水晶参数 [英] Crystal parameters

问题描述

你好NG，


经过一段时间的等待，我的书店，马萨诸塞州沃尔瑟姆的SoftPro进入了Brian

Bischof的书：Crystal Reports .NET编程。我已经阅读了几本关于

CR的书，但我对它很新，C＃和SQL。这本书非常好。

无所畏惧，我已经将我旧的COBOL ERP系统转换成C＃的
MCS-3。我有相当多的库存控制已完成并正在工作。

对于报告我试图使用CR。我有六个人直接从SQL Server数据库工作

。为了做记录（好的，我是一个旧的COBOL手！阅读行。）选择我在数据库中有一个名为

im_planner_code的字段（OK，列） 。使用默认参数？plannerCode I

能够选择im_planner_code =" A"的所有行。我想

开发我自己的参数对话框。首先，我在Form1303的load事件中调用了下面列出的代码

。它编译干净，但在突出显示的行处有一个

执行错误。我当然想知道

我的问题是什么，但除此之外我还需要知道如何调试CR执行

错误。


.NET下的CR是否有好的新闻组？我目前阅读：

Microsoft.public.dotnet.languages.csharp。提前谢谢。


干杯，


鲍勃

Hello NG,

After a bit of a wait my bookstore, SoftPro of Waltham, MA, got in the Brian
Bischof book: Crystal Reports .NET Programming. I have read a few books on
CR, but I am very new to it, C#, and SQL. The book is excellent.
Undaunted, I have plowed into a conversion of my old COBOL ERP system,
MCS-3, into C#. I have quite a bit of Inventory Control done and working.
For reports I am trying to use CR. I have a half a dozen of them working
directly off of the SQL Server database. In order to do record (OK, I am an
old COBOL hand! Read row.) selection I have a field (OK, column) called
im_planner_code in the database. Using the default parameter ?plannerCode I
am able to select all rows with im_planner_code = "A". I would like to
develop my own parameter dialog box. To start I have invoked the code
listed below at the load event of Form1303. It compiles clean, but has an
execution error at the highlighted line. I would of course like to know
what my problem is, but beyond that I need to know how to debug CR execution
errors.

Is there a good newsgroup for CR under .NET? I currently read:
Microsoft.public.dotnet.languages.csharp. Thank you in advance.

Cheers,

Bob

推荐答案

嗨NG，


我改变了方法并取得了进展。下面的代码现在使用

CrystalReportViewer类。它的工作原理除外：


1 /它显示默认参数屏幕，尽管我提供自己的参数是
。然后在正确运行我的参数.Value =" A"

之前，它会闪烁

标准参数屏幕的正确结果。 Load事件是参数

over-rides的正确位置吗？


2 /最终报告没有设置Zoom（75）属性但是还原为

100％。


TIA

Hi NG,

I changed my approach and made progress. The code below now uses the
CrystalReportViewer classes. It works except that:

1/ It displays the default parameter screen in spite of the fact that I am
providing my own parameters. It then flashes the correct result of the
standard parameter screen before running my parameter .Value = "A"
correctly. Is the Load event the correct placement for parameter
over-rides?

2/ The final report does not set the Zoom(75) property but reverts back to
100%.

嗨罗伯特，


首先，我想确认一下我对你的问题的理解。从

您的描述，我知道您有两个问题。第一个是

，参数屏幕出现问题。第二个是缩放

无法正常工作。如果有任何误解，请随时告诉我

。


我对Crystal Report不太熟悉。但根据您提供的代码，我建议您提供代码行

this.crystalReportViewer1.Zoom（75）;设置报告源后。 （尝试

将此行移动到Form_Load的底部。）因为设置报告

source可能会刷新视图，这会导致Zoom无法正常工作。


我不太清楚为什么会出现参数问题。如果你能在整个项目中给我发一个

repro，我会尝试调试它。谢谢！

Hi Robert,

First of all, I would like to confirm my understanding of your issue. From
your description, I understand that you have two questions. The first is
that there is something wrong with the parameter screen. The second is zoom
is not working properly. If there is any misunderstanding, please feel free
to let me know.

I''m not quite familiar with Crystal Report. But based on the code you have
provided, I recommend you to put the line of code
this.crystalReportViewer1.Zoom(75); after setting the report source. (Try
to move this line to the bottom of Form_Load.) Because setting the report
source might refresh the view, which causes Zoom not working properly.

I''m not quite sure why parameter issue happens. If you could send me a
repro with whole project, I will try to debug it. Thank you!

嗨凯文和NG，

再次感谢您抽出时间解决我的问题。在我收到
打包项目并发送给你之​​前，我想知道我是否会朝着正确的方向前进。首先，最重要的是Crystal Reports

（CR）是打印报告的正确工具吗？我的应用程序中有超过100个报告，我想使用最好的工具。


其次，如果CR是正确的工具我正确使用它吗？因为它很容易做到，所以我开始直接使用CR来对抗SQL数据库。这个

似乎被称为拉。关于CR的书籍技巧。对于我的

报告的90％，这将有效。对于最后10％，我将不得不重新格式化和/或

重构C＃程序中的数据。此时我可以创建一个

临时SQL表并打印报告使用相同的拉字段。技术I

一直使用90％，或者使用推送将其发送给CR。技术。我还没有学会推和推。技术。在我的ERP应用程序中，这样一份报告的好例子将是缩进的物料清单报告。这个

是一个遵循树形结构的报告，而不是表格中

记录（行）的简单列表。


第三，将.Zoom（75）属性移动到报告的末尾使得窗口底部显示的

消息显示为75％，但视图为

为100％。我可以使用窗口顶部的图标强制它达到75％。

现在通过代码设置的其他属性生效正确，例如

..DisplayGroupTree属性。

crystalReportViewer1.DisplayGroupTree = false;

crystalReportViewer1.Zoom（75）;


最后，报告加载事件是这段代码适当的地方？


和往常一样，谢谢你的帮助，


干杯，


Bob

新闻：Oj ************* @ cpmsftngxa06.phx.gbl ...

Hi Kevin and NG,

Once again thank you for taking time out to address my problems. Before I
pack up the project and send it to you I would like to know if I am going
off in the right direction. First, and most important, is Crystal Reports
(CR) the right tool for printing reports? I have well over 100 reports in
my application and I would like to use the best tool for the job.

Second, if CR is the right tool, am I using it correctly? Because it was
easy to do, I started using CR directly against the SQL database. This
seems to be called the "Pull" technique by books on CR. For 90% of my
reports this will work. For the last 10% I will have to reformat and/or
restructure the data in a C# program. At this point I could either create a
temporary SQL table and print the report use the same "Pull" technique I
have been using on the 90%, or send it to CR using the "Push" technique. I
have not yet learned the "Push" technique. A good example of such a report
in my ERP application would be an indented Bill of Materials report. This
is a report that follows a tree structure rather than a simple listing of
records (rows) in a table.

Third, moving the .Zoom(75) property to the end of the report made the
message that appears in the bottom of the window say 75%, but the view was
at 100%. I can use the icons at the top of the window to force it to 75%.
Other properties now set by code take effect correctly such as the
..DisplayGroupTree property.
crystalReportViewer1.DisplayGroupTree = false;
crystalReportViewer1.Zoom(75);

Finally, is the report load event the proper place for this code?

As ever, thank you for your help,

Cheers,

Bob
