c# - How to know when scrollbar position in the end -

-

I have the GridControl (DevExpress) form, in the end I have some method in the position of the vertical scrollbar I want to call. Is this possible? Thank you.

Edit My solution (does not solve the exact question, but is a good job for me): 

  zero gvDisplay_TopRowChanged (object sender , EventArgs E) {if (gvDisplay.IsRowVisible (gvDisplay.RowCount - 1) == RaouzibileState.Visible) {_lastFocusedRowHandle = gvDisplay.RowCount; LoadNextPortionOfData (); }}    
 
 
 I have not used devexpress before, but about handling it The way to go should still be the same or similar, because you still need to create your extended event. What is done for the default forms of the following windows, if DivXpress expands on it, then there should be no problem.  
 This will be handled by a trigger event. The component class you are using should be a scroll event, this event is called when the position of the scroll bar changes if you create a new component class and you get it from the component class If you want you can add features that you want. In this new component category, scroll down the event to check the value property of the scrollbar. While using this new component class it still has all the functionality that was original, but now with the new features you added.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
