Binary files and the file system object do not mix fabulous adventures in coding
In the Japanese code page, just-plain-chr E0 is not even a legal characterso Chr will turn it into a zero. COM is possibly one of the worst psuedo technologies that ever existed. I have been asked many times over the years if I know of a scriptable object that can read-write true binary options in trading platform webtrader and your mobile phone files in all locales. Exposing a straightforward array of bytes on disk is only the very first step. Think I'll try your approach when I've got this one up and running.
Invoke provided by the operating system will turn the binary string into a byte array for you. Recordset is quite popular in… certain communities. Actually it says a bit earlier in the article that on the Python side, IDeviceItem is a class.
Additional calls to AddRef and Release are only necessary if the user makes copies of the reference to the object. In VBScript there is no way to create a byte array. April 21, at March 14, at I guess this also relates to encoding.
And it does all this using a standard that was created almost 20 years ago. I learned what a metaclass was before I had fully mastered list slicing syntax. In the process, it unexpectedly creates an instance of IDeviceItem. After the first Release call, the COM object is considered deleted. Content for item in contents:
Further digging will reveal that one of the unknown types is an enum, but the other is another struct involving more unknown types. Text files are more than just binary files that can be interpreted as text. Please don't do that.
How do you handle seeking? Remember Me On This Computer. March 23, at 1:
You have to think about the real-world problems that people are going to have to solve with this tool, and there are a LOT of different scenarios for binary files. However, there are two main factors. Then I just use charCodeAt x. Let me give you an example that clearly fails.
Text files have to conform to certain rules to ensure that they can be sensibly interpreted as text in the local code page. The wrappers then proxy the method calls into an actual COM object that was instantiated under the covers, wrap the return values in Python types, and return them to you, transforming returned error codes into Python exceptions along the way. This slightly simplified sample code allows access to the contents of a camera attached to the computer. Tried searching for ways of getting around this, but failed Hey, found a nifty widget while fiddling.
