Use WM_KEYDOWN as a toggle instead of an event that actually moves your character. You've probably discovered by now that your character movement corresponds to how repeat keys work. Therefore;

MoveFlag ^= 1;

Then in a timer event check if the flag is on and if so move your character.

if (MoveFlag && 1)
   .... Move Character

If you want to move in all four directions or even diagonally then just use a bit position in MoveFlag array to represent up down left right. If you use a 4 bit or 8 bit values in MoveFlag you can even change the speed you want your character to move in that direction relative to the rest.

So lets say MoveFlag represents Left Up Right Down each having a 4 bit value. Then MoveFlag = 0460H. This would move your character 4 pixels up and 6 right everytime your timer event was executed. Of course there is a lot of code that needs to be implemented to make this work, but I think you understand now how using WM_KEYDOWN, WM_KEYUP as toggles and then a timer works much better for your objective.

NOTE: I code exclusively in assembly so my C++ syntax may not be correct, but procedurally this is how I would implement.
