    Performance - What really matters?

    in General

    Posted

    Hello guys!! How you doing?

    I've been testing some small applications to learn more about performance with Unigui but i want to know from you guys what is the best pratice to consuming less resource of the server side?

     

    I tested 3 cases with 500 records with one DBGrid:

    • Consuming an API and saving the data in a TFDMentable.
    • Direct connecting in the local database with TFDQuery.
    • Direct connecting in the local database but saving the data in a TFDMentable.

     

    Using the stress test tool in all the 3 cases, the consuming off resources is pretty much the same. The big deal here is that with direct connecting the server side holds the memory until i close the TFDQuery and in the other tests i close the TFDQuery immediatly fetch the records on the TFDMentable realising the memory more fast than the others.

    You can try something like this: 

    
function window.afterrender(sender, eOpts)
{
    var me=sender;
    me.dropTargetBody = Ext.create('Ext.dd.DropTarget', Ext.getBody(), {
        ddGroup: 'D1',
        notifyDrop: function(source, evt, data) {
            ajaxRequest(me, 'dropped', ['gridname='+source.view.grid.uname]);
        },
        notifyEnter: function() {
            
        }
    });
}
    
procedure TMainForm.UniFormAjaxEvent(Sender: TComponent; EventName: string;
  Params: TUniStrings);
begin
  if EventName = 'dropped' then
  begin
    //UniDBGrid1.SelectedRows.Delete;
    //Additional checks: is as
    ShowMessage((FindComponent(Params.Values['gridname']) as TUniDBGrid).Name)
  end;
end;

     

    It work's thanks!!!!

    Hello, 

    Can you make a simple testcase to understand the issue? 

    i did it! Thanks for the help but  i have another question, is it possible to get the name of the grid that i drag the record in this code?

     

    Is that the same solution that you answered me above, i just need to get the name of the grid tha i drag the record now. 

    function window.afterrender(sender, eOpts)
{
    var me=sender;
    me.dropTargetBody = Ext.create('Ext.dd.DropTarget', Ext.getBody(), {
        ddGroup: 'D1',
        notifyDrop: function(source, evt, data) {
            ajaxRequest(me, 'dropped', []);
        },
        notifyEnter: function() {
            
        }
    });
}

    Hello,

    Try these approaches.

    Worked on this example:  

    
\FMSoft\Framework\uniGUI\Demos\Desktop\Grid - DragDrop - Custom Handler

    DropToPanel:

    1.UniDBGrid.DragDrop.DragGroup = D1

    ...

    2. UniPanel.ClientEvents.ExtEvents -> 

    
function afterrender(sender, eOpts)
{
    var me = sender;
    me.dropTarget = Ext.create('Ext.dd.DropTarget', me.getEl(), {
        ddGroup: 'D1',
        notifyDrop: function(source, evt, data) {
            ajaxRequest(me, 'dropped', []);
        },
        notifyEnter: function() {
            
        }
    });
}

    3.  

    
procedure TMainForm.UniPanel1AjaxEvent(Sender: TComponent; EventName: string;
  Params: TUniStrings);
begin
  if EventName = 'dropped' then
  begin
    UniDBGrid1.SelectedRows.Delete;
  end;
end;

    DropToAnywhere:

    1.UniDBGrid.DragDrop.DragGroup = D1

    ...

    2. MainForm.ClientEvents.ExtEvents -> 

    
function window.afterrender(sender, eOpts)
{
    var me=sender;
    me.dropTargetBody = Ext.create('Ext.dd.DropTarget', Ext.getBody(), {
        ddGroup: 'D1',
        notifyDrop: function(source, evt, data) {
            ajaxRequest(me, 'dropped', []);
        },
        notifyEnter: function() {
            
        }
    });
}

    3.  

    
procedure TMainForm.UniFormAjaxEvent(Sender: TComponent; EventName: string;
  Params: TUniStrings);
begin
  if EventName = 'dropped' then
  begin
    UniDBGrid1.SelectedRows.Delete;
  end;
end;

        ddGroup: 'D1',

    Hi, 

    Please specify an edition and build of UniGUI you are using. 

    Hello, i'm using the build 1534.

    I found the component but the only way i found to get the data was trough the remote query but remote query is no the solution that i need. I need the possibility to link a datasource to the combobox.

     

    Thanks

    drawing on unimap in runtime

    Hi,

    In the demo, we explained clearly how to create a vector. You will use onMapClick event to create a vector

    Sorry ASLAN i saw the demo but it's still not clear how to draw the vector in runtime.

     

    I tried to use the following code to draw the vector but it's add only one point at time in my map, it's not connect the points and draw the vector. 

    with UniMap1.Vectors.Add do
  begin
    AddPoint(lat, lng);
    VectorType:=mvPolygon;
    with Options do
    begin
      color:= UniColorButton1.Color;
      fillColor:= UniColorButton2.Color;
      weight:= Trunc(UniNumberEdit5.Value);
      opacity:= UniNumberEdit6.Value;
      fillOpacity:= UniNumberEdit7.Value;
      radius:= Trunc(UniNumberEdit8.Value);
    end;
    AddToMap;
    FitBounds;
  end;

    In this case. And with our solution, you can use it like this.

    1. For example, you can use a combobox for select the another component id. 

    
  ...
  YourMainButton.JSInterface.JSAssign('screenshotObjId', [YourCustomComponent.JsID]);
  ...

    2.  

    
function click(sender, e, eOpts) 
{
    html2canvas(document.getElementById(sender.screenshotObjId), {
        dpi: 144
    }).then(function(canvas) {
        var ctx = canvas.getContext("2d");
        ctx.webkitImageSmoothingEnabled = false;
        ctx.mozImageSmoothingEnabled = false;
        ctx.imageSmoothingEnabled = false;
        var myImage = canvas.toDataURL("image/jpeg,1.0");
        ajaxRequest(sender, "getData", ["base64Data= " + myImage]);
    });
}

     

    Sorry, it works but the problem continue =(

    The uniSession.SendFile still send a lot of files to save like if i had a loop im my function.

     

    I think the problem is not in the function, I think is some problem with the uniSession.SendFile command because in the second time that i click de button the Event is call just one time but de UniSession.SendFile keep send the file BEFORE the AjaxEvent be call in delphi.

     

    There is a way to clear the cache or buffer of the session?

     

    SendFile with clientEvents.rar

    Ok, almost there... What if i need to change the 'sender.id' for another component? I need to take a screenshot of a panel not of my button(sender).

    It seems not, what kind of object?

    Any object, i need to set there the object that i want to take the screeshot. How it works ?  When the function was in the delphi click event i just use the code like: MyPanel.JsID or MyButton.JsID.

    How it workd now that i change my function to ClientEvents?

ajaxRequest(sender, "getData", ["base64Data="+myImage]);

     

    A little question: Is this line correct? 

    html2canvas(document.getElementById(PanelCentral.jsID) , { dpi: 144 } )

    If i need to use another component there i just call de name of the component?

    Hello,

    Sorry for the late response.

    One possible solution...:

    1. Remove "JSInterface.JSCode..." from OnClick event 

    
procedure TMainForm.UniButton1Click(Sender: TObject);
begin
end;

    2. You need to move the logic to ClientEvents.ExtEvents... 

    
function click(sender, e, eOpts)
{
  sender.setDisabled(true);
  ajaxRequest(sender, "getData", ["base64Data=teste"]);
}

    3. ClientEvents.UniEvents... 

    
function ajaxCallback(sender, response)
{
    sender.setDisabled(false);
}

     

    Nice, I'm already trying to do that but without success... 

    function click(sender, e, eOpts)
{
  html2canvas(document.getElementById(PanelCentral.jsID) , { dpi: 144 } ).then( 
    function(canvas) { '+
       var ctx = canvas.getContext("2d");      
       ctx.webkitImageSmoothingEnabled = false; 
       ctx.mozImageSmoothingEnabled = false;   
       ctx.imageSmoothingEnabled = false;      
       var myImage = canvas.toDataURL("image/jpeg,1.0"); 
       ajaxRequest('#1', "getData", ["base64Data="+myImage]); 
    } );
}

    Also, your code seems to be "incomplete" 

    
function click(sender, e, eOpts)
{
  ajaxRequest('#1', "getData", ["base64Data=teste"])
}
    
ajaxRequest('#1', "getData", ["base64Data="+canvas.toDataURL("image/jpeg,1.0")])
    
procedure TMainForm.UniButton1AjaxEvent(Sender: TComponent; EventName: string;
  Params: TUniStrings);
begin
  if EventName='getData' then
  Begin
    UniSession.SendFile(UniServerModule.FilesFolderPath+ 'unipdf.pdf');

  End;
end;

     

    Yeh it is incomplete, i just made the example using the html2cavas with the ajaxrequest because the problem only show when i call de html2canvas function. In my main application i convert the base64 image and save on a PDF, after that i send the 'unisession.sendFile'.

    Just focus on the problem, i click one time in the button and the server send me 2 files do download just it.

     

    Thanks in advanced...
