i hv facing problem of couldnt get the value from the raise event !!! anyone can tell me what is the problem??? the problem is in the Form A part

kenny_oh

I suggest you first try events without the timer and stream reading etc. Just instantiate a subform from the main form, click a button on the subform and make it raise the displayMessage that you'll catch and display in a simple textbox on the main form. Once you're discovered the instricacies of events you can then try it with timers, streats etc.

i hv make some change on the code where can display the form but hang it half way.....cannot display complete!! dont know y....bcoz i hv follow everything and at the event handling load message there should be the main problem!!

the raise event and event handling doesnt hv any problem...can get the value pass from the raise event...but cannot load the form completely.....hang half way.........pls help me, my homework deadline near, i need to solve this task but i try many method liao.......pls!!!
