Correct, for example the API that Microsoft provides with Vista / Windows 7 that I suggested does this, it is available for you to use in your code.

~~Perhaps he~~He almost definately used an API.

Now I realise this is a hard concept to grasp, buy as a developer, I assume you'll understand the following:

Possible != Easy.

Practical voice commanding certainly falls under the "fantastically hard" category, which is why people use the 3rd party APIs (like the Microsoft one I suggested). It is also why none of the APIs work perfectly.

Basudevkuet wrote:
if you know please give idea about the process

The process is as follows:

Look at the wikipedia entry on my original post
Google for SAPI 5.3
Research and use SAPI to provide the functrionality you want
If you then have specific problems, come back here and post a question following the guidelines

If you make a decent stab at steps 1-3, you are unlikely to get flamed here at step 4.

Validation Ent Lib issue

hi ppl ,

I am using Ent Lib for validation in my windows forms application. I have a set of comboboxes which are bound to a datasource. When the selectd value is null the validations happens on it. but when I select a item from the dropdown , I am getting a validation error as "The supplid value could not be converted to the target property type".

I have defined a "Not Null Validator" for the combobox selected value in the enterprise library validation.

Help would be appreciated.

Thanks

Capture and replace mouse cursor on the fly

Hi All,

A bit of background on what and why I am trying to do this. I have a 3rd party c# component embedded in my form. The component controls the cursor when the mouse is over it. I can set different cursors for the component when I initialise it but they must be mono-chrome as this is all it can handle. The component also does not process right-click menu clicks, but I have managed to circumvent this using a mouse and keyboard hook to process these actions.
Ideally what I would like to do is something similar with the mouse cursor - ie trap when the component is changing it's cursor according to the action being performed then selectively repaint the cursors with my own versions. I really need to be able to listen for some sort of event being raised I think.

Does anyone know if this is even possible? Any code or links?

Many Thanks.

There is no notification that the mouse cursor was changed by an outside process. Since it can change just moving from control to control or window to window, this would get very tedious to handle.

I don't know of any way you're going to be able to handle this.

Convert font to string and then back again...

Hello,

i have an application where my user changes font and font color for different labels etc and they save it to a file but i need to be able to convert the font of the specified label to a string to be written to file, and then when they open that file my program will convert that string back into a font object. How can this be done? I haven't found anywhere that shows how it can be done.

thank you

bael

You have to do this yourself by creating a data structure or string that contains all the font characteristics. You then write that alongside your text, and when you read the file back, reinterpret the font details to display the text in the way you want.

'Matrix' cound not be found.. .

When I try to use "Matrix" or "RotateTransform" Visual Studio complains that "type or namespace" could not be found. Do I need to install the DirectX SDK for these namespaces? MSDN reveals nothing helpful, and I cannot find anyone else having this problem.

I am simply trying to rotate a GDI object. Any help would be great, this has stumped me.. .

here are the namespaces I am using;

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

You need to use following namespaces

System.Drawing.Drawing2D
System.Windows.Media.RotateTransform

The MSDN documentation always lists the namespace you need, see here[^].

When you type a "known" type into VS, Intellisense helps you by putting a red line under the final character. Hover the mouse over this, and the options for binding appear, listing the namespace required: add the using, or explicit reference. (You can get the red line back by placing the text entry caret anywhere in the type name.)
