• thomas woelfer BackgroundWorker vs Try/Catch?

  Hi. I have an app that spawns a couple of BackgroundWorkers. The process works perfectly when all the target servers are available. For testing purposes, I added some non-existant servers to the mix. The problem is in the Try/Catch block of the background process. I have to connect to a SQL Server first, then do stuff. Even though I handle the problem to gracefully exit, I keep getting the message in Debug mode. TargetInvocationException was unhandled - Exception has been thrown by the target of an invocation. -InnerException.Message: {"Object reference not set to an instance of an object."} I thought maybe this was a noob question similar to VB6's option "Break on all errors/Break on unhandled errors," b ...Show All

• RizwanSharp Copying structures

  Hi, I have the situation where I need to pass a structure to a dll where it's manipulated and then passed back. Unfortunately the passed structure can't be used during the manipulation stage and so I was wondering how I could take a temporary copy of the structure when entering a dll, do the manipulation on that and then overlay the original structure with the temporary structure when I'm finished. Thanks for any help. In order to copy a whole structure, it is enough to use the "=" statement. This really clones the structure. For instance: void MyMethod( ref MyStruct s ) { MyStruct tempCopy = s; ... do something ... s = tempCopy; } Sorry if I use C# syntax instead ...Show All

• Demix Missing last record - ADODB Recordset

  Here are the essentials: * Really simple setup * MS Access 2003 db 1 MS Access query getting records from 1 table in the db table has 10 records -- the query correctly returns 5 records based on WHERE clause VB code to create ADODB recordset using the MS Access query VB code or compiled .exe and MS Access db are on the same computer The problem: When the VB code runs, the recordset is created and returns only 4 records when 5 is expected.

• gshaf Multithreading in classes

  Hi, I'm writing a class that sends data via a TcpClient, and also listens for responses from the server using the same TcpClient. I'm using methods to send the data, and fire events when data comes in from the server. It's these events that's giving me problems. I used System.Timers.Timer to check if there's any data available from the server and if there is, I parse these and fire the relevant event. I've created several classes that inherits from the EventArgs class to hold the information. The correct args are passed into the event. Something like: Public Event OnConnect( ByVal sender As Object , ByVal e As ConnectEventArgs) Now, the way I understand it is that the timer runs in it's own thread. This causes the custom eve ...Show All

• systech Illeagal Characters In Path Error.

  Hi, I have this error, Illeagal characters In path. I figured out it happend when the FILE NAME had spaces in it, so It took me one week to make it change the spaces to "_". In the debug I didn't have the problem any more. Now I installed the program, and it happend. I don't know the exact line, but if it's because of space it's in the Folder's name. SPACE ISN'T AN ILLEAGAL CHARACTER! Why does it happen Is it a bug in VS How can I fix it Thanks. I wouldnt have though it was simply because the path contained a space as these folders look like they are generated - perhaps as a result of a click once deployment.
