delphi - How to achieve smaller size of the executable? -

-

After a long time, I have returned after a long time in Delphi and an old release to my client ... < / P>

I know that size has no effect these days, but I have been strangely struck that a unit application, when compiled, 1x084 / 416b executable one and only .pice I wrote the unit, it is 20.8k larger, mostly due to the prosperity of Gai

Usage section is as follows: 

  Windows, messages, SUsUtils, variants, classes, controls, forms, struts, dialogs, ADODB, DB Uses DBGrid, Extra Secrets, DBCTRLs, STCTRL, Grid, Menus, Buttons;   
 I wonder if in any way can I reduce the size of the application to 300-400 or less?   
 
 
     
  1.  
     Did you debug or build a release? (For small size issue it, make sure that optimization is on, debug info is off)   
  2.  
     Did you turn off RTII (DLFA 2010 and above) If not needed? (Size of small EXE.)   
  3.  
     The number of units in the section of your use of your main unit is not a good way to estimate the EXE size, think about it: Vcl There is only a large amount of code, the database layer is another, and the content you write is probably a very small percentage of the X-shaped size.   
  4.  
     To understand your executable size, try JCL Project Analyzer, or read the map file when you turn on the map option. It will tell you what's inside your executable file.    
     It will be silly for many reasons, but for example, you can get a small executable using Delphi 7. Finally when I make an application and I want to minimize it, I think how long it will take, and how much effort will be made to rebuild everything (like with the VCL option) and then I myself I say this

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ... " , Status {console.log ("open site:" + data [index B], position); / * OLD * / indexB ++; page evaluation (function () {// page scrape and an object Return}, function {console.log (result.dataRequest); // here is the problem}); / * new and fixed * / indexB ++} first console Logs it: Open Site: 100 Success Opens Site: 101 Success B Ola Site: 102 Success Opening Site: 103 Success Opened Site: 104 Success Which is good. Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
