The application works fine on Vista but throws this error on Windows 7:
- The type initializer threw an exception.
This is the code that causes it:
Public UserName As String = String.Empty
UserName = Environment.UserName

I'm using VS 2005 and have managed to get my application to run fairly robustly. Now it is time to deploy it and let the rest of the group use it.
File
Add
New Project
Setup & Deployment
Setup Wizard
I double click Setup Wizard and I get: "Catastrophic failure (exception from HRESULT: 0x8000FFFF (E_UNEXPCTED)" I've googled a lot of references and read through them but none of them seem to be applicable to my case.

I can hide my startup form (or make it appear hidden) on startup. I can start my app on windows startup--through registry values--if the user checks a checkbox.
But if the app starts up on windows startup, I want the form to be hidden, so the program can just keep working without bothering anyone. If it starts up because the user started it, I want the form to be showing, because the user probably wants to change some settings or something.

I'm having an odd problem with an ASP.Net page.I'm getting an object not set error message when assigning a string literal to a variable. [code] And here is the code that the error is pointing to. The last line in this fragment is the line 10 the error is complaining about [code] It seems it fails on accessing any reference type, even if it is declared locally in the load function. I originally found the problem when Request. IsSecureConnection was nulling out on me. I eventually discovered I could replace it with the above code and fail in the same way. The problem does not always happen. It seems to be triggered by publishing an update from Visual Studio, or when I head home for the day and the server sits idle all night. One or two app pool recycles seems to clear it up, and the page functions correctly. I've been doing desktop development for a few years, but I'm fairly new to web development.So maybe this is something obvious I've got configured wrong. I'm currently using .Net 4 on IIS 6. That code is in a foreach over an IEnumerable(of XElement). The stack trace still points to the string assignment, but all other stack traces are spot on, so I don't think it's a bad pdb.Also, when the error occurred this time, no amount of recycling the app pool or stopping and starting it would fix the error. I finally got it working again by switching the application to a different app pool.

I have 2 tables which I want to insert data into, table "CAM" and table "COut", after inserting data in "CAM" it shall return a retAutoID which will be hand to "COut" as one of the parameter required for it's insertion. I implemented a rollback in my Business Logic such that if "Cout" hits an exception error while inserting, the previous insertion for "CAM" will rollback even if successful.With the code below, I am getting this error after trying to do perform insertion:"ExecuteNonQuery requires the command to have a transaction when the connection assigned to the command is in a pending local transaction. The Transaction property of the command has not been initialized." [code]

I have an email function that needs to embed images into the email. I get the mailinto my pickup but the mail still asks me to "Show Images/Download Images". Some howthe images are not being properly embedded.I'm not sure what needs to be changed the examples I find on a lot of sites is very basic and vague.Additional info for clarity: This function will either download the images via url or embed them. This is determinedvia an external xml parameter. The physical path for the images, which replaces the URLs, is also in the xml.

My understanding of the Integer.TryParse() function was that it tried to parse an integer from the passed in string and if the parse failed the result integer would remain as it did before.
I have an integer with a default value of -1 which I would like to remain at -1 if the parse fails. However the Integer.TryParse() function on failing to parse is changing this default value to zero.
Dim defaultValue As Integer = -1
Dim parseSuccess As Boolean = Integer.TryParse("", defaultValue)
Debug.Print("defaultValue {0}", defaultValue)
Debug.Print("parseSuccess {0}", parseSuccess)
