>From your earlier post there appears to be an offset of 7000 odd bytes between the allocated location and where you dereference from. This is a really funny value. A small offset (tens of bytes) typically means you have a dodgy class description and a full recompile is in order, but not hundreds of bytes.
Data breakpoints don't need debug symbols to work (they work directly on memory addresses), you may get funny stack traces if you end up breaking into a function that doesn't have debug symbols however. I think more code is in order to debug this, in particular the header and implementation of the class with the problem. - Alfred -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of NuclearFriend Sent: Tuesday, March 22, 2005 1:43 AM To: [email protected] Subject: Re: [hlcoders] ComboBox in VGUI2 Ok, I've never done that before so I tried placing a Data Breakpoint on m_pPrimaryWeaponComboBox. It doesn't come up with any changes to it's value. Yet the value is definately changed when I go to call it again. Could this be because I only have the client dll, server dll and vgui_controls lib in my solution? PS If I set m_pPrimaryWeaponComboBox to it's original pointed memory location in debug mode, it works fine. >_> On Tue, 22 Mar 2005 00:17:08 -0800, Alfred Reynolds <[EMAIL PROTECTED]> wrote: > Drop a memory breakpoint on m_pPrimaryWeaponComboBox (I,e its address > for 4 bytes) and see what changes it. > > - Alfred > > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of > NuclearFriend > Sent: Monday, March 21, 2005 11:56 PM > To: [email protected] > Subject: Re: [hlcoders] ComboBox in VGUI2 > > Oops. > > m_pPrimaryWeaponComboBox[CLASSLOADOUT_RIFLEMAN]->AddItem("M1 Garand", > primaryweapon); > > is now > > m_pPrimaryWeaponComboBox->AddItem("M1 Garand", primaryweapon); > > Just didn't want any unnecessary confusion. > > On Tue, 22 Mar 2005 18:55:07 +1100, NuclearFriend > <[EMAIL PROTECTED]> wrote: > > Ok, I added the vgui_controls lib to my project and got it debugging. > > Which led me to discover that it isn't a problem within the control > > itself, rather a problem with the pointer to the control.
