View 8 RepliesI am using VB.net code and SQL server 2005.I am havng below code for sending email in my vb.net code.
Protected Sub ibtnSendInvites_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ibtnSendInvites.Click
Try
Dim emailList As New List(Of String)
For Each curRow As GridViewRow In GridView1.Rows
[code].....
Now my problem is that some time if emailaddress is not valid or SMTP server is responding my application get hangs. I want to log my errors generated by my SMTP server in table or any log file it would be good if I can send back email to admin with the details of error occurred.
In my VB.net code i have:
cmd.CommandText = "SELECT * FROM [strfg].[dbo].[Myfunc] (@MyParam)"
Dim myparam As New SqlParameter("@MyParam", a)
cmd.Parameters.Add(myparam)
The function (runnig on SQL server) returns a table with four columns, one row.How do I call this function from Visual Basic? cmd.ExecuteScalar() is obviously not correct. In c++ I use a recordset. What is the equivalent in vb? Does anyone have a short example?
I'm willing to compare a textfile (whatever) which contains a few lines of text. After the comparison it should download and replace the "changed" folder/file. E.g.
(Local txtFile)
maps: 1.0.0
db1: 1.0.0
db2. 1.0.0
(Server txtFile)
maps: 1.0.1
db1: 1.0.0
db2. 1.0.0

I have a table with a column/field (type : nvarchar) that stores text. The text is read from a text file and written to the database using vb.net application.The text in the text file contains Turkish characters such as the u with 2 dots on top(in the future it will be in different languages )When I open the table, the text in the column is not readable.It converts the Turkish special character to some unreadable characters. Is there anyway to make the text readable in the table?

View 1 RepliesI am looking for the best way to edit and update the value of a database column that is defined as data type TEXT. You can't use a replace command in SQL and if I read in the value, update the data and update the record, the changes are not applied.
View 3 RepliesI've got a table in an SQL server that often has large amounts of data imported into it via an automated process - the problem is that a lot of the data that gets imported is a duplicate of data that is already in there (for example if we have a customer in there called Mr Customer Ltd, a duplicate with a slightly different name could get imported, like Mr.Customer Ltd).
So I am using the Fuzzy Logic class that Wild Bill put in the CodeBank to find names that are similar and then highlight these items. The thing is that the target table that the imported data ends up in has several thousand rows and the table that contains the data to be imported often contains several thousand rows as well, so I'm trying to decide how to do this. Obviously reading both tables into memory is not an option as it will consume too much memory on the client PC that is running this app. So this is what I am doing at the moment:
1. Read the table that contains data to be imported into a DataTable in memory
2. Open a connection to the target table and use the SQLDataReader to start to loop through it
3. In this loop, for each row that the data reader reads I then loop through the entire set of rows in the DataTable and run this fuzzy logic method that compares the account name from the current row in the datatable loop to the account name in the row that the datareader is currently on.(there is also a Thread.Sleep(1) after each row is processed to prevent the process from eating up 100% of the CPU while it runs)
i know that integer is a variable to store whole numbers and that a string is a varialbe used to store any text, but what variable type would you use to store a number that has decimals?
View 7 RepliesI'm doing a project where we are re-creating a very old system.The client wants the same base functionality and some improvements.One of the things I'm currently working on is the note-system. These are used as flags of some sort, but are also used as a comment field for some products or client profiles.In the old system you could write the text and save it like you would get in a .txt file. They want the new one to be able to do word formatting such as:
Different font sizes (Only some parts of the text)
Different font colours (Only some parts of the text)
Underlining of words
Bolding
Italics
Tab-spaces
Those are the specs they want. What I need to know is the following:
1) How do I do that?
2) Currently they store all these files on the server as text files and the database have paths that refers to each file. I want to be able to save a text file with that formatting to the HDD of the server like in the old system.
3) If possible I would like to save that text to the database with the formatting.
I am doing a small program in vb2005 with access database. In that I have a small issue, my database has 3 tables tblbill having vendorid & truckid to compare, tblvendor has vendorid & vendorname, tbltruck has truckid & truckno in these 3 tables i want to retrieve and show the vendorname based on the truckid based search. I have written code for some level and it doesn't work for me.
This is my code
Dim cmd1 As OleDb.OleDbCommand
cmd1 = New OleDb.OleDbCommand("Select tblVendor.VendorName, tblTruck.TruckID, tblbill.vendorid, tblbill.truckid " & _

I need comparing value from the same table for my final project.
Example :
Table 1 :
SubjectCodeClasses
Sub Aclass 1
Sub Aclass 2
Sub Aclass 3
Sub Bclass 2
Sub Bclass 3
Sub Bclass 4
Sub Bclass 5
Sub Cclass 6
Sub Cclass 7
Sub Cclass 8
...
My task is, I need to compare the classes in the subject. Sub A with class 1, class 2, class 3 have to compare with Sub B and Sub C. if classes from Sub A exist in Sub B then the output is 0, if not the output is 1. then Sub A again will compare with Sub C and the rest. After Sub A compare its value with other subject. Sub B will start comparing with all the subject and so on.
Below is the concept.
Sub ASub BSub C
Sub A001
Sub B000
Sub C100
I really don't know to do the loop..

View 4 RepliesMy application is in VS2008 coded in vb.net.I have a table with three columns FromDate,Todate and Schedule.FromDate and ToDate will have date values whereas Schedule will have a any of these values(weekly,Monthly,Yearly) In my Form i have given some provision to the user to check the records.
My requirement is The currentdate that is Today's date should be compared with the values of Fromdate and ToDate.First it should be check whether Schedule value is Weekly or Monthly or Yearly.If it is weekly than it should check the record in between fromDate to ToDate with a increment of one week.That means it should first check the first value of fromDate than add 7 days to the value and then again check from fromDate and this should continue till it reaches Todate.
