Sounds like you need to investigate the system tables. Getting a list of tables and their columsn from sql server is easy enough - check out the information_schema views. Fromthis you should be able to generate your search.

By the defenition of "..run my applications..", do you mean that you start the program, open/read file, then close the program? If your not actually closing this program, it sounds like your not disposing the file handle properly.

I've used up all my sick days, so today I'm calling in dead.

How to embed another executable into a C# Window Form?

Hi,

I am developing a C# application which launches a couple of other applications (non-C#). I can use the System.Diagnostics.Process class to start the child applications, but how can I embed these child applications into my Window forms and dock them at fixed positions in my MMI so that the whole thing looks like a single application? I dunno whether what I am asking makes sense, it's something like XWindows or Remote Desktop, where the remote application runs inside my own C# Form... Any suggestions? Thanks in advance. Smile | :)

You can make a hosted application window show up in a Panel or other container control in your form but you cannot make it look like it is an integral part of your application. You have no control over how the hsoted app's window is rendered. Docking is pretty much just moving the hosted window so it's up against the side of yours, but you can't stop the user from just grabbing the title bar and moving it.

You will need to look into the Process class' MainWindowHandle property and the Win32 function SetParent[^].

Keep in mind, that any child windows that the hosted app shows could very well show up outside your application window. Also, some applications do not like having their main window hosted by another parent, but most will. You could run into rendering problems or other strange issues.

Creating a timeline editor

For my application, I really need a timeline editor (a keyframe-like editor like can be found in Flash and Director and movie and sound editing software).

I'm guessing something like this has already been implemented somewhere. Does anybody know of anything that could be harvested? If not, does anyone know of a tutorial that suggests how to create one?

Thanks!

Using XMLDocument or XMLTextWriter.

Load it to XMLDocument instance and work with RemoveChild[^] method.

Either use XPath or Linq-XML.

Specific XML Format

Hi All,

In my current C# app I need to write what seems to be a non-standard format XML file to be loaded into a very picky application.

I'm limited to this kind of format:

<rootnode name="preset #1" attribute1="" attribute2="">
    <childnode index="0" />
</rootnode>

If there are any namespace (like xmlns Smile | :)

the app won't load the file, if there is an encoding="" the app wont load the file also.

And to top it off the file needs to use UNIX ANSI not Windows ...

Does anyone have any ideas or info/links on how to achieve this?

Thanks,

Jammer

On the other hand, there appears to be very little data, so I bet it loads real fast.

Ummmm... Your code ain't showin' up. Try escaping all of your pointy brackets, and then put it in a pre tag.

Yes, but I wanted him to do it. Big Grin | :-D

But while I'm here... I see nothing wrong with that XML; it seems well-formed.
The worst thing I see is the #, which might be better off escaped/encoded.

I generally use an XmlDocument to hold XML and write it to a file with code like:

WriterSettings = new System.Xml.XmlWriterSettings() ;
WriterSettings.Indent = true ;
WriterSettings.Encoding = System.Text.Encoding.UTF8 ;
WriterSettings.OmitXmlDeclaration = true ;
WriterSettings.CheckCharacters = false ;
 
using 
( 
    System.Xml.XmlWriter writer 
= 
    System.Xml.XmlWriter.Create 
    ( 
        File
    , 
        WriterSettings
    )
)
{
    Doc.WriteTo ( writer ) ;
}

You may need to tweak WriterSettings.NewLineChars and WriterSettings.Encoding.
