hi all

if some one whit knowledege coud sacrify 2-3 minutes it woud save me a day time Wink | ;)

a have a class X now i wana make a class Y wich woud derive all methodes, variables of X and has new ones
i wana ensure in X that certain methode are implemented in Y wich arent in X but declared
i wana overwrite methodes of X in Y
how do i write functions for operators that this works :

Myclass a=Myclass();
a++;
a=a*a;
...
..

i was try to use System::String inside a struct and was geting erros that i cant use a managed type in a struct blabla
i have solved this by using a class instead but woud by nice to know if there is a way around
similair problems seams to ocure if i try to use them as static
i woud like to have a static array in my class whit a pointer to all instances of this class this is important else way i have trubel

if some one coud give me a 10-20 line example it woud by great
just code no need for description

This is the C++/CLI forum, I assume this question is about C++ in general. I recommend buying a very base level beginner book and working through it.

void Disp::Lock_Down(System::Object ^o, System::Windows::Forms::MouseEventArgs ^e){<br />
	Lock->MouseMove += gcnew System::Windows::Forms::MouseEventHandler( this, &Disp::Lock_Drag );<br />
	MousePosition=MainF->MousePosition;<br />

	Lock->MouseMove->Remove(this, &Disp::Lock_Drag);<br />
<<<<<<<<<<<<<<<br />
}

-- modified at 9:48 Friday 25th May, 2007

this works

void Disp::Lock_Down(System::Object ^o, System::Windows::Forms::MouseEventArgs ^e){<br />
	t = gcnew System::Windows::Forms::MouseEventHandler( this, &Disp::Lock_Drag );<br />
	Lock->MouseMove += t;<br />
	MousePosition=MainF->MousePosition;<br />
}<br />
void Disp::Lock_Up(System::Object ^o, System::Windows::Forms::MouseEventArgs ^e){<br />
	Lock->MouseMove -= t;<br />
}

BUT i realy not like "t"
is there a way to get it somehow else mayby out of Object ^o or MouseEventArgs ^e
or how ever whit out the need to store it by my self

1 - this is the C++/CLI forum. It's different to C++
2 - this is a place to ask for help with your code, not to request people give you code. I know of no place that allows you to ask for people to just write code for you, without offering to pay them for it.

First step, think about what you're doing. Like posting a question and putting 'question' in the header. Or asking a C++ question in the C++/CLI forum.

datagridview data

Xeef24-May-07 11:19

24-May-07 11:19

hi agein to all

array<String^>^row0 = {"11/22/1968","29"};<br />
      DataGridView1->Rows->Add( row0 );<br />
      row0[0]="2";<br />
      Object^ a= DataGridView1->DataSource;<br />
      a[0]="123";

error C3915: 'System::Object' has no default indexed property (class indexer)

how do i acces the rows after they are created / aplyed i havent try it but i am prety sure i coud overwrite it
like DataGridView1->Rows->Add( somethingelse ); mayby not whit add :p
it woud just append / push it in this case
any way the question is how can i acces it streigt to replace data something like

DataSource[row][col]= "my new value";

i not wana use databinding to a data base as the data are live generated and i dont think it woud make thinks easyer any way Wink | ;)

on top if this is there any way to list the content and types whats in an object
some recursive loop wich woud rotate truh all elements of the object by it an array a mullti dim array or what ever object combination

If i'm following you right i think you wanna do something like this

DataGridView^ dgv = gcnew DataGridView();

//---Add rows to the DataGridView


//this
dgv->Rows[0]->Cells[0]->Value = "new date";
dgv->Rows[0]->Cells[1]->Value = "new number";

//or this
dgv[0, 0]->Value = "new date";
dgv[0, 1]->Value = "new number";

Don't be overcome by evil, but overcome evil with good
