i typed the full path but the code doesn't compile at all
this code is:
private void btn_create_Click(object sender, System.EventArgs e)
{
Microsoft.Office.Interop.Word.Application newApp = new Microsoft.Office.Interop.Word.Application();

l_status.Text+="object instantiated\n";

object Source="c:\\abc\\dat.doc";
object Target="c:\\abc\\Target.rtf";

object Unknown =Type.Missing;

// Source document open here
// Additional Parameters are not known so that are
// set as a missing type
newApp.Documents.Open(ref Source,ref Unknown,
ref Unknown,ref Unknown,ref Unknown,
ref Unknown,ref Unknown,ref Unknown,
ref Unknown,ref Unknown,ref Unknown,
ref Unknown,ref Unknown,ref Unknown,ref Unknown);
l_status.Text+="file opened\n";

// Specifying the format in which you want the output file
object format = Microsoft.Office.Interop.Word.WdSaveFormat.wdFormatRTF;

l_status.Text+="new format created";

//Changing the format of the document
newApp.ActiveDocument.SaveAs(ref Target,ref format,
ref Unknown,ref Unknown,ref Unknown,
ref Unknown,ref Unknown,ref Unknown,
ref Unknown,ref Unknown,ref Unknown,
ref Unknown,ref Unknown,ref Unknown,
ref Unknown,ref Unknown);

l_status.Text+="new file saved \n";

// for closing the application
newApp.Quit(ref Unknown,ref Unknown,ref Unknown);

l_status.Text+="object closed \n";
}

===============================================
the error message is :

An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in code_container.exe

Additional information: The server threw an exception.

Indicates that the code has compiled. You have a runtime error.

What line did this happen on?

I suspect this is where the exception was CAUGHT. Not where it was generated/thrown.

static void Main() 
{
try
{
Application.Run(new MainForm());
}
catch(Exception e)
{
Debug.WriteLine(e.Message);
Debug.WriteLine(e.StackTrace);
}
}

Will write to the output the location that the error was generated. This will help with solving the problem.

i used try catch statements and the erorr is comming from this line:

plz keep with me and this will be apreciated
thnx another time

Colin, note that putting a try-catch around Application.Run only works when an exception causes the application message pump to terminate. This is usually not the case. The try-catch should be as local to the problem as possible (like in the original poster's code to create the Word app and open the document). You can also handle the AppDomain.UnhandledException event.

True, like happened here. I realise that the try...catch would be better placed else where but trying to help quickly I figured it was easiest to put round the Application.Run.

Well, it looks like your code was copied from the documentation. So I don't see much difference between that and MSDN. Are you using a WordProject?

I'm using VS2003 and Office 2003 (So it might be an office thing) Anyway - I've emailed you the skeleton of the WordProject - it might provide clues to help with your problem. (Its easy for me because it does all the hard work getting everything integrated - You may have to change the project properties because the startup command line may be different in your case)

Properties inspector style control

Hi,

Does anyone know if the .NET framework has any support for easily creating property inspector style windows? Had a quick look through the available Windows Forms controls and components, but couldn't see anything of interest. Anyone any suggestions?

Cheers
Richard

You mean like the PropertyGrid? This (or at least a similar control) is what VS.NET uses and it makes full use of the classes in System.ComponentModel so you can make properties with TypeConverters and editors, as well as control the categories, descriptions, visibility, and other attributes using the attributes in System.ComponentModel. If you don't see the PropertyGrid in your toolbox, right-click on the toolbox and select "Customize toolbox". You'll find the PropertyGrid in there (it's in the System.Windows.Forms namespace).

You should take a look at Managed DirectX 9 (http://msdn.microsoft.com/directx[^]). The managed classes are written from the ground up and are much easier to use (still not a trivial thing to work with, though, so read the documentation!) and offer many features like that.

Otherwise, you'd have to create an interop assembly for something like the Windows Media Player, which should have a method to make it display full-screen (hint, download the small Windows Media Player SDK and see the documentation for player.fullScreen boolean property. This might also be in the MSDN Online Library).

How keep areference of string

Eric Lacroix8-Dec-03 17:53

Hi CodeProject member,

I got the fallowing code:

...
protected delegate bool ValidatorHanlder(object obj, ref string PropertieName, ref string ErrorNumber, ref string ErrorMessage);

PropertiesList = new Hashtable();
PropertiesList(StringProperty, new ValidatorHanlder(ZipCodeValidator));

public string StringProperty
{
get
{
return mStringProperty;
}
set
{
mStringProperty = value;
}
}
...

It is possible to reference the string by storing is pointer and not is value when added to the hashtable ? and if ZipCodeValidator is declare as static do i need to do a new pointer allocation on it?

(define Email (lambda ()
elacroix@devmesh.com))
Im not a church numeral im a free variable

Heath Stewart8-Dec-03 18:28

System.String is a reference type already. If you try to modify the string, however, you will get the modified copy because strings are immutable. If you are trying to do this, use the System.Text.StringBuilder instead.

ZipCodeValidator is just a method. A delegate is like a managed function pointer. It doesn't care if the method is static or instance-based. You still need to use the new operator on the delegate, though.

Creating a Table (Class Scheduler)

I am attempting to develop an algorithm that will compare data in mutiple tables(e.g. Professors, Available Classes, Curriculum, Past Schedule) and create a new table that will be a become a class schedule for a department at a college. How can I create a new table in C#, without manipulating the database with MS Access itself.

First of all, C# is only a language that targets the CLR. It compiles to IL just like any other .NET language.

That being said, you can't do this in the .NET base class library (BCL). You can use ADO.NET to invoke SQL commands on many different data sources, but there is nothing to help you create tables, views, etc.

Depending on what database you are using, you can create COM interop assemblies to manipulate the database. You can interop DDL for Access and SQL DMO for SQL Server. I'm sure other major RDBMS's have similar libraries - at least those built with Windows technologies in mind.

This has been covered quite a bit in the last couple days so please search the comments (click Search Comments above) for this forum.

Accessing variables from the code behind page

I'm trying to pass variables from my main.aspx page to the web user control page. I have a flash application that reads the variables and based on that displays a certain item that's embedded in the web user control page. The variable that I created needs to be on the main.aspx page, so when flash opens up it can tell which page it's on. It looks something like this:

This is on the control.ascx page, the problem with this is that it has to be on the same aspx page.

<param name="FlashVars" value="navStatus=<%=pageStatus()%>" />

This is on the main.aspx.cs page

public string pageStatus()
{
return "home";
}

I have also accomplished my goal by using session variables, but I don't want to use them. Is there is any way to inheret the function that's on the main.aspx or pass somekind of global variable to where it can be accessed anywhere. Remember that the variable needs to be in the main.aspx page, it can't be in a class library or component.

Thanks,
Jaime C

Do a Type-check and cast it. From the UserControl:

private void Page_Load(object sender, EventArgs e)
{
  string value = null;
  if (Page is main) // Where "main" is the Type for main.aspx.cs class
    value = ((main)Page).pageStatus();
}
