Pointers to arrays..? a[spaz][how_what][i]?

Code:

---

UINT ExtractIconEx(         
    LPCTSTR lpszFile,
    int nIconIndex,
    HICON *phiconLarge,
    HICON *phiconSmall,
    UINT nIcons
);

---

Okay, I have a pointer to an array of icons being passed out by phiconLarge, and phiconSmall. How do I move through the array?

I'm actually going to be trying to do this in C#

Code:

---

                #region Win32 API (UnManaged)
                [DllImport("User32")]
                private static extern bool DestroyIcon(         
                                IntPtr hIcon
                        );
                [DllImport("Shell32")]
                private static extern uint ExtractIconEx(         
                        LPCTSTR lpszFile,
                        int nIconIndex,
                        IntPtr *phiconLarge,
                        IntPtr *phiconSmall,
                        uint nIcons
                );
                #endregion

---

Also, does anyone know the values for these. To retrieve the dimensions of the large and small icons, use the function with the SM_CXICON, SM_CYICON, SM_CXSMICON, and SM_CYSMICON flags.

Code:

---

        #region Bit Flag Enumerations
        /// <summary>
        /// To retrieve the dimensions of the large and small icons, use the function with the SM_CXICON, SM_CYICON, SM_CXSMICON, and SM_CYSMICON flags.
        /// </summary>
        [Flags]
        enum SM
        {
                SM_CXICON,
                SM_CYICON,
                SM_CXSMICON, 
                SM_CYSMICON       
        }
        #endregion

I don't have the needed header on my system to look it up.

I know this could be an API or C# thread, but I thought who better to ask than the experts... On the C# side of things though. Will releaseing the System.Drawing.Icon I plan to load from my Icon Handle sufice or should I call DestroyIcon? Or could I say open the icon from the handle draw it into a new managed icon and then destroy the icon I first opened? I'm planning to Open the Icons and throw them into an ImageList.

anybody?

The best advice I can give you for getting the values of SM_CXICON and other defines is to create a very small c++ program just for that purpose. That's the way I did it when I programmed in c#. Download Dev-c++

I believe if you create a .net Icon from a HICON the .net Icon is a copy of the HICON and therefore you need to destroy both Icon and HICON. DestroyIcon for the HICON and the .net way for the Icon.

In c# I don't know how you would deal with an array of HICON's. I assume like you would in c++ use []- indexing.

Thx for the info. I don't know why I don't have all the headers avaliable I have vc7 installed..... I have them all in one of my stacks of cd's somewhere.

I have never made a c++ project that was complex enough to have pointers to arrays so I wasn't sure if it was [accessor] or if you had to create an object of some kind from the pointer to access the memory. I was trying to decied if I needed to byte shift or not. I know bit shifting a pointer can behave in strange ways.

I'm still getting the hang of DllImport also; it is a bit tricky. Some things you have to explicitly set IDL for type conversion and in/out some you don't...
