I used the query designer to create a qry from a datagrid view in vb2010 express, the idea was to work out which diver logged the most minutes in the water. here is a copy of the sql syntax:
SELECT MemberID, Name, SUM(DiveTime1) AS D1, SUM(DiveTime2) AS D2, SUM(DiveTime1 + DiveTime2) AS s1
FROM Triplog
GROUP BY MemberID, Name
ORDER BY s1 DESC
I'm using VS2008 and SQL CE 3.5, building a smart client app. When I add a table adapter with this code:
UPDATE feeders
ET planningAreaID = @areaID
WHERE feeders.transformerID IN

I created a new query in the dataset designer. There are now 2 queries there. The original one and the new one.I also added named parameters in the Where clause of the 2nd query.This is the query in the new one:
SELECT ID, FatherName, MotherName, EmergencyContactName,
EmergencyContactRelationship, Address1, Address2, City, State, Zip,
PrimaryPhone, SecondaryPhone, Emaile.

I am attempting to update an existing winforms application, that was created with a dataset control on all the winforms pages. I have ported it from VS 2008 to VS 2010 and I need to update the database section and connect it to the SQL backend using traditional code method.In the Solution explorer, when I click on the Dataset files, and click "Exclude From project" I am unable to build the project.Is it advisable to comment out the code lines that refer to the dataset in the .designer.vb files?
View 1 Repliesi'm trying to make a login form connected to an sql server database. my data base has records like this:
fname - lname - minit
each name in a separate column, and i wanted to use the name as the login username, so in the dataset designer i made a new column and concatenated the names together like this: lname+fname+minit but at Dim dr As SqlDataReader = cmd.ExecuteReader i get this error:
"Invalid column name 'username'. Invalid column name 'username'."
i'm asuming that's because username doesn't actually exists in the database, only in the dataset.is there a way to get that to work with out the username column actually existing in the database?

I was wondering if anyone knows of any way of statically linking all dependant DLL's to the vb.net program? I know there are ways to find the dependencies using dependency walker and other tools like that. But was curious since c++ supports the static ability to load DLL's. If not, what tools can i use to quickly package the required DLL's without having to install .net on all my systems?
View 4 RepliesI 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 -

View 1 RepliesWhen using the Dataset Designer in VS 2010 I add a new query.It adds with no issue.Add another,starts to hang. Add another and now it can hang for hours.I use task manager to kill VS 2010 after 30 minutes.Go back into the same table adapter query, modify it, save it.Works in seconds.Add another query, hangs, hangs, hangs.I have seen posts about this going back to VS 2008.I have No Add-Ons loaded, what is causing this issue??
View 2 RepliesIt seems that there is no way to preserve changes to a DataSet made with the Designer when there is a change to the database. The only way to get the Designer to rescan the database to incorporate a change is to delete the DataSet and then recreate it. This of course blows away all the mods you've made in the designer. There should be a way to have the Designer rescan the database while preserve all the mods that have been made in the Designer. Otherwise the Designer is essentially useless after the initial generation of code. What am I missing?
As a workaround, I tried incorporating the changes to the database by making the same change in the Designer rather than recreating. However, clearly no one tested this is it only partially regenerates the code based on the change. Try changing a field from nulls not allowed to allowed. This works when you add data to the DataTable, but bombs as soon as you update the database, because the DataSet code does and the database code doesn't get regenerated.
I have a windows form application made in Visual Studio 2010 SP1 Rel. I'm using SQL Server 2008 R2 for my database. I've been working on this project for a while now and I am almost completed with it. I recently had to add a field to one of my tables in my database, which hasn't given me much troubles in the past as I've had to do this before. To make sure I did it properly, I'll tell you how I added the field. I went to my database on my server and went to my table, tblOrderParts. I right clicked, and went to design. I added a field, Order_Delete, which I made a bit field so I could use a checkbox. When I went to my dataset designer, I used the wizard to add the field to the table in my program.
After I added it, I remembered that one of my forms was using a view I had created with that table that would need the checkbox as well, so I went back into SQL Sever to add that. Added in SQL with no problem, but when I went back to Visual Studio's dataset designer to add the field to my view, it won't allow me. I open the wizard, go to my view i created, vwAllOrders, and checked the box next to it. When I press Finish, though, I get, "An exception has occurred while attempting to set the data source generator property." I had to cancel out of the dataset wizard cause it wouldn't let me continue... even if nothing was changed.
Now it is also showing me an error in the Error section saying,
"Custom tool error: Failed to generate code. Exception of type 'System.OutOfMemory' was thrown."
Now that I've said the error, here's what I'm thinking is going on... Something must be wrong with the custom tool on my dataset. The tool name is MSDataSetGenerator. I went on more forums, and a couple mentioned trying to restart the custom tool by right clicking the dataset and going to "Run custom tool.' When I run it, it gives me another error. Not much different, but still different in wording.
The error it pops up say
"The custom tool 'MSDataGenerator' failed. Exception of type 'System.OutOfMemory' was thrown."
I have a dataset that is filled by a tableadapter and what I'm trying to do is to figure out how to loop through all of the rows in my dataset and determine when someone has edited/changed the row and then to post those changes back to my database.
View 1 RepliesHowever, now when I open it in design view and add a new tableadapter I now cannot reference the new objects from the code. Likewise if I delete one of the existing tables in the dataset, it still appears to be there from the code (ie in intellisense)Similarly, when I examine the .xsd file, the changes I've made i the designer appear, but the changes are NOT happening in the dataset.designer.vb file. It's as if the two files are somehow out of sync
View 3 RepliesVB.Net 2010 Express - AMD Phenom II X4 - 8g ram There are times when I debug the app that I get the 'End Sub' must preceded by a matching 'Sub' error. This usually happens after I make a change to the table adapter query in the dataset using the designer.
If I dblclick on the error it opens the dataset.Designer.vb and shows the error in question.
First, I have made NO changes to this file manually Second, when looking at the code in question, it actually appears there is nothing wrong with it - yet the compiler thinks there is.
This appears to be a VB.Net 2010 IDE/compiler bug Now, I can resolve this error by re-opening the dataset, configure the Fill query, click Finish (not making any changes - just clicking Finish), and then save and close the dataset.The error goes away then, but I shouldent have to go through all that; especially since my query was fine to begin with.
in my VB.Net application I've created a Dataset that call an existing MS SQL Server stored procedure but after the wizard close no columns where added... how can I add all the columns returned by the stored procedure without adding them manually (off course the stored procedure might change in the future) in which case manually will not work.
View 1 RepliesI have a dataset with around 15 table adapters. Everytime I make a change, such as add a column, change a type, or just anything, it takes around 3-4 minutes before studio responds again. The processor and ram are in good shape, but there is a spike in network usage by devenv during this time. In fact, devenv has the higheset network usage all together, even with with IE open and browsing. Why would this be and is there any remedy?[code]...
View 3 RepliesThe DataSet designer will stop refreshing itself every now and then in VS2008. This means I cannot work with my DataSets until I restart VS. There is a more detailed explanations in
this thread, but it was incorrectly marked as answered. This issue is taking more and more of my time though, so I'd like to get another answer now.
I would like to know where the dataset designer is obtained for a vb.net 2008 appliocation I need to work on. Is this part of the initial install for visual studio.net 2008. If so, what part of the initial install will I find the dataset designer? Is this a plugin that needs to be downloaded? if so, what URL do I need to use to obtain the plugin?

I have a typed dataset with table adapters. I use this method because it makes it easier to design the layout of my DataGridView.The problem is I have added a new table to my dataset.

In MVC design pattern i should return objects to the controller (in this case i used only the view- win form) becuase of my Designer created DAL i cannot return objects of Employee and Designation to the View... this is becuase in BLL: the following method

I'm using a DataSet to interact with an accdb file in an application. While debugging, the app occasionally closes, without warning and returns the stack below. The code causing the exception is in the DataSet.Designer.vb file (automatically generated). What's curious is the line that reads:
If (previousConnectionState = Global.System.Data.ConnectionState.Closed) Thencommand.Connection.Close()End If Why would the code try to close an already closed connection?I just change the "=" to "<>"? Will it stick? (since it's auto-generated, I'm sure it will revert if I modify the dataset, right?)
