explain your program with more detail.

for example i add a textbox .. but when i run the program that textbox doesn't appear ...

 

[ahmad1954]

is this problem occur only on that program or any program?

 

[amintlk]

it occur for only program .. and it didn't happen for other

if possible, put your code here so we can test it.
