     updatetext(sender control); } private void updatetext(control editingcontrol) {   system.diagnostics.debug.writeline(editingcontrol.text); }

update

i think can try thing this:

string editingtext; int editingrowindex = -1; private void textbox_textchanged(object sender, eventargs e) {     editingrowindex = ((datagridviewtextboxeditingcontrol)sender).editingcontrolrowindex;     editingtext = (sender control).text;     updatetext(); } private void updatetext() {     foreach (datagridviewrow row in m_datagridview.rows)     {         if (row.cells[1].value != null)         {             string text = row.index == editingrowindex ?                           editingtext : row.cells[1].value.tostring();             system.diagnostics.debug.writeline(text);         }     } }

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
