VB.NET中能否做一个像QQ那样的聊天框，可以输入文字和图片？

第二个问题 vb.net插入数学公式 可以把这些公式封装到一个类中，调用就是了

VB.NET中，如何动态创建非模态窗体，类似于QQ一样，双击一个头像会弹出一个窗口。

做一个窗体模板，假设是Form2

Dim x as New Form2

x.Show()

如果弹出窗口较多，x可以用动态数组替代

VB如何实现仿QQ消息盒子效果

终于写完了，累死我了、

在窗体上添加一个Timer控件，interval的值设置为1000，也就是周期为1秒。

然后再添加一个Form2和一个模块

form1中的代码

'--------------------------------------------------------------------------------------------------------------------------------------

Option Explicit

Private Type POINTAPI

x As Long

y As Long

End Type

Private Declare Function GetCursorPos Lib "user32" (lpPoint As POINTAPI) As Long

Private Declare Function GetWindowRect Lib "user32" (ByVal hwnd As Long, lpRect As RECT) As Long

Dim HJonny As POINTAPI, mForm As RECT

Private Sub Form_Load()

Me.Hide

Load Form2

End Sub

Private Sub Form_MouseMove(Button As Integer, Shift As Integer, x As Single, y As Single)

Timer1.Enabled = True

End Sub

Private Sub Form_Queryunload(Cancel As Integer, unloadmode As Integer)

Cancel = True

End Sub

Private Sub Timer1_Timer()

Dim x, y

GetCursorPos HJonny

GetWindowRect Me.hwnd, mForm

x = HJonny.x

y = HJonny.y

If x mForm.Left And x mForm.Left + (mForm.Right - mForm.Left) And y mForm.Top And y mForm.Top + (mForm.Bottom - mForm.Top) Then

Else

Me.Hide

End If

End Sub

'----------------------------------------------------------------------------------------------------------------------------------------

form2中的代码，首先在Form2的窗体上右键---菜单编辑器，在标题处输入 文件(F) ，名称处输入 Files ，再在底下的列表框中第一行"文件(F)"这个的下面，也就是第二行，点一下，会选中一行空白，再点一下上面的黑的冲着右面的小箭头，然后再在上面标题处输入 退出(E) 名称处输入 Exit 然后点确定。代码如下！

Left As Long

Top As Long

Right As Long

Bottom As Long

End Type

Const SPI_GETWORKAREA = 48

Public Declare Function SystemParametersInfo Lib "user32" Alias "SystemParametersInfoA" (ByVal uAction As Long, ByVal uParam As Long, ByRef lpvParam As Any, ByVal fuWinIni As Long) As Long

Public Function GetTaskbarHeight() As Integer

Dim lRes As Long

Dim rectVal As RECT

lRes = SystemParametersInfo(SPI_GETWORKAREA, 0, rectVal, 0)

GetTaskbarHeight = (Screen.Height / Screen.TwipsPerPixelX) - rectVal.Bottom

End Function

Public Sub Form_ShowUp()

Form1.Move Screen.Width - Form1.Width, Screen.Height - Form1.Height - (GetTaskbarHeight() * 15)

Form1.Show

End Sub

好了，希望能对你有帮助，自己写的，代码不太工整，见笑。。

VB怎样仿QQ的截取影片图像

Option Explicit

Private Declare Sub keybd_event Lib "user32" _

(ByVal bVk As Byte, _

ByVal bScan As Byte, _

ByVal dwFlags As Long, _

ByVal dwExtraInfo As Long)

截全屏的:

Private Sub Form_Click()

keybd_event vbKeySnapshot, 0, 0, 0

DoEvents

Me.Picture = Clipboard.GetData(vbCFBitmap)

End Sub

VB.net什么控件能实现像QQ表情栏那样存放连续图片

VB.NET标准控件库中是没有这个控件的，不过既然提供了picturebox，类似你说的这样的可以连续存放多个图片的控件是可以通过代码动态添加控件来实现，也可以通过vb.net中的GDI+函数代码编程实现。

VB NET,像QQ登录界面、酷狗那种窗体是怎么做出来的？

这个问题很简单，但是，要自己去写事件，不然，窗体就是一个死窗体了
