Using external libraries in desktop programs

Hi everybody, i'm a bit newbie and i have some questions for you. Can I create a project in C# (VS2013) and use the exe as a desktop program? (I mean, if it's consider a desktop application). My main question is: Can i import external libraries on this
project? I don't know this, because it's hard to know if the users have the library (or is it include in the program?)
Thanks in advance :)

You can write windows forms or wpf applications ( and some other types ) using visual studio.
These are desktop applications which you can distribute.
A library is a dll.
Dynamic link library.
To use one you add a reference to it in your solution.
That dll is then a dependency for your application.
You can later build an msi which someone would use to install that application or you can deliver by clickonce.
http://msdn.microsoft.com/en-us/library/ms173084(v=vs.90).aspx
You do that using an install project which will detect those dependencies and include them in the msi you give to people to install your application.
There are a number of options:
Installshield lite
Wix
Setup and deployment project

Using external libraries in Web Dynpro DCs

Hi,
I've followed the example in the following blog for using external libraries in my Web Dynpro (WD) DCs:
/people/valery.silaev/blog/2005/09/14/a-bit-of-impractical-scripting-for-web-dynpro and some other messages in the forums. However, it isn't working exactly as described in the blog. I have to twist it a bit to get it work. I were wondering if anyone has any better solution for this problem?
The senario is like this:
- External libraries: a.jar, b.jar
- WD DCs: wd1, wd2 in that wd1 and wd2 are both using external libraries a.jar and b.jar; wd1 is a library DC that can be reused in wd2.
According to the example in the blog, the following steps are carried out:
- Step 1. Create an external library DC, add a.jar and b.jar to public part "ExternalLibs" as described in the blog.
- Step 2: Create, build, deploy J2EE Server / Library DC. (Add reference to the public part of the external library DC as a used DC, with both Build-time and Run-time dependency).
- Step 3: Create WD DC wd1, add used DCs and WD reference libraries as described in the blog. Add WD components as public part. Build and deploy WD DC wd1.
All are ok so far!
- Step 4: Create WD DC wd2, add used DCs and WD reference libraries as before. Try to build and FAIL!
The error occurs here because wd2 cannot access to the classes in the external libraries, similar to the problems described in thread Re: Problems with deploying a JAR file.
I've found a workaround, although quite tedious and cumbersom, but it works. My solution so far is:
- Round 1: Perform those 4 steps above, but in step 1, after adding the jars to the public part "ExternalLibs", set the property of the public part "purpose" to "compilation", then build and deploy all other DCs accordingly.
- Round 2: Change the public part "ExternalLibs" property to "assembly", then bulid and deploy all other DCs again.
And now I can reuse the external libraries in my WD DCs as well as WD DCs as library in other WD DCs.
I know it's not an elegant solution. So I were wondering if the experts out there can help me with better solutions?
Many thanks in advance for your help.

Van

Use external libraries in web dynpro java

Dear Experts,
I need to add an external library to my project.
Anyway, I do not know how to do it because it gives me many problems.
I tried modifying the classpath and placing it in the lib folder of the project from "Navigator".
Also project properties, add. jar outside, and throws me the following error:
[javac] Compiling 213 source files to D:\WORK\WORKSPACE\7.2.jdi\LocalDevelopment\t\2BF09F48E6D0E2C201262098A0E4D79F\classes
     [javac] ERROR: D:\WORK\WORKSPACE\7.2.jdi\LocalDevelopment\t\2BF09F48E6D0E2C201262098A0E4D79F\gen_wdp\packages\elsys\com\.....\wd\comp\....\MainView.java:34: package com.estaf does not exist
     [javac] ERROR: import com.estaf.jpay;
     [javac] ERROR:
Given these errors, I know my includes without problems and I can instantiate objects from library classes, but these errors I can not deploy.
I read the following link:
/people/raphael.vogel/blog/2008/05/05/how-to-use-external-libraries-in-the-sap-component-model-part-ii
I did everything the tutorial. I created the external library. I can see in my project "DC-Definition -> Used DCs" The public parts assembly and compilation. Now the problem is that it still does not recognize the classes of the libraries you want to use.
A level of code, when I try to instantiate the class does not recognize me. What could be missing? I did a couple of times step by step and gives me the same results.
I use SAP NetWeaver Developer Studio SAP NetWeaver 7.2 SP03 PAT0007 version.
Infinitely appreciate any help. Thank you very much.

please find below path for adding External Jar files.
right click on the webdynpro dc and select the properties .
then clcik on Java Build path->select libraries->select External External Jars.
after that just rebuild your project (not Build).

Using external libraries with Developer Studio 7.1 Composition Environment

Hi,
I downloaded DS 7.1 CE and tried to develop a simple application which uses an external library.
I created a development component for "external library" for the local development -> MyComponent, giving it the name "test2" (for the domain basis).
I imported the external library file using Import -> File System , then selecting the .jar file.
In the component properties browser I added a public part naming it "mylib2" setting the purpose to "ASSEMBLY" (my intention was that the libarry will be transferred during the deployment to the application server).
I right clicked on the public part to "managed entities". I selected the archive tree and checked the library file shown there (the one I imported before). #
Then I opended component properties of my web dynpro project and clicked on "Dependencies". The I chose "Add..." and selected the "test2" development component I created before (see above).
Then I tried to deploy the project (which uses this external library) using "Deploy Archive and Run"
After deployment the browser window opens and shows the ClassNotFoundException
So what did I oversee or do wrong?
BTW: Is it necessary for using external libraries to use a full fletched NWDI? Or can I use external libs also with netweaver development environments freely available for download on sdn.sap.com?
Any hints?
Thanks a lot
Hannes

Hannes,
If you want to use external libraries with DCs then you should follow the NWDI completely.
Check this step, otheways of using external libraries is mentioned <a href="http://help.sap.com/saphelp_nw70/helpdata/en/e3/de813e77d46245e10000000a114084/frameset.htm">here.</a>

Using external libraries in eSWT on 7.1

Hi again.
Is it still possible to use external libraries when developing applications for Handhelds on Mobile 7.1 (eSWT)? Or do we have any restrictions here?
Thanks,

Hi,
as long as your have POJOs it should be ok to use them still.

Using external libraries in DS 5.2 plugins

Hello,
I'm writing a moderately complicated preoperation plugin for Directory Server 5.2, and I've linked in glib 2.0 so I can use some of its data structures. Aside from some memory leaks I'm tracking down, things look okay, and the plugin behaves as expected.
Are there any reasons why I should avoid using external libraries in the directory server? I know that SLAPI has its own memory management code that glib isn't using, but I don't think that's the reason I have the leaks.
Thanks!
-lars

Plug-in library code runs inside the memory space of the server process, so it can be nice to have the memory management from the API.
Also if you have things coming in from all over the place, maybe there's a higher security risk, since there are more places where somebody could replace a dynamic library and do bad things when you load that code.
I don't recall us putting anything in the docs that said you should make a special effort to avoid doing linking out to external libraries. (If it's there, I don't see it with a quick google search.)

How to use external libraries jar files in the composite application?

Hi,
I have some external jars files (which consists of java classes) that I would like to use in my composite application.
I have created a DC with type as external library for the jars. However, I don't know how to specify the DC to be used in my caf application.
Can anyone help?
Thanks.
Regards,
Fui Voon

Hi,
My jar files consists only java classes and a manifest.mf. The files are compiled using jdk 1.4.2-b28. Will this be any issue?
It seems that if I ignore the error and continue step 7 which is to do deployment of the ear, the error given is
Cannot update it.
Caused by: com.sap.engine.library.bytecode.cf.CFException: Invalid constant pool tag, 60 at index 41.
Does anyone know what that mean?
Is there any sample that teach how to deploy external libraries as bundled library?
Thanks.

How to use external libraries and JAR files with OpenScript

Hello.
I am trying to include ApachePOI, JODATime, and Javamail in my scripts to handle different aspects of our automated performance tests.
I followed the documentation for Eclipse to be allowed to utilize these external libraries, however, when I attempt to run my tests the classes and methods that are being imported, show up with errors saying that they do not exist.
I think perhaps that I am using them incorrectly. I cannot see them as script assets, package assets, or project assets using the properties for these items. An error pops up and says those screens are not displaying correctly or display incorrect information.
If anyone can provide guidance on using these items, that would be great. Right now I'm trying to include them as "previously exported scripts" but I'm not sure that method will work.
Any advice is appreciated.
Thanks.
--tiff

Hi Tiff
For OpenScript 9.* there is an out of the box solution for that, all you need to do in OpenScript go to:
Script -> Script Properties -> Script Assets -> Add -> jar File ....
And that is it.

Using external libraries

Hello there,
I am finding solution for my software's proposal. I will have got some flex libraries in my project(air application), but I would like to dynamically switch off some libraries. For example, one version of application(for example the free version) will not have got all functions, so I would like to deny some libraries(the best solutions is, that libraries will not be a part of application, so anybody could not crack it). And when i will use the library in application, which is deny, no error occur(for example some conditions, if libraires is here, i will can use it, or not).
Which technology is the best solution?
Thank you very much and sorry for my english

An AIR application can load external code using the Loader.loadBytes API. But that would mean you download pieces of the application on startup based on licensing details. That might not be optimal and it only adds a level of protection. In the end, if people are bent on breaking your software they could potentially get around this as well.

Using external drive to run programs

I have just bought a 500Gb External Hard Drive for my MBP, which can be connected via USB, FW400 or FW800.
I was wondering if i were to install applications, games such as "Call Of Duty 2" or a program such as "Pro Tools" onto the external drive, would i be able to run them on my MBP from there, and if so, will it run slower than it would if it were installed on the internal HD?
Any help/advise would be great. Thanks

That other guy is right that it won't run any slower. I don't know about CoD2, but I've been meaning to try running it from an external HD.
As for Pro-Tools, you would be correct to run it from the external drive for two reasons:
a) the ability to take your session to a different pro-tools rig (duh)
b) Pro Tools, depending on your computer's particular specifications, will either barely run or not run at all from a record drive (in this case, your external 7200rpm drive) under 7200rpm. To be honest, I would highly recommend upgrading to a 10,000-15,000 rpm drive. 7200 will work, but you might have problems when recording 24-bit audio (don't use 16-bit, its garbage). As long as the rest of your comp is up to par, you shouldn't have any real problems though.
email me if you have any other pro-tools or CoD2 (mac version) questions. I'm currently in the process of getting my Pro-Tools Operator's Certification, so I could use the practise:)

Using external libraries with Actionscript Project

Hi,
I've hit a bit of a brick wall trying to do something that I figured would be a relatively simple task. I'm working on multiple projects and I'm trying to build a number of SWC libraries shared between a number of Actionscript projects using Flash Builder 4. The projects using the SWC's build just fine, but yield this error when run:
VerifyError: Error #1014: Class <whatever> could not be found.
Here's a simple example:
1) Create a new library project.
2) Add a new Actionscript file in the "testpackage" package.
3) Slap this code into that file:
package testpackage
    public class stuff
        public function Testing():void
            trace("Oh yeah!");
4) Create a new Actionscript Project named Launcher
5) In "Properties->Actionscript Build Path", hit "Add SWC Folder" and browse to wherever the library project gets built to.
6) In the AS file that's generated, add code something like:
package
    import flash.display.Sprite;
    import testpackage.*;
    public class Launcher extends Sprite
        public function Launcher()
            var s:stuff = new stuff();
            s.Testing();
7) Run this bad boy.
I get the above error and I have no idea why. Everything builds fine so I'm not sure what I'm doing wrong. I read somewhere that you can manually extract the .swf file from the generated .swc and load that explicitely in code. This is a pretty horrible workflow and I hope it's not the answer
Thanks a ton in advance!
-D

Check linkage type in Build Path for project Launcher when you add Swc folder. It has to be merged into code.
If it is external, you'll see this error.
That aside, why not do "add project" instead of "add swc folder"?

How to use external jar in a program

I am writing a java program which requires The class org.apache.commons.lang.StringUtils and the method StringUtils.upperCase(). I have downloaded the commons-lang-2.1.jar jar and put it in the lib directory under my project directory.
But while compiling the program I am getting an error like this :
package org.apache.commons.lang does not exist
and can not find symbol , symbol : variable StringUtils
Could anyone suggest me what to do so that the program compiles without error?

I am using command line javac tool.
Could you tell me how to tell compiler to include the
jar.javac -classpath /some/directory/commons-lang-2.1.jar;(other required paths and/or jars) files to compile go here
Please read tutorials too.
http://java.sun.com/docs/books/tutorial/
I would also suggest a good build tool called Ant.

Use external libraries in XS Engine

I'm trying to use third party Javascript libraries for my projects in the XS Engine. Let's assume I'm writing a script that has two direct dependencies:
my-app.js
|-- dependency-a.js
|-- dependency-b.js
        |-- subdependency-b1.js
        |-- subdependency-b2.js
How can I make dependency-a.js and dependency-b.js (including their dependencies) available for my-app.js in the XS Engine?
Does the XS Engine support some kind of package management / module system (like CommonJS)?
Currently the only method I found for one Javascript file to depend on another is to make the dependency an *.xsjslib file and import it. This isn't a feasible solution in my scenario, because:
1. Pretty much all server-side libraries I want to use are modules based on CommonJS (mainly written for Node.js), and would have to be adapted
2. Not all libraries I use have been validated by JSLint, so HANA doesn't actually allow me to activate them till they are (is there a way to disable JSLint?)

UPDATE:
The error I reported below was in my js code. Not sure where, but doesn't appear to be an "XS issue".
For others looking at this thread, below is a more detailed example for your reference.
STRUCTURE:
-Content
--MyPackage
---MyApp.xsjs
---MyLib.xsjslib
MyApp.xsjs code:
$.import("MyPackage","MyLib");
var x = $.MyPackage.MyLib.MyObject.MyFunction("my test string");
$.response.setBody(x);
MyLib.xsjslib code:
var MyObject:{
     MyFunction: function (myString) {
          return = "You passed in the string: " + myString;
ORIGINAL:
I'm getting the following error:
Found the following errors:
===========================
TypeError: "xml2json" is read-only (line 146 position 0 in /sales/xml2json.xsjslib)
here is my import code:

How to use external libraries in EP

Hi!
I am with dificulties in utilizing an external ".jar" file in a Portal application (JSPDynPage). The ".jar" file is the JSTL 1.0 version. It compiles and is exported correctly (SNDS to Portal), but give me an error at runtime (NullPointerException). There is any restrictions in utilizing external ".jar"s files, e.g., not especific/proprietary versions?
Regards,
Alex

hi,
You can place the external .jar files under dist/PORTAL-INF/lib . By placing the external jars it would certainly run
The other way is as follows
1. Go to navigation perspective
2. Get into the project\lib folder of the your project. copy the jar files into it
4. Right click on the project
5. Click on properties
6. Click on java build path
7. Go to libraries tab
8. click on Add Jars button
9. Select the jar in your project
11. Recompile
12. Deploy
Hope it helps..
