I want to know how to accept data from user? I want to accept about 10 datas from user. Before this I use Input box, but it is not a best way for user to key in 10 times data that required. What should I do and what the appropriate way to accept 10 data from user in 1 screen?
View 2 RepliesUsing a DataGridViewComboBoxColumn, the goal is to make the ComboBoxes accept user's new items and also the possibility of choosing items that are already present.I'm aware of using EditingControlShowing event of the DataGridView to change the DropDownStyle of the DataGridViewComboBoxEditingControl at run time to allow this, but I'm wondering if this can be done at a lower level.
What I'm doing now is extending DataGridViewComboBoxColumn, DataGridViewComboBoxCell and DataGridViewComboBoxEditingControl, hoping to change the EditingControl's DropDownStyle in the moment I instantiate it. So far, no luck.The debugger shows the right assignment is being executed, but nonetheless, the DropDownStyle is popping at the EditingControlShowing (using the event for debugging purposes) as DropBoxList, not DropBox, which is the intent.
Here follow the classes:
Public Class DataGridViewComboBoxColumnALT
Inherits System.Windows.Forms.DataGridViewComboBoxColumn
Public Sub New()

View 2 RepliesI'm trying to fill a ListView control in a VB2005 project. It works fine from underpinning (Access) database IF all the data is present. However, if a field is blank (in this case - a field called "Actual Date" which is meant to be blank for this record), the ListView will stop populating at that point.I thought this may have been the 'CausesValidation' property of the ListView but that doesn't seem to change the behaviour.Is this an inherent feature of the ListView - if so it seems daft - or is there a property I need to change or an override that I need to code?

View 3 RepliesI am designing a fairly small application to manage a waiting area for a clinical department. There will be a receptionist who books appointments and updates exisiting appointments to say that a patient has "Arrived". In seperate rooms will be nurses who call patients who have "Arrived" and update the appointment as "In Session" and finally as "Discharged". The appointments are viewed in a flexgrid with nurses across the top and time down the left, patient names are displayed at the relevant times and the cells are shaded a colour to represent the current appointment status ("Booked", "Arrived", "In Session" and "Discharged").
I am using SQL Server as the back-end and Visual Basic 6 (I know) as my front-end.I have been told that there will be 2 or 3 nurses plus the receptionist logged in to the system but I would like to cater for growth.My question is what is the best mechanism to use in order to reflect the status change made by one user on the screens of the other users currently logged in?
I have been thinking about using a timer to refresh the data at a set interval but I do not want to keep hitting the server excessively (although what is considered excessive? we would be talking about a call for data every 60 secs per user). Plus the server could be serving data for many other applications so this is another consideration.Alternatively I have been thinking about sending some kind of message via Winsock to the other users notifying them of data changes as they happen. I don't have a lot of experience with this and am concerned about clients not receiving messages and users seeing old data. It also seems strange to me that once the days appointments have been retrieved from the database that "in theory" a client could go the whole day without having to query the database again to pick up changes - kind of scary.Some information on the data:We would probably be looking at around 100 appointments per day We capture patient name, date of birth, date and time of appointment and appointment status.What is the standard approach / best practice for this kind of scenario?
I'm designing a PC-based app that has a little local database. I'm using VB.NET with SQL Server Compact Edition. The user will only ever have access to one database file, because it's all about storing a user specific data. However I'm thinking of the situation where there could be multiple users that access the PC, each with their own Windows account. So ideally I'd need separate database files for each User.
I'm not sure how to implement this. I was hoping to deploy the 'empty' database as a ClickOnce deployment, but I can't see how I can have a database per user doing this. Also I'm not sure where to store the database files anyway. perhaps in MyDocuments for each user? Or perhaps I need to stick to just one database, but add a 'User' column into every table, so it can hold data for every user. I didn't want to do this though - because I wanted to keep the nice separation between the data offered by physically separate files.
I need something tje user can type in data to such a parts QTY cost etc. There are no predefined parts list so the user can enter any part name/Number and there is no limit to amount of parts that can be entered.
Does anyone have any idea what might be useful. It was thinks of a listview bu i can't see that you can type into that. I cant use comboboxs because there are no predefined list and i know there is some way to generate text at runtime (i think) but i don't know how to do it and i would prefer a clearer approach.
i just write code for application, in which data is get by user and entered data is to print in a particular format?give me a code for vb.net button by which after click on it will print entered data?
