You can't create class variables dynamically, however...
Controls.Add(BUTTONx);
That puts the new button into the Controls collection so you can retrieve it when you want it.

So each Button a unique name value
BUTTONx.Name = String.Format("DynaButton{0}", counter);

Then look at how you can use the name to get the button from the Controls collection
Controls.Find(...);

You might need them to be referenced as relative paths, I've never had a problem before using images in the workshop. Just lay it out like a simple website (and always use relative paths where possible) and it should be quite happy.

I always hand-code the html documents (be it for a website or a help file) so maybe the best example I can give is this:

<html>
	<head>
		<title>Hello World</title>
	</head>
	<body>
		<img src="images/helloworld.png" />
	</body>
</html>

Hope that helps. I don't know how Word references the images.

I mean that the paths are relative in the html files. All that the project files for HHW do is define the structure of the TOC and Index and Search words. It then references all the files you want to add and simply compiles them. As far as I know it does not do anything more complex than that. An analogy would be it simply zips all the files with a TOC, Index and Search Keyword file which the HtmlHelp Viewer then unzips and parses the TOC, Index and Search files to produce the listings in the Help Window.

Documentation of DLL(.net) in design time

I built a library in .net using the xml tags for all the methods like this:
///

/// Apply non linear filters.
///

public void A(){} After I marked the option to generate XML Documentation File in the Project Properties. What do I must to do to include the xml documentation in my class library? My goal is to show all my method comments in a client class of another project. I know that exist some tools to generate the chm with all the documentation but I want to show it in design time, in others words, when I'm using the class library in the IDE as a client. Can you give me some hint?

Thanks you very much,

Marcel

I'm not 100% sure but I think you just need to make sure that the xml file produced is in the same directory as the dll being referenced by the IDE, i.e. VS will probably make a local copy if it's not in the GAC so the xml doc file needs to be in the bin\Release or bin\Debug directory (sorry you'll have to find out by trial & error or just put it in both).

Thanks you very much. I got it. You only must refering to the dll in design time and will appear the comments. After when you build the solution in the client project VS will generate the xml doc file in the bin\Release or bin\Debug directory. I was doing that but I don't refreshed the reference.

Now I want to change the icon to the dll and I know that I can do it setting in
HKEY_CLASSES_ROOT\dllfile\DefaultIcon but for all the dll. Is it possible for this one?

Thanks a lot,

Marcel

You should be able to just use the properties page in VS to set the icon of the dll. There is no point in using the registry. Just use the same method as you would for a WinForms application.

Sorry, I don't understood your explanation because I added in properties of project/resources/icon the the .ico and when I build the solution continue the default image in the dll. Can you explain in more detail?

thanks again,

Double Click Properties in Solution Explorer
Goto Application tab
In the Resources group box select "Icon".
Either:
Select the icon (if already in project)
Add the icon to the project by clicking the ... to the right of the combo box.

Formula 1 - Short for "F1 Racing" - named after the standard "help" key in Windows, it's a sport where participants desperately search through software help files trying to find actual documentation. It's tedious and somewhat cruel, most matches ending in a draw as no participant is able to find anything helpful. - Shog⁹

As far as I know DivX is a proprietary format so you must use their codecs, there might be some info on their website for interfacing with the dlls. Might be worth checking out their labs: http://labs.divx.com[^].

IMHO, this is an extremely complex program to write if you're just starting off.

I would think that the best place to start is some of the DivX forums. I don't know of any tutorial sites but will hunt around when I get some free time.

Forget what I said.

Use the System.Net.Sockets.NetworkStream class. There is 4 constructors, all taking a socket as parameter.

An interesting challenge. My initial thougth was sure, use the selectedText property, but damn it, it doesn't have that one Mad | :mad:

Only way I can think of is to handle the mouse events and calculate the position within the string based on the location of the event. Very complicated though.

do know how to trap the events in the datetime control when the up or down arrow is clicked. I mean when the up arrow is clicked i want to do something or when down is click, i want to do something different and want to do it before the value changes because the value change will depend on the what i do on those events.

Re: DateTime picker

Unfortunately there is no OnBeforeChanged event. Can't you handle the ValueChanged event and either revert to a previous value or allow the change?

OnValueChanged(...)
{
if( out of range )
dateTimePicker = OldValue;
else
do something
}

Hi there,

I'm coding a photo gallery desktop program and I'm planning to store the images in an MS Access DB (OLE field). The size of the images I got is around 600 MB... ~ 400 KB each.

What do think? Can MS Access handle it or I should look for an alternative?

Please advise. Your help would be greatly appreciated.
