The properties Console.CapsLock and Console.NumberLock provide the necessary information.

this weeks tips:
- make Visual display line numbers: Tools/Options/TextEditor/...
- show exceptions with ToString() to see all information
- before you ask a question here, search CodeProject, then Google

Thanks so much. Its working.
But stil a prob.
This is when the application start it detects if the CAPSLOCK is ON then I can display certain msg or so...

But I want whenever CAPSLOCK button is pressed then it should update the status of the panel in the status bar.

If CAPSLOCK is ON then status bar panel should show ON.
If CAPSLOCK is toggled i.e. OFF then status bar panel should show OFF.

Something like this...

Thanks in Advance...;) Smile | :)

Hi,

there are at least two ways to keep your status bar up-to-date:

1. on your form, set KeyPreview true; then add an event handler for KeyDown;
the handler now will fire for every key moving down; in the handler check for Keys.CapsLock;
if it is, use Keyboard.CapsLock and update the status bar; don't try to count the toggles
yourself !

2. on your form, add a Windows.Forms.Timer and let it fire say every second;
in its Tick handler read Keyboard.CapsLock and update status bar.

The choice is yours, it depends a bit on which of those handlers you may already have
for some other reason.

You're welcome.

Come to think of it, I would prefer the timer approach; with key events, if your app
looses focus, capslock gets toggles, app gets focus back, you will not know about the
change (unless you add code to some other events too, such as Activate).

Hello

Im writing a Word application that shall be used on machines with Office 2003 or later versions. On the developer machine I have Office 2007.

Im having trouble creating the application so that it works on the test PC witch is using Office 2003. Can anybody help me with a solution on how to use a assembly from Office 2003 in my project... C# Smile | :)

Hi
.Net framework itself provided you with Word library (In reference COM Tab you can see Microsoft Word Object Library) this should help out you to work around Word applications.

Thanks

Thanks for the reply

The Word Library only contain version 12, witch is Office 2007. If I compile my application with that library and deploy it on a machine with Office 2003 I get this error:

System.IO.FileLoadException: Could not load file or assembly 'Microsoft.Office.Interop.Word, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

So I need a way to compile my application with Microsoft.Office.Interop.Word, Version=11.0.0.0

Thanx

OK., when you add the reference into your project you will see some DLLs like

WORD
VBIDE
MICROSOFT.Office.Core

While you create setup you need add that library as part your setup and there you will see one DLL called MSO.DDL go to the properties and in Register Property select "vsdrfCOM" and build your setup.

This you no need to have any MS Office at your deployment PC. Please let me know if you havve any hiccup.

CreateHandle() error on an Overriden Tooltip for the DataGridView [modified]

7-Aug-07 22:23

Hello,

This will be a pretty long message so please bear with me, and thank you in advance for your help.

For the DataGridView, we needed to disable the ToolTip of the cells for all the columns EXCEPT for one column. And we wanted the ToolTip for that specific column to always show (and not hide after a certain amount of time).

My understanding is that the ToolTip of the DataGridView cannot be exposed, and therefore we had to do a work around. What we did was to create a class that extends the ToolTip and also a class that extends the DataGridView. The new tooltip class, named ManualToolTip, is then instantiated in our extended DataGridView class. (Note: there are other reasons for extending the DataGridView, but extending the ToolTip was done solely for this purpose.) Now, doing this created a lot of problems, I will not copy paste some code snippets and the error that we are getting.

My guess is that I am not understanding the ToolTip correctly. It could be that it is creating and disposing differently than I thought. Could it be that a separate ToolTip instance is created per cell in the table? And does it Dispose when you do a Hide? Well, I'm really just guessing. I need help! Or, at the very least, direction.

Thanks in advance!

what do you mean insert the numbers?

you are writing base on Console or Windows ?

here is just a hint because I don't know what you are doing!!!

for Console

use Convert.ToInt32(Console.ReadLine());

and I suggest you to get a C# book!
