How can I Handle character 'a' and character 'A' in pretranslate Message

Naveen

I think if u handle WM_CHAR instead of WM_KEYDOWN, you can identify 'a' and 'A'.

You may use GetKeyState(VK_SHIFT) [^] to distinguish between lower case and upper case keys in PreTranslateMessage. :)

Make a try before arguing ;P (i.e. CAPS LOCK key down makes GetKeyState(VK_SHIFT) returning the same value it returns whenever SHIFT key is held down) :)

But I tried now. GetKeyState(VK_SHIFT) is not giving the same value when shift key is down and when CAPS LOCK key is on. Did you actually check like this..? if( GetKeyState(VK_SHIFT)&0x8000 )

Well, actually it is not the same value, but bit 0 contains the meaningful info in both cases, hence GetKeyState(VK_SHIFT) & 0x0001 should do the trick. :)

I dont think so. Cause the low bit indicates the key is toggled. Suppose the application is started and at that state if( GetKeyState(VK_SHIFT) & 0x0001) - > will return false. Then I press shift key and release it. After that if( GetKeyState(VK_SHIFT) & 0x0001) - > will return true. Then if i again press shift and release, if( GetKeyState(VK_SHIFT) & 0x0001) - > will return false. So basically, checking the 0 bit have no meaning in the case of shift key. 0th have use only in the case of toggle keys such as CAPS LOCK, NUM LOCK etc...

Again, make a test. (I did). :)
