我知道可以从用户的墙上或Feed中获取所有帖子,但我在API或文档中找不到任何显示如何从页面获取帖子的内容.
看看http://facebook4j.org/en/api-support.html#page,看来实际上有一组与页面相关的方法,但点击其中任何一个只是刷新页面,让我觉得也许他们有计划但尚未实施？
我知道可以使用图形API从页面获取帖子,但如果可能的话,我真的更喜欢坚持使用Facebook4j.
任何投入将不胜感激!
我正在寻找如何自动将键盘焦点设置为PowerShell中的文本框.
我有一个脚本要求用户从下拉菜单中选择一个选项,然后根据该选择,他们必须输入某些参数.一切正常.
为了便于使用,我希望每次显示新键盘时键盘的焦点都会移动到输入框,这样用户就不必一直点击它来输入一些文本.
我的代码到目前为止:

$objForm.Text = $parameter

$objForm.KeyPreview = $True
$objForm.Add_KeyDown({if ($_.KeyCode -eq "Enter")
{$paramValue=$objTextBox.Text;$objForm.Close()}})
$objForm.Add_KeyDown({if ($_.KeyCode -eq "Escape")
{$objForm.Close()}})
$OKButton = New-Object System.Windows.Forms.Button
$OKButton.Location = New-Object System.Drawing.Size(75,90)
$OKButton.Size = New-Object System.Drawing.Size(75,25)
$OKButton.Text = "OK"
