If you are using the Office Interop, then no it will not work. This is why I never use the office Interop. If you use the ole db provider for the db then it will work.

I am using the Oledb provider, do you have another idea or advise.
Thank you!

Hi,
I have been looking to find a way to draw lines onto a richtextbox control but have not been able to find anything on the web (or here). To clarify, the specific application I am working on has a requirement that the GUI looks like a piece of lined paper (i.e. I do not just want to put a bitmap into my control) which the user can type onto.
Solutions I have looked at so far include (but are not limited to):
1) Subclass richtextbox and override OnPaint to draw lines after calling base.OnPaint -> This does not work which seems to be because of the way MS implemented the base method, but I don't want to have to rewrite the entire drawing of the control if I can help it
2) Put a 50% transparent form over the top of the rtb and draw lines onto it -> I found this idea somewhere but it seems very messy, and makes it trickier to type into the rtb at the same time
3) Copy a row of - or _ characters to the clipboard and paste into the rtb -> User typing then messes up the look
4) Insert bitmap images into the rtb -> doesn't work for same reasons as 3
5) Place an rtb onto a user control or form and draw lines on the form in correct positions -> Lines get drawn underneath the control
6) Use BitBlt directly to draw on top of the control -> I haven't tried this one yet, but I would rather avoid using Interop if I can
Given that these solutions do not work (at least as far as I can tell), can anybody suggest any other approach or any references I might look at?
Thanks in advance,
Chris

I don't know how to do this with the WinForms RichTextBox, but have you looked at using the WPF RichTextBox? It's so much more powerful and flexible than that WinForms one, I suspect it would be relatively easy to do there.

I hadn't heard of WPF until I just read your post so I have just looked it up - am I correct in thinking this is a .Net 3 feature? I haven't upgraded from 2 yet...perhaps it's time to get around to it! Anyway I will look into this a bit. Thanks for the reply 
Does anybody have any other suggestions (.Net 2 or 3)?
Thanks,
Chris

Hi,
I haven't done this, but maybe you can:
1. use a Panel, and draw lines on it with Graphics.DrawLine
2. put a RichTextBox on top of it, and set its BackColor to transparant.

When setting a RichTextBox BackColor to transparent I get an error "Control does not support transparent background colors."
The code I was using was: richTextBox1.BackColor = Color.FromArgb(100, Color.White);
Unless I did something wrong with the way I did this, looks like this idea is out. I've tried playing with transparent controls before and I'm always dissapointed that there deosn't seem to be more native support in this area!
Thanks for the suggestion though!

WPF (Windows Presentation Foundation) is the next generation UI toolkit. It provides rich support for documents, animation, imaging, video and other nice things. It is .NET 3, yes.

Hi all
I'm calling a non-.net web service and getting myself confused.
The object that is being created from the WSDL includes and out_msg, which is basically the return value. Within out_msg, there is an array of deal objects, however it's not a true array as I can't enumerate it - how do I convert this return value in to something useful (XML, generic list, well, anything really!).
/// <remarks>
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Xml", "2.0.50727.42")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType=true)]
public partial class out_msg {
private object itemField;
/// <remarks>
[System.Xml.Serialization.XmlElementAttribute("deals", typeof(deal[]))]
[System.Xml.Serialization.XmlElementAttribute("errors", typeof(out_msgErrors))]
public object Item {
get {
return this.itemField;
}
set {
this.itemField = value;
}
}
}
Thanks
Ben

Look in the debugger the type, and cast it...
xacc.ide
The rule of three: "The first time you notice something that might repeat, don't generalize it. The second time the situation occurs, develop in a similar fashion -- possibly even copy/paste -- but don't generalize yet. On the third time, look to generalize the approach."

Thanks Leppie - think I was having a Friday brain melt-down. Had already tried casting to an ArrayList and a generic list of deals objects.
But, of course, it was just a good old fashioned array.
Cheers
Ben

You can tweak and change the xsd file to suit your needs. The xml serializer is very leniant. Just do your best to make it match the input schema.

But not forgiving! Ever had to debug that lame generic XML serialization exceptions? You have to drill down into about 45 inner exceptions to get to the root of the cause

Hi all...
It's not a proper C# question, but my app is developped in C# and I didn't find a better place to post...
I finally joined the moment to deploy my App.... Easy: everything works fine! But I'd like to have the install process in 3 different languages, and I couldn't figure out where and how can I do this!
Any suggestion? Tnx a lot!

I thought that could be done in Visual Studio Setup project...
I don't like so much the SDK... but let's try anyway!
Tnx for the answer!!!!

Does anyone know places where I can learn more about visuals for C#, like, blurring, softening and things like that? Also, is there a way to set events for graphics you've drawn, like click and hold? Finally, are there any sounds that are already on the computer besides system sounds to use? Thanks in advance.

That depends on if you are talking about graphics, windows forms or WPF.

Graphics that you have drawn are just differently coloured pixels, they can't handle events. If you want evens, you need controls.

Ah... I mean graphics. Well, I had an idea where you could grab a circle by clicking and holding and move it, and release the click to drop it... It's for another simple game I thought I could achieve...

Also, is there any way to make lines in an app anti-aliased?

Yes. If you are drawing in a graphics container, you can set the SmoothingMode to AntiAlias. This will not affect the text, but will affect lines in the container. Check out the MSDN documentation for Graphics.SmoothingMode.

don't be surprised if you get the same results you always got.

Where is smoothingmode? Is it an extra using statement? Also, do you know the code to, while the mouse is clicked over a picturebox, that you can drag it around? I checked out the drag and drop events, but I don't see... Thanks, tough.
