GetDlgItemText

[ragdog]

hi guys

I have a question about GetDlgItemText!
How can I check if a valid number or  a valid letter ?

greets

i have this found

this works

Code Select Expand


                invoke GetDlgItemText,hWnd,1002,addr lpBuffer,10
                mov ebx,offset lpBuffer
               
                 .if (byte ptr [ebx] >= '0' && byte ptr [ebx] <= '9' )
                     invoke MessageBox,hWnd,addr szValid,0,MB_OK
                   .else
                   invoke MessageBox,hWnd,addr szInvalid,0,MB_OK
                 .endif




Why does this not work??

Code Select Expand


                invoke GetDlgItemText,hWnd,1002,addr lpBuffer,10
                mov ebx,offset lpBuffer
               
                     .if (byte ptr [ebx] >= '0' && byte ptr [ebx] <= '9' && byte ptr [ebx] >= 'A' && byte ptr [ebx] <= 'Z')
                     invoke MessageBox,hWnd,addr szValid,0,MB_OK
                   .else
                   invoke MessageBox,hWnd,addr szInvalid,0,MB_OK
                 .endif





thanks in forward

ragdog,

Look closer...

Code Select Expand


X = '2'

if (X >= '0' and X <= '9' and X >= 'A' and X <= 'Z')
    ; do this
endif


Should be..

Code Select Expand


X = '2'

if (X >= '0' and X <= '9') or (X >= 'A' and X <= 'Z')
    ; do this
endif

If I use when I get compile this error message:

error A2154: syntax error in control-flow directive :'(

Did you took what I wrote as it is   :eek

It was pseudo code. The MASM code is...

Code Select Expand


.if (byte ptr [ebx] >= '0' && byte ptr [ebx] <= '9') || (byte ptr [ebx] >= 'A' && byte ptr [ebx] <= 'Z')
