Vista specific CToolBar problem

[Manu Dev]

Hi All, I have an old vc++ application which was running perfectly fine on Win NT and Win XP. (I use VC++ 7 to build it) Now i am running it on Vista. While opening one perticular view it throws an unhandelled exception and simply dies. After debugging I found that the exception is being thrown when i try to add buttons to my dynamic tool bar. The code structure is : There is a CDynamicToolBar derived from CToolBar class CDynamicToolBar : public CToolBar When I need to instantiates the dynamic tool bar i do something like this

//call my constructor
m_wndToolBar = new CDynamicToolBar (/*reqd parameters*/)
//call create function
if (!m_wndToolBar->CreateEx(this))
{//handel error }
//call my function to load all buttons, bitmaps, etc.
m_wndToolBar->Load();
//continue

Its in the Load() ,where I add the buttons array I am getting the exception in Vista while there is no problem in XP

GetToolBarCtrl().AddButtons(iButtonCount+iSeptratorCount, pAToolBarButton);

I have tried removing the code related to the tool bar and running the view without it on Vista. It gives no problem at all (except,i don't get the toolbar of course) I am completely at loss here... Anyone with ideas /suggestion/ :-D solutions

what! no replies! ;P Anyway the problem is solved. in the line

GetToolBarCtrl().AddButtons(iButtonCount+iSeptratorCount, pAToolBarButton);

pAToolBarButton is an array of TBBUTTON structure where each structure represents a button on the tool bar. It seems that each field in TBBUTTON structure must be properly initialized in Vista. Well this is a good programming practice anyway. But in case you have left the less used fields like TBBUTTON.dwValue uninitialized, it would ignored when you application runs on XP. Where as in Vista you get an exception when you try to add the buttons to your toolbar control.
