I am trying to manage the state of a MaskedTextBox based on the check state of a check box. If it's checked, looking to disable and clear the contents of the MaskedTextBox and if not checked, then to enable it and focus the cursor. For some reason, my logic is not doing anything. On initial load of the form, when I check the checkbox, the MaskedTextBox does clear and disable, but then it stays disabled.
[Code]...
I am using the MaskedTextBox and I am wanting to check for the following:
1. If the length of the text = 14 characters, enable the reset and start button
2. If the length of the text < 14 characters, enable the reset button, disable the start button
3. If the length of the text = 0 characters, disable both buttons
I am able to get most of it to work but when the length = 0, the start button is disabling like it's supposed to but the reset button is staying enabled. Any ideas? I have been looking at this code for hours and can't figure out why this is.
Here is the code.
vb Private Sub mtbClientPhoneNumber_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles mtbClientPhoneNumber.TextChanged 'Make sure that there is a phone number entered into mtbClientPhoneNumber. ValidateUserInput
[CODE]...
To see the form in action, you can see it here. The reset button isnt disabling when length = 0

I have noticed that there exists a specific option that needs to be enabled for the machine to hibernate correctly and that is found in Control Panel--> Power Options --> Hibernate Tab (if this option is not checked then the machine goes into stand by mode rather than hibernate) Is there a way to programmatically check the status of the "Enable Hibernation" check box and check/uncheck it?

View 2 RepliesFollowing some excersises I came across a visibility toggle for a menu item which does not seem to work:
Private Sub mnuMenuSize_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mnuSize.Click
If mnuSize.Text = "Short Menu" Then
[Code]...
If I click mnuSize on the menu it changes the text allright but leaves the visible property of mnuUnderline, another menu item, as it was. In the watch window before entering the click procedure mnuUnderline.Visible and "not mnuUnderline" are opposites allright(as they would have to be) but no swap occurs at the toggle line: mnuUnderline.Visible = Not mnuUnderline.Visible and the code doesn't report any errors either. mnuUnderline is indeed one of the available menu items. If I change the statement to mnuUnderline.Visible = mnuUnderline.Visible (bit of a weird statement allright) it will toggle exactly one time for no appearent reason.

View 3 RepliesI have a datagridview that is showing Yes and No in 2 checkbox cells. (Logically I should have just one checkbox but it is a legacy program (from Excel VBA)). So what I want to do is if the user clicks one checkbox cell to make the value True then the other checkbox in the row needs to be set to False. I have googled and searched the Forums here for an answer for this but found nothing really specific. The envisaged problem here of course would be that the events are mutual so they should not keep firing continuously in a "loop" when one or the other is changed - that might be the really difficult bit.
View 5 RepliesI have a piece of hardware that is controlled via USB.There are 8 LEDs on the output byte. One LED per bit.I like to toggle the outputs based on selection of checkboxes and given frequency entered in TextBox.I inserted 8 checkboxes to allow me to select the desired LEDs to be on.I select the checkboxes to select the required LEDs.The checkbox gives me the byte value. XORing the byte value with 255I can see them toggling very fast. I have a while loop to blink forever until I click on stop button.The stop makes the seq=false and this should stop the blinking but it keeps going.How can I insert desired delay of flashing frequency in my output routine?How can I stop on demand to change pattern without exiting the program.
View 2 RepliesI am really new at writing macros and want to keep them simple, but can't quite get this one to work. Here it is:
Sub HighLight()
Dim switch As Boolean
switch = Not switch[code].....
I created a toggle button and assigned this macro to it. However on the first click of the button, it only executes the first half of the macro--highlighting the requested cells yellow. Yet, when I click the button again, it does not turn the cells back to the un-highlighted state. From querying the web, most examples use the If-Then-Else.This is a macro that I got off the web and it works beautifully (and simply written):
Sub ToggleHideRows()
For Each cell In ActiveSheet.Range("H:H")
If cell.Value = "X" _[code].....
I was trying to write the first macro to act in quite the same manner as the second macro. Also, with the first macro I would like to add "cell.Offset(0, -7)" along with "cell.Offset(0, 2)".
How can I toggle the selection of a datagridview row?If I pick the Row once it should "highlight"If I pick the same row again I want it to "unhighlight"this is what I have so far in a mousedown event:

DataGridView1.ClearSelection()
End If
I'm fairly new to VB.net and this is my first post on this forum.I'm creating a website in Visual Web Developer 2010 Express in ASP.NET/VB and I'm trying to find out how to alternate a Reponse.Redirect, basically I'm looking to redirect every other visitor to go to a different site.
For example:
Visitor 1 gets: Response.Redirect("http://site-a.com")
Visitor 2 gets: Response.Redirect("http://site-b.com")
Visitor 3 gets: Response.Redirect("http://site-a.com")
Visitor 4 gets: Response.Redirect("http://site-b.com")
and so on
Also, if there is a way to set a cookie for that visitor, so if they visited within let's say the last 90 days, they will go to the same site they visited before, and not be redirected by the Response.Redirect.

View 3 RepliesI have a page which is used to display numerous forms for the user to fill out and get reports generated. Each of these forms is inside it's own ASP:Panel control so that I can toggle the visibility of the form (so that only those with appropriate permissions get access to the reports they are allowed to).
The client has now requested a "table of contents" like area on the page with hyperlinks pointing to each of the forms (so that they don't have to spend time scrolling the page to find the particular report form they want). This is easy to accomplish using standard <a href="#Area"> and <a id="Area"> tags. What I am now looking for is a way that would allow me to hide the links of reports that the user does not have access to.
I was first thinking of using the ASP:LinkButton control, but I do not want any postbacks to occur from clicking the links (that would be very unnecessary). Are there any other methods I could use to accomplish the same goal? I am looking for something which would make it easy for me to toggle the visibility of the corresponding link at the same time I am toggling the visibility of the panels containing the report forms (done now from the code-behind).
