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.
[Code]...
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 3 RepliesApologies for the long post, but I would be very greatful for any advice given. I have developed a visual basic application to communicate with a device through a COM port. This application works fine. The device connected to the COM port sends information relating to the status of the device, this information is read in using VB and inturn written to an SQL database. Using the visual basic application the user can also send commands through the COM port to the device. The application scans the users computer and detects all available COM prots, these are presented to the user and they can select which one to connect to. The COM port is held open for the entire period that the program is in use (this is to allow for the incomming information to be read)

View 8 RepliesI am using Umbraco (a .NET CMS), and it has a reference to a specific version of a DLL (see 1 Umbraco Reference below). This is fine until I try to hook into the .NET MailChimp API which references a different vesion of the same DLL (see 2 PerceptiveMCAPI below).I can think of a couple of options for resolving this
a. Get either the Umbraco or PerceptiveMCAPI source and reference the same version of the DLL, really do not want to do this for compatibility reasons
b. Dump the 2 DLLs in the GAC, I want to avoid this as I see deployment issues arising if someone forgets (I know we should have an automated deployment but time is restricted)
I remember that there is a third option to specify what version of the DLL to use in the configuration. Is this possible and what is the code for it?

I've got a bound Combobox in a database for a lookup but when i set it up and change the data in the combo the program won't let me go and further. There is a data conflict but i don't know where. The problem is here in the combo setup:
Display member : ProductName (nvarChr(20)
Value Member : ProductID (int)
Selected Member: SelectedLookup (int)
This doesn't work. Everything is displayed in the dropdown by name but when i select a item. I can't go any further. If i change the Display member: to 'ProductID' the program works fine. but displays the ProductID where users won't understand. It's like it is trying to store the 'displayed member' Product Name instead in the Value Member 'ProductID'. if i use a list box instead the program works correctly.
I've been encountering this problem. When I add a listbox at my game, all my keypress events and codes doesn't work. But when I remove it, it will work again. I don't know what's the problem. I need the listbox to add strings on it for my game.

View 7 RepliesI have a datagridview in which the user can add new rows. The datasource is a datatable who has a unique-constraint for the column "Position". Thus, if the user enters a position already existing, an exception is thrown. To avoid the ugly standard error message, I simply handle the dataerror-event and set e.cancel = true. This works. But if the user presses escape, the row_validated-event is triggered. I use this event to format the rows containing new data by changing the font color to red. Here another exception is thrown (SystemOutOfRange-Exception) telling me that the index xxx has no value. How can I achieve row-formatting for new/modified entries without getting this error?
Here is my code:
''' <summary>
''' Catch exception and cancel illegal action.
''' </summary>
''' <param name="sender"></param>
''' <param name="e"></param>

View 2 RepliesWe were using Ofiice 2003 since long but now we are migrating to Office 2010.The problem that we facing now is that in our Workbook based on Excel 2003 we had a few ranges with names like BCD1, DOT1 but now in Excel 2010 BCD1 and DOT1 are cell names. The new version changes the BCD1 to _BCD1 automatically but we have to manually change the Macro code for the same which is a cumbersome problem.

I write an HTML file with MS Word, and use it on my application. The problem is that I need to close Word or Visual Studio in order to save the file, or compile the code, because each one reserves the file permission rights. The html file is only written by word, and only read from VS. At compile time, the file is copied to execution directory. Is there a way to give both programs simultaneous permission rights?

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
