For some reason, only the part of the table name up to the space is recognised. Do I need to escape the space in a special way or try some other method? Thanks. ...code.... String sTable = "Table space". dataAdapter.File(dataSet,sTable); //exception here...., tries to load "Table" "Ergo huffabo et puffabo et tuam domum inflabo" ait magnus malus lupus. Re: Space in table name problem Christian Graus4-Jul-04 14:08 Christian Graus 4-Jul-04 14:08  Spaces in database object names are a terrible idea, use _ in future. For now, I believe that wrapping the name in square brackets will fix the problem. I know that works for reserved names. If I am wrong, try single quotes, but that seems a lot less likely to me.

I've tried wrapping it in square brackets, but it still throws an exception and seems to ignore the part of the name after the space, also does this if I replace the space with an underscore, quite weird.

The _ will only work if the table is named that way to start with, you can't use one for the other The [] is generally a good way to show SQL what you mean when it's not clear, for example if you name a table Index, it won't work without the [] to show that the reserved word is meant as a name.

I have added a reference of the Microsoft Word 11.0 Object library to my project. Thing is that the below line of code is causing an error "The type or namespace name 'Word' could not be found (are you missing a using directive or an assembly reference?)" private Word.ApplicationClass WordApp = new Word.ApplicationClass(); This is the main line where the Word document creation starts. I dont get this error when using Microsoft Word 9.0 Object library (Word 2000).. but the requirement is for Word 2003 automation. I am not using Visual Tools for Office 2003. Is there any other way to create word 2003 documents? Thanks in advance sundancer Re: Word 2003 & C# Heath Stewart5-Jul-04 5:51 Heath Stewart 5-Jul-04 5:51  You should always use the PIAs (Primary Interop Assemblies) for Office when possible. Visual Tools for Office 2003 (.NET programming support comes on the Office 2003 Professional CD) and the downloadable Office XP PIAs are what you should use. In fact, if you want to support both Office XP and 2003, use the Office XP PIAs which you can download from MSDN[^]. Typelibs are typically forward-compatible but not always backward compatible. In fact, for most basic functionality even typelibs from Office 97 should support 97, 2000, XP (2002) and 2003 versions of Office products. In any case, though, the problem is that you aren't referencing the namespace correctly. The namespace is not simply "Word". It's most likely "Microsoft.Office.Interop.Word". At the top of your source file along with all the other using statements, type using then hit Alt+J to display the namespaces.   Microsoft MVP, Visual C# My Articles noob - using WinConsole - need to compile insurgentpyro4-Jul-04 6:19 insurgentpyro 4-Jul-04 6:19  i recently downloaded the source code for the WinConsole, by Wesner Moise.

Re: noob - using WinConsole - need to compile Mike Dimmick4-Jul-04 12:06 Mike Dimmick 4-Jul-04 12:06  It looks like the download contains essentially two parts: the WinConsole class and the ConsoleWriter helper class to help redirect trace output, which are implemented in WinConsole.cs and ConsoleWriter.cs respectively, and a test program implemented in Main.cs with assembly data in AssemblyInfo.cs. To build the test program, either use Visual Studio to open the WinConsole.csproj, or build on the command line like so: csc /t:winexe /win32icon:app.ico assemblyinfo.cs ConsoleWriter.cs Main.cs WinConsole.cs To use in your own application, you can either include the source files in your project, or you could build WinConsole as a DLL: csc /t:library /out:WinConsole.dll WinConsole.cs ConsoleWriter.cs Stability.

The application will read and write its data from/to an XML file (multiple versions must be supported, at least for reading). The XML structure is not very "relational", it is more a document (in the sense of a Word document) than a database (tablular data). I'm coming from the Java world, and used a ValueModel style data binding with great success. More details about the ValueModel data binding style can be found at http://c2.com/ppr/vmodels.html and http://c2.com/cgi/wiki?ModelViewControllerHistory. With a ValueModel data binding, i would read the XML File in an object, put that in a ValueHolder, and would wire all widgets with AspectAdapters, SelectionInList, ... This would provide me with a bi-directional binding, and usinge the BufferedValueHolder i would even get a buffering for free. My question to the WinForms gurus: is the DataView data binding flexible enough, even if my data is more a document than a table? can i bind a text field bi-directional to a property of an arbitrary object? does the DataView data binding work when the widgets are on different forms? what's hard with DataView data binding, what style of binding requirements should be avoided?

No, it is not. A DataView is created over a DataTable, which is a class used within a DataSet (any of which don't require you to use a DataView, but they will be more limited in functionality since the DataView supports filtering, sorting, etc.). A DataSet XML schema consists of 2- to 3-level elements (tabular data, as you said). zet wrote: can i bind a text field bi-directional to a property of an arbitrary object? Yes; see the PropertyManager class in the .NET Framework SDK for more information. This is used in the same manner as the CurrencyManager class, which are both derivatices of the BindingManagerBase which is used by the Control.BindingContext property. Use the Control.DataBindings collection property to add bindings to objects (like another TextBox) for properties (like the Text property of your two TextBoxes). zet wrote: does the DataView data binding work when the widgets are on different forms? A DataView is simply a class. So long as the instance is accessible on different forms, the controls can bind to them. The import thing to realize is that a BindingContext must bind to the exact same object and member name (like a DataSet and one of its table names, or just the DataTable itself). -- There is nothing really provided in the .NET BCL (base class library) that provides the sort of binding you're asking for, but that's not to say it isn't possible (anything is possible when comparing Java and .NET, it's just that the JRE contains/lacks some stuff that .NET doesn't/does have). This also sounds quite a bit like the MVC pattern (Model-View-Controller), or at least it would fit. CodeProject has several good articles about MVC, including Declarative Programming Of The MVC Pattern Within The Context Of DataBinding[^].   Microsoft MVP, Visual C# My Articles C# grid control - headers Andy H4-Jul-04 0:06 Andy H 4-Jul-04 0:06  I have a project that was written in VB6 and which I need to re-design in C#. It uses a number of MSHFlexGrids that have had the header height expanded to fit two lines of text. Is there a grid control available in C# that will allow me to change the header width? Re: C# grid control - headers Heath Stewart5-Jul-04 6:04 Heath Stewart 5-Jul-04 6:04  Not in the base class library (BCL), no. The DataGrid is the closest thing to the FlexGrid component, but does not expose APIs for owner-drawing the headers. I suggest you take a look at some third-part controls like XtraGrid[^]. Many other third-party controls are available to use, but I've used this one and it works well.   Microsoft MVP, Visual C# My Articles D3DXSaveSurfaceToFile() is nowhere to be found. 3-Jul-04 18:36 3-Jul-04 18:36  This is really starting to piss me off.

You need to P/Invoke it. Besides, C# doesn't even support functions - only methods (functions defined on classes). Looking at the Managed Languages documentation for DirectX 9.0 may help. For example, the SurfaceLoader has a method, Save, which is what you want. This saves a surface to a file for various different image formats. Remember that C# is a true object-oriented language (.NET code can contain functions, but the C# language does not support it).   Microsoft MVP, Visual C# My Articles Re: D3DXSaveSurfaceToFile() is nowhere to be found.

I have installed the setup and when I try to start my service from the Services in the Administrative tools in control panel, I get the following error: JIT Debugging failed with the following error: Access is denied. JIT Debugging was initiated by the user account 'NT AUTHORITY\LOCAL SERVICE'. Please give me any clues how to debug the JIT error. Thank you. Re: JIT Debugging Heath Stewart5-Jul-04 6:15 Heath Stewart 5-Jul-04 6:15  You need to grant the NT AUTHORITY\LOCAL SERVICE user debug privileges. That's actually a very bad idea, though. Anyone with debugging privileges can do quite a few things to your system that would go unchecked (like overwriting memory addresses without taking advantage of security holes). Instead, while debugging your service you should run it as you (which, presumably, already has debugging privileges). To give NT AUTHORITY\LOCAL SERVICE debugging privileges or to make sure you have them (if you can debug, you have them), use the local security policy editor in Control Panel->Administrative Tools->Local Security Policy. Drill down to Local Policies->User Rights Assignment. Note that if you're in a domain, the domain administrator might have set these and taken away your ability to change them. Again, giving NT AUTHORITY\LOCAL SERVICE debug privileges is a bad idea - it is a security hole. Just change the login credentials for your service to you for the time being to find the problem. Do run it as NT AUTHORITY\LOCAL SERVICE to make sure everything works once yo've figured out the problem, however.   Microsoft MVP, Visual C# My Articles why i can't run a c# app on win 2k without .net framework installed? jl_araya3-Jul-04 12:32 jl_araya 3-Jul-04 12:32  hi guys! ..eeeh only this, i can't run a c# app on a pc with win 2k but without .NET framework installed. why this... ? can i do something? thanx!!
