Showing tag results for Code

A customer was having trouble with their shell namespace extension: When we click the [+] button next to our shell namespace extension in the folder tree view, the tree view shows both files and folders, even though it's supposed to show only folders. Our does return the correct values for (including it for the folders and omitting it for the n...

nick_journals demonstrates some confusion about names in source code and their relationship to runtime behavior. A topic I am particularly interested in is the naming of controls, how it works... Every control gets a name from a developer...via the IDE (e.g btnOK) When using this function: GetWindowLong(handle,GWL_ID) it doesn't return the n...

We saw last time that the function waits only once for a process to go input idle. Even if the process later stops processing messages, will return immediately and say, "Yeah, he's idle." The way a process is determined to be input idle is that it is waiting for user input when there is none. This translates into the process sitting in a functi...

The function waits for a process to finish its initialization, which is determined when it reaches a state where it is just sitting around waiting for messages. The documentation for doesn't even get around to the initialization part until the Remarks section. If all you read is the one-sentence summary, Waits until the specified process is wait...

In the documentation for delay-loading, there's a remark that says that the call to can be avoided if there is binding information. A customer who received the explanation of why you can't delay-load pointed out that paragraph and asked whether this means that you can delay-load if you bind to it. (Getting around to answering this question wa...

Last time, we saw how hinting is used to speed up the resolving of imported functions. Today, we'll look at binding. Recall that the module loader resolves imports by locating the function in the export table of the linked-to DLL and recording the results in the loaded module's table of imported function addresses so that code from the module ...

Binding and hinting are two types of optimizations to improve the load-time performance of a module (executable or DLL). We'll start with hinting, then look at binding, and then look at how it affects delay-loading. The import table for a module contains a list of DLLs and a list of functions from that DLL which the module wishes to link to. The b...

Because it's still talking to the old parent.

One of the five things every Win32 programmer should know.

The interface is a simpler form of context menu extension which takes care of the annoying parts of so you can focus on your area of expertise, namely, doing the actual thing the user selected, and leave the shell to doing the grunt work of managing the UI part. I've never needed a scratch shell extension before, so I guess it's time to create...
