I am trying to get a structure returned from a web service and am having a hell of a time.
I can consume the service through IE and get back my XML package just fine, but when I try the same thing in a Windows Forms client application I get an error that says there is an error in the xml file.
I can return simple types like Booleans and stuff all day in the client but not a publicly declare structure.

Ok, I figured out the problem... Some of my structure members were strings containing text that was encrypted and the chars returned by the encryption function must not be XML friendly.
Any ideas how to escape this?

Have you tried wrapping the non-XML-friendly chars in a CDATA section?
<test>
<![CDATA[Offending data]]>
</test>
That might work, but then again if they are chars it might not and you will have to use a text encoder (.NET has plenty) to encode them to UTF8 or whatever your XML is set to. I think. Not my forte (encoding.)

I might try that latter, but now I have another issue. I am trying to eturn an ArryList of structures and am getitng told that I can't do that because the structure definition does not get included in the wsdl file.
ARG! Who was it that said web services would solve all my problems?

I am no expert on this, but one thing comes to mind: Have you tried serialising out the ArrayList structure to XML and then returning that? Apologies if that is exactly what you are doing or if that is not what you need at all.
Also maybe this article may have something for you.[^]

I have the horrible feeling that I have royally screwed myself.
It does not seem possible to create a transparent GIF in .NET, even though the methods are all there.
http://www.dotnet247.com/247reference/msgs/9/47813.aspx[^]
http://www.dotnet247.com/247reference/msgs/9/47038.aspx[^]
Both seem to indicate it cannot be done (the first one mentions a way, but then you can't use a Graphics object on it. Which is exactly what I need in the first place, doh.)
Anyone found a way? Anyone can tell me categorically that I am screwed?
I tried to save as PNG (PNG has alpha blending) but the background came out very strange indeed.

At least, this part I can explain why, the problem is not in .NET:

While yes IE does have a problem with PNGs it can be easily "solved" by saving your PNGs as 8bit and not 24 or 32bit. Not always ideal but in my case I saw it as the solution.
Now I just have to figure out how to convert a 32bit PNG made by .NET into a 8bit PNG, using .NET of course (someone said "But Paul, just use Paint Shop Pro to convert!", umm thanks but the graphics are being made on the fly and there is about 4000 of them.)
I can make a transparent PNG in .NET (opened the result in Fireworks and it was transparent, same with Mozilla) but this conversion stuff has me getting a headache.
Thanks for the link again, I had lost that one and was looking for it. The DIV DX filter trick is not ideal, but I may have to use it (thankfully the project only has to work on IE 5 and up)

Yes I can I looked into many ways for those web boxes. Even PNG has a problem rendering a touch too dark...or IE renders a touch to light.

Thanks leppie. I actually went straight to your web-boxes project to see how you had done the curves and transparency.
I have managed to make a 32bit transparent PNG in .NET, no problem there except of course the transparency does not show in IE. What one has to do is to convert that 32bit PNG to an 8bit PNG, then PNG transparency works in IE. So, guru, how do I do that damned conversion?

There are at least two ways. But this remains theory until practice shows it works.
The first way to achieve 32bit --> 8bit color reduction is to explicitely set an encoder attribute when you are saving your file. This code snippet[^] shows how to proceed. Of course, it is going to work if the built-in GDI+ PNG encoder directly supports paletted formats such as 8bpp.
The other way is to explicitely convert the current image into a palettized one. There is a GDI (not GDI+) function which does that job : it's CreateHalftonePalette. And it has to be used in conjunction with other functions to make sure it is applied on the image. More info in this code snippet[^]. (this sample uses GetHalftonePalette instead of CreateHalftonePalette, which might be enough to do the job, in fact).

more or less exactly ? about 12, 18 months ?
I'm starting to see some job posting that look for experienced C# and other .net framework experience.
Maybe I'll send in my resume, just to see if knowing about C# and the .net framework is enough experience form them .
Max.

- either it's a fake aimed to tease you. I happen to have been seduced by this approach, and in the end, I am still asked to use VB, not .NET. F*** the employers.
- or the required skills have been randomly filled by a HR person who doesn't know a sh*t about IT.
- or it's a way to make sure that you can start developing C#-stuff the first day you enter the job.
.NET is out since Feb 2002. The first beta was out 1 year before.
.NET is still in an evangelization phasis. 4/5 years are required before it becomes a massive standard. Besides that, I can see the point of using .NET for ASP.NET portals, but honestly I don't see the point with desktop apps : slow, memory hungry, limited in features since you end up doing interop for practically anything (like the Declare statement in VB), etc.

I got my first glimpse of .NET and VS.NET in July 2000 at the TechEd in Amsterdam. I think they sent the first useable .NET tools to me about September/October that year. I remember writing a few things in C# before the end of 2000.

I've been using C# off and on since the Summer of 2000. Of course, everything changed with each new beta release, but that's besides the point.
On a related note, I was looking for a job last year and the employer all but called me a liar when I listed my C#/.NET experience at around one year (so I'm modest). They said "how could you have that kind of experience when Microsoft just released the product last month (this was in 2002)". I explained about the beta period but I don't think they believed me.
I guess I should throw away all the code I wrote from 2000 to 2002 huh? Since C# didn't really exists before 2002 - right?

seems, that nobody can help me 
i have 3 main problems, i just cant solve, although they sound easy:
1. I cant change the icon of the addin button.(i always have the default button, a smiley)
(sounds like a easy problem,he? TRY IT!!!,change it to a custom icon!)
2. I cant assign a default shortcut, i tried the following but it didnt worked(it compiles, but it does not assign the key)
//in the onconnection method:
SAFEARRAY arrSafe;
arrSafe.fFeatures =FADF_BSTR;
arrSafe.cbElements =35; //maby not necessary
arrSafe.cDims = 1; //maby not necessary
BSTR bstrShortCut =A2BSTR("Global::alt-s");
arrSafe.pvData = bstrShortCut;
VARIANT var1;
var1.vt = VT_ARRAY;
var1.parray = &arrSafe;
pCreatedCommand->put_Bindings(var1);
3. I would like to install my addins(the buttons) by default in a menu next to "Tools" which is called "MyAddins". how can i do this??? (i can manually make a new menu (Tools->customize,etc..) and then install my addin in there automatically (IfFailGoCheck(pCommandBars->get_Item(CComVariant(L"MyAddins"), &pMenuBarCommandBar), pMenuBarCommandBar);
but i cant make this "MyAddins" Menue automatically by code!!

Hello,
How to validate a xml document against a dtd when no dtd reference is actually in the xml document.
Thanks,

I will let you find out the details but very simply you use the XML classes in the .NET Framework. Load up your XML document and there is a property/method to assign a DTD/XSD to the XML file and then you can validate it.
Go through those classes. They have virtually everything you will need and all very self explanatory.

Dear experts,
Does anyone know how to get access to the text box control that is displayed underneath icons on the Windows desktop. I want to re-use this text box in my own application as it has the "growth" behaviour that I urgently need. I need a text box that will grow in height as more text is added to it.
PLEASE HELP ME! Thanks in advance for your assistance.
Benjamin
