'这样调用

ISetOption()

vb.net里一个子程序可以用另一个子程序中的数据吗

可以使用，因为两个子程序的数据都是互通的，而且可以相互的补充，你用了另外一个子程序的数据也不影响你原本的子程序，这都是相互的

求vb代码 实现程序在系统托盘显示图标和气泡!!!!

Option Explicit Const MAX_TOOLTIP As Integer = 64 Const NIF_ICON = H2 '删除图标 Const NIF_MESSAGE = H1 Const NIF_TIP = H4 Const NIM_ADD = H0 '添加图标到任务栏提示区 Const NIM_DELETE = H2 Const WM_MOUSEMOVE = H200 Const WM_LBUTTONDOWN = H201 Const WM_LBUTTONUP = H202 Const WM_LBUTTONDBLCLK = H203 Const WM_RBUTTONDOWN = H204 Const WM_RBUTTONUP = H205 Const WM_RBUTTONDBLCLK = H206 Const SW_RESTORE = 9 Const SW_HIDE = 0 Private Type NOTIFYICONDATA cbSize As Long hwnd As Long uId As Long uFlags As Long ucallbackMessage As Long hIcon As Long szTip As String * MAX_TOOLTIP End Type 就是了

vb编的一个小程序，如何让他在点击右上角关闭按钮（就是那个叉号）时，在托盘 里继续运行？

VB6：

你可以在工程里多建一个窗体，操作的菜单写在这里，不显示9 OK了

当你要的窗体关闭后 再+载托盘

VB.NET里直接9有Closing和Closed事件

以下9是托盘：

vb.net执行sqlserver中的存储过程提示找不到

要解决这个问题，首先要确保存储过程已经在数据库中创建。如果存储过程已经存在，请检查您的Vb.Net代码，确保您正确指定了存储过程的名称。此外，请确保您的Vb.Net代码正确指定了数据库的名称，以及连接字符串中的用户名和密码是正确的。
