Send array to shader program

Hi
I confuse when send array data to shader program e.g.

Cpu pass ->

float mBloomTexWeights[15][4];
services->setPixelShaderConstant("sampleWeights", mBloomTexWeights[0], 60);

Shader pass i used ->

uniform float4 sampleWeights[15];

That's correct or not

Best regards,

Hmm, should work. Not sure, if it's safe, though. Maybe BlindSide or Nadro can give a hint.

Are you using an AMD video card? I found some can't receive arrays in GLSL properly, not sure if that was fixed or not.
