no problem it will generate when you start the app from IDE 
My small attempt...

As you see, whenever installing an new software, you must have a license number to register your application.
Now, i have assigned to do that license part in my task but i don't know how to generate a license num or how to make a license checker professionally (in C#). So, anybody can help me this?

Well, no-one is going to tell you how they make THEIR license keys, b/c that would let you generate your own. There's all sorts of ways to do it, the simplest is probably a variation on hashing the username, perhaps salting it first.

I think that article's a good start. Though I don't think you'll be using C++. You can choose between C# and VB.Net, whatever you're comfortable with.

Not really relevevant to the specific question, but:
1.) You have a "Shift" key - Don't be afraid of it (Seeing as the only capitals are C#, VB, C++, KB, MSN)
2.) Encrypt your given e-mail address. People can Phish it. Change to something like 5narmon5@gmail.com - And ask people to remove the 5's. (If they DESPERATELY want to e-mail you, they can use your Profile )

Is there something in WPF which would be an equivalent of CustomLineCap in GDI+? How do I implement a custom line ending in WPF? Thanks!

Not much WPF traffic here, but what there is, is mostly in the WPF forum.

Hi,
I have a windows form application. How do you detect if a form is shown within your process. I have no control of other forms that are shown in my application cause some of them are inside a dll.
MyMainForm (exe)
|--> ModuleDLL (dll)
|--> Forms (I have no way to know when they will be shown)
Thanks,
BJ

If you have the source code to the DLL, you could post an event to your main form from the child forms' "Shown" event. However, I can't for the life of me come up with a valid reason that the parent form would want to know when a child form was shown.
However, without knowing the nature of the app *and* the DLL, it would be impossible to comment with any authority.

Thanks for the reply. I have no source code for the DLL. I wanted to know if a form is being shown because I wanted to replace or modify the controls on the form that is being shown (i.e. set a background, change colors of a button).

The forms are created inside the dll ? Then how can you add stuff to them ? If you have a reference to the form, to interact with it, then you can subscribe to it's events and check it's properties

Yes I have a reference to the form using Application.OpenForms. But I just thought that there would be an event that I can attach to if a form is currently being shown. Hmm, I think I should see if there's such an event in the Application.OpenForms collection.
|

OK, then, there is a Visible property on the form, if you want to know if it's currently visible. An event fires when it becomes visible, not when you grab a reference and want to know if it was shown before you got it.

Hi,
I think Application.OpenForms is your friend.

Thanks, I'm actually using that. You gave me an idea, I'm gonna check if there's such an event in the OpenForms collection to see if a form is being shown.

Hi,
I'm encountering problem while trying to load unverifiable assembly (mixed managed and unmanaged code written in c++.net) using Assembly.Load(byte[] buffer). An "Unverifiable code failed policy check" exception is awlays thrown. The same error did not appear when I tried loading using Assembly.LoadFile. Unfortunately, I can only use Assembly.Load because I'm only given the assembly image in an array of bytes and I'm not allowed to write to any other storage devices due to security reason. Did I miss out anything? or Does anyone know any alternatives to load assembly other than Assembly.Load?
Regards,
chew

Very odd. On this Windows Server 2003 R2 box that my client has, the call to "ShowDialog" in the OpenFileDialog and SaveFileDialog classes are crashing. No useful information is provided other than "External Exception".
Anyone encounter this?

You could try going through VS Debugger (if it is available on that machine). Otherwise I would check for Explorer plugins that are interfering with those two dialogs. Is this problem with all open/save dialogs in the OS? Do you have proper privileges to show those dialogs?

Yup. Tried that. Crashes in "external code", as in the Win32 API.

Well, this machine has a bunch of SharePoint stuff loaded on it. Does that count?

Given that it happens sporadically, not sure. Also, given that the only way to access this computer is with remote desktop (terminal services), that adds another twist to the problem.

Yes.

Do you have enough permission to show them?

I've never seen this before, but I think you might want to try reducing the complexity from your code, and start with just a plain openfiledialog. Then I would add back the custom settings I assume you're using until you find the one that's breaking the dialog box. To be extra safe, I'd probably do it in a test app instead of the program you're working on.
If it were a permissions problem, I would think you're get something more specific than "external exception". It sounds to me like R2 has something in it that .Net doesn't like. BTW, what version of .Net are we talking about, and does your client have the latest version of it installed?

I'm considering that, but in all honesty, this:
OpenFileDialog ofd = new OpenFileDialog();
ofd.RestoreDirectory = true;
ofd.CheckFileExists = true;
ofd.Filter = "rpt files (*.rpt)|*.rpt|All files (*.*)|*.*";
ofd.Title = "Load Report";
DialogResult res = ofd.ShowDialog();
is quite simple already. Sure, I could remove the RestoreDirectory and CheckFileExists options.

If the code that you just posted is what you are using why would their be any errors regarding Win32 API? Is the bug before or after the segment you just posted but only shows symptoms during the ShowDialog method?
