WinSpy requires Visual Studio 2010, and supports win32 and win64 builds. Use the IDE to build winspy, or the build/build.bat commandline script to build and package a zipfile for distribution

winspy's Issues

Error x64 version.

x64 version error access denied.

static LRESULT CALLBACK URLCtrlProc(HWND hwnd, UINT iMsg, WPARAM wParam, LPARAM lParam)
{
PAINTSTRUCT ps;
HDC hdc;

    URLCtrl *url = (URLCtrl *)GetWindowLongPtr(hwnd, GWLP_USERDATA);
    WNDPROC oldproc = url->oldproc;

CaptureWindow.c mispelled

Just pointing out in the SRC file, the CaptureWindow.c file is mispelled as CatpureWindow.c.

Size bloat in recent versions

The size from 1.7.1 to the current version is almost double. I assume this is mostly because of a newer compiler version but it should be investigated which switches it will still accept to keep the size down (win98? 512 alignment?).

Hi, I am here to say thank you for Catch22 blog!

Hi James Brown,
I am a self taught hobby programmer who like to play with Windows API. I like to read & learn more about windows internals. Thus I reached your blog Catch22. It seems a treasure for me. Thank you for all your effort on that blog. I created gui library with win api for 7 languages. (D, Odin, C3, Nim, Nelua, Python & Autoit). Reading the source for ReactOS was the game changer for me. It helped me lot. Keep up the good work.

Delay window acquisition option

Somewhat just like with screenshot tools, it may happen that the mere presence of your own window on the screen is enough to spoil the things you wanted to capture in the first place.
So, it would be nice if you could add (say) a 5 seconds delay option in the settings.
