 How to switch Main form to other form? Dear all, My application has two form, frmMain and frmTest. When I try to change from
frmMain to frmTest.
.
.
frmTest.show
a=abc+abc
.
.
Then frmTest has been show. However, frmMain continous to do his job, such
as "a=abc+abc".
How to stop frmMain and do the frmTest program first?
and continous frmMain program after frmTest program has finished.
Please advice

How to switch Main form to other form? The process depends on what you are doing in frmTest. Presumably you are showing the form in order to get some user response, so it's not just a matter of creating a function to return a value. The point at which you show frmTest in frmMain should be the end of a
procedure, such as cmdRunTest_Click. Processing in frmMain will stop at the
end of the procedure, unless additional events occur.
frmTest will then have a procedure, such as cmdOK_Click, which the operator
uses to indicate that user input is complete and the calculation can be done
This routine will show frmMain and execute the routine (probably in a
module) that does the calculation and displays the results in frmMain. At
the end of the procedure cmdOK_Click, processing in frmTest will stop.

How to switch Main form to other form? You are dealing with an event-driven programming environment, so conventional program logic flow doesn't apply. Forms don't have beginnings and ends - they have events. At the end of a particular event procedure in frmTest (eg, cmdOK_click) you might want to make frmMain visible for the user - use frmMain.Show. However, if you are talking about the 'end of frmTest' then perhaps frmTest
shouldn't be a form at all but should be a procedure in a module. In that
case, all the previous description does not apply.

How to switch Main form to other form? Hi, Are you aware that the .Show() method of a form will only ever get
called once, and also that you cannot Unload a form only hide it.
To get round this you will need to create your own method called
something like ShowForm(), you can then call this whenever you need
it.
You could also consider having just one form which contains 2 frames
with the controls that you need. You then show/hide the frames.
Hope this helps...

How to switch Main form to other form? Uh? .Show can be executed as many times as required. I think what you mean is that Form_Load() is only ever called once, however many times .Show is executed.

How to switch Main form to other form? Yes, sorry that is exactly what I mean.. This is because forms are not unloaded from memory, and therefore the
Form_Load() event is only executed once as mentioned.
