Screenshot + Send File Code (1 Viewer)

[Merforga]

This is the last part of my program that i cant seem to get work. I've attached a prototype project that I'm trying to get working. What the aim of this prototype is this:

1) Take a screenshot of the server computer.
2) the server computer then saves the screenshot into a file called "scr.dat" in the folder where the server is located.
3) This file is then transferred back to the control program on another computer and saved there.
4) Another form is used to display the screenshot in the control program.

As of the moment, steps 1 and 2 work fine, but it is step 3 i am having trouble with. If anyone can help me then that would be great. Btw, the code for the file transfer is from another program I got off someone elses code. I've tried to trim it down and convert it so it runs with my one. However, i don't really know what half the code does so if anyone can help me then again that would be great.

And the original file transfer program is as follows:

Again, any help is greatly appreciated. This is the last hurdle I need to jump over in my major project which is due pretty soon (Next friday). If anyone can help or even come up with a different way to work around this problem then I would be very grateful. Thanks in advance.

*nod*

everyone is busy with exams.

Hmm i guess i should have asked earlier then.....is due this friday ><

 

[Merforga]

Yay!!! I got it working! ^^ But there is one tiny problem. You have to do it three times to work.....when you run it once, it creates the scr.dat file, when you run the command a second time it show up a msgbox which is part of another command and then when you run it a third time it finally works. I think i can work around it but if anyone can help me debug it so that it works properly then that would be extremely helpful. This is a secondary thing, i don't really plan on doing it until i finish the other parts of the program.

I think I know what the problem is now. Does anyone know how to create a blank file when a form unloads? I'm using this current code here:

Private Sub Form_Unload(Cancel As Integer)
Clipboard.Clear
Picture = Clipboard.GetData()
SavePicture Picture, App.Path & "/scr.bmp"
End Sub

Except it doesnt work =S.....anyone know how to create a file when the form unloads itself?

Hmm on second thoughts, this doesnt seem to be the problem...the problem is that it doenst' transfer all of its data. Sometimes it does but other times it doesnt. I've chunked the large BMP file into 3kb sizes. It works sometimes but then doesnt other times. Any help would be appreciated.

lol it's strange why are you clearing the Clipboard first and then taking the contents from it?> :S

 

[dakz0rz]

He has a point there... why are you clearing the clipboard before you are getting the data?

I have already created my major..
Its a parity simulation in turbo pascal where you have to use Procedures
go me

 

[Merforga]

Its so that it can create an empty bmp file. BUt like i said, that's not the problem. The problem is that the whole file isnt transferred half the time :S.

 

[Merforga]

Ok , i know its not as important now because i've handed it in, but i would still like to find out what went wrong with the screenshot command. Heres my final project. I left the screenshot command in but you'll have to make a command button to actually send the str to take the screenshot.

Thanks in advance.

Heh sorry to say dude it was pretty flawed some parts of your application, for example locking the comp? perhaps disabling any keyboard combinations would of been good, becoz it was pretty easy to by pass, furthermore, the UI isn't too good, not as friendly, nor make much sense to an average user... however it's not a bad idea... good work non the less.

I know, i sorta left the UI till the very last minute :S. I suppose disabling the keyboard as well as locking form would have been better....i ddint think of that. Ah well too late now. Thanks ^^.

:angry: Why did you make that for your major project? An ex-student made one of them and sold it to our school. Now the teachers us it to spy on us. The good thing though, is that he made it in VB, so it is easy to reverse engineer

 

[Merforga]

Me and my friend actually have another version we made in class. I made it so that i coud mask what we were really doing. Me and my friends version is now on all the school comps. Its fun to see the peoples faces when a matrix message comes up on the screen saying "Knock Knock (Insert student name here)" ^^

My school had this program but like it was a professional program on trial but it doesn't just take screenshots, it allows the teacher to take control of the users comp as well as doing anything they desire...

 

[Merforga]

We have that too. (The professional version i mean) But the program we made also has that. I didn't include it in my program because we developed that bit of the program too late. Plus my major was only a MONITOR.
