c# - What typeof(Page) Am I Navigating From? -

-

मूल पृष्ठ टेम्पलेट में, विधि नेविगेशनहल्पर_लोडस्टेट (ऑब्जेक्ट प्रेषक, लोडस्टेट एवेन्टएआरजीएस ई) {} ।

यदि (sender.GetType () == प्रकार (पिछला पृष्ठ)) {} काम नहीं करता है!

मेरा प्राथमिक उद्देश्य यह जानना है कि कोड में साफ से मेरा डेटा कहां से आ रहा है।

आपका विधि नेविगेशनहेल्पर_लोडस्टेट (ऑब्जेक्ट प्रेषक, लोडस्टेट ईवेंट एआरजी ई) {} को नेविगेशनहाल्पर द्वारा बुलाया जा रहा है और प्रेषक पास के रूप में काम नहीं करेगा नेविगेशनहाल्पर - कोई भी जानकारी नहीं है जिस पर नेवीगेशन पृष्ठ शुरू हो गया है।

मुझे कोई ऐसी संपत्ति नहीं दिखाई दे, जिसमें आप यह जानकारी पढ़ सकते हैं, लेकिन आप निश्चित रूप से अपना पिछला प्रकार एक पैरामीटर के रूप में: <पूर्व> // नेविगेट करना: फ़्रेम। नेविगेट (टाइपफ (पेज 1), this.ToString ()); // लक्ष्य पृष्ठ में: संरक्षित ओवरराइड शून्य ऑन नेविगेट किया गया (नेविगेशन एवेंट एर्ग्स ई) {यदि (ई.पैमिटर == टाइपफ (मेनपेज) .ओस्ट्रिंग ()) डीबग करें। Wrightite ("पिछला मुख्य पृष्ठ था"); }

I do not know how to use mysqli_result like in the past. Is this OK? How is right WHERE status = 'popup' and creditsp> = 1 and (CH) from $ res = mysqli_query ($ con, "SELECT` id`,` usrid`, `url` site Lt; cf || cf = 0) sequence by rand () border 1 "); $ Urll = mysqli_result ($ res, 0, "url"); $ Ownerid = mysqli_result ($ res, 0, "Elixir"); $ Citid = mascile_salt ($ res, 0, "id"); Use fetch_assoc on the results: $ line = $ res-> gt; Fetch_assoc (); $ Urll = $ line ['url']; $ Owner = $ line ['nectar']; $ Site id = $ line ['id']; If there are more than one line, then: while ($ line = $ res-> fetch_assoc ()) {// process $ Line}

I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...
