View 2 RepliesI'm using Visual Basic Express 2010 and SQL Express 2008 in Windows XP. At first I couldn't add a datasource (the .mdf file for the database) because of a "Operating system error 32" which I seemed to have resolved by giving myself full permissions for .mdf file (by right clicking on the file and going into properties and then Security) and restarting the SQL SERVER (SQLEXPRESS) service. The dataset for the database is in my solution explorer but when I right click on a table adapter to add a query and attempt to open up the query builder, I get the error in the title above.
View 1 RepliesI'm a little stuck here and maybe some of you can point me in the right direction ... maybe even get me a solution. Well, I do query a table but before everything I need to get the SQL Query to create the Table (like you get, when you select to option "Create to" in SQL Server Management Studio). For example like this:
[Code]...
I am using/creating a DataTable so the "enforceConstrains" property is not avilable for DataTable.Error message: Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints.

When Creating a query using the sear Criteria Builder. I keep getting the error:
"The schema returned by the new query differs from the base query".
I know this means that the error is due to the query attempting to return too little columns. I have 3 rows in a table but I want to display one. I am currently using a list box what alternative is there.
I'm using Visual Basic Express 2010 and SQL Express 2008 in Windows XP.I created a database on my local PC HDD.

View 10 RepliesI created a typed dataset a day or so ago, then I added a whole bunch of tableadapter/tables with some relationships etc... suddenly out of nowhere it decides my dataset "is not defined". everywhere in my code where i use this dataset now has an error. I tried not to pull out my hair and do a Clean then Rebuild solution... out of nowhere it just refuses to generate code. Object reference not set to an instance of an Object. It would be nice if it was my object so i could find it but it's not.
Curiously I also lost the little database icon on the dataset in the solution explorer.I can still open it in the designer and preview my queries etc... it just wont make the code. it's driving me insane. anyone got a solution?
I have an imported sql database using pa as the schema instead of the default dboThe problem is when I go into vs 2008 and create a gridview control, it won't recognize the from table object. I get "invalid object name" unless I go directly into the code and put the database name and schema name in front of it.

...until an indeterminate amount of time passes and I get "The ProviderManifestToken '5' is different from '5.1' that was encountered earlier" error. Why is it encountering a '5' to begin with when I've only specified '5.1'?!!?The only way to get the error to stop is to reupload to edmx file (which has not changed at all), overwriting the previous one. At that point the application will happily chug along serving data to users until BAM the error occurs maybe a few hours later, sometimes days later and I'll have to start chasing my tail again.I've tried changing the ProviderManifestToken="5.1" to "MySQL", "6", "5" and the same situation will occur: works for a while then the error. As a bonus I only have this ONE edmx file in the vb.net webforms application so what is it getting confused bythe first few lines of my edmx file looks like:
<edmx:Edmx Version="1.0" xmlns:edmx="http://schemas.microsoft.com/ado/2007/06/edmx">

I created a SQL DB named MainDB.mdf and a small VB 2010 application with some forms and datasets.Everything was working OK until i got a new computer and re-installed Visual Studio 2010 and SQL server 2010 on it. I copied my DB from the old to the new computer and also copied by VB 2010 project to it. I used Windows Authentication to connect to the DB in the old computer and also in the new one, i am using different Windows user account names though.
I was able to connect to the DB in the new computer in the Server Explorer section, i created a new connection string to the DB and i can seed there is data in the tables. When i run my VB 2010 application created in the old computer get error:
"Cannot open database "MainDB" requested by the login. The login failed. Login failed for user 'D630Admin'."
I need to get rid of that error and be able to add/mod/del data from my DB using my VB application as i used to.

I have 7 company Divisions that sit in an access database.I then use this list to populate two comboboxes in my windows form.However I get a syntax error in my SQL Query if the Division name is more than one word.For example in my access database I have two columns one is a status column and the other is a division column. If for example the Division is called 'Corporate' the status column is called 'Status Corporate' and the division column is called 'Corporate'.The SQL query works fine in this scenario.However if I have a Division that is more than one word, lets say 'Operations Division' I get an error in my SQL Query that says -

I am writing a program to try and centralise alot of data i have on my network so i can use them as templates and guides. My intension was to have an easy to browse program with links in the program which open the particular file (eg.

For those who still have lots of legacy code as I do in .NET 1.1, has anyone found a solution for this issue[url]...
The directory given in the command line will not exist, which makes sense given the error message. The problematic part is that everything works with a full rebuild. Since the "work around" is so easy, Microsoft of course is not going to fix the problem for .net 1.1.
To everyone who pre-emptively suggests an upgrade to .net 2.0+, that is not an acceptable solution, due to time limits and resources. To those who say that is not an acceptable excuse, go find another thread, not every company is perfect.
