GDI Leak for ImageList_LoadImage() method

Question

Hi,

I am using following code to load images into HIMAGELIST structure which interns load image into Listview Header.

After using function i am removing images from HIMAGELIST.

I observed in task manager that during "ImageList_LoadImage" functiona call system increase 4 GDI object and while removing 

it does not decrease it.

HIMAGELIST imageList=ImageList_LoadImage(_Module.GetModuleInstance(),MAKEINTRESOURCE(IDB_CHECKBOX),

                              16,16,RGB(255,0,0255),IMAGE_BITMAP,LR_LOADTRANSPARENT);

HWND pHead=ListView_GetHeader(GetDlgItem(IDC_LST_LEG));
ImageList_SetBkColor(imageList,COLORREF(0xFF00FF));
HDITEM hdItem;
Header_SetImageList(pHead,imageList);
hdItem.mask = HDI_IMAGE | HDI_FORMAT;

...

...

 if(imageList){

ImageList_Remove(imageList,-1);
imageList=NULL;
}

Please guide me for removing GDI leaks for HIMAGELIST.

Thanks and Regards,

Deven

Thanks Viorel

It solved my problem

btw one more thing is when i am using following statement it consume 4 GDI objects.  I am having doubt that whether it releases properly or not.

ListView_SetExtendedListViewStyle(ghw,LVS_EX_CHECKBOXES| LVS_EX_GRIDLINES|LVS_EX_GRIDLINES|LVS_EX_FULLROWSELECT);

I am using LVS_EX_CHECKBOXES hence it occupies 4 GDI objects and after scope it was not able to clear all GDI objects as it shows 1 GDI object leak in task manager.
