Access中，窗体最大化时，控件怎样跟着移动
阅读权限20
在线时间 小时
问题是这样的:
本人有一个窗体，需要在打开该窗体时加载一个宏，这个宏会使该窗体最大化，在未最大化时，标签等控件是在中间的位置的，但是窗体最大化以后，控件却并不会跟着窗体居中，而是全部控件停留在左上角，请问高手们，这样该怎么办？能否用宏解决？谢谢

Narya性能测试（二） / Error (-17998): Failed to get [param not passed in call] thread TLS entry.
/blog/869744
本来想用LoaderRunner对Narya的网络性能再做一次测试，LR的java vuser可以直接用java来编写测试脚本，本来还是挺方便的，但是不知道为什么脚本一跑起来就报这么个错：
Error (-17998): Failed to get [param not passed in call] thread TLS entry.
实在是有点郁闷的，网上搜索了很久也没找到个所以然，只是有人模模糊糊的指出，有可能是LR的java vuser脚本不支持多线程。想来也是，LR是靠license的并发数来卖钱的，如果你一个vuser可以开多个线程，每个vuser开100个线程，那一个100人的license就可以当1万人来用了，但我们narya的一个client本身就要开几个线程，看来是无法用LR来测了。
好在开源的社区里还有一个叫JMeter的性能测试工具。我们希望通过工具能够更灵活的来配置我们的测试用例，包括并发用户数，每个用户发送的请求数，和每个请求之间的间隔时间等。JMeter内置了一种叫做java sampler的sampler，我们需要继承AbstractJavaSamplerClient这个类，实现它的下面这个方法。

Loadrunner8.1 + JDK1.5如何解决System Exceptions: EXCEPTION_ACCESS_VIOLATION
/?uid-114582-action-viewspace-itemid-234320
Vuser协议的遇到Exception was raised when calling abort-cleanup function in extension java_int.dll: System Exceptions: EXCEPTION_ACCESS_VIOLATION问题，现讲解下这个问题的解决方法。
首先，保证纯净的
我 之前装的是Loadrunner9.5，准备配JDK1.6，最后怎么都是报错，然后采用Loadrunner8.1 + JDK1.5问题依旧，最后重装了系统，采用Loadrunner8.1 + JDK1.5问题解决。连网上说的A_lrunner_java_protocol_fixes_Feb_05.exe的补丁也未打。
/topics/download/7aa3-382e-a729-0e03cec0417e
/ddimg/uploadsoft//LR_java.zip
其次：确认JDK环境变量是否正确设置xp下配置JDK环境变量：
1.安装JDK，安装过程中可以自定义安装目录等信息，例如我们选择安装目录为D:\java\jdk1.5.0_08；　 2.安装完成后，右击“我的电脑”，点击“属性”；
3.选择“高级”选项卡，点击“环境变量”；
4.在“系统变量”中，设置3项属性，JAVA_HOME,PATH,CLASSPATH(大小写无所谓),若已存在则点击“编辑”，不存在则点击“新建”；
5.JAVA_HOME指明JDK安装路径，就是刚才安装时所选择的路径D:\java\jdk1.5.0_08，此路径下包括lib，bin，jre等文件夹（此变量最好设置，因为以后运行tomcat，eclipse等都需要依*此变量）；
Path使得系统可以在任何路径下识别java命令，设为：%JAVA_HOME%\%JAVA_HOME%\jre\bin　
CLASSPATH为java加载类(class or lib)路径，只有类在classpath中，java命令才能识别，设为：.;%JAVA_HOME%\lib\dt.%JAVA_HOME%\lib\tools.jar (要加.表示当前路径)　　%JAVA_HOME%就是引用前面指定的JAVA_HOME；
6.“开始”－&;“运行”，键入“cmd”；
7.键入命令“java -version”，“java”，“javac”几个命令，出现画面，说明环境变量配置成功；
8. DOS中查看相关环境变量是否正常显示echo %path%，echo %classpath%，echo %java_home%。
再则，相关的Class有没有Import进去。
保证上面三步，就可以解决System Exceptions: CEPTION_ACCESS_VIOLATION报错问题。
[原创]如何解决LodRunner中报错关于Error -10489 : Exception was raised when calling per-thread-terminate function
/mayingbao/archive//410708.html
[原创]如何解决LodRunner中报错关于Error -10489 : Exception was raised when calling per-thread-terminate function 　　在用Loadrunner实施性能测试时，采用Goal模式加压，存在如果持续长时加压时ＬoadRunner的Controller会报 Error -10489 : Exception was raised when calling per-thread-terminate function错误；　　问题产生原因：
Unlike the earlier Windows versions, Windows 2000 and Windows XP have the default environment set to C:\Document and Settings\&user-name&\Local Settings\Temp instead of C:\Windows\temp. This long path with a space can cause several problems for LoadRunner. To resolve the issue, change to a directory without empty spaces. 　 解决方法：
在C盘（或是其它盘均可以）新建TEMP文件夹(为了后续设置临时文件准备)
右键＂我的电脑＂-&高级-&环境变量-&编辑修改TEMP变量目录，指身上面新建的目录，如我的指向C:\TEMP-&保存即可^_^
SAP ATP 应用服务负载均衡 192.168.40.224 test
/thread-913-1-1.html
/%BD%A3%CA%A5_%B7%A8%CA%A6/blog/item/d8b5c23ac763fe.html
共两步，一是服务器的设置，二是客户端登陆设置。先在SAP中使用SMLG 进行服务器分组。实例名是SAP系统中定义过的，你没法删也没改。。我们先建一个Group，然后给Group命名为X，把实例加到组中。服务器的配置就这么简单。下面在用户端设置SAP message服务器,为下一步作准备。填入以上信息，如果出现1处的错误信息，那么需要执行以下步骤设定Service端口映射：SAP登陆时会从Windows的service文件中获取服务名称，需要在这个文件中指定service名称与端口映射，在%systemroot%\system32\drivers\etc\中打开文件services并在其最后加入一行：sapmsCID
SID是SAP系统的SID(系统ID)号码，需要被替换为你自己的，在SID与3600中的间隔推荐用Tab键而不是使用空格分隔，如果讯息服务器填的是主机名，并且没有DNS来解析，那么还需要在上面指定的目录中的hosts文件中加入IP到主机名的映射注意：从理论上讲(自已想像的)，SAPGUI总是连接到SAP message服务器，message服务器则判断当前各服务器的响应时间，哪台响应时间最短，则让GUI连到哪台。如果你发现你的服务器配配置都差不 多，但GUI很多都连在一台服务器上，那说明另一台响应时间有点问题需要调整了。你随时可以通过AL08查看各服务器的登陆情况，也可以通过SMLG按 F5查看各服务器的响应时间。可能遇到的问题1、在给用户配置客户端登陆时，系统标识中输入PRD，但无法解析出IP。解决：未配置消息服务器，请更改sapmsg.ini文件。2、系统标识中输入PRD后，无法选择组服务器，出现一个错误提示，还是乱码的原因没找到，估计是service文件中某些通讯端口设置有问题，造成无法与message服务器通信，当然也就没法选择组服务器了。解决：从其他正常的机器上找到windows安装目录下的system32\drivers\etc下的service文件，拷一个过来覆盖就好。
JCO连接怪现象
/problems/3667
这两天用JCO做个接口从数据库导数据进R/3
昨天调好得程序今天来调试结果报如下异常，JCO连接也不起作用了
Exception in thread "DefaultQuartzScheduler_Worker-4" java.lang.ExceptionInInitializerError: JCO.classInitialize(): Could not load middleware layer 'com.sap.mw.jco.rfc.MiddlewareRFC'
JCO.nativeInit(): Could not initialize dynamic link library sapjcorfc [no sapjcorfc in java.library.path]. java.library.path [C:\Program Files\Java\jdk1.5.0_06\C:\Tomcat 5.5\bin]
貌似是说librfc32.dll sapjcorfc.dll两个动态库得问题。
开始我没注意，我采用在类里面嵌入web测试，发现我得SAP配置是正确得，也能正常插入数据，为什么在web容器里面就跑不起来，应说我的两个库文件不在还是怎么着。
无奈之下只有将这两个库文件外加sapjco.jar一起粘贴进
C:\Program Files\Java\jdk1.5.0_06\bin
C:\Tomcat 5.5\bin
结果程序跑起来了…………
Call BAPI with SAP Enterprise Connector Guide
/blog/412107
This document is step by step guide on how to calling BAPI in Java with SAP Enterprise connector.
SAP BAPI is remote enabled function module, and we can call it with JCO library.
SAP Enterprise Connector is a wizard to generate proxy code for calling remote function module.
1.Install NWDS
First download NWDS from SDN, SAP NetWeaver Composition Environment 7.1 SR5 - Trial Version
You should register an account in SDN first.
Extract downloaded files to temp folder. Then install NWDS follow the installation instruction..
2.Create Java Project
Start Netweaver Development Studio, create Java project.
Add related library to build path:
3.Create proxy class with SAP Enterprise Connector
Select the function module , and click Finish button, Waiting for NWDS will generate proxy codes.
4.Test generated proxy class
JCO.Client jcoClient =
JCO.createClient(
"CP.WANG",
"justin65",
"/H//H/sapecc",
jcoClient.setProperty("jco.client.codepage", "4110");
CompanyCode_PortType proxy = new CompanyCode_PortType();
proxy.messageSpecifier.setJcoClient(jcoClient);
jcoClient.connect();
Bapi_Companycode_Getlist_Input input = new Bapi_Companycode_Getlist_Input();
Bapi_Companycode_Getlist_Output output = proxy.bapi_Companycode_Getlist(input);
Bapi0002_1Type[] codes = output.getCompanycode_List();
if(codes!=null && codes.length& 0){
int len = codes.
for(int i=0;i&i++){
System.out.printf("%-10s", codes[i].getComp_Code());
System.out.print(new String(new String(codes[i].getComp_Name()).getBytes("UTF-8"),"GBK"));
System.out.println();
} catch (ApplicationFaultException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SystemFaultException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
jcoClient.disconnect();

从一个脚本谈loadrunner的脚本初始化
http://www.blogjava.net/qileilove/archive//410079.html
昨天一个同事请我一个问题，在下列代码中如何将 InputStream is 这个元素只初始化一次呢？
* LoadRunner Java script. (Build: _build_number_)
* Script Description:
import lrapi.
import java.io.F
import java.io.FileInputS
import java.io.InputS
import mon.io.ByteS
import com.jd.jfs.JingdongFileS
public class Actions
File file = new File("C:/8K.file");
InputStream is = // 返回一个byte数组&pre code_snippet_id="145362" snippet_file_name="blog__8044261" name="code" class="java"&
byte[] fileBytes = new byte[(int) file.length()];
// 创建一个数据来保存文件数据
JingdongFileSystem jfs =new JingdongFileSystem();
public int init() throws Throwable {
is = new FileInputStream(file);
ByteStreams.readFully(is, fileBytes);
is.close();
//jfs = new JingdongFileSystem();
} //end of init
public int action() throws Throwable {
lr.start_transaction("jfs-w");
String key = jfs.writeBytes(fileBytes);
System.out.println(key);
} catch (Exception e) {
e.printStackTrace();
lr.end_transaction("jfs-w", lr.AUTO);
}//end of action
public int end() throws Throwable {
}//end of end
我们知道，在loadrunner的java_vuser协议的脚本中，init方法在每个vuer初始化的时候都会被执行一次，换句话说N个用户就会被执行N次，所以上面的脚本中inputStream对象会被初始化N次。我随即做了如下修改
File file = new File("C:/8K.file");
static InputStream is =
// 返回一个byte数组　　&span style="color: #ff0000; "&
&/span&　　　　byte[] fileBytes = new byte[(int) file.length()];
// 创建一个数据来保存文件数据
JingdongFileSystem jfs =new JingdongFileSystem();
public int init() throws Throwable {
if(is==null){
is = new FileInputStream(file);
ByteStreams.readFully(is, fileBytes);
is.close();
//jfs = new JingdongFileSystem();
}//end of init
理论上来说，上述代码实现了单例模式。但是这个脚本并发下无效。。。 经过和开发探讨最终换了以下的代码来处理：
File file = new File("C:/8K.file");
fileBytes = new byte[(int) file.length()];
// 创建一个数据来保存文件数据
InputStream is = new FileInputStream(file);
ByteStreams.readFully(is, fileBytes);
is.close();
} catch (Exception e) {
e.printStackTrace();
jfs = new JingdongFileSystem();
静态初始化块:使用static定义,当类装载到系统时执行一次.若在静态初始化块中想初始化变量,那仅能初始化类变量,即static修饰的数据成员. 总结一下： 在java_vuser协议的脚本中: 1. vuser_init模块始终不会被执行； 2. init方法会被初始化合并发数相同的次数 3. 如果想实现多个并发用户公用一个变量，请使用静态初始化块。
