DB/Reporting :: [2005] Manual DataAdapter Failing?
Jan 8, 2009
Code:
dim Insert as string="insert into acaps(AppId,activity_dt,activity_cd,process_state,UserId,SeqNbr,LocCode,comments) values (@AppId,@activity_dt,@activity_cd,@process_state,@UserId,@SeqNbr,@LocCode,@comments)"
Dim x As New Odbc.OdbcDataAdapter(selectQ.ToString, DirectCast(Me._Cn, Odbc.OdbcConnection))
If x.InsertCommand Is Nothing Then

And have been trying things, but haven't found how to get it fire. At run time when I look at the value of the @Appid paramter it has the first row's value so it doesn't appear to be that.

I've got a VB2005 application written by a previous coder. I had to move it to a new windows 7 box, since the xp box it was hosted on had catastrophic hard drive failure. It worked fine on the xp box, but it fails on the windows 7 box.
More specifically, I've tracked it back to a specific subsection. It uses the Process library to start pscp, the putty scp command line tool. It has a timer to wait 400 seconds for the process to close, otherwise it stops the process and reports an error.
Unfortunately, on windows 7 it doesn't seem to even start the process, because it does not wait the specified 400 seconds, nor does it report the other error it would give if pscp did start, but failed. Is there a compatibility issue with the process library, or is it some configuration issue?
Update:
Alright, after more testing I've determined that the subprocess is getting spawned, but the parent is not waiting for it to exit.
it seems the VB code myProcess.WaitForExit(40000) is not actually waiting until the process exits. Is this because it can't 'see' the process and believes it has exited?

I have this VB ASP.NET Web Service Application project running VS 2005. I'm trying to add references. To do so I click on the "Properties" icon in the Solution Explorer window which presents me with a window to add/update/remove references. I click "Add", I select the reference I want and then "OK". Lo en behold, NOTHING! It simply won't add references (I tried adding several different ones). Specifically I'm trying to add the System.Configuration assembly.

Can these two things work together? That is VB.Net Standard NOT VB.net 2005 or vb.net 2008 or any other year. If not is there an inexpensive solution for reporting in VB.Net Standard and SQL server?

I'm building an aplication with an MS Access database behind the scene. In many of my forms I'm gonna use DataGridViews to show data from the database, not an entire table but data based on manually built queries. So, I have few questions without answers, by now. Solutions or 1. I haven't decided how will I bring the database into the project: from the menu -> Add New Data Source, or within the code, at runtime. I still don't know which one's best or why.2. How exactly can I execute any SQL query (SELECT, INSERT, UPDATE, DELETE etc) on my Access database from my aplication?

I have recently wanted to start work on an application that uses an MS-ACCESS database. The problem is that no matter what I do, the actual database will not retain any records added. I have followed the Microsoft examples to the letter and it does not work. As long as I have my app running I can add, edit and delete the records. As soon as I close it and run it again, all the records are gone. The mdb is not read only, I've checked it. I also decided to try the my video collection example program that is included with VB 2005 and it will not retain any records either. Is there any code I need to add to get this to work or is my copy of VB 2005 broken? This is extremely frustration because I plunked down a lot of money for Visual Studio 2005 Professional. This is a key feature and it should work. Microsoft had me do a reinstall and apply a couple of patches and it still did the same thing. They told me either I am not coding it right or my system is flaking out. I did a fresh install of Windows (I even formatted the drive before installing), and reinstalled VS yet again and even with that being the only program on there, it still will not work. So I installed all my programs again, restored my backups and now a day and a half later I am writing this.

I have just installed VB.NET 2003 and I am trying to manage some databases using SQL Server 2005 Express.When I try accessing the database via the data connection tab, I get the following message.
Quote: You have connected to a version of SQL Server later than SQL Server 2000. The version of Visual Studio or Access that you are using was released before the version of SQL Server to which you are connected. For this reason, you might encounter problems.
Please check with Microsoft to see if there is a service pack that you should apply to Visual Studio or Office in order to get support for the version of SQL Server to which you are connected.You can continue but any new object types might not be enumerated, and it will not be possible to save any objects or database diagrams that you create using the Visual Database Tools.I can not add tables or manage data fields. Does anyone know how to get the patch referred to in the message above? I can not find it via google or this forum.

I have a small problem, I have written a small application to update a database table. Now on my computer I have a copy of the database but using MSDE 2000 and when I run my application it works perfectly, however I also have a copy of the database attached to MS SQL 2005 on another computer. Now when I got an run my application on this machine, it fails with a "Time out" error. I have changed the timeout settings on the SQL Server however it then just sits there for ages, whereas when I run it on my development machine MSDE 2000 it loops through the code quickly.

I'm looking for some simple code that lets me create a Microsoft Access table via code.Currently all I do in Access is write and retrieve data from specific tables but now I want to be able to create them at runtime. Here is an example of the code I use to load some data just so you can get a feel of what I'm currently doing. Hopefully there is an easy way using the same rough way that I'm currently dealing with databases.

Public Sub LoadCareer()

I'm currently using SQL Server 2005 and I've created a business intelligence solution that has a "Package1" copying a table from a database to my local database. I tried executing this package/solution from my .Net IDE and it worked.
Later, I tried creating a job that will execute the package at the intervals of 1 hour per day using SQL Server Agent but when I get to the part where I select the type of job (under the "Job step property", I can't find the job type of "SQL Server Integration Services Package". I've been following this: http://www.mssqltips.com/tip.asp?tip=1180 tutorial but I can't execute my job probably because I'm using an incorrect job type.

I have a datagridview that I'm populating from a SProc. The data coms back fine and is presenting in the DGV without any trouble, but I don't like the order the data is being returned in.A long solution might be to modify the SProc to return the data in a different order, but I prefer to handle this on the UI for simplicity. Also, I know the user can re-order but that presents a specific poblem in the way the columns are structured.Is there a way to programmatically change the order at runtime?Here's the ode I have on the UI. If you need to see the adapter class also, please let me know and I'll present it, too.

I have done research on how to manually create sorting in a grid-view and none of it is thorough enough for me to follow. I need more of a step by step solution, like what event should my sorting code go in, how would i enable the headers to allow sorting. normally, i just have .net do this but for some reason this time it doesn't allow it, maybe because i am not using a datasource.that's my code that creates a datable and then binds to the gridview.
Function toptable()
Dim reader As SqlDataReader

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near and I don't know how does this happen because whenever I check the SQL that I have made including the inserted data, it shows no error.

After clicking the button a message box appears and says, "Update is available for download" as you would expect but after clicking the ok on the message box my application goes into a not responding state and I have to close it with the task manager. The application builds successfully and I have a reference for System.Deployment added to the project. Everything in my application works fine as long as I don't try to do an update. Any suggestions on what I should check or do? It should actually say "no updates are available for download" since the version of the program that is being used is the most current version.

If I turn off automatic updating of a binding data source by setting DataSourceUpdateMode = Never and then use a button to update the whole lot (using binding.WriteValue), a problem occurs - Namely, only the first bound control's data source is updated. All other controls are reset back to the original values.This is because when the current object changes (as happens after the above WriteValue), if ControlUpdateMode = OnPropertyChange, then all the other controls re-read in the value from the data source.
One way is to derive a class from BindingSource and add a WriteAllValues method.This method does the following:
(1) For each Binding, save the ControlUpdateMode
(2) For each Binding, set ControlUpdateMode = Never
(3) For each Binding, call the WriteValue Method
(4) For each Binding, reset ControlUpdateMode to the saved value
(5) For each Binding, if ControlUpdateMode = OnPropertyChange, call the ReadValue method.
If working with your own classes, would implementing IEditableObject resolve the issue?In another control I'm working on, I implement my own binding. The way I get around the issue in that is with the following code. (I've put in the bare minimum, I hope you can follow it!):
Private Shared ControlDoingExplicitUpdate As MyCustomControl = Nothing
Private Sub UpdateDataSourceFromControl(ByVal item As Object, ByVal propertyName As String, ByVal value As Object)
Dim p As PropertyDescriptor = Me.props(propertyName)
[code]....
So, when UpdateDataSourceFromControl is called, all the CurrentItemChanged events will be called for all other controls in the same BindingSource. However, because ControlDoingExplicitUpdate is set, they will not re-read in the value from the data source unless they happen to be the control that did the updating.ControlDoingExplicitUpdate is set to Nothing after all these events have completed, so that normal service resumes.

I have a DataGridView on a form in VB 2005 Express, of the 10 columns i need on this DGV 6 of them will be pulled from an MSSQL DB and 4 of them i need to manually enter. One thing i have going for me (i think) is that the 4 manual columns have the same data in each row.I have been filling this DGV using a datatable, but i am not figuring out how to add manual columns and databound ones in the same DGV. My column layout would look like this:[code]some one please explain to me how i would do something like this. if you can include the datatable definitions also it would be a big help, in order for me to verify that i am at least doing that the right way.
