TS_ExprCtrl_Create object handle

[bruno_p]

Hello,

I'm using LabWindows/CVI 9.0.1 and TestStand 4.1.1.

When I'm debugging my CVI DLL with the resource tracking tool, I can see that the TS_ExprCtrl_Create function creates 3 object handles.

When the panel is discarded, 2 handles are automatically discarded.

But there is still 1 handle that is never discarded.

Is it a memory leak or am I missing something ? Should I use a function to release the last handle ?

It's a memory leak in TS_ExprCtrl_Create. What's happening is TS_ExprCtrl_Create is calling TS_ExprCtrl_CreateActiveXControl which calls TSUI_ExpressionEditGetBorders to get an object handle to the Borders interface. But CA_DiscardObjHandle is not being called on the borders object handle.

I've created a bug report (ID 177213) to fix this.

Just to clarify, you could add the call to CA_DiscardObjHandle in TS_ExprCtrl_CreateActiveXControl yourself to have a fix for the leak now.
