c# - Clarify two columns of the same name -

-

मैं इस प्रश्न हैं: 

  का चयन करें CableNumber, CblType, ApprxmtLngth, ME.EquipmentNumber, ME2.EquipmentNumber, CblStatus, InstallMthd, S.PrdtCd CableId से सी अंदरूनी MajorEquipment मुझे शामिल हों पर C.FromLoc = ME.MEId अंदरूनी शामिल हों MajorEquipment ME2 पर C.ToLoc = ME2.MEId अंदरूनी शामिल हों SupplierInfo एस पर C.SupplierId = S.SupplierId कहां (@CblType शून्य है या CblType तरह @CblType) और (@CblStatus शून्य है या CblStatus तरह @CblStatus) और (@FromLoc शून्य है या ME.EquipmentNumber तरह @FromLoc) और (@ToLoc नल या ME2.EquipmentNumber की तरह है @ ToLoc);   
 जब मैं परिणाम को एक मॉडल में पास करता हूँ, तो मैं यह कैसे परिभाषित करूंगा कि कौन सा  EquipmentNumber  उस चर में जाता है?  
  जबकि ( mySqlReader.Read ()) {CableID_Controller.CList.Add (नई CableID_Model {CableNumber = Convert.ToString (mySqlReader [ "CableNumber"]), CableType = Convert.ToString (mySqlReader [ "CblType"]), SupplierPart = Convert.ToString ( mySqlReader [ "PrdtCd"]), CableLength = Convert.ToInt32 (mySqlReader [ "ApprxmtLngth"]), InstallMethod = Convert.ToString (mySqlReader [ "InstallMthd"]), उत्पत्ति = Convert.ToString (mySqlReader [ "ME.EquipmentNumber"] ) तो गंतव्य = Convert.ToString (mySqlReader [ "ME2.EquipmentNumber"]), स्थिति = Convert.ToString (mySqlReader [ "CblStatus"])}); }   
 क्योंकि  ME.EquipmentNumber  और  ME2.EquipmentNumber  हेडर के वास्तविक नाम नहीं हैं।   
 
 
 विवरण  
 बस कॉलम अलग उपनाम दें ( EquipmentNumber1  और  EquipmentNumber2 ) आपकी क्वेरी में और कोड को  जैसा  ऑपरेटर के रूप में आपको अपने कोड में  ME1  और  ME2  निकालना होगा  
 नमूना  
  CableNumber, CblType, ApprxmtLngth, EquipmentNumber1 रूप ME.EquipmentNumber, ME2.EquipmentNumber EquipmentNumber2, CblStatus, InstallMthd, S.PrdtCd के रूप में चयन CableId सी भीतर से शामिल हों MajorEquipment मुझ पर C.FromLoc = ME.MEId अंदरूनी शामिल हों MajorEquipment ME2 पर C.ToLoc = ME2.MEId अंदरूनी शामिल हों SupplierInfo एस पर C.SupplierId = S.SupplierId कहां (@CblType CblType तरह @CblType शून्य है या) और (@CblStatus है नल या CblStatus तरह @CblStatus) और (@FromLoc शून्य है या ME.EquipmentNumber तरह @FromLoc) और (@ToLoc ME2.EquipmentNumber तरह @ToLoc शून्य है या); जबकि (mySqlReader.Read ()) {CableID_Controller.CList.Add (नई CableID_Model {CableNumber = Convert.ToString (mySqlReader [ "CableNumber"]), CableType = Convert.ToString (mySqlReader [ "CblType"]), SupplierPart = कनवर्ट करें। ToString (mySqlReader [ "PrdtCd"]), CableLength = Convert.ToInt32 (mySqlReader [ "ApprxmtLngth"]), InstallMethod = Convert.ToString (mySqlReader [ "InstallMthd"]), उत्पत्ति = Convert.ToString (mySqlReader [ "EquipmentNumber1"] ), गंतव्य = कन्वर्ट.ToString (mySqlReader ["EquipmentNumber2"]), स्थिति = कन्वर्ट.ToString (mySqlReader ["CblStatus"])}); }

ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

-
I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...

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...

c# - Textbox not clickable but editable -

-
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...
