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.

hi all
stuckt agein
hope i not highjack this hole topic
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 />
}<br />
void Disp::Lock_Up(System::Object ^o, System::Windows::Forms::MouseEventArgs ^e){<br />
>>>>>>>>>>>>>> not like this but how ??? :confused: <br />
Lock->MouseMove->Remove(this, &Disp::Lock_Drag);<br />
<<<<<<<<<<<<<<<br />
}

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.

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
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();
dgv->Rows[0]->Cells[0]->Value = "new date";
dgv->Rows[0]->Cells[1]->Value = "new number";
dgv[0, 0]->Value = "new date";
dgv[0, 1]->Value = "new number";
Don't be overcome by evil, but overcome evil with good

hi all

textBoxeS[0]->BackColor = SystemColors::Window;<br />
<br />
<br />
MeM::MeM(void)<br />
{ <br />
GlobalMemoryStatus (&stat);<br />
}<br />
System::String^ MeM::X(){ <br />
<br />
how do i cast / convert this ---->>>><br />
<br />

return gcnew String(a);
<br />
<<<<---------- PROBLEM HERE<br />

You can't just cast a numeric to a character and then use it in string library functions because they need a null terminator. There are several C/C++/STL implementations like ltoa() and sprintf() etc. that you should research

cool !
thx a lot !
working so fare
System::String^ MeM::X(){
char a[200];
sprintf_s( a,200, "%d", stat.dwTotalPhys );
return gcnew System::String(a);
}

Check out Object.ToString(). It is overridden for pretty much all base types.
System::String^ MeM::X()
{
return stat.dwTotalPhys.ToString();
}

Heh now what did I do?
The OP wanted a string representation of a DWORD right?
