If we define two variables in vb6.0 as follows<p>dim vara(),varb() as byte 'other types also introduce same problem<p>and there are one function or procedure which defined as<br>public sub sub_a(...,vara() as byte,varb() as byte,...)<br>end sub<p>My problem is that after i call the function or procedure (for example, call sub_a(...,vera,verb,...)) why the compiler tell me the error message, "type mismtach: array or user-defined type expected", in the location of vara(). But, the problem can be sloved by the following defintion<br>dim vara() as byte<br>dim varb() as byte<p>For one words,<br>1. dim vara(), varb() as byte<br>2. public sub sub_a(...,vera() as byte ,verb() as byte,...)<br>3. call sub_a(...,vera,verb,...)<br>will get an error message, but<br>1. dim vera() as byte: dim verb() as byte<br>2. public sub sub_a(...,vera() as byte ,verb() as byte,...)<br>3. call sub_a(...,vera,verb,...)<br>will work!!<p>Can anyone tell me why is the problem happened?<p>Thank you in advance<p>Wen-Gou Lin
