The HotButton control is an alternative to the standard Windows button for C++ or Command Button that ships with Visual Basic, anc can also be used on webpages by using the text properties provided (for things like fonts and image paths).  

Setting Properties Programmatically

Most properties can be set programmatically directly at runtime.  For example,

HotButton1.BackColor = &HFF0000

The Font properties are the exception.  To set the font properties at runtime, you must do it by getting a reference to the Font object, setting the properties on it, then setting the Font object back into the HotButton.  Here is an example:

Dim font As IFontDisp

Set font = HotButton1.font
font.Bold = True
Set HotButton1.font = font
 

Using Graphics from EzStor files

One of the coolest things you can do with the HotButton is use graphics stored in EzStor files that you ship with your Windows  applications.  This feature is essential when using HotButtons on webpages.  For example, suppose you are embedding WOW controls in your Windows app, and you want to take advantage of the cool features of the HotButton on the webpage.  The form of the path for the HotButton is:

<external path>::<internal path>

Example

c:/Program Files/MyApp/Sample.hsp::graphics/logo.gif

Using our HSP product, you can generate the HTML for the page dynamically, including the path to the EzStor file.  You would use the Server.MapExternalPath method to obtain a path to the EzStor/HSP file, then use this path in the PARAM tag.  Here is an example:

<%
Dim strExtPath

strExtPath = Server.MapExternalPath("Sample.hsp::graphics/")
%>

<OBJECT classid="clsid:D7E03B4F-415B-4cc0-A6E1-43D3886CA698" id="btnBack" width="56" height="14">
<PARAM NAME='_cx' VALUE='1750' />
<PARAM NAME='_cy' VALUE='850' />
<PARAM NAME='ImagePath' VALUE='<%=strExtPath + "prev.bmp"%>' />
<PARAM NAME='HotImagePath' VALUE='<%=strExtPath + "prev_hot.bmp"%>' />
</object>
 

Using Graphics from Resources compiled into your .EXE files

Another cool thing you can do with the HotButton is use graphics compiled into your .EXE as Windows resources. To do this, you must create custom ICO resources in you .rc file, something like this:

IDI_DELETE ICO DISCARDABLE "res\\delete.ico"

Then, set the "ImageResID" and "ImageResType" properties of the HotButton to reference this resource.  If the value of IDI_DELETE is 202, then set ImageResID=202, and set ImageResType = eICO.

If your module is a DLL, you also need to set the "ModuleName" property as well.  This is so that the HotButton can find the resource in your module that has been dynamically linked into the running .EXE.  For example, if your DLL name is "mydll.dll", then this is what you set into the ModuleName property.

Setting Menu Properties as Text

The HotButton's menu definition is stored as text in the "MenuItems" property.  When you use the Menu Builder Property Page of the HotButton, it stores the menu definition as text.  This allows you to create a menu definition using the Property Page (in VB for example), then copy it as text to use to create a menu programmatically (in a webpage for example).  Here is an example:

<OBJECT classid="clsid:D7E03B4F-415B-4cc0-A6E1-43D3886CA698" id="btnMenu" width="56" height="14">
<PARAM NAME='_cx' VALUE='1750' />
<PARAM NAME='_cy' VALUE='850' />
<PARAM NAME='MenuStyle' VALUE='2' />
<PARAM NAME='MenuItems' VALUE='text:&1 Technical; id:1; |text:&2 Ivy; id:2; |text:&3 Chess; id:3; |text:; id:0; style:+sep; |text:&Select Stationery...; id:4; |text:; id:0; style:+sep; |text:&No Stationery; id:5; |text:&Web Page; id:6; style:+gra+dis;' />
</object>

As you can see, these unique features of the HotButton allow give you the capability to use HotButtons on webpages.  This is especially useful when you are embedding the WOW control in your Windows applications, since the HotButton gives you a lot of extra functionality and is easy to use.
