View 17 RepliesHow do I make it that the user must enter a number between 1 and 100? And If they dont they get an OK messagebox stating that they must do.I imagine it'll be something like this:
If TextBox1.Text = "" Then
MessageBox.Show("You must enter a value between 1 and 100", "Name Entry Error", _
MessageBoxButtons.OK, MessageBoxIcon.Exclamation)
End If
But Im not sure whats suppose to go inbetween the speech marks.

View 4 RepliesIf we format a value for percent "{0:#%}" then it will become 400%, and this also applies to all the 3rd party controls I've tried. I've used custom format as a workaround for this but perhaps you guys could enlighten me on this one. If a user inputted 4 for example then did the user intended 4% or 400%? If it were me that I would expect the 4 to be 4% rather than 400%.

I need to write a program allowing the user to enter up to five passwords at one time. I have the textboxes set the way I need. When the user presses the button, the code should check every password they ve entered, and flag any passwords that are invalid. A valid password includes the following:
At least 6 and not more than 15 characters
At least one uppercase alpha character
At least one lowercase alpha character
At least one numeric character
I'm a little confused about how to check each character of the entered passwords for these conditions.Because it must include alpha characters, I believe I have to do something with ASC and CHAR variables. This is my first post and I need to have this done within a few hours, haha. Help would be awesome.

View 5 RepliesI'm trying to figure out how to prompt a user to enter a captcha. Some programs out there have a little popup with the captcha image and a textbox, the user then enters the characters from the image and the captcha is solved by the user of the application. When I try to request the image directly, it gives me a different image than the one currently in the webbrowser control. Any ideas how I can create the pop up of this captcha image for the user to enter?

I have an autocomplete textbox in vb.net. It is working fine, but now I need to pop up the window again when the user hits enter or double clicks. So far, I know that when the user hits enter, the keydown event raises with e.kecode = 13. I guess my code would go here. My problem is how do I tell autocomplete to start again after the user hits enter??

The situation: I have a datagridview with one column (col1). In the datagrid definition (design view), i have created this row, and set the formatting to C2 (or C0, or C - I tried them all). then, I load my datagrid view pro programmatically :
dbl_myValue as double
dbl_myValue = 6.99
datagridview1.item(0,0) =
dbl_myValue
The datagridView shows the data correctly : 6.99$. When I "spy" on the datagridview.item(0,0), the "Value" property is a Double.
the problem: It don't work if the user manually enter a value : click in the cell, enter a numeric value (let's say 100, without decimal to avoid complexity) and then LEAVE the cell (so no more in EDIT mode). The formating just don't applies. When I "spy" on the datagridview.item(0,0), the "value" property is a STRING. So I guess this is the problem, but how can i do?
I want to limit and verify the textboxes data which enter by the user i want to make a class in which i pass the textfield and the methods in that class return boolean value . First method check only numbers with decimal point. second method check only A to Z or a to z with some specify charecters. In java it is very easy by the parse INt methods or use class.
