在PB中如何选择目录？

PB 操作手册创建连接1．正常安装即可2．打开PB，点击database按钮3．在左侧选择ODB ODBC，右单击，选择New profile,弹出如下对话框4. 在profile name输入要创建的库名5. 在data source下选择要连接的ODBC连接6. 在user ID和password分别输入要连接的数据库的用户名和密码7. 在Driver-Specific parameters中输入驱动的路径，如下图8．创建ODBC连接，控制面板-管理工具-数据源-添加9．根据数据库，选择匹配的驱动程序，如连接SQL2005，请选择SQL Server，点击完成10. 选择数据库的服务器，点击下一步，选择“使用用户输入登录ID和密码的SQL Server 验证”；勾选”连接SQL Server以获得其他配置选项的默认设置”；分别输入连接数据库的用户名和密码点击下一步、下一步点击测试数据源，如果测试成功，则表明连接成功11. 在Database profile setup-ODBC框内，选择“preview”，点击test connection,如果提示连接成功，则可以对库进行操作对库进行操作1.选择一个已创建的库，右单击，选择connect2.选择一张表，右单击，选择edit data-grid，即可查看数据3.选择一条数据，右单击，选择delete/insert row，可以进行删除/添加数据，修改后需要保存4.选择ISQL session，可以编写、执行SQL5.选择一条数据，右单击，选择save row as，可以将所选数据存为指定格式的数据，如CSV,TXT等6.选择一张表，使其处于grid状态，在菜单栏，选择rows-import,可以选择数据源，将数据导入表内，导入后需要保存。

PB使用小技巧1. 如何使PB窗口总在最上层通过SetWindowPos函数把窗口的显示层次修改为HWND_TOPMOST，就可以使指定窗口永远不会被其他窗口覆盖，该函数声明为：Function Long SetWindowPos(Long hwnd, Long ord, Long x, Long y, Long dx, Long dy, Long uflag) Library “user32.dll”参数1为要顶层显示的窗口句柄，参数2指定显示的层次，参数7为附加选项，其余参数指定窗口位置和大小，均可忽略。

在窗口的Open或Activate事件中加入如下函数调用：SetWindowPos(Handle(This),-1,0,0,0,0,3)参数2取-1表示在最顶层显示窗口，取1表示在最底层显示；最后一个参数若取1，表示窗口大小保持不变，取2表示保持位置不变，因此，取3（=1+2）表示大小和位置均保持不变，取0表示将窗口的大小和位置改变为指定值。

2. 在PB中如何获得光盘盘符通过GetDriveType函数可以获取驱动器（如：软驱、硬盘、光驱、网络映射驱动器等）的信息，该函数声明为：Function Unit GetDriveTypeA(String drive) Library “kernel32.dll”参数为一个盘符（如“C:”），返回值：1表示未知，2表示软驱，3表示本地硬盘，4表示网络驱动器，5表示光驱。

因此如下代码可以获得光盘的盘符：For I=Asc(‘D’) to Asc(‘Z’)//列举所有可能的CDROM的驱动器If GetDriveTypeA(Char(i)+”:”) = 5 Then//若找到CDROMMessagebox(“CDROM”,Char(i)+”:”)//显示光盘盘符Exit //退出循环End ifNext3. 在PB中如何获取目录信息（1）获取当前目录。

通过GetCurrentDirectory函数可以获取当前目录，该函数声明为：Function Ulong GetCurrentDirectory(Ulong buflen,ref String dir)Library “kernel32.dll”参数2为接受当前目录的字符缓冲区，前面必须加ref表示地址引用；参数1用来指定字符缓冲区的长度。

pb dirlist 函数-回复pb dirlist 函数是一个用于列出目录下文件和子目录的函数。

具体来说，pb dirlist 函数接受一个参数，即目录的路径，然后返回一个包含目录下所有文件和子目录的列表。

在本文中，我们将详细介绍pb dirlist 函数的实现步骤并提供示例代码。

1. 引言首先，我们来解释一下为什么需要pb dirlist 函数。

在许多编程任务中，我们经常会遇到需要列出特定目录下文件和子目录的需要。

例如，在构建一个文件管理器或者需要读取特定文件夹下所有文件的任务中，pb dirlist 函数可以提供快速、方便的解决方案。

2. 实现步骤以下是pb dirlist 函数的实现步骤：2.1 根据输入的目录路径创建一个空的列表，用于存储文件和子目录的名称。

2.2 使用操作系统相关的API，如os 模块，在给定的目录下获取所有文件和子目录的名称。

2.3 遍历获取到的所有文件和子目录的名称。

2.4 判断该名称是一个文件还是一个子目录。

2.5 如果是一个子目录，则递归调用pb dirlist 函数以获取子目录下的文件和子目录的名称，并将结果添加到列表中。

2.6 如果是一个文件，则将文件的名称添加到列表中。

2.7 返回包含所有文件和子目录名称的列表。

3. 示例代码以下是一个使用Python 语言实现的示例代码：pythonimport osdef pb_dirlist(directory):dir_list = []for item in os.listdir(directory):item_path = os.path.join(directory, item)if os.path.isdir(item_path):dir_list += pb_dirlist(item_path)else:dir_list.append(item)return dir_list# 在此处替换为实际的目录路径directory_path = "/path/to/directory"result = pb_dirlist(directory_path)print(result)4. 总结在本文中，我们介绍了pb dirlist 函数的实现步骤并提供了示例代码。

PB中下拉列表使用的若干技巧于红聂尚宇摘要对PB中下拉列表的使用方法进行了研究，并提出了几种使用下拉列表的实现方法,实践表明这些方法具有简单实用的特点。

关键词下拉列表；动态；控件；事件；Some Skills in the Use of DDLB of PBYu Hong Nie ShangyuDepartment of Electronic Engineering, DFUAbstract The use of DDLB in PB is studied and some skills are proposed. The results show that these skills are simple and practical.Key words DDLB; dynamic; control; event随着科学技术的不断发展,计算机已经应用于社会的各个领域，相应的管理软件的编制工作显得尤为重要。

现有的编程工具中，PowerBuilder 是数据库管理软件设计比较理想的工具，但如何合理地选用控件和灵活地使用每一个控件，以充分发挥PB的优势，是人们在编程过程中常遇到的难题。

作者对PB中的控件之一——下拉列表的使用[1]进行了研究，并提出几个灵活使用下拉列表的方法。

1 下拉列表及其相应的事件①下拉列表是在窗口中定义的一个控件，与之相应的事件如下表所示：件，还会触发Modified事件。

2 动态使用下拉列表传统的下拉列表使用是静态的,它在一定程度上满足了编程的需要,但是不能满足所有需要。

例如，有时希望下拉列表中的选项在程序运行过程中可以变化,这用静态下拉列表定义选项是不能实现的,这就促使人们去思考如何使用动态下拉列表。

有两种情况需要使用动态下拉列表。

1）下拉列表中的选项与数据库中某列的内容相关联②实际应用中，在对数据库表中的数据按名称进行查询时，为了减少输入量，可以将库中某列的内容（如单位名称）列在下拉列表中供用户选择，这样既可以保证选中的项目一定是库中的项目，而且不用输入汉字；又使下拉列表的使用具有一定的灵活性，动态下拉列表选项的确定必须在下拉列表被使用之前进行，可以在下拉列表所在窗口的Open事件中确定，也可以在下拉列表的Getfocus事件中确定，相应的script为string id,icint i-op=1declare c1 cursor forselect hotelid from hotelid-dangan using SQLCA;open c1;fetch c1 into: id;do while sqlca.sqlcode=0select p1602 into :ic from p16 where p1601=:id using sqlca;if finditem(ddlb-1,ic,1)=-1 thenddlb-1.insertitem(ic,+i-op)i-op=i-op+1end iffetch c1 into :id;loopclose c1;其中，下拉列表中的项目取自数据库表hotelid-dangan 的hotelid 列所对应的p16表中的p1602(即单位名称)。

树形目录在PB中的实现与应用1.引言在管理信息系统的开发中，经常需要获取本地计算机中的树形目录结构和相应的文件信息，如进行目录的选择和特殊文件的选取，在PB中并没有提供专门的树形目录对象，这样就需要程序开发人员自己来实现相应的树形目录。

本文针对这种情况，提供了一种用纯PB代码实现树形结构的方法。

2.PB中树形目录的实现方法PB中的ListBox列表框控件提供了显示目录和文件的能力。

在程序中可以利用PB的树形控件TreeView动态生成树形目录结构。

我们使用ListBox控件的函数DirList来实现，函数DirList以满足条件的文件名填充列表框的列表项，其使用方法如下：listboxname.DirList（文件模式，文件类型）其中文件类型的值如下所示：在程序中可将几种类型的值相加以获取相应的文件或目录信息。

下面结合一个实例介绍树形目录的实现方法。

通过树形目录可以获取计算机中的任意目录，然后显示需要显示的文件（本例中显示浏览器可以查看的文件类型：htm,html,swf,gif,jpg,txt等）。

程序中主要使用的控件如下所示：程序具体实现分成以下几个步骤：第一步：在tv_dir的constructor事件中生成所有驱动器信息，代码如下：String ls_DriverTypelb_dir.DirList("",16384)li_count = lb_dir.totalitems()IF li_count > 0 thenfor i = 1 to li_countltvi_bel = lb_dir.Text(i)ltvi_New.Data = i -1ltvi_New.Children = TRUE//根据驱动器类型设置图标ls_DriverType=uf_drivetype(lb_dir.Text(i))//函数uf_drivetype用来获取驱动器类型，根据类型设置图标Choose case ls_DriverTypecase "REMOVABLE"ltvi_New.PictureIndex = 5ltvi_New.SelectedPictureIndex =5CASE "FIXED"ltvi_New.PictureIndex = 1ltvi_New.SelectedPictureIndex =2CASE "CDROM"ltvi_New.PictureIndex = 6ltvi_New.SelectedPictureIndex =6END CHOOSEThis.InsertItemlast(0, ltvi_New)nextThis.selectitem(1)End if第二步，在tv_dir的itempopulate事件中生成相应目录的下级目录信息：For li_i=1 to li_numls_Data=lb_dir.Text(li_i)If Mid(ls_data,1,1)="[" Thenltvi_bel =mid(ls_data,2,len(ls_data) -2 )ltvi_New.Data = 1LB_next.dirlist(ls_driver+":\"+ltvi_bel,16+32768)if lb_next.totalitems()>1 Thenltvi_New.Children = TRUEelseltvi_New.Children = FalseEnd ifltvi_New.PictureIndex = 3ltvi_New.SelectedPictureIndex =4tv_dir.InsertItemlast(handle, ltvi_New)End ifNextEnd IfIF li_level>=2 Then //选择目录树中的子目录ls_driver=uf_get_dir(li_level,tv_dir,handle,ltvi_bel)lb_dir.DirList(ls_Driver,16+32768) //显示当前目录子目录信息li_num=lb_Dir.totalitems()For li_i=1 to li_numls_Data=lb_dir.Text(li_i)If Mid(ls_data,1,1)="[" and mid(ls_data,2,2)<>".." Thenltvi_bel =mid(ls_data,2,len(ls_data) -2 )ltvi_New.Data = 1LB_next.dirlist(ls_driver+"\"+ltvi_bel,16+32768)if lb_next.totalitems()>1 Thenltvi_New.Children = TRUEelseltvi_New.Children = FalseEnd ifltvi_New.PictureIndex = 3ltvi_New.SelectedPictureIndex =4tv_dir.InsertItemlast(handle, ltvi_New)End ifNextEnd If第三步：当用户单击某一具体目录时，显示该目录中满足条件的文件名，代码如下：Int li_num,li_i,li_long,iTreeViewItem ltvi_curString ls_dir,ls_dataString Filetype[8]//设定需要显示的文件类型filetype[1]=".htm"filetype[2]=".html"filetype[4]=".swf"filetype[5]=".gif"filetype[6]=".jpg"filetype[7]=".shtml"filetype[8]=".txt"li_long=8this.GetItem(handle,ltvi_cur)If ltvi_cur.level=1 thenls_dir=mid(ltvi_bel,3,1)+":\"elsels_dir=uf_get_dir(ltvi_cur.level,this,handle,ltvi_bel)end ifis_dir=ls_dirLb_next.DirList(ls_dir+"\*.*",0+1+2+4+32) //显示所有文件li_num=lb_Dir.totalitems()lb_file.Reset()//将指定文件显示在列表框中For li_i=1 to li_numls_Data=lb_next.Text(li_i)For i=1 to li_longif match(lower(Right(ls_data,len(FileType[i]))),Filetype[i]) then lb_file.addItem(ls_data)NextNext第四步：在OLE控件中显示所选文件的内容，主要代码如下：其中程序中使用的uf_get_dir为用户自定义函数，该函数用来获取所选定目录的完整路径。

pb dirlist 函数-回复[pb dirlist 函数] 一个强大的目录列表函数目录列表是一个常见的需求，尤其是在处理文件系统或网站开发中。

为了方便地获取和展示目录中的文件和子目录，开发者通常需要编写大量的代码。

然而，幸运的是，有一个强大的函数[pb dirlist]可以轻松地完成这项任务。

[pb dirlist]是一种现代化的函数，广泛应用于不同的编程语言和平台上。

它可以给定一个路径作为参数，并返回一个包含该路径下所有文件和子目录的列表。

这个函数提供了丰富的选项，以满足各种需求，并能够灵活地适应不同的应用场景。

使用[pb dirlist]只需要几个简单的步骤。

首先，我们需要确定要读取的目录路径。

可以是本地文件系统中的任何目录，也可以是远程服务器上的目录。

接下来，我们需要选择适当的选项来配置[pb dirlist]函数的行为。

选项包括排序方式、过滤规则、文件大小限制、递归深度等。

例如，我们可以选择按文件名称进行排序，这样可以更容易地找到目标文件。

另外，我们还可以添加一些过滤规则，比如只显示特定文件类型或名称匹配的文件。

一旦我们确定了选项，我们就可以调用[pb dirlist]函数，并将路径和选项作为参数传递进去。

函数将会执行相应的操作，并返回一个包含文件和子目录的列表。

这个列表可以是一个数组、一个数据框架或一个迭代器，具体取决于使用的编程语言和平台。

在得到目录列表后，我们可以进一步处理数据。

我们可以根据需要进行排序、过滤、转换或分组。

这样，我们就可以根据自己的需求，将目录列表展示在不同的环境中。

与传统的目录列表函数相比，[pb dirlist]具有许多优势。

首先，它是一个高度可定制的函数，可以根据实际情况灵活选择选项，以满足我们的需求。

其次，它是一个高效的函数，可以快速获取大量的文件和子目录，并进行相应的处理。

最后，它是一个跨平台的函数，可以在不同的操作系统和编程语言中使用，无需额外的配置。
