Pull Data From A Sql Query?
Mar 23, 2009
My program pulls a weeks worth of records at a time and filters it into daily columns on a form, the problem is that there are ~80 fields to be filled in this manner and as far as i know each one has to be check for null before it can be filled. Could someone tell me if there is a faster way to do this? Below is my current code for one set of fields.
Private Sub cboDigit_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cboDigit.SelectedIndexChanged, cboOffice.SelectedIndexChanged, dtEndDate.ValueChanged, dtStartDate.ValueChanged

I've written a bunch of queries that bring back a set of results that look like the following. I have a user level column in an employees table which I'm trying to pull the value from. Only one result (number) will ever be returned. For instance the query will be like: Select username, userlevel from employees where username = "joe" So i'd be bringing back just the level, say 7.

I have two comboboxes and a listBox to display data from several databases. The whole process should be that after an option is selected in the first comboBox, the second comboBox and the listBox are populated. So for example, I could select a Company from the first comboBox, and the second conboBox will be populated with all it's locations while the listBox will first display the location of the headquarters(default location). But the user can then select a different location from the second comboBox if they want to and the listBox will then display the location of that newly selected office location.how do I dynamically pull these data from various databases cause all the companies will have their information in separate DB's. My challenge is how to dynamically pull these data from the various DB's to populate these 3 controls.

I'm having a problem to pull data from MS Access to my combobox. I know how to search one data using another data (e.g: using IC num to search name) but this time I just want to pull the data (e.g: name) that has several rows to my combobox. I think the method is the same but don't know where to change it.
Then when I added new names to the combobox, want to save it to my database, can each name be saved in different rows? I added the names to the combobox 1st, after that then I saved it. [code]...

EG: Cstr=Connstr("OrDB")
The known name of OrDB would result in a string assigned to the variable Cstr that could be a connection string to an oracle database.

I have a form as shown below:
And a database as shown below:
It is an inventory program I am doing on the side just to keep track of a small number of supplies, I want to be able to enter a barcode and have the program see if it already is in the inventory database, if not, it will allow me to enter information and add it to the database (That part works - Thanks to member on D.I.C.) If the barcode exists, I want it to fill the form with all the data from the database and allow me to update fields such as date used and used definition

I have a VB 2010 program with a single-table Access Database.I have selected the option to copy the Access Database to the output directory.When doing so, the program copies the original database to the inDebug folder.I want the original (NOT the copy) to be modified when the program is being tested.Also, when I attempted to publish the program and run it to test, I got an error which was sourced to be a temporary file (which was the database) that was missing.I think this is a reaction from the "Copy Always" option.

I have been searching and searching and cannot find out how to do what I'm looking to do, that is the only reason I would post a new thread.[code]...
After reading the file, I want to load the NameId, the ColourId and the Text into a multidimensional array. Anything I have found about loading into an array shows text being separated by small delimiters like commas, but this I cannot do because I need to use this format. What I am wanting to do is load all of the NameId's into a listbox and when a certain NameId is selected, it will bring up the Text in a TextBox and the Colour value in a ComboBox.

I am attempting to create a basic program and I need to know how to incorporate INI files for profiles in order to quickly pull up data from one person to the next.
Public Class IniFile
' API functions
Private Declare Ansi Function GetPrivateProfileString _
Lib "kernel32.dll" Alias "GetPrivateProfileStringA" _
[code]....
And placed it into a module, which I then wen't to my main program and attempted to place this:
Dim ini As New IniFile(Profiles.ini)
Dim value As String = ini.GetString("Names", "1", "Default Value")
To attempt to retrieve the data, but I get no error or information from it. The ini file is inside the folder of the project and I set the SectionName and KeyValue to the corresponding names. I think I am having trouble with syntax? Not 100% sure. This is the code that I got from the same source as the module for using the module.
Dim ini As New IniFile(FileName)
Dim value As String = ini.GetString("SectionName", "KeyName", "Default Value")
And I adjusted to what I believed would be the proper format.

I 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?
