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

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.
|
|
|
|
|
Add a (public) "delegate" or Func<t1,...> instance to your target control that is automatically called by the event in question; the "default" response / behaviour of the delegate can be whatever you want (like a NotImplementedException).
Otherwise, you pass in a reference to "Validate()" and initialize the delegate with that reference when the target control(s) are created.
That's a generic way for attaching extra / new behavior to an object.
Depending on the development context (Windows Forms; WPF; MVVM; blah, blah), you would probably adopt some other technique (like "command binding"!).

how could i develop a wcf with multiple binding. say i would like to have one http binding and one tcp binding and now i want external user will use http binding and internal user will use tcp binding but if external use know tcp binding address then they will not be able to use it. this is the area i do not know how to handle. anyone give me some hint how to prevent external user to use my tcp binding ? thanks

|
Allow the binding to be set up through config and don't allow access to the tcp binding through any external facing firewalls?
|
|
|
|
|
can we prevent tcp access by code? can we detect request is not coming from a specific domain ?
please guide. thanks

Have you had a look at the authorisation options here? You could authorised some users to access via one protocol and others through another.

say suppose i have few files in folder and when any file content will be changed then i need to get change file name. how could i do it with hashing technique. i do not want to use file system watcher or directory watcher.
just by hashing technique how could i do it. thanks
tbhattacharjee

You would need to read each file at regular intervals, calculate its hash value and compare with the original. Not a difficult issue, but also not very efficient. A filesystem watcher is a much better choice.

You cannot prevent a message being treated as spam, except to not send "spam like" messages: it's the content that triggers the detectors as well as the source address.
If you send me spam that gets through, I tell the spam filter "it's spam" and it learns to treat you as junk mail in future.
You cannot prevent that. For registration completion emails, you need to remind us that if they not recieve it they should check the "junk mail" folder and add your address to the email Whitelist.

No.
Because as you have been told before, we do not condone, support, or assist in the production of malicious code in any way, form, or manner. This is a professional site for professional developers.
If you want to know how to do such things, you need to visit a hacking site: but be sure to disable all firewalls and antivirus products first or they won't trust you enough to tell you.

How to make program that from given numbers calculate give value or if he can't calculate that value he should find closest to that value?
Design of program: [^]
In first three labels is random generated three-digit number,in second four labels are random generated numbers can be from 1 to 9,in third label random generated numbers can be(10,15 or 20) in fourth label random generated numbers can be (25,50,75 or 100).
When user enter expression computer must calculate it and tell him what he calculated.User also cannot enter numbers that were not random generated inside labels.
After that computer must calculate expression and show steps how did he made it or if he can't calculate give random number from first three labels it should calculate closest to that value and show steps how did he calculated it.
When all these number are generated user have 60 seconds to make expression from give numbers,if time expires user enter expression if didn't enter it earlier and if he does have or doesn't have same number as in first three labels then he got points based on:
1.If he has same number as in first three labels he gets 30 points
2.If number is different for one he gets 20 points
3.If number is different for five he gets 10 points
4.If number is different for ten he gets 5 points
5.If difference if less than the number offered he gets additional 5 points
