问题 Could someone please help me to mask the password entered to the input box generated using the below code. I will be using Office 365 ProPlus. Option Explicit Private Sub Worksheet_Change(ByVal Target As Range) Dim sPassCheck As String Dim rng As Range Dim sTemp As String Dim sPassword As String sPassword = "12345" sTemp = "You must enter the password to delete data" ' Check if target is within Range N6:N100000 If Intersect(Target, Range("N6:N100000")) Is Nothing Then If Target.Count > 1 Then

问题 This supposedly easy task gave me some headache. I simply want to let the user enter any text that succeeds float.TryParse into a Textboxish control. I could use a normal TextBox and check the Text in some btnOK_Click, but this is obviously lame. Also, there is a nice built-in MaskedTextBox control, but I failed to set it's mask to be equal to float.TryParse . Also, it seems to check for validity only when a focus change occurs. Digging around on the net brought some interesting ideas, but

问题 How can I use a MaskedTextBox to prevent the user from entering an invalid IP address? (I want it to behave just like the Windows one). 回答1: Try this: IPAddress ipAddress; if (IPAddress.TryParse(maskedTextBoxY.Text, out ipAddress)) { //valid ip } else { //is not valid ip } note: to use it, you need import the System.Net namespace: using System.Net; 回答2: Much simpler than the other answers: Use System.Net.IPAddress and System.Windows.Forms.MaskedTextBox set the following properties of the

问题 I have a MaskedTextBox in my Winforms application. I need a multiline mask on it, f.e: "999999\r\n 999999\r\n 999999\r\n 00/00/0000" I read the msdn documentation and was suprised to see that there is no "new line"or something like that. I know that i can write my own user control to fix this issue, but a masked textbox would be an easier solution. So i have 2 Questions: Is there a way to add a new Line to a mask? If not, why does the Control supports multiline - isnt that useless? Thanks in

问题 In my window application I need masked textbox which accept real decmal numbers. eg. 1) 1.56 2) 22.34 3) 123.34 4) 12312.34 This all value should be valid. Can anyone tell me how can I do this? And ya if anyone have better solution for real decimal numbers, instead of this masked TextBox than I love to see it.

问题 I have a MaskedTextBox with this mask (999) 999 9999. When user inputs a number the text property would give this to me : (0881) 444 5445 But I want to save the raw text to database field like this: 08814445445 . How can I do that? 回答1: Based on what I found here you can set the TextMaskFormat -Property to MaskFormat.ExcludePromptAndLiterals . That should be you solution. The MaskFormat -Enumeration holds some "options" for the MaskedTextBox. They are: ExcludePromptAndLiterals Return only

问题 Is there a way to use MaskedTextBox without displaying the PromptChar? I would like to specify a mask to validate input against, but I don't want any prompt characters to take up space during edit mode. The reason for this is when I want to accept free text with a limited character set, all characters are optional alphanumerics. The problem I have is that when I select all text, even the prompt characters are selected. Setting PromptChar to (" ") doesn't work. Setting it to Zero-width space (
