.net - Entity Framework 6 error: Unable to update the EntitySet 'table1' -


पूर्ण त्रुटि है: 

  EntitySet 'table1' को अपडेट करने में असमर्थ क्योंकि इसकी एक परिभाषित करने वाला और कोई भी & lt; InsertFunction & gt; तत्व & lt; संशोधनफ़ंक्शन मैपिंग & gt; में मौजूद है मौजूदा ऑपरेशन का समर्थन करने के लिए तत्व

आस-पास देखकर ऐसा लगता है कि यह त्रुटि table1 पर प्राथमिक कुंजी की कमी के कारण होती है। मैंने अपनी .edmx फ़ाइल और SQL सर्वर में तालिका की जाँच की है और दोनों दिखाते हैं कि प्राथमिक कुंजी निर्दिष्ट है। यदि आप एडीएमएक्स का प्रयोग कर रहे हैं तो परिभाषित करने वाले डेटाबेस को डेटाबेस के विचारों के लिए परिभाषित किया जाएगा।

और ईएफ केवल एक-भाग के रूप में दृश्य से बनाए गए EntitySet का इलाज करेगा। यदि आप अपने डेटा में हेरफेर करने में सक्षम होना चाहते हैं, तो आपको संग्रहीत प्रक्रियाओं को मैप करने की आवश्यकता होगी, जिसका उपयोग सीयूडी (बनाएँ / अपडेट / हटाएं) संचालन के लिए किया जाएगा।

c++ - How to load a bitmap from file into the samples buffer -

I am trying to add text to the bitmap obtained from the DirectShow filter. First of all I tried to use gdiplus, but that was not working so now I just call a net program that connects to bitmap. The problem is that I do not know how to reload the bitmap from a file into buffer samples in a direct save. Here is my code: Bitmap BMP (640, 480, 2560, 1379773, Newbuffer); // save clsid pngClsid; GetEncoderClsid (L "image / PNG", & amp; pngClsid); WCHAR * file = L "D: \\ temp \\ sample.bmp"; Bmp.Save (file, & amp; pngClsid, NULL); Std :: string command ("D: \\ yourcontrol \\ bitmapDraw.exe D: \\ temp \\ sample.bmp \" test text \ "D: \\ yourcontrol \\ out.bmp"); // Heripal system (command.c_str ()); // Load Bitmap BMP 2 (D: \\ Your Control \\ Out.bmp); How do I forward bitmap from file to sample? Media samples are a part of the agreement between filters on specific pin connections. You usually do not load media samples until y...

javascript - How to get MySQL query result returned using $.ajax -

I'm trying to update is a JavaScript, when you hover over an image, a devi Floats near your mouse, this information is stored in an .js file as an array, for example. text [0] = ["image 1", "data1"] text [1] = ["image2", "data2"] In the past, if the array change / add / delete the data it will need to upload a new copy .js file, if the data was attached / deleted, then the new image needs a change in .dwt file Which can update each file using the .dwt file as the main template, which can result in 20+ pages They are uploaded I thought that I can automate this record by using the database and using the database if they are active and use only mysql queries which are active, such a black app The database can be added and disabled, thus eliminating the need for every soft upload of the file. To do this, I had planned to store the information in the database and create the above array based on the results, by researching how to us...
