mov hWnd,eax
szClassName, szDisplayName,Wtx, Wty, Wwd, Wht have all been set
complied but no window was created~~~
When debugging, I find that after CreateWindowEx, hWnd(eax) = 000000...
need help~~~
Is hInst initialised? I noticed hInstance is but no hInst
What does RegisterClassEx return?
If you are using windbg try !gle
sorry because I cut code from two proc together...
hInst = hInstance in fact.
and I tried useinvoke GetLastErrorbut eax = 000000
Make sure your WM_CREATE handler returns 0
Not enough of your code to know.
edit: try using WS_VISIBLE
invoke RegisterClassEx, ADDR wc
eax = 0000C1B4(or else~~~not 000000)-->registered
I am new to masm32 and not familiar with win32 api...

Again I find the problem myself...
I lost some code in WndProc proc~~~
