Normal classes, you just need a LOT of imagination on how you and the intended would hide the message without making it detectable by the rest of us. If you can do it by hand, work out what you'd do and put that logic into a program

Im surrpised it doesnt whine about drop throughs .. as there are no breaks in your switch statements. Ok, give us an example of the input values you have, and the output you expected, and what you actually got.

Or some code that you thought should work but doesnt.. (as long as you post errors, and or expected vs actual outcome)

when you debug it does PhotoID have the right integer in it? does the sql return any errors?

possibly the line feed isnt being sent correctly

Isnt that what they invented wap for?

No, you can have a large number of threads running at any time, although actual activity is limited and timeshared over the available CPU power of your box. eg, if you have a single CPU with HT - thus pretending to be 2 CPUs directly technically it does only 2 …

Well then, we'd need some code, we need the full error..

Having person recognition by camera, is not likely to be overly simple. working in conjunction with the door swipes so that on failure/success it takes a picture, sure.. so then a human can compare the entrys and decide if the cards been cloned, or stolen etc.

instead of getvalue - which returns a single value and as you specified no default option, if not found, it would return null.. Do you not mean getsubkeynames?

The problem would seem to be [code]return ((int)(result.ReturnValue));[/code] In old days thats probably a pointer to the result, but in .net youve told it to be an int, so an int it is. Try changing it to [code] return ((IEnumerable<Order>)(result.ReturnValue));[/code]

.bak files can be *ANYTHING*, however, if you just wish to rename them and or move them, then you are free to do so as a general rule.

running as a service?

You can take the hight and divide it by the row height to work out the number that would be visible, to work out which are on screen, hmm, you could probably use the scroll event to work out what the current position is.

Yep, thats exactly what Id expect it to do, employeeVariable is an array, the toString of which is as you saw telling you its an array of string.. Try checking the "join" function.

What code do you have?

Well, having read the assignment sticky you know we wont do it for you. If its deleting all employees then your coding is wrong, which I guess you know, but, we have no code to comment on. Have you covered databases on your course?

Problem is you havent told it what to do about the exception, you need to tell it to do something.. and you then need to tell it to continue.. Without that, its doing exactly what you've told it to do

That sounds odd. Normally if its a newer version the .net framework will pick up the fact the versions changed and the cached version is updated.

Attributes in c# terms are different, while you and I call a persons eyes an attributes, in computring terms they are properties.

Time_key is set to 100 so your criteria is never met.

if you look at: [code] until (call_start >= 0) or (call_start <24); repeat //repeat 2 writeln ('please input call length'); readln (call_length); until call_length > 0; [/code] You have an until without a repeat. Hence you get a confused bit.

Installed only once? You would need to make the installer only allow it to be in 1 location, wherever that user chooses it to be, and on running to check the registry for where that location should be, and if its not there, complain and exit.

Then I would suggest you use the debug and step through your code, as it implies its not reaching the stage where it would show the dialogs you're expecting. It would be easier to see in debug mode as to why it doesnt work as it will show you the …

Or you could look at Indy which comes with Delphi (unless you have turbo) and you download the HTML from the page, search through for each picture and download each picture.

Ennis has the answer, the best solution is a mutex, the runonce registry only means it will be run once on startup, not it can only have 1 copy running at any time.

Well your server version is clearly 1004, if your client says its 1000, then either you do the annoying online game style where you downloaded 1001, and restart, and then get 1002, and restart, etc.. or you keep a record of which files changed in which patches and for all …

try the keydown you have far more control then

Google is a wonderful thing.. Try looking at [url]http://www.add-in-express.com/free-addins/net-internet-explorer-addon.php[/url] as an example

OK the numbers only issue: Your reg expression of \d is why, you need to include commas and dots. for the "dont show this again" in the onchecked you set a registry (or ini file) setting to stop this, and when its missing or false, you show the message, when …

Firstly, is the c:\folder1 on the server or the client machine? If its the client machine you'd need to use file://C:/Folder1/abc.txt (that maybe file:///C:.. but cant remember) if you mean on the server then folder1 has to be accessible from you website, if its not, then either, you have to …

I dont believe c# has a function of "IsNumeric". You can use reg expresisons to test if its number, you could try parsing it, if its a single character theres an isnumber, but, I dont believe theres an isnumeric.

depends what you mean by mail library. a lot of commands are made for you and built into the frame work.

Other than its not called "Com1" under linux etc, nothing.. long as its compiled in the kernel and not in use. PS Im not saying you are calling it com1, more that windows code for com1 etc wouldnt work

Try assigning it to "MouseClick" not mousedown..

If you truely are running out of memory to do it, if the files are 75mb somethings going wrong, your app shouldnt run out of memory unless you are keeping references to mulitple copies, storing it in class that bulk out the data considerably (and i mean hugely there) when …

And the error is?

Dont include the ID in the insert statement, if the DB is set to auto inc, it will do it all for you.

Perhaps you should add rows to your D1 dataset?

Kil the whole application doevents bit, thats a sure way to tie yourself in knots. Have a list items you've queued up to go, fire off 5, as each of the 5 finish, take the next one off the queue and start a new thread. until you have nothing left …

Um, the problem is you sent your username and password as get data, not post data.

download a test file and compare times?

Yep homework or not, we arent a free set of programmers to do everyones coding for them, we volenteer to try and help you sort your own coding dilemas :)

c# is amazing at doing this, and its all built in - what do you have so far?

You could also make one yourself, if cost is an issue. An elementary query builder shouldnt be that hard to make.

In fact if you have a quick look through some of the other threads you'll find how others have approached it. You'll need 2 forms usually, a connection to the db. What code do you have so far?

Well.. Thats a very simple project to choose. Id suggest you do your own reading - as per the stickies. We are not here to do your work for you.

Thats a rather large area of suggestion - what areas of engineering are you interested in, what areas can you see anything you might feel would be worth writing an app for..

Even if you do that, the wave would be almost certainly different for each time they said it, background noises, emotion, tiredness, directionality. Normally those who want voice operated would already have a product such as dragon naturally speaking - this may help you as you can tie your program …

Dont do it that way, hide the parent form, and show the login form, if the log in fails, then close the parent, if not, show it.
