【中文标题】Delphi 组件安装实用程序控制台应用程序【英文标题】：Delphi components install utility console application 【发布时间】：2012-06-26 14:49:58 【问题描述】：好吧，我很难过。 我正在为 Smart Install Maker 编写一个安装支持插件，它将为我安装一些组件-AlphaControls :)
附加组件是一个控制台应用程序。但是由于某种原因 [在代码中] 将包添加到“已知包”注册表位置，它想要添加一个额外的注册表项，即使数组大小仅设置为 3。它正在尝试添加一个 .DPK 文件，即使该数组是为 .BPL 设置的。苏……什么鬼？？？？ 它可以正常工作，除了它试图添加的最后一个唠叨位。 编译大小约为97/98k，优化压缩后缩小到48k左右
所以我想我的问题是，谁能发现我似乎忽略的错误？ 是的，我知道 - INNO SETUP，但是...我已经把钱花在了 Smart Install Maker 上，所以我必须使用它。 没有编译错误，只是向注册表添加了一个额外的非 .bpl 文件
代码如下...

【问题讨论】：
你已经屈服于“沉没成本”的谬误。你在某件事上花钱了，你认为这迫使你使用它，但无论你是否使用它，这笔钱都消失了！您可以在不花任何额外费用的情况下获得更好的工具，那么谁在乎您在劣质产品上花了多少钱？假装你把它花在了免费产品上，如果这让你感觉更好的话。 【参考方案1】：您发出的问题似乎与用于迭代 BPLFiles 数组的索引有关。这是基于 1 的索引，而您使用的是基于 0 的索引。
const
BPLFiles: array[1..3]
of string = ('aceD7.bpl',
'acntD7.bpl',
'AlphaDB7.bpl');
更改此代码
for i:= 0 to BPLFileQty do
begin
RegName:= BPLPath + BPLFiles[i];
RegKey.DeleteValue(RegName);
end;
到
for i:= 1 to BPLFileQty do
begin
RegName:= BPLPath + BPLFiles[i];
RegKey.DeleteValue(RegName);
end;
还有这段代码
for j:= 0 to BPLFileQty do
begin
RegName:= BPLPath + BPLFiles[j];
RegValue:= BPLDetails[j];
RegKey.WriteString(RegName,RegValue);
end;
到
for j:= 1 to BPLFileQty do
begin
RegName:= BPLPath + BPLFiles[j];
RegValue:= BPLDetails[j];
RegKey.WriteString(RegName,RegValue);
end;
【讨论】：
都该死。我必须至少看了十几次那个部分，它正盯着我看。哈哈。我改变了它，现在它工作得很好。其他一些事情[上面未显示]也得到了修复。至于谬误，是的，我猜你是对的。但是由于您的帮助，它现在工作得很好，我保留了它。以上是关于Delphi 组件安装实用程序控制台应用程序的主要内容，如果未能解决你的问题，请参考以下文章
