  • Program ends abruptly even in debugger - how did that happen?

    - by Mick
    I am trying to debug a program that unexpectedly shuts down. When I say "shuts down, I mean one moment I am seeing all the windows being displayed, each of which is showing all the right data,then suddenly all the windows disappear. The is no messagebox reporting anything wrong. So I tried running the program in the debugger hoping that it would somehow trap whatever was causing the program to abort, but even within the debugger the program simply ends abruptly. The last line in the debugger is: The program '[5500] test.exe: Native' has exited with code 0 (0x0). My program which is extremely large and extremely old has a lot of self diagnostics. My suspicion is that perhaps a self test has failed and maybe I just called "exit()", forgetting to pop up a dialog explaining why. My question now is, how can I find out from which point in the code, my program quit?

  • How many records can i store in a Sql server table before it's getting ugly?

    - by Michel
    Hi, i've been asked to do some performance tests for a new system. It is only just running with a few client, but as they expect to grow, these are the numbers i work with for my test: 200 clients, 4 years of data, and the data changes per.... 5 minutes. So for every 5 minutes for every client there is 1 record. That means 365*24*12 = 105.000 records per client per year, that means 80 milion records for my test. It has one FK to another table, one PK (uniqueidentifier) and one index on the clientID. Is this something SqlServer laughs about because it isn't scaring him, is this getting too much for one quad core 8 GB machine, is this on the edge, or..... Has anybody had any experience with these kind of numbers?

  • Changing MSSQL Database sorting

    - by plaisthos
    I have a request to change the collation of a MS SQL Database: ALTER DATABASE solarwind95 collate SQL_Latin1_General_CP1_CI_AS but I get this strange error: Meldung 5075, Ebene 16, Status 1, Zeile 1 Das 'Spalte'-Objekt 'CustomPollerAssignment.PollerID' ist von 'Datenbanksortierung' abhängig. Die Datenbanksortierung kann nicht geändert werden, wenn ein schemagebundenes Objekt von ihr abhängig ist. Entfernen Sie die Anhängigkeiten der Datenbanksortierung, und wiederholen Sie den Vorgang. Sorry for the german errror message. I do not know how to switch the language to english, but here is a translation: Translation: Message 5075, Layer 16, Status 1, Row 1 The 'column' object 'CustomPollerAssignment.PollerID' depends on 'Database sorting. The database sorting cannot be changed if a schema bound object depends on it. Remove the dependency of the database sortieren and retry. I got a ton more of the errors like that.

  • button of MDImenu can't disenable in VS2008

    - by colorlee
    Hi everyone. i had just started to learn VB and VS2008 and im doing some system due to my homework. i made a WELCOME form with a timer, 5s to pass to the next form which called Select. After passed to next form, itll me.visible = false. Theres 3 buttons on the Select form which call Customer, Staff and Exit. As i had just start, the button Customer will pass to a MDI menu call Customer Menu with a menu strip button called Quotation. Same, Select will me.visible = false when done. Then a problem occured, i made a Quotation inside the Customer Menu, such as the mdiparent of Quotation is Customer. I expected that the Quotation button will disenable to press after i pressed that button. But i fail to do that. And the code below: This is the code of MDI menu Customer Menu: Public Class frmCustomer Private Sub ExitToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ExitToolStripMenuItem.Click End End Sub Private Sub AboutUsToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AboutUsToolStripMenuItem.Click Dim frm As New AboutMamatai AboutMamatai.ShowDialog() End Sub Private Sub frmCustomer_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load frmQuotation.MdiParent = Me frmQuotation.Show() frmQuotation.Dock = DockStyle.Fill Me.Location = New Point(220, 180) End Sub Private Sub QuotationToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles QuotationToolStripMenuItem.Click frmQuotation.MdiParent = Me frmQuotation.Show() frmQuotation.Dock = DockStyle.Fill End Sub End Class This is the code of the form inside the Customer menu: Public Class frmQuotation Private Sub btnExit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExit.Click frmCustomer.QuotationToolStripMenuItem.Enabled = True Me.Close() End Sub Private Sub frmQuotation_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load frmCustomer.QuotationToolStripMenuItem.Enabled = False End Sub End Class When im tryin to solve this problem, i found that the problem may cause of the me.visible = false of the Select form and Welcome form. Becoz when i set the Customer Menu be the first form to run. The problem is not exist. Is there anyone can help me ? P.S. I guess if the other two forms code is needed so i post them also This is the code of WELCOME form : Public Class frmWELCOME Private Sub frmWELCOME_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Me.Location = New Point(270, 210) Timer1.Enabled = True End Sub Private Sub Timer1_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles Timer1.Tick Timer1.Enabled = False Dim frm As New frmSelect frm.Show() Me.Visible = False End Sub Private Sub btnSkip_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSkip.Click Timer1.Enabled = False Dim frm As New frmSelect frm.Show() Me.Visible = False End Sub End Class This is the code of Select Form: Public Class frmSelect Private Sub btnCustomer_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCustomer.Click Dim frm As New frmCustomer frm.Show() Me.Visible = False End Sub Private Sub btnStaff_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStaff.Click Dim frm As New frmStaff frm.Show() Me.Visible = False End Sub Private Sub btnExit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExit.Click End End Sub Private Sub frmSelect_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Me.Location = New Point(390, 250) End Sub End Class

  • How can I get "Copy to Output Directory" to work with Unit Tests?

    - by spoon16
    When I build a unit test project before the tests are executed the test output is copied to a TestResults folder and then the tests are executed. The issue I'm having is that not all the files in the Debug/bin directory are copied to the TestResults project. How can I get a file that is copied to the Debug/bin directory to also be copied to the TestResults folder? EDIT: Here is a link to a similar question on another site (no answer there though), http://www.eggheadcafe.com/software/aspnet/29316967/files-and-unit-testing-wi.aspx

  • how to use a parameterized function for the Default Binding of a Sql Server column

    - by Walt Gaber
    I have a table that catalogs selected files from multiple sources. I want to record whether a file is a duplicate of a previously cataloged file at the time the new file is cataloged. I have a column in my table (“primary_duplicate”) to record each entry as ‘P’ (primary) or ‘D’ (duplicate). I would like to provide a Default Binding for this column that would check for other occurrences of this file (i.e. name, length, timestamp) at the time the new file is being recorded. I have created a function that performs this check (see “GetPrimaryDuplicate” below). But I don’t know how to bind this function which requires three parameters to the table’s “primary_duplicate” column as its Default Binding. I would like to avoid using a trigger. I currently have a stored procedure used to insert new records that performs this check. But I would like to ensure that the flag is set correctly if an insert is performed outside of this stored procedure. How can I call this function with values from the row that is being inserted? USE [MyDatabase] GO SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE TABLE [dbo].[FileCatalog]( [id] [uniqueidentifier] NOT NULL, [catalog_timestamp] [datetime] NOT NULL, [primary_duplicate] nchar NOT NULL, [name] nvarchar NULL, [length] [bigint] NULL, [timestamp] [datetime] NULL ) ON [PRIMARY] GO ALTER TABLE [dbo].[FileCatalog] ADD CONSTRAINT [DF_FileCatalog_id] DEFAULT (newid()) FOR [id] GO ALTER TABLE [dbo].[FileCatalog] ADD CONSTRAINT [DF_FileCatalog_catalog_timestamp] DEFAULT (getdate()) FOR [catalog_timestamp] GO ALTER TABLE [dbo].[FileCatalog] ADD CONSTRAINT [DF_FileCatalog_primary_duplicate] DEFAULT (N'GetPrimaryDuplicate(name, length, timestamp)') FOR [primary_duplicate] GO USE [MyDatabase] GO SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE FUNCTION [dbo].[GetPrimaryDuplicate] ( @name nvarchar(255), @length bigint, @timestamp datetime ) RETURNS nchar(1) AS BEGIN DECLARE @c int SELECT @c = COUNT(*) FROM FileCatalog WHERE name=@name and length=@length and timestamp=@timestamp and primary_duplicate = 'P' IF @c > 0 RETURN 'D' -- Duplicate RETURN 'P' -- Primary END GO

  • Creating an appropriate index for a frequently used query in SQL Server

    - by Slauma
    In my application I have two queries which will be quite frequently used. The Where clauses of these queries are the following: WHERE FieldA = @P1 AND (FieldB = @P2 OR FieldC = @P2) and WHERE FieldA = @P1 AND FieldB = @P2 P1 and P2 are parameters entered in the UI or coming from external datasources. FieldA is an int and highly on-unique, means: only two, three, four different values in a table with say 20000 rows FieldB is a varchar(20) and is "almost" unique, there will be only very few rows where FieldB might have the same value FieldC is a varchar(15) and also highly distinct, but not as much as FieldB FieldA and FieldB together are unique (but do not form my primary key, which is a simple auto-incrementing identity column with a clustered index) I'm wondering now what's the best way to define an index to speed up specifically these two queries. Shall I define one index with... FieldB (or better FieldC here?) FieldC (or better FieldB here?) FieldA ... or better two indices: FieldB FieldA and FieldC FieldA Or are there even other and better options? What's the best way and why? Thank you for suggestions in advance!
