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।

wpf - Line breaks and indenting for the XAML of a saved FlowDocument? -

-
Is there a way to format XAM generated when a flow document is saved? Currently, all of this is run simultaneously in one line, and I want to break it into my elements, with line break and indenting it makes it a little easier to read. Here is the code I'm using to save a FlowDocument in a WPF RichTextBox as a XAML file: // entire document around TextRange textRange Create a TextRange side = new TextRange (myRichTextBox.Document.ContentStart, myRichTextBox.Document .contentEnd); // save the file using the file (file stream fs = file. Create (filename)) {textRange.Save (fs, DataFormats.Xaml); } Savings work fine, but as I mentioned, JPAM has been generated, all this goes together, no indentation or line breaks for its various elements Is: & lt; Section xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation" xml: space = "preserve" Tekstelinement = "left" Lainhait = "auto" Hashipineshn = enabled = "false...

gtk - Python Window Resize -

Using Python + PyGTK Is there a signal / event way to change the window size? If so, then what is the easiest way to implement and use this signal. There is also one, so it answers the signal. Here's the minimum sample code: import gtk def (window): print 'I have resized'. W = gtk.Window () w.connect ('check-size', has been changed) w.show () gtk.main ()

I'm developing an application that either the incoming data on the PC and then when I'm trying does it decodes the data to use the software with any sniffing have been stored in the dB and I can read it myself ... but my code .... this came in a format like 1651589240214931398151442251437622947132917620011138147205162160411201699123179148781675713921035101183865895219106213196222741589715384652061681391901278671232822552717812424975221242 11517622131122113236255230254211206911242051832545515823012124925217318223920523316923122925514321122343602492471242 ........ I have tried to use this System.Text.Encoding.ASCII.GetString (tcpHeader.Data) and it is working fine. But when I run it and wait for data (this is in XML format) I have found in many packages that it is difficult to read it again ... What should I do? Do I have to collect data from every packet, then add all to get the whole message? Or there is a library to do that in .net
