At the time of error str has value 'SheetName'!RangeName (This is fine.. )

I have created a query method for my tableAdapter in the dataset designer. I typed the command text manually, but tested it in the query builder after I got a Constraint Exception when debugging. When running in the query builder via 'Execute Query' I get exactly the results I expect. When running the application I get this exception: "Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints." I tried temporarily setting my dataset's EnforceConstraints property to FALSE but still get the same exception. I can't understand why the Query Builder would return the correct datatable but running the app would not. Is this a bug?

I don't think the problem lies within the codes but..The last thing I did was use datediff.. and show the result on a label.. and when I wasn't satisfied with the result I changed a few lines, and I noticed it was still the same whenever I run it.I've tried changing/deleting the codes to my forms but whenever I run the program, it still works. I even tried deleting the form and it still works.

I'm attempting to create an app which uses a vendor-supplied Web Service. They provided sample code to show how to work with the Web Service, but all the code is in C#.. not a huge deal.I opened one of their demo projects and it compiles fine, works perfectly.
So, I open up MY project, drop in the converted code and... wait for it... ERROR!Here is the working C# code that IS working:
C#
private void DoSomethingWithTheAlarm(G4T.enAlarmAction action) { XML_AlarmClearRequest[] ClearRequest = new XML_AlarmClearRequest[lstAlarms.SelectedItems.Count]; int idx = 0; foreach (ListViewItem lvItem in lstAlarms.SelectedItems) { ClearRequest[idx] = new XML_AlarmClearRequest();

I have a program that uses the mouse to find window captions. I made a test program that just does that and it works fine. I copied and pasted the code into my other program and it doesn't work. The mouse position changes, but it will only get the caption of a window if it is at the top of the screen. It seems that only the Mouse.X position is changing, but I put the MousePosition.X and Y in a label and they are both changing. Can anyone explain why this is happening?

In my project, I have a local dataset (XSD) that I am using as local-temporary tables. I am getting a System.InvalidCastException when trying to access the field in one the tables. I believe this is because I my code is (incorrectly) not setting a field's value in a row before trying to access it.My problem is that the exception is breaking in the designer file and not in my code. As a result, I'm having difficulting determining which line of my code reading the field value before it has been set. Is there any way to configure Visual Studio to break in my code instead of in the designer created file?

I have some code below that works mostly in vb.net but when it gets to ExtHubPort and after it doesnt work i think i might have incorrect formatting of code somewhere or a simple error because if I get it the same sounds as the vbscript except when mouse device is plugged in it gives me this error in device manager: "device could not start error 10". Here is the code but to plainly put it the code just adds an emulated external usb hub to the system's hub and then usb device to that hub:
Option Explicit On
Imports System
Imports Microsoft.Dsf
Module Test_Emulator

The msgbox's mark important areas that will help if you wish to debug this code. I have a codeplex page in which the project has the dlls for both 32-bit and 64-bit OS's but if you have the dsf runtime you can manually get them from the GAC (c:windowsassembly version and yes im sure because thats where i found them) and just paste into visual studios public assmeblies folder and it

Puzzled why the same Sub Page_Load code will not work if used on the codebehind file. Current code works fine if used directly on the aspx page,but as soon as i try placing the same code in a codebehind file the images will not show at all. Will post code sample if requested.. The way the code is setup thumbnail page opens a new page that displays larger image with watermark. the watermark page only contains code that creates the watermark for the larger image page.

I have a simple unit test which tests that a validation function picks up a specific validation issue. The validation item returns a simple object with Item & Message properties. I've written a unit test for this function but this always fails even though I know the function works as expected.
<TestMethod()> Public Sub ContractNote_ValidateForManualInputTest_TradeOrderValueComparison()
'Can't get this test to work even though validation works!
Dim CN As ContractNote = New ContractNote
Dim Trade As New TradeOrder
[code].....
I've implemented IComparable on ValidationItem (I have a separate unit test which confirms this works). Am I Using CollectionAssert correctly?

I have a small problem, I have written a small application to update a database table. Now on my computer I have a copy of the database but using MSDE 2000 and when I run my application it works perfectly, however I also have a copy of the database attached to MS SQL 2005 on another computer. Now when I got an run my application on this machine, it fails with a "Time out" error. I have changed the timeout settings on the SQL Server however it then just sits there for ages, whereas when I run it on my development machine MSDE 2000 it loops through the code quickly.

I have developed an ASP.Net 2.0 application and I am facing problem in sending email from my Web Server. Following is the VB code I have used to send email from my web application. Thing is when I try to send email from my local system (laptop) the email goes out fine and reaches the recipient address instantly but when I try to send email from my web server it fails.My hosting provider gave me a relay-host address for sending out email. The email goes out fine but the relay host has an annoying amount of delay in email delivery which is a problem during the sign up process.
Here is the code I am using:I have imported system.net.mail in my code and used async="true" on the aspx page.
Private Sub SendMail(ByVal actcd As String)
Dim mailMessage As New System.Net.Mail.MailMessage
mailMessage.From = New MailAddress(support@ihomejobs.com)
[code]....
I have tried the above settings and they work fine from outlook and the application when tried on my laptop but these settings fail on web server.I want to send email from my web server without using a relay-host.

I have written a console app in <acronym title="Visual Basic">vb</acronym> .net 2003 to capture audio data (albeit not for an audio application) using the WinMM API. This works well in XP and also on my own Vista PC. However when others try to use in on Vista or Win7 it stops working after about 10 - 30 seconds (so it manages to initiate recording from the default input device but eventually stops). The only error given is "Program has stopped working". I am wondering if this is related to the way I recycle the input buffers?

I have a situation that has puzzled me for weeks. I am running logic that does a bit of back and forth to and from the database for each time it is executed (about 20 times). The problem is that the same code works about half of the time. What could possibly be the reason for the difference in execution performance and how can I better shore that this problem is checked?

The vb.net code is functioning correctly as it talks to a device through COM1 serial port.What I was hoping was the equivalent c# code is not creating the same string and as a result, the serial 'packet' is not correct. Check this illustration of my problem [URL]...
My goal is to eliminate the addition of the extra characters '/0' and '/b' that what I hoped was the c# equivalent to the correctly functioning vb.net code. It just occurred to me I should change the code to employ Stringbuilder. The 'packetbuilder' method/function builds a string and keeps concatenating things to itself.
