DataSet Has Errors In Multiple Cells After Fill Method?

Mar 2, 2012

I am experiencing something very bizarre when I execute the Fill method of my adapter. I've been running this query for months and all of the sudden this is happening after I installed SP1 for Visual Studio 2008. For some reason several DataRows in 2 of the 3 tables within my DataSet have errors in them when I view them in debug mode using the DataSet Visualizer. Here is a picture of what I'm talking about

It does this to random rows. If I execute the Fill method the first time, rows (5-10) will have these errors. If I execute the Fill method again rows 12-23 are affected and so on. I have no idea what is happening here.

This is effected my DataGridViews, because they don't display any rows, because of the erros. I should also note that when I run the lines of code below in the Immediate Window it says the DataSet doesn't have errors.

?Me.ds.Tables("Current").HasErrors
False
?Me.ds.HasErrors
False

Specify A Custom Select Query For A Datatable Fill Method?

Dec 17, 2009

VB.Net 2005 SQL server 2005

I have a project I have a dataset that contains tables In the dataset designer, each table has a defaiult FILL command set. I have draged and droped my table as a grid onto my form VB automatically sets up the table adapter, and binding source to make it all work.

in my code, is placed in the form load routine, a tableadapter.fill(dataset.datatable)

Here is my dilemma. The data in my table may have 100's of thousands or rows.

I have presented the user with a front end that allows for filterring and selecting based on several columns. reguardless of how many rows the result set contains, there will always be the same columns in the dataset.

Because there are so many combinations of select query, i do not want to make 20 or 30 custom fillby's in the dataset. I want to make an addhoc select query and have the binding source and table adapters work as expected. I have created a query called "FillByCustom" in the dataset designer attached to the DataTable Adapter section.

My question is this.

If i build a select query that returns the desired rows, how do i place it into the adapter in place of the FILLBYCUSTOM select command, such that it all works as expected?

Make An Asynchronous Call To A Method?

Jun 16, 2010

I need to make an asynchronous call to a method which for the sake of simplicity counts from 1 to 100. If an exception is thrown during the methods counting process, lets say at 50 I need to stop the methods execution, dispose of a few objects and restart it at 51 but have no idea how to go about it.I basically need to raise an event from the method to the main thread and restart the asynchrounous method.

C# - Make A Variable/method/class Name Descriptive?

Aug 7, 2009

Sometimes to make a variable/method/class name descriptive I need to make it longer. But I don't want to, I'd like to have short names that are easy to read. So I thought of a special addin to IDE like Visual Studio to be able to write short names for class, method, field but be able to attach long names. If you need to - you can make it all long or you can make single name long. If you want to reduce it - use reduction, like two views of the same code. I`d like to know what others thinking about it? Do you think it is usefull? Would anybody use the kind of addin?

Make A Very Simple Asynchronous Method Call In Program?

May 1, 2012

I just have a simple vb.net website that need to call a Sub that performs a very long task that works with syncing up some directories in the filesystem (details not important).

When I call the method, it eventually times out on the website waiting for the sub routine to complete. However, even though the website times out, the routine eventually completes it's task and all the directories end up as they should.

I want to just prevent the timeout so I'd like to just call the Sub asynchronously. I do not need (or even want) and callback/confirmation that it ran successfully.[code]...

Make The Controls Stack And Fill Up The Available Space Left By A Control If The Control Is Hidden Or Removed From The UltraGridBagLayoutPanel?

Sep 8, 2011

I am wondering if anyone has any idea how to make the controls stack and fill up the available space left by a control if the control is hidden or removed from the UltraGridBagLayoutPanel.

Example:

[Textbox 1]
[Textbox 2]
[Textbox 3]
[Textbox 4]
[Textbox 5]

If I hide [Textbox 3] as of now, it will disperse the space left equally and pad the remaining text boxes with the space. However, I would like it to do this...

[Textbox 1]
[Textbox 2]
[Textbox 4]
[Textbox 5]

Where all the text boxes will move up and [Textbox 4] will completely consume the space left by [Textbox 3].

VS 2008 Make The "MouseProc" Method Be On A Separate Thread?

Mar 27, 2010

I'm working with Windows 7 and my application is having some troubles with the SetWindowsHookEx API - everything works fine but when my application is not responsive (gets into a loop) the hook automatically stops (LowLevelHookTimeOut) thats because my application haven't processed the hook messages in time (In this case, mouse movements).When I install the hook a method called "MouseProc" gets the hook messages (mouse movements and clicks) the problem is that this method ("MouseProc") is on the same thread of my app UI - is there is any way to make the "MouseProc" method be on a separate thread? I have attached the class.When the user declares this class as new the hook is automaticlly installed, here is an example:

Dim WithEvents MHook As MouseHook
Private Sub Form_Load(Some Args)
MHook = New MouseHook()
'Mouse hook installed

[code].....

But it's not really working.
