  I’m using c++ and have an application built over 15 years ago with this spread 8 grid.We have a new requirement to enable multiblock selects. The default of the grid is to not allow this.

  I do the following:
  
  SSSetBool(m_hWnd, SSB_RETAINSELBLOCK, TRUE);
  
  SSSetBool(m_hWnd, SSB_ALLOWMULTIBLOCKS , TRUE );

  When I select a single block, both SSGetMultiSelBlocks and SSGetSelectBlock will return the block.
  
  When I hold down the Ctrl button and mouse select a second block, as soon as I press the left mouse button to select the second block, the first block is no longer highlighted.
  
  I can not select a second block.
  
  I thought that maybe we are intercepting the Ctrl key in a PreTranslateMessage and not passing it to the grid. This is not the case as we pass it to the grid. I proved this by trying Ctrl-space, which selects the current column.

  Any help in getting this working would be appreciated.

  I’ve discovered my problem. We were calling SSSetActiveCell on the Leave cell message, after a left mouse click, which resets the blocks selected.

  Although I can now see multiple blocks selected in the grid, I only get one block returned in SSGetMultiSelBlocks. Using Spread 8.0.22

  Correction, I get all blocks except the last block highlighted.

  Add debugging statements to track the selection state. For example, log the current selection before and after a mouse click to see if the selection is indeed being cleared. This can help pinpoint where the logic is going awry.

  I got this working by calling SSGetMultiSelBlocks and storing the blocks. This has all but the last selected. Then I call SSGetSelectBlock and add that. Now I have all selected blocks.

  Special themed levels Block Blast introduce unique obstacles, such as locked blocks or rotating grids, requiring players to think outside the box.

  It sounds like a frustrating issue! Have you checked if any other settings or software conflicts might be overriding SSB_ALLOWMULTIBLOCKS? Also, ensuring you’re using the correct version and checking for any required updates could help. Hope you get it resolved soon! geometrylite.cc game
