Weird error with WC_LISTVIEW

[Longie]

Hi guys,

I'm new to programming in windows so I thought I'd write a simple program to start me off.

I have this code:

HWND hList;
LRESULT CALLBACK WndProc(HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam) {
    /* snip */

    hList = CreateWindowEx(
        LVS_EX_FULLWORSELECT | WS_EX_CLIENTEDGE, WC_LISTVIEW, TEXT(""),
        WS_VISIBLE | WS_CHILD | LVS_REPORT,
        150, 10, 550, 300,
        hwnd, (HMENU)ID_LISTVIEW, hInstance, NULL);

        if(!hList)
          exitError();

        /* snip */

That code works fine on Windows XP (I'm sure it works on most other windows platforms too). hInstance is externally declared and it is the instance of the main window used with RegisterClass().

Now, when I plug in a network cable and run the program, I get error 1400 Invalid Window Handle, but only when I have WC_LISTVIEW there, if I make it TEXT("BUTTON") or something else it is displayed.

I don't understand what is going on, it's all weird. I don't have any network code at all, just CreateWindow() 's and that's it. I have some MySQL backend code in there, but I've taken it out for the time being to see if it was that causing it.

Any help would be greatly appreciated

Are you calling InitCommonControls() (Ex) and specifing the ICC_LISTVIEW_CLASSES for listviews?

You don't need it for buttons but do for the more complex controls.

[Longie]

No I'm not calling it, I tried putting it in, but I kept getting an unresolved symbol for _InitCommonControls(), even though I've included commctrl.h which is weird (in my opinion)

[Longie]

Oh my god, I just checked my libraries I was linking with and forgot to include comctrl32.lib, I'm stupid.

Sorry about that guys. Can't tell I'm new to this :P

shouldnt LVS_EX_FULLWORSELECT be LVS_EX_FULLROWSELECT? just wondering how it compiled.. heh, musta been a typo

[Longie]

Heh, yeah, it was a typo, I'm full of those :P I prefer to re-type most things because that way, if there is a typo, you normally see it, not in this case though, heh
