为什么会抛出user32.dll中findtext未找到
最好来个有findtext使用的源代码的，急要做的效果跟ie8的网页查找差不多，查找的对象是一个treeview
支持模糊查询，要有上一个下一个

Answer 1

声明是这样
[DllImport("comdlg32.dll")]
public static extern IntPtr FindText(ref LPFINDREPLACE lpfindreplace);[StructLayout(LayoutKind.Sequential)]
public struct LPFINDREPLACE
{
    public uint lStructSize;
    public IntPtr hwndOwner;
    public IntPtr hInstance;
    public uint flags;
    public IntPtr lpstrFindWhat;
    public IntPtr lpstrReplaceWith;
    public ushort wFindWhatLen;
    public ushort wReplaceWithLen;
    public int lCustData;
    public LPFRHOOKPROC lpfnHook;
    public IntPtr lpTemplateName;}public delegate uint LPFRHOOKPROC(IntPtr HWND, uint UINT, uint WPARAM, long LPARAM);

为什么会抛出user32.dll中findtext未找到

Answer 3

findtext 在 comdlg32.dll 中，不是 user32.dll

Answer 4

那为啥网上搜索的时候全部说user32下面的findtext啊
