OK, the GitHub link @andrecool-68 provided already pointed to a description of how I did it.
Did not remember that.
What can I say: “Now also available for Notepad++ 64 bit!” :-D

@andrecool-68 I agree, same toolbar button functionality as the build-in Function List toolbar button i.e. indicating active/inactive by changing the button background color.

just found out it only show up as black box when viewing through remote desktop, when i login to the pc physically, it show up fine as my icon.

Move all the files of the plugin into one directory, and nothing needs to be renamed

Regarding the Find Result panel (better later than never)… The command npp_sendmsgex can be used to send a message to a custom window (hWnd). So the trick is to get the hWnd of the Find Result panel’s Scintilla window. Looking through the existing messages in “Notepad_plus_msgs.h”, I don’t see a quick solution, though.

@Alan-Kilborn - That’s very nice, thanks! In that case I think I’ll use 64-bit Notepad++.

Hi all,

The problem was in the code of the compare loader itself.

for (int i = 0; i < iMenuItems; i++)
{
...
GetMenuItemInfo(hPluginMenu, i, TRUE, &mii);
if (!lstrcmp(buffer, L"Compare"))
{
...
int iSubMenuItems = GetMenuItemCount(mii.hSubMenu);
for (int j = 0; j < iSubMenuItems; j++)
{
...
GetMenuItemInfo(mii.hSubMenu, i, TRUE, &smii);

The second GetMenuItemInfo should use the second forcycle index:

GetMenuItemInfo(mii.hSubMenu, j, TRUE, &smii);

The beauty of the code on nulledge is that it is already in Python. But oops, it appears that nulledge has gone 404. :( Maybe my future needs will have VB6 searches involved.
