Re: WCF - OperationContract Generic Argument

First understand how to construct a generic method[^]

I don't believe it is possible to use a generic method with WCF

1. There is WCF forum.
2. Post the error message as well.

Really I don't understand you. You say "You should also have asked this in the WCF forum as it is specific to that topic, not c# in general ".

Are you kidding?

Sorry again...

What don't you understand? The question was WCF related not a general C# question and as such should have been placed there. However, since you had received answers here it should have been left here.

I agree with the OP here. This is a WCF related post hence belongs to that forum. When the user does that, you cannot blame for reposting.

I'm new to C# coming from C/C++, hence the question. I'm receiving data from a tcp connection into a byte array. Then I want to send a portion of the contents on to another tcp connection. How do I do that? For example, I get 50 bytes but want to send out only from byte 25 to byte 50. How would I access and copy this "subarray" into another array?
Thanks

Array.Copy lets you copy arrays (full or segments) from one to another.

Textbox text scrunched

Dear Sirs,

I'm using a textbox control to display some text and the text on the right is appearing scrunched. It looks as though it displays the first x distance (I'm pretty sure it looks to be measured in distance, not characters) normally, and then squishes the characters (horizontally) taking out all character spacing so that they're not overlapping, but touching. Perhaps I'll give you a picture...I can't see how to insert one into the post, so I'll give you a link to my SkiDrive. My sky-drive photo. As you can see from the photo, the text is scrunched on one row, but not two rows down!! If you can tell me how to fix this, let me know. THANKS!!

In Christ,

one of three three things:

If you are "creating your own" text box.. I really recomend against it.. use the Rich text or normal text box... but if you are you are using GDI+ to do the drawing in which case you should be using Graphics.DrawString()... not cycling threw your characters.. this looks like what the problem is.. remember that if your want to use this approach that you will need to add in the letter padding manually (X+=3;).

Now if that is not the case:

You may have inadvertently set a flag somewhere for your first string and then re initialized(clearing the flag) for the subsequent strings.

Lastly if you are using different fonts, or units of measure you may get a squinched string...

But you could post some code.. that might help.

Dear Mr. ely_bob,

Thanks for your response! You know what...now that you mention it, It might be using GDI+ that the text is being drawn. I just realized that the TextBox control is used for EDITING the value, not displaying it! I keep forgetting that it's programmed that way. I'll look at it. So you think that maybe what's happenning is that the x += 2; is not persisting; okay, I'll check it out. Thanks again.

[====EDIT====]

It looks like this is the code used to draw the strings:

context.Graphics.DrawString(label, _font, _brush, clipRect, _format);

Yup...just checked, and I see where it drew my string. So...let's see.
the arguments

label = "0.0\0.0\-25.0\0.0\0.0\-25.0\0.0\0.0\-25.0\0.0\0.0\-25.0\0.0\0.0\-25.0 "
_font = {[Font: Name=Microsoft Sans Serif, Size=8.25, Units=3, GdiCharSet=0, GdiVerticalFont=False]}
_brush = {System.Drawing.SolidBrush}
clipRect = {X=418,Y=768,Width=338,Height=16}
_format = {[StringFormat, FormatFlags=FitBlackBox, NoWrap, NoClip]}

Now, I'm reading about the format.FitBlackBox property, it says
"...By default, characters are repositioned to avoid any overhang." I would guess that this is the effect I'm complaining about, but after changing that, I still have the effect. Let me know what you think.

In Christ,

I f you take a look at C# File Browser[^] you will see that it contains a TreeView that displays folders, so studying the code might help you to get part way to your objective.

If that is a bit difficult to understand (you do say that you are a C# newbie) this[^] might be simpler.

For getting images to represent your files, you might also find Get Registered File Types and Their Associated Icons in C#[^] useful.

But your original question referred to checking for the existence of the folders and *.mp3s. What better way to do that than by walking the directory structure and adding only folders that contain files of interest (and the files themselves of course).

If you are doing something else, perhaps if you can explain what your app is trying to do and how you would like it to work, someone might be able to help you. Smile | :)
