98下为什么 Image.Picture.LoadFromFile('C:/btn1.bmp')　会造成死机现象呢？ ( 积分: 50 )

我的程序是在 XP + D7 下开发的，
后来用虚拟机装了个９８，将程序拷过去，结果造成死机。
后来检查，发现是
Image.Picture.LoadFromFile('C:/btn1.bmp')
这句话搞的。改成
Image.Picture.bitmap.LoadFromFile('C:/btn1.bmp')
不立刻死了，但一会后还会死机。
不理解是怎么搞的，请各位指教下。

你的图片太大了吧，不然换这个试试：
var
bitBuf:TBitmap;
begin
bitBuf:=TBitmap.Create;
bitBuf.LoadFromFile('C:/btn1.bmp');
image1.Canvas.Draw(0,0,bitbuf);
freeandnil(bitBuf);
（我在VirtualPC虚拟的Win98下运行正常elphi2005编译）

应为要处理 Image　控件的鼠标各种事件，所以不能改成　木桩,　老兄说的那样

图片文件只有4.13K

先用 fileexists('C:/btn1.bmp');　测试一下文件是否存在

已经判断了，文件存在。
而且就算不存在，也不应该死机呀。
程序在2000/XP下运行正常

这样跟你说吧，我刚才又试了一遍，
我只是简单的放了个 Image1，
procedure TForm1.Image1Click(Sender: TObject);里放的
无论 Image1.Picture.bitmap.LoadFromFile('C:/btn1.bmp');
还是 Image1.Picture.LoadFromFile('C:/btn1.bmp');
都不会出现死机。

建议你检查一下4.13K 的图片是不是 BMP格式的，因为Image.Picture.LoadFromFile读jpg也是可行的。
如果都不是，要不你把这部分的代码放上来...你说的太少了，看是不是由于下面的语句引起的死机？

啊？奇怪了，我就是写的最简单的程序测试了呀，难道是我的Delphi有问题，或者是虚拟机的Win98有问题吗？

编译后放入 98虚拟机中，点击button，图片显示，然后托动窗体，立刻死机。

虚拟机？不是吧，用真实的98也出错吗

我的那个程序，看看是不是D7的问题？我是Delphi2005编译的：
http://pitaten.blog.edu.cn/user2/26824/upload/20058183166.rar

再不你看看是不是虚拟机的问题啊，明明XP下能用的。

http://pitaten.blog.edu.cn/user2/26824/upload/20058183166.rar

哈哈，照样死机。
但是在Win2000、WinXP的虚拟机下不会死机。

老兄，会不会是你用虚拟机装的98有点问题呢？既然别的都没有问题，我想你应该怀疑一下你的98了！

就是，虚拟机的98出点问题了，我那个VirtualPC虚拟的还是原版的98，不是第二版的
而且可能是你的虚拟机问题？

你说的问题应该是bmp的版本问题，我也遇到过，你拿旧版本的photoshop打开再保存一次就没问题了，不知为什么delphi在98下打开新版本的bmp会出错

严重怀疑你的虚拟98有问题。你找一台真正的98去试试，应该没问题。

句子没问题，应该是其他问题。

to happychui,
我的图片的确全部是用photoshop cs编辑过的，然而现在发现有的图片不会造成死机，有的图片就会，而且已经用Phontshop 7.0重新保存过，依然死机，不知怎么搞的，难道是我转存成Ｂmp文件时的选项没设对？
保存时选择了Alpha通道，Windows格式，１６位。
对么？

Delphi里读取BMP时，还会读取调色板信息的，
你保存的图片原来存在调色板的话(像GIF)，会被留下来
看是不是Win98下读入有调色板的BMP出错？
http://pitaten.blog.edu.cn/user2/26824/upload/20058249935.rar

给你张带调色板的BMP，随便用个Image，设计时载入就可以看到了，颜色完全不一样。
