Disable accelerator table items in MFC

Question

I need to temporarily disable several items from the accelerator table when the input focus is in the CEdit field.

My application has several commands related to keyboard keys (A, S, D, etc.), and I need to disable them while the user enters text in the field.

Answer 1

You can try CopyAcceleratorTable to get ARRAY from ACCEL structures, then edit the ones you don't want Call DEstroyAcceleratorTable in the current table. Then use CreateAcceleratorTable to create a new table with the edited accelerator table.

Answer 2

The answer from Goz works very well. To save all other people for a while, here is an example code that follows his suggestion:

// Allocate the accelerator buffer HACCEL hAccelOld = LoadAccelerators(AfxGetInstanceHandle(),MAKEINTRESOURCE(IDR_ACC_TECONTROL)); int iNumAccelerators = CopyAcceleratorTable(hAccelOld, NULL, 0); ACCEL *pAccels = new ACCEL[iNumAccelerators]; // Copy the current table to the buffer VERIFY(CopyAcceleratorTable(hAccelOld, pAccels, iNumAccelerators) == iNumAccelerators); // Modify the pAccels array as required ... // Destroy the current table resource... VERIFY(DestroyAcceleratorTable(hAccelOld) == TRUE); // ... create a new one, based on our modified table m_hTerAcceleratorTable = CreateAcceleratorTable(pAccels, iNumAccelerators); ASSERT(m_hTerAcceleratorTable != NULL); // Cleanup delete[] pAccels;
