Have you associated the image list with the tool bar using the ImageList property?
Can the program access the images at runtime? (Either from a resource or from file)

DBGrid problem???

Hi,

I create a customized DataGridTextBoxColumn class, I override the Paint method. everything is fine.

My question is how to get rid of the textbox control's focus, that means when user click on a cell, the textbox will not show (like no I bar).

I try HideEditBox() on the gotfoucus event of the textbox, it works, but with a blink. I try the textbox.caputured property, it doesn't work.

is there any good way to solve the problem??

Thanks a lot!

Hi,

override Edit in your customized DataGridTextBoxColumn class and don't call the base implementation.

I want to make a tool that just like "Windows Picture and Fax Viewer overview".

1. Increase or decrease the image preview size.

2. View the image in full size or as the best fit for your window.

3. Manage image files and print, save, delete, or change file details.

4. Open the image in an editing program if you wish. Note that this closes Windows Picture and Fax Viewer.

5. Rotate images right or left by 90 degrees.

Thanks a lot for help in advance!

This is all possible using GDI and C#:

1, 2 and 5 can be done using Graphics and the System.Drawing namespace
3 using System.IO
4 using the System.Diagnostics.Process class

Search CP for GDI and System.Drawing articles

Hello, Once I make a .NET software and I can put that message "Copyright owned by me..etc" in the HELP - ABOUT... but is it enough ? If some one decompile my code and make another version with his copyright name, what is the protection here... Should I have to register my product with some copyright protection companies etc... ?

Copyright can be thorny at times. Any original work which you create in most countries automatically gain copyright protection. This is the situation in the UK, where there is no need to contact authorities or pay fees to have something copyrighted (In fact there is no such procedure).

If someone was to decompile your executable and completely reimplement the algorithm then this is legally fine. Notice I mentioned "completely"; this would involve rewriting the decompiled code to avoid the similarities in syntax whilst performing the same algorithm. Now if they were to pass your original code (however they gain it) off as their own or using the decompiled code without reimplemtation this will break that copyright protection.

Copyright doesn't protect the idea or algorithm, only the implementation of that idea/algorithm. If you want to protect an idea/algorithm then patents are the only legal means. E.g. Amazon patented the one-click shopping cart. Personally though, I think patents are nasty, and hinder software development.

I'm no lawyer, so what I've said may not be totally accurate.

Regards, Graham.

Thanks Graham for your reply. I understood and i got my answer. I found dotNetProtector as a nice software for obsfucating .net assemblies but it is expensive (300 euro = almost 500$ Canadian), So I was thinking, what is the risk if I dont obsfucate my code and directly publish in CNET and my website for sale, but now I realized I should go for dotnetprotector to obsfucate, atleast making decmolie process harder unless someone is really desparate to break my codes...

Thanks again

Obsfuscating your code I think is the best solution. BTW, Visual Studio comes with a free community edition of a obsfuscator. I'm sure there's a link to the installer from the Start Menu.

I did not understand, Which Start Menu , did u mean Start page of Visual Studio Editor ? If so, then I did not see any link to that free obsfucator in that start page. If you know the link, would you please give me that.

Thanks again.

Ive only ever heard of one type of Start menu... its in the lower left of your screen by default and has links to your program files in it.

The Start Menu?! The one in the bottom left hand corner of Windows!

Start Menu -> All Programs -> Microsoft Visual Studio .NET 2003 -> Visual Studio .NET Tools -> Dotfuscator Community Edition
