When translating error messages I get back a pointer to a string (pMsgBuf) that looks like this

The popup menu is created in the dialog’s WM_INITDIALOG message with this code:

Which message (if any) is sent when the dialog is fully shown / drawn / the last child control was created/displayed on a resource dialog? Both the dialog and the child controls are created from a resource inside WinMain().

How to know when the dialog is fully shown / drawn / the last child control was created/displayed on a resource dialog? Both the dialog and the child controls are created from a resource inside WinMain().

I wrote the following code in order to set a hardware breakpoint using Dr0 debug register on a function:

I’m stuck at the pointer offset part. I can get the address offset from “PlantsVsZombies.exe”+002A7758, but when I add 0x68 to this address, I get an incorrect address.
offset=104, which is the decimal value of 0x68.

QueryDosDeviceW returns 0 when called from a source other than the main thread. Why?

(Since this is a standard VCL application, I believe CoInitialize is run automatically)

Is there a need for code blocks followed by a break statement often present in legacy and winapi code, especially when handling the WM_COMMAND message? I have been seeing a lot of the following code in winapi samples:
