I have a ListBox on a Windows Form which is bound to a property of an object. The object's property is a list of messages, defined as List<string>. In code I have updated the object and its list of messages, but the list displayed in the ListBox has not changed. I can force the list to update...

I have a C# application that needs to call an external application. When I hard code the path to the external application, it works fine. However, I would like the path to the external application to come from a settings file instead. I have stored the path as a string in a Settings.settings...

I am designing a form for an application in C# 2005 which receives input from a USB barcode scanner (which seems to treat the data as if it had been entered from the keyboard--without the usual key down/up/press events, of course). I would like to be able to allow the user to scan multiple...

I am experiencing problems trying to use a reponed connection to the database. We use a VB6 front end, and a SQL Server 2000 database using ADO connections from Windows 2000 PCs (via application role access). We scan boxes of product as they pass down a conveyor to update the inventory. I was...

I am running XP Pro on a FAT32 30GB Western Digital hard drive in an AMD 1.1GHz machine with 768MB RAM. I want to move it to an 80GB Western Digital drive in the same machine. I have attempted the move using Power Quest Drive Image (both 2002 and 7). I get wierd results. The 80GB hard drive...

Last night I ran into an interesting situation. A client's computer (running Windows XP Home) would not recognize the keyboard and would not boot. It gave the error indicated (I don't remember the exact wording, but what I wrote is close). It wouldn't boot from the hard drive and it didn't...

I am working on a project (VB6) that is set to create an ActiveX EXE. It doesn't appear as an application on the TaskBar (not the System Tray). This makes it difficult to switch between tasks. Can ActiveX EXEs appear on the TaskBar like Standard EXEs? If so, what am I missing? Thanks (in...

I have an application in VB6 that is an ActiveX.exe which launches a .bas module when it runs. No button is displayed in the taskbar while the application is running. It doesn't appear when you use ALT-Tab to switch among open applications. When you minimize it, a button appears just above...

I need to be able to hide (.Visible = False) selected menu options on a VB form at runtime. I am able to do so (using the Controls collection), with one exception. If I attempt to hide the last visible item on a menu, VB returns an Error 387 because you can't have a menu with no items on it...
