"Make Single Instance Application" Supposed To Work Across Multiple XP Users?
Jun 30, 2009I am writing a program in VB.net (vs 2008) that requires that only one instance of the executable be running at a time. Naturally I went for the simple solution by selecting the "Make single instance application" checkbox in the Project properties. Unfortunately, this option does not seem to work across multiple users that are logged into a single XP machine, thereby causing the same issues for my program as if I were able to run multiple instances on one single user. Granted this is a corner case, that someone would switch users while my program is running, but I'd like to understand the limitations. So my question is whether the "Make single instance application" property is supposed to work across multiple users? or is it limited to only one-instance-per-user.
Here are the steps the recreate the issue (prereqs: computer with XP pro installed, 2 user accounts (not on a Windows Domain), and a dummy "single instance" program created using the property mentioned above):
1) Log in with user1, start up the single instance program
2) Switch to user2 (StartMenu -> LogOff -> Switch User)
3) Start up the single instance program using user2
*After step 3, the program launches without complaint even though another instance is running on user1. Is this a glitch? or by design?
String Supposed To Find And Replace A Portion Of The Text And Write The Changes Back Out To The File Via Streamwriter
Jul 22, 2010I have thios code that will load a php file (text file) into a sting via streamreader then its supposed to find and replace a portion of the text and write the changes back out to the file via streamwriter. I put my code together and after running it look at the file and it's unchanged. After looking closer it appears the problem is the find & replace operation I am doing on the string. Here is my code:

Code Doesn't Go Where It's Supposed To?
Mar 2, 2010I have a VB.Net project that I haven't worked on in awhile. I got into this morning and started to run it. I got some errors so I decided to step thru the code. I enter the Page_Load event of a Form module and execute a function call and it takes me to a "End Function" statement. Totally bypasses the function that was called. I continued to step thru it and it just took me randomly thru code. No order whatsoever. I believe I've had this happen before but don't recall how I fixed it.

How Repeaters Are Supposed To Work
Jun 25, 2012I'm having lots of trouble understanding how repeaters are supposed to work and how I'm supposed to use them. Basically, I have a label, a set of image buttons, and a div within a repeater. When you click on the button, I want to populate the div that was created with these repeaters (so a different div for each iteration of the repeater).[code]I can't get the repeater to iterate. It's only firing off once and then stops. I can't get a label with the repeater data source's Subject (a field in my database) to appear.

View 2 RepliesCustom Button Is Showing Border When Not Supposed To?
Aug 25, 2008I was playing around with designing a custom interface for a test application and I am using a custom image for a close button. I am using the FlatStyle properties to define it's look'n'feel. I've set the border to 0 but when the application loses focus, the border of the button shows up.I have tried to force the property to go 0 again when the application's "LostFocus" event is captured but doesn't work.I am also using a "rollover" method using MouseHover and MouseLeave events to change the image of the button.Using Visual Basic 2008 Express Edition.

This is a part of a calculator code. When you press the button "BtnAdd" the text in TxtRes is held by the global variable "num1" and the operation number (whether add or subtract) by "oper". My problem is : OUTPUT 1: prints num1 = 25 (for example)While OUTPUT 2: prints num1=0
Why is this happening ? Isn't the value of num1 supposed to be equal everywhere in the form at a given moment ?
Supposed To Be Fullscreen In WPF Touchscreen Application Is Moving When Inner Listbox Is Scrolled?
Jun 30, 2010I am writing a GUI application to run on a touchscreen device using VB.NET and WPF--it must be full screen at all times, like a kiosk app; the window must not be able to resize or move in any way. The window contains a ListBox that users can currently scroll through by dragging across the list. The problem I'm seeing is that when the user drags across the list, the whole window moves a bit, exposing the desktop underneath, then springs back into place once the user stops dragging. I have not been able to figure out how to keep the window stationary while still allowing users to drag across the ListBox to view all list items. Here is a somewhat simplified version of my code:

View 5 RepliesMake Application 'single File' And Get Rid Of XML Config File?
Dec 29, 2010I have this pretty simple application, it uses a webService to transfer data to my servers DataBase. Now it is very important for me to keep this application as one single file, and not having some XML files needed for it to work, but this is the case. I think the XML file holds the information to this webService, so without it the application crashes. Is there a way to get the application to work without this XML file, or a way to put the XML inside the exe archive?
