winforms - Why might I be unable to create an instance of System.Windows.Forms.Form in C#? -

-

मेरे पास एक आंतरायिक समस्या है, जहां मैं System.Windows.Forms.Form वर्ग का एक उदाहरण मेरे C # पुस्तकालय में नहीं बना सकता। मैं अपने कार्यक्रम में अपवादों को लॉग करता हूं, लेकिन दुर्भाग्य से इस समस्या के लिए कुछ भी नहीं दर्ज किया गया था यह प्रासंगिक नहीं हो सकता है, लेकिन मेरी लाइब्रेरी, जिसे COM के माध्यम से बुलाया जाता है (यानी कोई मुख्य विधि नहीं है)।

इसलिए मैंने एक परीक्षण अपवाद फेंक दिया, और इसे पकड़ा गया और सफलतापूर्वक लॉग किया गया - इसलिए मैं सोच रहा हूं हो सकता है कि संदेश लूप में कुछ गड़बड़ हो रहा है?

अपडेट 1

निम्न कोड का उपयोग करके थ्रेड में बनाया गया है, जिसके पास अपार्टमेंटस्टेट .STA सेट। 

  someForm = नया फ़ॉर्म (); SomeForm.Visible = false; SomeForm.Text = "हैलो वर्ल्ड!";

यह सिर्फ एक अनुमान है, क्योंकि आपने कोई कोड और थोड़ा संदर्भ प्रदान नहीं किया है, लेकिन क्या आप अपनी प्रविष्टि बिंदु पद्धति ( मुख्य ) पर STAThread विशेषता को याद नहीं कर सकते हैं? यह WinForms ऐप के लिए आवश्यक है जो कॉम का उपयोग करते हैं।

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
