曾经在VS2005时,找了很多资料折腾了一个通宵把网页本地打印折腾出来了,微软的有些东西虽然好用吧,报表这个总是弄不好一样,非常想念Microsoft Visual FoxPro 的报表,大概都是10年前的事情了,用那个VFP做报表,又好用又简单,功能也很强大,特别是排版非常容易,不知道微软都在搞啥网页报表就是折腾总是会遇到很多问题,IE8以前的版本的网页打印也很若,非常闹心,想实现一个最简单的网页打印功能就好比上天一样折腾人,也可能是我的水平有问题吧,不过我们很多同事也弄不好这个。
接下来直接谈我的折腾过程:
1. VS2008 安装好后,应该是自带一个 CrystalReports ,总感觉 CrystalReports 不是微软的,好像是被SAP收购了一样,具体我不是很清楚,而且各种版本特别多,有时候到底要引用哪个版本也是让人头疼一些。
2. 想实现本地打印,我总感觉需要下载一个微软的 ReportViewer,而且是For VS2008的,也有For VS2005的,我也没测试过这个是否是必要的组件,装上就可以了,这个是在网页里显示报表用的。
3. PrintControl 比较折腾人,也后很多版本的,For VS2008 需要在网络上下载,写明链接的地方非常少,http://support.businessobjects.com/CRforVS2005/PrintControl.cab 这个地址是 For VS2005的,我自己想象了一下把2005修改为2008后,能下载 For VS2008 具体地址如下 http://support.businessobjects.com/CRforVS2005/PrintControl.cab
4. 写一个html文件,自动安装ActiveX控件,这样报表就可以在本地打印了,若还不行,别忘记重新启动IE,重新启动电脑,还不行,就升级到IE8,再不行,先休息一下,再到网络上找找其他资料吧。
<html>
<object id="CrystalPrintControl" classid="CLSID:83A3D1E4-ADC6-434D-9B61-B8CBA6183441"
codebase="http://www.cnblogs.com/../UploadFiles/ActiveX/PrintControl.cab" version="10,5,1,2285"
viewastext>
</object>
</html>
这里就是 classid、version 等的配置比较闹心,因为不同的版本,这些号码都不一样,若对不上,就会崩溃了,
先通过这个网页,可以先把客户端打印的控件装上。
5. 接着就是配置 web.cong 了,我把我的配置文件贴上来,有需要的朋友可以参考,这里需要注意的是
<section name="printControl" type="System.Configuration.NameValueSectionHandler, System, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089, Custom=null" />
这里的Version也有很多种类的,我按最新的10.??多少一用,就会出错,我又退回来用这个,程序就正常了。

8. 若报表预览时,打印按钮、导出按钮没有出现,很可能是服务器上的配套图标文件放错位置了,需要注意
\aspnet_client\system_web\2_0_50727\CrystalReportWebFormViewer4\?
这些文件需要放在 wwwroot 下,就是IIS的根目录下才可以,否则也无法直接打印输出到本地。
网上有人讲:水晶报表显示 工具条上的 导出、打印、刷新按钮 都是显示为 一个个的 小红叉 似的。点击以后打开一个当前页的新窗口,却没有生成为PDF或者打印。 但是在程序 调试和 在浏览器中查看 的状态下都是正常的。都折腾好几天了,还是没解决问题。这个问题,就是上面的事情导致的,按我讲的折腾一下,就应该会好的。
技术再厉害,遇到问题都需要摸索,这次是第二次折腾这个,以前折腾过的经验很多都派上了用处,还比较顺利一些,
但是还是用了4-5个小时才把问题都解决好,所以我把经验写下来,分享给将来需要的人查阅,尽量少浪费宝贵的生命,时间就是金钱,我们不是弄不出来,或者做不出来,而是看能否在最短的时间里见效,只要给我时间,我什么管理系统都能做出来,但是等我做出来,我的客户都倒闭了,还要这个东西干啥用啊,黄瓜菜都凉了。
以上文章,希望能对有所需要的人起一点儿帮助作用,或者遇到麻烦了,可以参考一下,还有一些人不知道如何
将报表进行本地打印的,报表可以在本地导出各种格式的文件,有大部分人不知道报表可以本地打印的。
将权限管理、工作流管理做到我能力的极致,一个人只能做好那么很少的几件事情。
