View 4 RepliesI 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]...
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 1 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>

I am writing a backup process.
Step1: User selects 3 times (Tuesday 1am,3am,10am or Everyday 1am,3am,10am)
Step 2: The application should check the time settings and start the backup process automatically.
Is it possible to start the backup process if the application is not running?

I have a MenuStrip with several items in it. All I am trying to do is select(check) only one item at a time.
Example: Lets say I have a menu title Fruits, and under the menu are several fruits.
Currently, when I click on one fruit there is a check mark, good! The problem is when I click on another fruit there is also a check mark and so on.
