I am trying to do two things and I am having a conflict. I want to restrict the number of charcaters someone can type in a text box (numbers and letters) and also make sure all lowercase letters are changed to capital. For some reason my script works fine on numbers limiting them to 3 but I can type in as many letters as I want. How can I make the maxlength work for numbers and letters?[code]...

how to change multiple textboxes without calling each specific name. I have about 10 textboxes and would like to change their maxlength based on the following conditions.
1- If the user select decimal i would like to limit the maxlength to 3 on all the 10 textboxes at once versus individually changing each textbox maxlength.
2. If the user select hexadecimal i would like to limit the maxlength to 2 on all the 10 textboxes all at once.
Do you know how to set maximum length of character in the textbox of rdlc report? I already dug all of its properties but I didn't see any.
View 1 Repliesi am struggling with something quite elementary and simple. I am creating 200 dynamic textboxes with the following code :
[Code]...
Now, I need to restrict the user to type a maximum of 5 characters inside. The MaxLength property is supposed to help me with that, but the user is still allowed to type more than five characters!Later on, after I have crossed this bridge, I'll need to allow a minimum of five as well - so that the user will always be able to enter only five characters inside each textbox. Another problem in the future will be to allow only numeric digits. These are product codes, whic are always numeric, and always 5 characters in length

The problem is simple: I have a form with textboxes, and in one of those textboxes, I want users to enter either a positive or negative 2-digit number. I'm looking for an easy way to enforce this restriction, i.e. without having to parse the number and check whether its absolute value is below 100.

I got this error message when I only typed about 60characters. I have no idea why this happened to me since I have my address datatype set to varchar(100), I even had it set to varchar(MAX) at one stage but that made no difference. May I know what I've done?
View 2 RepliesWhen I drag a dataset onto a form (as details), is there a way in which the textFields maxLength property is automatically set with the width within the actual table. Or do i have to select each textBox and enter it manually?
View 1 RepliesIf you assign a string that is longer than the current value of the MaxLenght property, VB6 automatically trims the value to MaxLength characters, whereas VB.NET doesn't. Is there any way to achieve the same in VB.Net.
View 1 RepliesHow to add a child node to a specific node in treeview?
Say i have "Item1" in treeview already, How do i add "SubItem1" to "Item1" as it's child node?
I know its probably really simple, but i tried lots of stuff, i just cant get it working.
Basically, it refuses to find the node when the root node contains an attribute.

When I do xml.SelectNodes("DataSet") with the xmlns in the root tag, it finds no nodes. If I remove the xmlns attribute, it works fine.How can I make it work while leaving the attribute?

I have several controls on aWinForm (VS2010) which are bound to an SQL database table via a Dataset, BindingSource and TableAdapter (all bindings created via the IDE). When i try to update the daatbase table with changes made in the form controls using:
Me.QuoteHeaderBindingSource.EndEdit()Me.QuoteHeaderTableAdapter.Update(Me.BurdensCRMDataSet.QuoteHeader)
I'm getting the following error message: Cannot set column 'SalesTeam'. The value violates the MaxLength limit of this column Now on the surface the problem would seem self explanatory and the solution quite obvious. However i'm not changing the 'salesTeam' data, so it's exactly the same as it came out of the database and consequently it must be the same length. the data is two characters, the database field is a Char(2) data type and the datatable field has MaxLength = 2. So i can't see what's causing the problem or what i can do to resolve it
I've tried changing the data in the relevant textbox to just one character, but it still throws up the same error I've tried changing the SalesTeam DataTable field to MaxLength = 4, but it still throws up the same error I've tried reconfiguring the TableAdapter, but it still throws up the same error
I know my code is good because it works for other datatables that other controls in the same form are bound to. I'm I doing something wrong or missing something obvious or has anyone come up against this before

I've made a program that basically keeps track of all your CD Serial Keys. I've made the database and I'm at the point where I can type it all in and hit a "Add New" button to add it to the database, but when I hit the "Save" button, it crashes and says that the column "Serial Number" has exceeded the MaxLength....I don't get it...the numbers you put in the "serial number" is something like this "X5J3-2K4L5-2P4OK-23VMN-903NC" that's 24 numbers and letters long...I have changed the MaxLength property for the column to 30,000. How is 24 numbers and letters exceeded the MaxLength of 30,000? I think my "Serial Number" is setup for text. How do I fix this?
