asp.net - how to find the max id from a generic list -

-

I am getting a collection of data in the object of the list and I want to get the maximum id.` from this list > objinfo dim list (as AlbumInfo) = objPhotos.GetPhotos_Alb_ID (Me.ModuleId, hdd_AlbID.Value) dim as the string Photo_Image = "" dim string string = photos_isages & amp; Fu_Photo.PostedFile.FileName.Substring (fu_Photo.PostedFile.FileName.LastIndexOf () ".") If objinfo.Count & gt; = 1 then Photo_Image = Convert.ToString (hdd_AlbID.Value) + "_" + Convert.ToString (objinfo .emem ("0"). Photo_Id +1) Otherwise Photo_Image = Convert.ToString (hdd_AlbID.Value) + "_" + Convert.ToString ("1") end then

Returns Convert.ToString (objinfo.Item ("0"). Photo_Id +1) The "0" id, but I want to get the ID of the last item.

OK, you specified maximum in the title, and In the last question, here are both:

Maximum: 

  Photo_Image = hdd_AlbID.Value.ToString () & amp; "_" & Amp; _ Objinfo.Max (function (o) o.Photo_Id) _ .Photo_Id.ToString ()   
 Last:  
  Photo_Image = hdd_AlbID.Value.ToString () & Amp; "_" & Amp; _ Objinfo.Last (). Photo_Id.ToString ()

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...
