Namespace Missing In VS 2010?
Jun 21, 2012
I have installed VB.NET express 2010 version and I am trying to create a new dll file for use in my SSIS packages. When I try to write the code, the VS environment tells me that I dont have the Microsoft.SqlServer.Dts.Runtime Namespace. What can I do to make this possible?
I looked around on internet but couldn't find anything substantial. I also have BIDS 2008 which I use to create packages. I cannot uninstall that because I have some work to do on a daily basis.

I need to export the contents of DataGridView into an Excel file. There is lot of discussion which I went thru and leaves me more confused now than before. I am using VS 2010 Express with Office 2007.
In the VB project reference components, I looked for Office components and did not find it there.

I'm trying to access the "My" namespace, and it's missing everything except "Settings", "MySettings" and "Resources". I've looked in Microsoft.VisualBasic.Devices and all the references seem to be there, by the My namespace itself isn't working right.
Another thing that's not working is the ''' XML documentation function. Normally, typing those apostrophes in the right place spawns a big mass of UML commenting for Intellisense entries but now, nothing. I've tried both of these from my user account on the same PC and they work fine; presumably it's something my predecessor has inflicted onto his own settings in VS2010.
Does anyone know how I can fix this and go back to using Visual Studio as I know and love it? EDIT: I got sick of this behaviour and decided to move over to my username, where I'd verified the My namespace was fully working. Turns out that the problem reoccurred once I'd gotten the project working under my username, so it's presumably a project setting which has been turned off somewhere, as starting another project still creates an environment where "My" and the ''' comments work, but the problem project still doesn't have either feature.

I need to read an xml document from a database record into an XDocument object in order for it to be deserialized. So that the deserialization will work, I need to apply a specific namespace to each of the level 1 elements. So XML looks a bit like this:

How do I prevent the blank/empty namespace being added to each child element of the element to which the required namespace has been applied?

I'm having trouble with the code editor. I was exploring different functions and one of them that I clicked made the hidden code that VB uses to override to clean the form visible. This had lead to many issues. There is a partial class that is missing "end class" statement. When I put in the end class it makes nearly everything get a "not a valid namespace" error. I do not know how to fix this.

I am working with a .csv file that is generated from a Java-based application. It mainly contains contact information. I can see the data when I open it in Notepad, Excel, and Access. However, when I attempt to read the data file in using the following code, I get blank data. I accidentally discovered that if I open the .csv in Excel and then save the file, my program will read it in perfectly.

I have a problem in VS2010 with a user control i have created, I wonder if this is a known problem and if there is a resolution.
My project has a root namespace of DEV2.MyApp.I have created a user control and dragged it onto my form at design time.In the designer i get an error for that form that goes like this:-
Type DEV2.MyApp.myCtrl is not defined Me.myCtrl = New DEV2.MyApp.myCtrl ()I correct it by removing the namespace DEV2. like follows.Me.myCtrl = New MyApp.myCtrl ()
However, everytime i make an amendment to this form on the designer, the error creeps back. Its really annoying and I dont really want to resort to having to create the control at run time to get around it.

This class is located in the namespace Acme.Infrastructure.Interface.A class with the same name EventArgs exists in the System namespace.In another project in my solution I have a class Acme.BusinessModules.MyModule.MyClass.When attempting to use the EventArgs class I have to fully qualify the class name or the compiler thinks I am using the System.EventArgs class.My understanding of namespace resolution was that the compiler would first look for the class in the current namespace, and then its parents. It seems that the compiler checks in System before it checks in sibling namespaces. Is it correct that System is checked before the sibling? Or is this behaviour caused by other issues (Imports order?)?

I have a class library that is referenced by several other class libraries along with the main program. About two weeks back, I made a change to one of the classes in that base library, which is used as an argument for some events. Since that time, I have been testing code. Today, after a couple more tests, I started getting this exception. It is indicating a field is missing, which was renamed in that change about two weeks ago. The exact code that is raising the exception is code that I have run a couple dozen times in the intervening time, and it has always worked.I have tried everything I can think of, including deleting the bin and obj folders of every module that could be in any way related to this issue, such that the whole thing was rebuilt. I have removed the references and re-added them. Nothing worked. Code that has run fine for weeks has decided that it wants a version of an object that has not existed for weeks.
This problem arose immediately after a different problem, so the two might well be related. The other problem was that, while stepping through code, the IDE decided that one of the code pages was different from when it was last loaded. I get that a fair amount, and solving it is fairly routine. It generally means that I am stepping through code in a dll, and inadvertently tried to fix a bug in that code, rather than in the dll itself. Now it no longer matters. I can't get to that code page, nor can I get to anything else in that dll. It is acting like it has sponaneously decided to revert two weeks back in time, and use that source code for debugging, despite any attempt I make to bring it up to modern times.

I'm working on a grid of cells that is something like a DataGridView, but not really. The two are close enough that you can picture a DGV for the purpose of this question. What is actually there (and this is true for actual DGVs) is a set of cells drawn on the screen with a couple scrollbars for vertical and horizontal scrolling which are only drawn if there is too much data to show in the visible cells. There aren't more cells than the ones that are visible, so when you scroll the scroll bar, it looks like new cells are being displayed, but what is actually happening is that the existing cells are just being filled with different data depending on the position of the scrollbar. The key observation is that the set of controls displayed in the grid is always the same (unless the grid is re-sized, but that's not relevant to this issue). The appearance of those controls can change, but the controls themselves do not.
One of the features I am adding is the ability to drag-copy data similar to how Excel works. In my case, if you click on a cell, then drag outward (move the mouse while holding the button down), all the cells in the selection rectangle are tinted green. This works nicely. Some of the cells are enabled, while others are disabled. If the drag selection includes disabled cells, those are not tinted. Only enabled cells can be selected, though a drag can cover disabled cells. The relevant point here is that some cells are enabled and some are disabled.
The feature that I am adding is the ability to do drag selection beyond the visible edge of the grid. The grid is a monthly calendar, and I simply can't get 31 cells onto even a wide-format screen. What I am trying to do is allow the user to do drag-copy onto days that are not currently visible. The way I do this, the user clicks in a cell, then drags out to the border, at which point the grid scrolls (the scrollbars move, and the contents of the cells is updated as a result of the changes to the scrollbar value). This is largely working.
The way I handle the selection is that when the user presses the mouse button while over a cell, a flag is set to indicate that the button was pressed, and the current cell is recorded (so that I know where I started from). MouseMove events are used to figure out what new cells the user has visited, and set the selection area based on whatever is under the rectangle described by the initial click point and the current point. Lastly, when the user releases the mouse button, the MouseUp event initiates the actual copy. At that event, I know that the user is done with that copy action. Therefore, the MouseUp event is kind of critical, and therein lies the problem.
As I mentioned, some of the cells are disabled and some are enabled. Disabled controls don't raise events. If I click on a cell, it HAS to be enabled, but that's fine. The problem is that if I then move the mouse in such a fashion that the grid scrolls such that the cell that I had initially clicked on is no longer enabled, then the cell doesn't raise events any more, and the MouseMove and MouseUp events stop happening.I only see one viable solution, which is to not toggle the enabled state of the grid cells. Instead, I would have to have to add a custom property that would make the control act and look disabled as far as the user was concerned, but it wouldn't be disabled as far as the program was concerned such that it would keep raising mouse events. This would be pretty rough, since I would need to prevent the control from appearing to have focus even though it technically would have focus

I'm trying to print my form which I created with Visual Studio. I'm using power pack printing. All goes really well but I'm missing 2cm on the right side of my printout. Page on printer is set to A4.
This is what i try to do but no luck:
PrintForm1.Print(Me, PowerPacks.Printing.PrintForm.PrintOption.ClientAreaOnly)
Whatever I change, it is always printing the cropped page. I'm using xps printer at the moment and there is no zoom option. Can I set the form to zoom to fit the page?
The borders are also too big. Thats why my printout gets cropped, but I have no idea how to change it.
The size of my form is 711 x 1034 pixels, it's a desktop application.

I am developing a software that catches streaming data. Unfortunately, there is no pattern or sequence on how this data comes in. So what I have initially done is to catch then write to my MS Access DB. Unfortunately, while writing to the DB, I am missing some data that is streaming since writing takes a little bit of time before it goes back to the catching syntax.
I am planning to multithread the DB writing then just call it from my main program. Do guys know any website/tutorial where I can learn the basics for multithreading? I am using Visual Studio 2010. Or if ever, does any one of you have a sample program where I can just learn from?

When I'm coding in Visual Studio 2010, say that I have some interface:
Namespace Some.Huge.Terrible.Namespace.Adhering.To.Company.Standards
Public Interface MyInterface
...
Property SomeThing as String
...
End Interface
End Namespace
And a class:
Public Class CoolThings
Implements MyInterface
When I hit Enter after MyInterface, Visual Studio will put
Property SomeThing as String Implements Some.Huge.Terrible.Namespace.Adhering.To.Company.Standards.MyInterface.SomeThing
I would like it to, instead, simply put:
Property SomeThing as String Implements MyInterface.SomeThing
It does the same thing for all methods, etc. that I have to implement and it's mildly annoying to either have to look at a stupidly long reference, or clean it all up since I'm importing the namespace at the top of my class anyway. Is there a setting in Visual Studio that I can use to switch that?

I am building a tool that takes an XML document and replaces XML nodes with a different XML node using .ReplaceChild. This all works great. The nodes get changed to the proper nodes. Where I seem to be having an issue is that the new node is inserted with an xmlns="" attribute, which I am not specifying for it to do, nor do I want as an attribute. How can I stop the ReplaceChild from inserting this as an attribute, or am I going to have to remove the attribute after the node is replaced?
Dim imgSrcNode As XmlElement = xmlDoc.CreateElement("img")
Dim imgSrcAttr As XmlAttribute = xmlDoc.CreateAttribute("src")
imgSrcAttr.InnerText = "./art/" + imageName.Substring(0, imageName.LastIndexOf("."))
imgSrcNode.Attributes.Append(imgSrcAttr)
mmlNode.ParentNode.ReplaceChild(imgSrcNode, mmlNode)
Resulting XML change:
<img src="./art/equJI161298_1" xmlns="" />
XML change desired:
<img src="./art/equJI161298_1" />

This now prevents me from running in debug. I have not used Publish in the Build menu or used ClickOnce. The Project - application page has "enable XP visual styles" checked.

I am in trouble with publishing my project that uses an embedded database file. I publish my project but when I try to install and run it, it gives me an error as "Unhandled excception occured in your application. Database.accdb file could not be found." I understand that the problem comes from the missing database file. But in the project I assign this file as "content" and I believe that it should copy the file to the required folder that way, right? I also tried to "compile the file" in project but if I make it, visual studio gives an error.
