hi all
i have a method that will represent an mdiChild form
it works ! but i want it to return a form with the type of entered argument (formType) what should i do?
/////////////////////////////////
private Form Find(Type form)
{
foreach (Form frm in this.MdiChildren)
if (frm.GetType() == form)
return frm;
return null;
}
/////////////////////////////////
i tried to use this one but it does not work!
/////////////////////////////////
private Form Find(Type form)
{
foreach (Form frm in this.MdiChildren)
if (frm.GetType() == form)
return (form)frm;
return null;
}
/////////////////////////////////
would u help me what should i write instead of "return (form)frm;" ?
thanks!

It's because of your return type.
You should just return the child form that you found, and cast it to the desired type in the calling method.
You may also have to fully qualify the type you're passing in (MyApp.MyAppChildForm instead of just MyAppChildForm).
MyApp.MyAppChildForm child = FindChildOfType(MyApp.MyAppChildForm);
if (child != null)
{
}
private Form FindChildOfType(Type formType)
{
foreach (Form child in this.MdiChildren)
{
if (child.GetType() == formType)
{
return child;
}
return null;
}
}
BTW, in the code snippet I posted, I changed the variable names in your Find method to something more appropriate.
EDIT - I changed the name of the method I posted to match the call the code was making... (slaps forehead)

thanks for your attention and variable`s name correction!
i do that conversion in my code ... but i what to make it better & more beautiful
i will try this kind of meaningful naming from now on !
but the problem still persists !

You could possibly make Find a generic method.

hi
would you give me a Little sample or show me a link about "Generics" that explain me this topic more simpler ?

Sure. Given a List<System.ValueType> (lis) containing values of different types, this will retrieve the first one that is of a specified type:
private static T
GetValue<T>
(
) where T : struct
{
T result = default(T) ;
foreach ( System.ValueType v in lis )
{
if ( v.GetType() == typeof(T) )
{
result = (T) v ;
break ;
}
}
return ( result ) ;
}
int i = GetValue<int>() ;
You can easily modify it to use Form rather than ValueType and make it more robust.

Dear my friends. I am currently a 3rd year computer science student and mostly we have learned programming languages and its the time to do our senior project. 2 of my friends and me are good programmers specially in C# and all of us have a good knowledge of Database design, System design,PHP ... almost we mastered all of the subjects.
But we need a better idea. If you have any idea that is either stand alone application, web application (either intranet or internet based) Please share me your ideas so we will have the best project in our batch.
Thank you

I'm sorry, but people here aren't going to give you ideas for your project. We have had many requests over the years and we never help with this one. There's a very important reason for this - it's your project, so it has to be something that you are comfortable with. Only you know what you are capable of as a coder, so only you will know whether or not you can tackle a particular subject. More importantly, the topic should be something that keeps you interested as you will be spending a lot of time on this.

Bullshit.
I'll help with ideas anytime. I'm not so good at providing code, but I never run short of ideas.

I agree. But you wouldn't want any of my ideas.
Instead, find your own. In today's CodeProject Daily News email, there's a link to an article about "10 Sharepoint Deployment Challenges". Fix one of them so that there are only 9. Or, if Sharepoint doesn't appeal to you, read another article with a list of 10 problems and fix one. Don't trust articles listing less than 10 problems because any worthwhile list has 10 items, and fewer is an indication that the easy ones have been fixed.

When you want to reply to somebody, there is the option to email them. I'd recommend using that option because you really don't want to put your email address in a public form - that's just inviting spam.

Ah, Senior Project.... I well remember it. I designed a submersible data collection system for a buoy 3" in diameter to collect sea water information and transmit it to another senior project that had to record the data. That was fun...
I have a project that I'm working on in my own time that you're welcome to take on as a senior project, and I think it would be a good match for your skills and interests.
I design and build electrical power substations, among a few other duties. In those substations there are 4 or 5 devices that we monitor for temperature, number of operations, current and voltage, that sort of thing. The number of variables is not large, but it's important information to gather so that we can predict when various devices will need maintenance before they fail. Each month I send linemen out to record on paper the values I need, then I enter them in a spreadsheet. That's not an ideal solution, and I'd really like to put the data into a database, then analyze trends to predict when I should take an item out of service for preventative maintenance. I'd prefer a solution using C#, since that's the language I'm now trying to master, and storing the data in a SQL Server database would be perfect.
The analysis part is beyond the scope of this effort- I'll add that myself. But the data collection part might be a good fit for your project. If this interests you, feel free to email me. If not, keep in mind that the major cause of project failures is the failure to limit the scope. Things that look easy in the requirements phase often turn out to be nightmares when it comes to actually implementing a solution.
For your project, keep it simple. The purpose of a Senior Project is to demonstrate your mastery of the subject matter, not to create an application to save the universe. It's awfully easy to lose sight of that fact. Good luck to you, and I hope you have as much fun with yours as I did mine!

Well, there's a first. This is the first time I've seen somebody offer sensible advice on a project idea in this forum. Whether or not this captures the OPs imagination is a different matter (or if they can sustain that for the duration of the project).

You're right about that! Sometimes what seemed like a good idea turns into a horror when the project gets into details.

Thank you for your help. Even if your ideas is good one, I think it will be difficult for me, because in our country your problem can be solved by electrical engineers not computer programmers. I think it needs working with hardware. But our main focus is programming and it is only software.
I found a new idea with my friends and it is something related to Mobile Banking System. There is no such thing in our country. If we do this, we will be the first one. Our main concern is the infrastructure will look like.
1) It is a mobile application
2) It needs a high security
3) There must be an intelligent system from the bank’s server side which will accept incoming requests and send the appropriate answer to each user.
If you have any idea about this please help me out. Thank you.

That sounds exciting, though I must caution you that it sounds too ambitious for a senior project. I do wish you well with the project, despite my concerns, and hope that you will consider posting your solution to CodeProject when it is complete. I think a lot of us would find it interesting and instructive.
And, by the way, I'm an electrical engineer, but a lousy programmer. The task I suggested is pure software, so it will take me a long time to make it work with my low level skills.
Good luck on your selected project, and I look forward to following your progress here in the forum!

Thank you for your help man!!!! But this times not only coding is a problem but having a nice documentation is a must! We are evaluated as follows
-65% Documentation
-20% Coding/Implementation
-15% Defense
So if we have a nice documentation I hope it will be easy to do the implementation. By the way if you or any body has an idea of Service Oriented Architecture (SOA) ... it would be nice to hear.
By the way if you have any contact would you please let me know so that I will contact you.
Thank you.

I'm glad to see that some schools still considwer documentation to be important. An awful lot of major software companies have lost sight of that fact. Well documented requirements lead to well documented functional descriptions which, if properly segmented and divided into small blocks, lead to easily coded chunks.
If this is a team effort, I strongly recommend an Interface Control Document which none of you may change without everyone agreeing to the change. In it you will describe in detail every public variable and type, every function, and whose responsibility it is to implement each. That way there are no surprises because A wrote an integer function which B called expecting a real result... That one document will save your ass. I use one even for my own tiny projects, simply because I have so little time to work on them that when I set the project down for 2 months because I got busy at work, when I get back to it I've forgotten what I was doing where. A review of my ICD tells me where I left off and what to do next.
As for contact info, click the email link below, instead of the reply link.

Find a popular application, and try to duplicate it.

Aaah, college. Back when I was there, one of the other teams was trying to write a competitor for Windows 3.0.
