mysql - How to dynamically change the name of column in the sqlstatement to be used for retrieving data using a combobox -

-

I want to change the name of my column dynamically all the time, whenever I select the same item name as the column Use the Cmbcategory combo box then use it to move your data into cmbparts comboBox. Is this possible?

This is my sample code: 

  public sub cmbpartfill () sqlstatement = "select '" & amp; Cmbcategory.Text & amp; "Connect to Tblparts" (command) = New MySqlCommand (sqlstatement, connection) Reader = command.ExecuteReader while the reader. Read cmbpart.Items.Clear () cmbpart.Items.Add (reader.Item (0) .ToString) while finished disconnect () and sub   
 I appreciate any help thank you .   
 
 
 This will work I think ..............    sqlstatement = "Select" & amp; Cmbcategory.Text & amp; Edited by "Tblparts"   
: Just try not to believe me ............  
  sqlstatement = " ["& Amp; Cmbcategory.Text & amp; "] From Tblparts"

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...
