c#怎么获得桌面图标的位置,并让坐标动起来

[zhangzhaoyang]

我做了个小精灵和QQ宠物是的,我想让它在桌面走的过程中碰到打开的窗口可以顺着窗口怕上去,如果碰到桌面上的图标就一脚踢开,图标飞到其他地方去,大虾们这应该用到哪个WIN API 啊,?我找了好几天不知道怎么弄,请指教,最好有源码,在线等,解决立即给分!

哇,这个。。。。。比较难！建议你还是把问题具体后再来提问吧，

就是怎么获得桌面上图标的坐标和设置它的坐标

[破碎的脸]

如果说要得到桌面上的图标位置这个估计很是麻烦，但是设置自身的坐标这个就比较简单了。

参考如下代码：

得到桌面某个图标放置的坐标

uses CommCtrl;
procedure TForm1.Button1Click(Sender: TObject);
var
vHandle: THandle;
var
vItemCount: Integer;
I: Integer;
vBuffer: array[0..255] of Char;
vProcessId: DWORD;
vProcess: THandle;
vPointer: Pointer;
vNumberOfBytesRead: Cardinal;
vItem: TLVItem;
vPoint: TPoint;
begin
vHandle := FindWindow('progman', nil);
vHandle := FindWindowEx(vHandle, 0, 'shelldll_defview', nil);
vHandle := FindWindowEx(vHandle, 0, 'syslistview32', nil);
vItemCount := ListView_GetItemCount(vHandle);
GetWindowThreadProcessId(vHandle, @vProcessId);
vProcess := OpenProcess(PROCESS_VM_OPERATION or PROCESS_VM_READ or
PROCESS_VM_WRITE, False, vProcessId);
vPointer := VirtualAllocEx(vProcess, nil, 4096, MEM_RESERVE or MEM_COMMIT,
PAGE_READWRITE);
try
for I := 0 to vItemCount - 1 do
begin
with vItem do
begin
mask := LVIF_TEXT;
iItem := I;
iSubItem := 0;
cchTextMax := SizeOf(vBuffer);
pszText := Pointer(Cardinal(vPointer) + SizeOf(TLVItem));
end;
WriteProcessMemory(vProcess, vPointer, @vItem,
SizeOf(TLVItem), vNumberOfBytesRead);
SendMessage(vHandle, LVM_GETITEM, I, lparam(vPointer));
ReadProcessMemory(vProcess, Pointer(Cardinal(vPointer) + SizeOf(TLVItem)),
@vBuffer[0], SizeOf(vBuffer), vNumberOfBytesRead);
if SameText('我的电脑', vBuffer) then
begin
ListView_GetItemPosition(vHandle, I, PPoint(vPointer)^);
ReadProcessMemory(vProcess, vPointer, @vPoint, SizeOf(TPoint),
vNumberOfBytesRead);
Caption := Format('%d,%d', [vPoint.X, vPoint.Y]);
Break;
end;
end;
finally
VirtualFreeEx(vProcess, vPointer, 0, MEM_RELEASE);
CloseHandle(vProcess);
end;
end;

哈哈.有意思...

有时间我也做一个...

[zhangzhaoyang]

大哥,别光自己做啊,会做也教教我啊,我都快急死了,好几天都没睡觉了,急用

[zhangzhaoyang]

亲哥哎,俺看不懂DELPHI,啊.WIN API也刚刚看，不会改啊，能不能给个C#的啊,我用的是C#

[fengjun19912]

学习下

[zhangzhaoyang]

ListView_GetItemCount这是一个什么方法啊??
api 没有啊??
能不能把常量列出值来啊,C#不识别这种常量啊~~~~
只要能解决问题我会多加分的~~~

这个？

的确有意思, 我好久没见我的qq宠物了 55555555

[zhangzhaoyang]

就是要获得桌面图标的位置,然后用程序去设置它的位置

[zhangzhaoyang]

大哥,桌面图标不只是固定的几个啊,还有自己定义的一些图标,都要获得.WIN API我以前没弄过,最近刚开始看，看不大懂啊,能不能给点能在C#里用的,详细点的啊,或者联系我QQ吧,124344664

自己顶一下

老实说，真的没看懂，大师，有C#的吗

[zhangzhaoyang]

哥们你太牛了,我找了好几天了都没找着C#的,谢谢了,我这就结帖去,给分!

[zhangzhaoyang]

所有的分都给你吧!!!100分
