使用传统ASP如何从查询中返回图像.

我想在网页上使用图像进行跟踪,例如我可能有一个页面包含:

<img src="../cgi-bin/getimage.asp?user1234&page=1232" WIDTH="1" HEIGHT="1">

GetImage.ASP将记录传递的详细信息并返回透明GIF.

我似乎已经创建了破坏内存的代码.

从来没有遇到过这样的问题,我现在设置了一个无效的指针操作.

在下面,我调用PromptForXYZPropertiesSettings后,const字符串sFilename的值被删除.

// Allow the user to quickly display the properties of XYZ without needing to display the full Editor
function PromptForXYZProperties(const sFilename:string; var AXYZProperties: TXYZProperties): boolean;
var
  PropEditor: TdlgEditor;
begin
  PropEditor:= TdlgEditor.create(nil);
  try
    PropEditor.LoadFromFile(sFilename);                   <-- sFilename = 'C:\My Folder\Some Folder.txt'
    PropEditor.SelectedXYZProperties := AXYZProperties;

    // Bypass PropEditor to show form owned by it
    Result := PropEditor.PromptForXYZPropertiesSettings;  

    if Result then
    begin
      PropEditor.SaveToFile(sFilename);                   <-- sFilename now somethign like 'B'#1#0#0'ë' or value of a different var
    end;
  finally
    PropEditor.free;      
  end;
end;
