VS 2008 EXE Loads Twice?
Oct 1, 2010
I have set up a scheduled task on startup in WINDOWS 7. This loads my app and displays information from .txt file sources. Mostly it functions correctly but occasionally loads the program twice or even three times thus creating errors trying to open files that are already in use. I seem to remember there is some way to load an .exe once only?

I have an app that connects to a remote database.The connection to the database is triggered by the form load event of the main start up form which prompts the user for user name and a password.Here is my problem:Sometimes it takes a number of seconds for the database connection to be established after the user has double clicked the desktop icon. this means that during this period it appears that no action is taking place until the startup form becomes visible.Some impatient users assume that nothing is happening and double click the icon again.What I want to do is to have a graphic image or something pop up on the screen immediately when the program starts that displays something like 'Connecting To Database, please be patient"

I am making a program that will fill in some info on a form. The information that needs to be filled is:
[Code]...
The thing is i need the program to click on a button on a website then open a new tab with the page it just clicked on, fill in email and click submit, then fill in the info that is above before pausing. I would also like the info above to be randomized each time the new page loads so it is not the same. I have already looked on this site and cant find what I am looking for.

Within the program, there is a button that opens a file inside of a second form ( DocViewFrm ) and it works fine the first time around. Within this new window, there is a button that uses Me.Close() to close the window and return to the main window. Upon the attempt to open this second form a second time, the program crashes on the Me.DocViewFrm.Show() line. The error message reads:
An unhandled exception of type 'System.ObjectDisposedException' occurred in System.Windows.Forms.dll
Additional information: Cannot access a disposed object.

I put a shockwave loader into my VB.Net application. When the shockwave loads, it opens about 20 different IE windows and says page cannot be found, while correctly loading the shockwave movie into the application. It's bizarre... how do I fix this? Not even sure if I should post this in this forum or a flash forum.

My application is runs without any external dependencies like .dlls. When I run my app, the controls flicker on as it loads. It's not terrible, but it's annoying and kind of takes down from the professionalism. I was trying to figure out what was causing it and found out that it was my background image. My background image is a jpeg and I guess it is too large. Is there a way I can get it to load the image better so my controls don't flicker or maybe use a different file type that is smaller?

I want to be able to make labels on the form change with user-entered variables (that they would do before this form appears) and so when this form appears, I want the variables to already be displayed in the labels without them having to press a button, or click on something.

So in this program that I've made, I have 5 tabs. One of them uses this chart control for .NET ver 3.5 that I downloaded from the Microsoft website. The issue is, though, that when I start the program, everything is fine until I click on the tab with the 3 charts on it. The tab freezes a little bit, and it takes a few seconds to load the charts. After this initial hiccup everything is fine, but I've tested this on three computers now and it happens to all of them. Anyone know what I can do to make these charts load faster or smoother? This is quite a roadblock.because otherwise I'd be done I've been working on this project in VB.NET for the past 3 weeks and it's my first time using the language. So far every single one of my questions on here has been answered and all within a day or two

I wrote this application in VB2008 and it ran for three years without problems(It had one first chance error during that time but ran correctly). I started having problems at the first of this year with a textbox not showing the update for the date code correctly. So I thought that maybe some update to the system had changed and I might need to do some code changes to take into account for these updates.I first tried to convert it to 2010 but the conversion would not operate correctly even though the code showed to be correct.It would jump from one form to another in the middle of a if statement using debug to step through the code. the if statement would just test for a variable to be less than 2 and then be changing the text in a textbox. So I decided that It would take longer to correct the converted application then to just use VB2008.
So I went back to VB2008 and my XP to find out why the date code had quit working. This code had been working correctly for three years.I was thinking some of the code used had become outdated in some way, because a copy of the original source would not run in debug mode correctly. It showed the same problem of not updating the textbox. I stepped through debug and found that it was doing the same thing as the VB2010 version and jumping in the middle of the if statment. So I rewrote the code and used the format string command to build the date code in stead of the seerating out the date into 3 variables using a split statment.This works for the textbox problem and stoped the jumping to a different form. But since I have went back to the original code I have the first chance errors comming up.
I have several first chance exceptions being thrown from debug. This happens when I fisrt start the debug and I have put break points all through the applicatins to try and find the problem I have also enabled debug exceptions Common runtime thrown and it still gives the exceptions but no break point.I have option Strict on. There is no errors or warnings showing after a build. I have cleaned the solution and exausted all my methods of troubleshoooting this problem.The following is what I am recieving while in debug mode in the immediate window.
A first chance exception of type 'System.IndexOutOfRangeException' occurred in LABEL MAKER 2 Forms.exe
A first chance exception of type 'System.IndexOutOfRangeException' occurred in LABEL MAKER 2 Forms.exe
A first chance exception of type 'System.IndexOutOfRangeException' occurred in LABEL MAKER 2 Forms.exe
A first chance exception of type 'System.IndexOutOfRangeException' occurred in LABEL MAKER 2 Forms.exe
A first chance exception of type 'System.InvalidCastException' occurred in Microsoft.VisualBasic.dll
A first chance exception of type 'System.InvalidCastException' occurred in Microsoft.VisualBasic.dll
Now if I run this as a published application I get the same error as the first one on the above list and it gives a error window with continue, exit,and details, if continue is pressed it will allow me to continue and the application runs correctly.The details just say basicly the same as the error with no error number and that the error was in my application.exe. Nethier of these errors will give a break point so that I can find the problem. The problem does not appear to be in my code because this happens before the first form appears.

I have a vb.net project in vs2008. When the project loads, one form is always immediately marked as changed before anything has been done to it. This didn't happen in earlier versions of the form. Nor does it happen with any other forms, classes, modules, etc. I have no idea why it is occurring but I am curious.

is what I have so far. I have a form that needs to load a file externally and populate the combobox. I can get that part if I use a button, but I don't want to use a button. I want it to populate when the form loads for the first time. The below code does not accomplish this, it doesn't even try to load it. I put break points in this code but it never breaks
