Editors IDEs





Development in most programming languages is frequently done with an editor or integrated development environment (IDE). An IDE is a software application that provide comprehensive facilities to computer programmers for software development. An IDE normally consists of a source code editor, build automation tools and a debugger. XCode, Visual Studio, Adobe Dreamweaver and Eclipse are some of the more popular development tools, but an editor or IDE can be anything from simple text editors to sophisticated programs.

I have to modify a Qt Creator project on Windows 7. The compiler/linker uses Visual Studio 2010 Pro SP1. (The debugger works on VS, but not on Qt.)
I debug by adding print statements. I want to be able to debug using a debugger.

I found this page which also leads to subsequent links.

The IT department (one person) is overworked, and this debugger task is considered low priority. Furthermore, the admin has no idea how to get the debugger to work. The lead said that if I can come up with a step-by-step written list of things to do, then he would raise the priority of getting the debugger to work. Statements like "add <...> to Qt screen <...>" doesn't help since IT won't know what to do. Need detailed steps.

Maybe someone has already done this and can provide these detailed steps (supported by links so I can review and ask questions, to help clarify the steps - I get one shot to get this to work). General comments and links without the detailed steps probably won't help the IT guy.

A year ago, I think I saw that we needed a version of SDK (maybe SDK 7.1?) to get the Qt Debugger to work. This SDK is not installed on my Windows 7 workstation, but I am told that we are allowed to install it. In general, we have a list of items we are allowed to install, and anything not on the list is not permitted.

My environment:
Windows 7
Qt Creator 2.6.0 based on Qt 4.8.2
Qt Compiler/linker used is hooked to Visual …

source folder vs folder

In eclipse i created java project call UserAdminProj

I right clicked on above project and selected new "Source Folder" option and gave name mentioned Test.

It created test source folder.

My question is when i right click on the UserAdminProj i see other option with "Folder"

How these two different

I have a live working Django web application on my desktop.
I created a project for it in Pycharm.
What kind of setup do I need to be able to debug  using the current production webserver, settings, etc.
String contactNumber = null;
 contactPhone = String.valueOf(PropertyHelp.getXYZProperties().getProperty("common_support_phone"));//XYZ.properties has common_support_phone=8001234567
            while getting contactNumber from a property file i am getting null.

How does eclipse resolve .property file entries. How it reads them?
how to debug to see correct value 8001234567 comes from it rather than wrong value?
any good end to end examples, resources on this?

please advise
any free tools like xpmspy which is free for generating sample xmls from XSDs and to work with XSLT etc.

I head XMLEdit but i did not see any direct link to download though?

How do you Switch Views within the same Child Frame?  C++ VS2018 15.5.6  I am using the MFC Doc/View Architecture.  I can create new 7 document, as programed.  I have seen several different code examples for do it within the Main Frame, however not within the Child Frame class.  I have created several different CView based classes.  I have added the #include(s) for them in the App.h file header, and this header is included in the ChildFm.cpp file.  It shows up OK as far as Intellisense is concerned.  
// ChildFrm.cpp : implementation of the CChildFrame class
#include "stdafx.h"
#include "TCPG.h"
#ifdef _DEBUG
#define new DEBUG_NEW

// CChildFrame
      ON_COMMAND(ID_VIEW_PLAYERVIEW, &CChildFrame::OnViewPlayerview)
      ON_COMMAND(ID_VIEW_QUESTIONVIEW, &CChildFrame::OnViewQuestionview)
      ON_COMMAND(ID_VIEW_LAYOUTVIEW, &CChildFrame::OnViewLayoutview)
      ON_COMMAND(ID_VIEW_YOURREADING, &CChildFrame::OnViewYourreading)
These are the function declarations for switching the views.  The empty bodies are in the .cpp file.
And all of it compiles OK at this point.  Each view class is filled with all of the necessaries for that class, and works with the CDocument class.
Yet ...  when I add
// ChildFrm.h : interface of the CChildFrame class
#pragma once

class CChildFrame : public CMDIChildWndEx
I want to find, extract, and replace string on a file.

      m1.Lines.Add(Buffer); // no need, just display to evaluate
      (* 1. Get address of given keyword *)
      // i := Stream.PositionOf(myKeyword);   < how to do this?
      (* 2. Stream Replace *)
      // I want to replace MyKeyword with other string

    MS := TMemoryStream.Create;
      MS.SaveToFile(edtTarget.Text + '.mod');
      // save the edited file, is there any other way than using MS?

hello Experts,

i have a DDDW...in which i can type any value.

now i want as soon as i start typing the value it will start showing all the values with those letters.

example: let say in country list i want to search for India and the list of countries are there with A to Z order.
 so what i want is As soon as i start typing I it will start displaying the country list with I alphabate and as soon as i will type IN it will apply filter for IN and same for all the next alphabates.

I recently downloaded the new version of jaspersoft studio (6.5.0) for eclipse.  I used to be able to choose specific dates for a parameter when previewing a report, now if I pick a specific date it treats it as null.  The only values I can get to evaluate to non-null are the relative dates like "DAY" or "MONTH".

Switching to an older compatibility mode doesn't seem to work either.

DATERANGE("2017-12-22") evaluates to null when I preview.
DATERANGE("DAY") evaluates to the correct Date, 2017-12-22.

Anyone have any thoughts?

Edit: Here's the documentations on Jasper's Date Range object: http://jasperreports.sourceforge.net/sample.reference/daterange/index.html

Im trying to add persistent fields (FieldDefs) and then add those fields to Fields. From the start i have only 2 fields:

Id : ftInteger
Name : ftString

When i create a new field "Test":ftString and try to add the new persistent field to "Fields" i get error "Missing dataprovider or datapack". Its a standalone use of clientdataset, no provider. When i then go to the fields editor and try to "add fields", the field dissiperar from field-defs. If i the right click on the cds and select "clear data", and then "create dataset" i get error "invalide fieldtype". If i skip to add persistent fields and just add it as a field, i get error "Catastrophic failure"....

Only way i found seems to:

(1) Manually delete all not persistent fields.
(2) Clear dataset
(3) Add the new persistent field
(4) Add all fields.

Not so very brilliant if i have properties on my fields. Clientdataset looks like it been around forever so i'm surprised it bugs like this, or am i missing someting?

I have searched online and have been unable to find a recent example as to how the eBay API can be called from a recent version of Delphi XE using Indy.

If anyone can post here such a piece of code, I am sure it would save many people a lot of time trying to figure it out.

Many thanks!

I am trying to use an SDK that is developed as a .NET DLL in Visual C/C++ in a Java development environment using Netbeans.

I want to use JNA and have been using the JNAerator to generate the java classes using the .h file of the library that I have received with the SDK. I think I have overcome the compile errors in the library and am now trying to get a sample program running. But when I call the functions it gives me all kind of errors. First of all the functions need to be called with pointers to structures that are being filled. I am not able to get java compiled without warnings/errors.

Is there anybody that has experience with using JNA and C/C++ dlls in Netbeans?

Any ideas?
I had this question after viewing Open a file from Powerbuilder using Windows default associated program.

I have used ShellExecuteW in my powerbuilder application to open any type of files on double click. The function/application works absolutely fine while running through powerbuilder, but terminates when i run thro PBD and EXE  with 0007 termination error-Unresolvable external linking reference to ShellExecutew .

Please let me know if i am missing anything..

below is my code

 li_rtn =GetFileOpenName("Select File",docpath, docname ,"DOC", &
                  + "All Files (*.*), *.*" )
string ls_filename, ls_null

//declared this external function-so calling it here
//ShellExecuteW( handle( THIS ), "open", ls_filename, ls_Null, ls_Null, 1)

In global external functions of userobject,have declared it as below
FUNCTION long ShellExecuteW( ulong hWnd, string Operation, string lpFile, string  lpParameters, string lpDirectory, int nShowCmd ) LIBRARY "shell32.dll" Alias For "ShellExecuteW"
I have created a number of forms in my database.  What I am trying to do now is create the same record in three other forms when I add a new record to them.  It might have been easier if I had started with subforms from the beginning.

Bottom line, when I create a record in the main form, I want the other forms to use the same record id.

The forms appears to be operational by themselves.

    i'm working on powerbuilder 12.5 and i'd a problem trying to handle a calendar.

i did a stored procedure with: name, addres, city, state, dates, d_with, subject, notes, etc.
'dates' could be every 30 mins o an hour (and i'll need this as row or as column, the other one (row or column) must be 'state')
i cant hardcode 'dates' (remember, this could be every 15 mins, 30, 45, 1 hour, etc.)

i want to show this data on a crosstab like:
* column as 'dates',
* rows as 'state'.
* in the intersection, the value should be 'name','d_with' (the another person), and 'notes'.

as i said, i could do the crosstab on the other way ('state' as column and 'dates' as rows), but the 3 values have to be the same.

here i have 2 problems:
1° i cant handle properties as background, visible, etc using the other data received from the sp.
2° i cant put the 3 values on the same position (properties -> x axis). if i do, when i retrieve, the datawindow shows me as staircases.
i thought put an computed field, but it make as another column outside from then dates column.
Hi, There is a way to install CVS plugin without using eclipse marketplace. For security reasons I can´t access to it. Can I get the files and copy to a eclipse folder?
I am just learning java and still learning how best to organize code as well as deliver and implement it.  I am mocking up the many ways to run java.  

e.g. A bit simplified, but to describe what I have done: I have a project created in Eclipse with a single package that right now is only used for one thing, to download data from a third party.  In the future it will be doing more, e.g. uploading data to a third party, etc.

Would you recommend separating each application's specific classes to their own package in the project, e.g. an upload versus download and then common?

Would you recommend keeping all of the project's classes together and supplying a manifest main method that executes various class methods (e.g. upload versus download) based on a parameter?

It seems very simple to put everything into a single jar file, especially for our team who has to implement code on the servers.  Are there drawbacks to this?

Is it possible to execute a method other than the main method of a runnable jar file?  I am having problems with this way using the -cp command, with the actual jar file in the path.  The jar with the methods contains all of the necessary libraries.  What should the path look like?  Maybe that is what I'm getting wrong.

Thank you in advance for advice.
