DevExpress Bars 5 to 6 - BarByName is gone, BarByComponentName not functioning properly. Help?
I use the method to introduce new elements to the bar during run time, when I say BarByComponent name, I mean that I need to invoke the name of the bar into a variable so I can call it whenever I want it, however I suspect this is not the case.
Issue: Instead of introducing the new element, a blank space is introduced instead, when clicked upon it generates an access violation error.
Example of my code:
var
BarX: TdxBar;
begin
BarX := mainBar.BarByComponentName
...
Thank you.

I was using that correctly, but after studying mad except logins I found out the reason for the error..
exception class : EAccessViolation
exception message : Access violation at address 0064BEA0 in module 'RF8.exe'. Read of address 000000A0.
Main ($9c8):
0064bea0 +00000 RF8.exe dxBar 32483 +0 TdxBar.GetItemLinks
006497b5 +00005 RF8.exe dxBar 32483 +0 TdxBar.GetControl
At this exact point inside dxBar.pas:
function TdxBarItemControl.GetItem:
begin
Result := GetItemByLink(FItemLink)
end;

end;
Would you test following code please and show what's the result:
var
BarX : TdxBar;
Found : Boolean;
i : integer;
begin
Found := False;
for i := 0 to MainBar.Bars.Count-1 do
begin
if MainBar.Bars[i].Name = 'barMenuList' then
begin
Found := True;
//BarX := MainBar.Bars[i];
break;
end;
end;
if Found then
Showmessage('barMenuList found')
else
Showmessage('barMenuList not found')
end;SOLUTION

That's not the origin of the error, this is:
try
dxbarManager.LockUpdate := true;
DeleteMenus;
RecreateMenus(mainBar);
Finally
try
dxBarManager.LockUpdate := False;
Except
end;
end;
try
dxbarManager.LockUpdate := true;
DeleteMenus;
RecreateMenus(mainBar);
Finally
try
dxBarManager.LockUpdate := False;
Except
end;
end;

Update or refresh does not exist. Do you have msn? I have separated its and bits of the parts where debugger accused the error. I do not wish to post it here.
ASKER
I'll accept your msn as a solution, and then we can go on from there.
ASKER
Issue unresolved, going to be doing some debugging to get to the bottom of it. Might post another question later.
Your question is not very clear
However yo need to test the validity of the BarX
Assuming MainBar is type TdxBarManager
var
BarX: TdxBar;
begin
BarX := MainBar.BarByComponentName
if Assigned(BarX) then
begin
//do your stuff
