问题描述
大家好,我的项目有问题.我想做的是如果那里的计数大于等于2,则显示禁用按钮.但是,如果busNumber = txtbusNumber.text和date = txtDay.text并且count = txtCount.text,则需要这样做.
所有这些都存储在数据库中.即使计数正常,我也可以检索它们.
这是我到目前为止的代码.
Hi guys, am having a problem with my project. wat i want to do is display disable the button if there count is greater than equals to 2. but need to do so if busNumber = txtbusNumber.text and date = txtDay.text and count = txtCount.text.
all this are stored in the database.. i can retrieve them all even the count is working.
this is the code i have so far.
if txtBusNumber.Text = "AT01" And cmbDay.Text = "Monday" And txtCount.Text >= 2 Then
txtNotification.Text = ""
btnConfirm.Enabled = False
txtNotification.Text = "Sorry Bus from " & cmbDepart.Text & " to " & cmbDestination.Text & " is fully booked"
Else
btnConfirm.Enabled = True
txtNotification.Text = "Ticket Available"
End If
请帮助..谢谢
please help.. thanks
推荐答案
我认为这不能编译?如果txtCount.Text是一个数字,则应该使用int.TryParse进行计算,如果是,则可以进行比较.我不明白您余下的问题,您在这里还要问更多吗?什么是busNumber?如果它是变量,为什么不与之比较?
I assume this does not compile ? You should use int.TryParse to work out if txtCount.Text is a number, then if it is, you can compare it. I don''t understand the rest of your question, is there more you''re asking here ? What is busNumber ? If it''s a variable, why not compare to it ?
您需要将txtCount.Text> = 2替换为"Convert.ToInt32(txtCount.Text)> = 2"
you need to replace txtCount.Text >= 2 with "Convert.ToInt32(txtCount.Text) >= 2"
昏暗计数为整数
计数= Convert.ToInt32(txtCount.Text)
如果(count> = 3)并且cmbDay.Text =星期一"和txtBusNumber.Text ="AT02"然后
btnConfirm.Enabled = False
txtNotification.Text =巴士已满"
如果结束
不是在init下,而是在命令下
Dim count As Integer
count = Convert.ToInt32(txtCount.Text)
If (count >= 3) And cmbDay.Text = "Monday" And txtBusNumber.Text = "AT02" Then
btnConfirm.Enabled = False
txtNotification.Text = "Bus Fully Booked"
End If
not under init, but under command
