I have this home project... at home.
It has lots of project.
I am also using Nuget to get some 3rd party library.
One of this Nuget package in particular contains 6 DLLs.
It is used in 4 projects... (a bit messy to update)
Now one of this DLLs has a nasty bug. Fortunately the source is on Github!
Is there an easy way for me to debug this single DLL with my project? Without having to mess up with my Nuget packages?

If you can download the source from Github you can reference the project directly - it may all fall apart if the other 5 DLLs are referencing (never had to attempt that) it internaly.
Never underestimate the power of human stupidity -

Oh.. it turns out I can remove the DLL reference without removing the Nuget package!
After that I can reference the project and Bob is your uncle! 
Well.. just gonna continue testing my app until I meet this error again, sweet, thanks!

so basically I want my 3rd party program (which will be created using c# on WPF) be an interface between the user and that site. Using WebBrowser class I wanna load the login page and after the user logged in(and passed CAPTCHA), he/she will fill some fields in the program, and the program will use those data to fill the website fields.
after the user logged in to that website how can my program use his/her cookies to be able to access his/her profile to fill its fields?

It's quite possible that you can't - the info doesn't have to be stored in cookies, it can be stored in the Session which is entirely server based.
And even if you can, I'm not sure it's something we should be involved in: sites add CAPTCHA to prevent apps from accessing an entire site and / or submitting data automatically, and what you are asking is effectively bypassing that.
If you have a genuine need, then contact the site admins and ask them: they may give you a simple method (or tell you to go to hell).

Can anyone help me understand this. not too much luck finding anything in google?
using the following code to display a image in a button works fine
button1.Image = global::AppInfo.Properties.Resources.MyImage;
But if I trying to display the image on a windows Form listbox, it does not work
listBox3.Items.Add(global::AppInfo.Properties.Resources.MyImage);
This only displays "System.Drawing.Bitmap" text
many thanks in advanced

If you add it to a listbox as an item, it will try to find a string-representation of your object. The thing it is displaying means it is working, and correctly. If you want images TO the items, try the Listbox.ImageList. There's an example on MSDN.

You may get more helpful replies here if you describe what the bitmaps you want to display are ... are they icons; do they vary in size, etc. ?
Start here: [^] and figure out:
1. would using a ListView or DatagridView be a better choice
... if not ...
2. would the facility to use an 'ImageList with the ListView do what you want
... if not ...
3. are you willing to take on drawing the graphics yourself ... sub-classing the ListView and owner-drawing ... see: [^]

I have an event right:
private void dataGridView1_SelectionChanged (object sender, EventArgs e)
{
}
I would like to trigger an event when it is made:
private void dataGridView1_RowContextMenuStripNeeded (object sender, DataGridViewRowContextMenuStripNeededEventArgs e)
{
}
Simply that the RowContex event worked with SelectionChanged ...
I searched the Internet and these mean me on average: |
If you can, it can be an example of how to do it?

It's not a good idea, or even really necessary.
Instead of messing about trying to force events to occur, put the code in your event handler inside a separate method and call it from both locations. That way, you don't need to "force" events to happen (which is rarely a good idea) and you reduce the code in your event handler which is a good idea from a style POV.

it can not be otherwise. I created a dynamic DGV fill and it does not support the RowContextMenuStripNeeded event and the SelectionChanged event as much as possible. I also wanted calling the SelectionChanged event to involve calling the RowContextMenuStripNeeded event. So how to do it? except that it is not a good idea, etc.

Sure.

DoWork();
}

I tried it. But if I do as you write, this is the exception:
private void dataGridView1_RowContextMenuStripNeeded (object sender, DataGridViewRowContextMenuStripNeededEventArgs e)
{
e.ContextMenuStrip = contextMenuStrip1; <--- here: The object reference has not been set to the instance of the object
selectedrowindex = e.RowIndex;
}
Can you do something about it?
I also tried this:
private void dataGridView1_SelectionChanged (object sender, EventArgs e, DataGridViewRowContextMenuStripNeededEventArgs ee)
{
dataGridView1_RowContextMenuStripNeeded (sender, ee);
}
it can not be so ... because there is a mistake:
CS0123 error None of the overloads for the "dataGridView1_SelectionChanged" element match the "EventHandler" delegate.
Regarding the code from the deasinger:
this.dataGridView1.SelectionChanged + = new System.EventHandler (this.dataGridView1_SelectionChanged);
how to make it fit?

The e.ContextMenuStrip will be null if you call it by hand. It is set in code by the DGV that is calling the event. If you call it, you either must create your own DataGridViewRowContextMenuStripNeededEventArgs and fill it with the correct data, or find another way to determine which context-menu strip is meant.

That's not allowed, since both events have different signatures.

Could you show me how? Programming is not my strong side

private ContextMenuStrip contextMenuStrip1;
public Form1()
{
InitializeComponent();
dataGridView1.RowContextMenuStripNeeded += dataGridView1_RowContextMenuStripNeeded;
dataGridView1.SelectionChanged += dataGridView1_SelectionChanged;
contextMenuStrip1 = new ContextMenuStrip();
contextMenuStrip1.Items.Add("The turtle moves.");
}
void dataGridView1_SelectionChanged(object sender, EventArgs e)
{
DoMyBidding(null);
}
void dataGridView1_RowContextMenuStripNeeded(object sender, DataGridViewRowContextMenuStripNeededEventArgs e)
{
e.ContextMenuStrip = contextMenuStrip1;
int selectedrowindex = e.RowIndex;
DoMyBidding(e.ContextMenuStrip);
}
void DoMyBidding(ContextMenuStrip humbly)
{
}
This is what Griff was explaining in sorts, before you stated it cannot be otherwise

Please, anyone, help to make this?
Give me the source code of this project.

No. "Help to make project" is one thing, "source code of this project" is another altogether.
Two reasons:
1) We do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.
Try it yourself, or learn the Magic Words: "Do you want fries with that?"
If you meet a specific problem, then please ask about that and we will do our best to help. But we aren't going to do it all for you!
2) You do realise that your tutor is almost certainly well aware of this site - and others - and will detect very quickly that what you handed in was not your own work? Indeed, I know of several teachers who are regular visitors here ...
And there is a technical term for "handing something in when you didn't write it" - it's called "plagiarism".

Hi,
that is easy, just ask for a copy of your friend's home work[^] and adjust the wordings of the form titles and labels.

I am working on a desktop software that I eventually hope to sell next year.
It's an end user application, not a business app. It will cost like $30, or free if you don't mind the built-in nagware on every save.
I plan to have my licensing follow the following algorithm:
1. First Run
a. find a UniqueID for this installation
b. ask the server to provide a license key for that UniqueID (providing relevant info)
c. save licence key as text file in application folder
2. Later Runs
a. Find the installation UniqueID
b. Match system UniqueID to licence key
My problem now is step a., how to Find Installation UniqueID?
Idea 1.
One of the best candidate so far is to get a hard drive unique ID
Searching for a reliable hardware ID
Now, as some critics said, you have to license again if you change the hard drive.
However I am not sure how one could avoid licensing again on a new hardware / system.
Idea 2
Why bother with hard drive number, simply store a GUID generated on install, or first check and store in the Windows Registry.
Pretty much the same as idea 1 practically, as far as user experience is concerned though.
Other Ideas
Any better licensing model to suggest? or key generation method?
[EDIT]
Found something interesting in StackOverflow:
c# - What is a good unique PC identifier? - Stack Overflow
Which I can get with the following snippet:
static void Main(string[] args)
{
var key = RegistryKey.OpenBaseKey(
RegistryHive.LocalMachine,
Environment.Is64BitOperatingSystem
? RegistryView.Registry64
: RegistryView.Registry32);
using (var reg = key.OpenSubKey("SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion"))
{
var v = reg.GetValue("ProductId");
Console.WriteLine(v);
}
}

This is rather not a C# question. You are still deciding how to setup your license model. Decide that first and then implement.
I have some experience of this from my last employment where we sold licenses for an application. Several times I was asked from customers to handle crashed computers or new computers. We also had another application witch had a different license system, I prefer the later system instead of handling all by yourself. I will describe both systems.
The first system (handling all by yourself):
* We used a combination of the hard drive's ID and MAC-address to generate the ID.
* We told the customer to specify the ID and we then returned the license.
* When there was a crashed computer or the license needed a move to another computer. We sold them a "license move" with some discount. The customer had to specify both the old ID and the ID to get a new license. (This is a risk: Because the customer might be lying and actually the old computer still runs. Therefore you have sold one license for a cheaper price).
Don't store the license in the Window's registry! Store it somewhere else. Not there!
The second system (handling by a service-provider):
We used the service "Solo-server" from "softwarekey.com" which provided us with a database where we stored everything for the licenses. In our program we access the database to check the license for that customer. They supply with an online login to the database in any web browser and from there we created and handled all licenses for our customers.
When a customer bought the program we generated a new license with ID and password. After that we mailed the ID and password to the customer. The customer then "installs" the license on there computer. Our program connected to the provider's service and checked ID and password.
When a customer had a computer crash or needed to move the license. They uninstalled the license and installed it on the new computer. Same license (ID and password) but different computer. Of course we could deactivate a license for a customer anytime, and as soon as the program connected to the provider's system it deactivated the program.
I prefer this system many many times more then the first model. It was so much easier and better performance.
The only downside was when the customer didn't had internet access, which is required. But the provider had a solution for that by using another computer with internet access to create a file with the license. The "license-file" was then needed to be transferred to the computer by any means. That was the customer's problem  .
There is therefore a solution for offline handling. But if your customers can handle it online with internet access, it's a piece of cake.
