DirectX 9 ID3DXEFFECT for PB

[Roman]

Greetings to all!
Please help, I can understand with ID3DXEFFECT.

*Effect \SetMatrix ("mat_World_View_Proj",mat_World_View_Proj)
Here an error: “mat_World_View_Proj” the line is inadmissible, if mat_World_View_Proj that the result is not present.
Prompt how to resolve this problem.

P.S.
Excuse for my English.

Hello Roman

You need to post the tiniest code snippet possible that reproduces the problem, then someone might be able to help.

Here a code:
*effect. ID3DXEffect
D3DXCreateEffectFromFile (*D3DDevice, "ald_Parallax_Mapping.fx", 0,0,0,0, *effect, 0)

; Render_Effect
mat_World_View_Proj. D3DXMATRIX
D3DXMatrixIdentity (mat_World_View_Proj)
hr =*effect \SetMatrix (mat_World_View_Proj, mat_World_View_Proj)
At this stage an error hr.

On C ++ the first parameter a line, and the second a matrix - but PB differently.
If I shall enter a line in the first parameter SetMatrix there is a mistake{an error}.
And if to enter simply «mat_World_View_Proj» that a hr-mistake.
How to me correctly to make to install *effect \SetMatrix (mat_World_View_Proj, mat_World_View_Proj)?

hr =*effect \SetMatrix (mat_World_View_Proj, mat_World_View_Proj)
At this stage an error hr.

not enough to go on... assuming you have set up *effect correctly? and that "effect" can be used as an ID?

A bit more code needed... this isn't Texas Hold'em here!

We need code that can be executed

Thanks for answers!!!
I have understood.

In this code all OK:
mat_World_View_Proj. D3DXMATRIX
D3DXMatrixIdentity (mat_World_View_Proj)
hr = *effect\SetMatrix (*effect\GetParameterByName (0, “mat_World_View_Proj”), mat_World_View_Proj)

*effect\GetParameterByName (0, “mat_World_View_Proj”); we Receive descriptors of parameters
Now all works as it is necessary.
