View 7 RepliesI've got an app that manages estimates on jobs. When an estimate is loaded an e-mail has to go out to a list of people (different list for each job) that they should log in and approve the estimate. Least visible to the user making the estimate. Our should I research SQL mail and see if the sql box can handle it without the app user even knowing it?
View 2 RepliesI am trying to make a program that can calculate the percentage of people passing an exam. There are buttons for each letter grade, and working label counters for each time you press a button. Each button looks like this, except replace the letter with the appropriate one.
Private Sub btnA_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnA.Click
Static intA As Integer = 0
intA = intA + 1
lblA.Text = intA
lblPercent.Text = (lblA.Text + lblB.Text + lblC.Text + lblD.Text) / (lblA.Text + lblB.Text + lblC.Text + lblD.Text + lblF.Text)
End Sub
My problem is that the percent does not equal what I get when I put the exact same numbers into a calculator.
I want to make a program that will track Do Not Rent (DNR) People.I'm a intremediate vb6 programmer and have not coded in a long time.I do have and wanting to do this on VS2008 professional in VB2008.I did a simular program from a vb6 book about 12 years ago. it was a address book that i changed a little to add some things I needed it to keep track of, and it saved everything in a text file.I want to know what the pros and cons are for using a text file? xml file? or a data base?the data i be keeping track of will be vital statistics as name, state id number, id type, ect. and a picture of the id from a scanner or import from a .png, .jpg, or tiff image.If i use a data base file either Access 2007, MySQL, or SQL 2005/2008 file, do i need to have Office, MySQL, SQL 2005/2008 programs installed on the the computer im doing the programming on? do i need to have the above programs installed on the target computer?i do not think a txt file will work for me because of the picture i want to keep with the data not seperatly. So to make it a little more clear I want to be able to add, append/update, not to be able to delete a record, and be able to search the file for a record.I want to be able to navigate the records or file with first, previous, next, and last. each record will be showed seperatly.I would like to have a STATUS (lol thingy) that only my wife or I can change but let my employees be able to enter the rest of the information on there own. the STATUS Levels will be like 1st warning, 2nd warning, 3rd warning, DNR, and Rentable at our discression. I want it to only allow changes to status if they have the proper password. so i do not know if this also elimates txt files or xml files as an option.and when the wife, my employees or I make an entry I wanted it to add the time and date with the comments we entered in with the initials of the person whom entered the data. so i was thinking i will need to have security levels in my program and give each person a password so the program can fill out most small data itself.
if i do decide to use a database file to store the data, picture, and employee information can it be done with 1 table, or should i try to seperate the data in seperate tables? should i use one to one or one to many? I do not think one to many would be the best solution? it been like 12 years since I did any database programming in school and it was dBase3. If u think it be best to use multiple tables could u give me an example as to how to seperate the data.The client info would be like a address book with a picture and a comment box that will automatically add a date/timestamp and the users initials with a space between every updated or appended entry., and the employees would have there login in name and password, and initials.I was thinking of making a wizard to enter the data in for both employees and the DNR's as for people changing the date on the computer and entering info so to make it look they entered data on an earlier date I was thinking of having it log onto the internet time server and setting the date/time of the computer in the background as it loads up.

View 39 RepliesI have two areas on a form. One scrolls through patient visit details, the other scrolls through each patient's name and address, information like that. Is there a way that I can link these together so that as I scroll through one, the other scrolls as well? Meaning when John Doe shows in the left pane with his name and address, his appointment info shows at the same time on the right? It's using two different tables in the same data set, one for patient info and one for appointment info.

View 2 RepliesThe Calendar control (the Month Calendar) control in VB 2008. I am creating an attendance timesheet and I want the Calendar to color each date differently like e.g An employee Paul is selected from a list.
On the calendar I select the month. (The dates are not supposed to be selectable). Then lets say it is June. He is late on the 1st and the Second, so those days are supposed to be colored red (the whole block). Let's also say he is absent on the fourth and so I want that date to be coloured black. How do I do this? I tried finding a query and my friend told me that this functionality is not available in the current control and that I was best off making my own control (???).
I have tried selecting specific dates and bolding them (there is a function that allows this) but I am stumped trying to find two different ways to differentiate colours. Second:- How do I link a calendar with an Access Database?
After trawling around the net for a good few days, i decided to post something here.
Basically, i've got a problem linking a data source (Access 2007 database) to a VB 2008 project.
I've broken it down to having a problem dragging a table onto my form, when it generates the nav bar, it says "0 of {0}", and the table is empty (despite the actual database containing values)
However, this happens only at home, at college it works totally fine. The only difference that's obvious is that i'm using Windows 7 at home, and Windows XP at college.
I am working on a project that requires us to create a bracket type tournament and I am now stuck. I linked my access database to my project, and have 32 labels (lbl1-lbl32) and I cannot figure out how to integrate the labels to read from my database. It can be random or not, I just cannot get the labels to display the names of the fighters.
After the labels are integrated, the next coloum of the bracket has a link that opens a new window with each of the fighters match results, does the link have to include anything particular to display the attributes from the database?

View 5 RepliesSample in C# and VB.NET are OK.
I have a table "People" with the following columns:
-FullName (nvarchar not null)
-DOB (datetime null)
I want to write a LINQ to SQL to group the people by age, like following result:
Age 19: 4 ppl
Age 20: 5 ppl
Age 21: 6 ppl
Here's my try:
Dim query = From ppl In db.People _
Select New With {.Age = DateTime.Now.Year - CDate(ppl.DOB).Year, .CountAge = ppl.Count}
Notice that there are no DOB record for some people in the tables, so these shall not be included. The DOB column has record like this 1982-10-24 10:12:45 AM because it's a DateTime column.
