c# - Connection string int asp error -

-

मुझे लाइन 20 में त्रुटि है यहां त्रुटि रेखा है:

int temp = कन्वर्ट .oInt32 (com.ExecuteScalar ()। ToString ());

मेरे कोड के लिए पृष्ठ:

पेज त्रुटि जो दिखती है:

त्रुटि कहती है:

वर्ण स्ट्रिंग के बाद खुला उद्धरण चिह्न। "

आपका एसक्यूएल कमांड है: 

  स्ट्रिंग चेकयूसर = "सिस्टममेम्बर इनफॉइस से गिन (*) का चयन करें जहां यूजर नेम =" + टेक्स्टबॉक्स यूजरनाम। टेक्स्ट + "'';

यदि आप अपनी स्ट्रिंग देखते हैं, तो आप देखेंगे कि आपके पास अपने WHERE खंड के अंत में एक उद्धरण चिह्न है, लेकिन शुरुआत में नहीं।

आपका जहां क्लॉज को और अधिक दिखना चाहिए: 

  जहां उपयोगकर्ता नाम = '' + टेक्स्टबॉक्स उपयोगकर्ता नाम। पाठ + "'";

कृपया ऐसा प्रश्न भी नहीं करते यह, वे करने के लिए अतिसंवेदनशील होते हैं।

I want to change the color of the surface on the basis of another value (an ID) that is considered discrete (hence I In the simplified example given below, I have prepared a field with 3 different IDs: 0 / red on left 2 / blue 1 / green left But with the code below, I have some strange behavior on the border between red and blue (green Point) I think this is probably due to an interpolation! Code: import from import mlab np # np # my dataset -simplified-x, y, z = np.mgrid [-3: 3: 100] H, -3: 3: 100h, -3: 3: 100 h] value = NP. SQLT (x ** 2 + y ** 2 + z ** 2) # My color value: Volume is divided into 3 sub-versions taking colorvalues ​​with X = np.empty (values.shape) colorvalues [0:33,:,:] = 0 colorvalues ​​[33:66,:,:] = 2. Look [66:,:,:] = 1 src = mlab.pipeline.scalar_field (value) src.image_data.point_data.add_array (colorvalues.T.ravel ()) (1) .name = 'MyID' src.image_data. point_data.update src.image_data.point_data.get_array () # surface, contour = mlab.pipe...
