VS 2008 : SQLException Chose A Different DB, Cannot Attach File?
Aug 12, 2010
This may or may not need to be moved to the deployment folder...Okay I have a vb.Net application that connections to a sql server 2005 database "TacticalDB" while debugging the application I was using the connection string,
Dim con As SqlConnection = New SqlConnection("Data Source=.SQLEXPRESS; AttachDbFilename=" + Application.StartupPath + "DataTacticalDB.mdf; Database=TacticalDB; Trusted_Connection=True; User Instance=true")
Which works fine, but I have moved into getting the application ready for deployment and so I created a setup application in the same solution as the application. Now I have added the database file with the setup but when my application gets to the con.Open() line it catches an exception,
System.Data.SqlClient.SqlException: Database 'C:UsersJohnDocumentsVisual Studio 2008ProjectsBlackout_ScoutBlackout_Scoutinx86DebugDataTacticalDB.mdf' already exists. Choose a different database name.
Cannot attach the file 'C:Program Files (x86)MicrosoftSetup1DataTacticalDB.mdf' as database 'TacticalDB'.
[code]....
Now I only have the one place where the application should look for the Database and thats Application.startupPath/Data/TacticalDB.mdf and if im running the newly installed exe it shouldn't look back in the myprojects folder but it is.

I am quite new to the VB scene, and am still quite confused by the variety of options presented as far as choosing the correct project type.I have been coding for roughly 4 years now and consider myself still to be a beginner. My past experiences include, hmtl, C++, vba, assembly, and a few others which I'm sure currently escape me.However, VB is a whole new boat and I'm just not sure where to get started with what I want to do.I've Googled the internet, went through the MSDN, and even did some tutorials.My current dilemma is I wish to make a program that will do a the following: Allow a User to download a set of data from an embedded web page.Open an excel file Download more data from a different web page.Open another excel document..I'm sure this is probably quite simple to do (read: I hope...). However I'm just not sure where to begin as far as choosing a project type. Additionally I'd like to have it set up with buttons, where button1 reads something along the lines of "Step 1: Click Here to Go and Download Data", "Step 2: Click Here to browse to excel file", etc etc.What type of project do I chose to get the stuff done on my list?

I'm using VB Express 2008 and MS SQL Express 2008. I have a couple of tables in my SQL database and among them are some log tables that track changes in the data entries of the substantive tables and fields I have. I have one log table fore each of the datatypes that appear in my substantive tables.
For example any change to any field in a substantive table where the field is of a bit type will be logged to the BitTypeLogTable. All of my log files are structured essentially the same. For example the structure for my BitTypeLogTable looks like this:
The other logs are identical except that the OrigValue and NewValue fields have different datatypes according to the datatype they are intended to track. For example the datatypes for those fields in the DatetimeTypeLog is datetime and in the MoneyTypeLog is money.
Each of the substantive tables in my database has three triggers which cause entries to be made to the log tables when the substantive fields are changed. For example, one of the UpdateTriggers looks like the following:

Basically I have to create an application which is a quiz. According to the users score it will then determine what level of skill they have.I know i could do it really easily, by having a number of labels on the form which hold the questions. Then underneath have radiobuttons with possible answers. From this then use an IF statement to add a digit into an invisble label which can tally a score of correct answers. Assign each invisible label a variable which then can be summed in another label, from the score then use a SELECT CASE statement to let the user know what level they are at.But I know that this would mean alot of code and objects on the form. I have read that it would be more efficent to use an XML or TXT document to populate a label and radio buttons, this way it would also be easier to change questions and randomise them.The only problem is that i dont understand how to attach the XML or TXT file to the form so that it does the population of labels & radiobuttons.

I have no experience on this matter, so I do not expect anyone to explain in details how this is done, just point me in the right direction, maybe tell me what the correct name for this is. I'm sure it is pretty commonly in use.
I think the best way to explain this, is through my exact need. So, I have a button on my website that should cause the user to download an exe file. The exe file pretty much gathers a few informations from the users PC, and post them to my data-base through a web-service. Now my problem is, these informations should be assigned to the user who downloaded the exe file's row in the DataBase.All this would be solved by assigning a single Integer value(the users ID) to this exe file on the download request, and then a way for the exe file to also get this value assigned to it, but how do I do that?
My language is asp.net for my website, and the exe file is written in vb.net.I know I could fake this by making the exe file show a login-form and get the user-id this way, but I really like the application run without the user noticing to much.

i have a windows form created using vb.net 2005 that allows users to attach files. When the user clicks the AttachFile button, they browse to select a file they want to attach and then the code places the file they selected into a predetermined location. The primary file type they will be attaching is a windows meta file (.wmf).
The attached file is saved and appears as a hyperlink for the user to open at a later time. When the user clicks to open the file, it is suppose to insert it into Autocad; however, it wasn't doing this.
The problem comes from attaching the file using the StreamWriter for some reason its not working correctly. I verified that this is the issue: When i hardcoded the file path to the original file's location, it opens up just fine when clicking the hyperlink. When I compare file size from the original to the one attached, I see that the original is 12Kb and the one I attached is 19Kb.
Here's my code to attach the file: I'm thinking perhaps it has something to do with this line? sReadFile = sr.ReadToEnd() but I'm just not sure. I tried changing this line to sr.Read but that doesn't work either.

I tried to start using VB 2010 Express with a program I originally developed with VB 2005 Express that I moved to VB 2008 Express successfully a couple years ago. It uses a database file (*.mdf) that is on the computer ( not out on a server). When attempt to run the program in debug mode, I get the following error "An attempt to attach an auto-named database for file C:Documents and SettingsTomMy DocumentsQuizzing StuffQuestion Database 2010QuizQuest ionGameQuizQuestionGameinReleaseQuizQuestionDB.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share."
I first made a copy of the entire project folder that was working in VB 2008 Express and gave it a different name. In VB2010 I opened the project in the copied folder and it said it successfully converted the project. I am able to open the Data Source inthe Designer and see the database structure as I expect. I think the project is still using SQL Server 2005 Express (because it is what is checked in the list of prerequisites on the Publish tab).
Note, I have programmed off and on for many years, but fairly new to using databases and SQL Server.
