I'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 1 RepliesI am trying to read the attributes of xml elements into a class which is then added to an array (I've tried the same thing with a List(Of T). For some reason, the last element is put into all the array positions. There can be a varied number of FactorParam elements each represent a different parameter and its relevant values. If there are two parameters, both positions in the array ActiveAGMP.FactorParamsArray will contain the values for param2. Likewise, if there are three parameters, all three positions in the array will contain the values for param3.
<FactorParam name="param1" type="string" id="1" value="Close" />
<FactorParam name="param2" type="integer" id="2" value="20" />
<FactorParam name="param3" type="integer" id="3" value="10" />

I have created a customized list (by implementing IList) where I added a few special methods. Sometimes (but not always), I only want to expose this list as read-only. To do this for normal lists, I use the Collections.ObjectModel.ReadOnlyCollection wrapper, which works fine typically. But it seems by passing my customized list through this wrapper, my added methods are no longer visible, which defeats the whole purpose of having this customized list object in the first place. How can I create a read-only version of a customized list?

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.

View 5 RepliesI'm completely new to .NET and am trying as a first step to write a text processing program. The task is simple: I have a list of 10,000 text files stored in one folder, and I'm trying to read each one, store it as a string variable, then run it through a series of functions, then save the final output to another folder. So far I can only manage to manually input the file path like this (in VB.NET):

I'm wondering, therefore, if there's a way to automate this process. Perhaps for example store all input file path into a text file then read each entry at a time, then save the final output into the save path, again listed in a text file.

I cut my programming teeth on QBASIC so apologise if I'm a bit behind the times. I wrote a program in QB and I'm trying to convert it to VB.NET.

View 13 RepliesHow would i read a set of names out of a file and then append them to a list box?I am not guaranteed a pair will be on the same line, and not guaranteed that a line would contain a maximum of one pair(i.e., it might have three pairs or it might have one and a half pairs - a first name, last name, and another first name whose matching last name would be on the next line). A line may also be blank.All of this needs to be in a visual basic format.
