this the line:
if ((string)search_form.Tag == "BROWSE_PATIENTS")

foreach (Form search_resul_form in this.MdiChildren)
{
frmSearchResult search_form = search_resul_form as frmSearchResult;
if ((string)search_form.Tag == "BROWSE_PATIENTS")
{
You will have to put in a break point and examine all the objects that may be null. Bear in mind that the error could have occurred before line 1718.
1) search_resul_form as frmSearchResult, will be null if search_resul_form is not a frmSearchResult or a derived type.
2) ((string)search_form.Tag == "BROWSE_PATIENTS" could fail for two reasons. Either search_form or Tag is null.

I have noticed the following:
if I start the application and then invoke the searcH_form then invoke any other form then call the search_form it will be activated normally without a problem
but If I start the application then call anyother form and then try to call the search_form then thsi error will occur.

Possibly something is not being initialised properly. Bear that in mind, but concentrate on determining what is causing the null reference exception as that will direct your search towards the mistake in your code. Use the debugger to find the null object and go and do it now!

From the line number there are only two possibilities
frmSearchResult search_form = search_resul_form as frmSearchResult;
Either frmSearchResult is null or it is not a search_resul_form;
Either case will result in search_form being null. And that is the only possible cause of your error.

OK, so write it! What? You didn't really think WE were going to do it for you, did you?
Or did you mean to ask a question? I don't see one in your post.
|
|
|
|
|
Is Google not working for you?
Or do you perhaps not know how to use it?
Hint: read a gmail mail using c#[^]
In future, please do at least basic research instead of wasting your time and ours.
If you get an email telling you that you can catch Swine Flu from tinned pork then just delete it. It's Spam.

can i make ant hacking software in C#

How the hell should we know?? We don't know anything about your skill set at all.
So, the default answer, since you're even asking the question, is no.

This is not a hacker site and I don't think anyone here will help you with this question.

No.
Ants are insects and are remarkably difficult to hack: they are very small, so hitting them with an axe is difficult, and they do not have internet access so virus code injection is next to impossible.

The perfect and complete solution is this!!!

it is not good to start learning with hacking......there is so many technologies that is best from hacking to learn.....and safe for career also...

Just to tell it to you: This is not Google and our services can only be used without sarcasm and dumb answers if you have searched Google before.

The fact that you ask the question

gives you the answer ! No you can't, otherwise you wouldn't ask.

i have a probleme with Fingerprint Identification iam using sourceafis to identify but i cant the Afis.Identify function
|
|
|
|
|
You can't WHAT?? Your post made no sense at all.
If you've got problems with a specific library, then your best source of information is the manufacturer of that library.
|
|
|
|
|
i cant get the afis.identify to work
and this is a free library
|
|
|
|
|
Well, then go back to the site where you got the library and see if there is a support link somewhere or maybe a forum dedicate to using that library, whatever it is.
I don't have enough information to even tell you who made it!
My bad. It's a SourceForge project. There's a Support link on it's page. Click that and follow the instructions to contact the people who made that library.

thanks
but the problem is i need to extract the template from the fingerprint each time i need to identify someone
and that takes 45 second depend on the database for me this to slow
my problem is with passing the database values
for exemple
List<datarow> dtrows = dt.asEnumerable;
and then convert each datarows to bitmaps
and then convert pass the list of bitmaps to a list of fingerprints
and then pass the fingerprints to the persons
for exemple
person.fingerprints = fingerprints;
and then extract each fingerprint passed to the person with the Afis.extract(person) function
and then instead of using afis.identify function i use afis.verify which is toooo slow and i cant get afis.identify to work
|
|
|
|
|
AGAIN, your BEST source of information is to ask the people who wrote the library. NOT a bunch of people who have never used it, let alone heard of it.
