Question

Well, I’m using UpdateResource to embed a file to an executable file.
It works correctly but I want to know whether or not it is possible to show the update progress using a ProgressBar?

Answer 1

Since there’s no callback function passed in, there’s no way to receive progress information. In addition, UpdateResource doesn’t actually update the file until you call EndUpdateResource, so during calls to UpdateResource there’s actually no progress to report anyway.

From MSDN:

An application can use UpdateResource repeatedly to make changes to the resource data. Each call to UpdateResource contributes to an internal list of additions, deletions, and replacements but does not actually write the data to the file indicated by hUpdate. The application must use the EndUpdateResource function to write the accumulated changes to the file.
