Body
i have this loop that checks two objects. The problem with it, is that it only checks the first one but it doesn't check the others... When my loop check the first object for picking it says if it has been picked or not, but when it loops again to check the second object it says it has not been picked, even when it was picked. So what i did is that i switched the checking process. Like now the second object gets checked than the first object gets checked. So after i did that, i got this result it says that second object got picked or not, it works fine but when it loops again it start checking the first object it says that it is not picked even when it was picked.. here is my loop <pre><code>for(int i=0; 1>=i; i++) { matWorld=entity[i]->s; // Use inverse of matrix D3DXVec3Unproject(&rayPos,&rayPos,&vp,&matProj,&matView,matWorld); D3DXVec3Unproject(&rayDir,&rayDir,&vp,&matProj,&matView,matWorld); rayDir -= rayPos; // make a direction from the 2 positions D3DXVec3Normalize(&rayDir,&rayDir); if(FAILED(D3DXIntersect(entity[i]->pDrawMesh, &rayPos, &rayDir, &hasHit, NULL, NULL, NULL, &distanceToCollision, NULL, NULL))) { PostQuitMessage(0); }; if(hasHit!=0) { entity[i]->draw=false; } } </code></pre> any idea? EDIT 2: ok i don't think you guys understood me right. I'm not trying to make my loop check more <code>entity</code>. Ok i'll this is what happening. 1. When it loops for the first time it, checks to see if <code>entity[0]</code> is picked or not, This step works fine. 2. When it loops for the second time, checks to see if <code>entity[1]</code> is picked or not, HERE IS THE PROBLEM. my loop works fine when it loops for the first time, but it doesn't work when it is looping for the second time. When i was debugging i tried this. 1. When it loops for the first time it, checks to see if <code>entity[1]</code> is picked or not, This step works fine. 2. When it loops for the second time, checks to see if <code>entity[2]</code> is picked or not, HERE IS THE PROBLEM. it seems that after the first loop there is something wrong, but i can't see what is it. By the way i don't get any errors. EDIT 3: The Entire Function <pre><code>BOOL D3dDevice::Picking(HWND hWnd, LPDIRECT3DDEVICE9 d3ddev, CXFileEntity *entity[4]) { D3DXMATRIX matProj; POINT pt; D3DVIEWPORT9 vp; D3DXMATRIX *matWorld=NULL; D3DXMATRIX matView; GetCursorPos(&pt); ScreenToClient(hWnd, &pt); d3ddev->GetTransform(D3DTS_PROJECTION, &matProj); d3ddev->GetViewport(&vp); d3ddev->GetTransform(D3DTS_VIEW, &matView); D3DXVECTOR3 rayPos((float)pt.x, (float)pt.y,0); // near-plane position D3DXVECTOR3 rayDir((float)pt.x, (float)pt.y,1); // far-plane position BOOL hasHit; float distanceToCollision; for(int i=0; i<=1; i++) { matWorld=entity[i]->s; // Use inverse of matrix D3DXVec3Unproject(&rayPos,&rayPos,&vp,&matProj,&matView,matWorld); D3DXVec3Unproject(&rayDir,&rayDir,&vp,&matProj,&matView,matWorld); rayDir -= rayPos; // make a direction from the 2 positions D3DXVec3Normalize(&rayDir,&rayDir); if(FAILED(D3DXIntersect(entity[i]->pDrawMesh, &rayPos, &rayDir, &hasHit, NULL, NULL, NULL, &distanceToCollision, NULL, NULL))) { PostQuitMessage(0); }; if(hasHit!=0) { entity[i]->draw=false; } } return hasHit; } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
