Hi!

.NET Framework is a must. Period.

Once that's installed, however, you usually can just copy all the DLLs and EXEs from your build directory to an arbitrary directory on the other computer and it should work.
That's called XCOPY deployment, btw.

C# How to modify the Z Order

10-Apr-05 3:04

DateTime.Now is correct, but the formatting is a mess...;P

DateTime has many wonderful (and culture-sensitive!) methods for formatting the output, there's no need to use 12 lines when you can simply write

string t = DateTime.Now.ToString("dd/MM/yyyy");
string t2 = DateTime.Now.ToString("HH:mm:ss");

I am using Graphics to draw a rectangle to indicate a new location of a control as the users move the cursor around.
Now the thing is my rectangle, when moving over other controls, is covered by other controls. How do i change the z order of the graphics so that i can see the whole rectangle while moving it over a control?

Thank you so much for reading and please help me out

how to implement WHITEBOARD which can support many users??

10-Apr-05 3:12

There are two methods inherited from Control to perform this:
BringToFront() and SendToBack(). They do what their names imply.

The SDK contains C# help and C# samples. If you don't see them, you've not downloaded the latest SDK. Actually, I think when you install the SDK you need to choose the managed stuff. Certainly when you install the runtime, you need to include the /manageddx switch, or you get nothing.

Reading drive letters?

Is it possible to get leeters of the drives of the system, but only hard-drivaes (no cd, dvd etc)? I only could find a method that reads all system drive letters no matter what they are.

Take a look at the System.Management namespace.
With a WMI search like "select * from Win32_Volume" for a ManagementObjectSearcher you can get all the volumes attached to the system and then query their properties.

Help with a Dental application...

10-Apr-05 4:54

Since you want specific drives, you would have to check the drive type. The way I would do it is by using the System.Management namespace and execute a WqlEventQuery to check the drive type (e.g. type 5 means it's a cd-rom). Check
this[^] for more info. Hopefully it will clear a bit things out for you.

i got an application that contains a text box, i want to draw lines depending on the TextBox input. I know how to draw, but how could I make the drawings dependent on TextBox input.
thnx in advance

You could elect to only draw the lines after there was input from the user, and you could use the user's input to determine where to draw the line?

Why not provide text boxes for start and end coordinates, and a button to initiate the drawing of a line. By pressing the button, the user would be indicating that they are satisfied with their origin/termination coordinates. The logic to draw the line would simply convert the text input from the user to integer values, and use those values when rendering the line.

Hello,

I am trying to upgrade an existing Dental application by adding visual-representation of the human jaw, and allow the user (dentist) to be able to color each tooth. (For instance, a red sign on one of the tooth's corner would designate a filling).

More specifically, I need to find resources for finding out the best way for:
1. Representing the jaw (e.g. a bitmap for each tooth, or one bitmap for the whole jaw)
2. Being able to actually paint different parts of each tooth with different colors
3. Being able to store the new drawings for each tooth in the database with the rest of the patient's info (MS Access DB)

ANY help from anyone who had to do something like this before, or anyone who has any ideas would be greatly appreciated.

Thanx

Polis

Sounds interesting. In how many dimensions you want that visual representation? 2D or 3D? (assuming computer will have some better graphics card)

From the top of my head, I'd say #3 you don't store anything... draw it from information already in DB, no? There is no need to store information twice. Or do I miss something?

Since this is purely a Dental application, there is no need in over-complicating things, so it's going to be a 2D visual representation (at least for start Big Grin | :-D

)

Regarding my #3: The user (dentist) will have limited options in the designs he/she can do on a tooth (for instance, 1 specific design for a filling, or a big red "X" sign over a tooth designating that the specific tooth is absent on the specific patient). It won't be a free-hand painting or something like that. Therefore, a there is a table in the DB which contains all of the possible designs and each time the doctor alters a tooth, that new (predefined) design will be stores in the patient's table as well.

Hope I've clear things a bit.

hmm my understanding is that there already is DB with information like fillings/missing tooth etc. for every tooth. (As you said you want to do visual representation, not to rewrite DB schema Confused | :confused:

) So you'll take these information from DB and render jaw from information you have there... example: in DB is that user #123 has one missing tooth at position 5 (or something, dunno). So you have somewere bitmaps for tooth OK, tooth with filling, missing tooth etc. ( not for every patient, only once!) and render all of them according to information form DB. After some change (e.g. on visual model you right click and set filling for tooth on position 7) you change this information in DB, like you did without visual representation. Maybe some kind of misunderstanding is going on?

Yes David, what you are saying is making sense to me. You are right, I got the whole thing wrong in my mind.

So, what you are saying is that I keep a folder with all the possible bitmpaps for each tooth. Then, in the application the doctor selects the bitmap for the specific tooth (e.g. by right-clicking on the tooth) and apply it. Then, this change is saved in the Patients table for the specific patient (e.g. by saving the bitmap filename). Correct?

However, I am still wondering what is the best way for representing the jaw thing on the form. What do u think? A series of bitmaps (1 for each tooth) would be solution that fits the above logic right?

Any ideas on where I can get some resources? e.g. all-ready made bitmaps of a human jaw etc? Cause my research didn't really pay off.

Yes. There are only about 32 * number of "designs" of them so no big deal I think.

Almost correct. I don't like bitmap filename semantics here. You (should) want to represent state of tooth, not picture. In simple model, you'd have table like
- left_upper_filling | left_upper_filling.bmp
- rigth_upper_filling | rigth_upper_filling.bmp
.... something lke that. Point is whan you have table like this is you can change your pictures from bmp to wmf or something only on ONE place in DB. Plus if you take advantage of transparent pictures you can easily blend some images together, e.g. to make tooth with two fillings on different sides or something like that.. I don't know, there is midnight again so I may not be 100%

I still don't know how you want result look like... Something like this[^] ?

Oh wait... do you want to use real pictures of patient's teeth? I doubt it, but it would be ideal way IMO. ( but nobody's gonna pay it nor make photos of patient's teeth on every change, keep it real Dead | X|

)

Google Image search? Mostly copyrighted material I guess, but in general you should find medical/scientific sites and there you may eventually ask them for some material... hard to say.

I don't know how much you want to spent on it or even how much freedom you have, so some of my ideas may sound crazy. But I better write 'em down then forget them.. what if they were useful? Big Grin | :-D

p.s could you post screenshot of your result one day? It would be cool! Cool | :cool:

Or article maybe Smile | :)
