Windows uses internally UTF-16 for strings. When having UTF-8 encoded strings, they must be converted to the encoding used by Windows.
With C# this requires having the UTF-8 string in a byte[] array. Then use the encoding class to convert the byte array to a string. See Encoding.GetString Method (Byte[]) (System.Text)[^] for example code.
BTW: What is a "mats" file? A MATLAB file?
If so read the UTF-8 string into a byte array and perform the conversion as described above.

Seriously? You dump 743 lines of Pascal in a question, and expect someone here to convert it for you? 
Either find a tool to do the conversion, or convert it yourself.
If you get stuck with A SPECIFIC PART of the conversion, someone here will probably be able to help. But nobody is going to convert the whole program for you!
"These people looked deep within my soul and assigned me a number based on the order in which I joined."

Don't.
It may seem to fit the bill for you homework question, but blindly converting code from one language to another does not normally produce code that is any good in the destination language. Pascal is not C#, and does not use the same underlying framework. If you must, understand how it's doing whatever it is doing, and adapt the algorithms to C# in a new application. But don't try and get it translated and assume you will get a good grade: you won't. And that's ignoring that your tutor is aware this site exists and will almost certainly spot the plagiarism...
Besides: that code is very, very poor - it looks like it was written by three chimpanzees who never actually spoke to each other ...

Chimpanzees write better code than that...  Maybe it was actually written by a cat walking across the keyboard?

I draw a radar screen with C#. In radar screen, planes(PictureBox) can move from start point to end Point. Scanning Line can also run. Although, I cannot code tracking line behind the planes for my poor knowledge. May you help me?

This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind.
So show us what you do to make the planes move, and what you have tried to draw the "scanning lines" - we can't really help from little or no information!

You're going about this all wrong.
Specifically, you're liberal use of PictureBoxes. The PB control is just a quick'n'dirty control to show an image. It is not designed to handle layering and animation and is just going to complicate things for you, immensly.
What you should do is get rid of all the PictureBox controls and handle all the drawing yourself on the surface of a control, like a Panel. You get the greatest amount of control this way. This is kind of what you're doing in the Paint event of whatever control that is.
Also, SetStyle calls should never show up in a Paint handler or any other drawing code. That's a one-time use call that should show up only in the constructor of a custom control or form.

To elaborate on Dave Kreskowiak's post.
- You need a panel (you can change the background color if you like)
- Learn GDI+ if working with winforms. Basically it involves putting the handle of the panel into a Graphics object and from there you get access to drawing tools like lines, ellipses, rectangles, ...
- If you do have the Graphics object you need code in place to redraw everything, else all the updates will draw over the previous situation.
This should get you started.

hello pple, my name is patrick, a university student persuing a bsc in computer science. am thinking of coming up with a software that uses fingerprint to carry pout transactions, i need help on how to do it kindly

Hello Patrick. That was nice an polite of you (I'm Pete by the way).
As you may have gathered from the response from OriginalGriff, you need to supply a lot more detail when you are asking a question. When you repost your question, make sure to tell us what code you have, what isn't working and what you have tried. That way, we will know what to focus our attention on.

How to do what, exactly? What part of this are you having a problem with?
So far, you have provided a vague title for a project, but have not defined, in precise terms, what this app is supposed to do, and the scope of the application. That's your first step.
Transactions? What transactions? Database transactions? Monetary transactions? Transactions between what and what? Or Who and what? Or Who and Who?
How are these parties going to enroll in your system? What authentication methods are going to be used, if any depending on scope? How are you acquiring credentials to identify the parties involved? Do you need a fingerprint verification on both sides of the transaction?
... The list goes on. If you don't define the problem you're trying to solve, you not going to solve the problem at all.

I tend to reject outright anyone that communicates at a kindergarten-level ... maybe you want to consider working on that before you "graduate".

Your question is so vague, it can cover about anything even remotely related to fingerprint.
Please refine the question.

Hi Team,
How can i call function from Forms through any of the controls?
Suppose i have function Validate() in FrmTest.cs under Global\Forms\
FrmTest.cs
private void Validate()
{
}
And control TestControl.cs under Global\Control\
TestControl.cs
For any drop down event changed,i need to invoke the function Validate() from FrmTest.cs.
Any suggestions will be great helpful
Thanks in advance
Manju

You need a reference to the class that contains the Validate method. But without some more details of your application it is difficult to be more specific.
|
|
|
|
|
You're doing this backwards. The control shouldn't know anything about the form it's on. It might not even be in the Controls collection of a Form. It may be a few levels deep in other control containers.
The control should validate it's own content, not the form.
