I have an application that I am almost ready to package. What are options to protect your code from being copied by others and deployed to others ? Is there a way to keep your code from being copied ?

If it's VB.NET, there's not much you can do to stop people reading your code. Protecting how your app deploys for those who don't know how to read the code is another matter, lots of options there.

I'm having a strange problem with my forms in vb.net 2005
I created a new project by copying around forms from old projects.
Now, this new project runs OK (using the startup form of course), but it does not show the startup form as part of the project!
I can only seem to find the form by searching for a text string that I know is in it.
The code for the form is then visible, but the DESIGN of the form is not.
How can I open both the code and the corresponding design?

did you by chance put the form in a namespace? in 2005 when you put a form in a namespace, you need to put it in the code as well as the designer otherwise your form becomes a class only.

Hi.
I'm not sure exactly what you mean. Do you mean that I need to have this sub in my code?
Private Sub TopForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
If so, then do have it.
I think that my form exists (invisibly to me within the project) in the \my project folder. When I choose "save myproject topform.vb" the form is then also saved in the project's root directory. But then if I try to load the form from the root directory, it's as if the form is there twice and I get "duplicate" errors.
I can't seem to make the form that exists in the \my project folder visible to my project!
thanks again!

I am folder happy within my projects separating code and functionality. So I have a folder called 'forms'. I not only put all my forms in that folder but I also add a namespace to each form so that each form belongs to the namespace 'Forms'. ex: Dim oFrm as new Forms.Form1 In 2005, they separated the designer from the rest of the code with the introduction of "partial class"es. So if you put a form in a namespace you need to put the namespace above the class of your code as well as the partial class for your form so that each piece belongs the 'forms' namespace.
if you weren't using namespaces, then this obviously wasn't your problem. Have you tried to create a new form and copy the code in from the hidden on to see if that "corrects" the problem.

Same here, much easier to find your way around.

Interesting concept, not one that's occured to me before. Do you notice any performance benefits? Or is it just "a thing" you do?
I'd be interested in finding out more - would you write an article on the subject?

Peformance benefits...I would say no. But it's a good way to organize/categorizing every object/functionality within your project.
Article...well not sure. Some of these guys are bruttle of those that write articles. It would need to be well written and I'm not a gifted documenter... I'll consider it.

Yep, I've seen. Not shaking in my boots just yet tho, I've got two that I'd like to finish off and submit & to hell with them if they're brutal - it'll only teach (force?) me to write better code.

Can't be worse than some I've read here already. Give it a try, you've got nothing to lose and plenty to gain.

High all,
I have a small problem on a inherited combobox (VS 2005).
The code behind is to have the functionality of a "Readonly" box,
basically like the Text Box, and my readonly textboxes all have another
backcolor (out of our corporate identity stuff...). The combo itself works
just as expected, but with one little thing: it has a sort of ugly white
border around the editing area, seems it just colored the background of
that one...
If anybody had the same kind of problem, please let me know
Thanks

Hi
I am fiddling with Composite UI Application Block (CAB) from MS. I have created the application as directed, the modules are also loaded, however, I cannot see the user control loaded on my form.
The code in the InitModule does not get executed - why would be that?
Anybody played with this?

Hi All,
How can I Change Local Machine IP Address without rebooting the machine using VB.Net.
As I want to shift from one IP address to another IP address with application the effect should take place without rebooting the system.
Thanks in advance.

You'll have to use WMI and the Win32_NetworkAdapterConfiguration[^]to change the IP Address. Also, there is no guarantee that you won't have to reboot the machine.

You don't want a picturebox, I am often astounded at the things people expect those to do. You want to write your own control to do this. That is, no control will do what you want.

Drop a timer control on your form and change the color of your button in the timer event, based on whether the flag is set / updated.
Hope this helps

i have a database named Restaurants on MS Access and i have a table named Restaurants_avail where i have rest_name, Rest_loc, rest_tel and rest_type
I have already connected the db to my application and have been able to populate the combobox with the rest_name field. My question is this....when i scroll during runtime through the combobox, i want the textboxes to be filled with the location field and the telephone field....how am i going to do that??? I need some code pls
thank you very much for your time

Have you tried writing code in the Click or Change event of the combo box? You could query the database based on the combo box value and set the text boxes.
Hope this helps
