Hi All,
I'm having a problem with (as you could probably tell from the title) javascript in the webbrowser control. On the page I'm trying to get working there are some text boxes that should automatically fill in when you type a few characters, but for some reason they're not working. If I try the page in IE they work fine. I didn't create the page I'm just using it. Any ideas as to why the javascript wouldn't be working with the browser control? Is there a setting I need to make?
Many thanks in advance.

No. However some functions do not work in a web browser control. There is no documented list of such unsupported functions.

Do you see any error message box ?
And while you are in a stand-alone Internet Explorer instance, where it seems to work fine, do you have a yellow icon in the status bar (which signals javascript errors) ?

First, thanks for the reply.

No, there is no error box that pops up.

I just checked an no there is no error icon. Something strange that I noticed last night though. On the site, if you type something incorrect into the box, when it loses focus it deletes the text. Now, in my program that part works (I assume it's done in javascript as well) the only thing that doesn't appear to be working in the autocomplete thing that it does.
It's really baffling and grating on my nerves. Any ideas or help would be very much appreciated.

It looks like an issue originated by a rather specific combination of javascript source code. I am afraid you'll have to post portions of it.

The best idea I can come across is to tell you to post on the right forum. The issue is not related to C#.

Here's a good one ...
Assembly C (.DLL) exposes (among other things) a number of type converters.
Assembly B (.DLL) exposes a derived form containing a PropertyGrid that 'uses' C's type converters.
Assembly B therefore has a static project reference to C.
Assembly A (.EXE) dynamically loads assembly B and displays B's form as a child of A's main form.
The problem is, the PropertyGrid 'loses' the type converters and the associated properties appear as greyed out text (the namespace qualified type name to be exact). I assume that internally PropertyGrid uses reflection to create C's type converter instances but C is 'invisible'.
The problem is fixed by adding a reference to C in project A but this is undesirable since C may not actually exist for a particular installation.
Loading C dynamically from A (tried both Assembly.LoadFrom and AppDomain.Load) is successful - AppDomain.GetAssemblies reports C as loaded but the PropertyGrid still falls down.
Any ideas ?
Thanks in advance

try to use attributes
<br />
[Designer( "UtilityLibrary.Designers.WizardFormDesigner, UtilityLibrary.Designers, Version=1.0.4.0, Culture=neutral, PublicKeyToken=fe06e967d3cf723d" )]<br />
In bold is a sumbolic name of assembly. By such name Framework can find and load needed assembly. In your case look for Convert attributes:
<br />
[ Category( "Appearance" ), <br />
DefaultValue( -1 ),<br />
Description( "GET/SET toolbar item image from Image List" ),<br />
Editor("System.Windows.Forms.Design.ImageIndexEditor, System.Design, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a", typeof(System.Drawing.Design.UITypeEditor)),<br />
TypeConverter( "System.Windows.Forms.ImageIndexConverter" ) ]<br />
Such knowladge can help 
Good Luck

Hi , when and how are .net attribs activated?
is it at compiletime?
if i create my own attrib and apply it to a class like this:
[MyAttrib("tjoflöjt")]
public class{
}
is the text "tjoflöjt" injected into the assembly somehow when compiling ,
or is an instance of my "MyAttrib" class created once the assembly is loaded into memmory?
attribs like "AssemblyXXX" can stop the compiler and notify the user on various things like ".snk file not found" , is it possible to do the same thing with my own attribs?

I don't know the answer but I can point you to a resource for an example.Go to www.wrox.com and download in "Professionall C#" book.In one of its chapters there are good examples for Active Directory.Hope it helps.

I need to write a module for my program that will allow basic revision control of text files. I was wondering what is the best way to impliment this should i use a library? or should i just execute the commands myself?
Ive tried to use the .Net cvs library from the same people as sharp develop (http://www.icsharpcode.net/OpenSource/SharpCvsLib/default.asp) but i cant find any documentation for any of it... has anyone sucessfully used this library and if so could you give me some pointers.
Thanks

I think System.DirectoryServices would help you here, not sure if it would allow to retrieve password.
For exchange server you can use CDO through COM Interop

Hi,
What's the "by the book" way under .NET to store application settings? (i.e. things you'd write to the registry under win32). I figure it's probably some XML file located with the app, but I need different data for different users, etc.

Add a reference to the System.Drawing.dll assembly.
The using statement (as it applies to namespaces and classes) just makes it so you don't have to type as much, it doesn't do anything to the actual code that is output. To actually use a new assembly you need to add a reference to it (in VS.NET right click on your project and choose Add Reference...on the commandline use the /ref:<assemblyname.dll> compiler switch).

Question: I'm trying to update a progress bar with the load progress of a webpage. On my form I have a webbrowser control and a progress control. I'm trying to use the ProgressChange event but it fires for every item that has to be downloaded (images, etc). So when the page loads after the first item completes the progress bar is finished even though most of the page is still loading. My question is how do I know what the progress is for the entire page instead of simply an item?
Many thanks in advance.

Not a C# topic, even if your source code is C# based. Probably the web development forum will be listening.

Why does the following line of designer generated code fail ??
this.imgTabImages.ImageStream = ((System.Windows.Forms.ImageListStreamer)(resources.GetObject("imgTabImages.ImageStream")));
Error:
An unhandled exception of type 'System.Reflection.TargetInvocationException' occurred in mscorlib.dll
Additional information: Exception has been thrown by the target of an invocation.
Thanks

I think this can happen if the image stream that is compiled as a resource is of a newer version than the ImageList win32 control supports. This will typically happen when you have VS.NET using the XP theme styles (by placing a devenv.exe.manifest file in the same dir as devenv.exe) but don't enable XP themes for your application.
This is because version 6 of the common controls writes a different format than the previous versions. I assume it is different because of the support for newer bit-depths.

How would I convert a String variable to a byte[] array and back again?
I should say for completeness that the reason why is that I need to save large strings to a SQL server database and read them back again and SQL server "image" field type seems to be the best choice for this since I don't know the lengths that might come in. (they are emails in mime format)
