It runs when your ASP.NET app spins up for the first time.

Not quite sure what that means.... example, in my code I updated a db field that was placed in a word document, then I have the sub application_start send it email.
I did that earlier today but have not received the email back yet, so I was wondering if I have to write code that causes the sub application_start to start?

No, but unless you restart IIS, this code won't run. It gets run when IIS starts.

hmm, so How do I get it to work to send out email without restarting IIS, That seems strange? If I want the email to go out daily, do I need to have a trigger or something to restart IIS all the time?
|
|
|
|
|
No need to restart IIS daily for purpose of sending mail .Restarting IIS means restarting application .
If you want to automatically send email daily , then create a small exe In which can be scheduled to run once in a day .This exe can be created in vb / vb.net .

My application is going to move some files when a button is clicked.
If the file is opened by other application,
my system.io.file.move(file) will have exception,
How can I detect the file is opened by other application before the move action?
Thanks.

Catch the exception.

I know this method, but any other way?

Catching the Exception is the only way to get feedback that a file is open and can not be moved...
What you need to do is loop throuhg the files you are moving and when it hits a locked file it keeps trying till it can.
<br />
Dim bIOEx As Boolean = True<br />
Try<br />
If blnMove = True Then<br />
Do<br />
Try<br />
System.IO.File.Move(strOriginalFile, strDestinationFile)<br />
bIOEx = False<br />
<br />
Catch ex As IOException<br />
bIOEx = True<br />
End Try<br />
Loop Until bIOEx = False<br />
End If<br />
Catch ex As Exception<br />
MessageBox.Show("The File Redirection Failed" & vbCrLf & ex.Message, "Move Error", MessageBoxButtons.OK, MessageBoxIcon.Warning)<br />
Finally<br />
blnMove = False<br />
End Try<br />
You may want to do a loop count that times out after 3 tries 10 seconds apart.
Hope this helps...

I am new at vb.net and would like to know
What object is streamwriter located under?
Is it a function or sub routine?
VS 2003:
I have a project with the folowing in code behind:
Dim sw As StreamWriter
I thought maybe I could drill down in the objects and find it.
I assume that is under System.IO?
I did an Ctrl ALT J in visual studio to look at the classes
and I cannot drill down to streamWriter?
Where can I find where streamwriter is located?
|
|
|
|
|
|
I was trying to drill down to it in visual studio but It does not drill down very far in system.io for visual studio.
Unless I am doing something wrong?

Do you have "system" referenced in the solution explorer?

I have written a very simple vb.net app to look at some properties in an msi file. Whenever I execute the msiInstall = CreateObject("WindowsInstaller.Installer") statement I get the error: Cannot create ActiveX component. I have added a reference to the Microsoft Windows Installer module and msi.dll is definately registered on my system. I have declared the msi object using Dim msiInstall As WindowsInstaller.Installer.
When I run the same bit of code in VBScript I do not get this error so it must be something in my VS 2003 configuration.
This is the complete error with details when I compile and run the exe:

Hi,
i want to create a multiple datasets and bind it seperately. the query will look like
select * from table where id=ID
now,
if id = 1,
i want to generate dataset1 just for records with id=1 and
if id = 2,
i want to generate dataset2 just for records with id=2 and so forth

no problem dude.
just create 2 query n store them in 2 seperate variable.
say
Dim q1 As String="SELECT * from table WHERE id=2"
Dim q2 As String="SELECT * from table WHERE id=2"
Dim cmd1 As New SQLCommand(q1,conn) 'conn is ur connection
Dim cmd2 As New SQLCommand(q2,conn)
Dim da1 as New SQLDataAdapter
Dim da2 as New SQLDataAdapter
da1.selectCommand=cmd1
da2.selectCommand=cmd2
Dim ds1 As New DataSet
Dim ds2 As New DataSet
da1.Fill(ds1)
da2.Fill(ds2)
' ur dataset populated
' show them
DataGrid1.DataSource=ds1
DataGrid2.DataSource=ds2
Hope that helps.
this is not the end, this is how its goin to begin !

I am creating a simple form that requires additional information before being displayed.
What I want to do:
Override ShowDialog(owner) with ShowDialog(owner, string0, string1) As DialogResult
That part is easy.
What I want to do is prevent the use of ShowDialog() and ShowDialog(owner).
Naturally, there are many ways to accomplish what I am trying to do, but I really want to know If I can do this. Is there a way to override these methods (or some other way) so that thay may not be called on my custom dialog?
Thanks

Guess I didn't pound my keyboard long enough. Kept looking and I found it. Use "shadows" instead of "overrides" and it does exactly what I wanted.

I use DB2 under AS/400 and the “SLTFORMULARIO_MG” stored procedure really exists.
Ok... because we don’t have that much time to spend, I tried another solution. I did remove the link between the stored procedure and the RPT file and so, I did set up one xml datasouce. So, I putted the stored procedure returns into a dataset and did use as:
<br />
oRpt = New ReportDocument<br />
oRpt.Load(_sFileRPT)<br />
<br />
oRpt.SetDataSource(_dtDados)<br />
Ok, the code ran nice and quickly, but because I can go to heave straightway. I still have a problem when using formulae to perform calculation. I got this damn error:
MENSAGEM DE ERRO:
A number, or currency amount is required here.
Error in File C:\DOCUME~1\BRRIOW~1\ASPNET\LOCALS~1\Temp\PEDIDO_SA {8885AC00-192E-4A1D-9E2A-A38289AEA818}.rpt:
Error in formula <UNITxVALOR>.
' ({SLTFORMULARIO_SA.PRECO_UNIT}) * {SLTFORMULARIO_SA.QTD_PEDIDA} '
A number, or currency amount is required here.
STACK TRACE:
at CrystalDecisions.ReportAppServer.Controllers.ReportSourceClass.Export(ExportOptions pExportOptions, RequestContext pRequestContext)
at CrystalDecisions.ReportSource.EromReportSourceBase.ExportToStream(ExportRequestContext reqContext)
Right, Right, I did many tests and when I changed the code from:
({SLTFORMULARIO_SA.PRECO_UNIT}) * {SLTFORMULARIO_SA.QTD_PEDIDA}
To:
({SLTFORMULARIO_SA.PRECO_UNIT}) + {SLTFORMULARIO_SA.QTD_PEDIDA}
It was fine, except from the fact that it was catenated instead of added.
Anyone could, please, help me up?

I am attempting for the first time to link Crystal reports with VB.Net and having a wee bit of trouble. I have provided some code I have done but for some reason it is not recognising....
Dim cr As New ReportDocument
What reference have I missed out and what is the best way to do such a thing. Any help, ideas would be gratefully appreciated.
Dim DA As OleDb.OleDbDataAdapter
Dim DS As New DataSet
Dim strSQL As String
strSQL = ""
strSQL = "SELECT EmployeeID, LastName, FirstName FROM EMPLOYEES"
DA.Fill(DS, "Employees")
'Verify the path to the Crystal Report's .RPT file
Dim strReportPath As String = "C:\Temp\crystalreport1.rpt"
'Load the Crystal report's .rpt file and pass in the data table
Dim cr As New ReportDocument
cr.Load(strReportPath)
cr.Setdatasources(DS.Tables("Employees")
