First of all, you don't need to worry about disposing managed objects all the time. The garbage collector will take care of that eventually. Disposing it just cleans it up immediately.
Second, the using statement merely causes the Dispose method to be called on objects that implement IDisposable. The DataTable is not tied to a SqlDataAdapter (i.e., not a field or anything else that gets disposed). Because you're giving the DataTable a name, the result have to match that name to be filled. Use a TableMapping mapping or don't give the DataTable and name and see what you get.
And yes, had you mentioned that you were setting the CommandType, I wouldn't have mentioned that. The default, however, is CommandText so it was worth mentioning from my perspective with the knowledge you provided.

Got it.. thanks for the assist. Unfortunatly, I have to worry about early disposal of my objects because I am running this on a shared server in the company and I need to really, really, REALLY manage my memory usage (***sigh grumble***)...
Thanks Heath...

i'm using the dotnetmagic.com docking component.
i want to develop the content of each dock in a library of its own. ( not using the dotnetmagic component ) the idea is to be able to re-use the same objects if i end up changing things to the application later.
for example, i have a search ( in a group box ) and a datagrid. i want to be able to call them from their own class.
should i attach the search and datagrid each to their own panels in their own library?
i know i'm not doing a very good job explaining this .. espeically if you haven't used the dotnetmagic component.
any advice would be appreciated.

I guess I don't see what the problem is. .NET Magic doesn't care about where the content comes from. They are simply forms and can be in any assembly. When creating your docking manager and the content, instantiate the control from whatever library (either through Reflection or using assembly dependencies) and add it to the content. If you want to be able to refer to these controls directly instead of enumerating the content in a docking manager, then as you instantiate these various controls in any number of libraries, keep a collection (either local to the form that contains the docking manager, or some static collection that is globally accessible) or hashtable (same advice as for collections). We do something very similar in our application with no problem.
It's no different than creating a basic form with a default Button or DataGrid (for example). They are defined in the System.Windows.Forms assembly and your form isn't. The same is true for almost any language runtime in existence, for that matter.

Hello All.
I have this error in my application and I have no idea of what I'm doing wrong:
'ALINK: error AL1057: Executables cannot be localized, Culture should always be empty'
MSDN says about this 'An assembly is being created with /target:exe but /culture was specified. Assemblies in the .exe cannot have information in the Culture field'.
I can understand what this means. Anyone can explain to me ??
Thanks.
|
|
|
|

It means don't use the /culture switch! The main exes and dlls are always compiled into language neutral assemblies. You can control which language is neutral by using the System.Globalization.NeutralResourcesLanguageAttribute, an assembly-level attribute that you would typically put in your AssemblyInfo.cs file (although it can go anywhere, so long as it is appended with the assembly: prefix, like [assembly:NeutralResourcesLanguage("en-US")].
The /culture switch is used for satellite assemblies - assemblies that contain localized resources (in source form, these are ResX files). They contain no code. You can also create localized assemblies by using the AssemblyCultureAttribute, but these projects may not contain any code - only .ResX files (which are compiled to .resource files).
You can find out more in MSDN about satellite assemblies at http://msdn.microsoft.com/library/en-us/cpguide/html/cpconsatelliteassembliesside-by-sideexecution.asp[^] and localizing resources at http://msdn.microsoft.com/library/en-us/cpguide/html/cpcondesigningglobalapplications.asp[^].

Thanks for your response, but I'm still lost.
I don't know how to turn off the /culture switch.
The only thing I know about culture is that in the project I have a form in spanish and I want to translate it into English, so I put the Localizable property to true and then I selected into the languaje property English. Then I translated the form into English and after that I get the error.
Is this the cause of the error ? How can I turn off the /Culture swicth ?
Thanks in advance.
Bye.

Did you read the links I gave you? They discuss localization in great length. First, if you are authoring the original forms in Spanish and it is in that locale that all your code is contained, then use the NeutralResourcesLanguageAttribute and specify the appropriate culture. Second, try going back to the "default" culture (actually the neutral culture) in your form designer and compile again. VS.NET might thing that you're trying to compile the English satellite assembly as the primary assembly.
Second, show hidden files in your project. Look at the ResX files. If you use VS.NET's designers, these will be hidden under forms. If your form source file is named MyForm.cs, then you should have a MyForm.resx (the neutral language) and MyForm.en.resx or MyForm.en-US.resx.

I don't understand the "readOnly" parameter to PerformanceCounter constructor:
public PerformanceCounter(
string categoryName,
string counterName,
bool readOnly //QUESTION: If it's only readOnly, what's the use of the counter if you cannot update/increment it??
);
Thanks!

I want to copy data from one excel workbook to another. I have a range named 'MyRange' in workbook 1 on sheet 1. I want to copy this range to sheet 1 in workbook 2. More: I want to paste values and formats instead of formulas.
The VBA code looks like this:
**********
Application.Goto Reference:="MyRange"
Selection.Copy
Sheets("Sheet2").Select
Selection.PasteSpecial Paste:=xlPasteValues, .....
..
Application.CutCopyMode = False
**********
Any hints??

Hi All,
I am new to component development.
I want to create custom control to show selected objects in form of polygonal shape.
The objects are placed in separate panel on the same form.
Those should be dragged and arranged in required shape.
This is to show user how many euipments are present in factory.
On clicking any of this cirular control details of particular equipement are displayed.
Intially there should be four circular images placed in form of rhombus, and then when one more such object is dragged to the control display area, all 5 objects should be rearranged in form of pentagon.When one more object added they should look like hexagon.
Can you please suggest me any links where I can get infromation about creating such custom control or what steps should be taken to implement above functionality?
Thanks in advance.
Regards
Shailaja

You should check out GoDiagram. What you're talking about can be done but there's a lot of calculations and drawing. Plus, if you want to use shaped pictures on a canvas to represent different machines, you'll need to create an object model. GoDiagram has all that and at a good price. Just get GoDiagram with the layout model and it can do all this for you and is extensible.
Otherwise, you're going to have to do the math yourself. You can get the controls in a container (like the UserControl, or it if contains other controls you don't want positioned, you can use another Panel or something or filter the Controls collection as you enumerate the controls). For how many there are, you need to calculate the position. There's lots of different equations to help you, but you still have to code them. You also have to decide what the anchor point for each control is (i.e., one of the corners, the center, or other anchor point) and position the controls so that they don't overlap - resizing your virtual polygonal grid. That's not too bad since you can get the Size of each control and calculate the anchor point (probably good to have a separate method to do so and abstract that functionality so you don't have to include it all in one method).
When doing this, you have to take into account the relative position of each control. When calculating the anchor point, for instance, the Size of the control is for the control itself. The Location (a Point) is relative to its container. Because these two things are used for the Bounds property, you'll need to take that into account.

Let's say you have:
Location: WebService: COM+ component:
___________________________________________
ServerRoot WebServiceRoot COMPlusRoot
ServerA WebServiceA COMPlusA
ServerB WebServiceB COMPlusB
In WebSericeRoot (residing on ServerRoot):
[Transaction(TransactionOption.Required)]
[AutoComplete(true)]
[WebMethod(...)]
public void PlaceOrder(..)
{
WebServiceA service_a = new WebServiceA();
service_a.UpdateInventory(); //This will call COMPlusA residing on ServerA --> This will launch a new transaction!
WebServiceB service_b = new WebServiceB();
service_b.UpdateShipping(); //This will call COMPlusB residing on ServerB --> This too, will not participate in PlaceOrder's transaction and launches its own.
}
Even if UpdateInventory() and UpdateShipping() requires transaction, two new transaction will be started. In other words, COMPlusA and COMPlusB will start their own transaction because COMPlusA/COMPlusB and COMPlusRoot objects all resides in different server.
What are my options to implement distributed transaction across machine boundary. Do I need to roll my own transaction? Thanks.

I would like to be able to perform background work in my C# .net Windows Service if no mouse messages or key messages have be received for 10 minutes.
It involves downloading, uploading and processing, I would like to be able to tell if the computer has been idle from the user to a 10 minute period and then I would start these routines/processes.
I see how to do this with Forms with overriding the WinProc method, but I need Windows Messages for a Service, and I think the Forms WinProc method only gets events when the mouse is moved over top of it. I need Messages that occure anywhere within Windows/OS/Desktop.
Is there any Windows API methods to import or any idea how to do this?
Thanks in advance.

You'll need to use a system-wide hook DLL, which cannot be written from C# - you'll probably want to write it in C++. You can then use this from your C# application.

If you are using Windows 2000 or above, you can use the GetLastInputInfo API call. You get a structure with the tick count when the last input event happened.
|
|
|
|

Awesome, thanks alot Jeff, that is exaclty what I needed, i guess I can just call it in a seperate thread every minute or so. Thanks again
The GetLastInputInfo function retrieves the time of the last input event.
Syntax:
BOOL GetLastInputInfo( PLASTINPUTINFO plii );
Parameters:
plii - [out] - Pointer to a LASTINPUTINFO structure that receives the time of the last input event.
Return Value:
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero.
Remarks:
This is useful for input idle detection.
Function Information:
Header Declared in Winuser.h, include Windows.h
Import library User32.lib
Minimum operating systems Windows 2000
See Also:
Keyboard Input, LASTINPUTINFO

If I have a base class A and class B implments class A, how can I get access to class B from class A.
I want to use reflection to loop through the properties of class B in class A, but I need a reference to the object in order to do this.
Thanks for your help.
