I have a problem loading my data to my database. I am using mysql. I noticed the problem when i executed my code and it kept giving me a "Argument 'Prompt' cannot be converted to type 'String'" error. But when i checked the db it had some the information in there it would not have the last 3 or 4 data entries in the db. I went back to check the string that was providing the command and I saw that the program was running most of the commands correctly however close to the bottom of the script it was cutting the command off and so the db could process the rest of the information. Can anyone tell me why the data is getting cut off. here is my code it is for a winform app. :confused:
VB.NET:

Imports MySql.Data.MySqlClient

Imports System.IO

        InitializeComponent()

        'Add any initialization after the InitializeComponent() call

    End Sub

    'Form overrides dispose to clean up the component list.

Not sure but do notice something

I did notice that the file that you are reading is comma delimited however when you are comma delimitting something you should also qualify it. It could be possible that this data is getting split and messed up for that reason. It is good habbit to qualify comma delimited text files with quotations. That is why when I am creating index files I like to use a | (pipe) or a ~ (tilde) because it does not leave room for error when splitting comma delimited files which i find myself doing often in the work place.

This is code that may be useful to test if all the data in the text file is good or not. Just place the file path in constructor for the streamreader. This will test that when split at the commas that all fields will have equal values this is a good test for comma delimited files that are not qualified with quotations.


p.s.

I just wrote it up so tell me if you thought it was useful or not because I am trying to get involved on these forums because it helps me learn because I am just beginning to finsih my degree in programming up in about 18 mo's online and plan to get for MCSD/MCAD type certification.

Sincerely,

sorry for taking so long ss7. I believe the program is reading the text file properly. it is when it goes to the qry variable to create the command string it is cutting off there. Still haven't figured out what's the problem though.

Another Suggestion

Check the values that are being passed in that ArrayList I am not too familiar with this object but it seemed like something funky was going on there with the join statement I did not get a chance to run the code because I am at work but the first thing that I would do to determine what was wrong would be to print out that dbf variable to check that you are passing it valid data and because it seemed like that join may have been causing you to pass to many values but if not another suggestion would be to check the syntax of the SQL statement because you are supposed to have single quotations around stuff in MySQL but not sure if that matters because a lot of programmers set it up to add that stuff outside that code so try these things out and ill try to run it if you are still having trouble.....

I am still trying to figure out why the program is cutting the qry variable string. that is the problem i found. I sent the qry variable's output to a text file and it will run all of the text strings i specify in a loop except the last 3 or 4 lines. for example let's say qry is equal to: ->"This is a test of the emergency broadcast system". <-:

In my program if i looped this statement let's say 18 times it would print out the statement about 16 times and then cut the next line and not even show the 18th line like this
16: this is a test of the emergency broadcast system
17: this is a test of the
18:

this the reason the mysql is throwing the error because it is not getting a full command. I am trying to figure out why my program is cutting the lines off. thanks for any help you can give ss7 i really do appreciate it.
Help from anyone would be appreciated.

Try something else....

Maybe you should try another type of variable rather than an array list that seems like an older command try comething like a collection or maybe just a good old string and accumulate the text kind of like you are doing. If you want I always this string collection class that I wrote try it out instead of the array list because i think that may be what is causing your problem.


Public Class StringCollection
Inherits CollectionBase
Default Property item(ByVal index As Integer) As String
Get
Return CType(InnerList.Item(index), String)
End Get
Set(ByVal Value As String)
InnerList.Item(index) = Value
End Set
End Property
Sub Add(ByVal Value As String)
InnerList.Add(Value)
End Sub
Public Function IsInternedWith(ByVal strValue As String) As Boolean
Dim blResult As Boolean = False
For Each str As String In Me
If str.ToUpper = strValue.ToUpper Then
blResult = True
End If
Next
Return blResult
End Function
Public Function ToStringEachItemToLine() As String
Dim strReturn As String = ""
For Each str As String In Me
strReturn &= str & ControlChars.CrLf
Next
Return strReturn
End Function
Public Sub New()
End Sub
End Class

I just find this easier to use even if you are going to try to have an array of StringCollections but this is just better than arrays in my opinion and I can easily whip one up for each data type and write various functions for it. Even if this doesn't work for this program it may be useful elsewhere.
