The current project I'm working on is a Windows form app and I would like it to have a display of the time and date on the upper middle of the form, a text progress that will display messages (drive is being opened, closed, etc), then at the bottom I would like three buttons...an "Open Drive", "Close Drive", and "Exit Program" buttons. Obviously I would like each button to do what it says, then a message that displays what the program is doing (Now opening CD-Rom Drive, Now closing CD-Rom Drive, Now Exiting Program, etc) after a button is pressed while the program is carrying out its task.

I am thinking of more things to add to the program like maybe a data log or something that the user can check within the program that keeps itself updated or whatever. any suggestions would be awesome, what do you think?

And Im sure with time I can figure out and code everything on my own but I may need some help being pointed in the right direction...however, I will try my best!

Thanks :)

I would suggest getting that to work first, then adding fun stuff. It doesn't seem trivial.

Ok so when I post code for a windows app button that is supposed to open the cd drive under "button1" and then the code that closes the drive under "button2" it makes all the buttons on the form disappear...I would guess Im posting the code in the wrong spot...so my question is where exactly do I post the code for the buttons?

[RuneNova91]

It might be very simple but it's not clicking for me :( can someone help me out? I need to add code to make my buttons actually work...where do I post the code for it?

You can post code in one of two ways

1) use code tags [noparse]

 /* your code goes here */ 

[/noparse]

2) zip up the project files (delete all files that are compiler generated) then attach it to your post. You have to use the Advanced Editor to do that.


>>I need to add code to make my buttons actually work...where do I post the code for it?
In the Design Editor double clikck on the button, the IDE will create a function (called an event handler) for you where you can add code to make that button work.

Right now this is the windows application with only button1 on it and the button has no function yet...I want to post a code that makes the button open the cd-rom drive. then Ill make a few other buttons to close it, exit the program, etc. I just need to know where to put it...unfortunately I've only made win32 applications so the windows form is kinda foreign to me...also just fyi, im using visual c++ 2010

[Ancient Dragon]

you don't manually put it anywhere. As I said in my last post, double click the button and the IDE will start the function for you. All you have to do is add the code to open and/or close the CD drive. Don't ask me how to do that because I don't know. You will just have to google around and see if you can find some C or C++ code that does it.

[RuneNova91]

yea thats what I mean. Everythings set up for the actual wfa. I just need to make the button do what its supposed to do. I just dont know where to add the code

[dbug]

Ancient Dragon is telling you where you need to add the code using the IDE. You must go to the view where you design the form graphically. There you must double click over the button of the form that you want to use to open the cd-rom or whatever. When you do this, Visual Studio will automatically create a new function and put the cursor inside that function so that you can write the code. This is the place where you must write the code to open the cd-rom.

ah crap I knew it was very simple. sorry for the misunderstanding. thank you so much, ill continue working on it
