Hi, currently I'm building a block that take dynamic inputs then output a Matrix with dynamic size with respect to the number of inputs.
So, I suppose the inputs are Audio-Buffers , and the output is a Matrix.

I still can't figure out:

1. How to set different number of inputs, and then I can access them through a loop ?

2. How to change the size of the output matrix (as I found in the reference manual, the IMatrix class doesn't have ReSize() function).

can you help me? I would be very grateful. Thanks,

Quan

well, I manage to solve the 2nd problem, by using double_matrix_init_info_ptr.

But still stuck at the 1st one...

To iterate the inputs:
int num = GetSignature()->GetInputs()->GetNumItems();
for( int i = 0; i < num; ++i )
{
IInputPinSignature* inputPtr = GetSignature()->GetInputs()->GetItem( i );
// ....
}


You cannot explicitly set the numer of inputs; however, you can simpli use SetInput to add new inputs to your block (using different identifiers), or RemoveInput to delete them

hi,

I can show the addition inputs now.. But when I change the number of inputs parameter, the block is not updated, only if I reset eyesweb it'll update.

so, In which method (i.e ::InitSignature() , ::CheckSignature()...) I should add SetInput/RemoveInput to register/remove a new one?

Thanks,

Quan

hi,

I attach the code for a simple block that has multiple inputs (type double) then output a matrix. I managed to change the inputs (tested in debug mode the value of GetSignature()->GetInputs()->GetNumItems()).

The block works fine with constant Number of Inputs, but when I change the number of inputs, the block itself doesn't update, in GUI it shows the old inputs. If, for example, I reduce the inputs, then point the mouse cursor to the pins that have been supposed to be removed , an error occurred and the eyesweb crashed !
If I restart eyesweb after changing the number of inputs, the block now is updated with the right number of input pins.

I try to modify the code by putting the SetInput/RemoveInput in some ways but .. seem like I still go on the wrong ways.

After changing the numer of inputs, outputs, or parameter, you have to call the method
Notify_SignatureChanged()
to see your changes reflected in the GUI.

hi, now all the bug have gone ..


THANK YOU VERY MUCH !!!

Seems like one library was compiled with "multithreaded" static linking to C runtime and another was with "multithreaded DLL" dynamic linking to C runtime via msvcr90.dll/msvcp90.dll. All of them have to match.
