I have read a lot of books on C#, but what I am ultimately looking for I have yet to find. 1st I would like a book on explaining good practice of creating classes and explains inheritence. Next, I would like a desk reference, with good explanations and examples ( unlike MS Documentation ) for C#.
Thanx in advance

I am dynamically connecting to an unmanaged C++ COM interface using GetTypeFromProgID, but I must get a secondary IDispatch interface by calling the "GetBasicCallInfoIDisp" function of that interface. Using this secondary interface, I am trying to get a simple property.
The JavaScript is very rudimentary:
var winoperdoc = new ActiveXObject("WinOper.Document");<br />
var winoper = winoperdoc.GetBasicCallInfoIDisp();<br />
window.alert(winoper.SeizureID);<br />
The C# version I have looks like this:
Type objWinOper = Type.GetTypeFromProgID("WinOper.Document");<br />
<br />
object objWinOperLateBound = objWinOper.InvokeMember("GetBasicCallInfoIDisp",<br />
BindingFlags.CreateInstance,<br />
null, <br />
objWinOper, <br />
new object[]{});<br />
<br />
int SeizureID = (int) objWinOper.InvokeMember("SeizureID",<br />
BindingFlags.Default | BindingFlags.GetProperty, <br />
null, <br />
objWinOperLateBound,<br />
new object[]{});<br />
This compiles, but I get an "Unknown Name" when I try to get the value from a member property.
Any help is appreciated.
Cheers,
Daaron

- how I can add more image in pictureBox ?
- how I can move image in pictureBox with mouse ?

You cannot add more than one image to a picture box. You can, however, add multiple picture boxes to another control such as a panel.
The picture box control doesn't contain any functionality for moving pictures within it. You can do this yourself by watching for when the user drags the mouse, then move the picture box itself.

Boo! Do your own homework. The only way to become a good developer is by solving problems on your own. Do you know what companies do with people who don't do their own work...they promote them! But that's beside the point...

Is it possible to open Shared Memory in a C# Windows application? specifically, Shared Memory created in a C++ app using the CreateFile, CreateFileMapping API.
(& if it is possible, can I get a hint where to start looking for the "instructions"?)

There is an design paradox here: To have this event, you need to click the buttom which forces the focus onto the button. If it was anywhere else, you wouldn't be able to click the button.
You don't want things stealing focus while doing various operations (like clicking, drag-and-drop, etc) anyway. You should consider another UI design instead of trying to have focus jump around on the form while performing user input.

Use the form's Select() method or ActiveControl property instead.

U can use Javascript client side scripting for setting focus

Hello,
I want to add names coming from my database to be coupled to the Text of buttons.
The number of names is variabel (depending on grade of filtering).
So I wanted to build a loop for adding the names to the Text of the buttons.
<br />
for(i = 0; i < total; i++)
buttoni.Text = "corresponding name from tabel";<br />
The "corresponding name from tabel" is no problem, but I want the i from the for-loop to be used in the variabel name for the assignement of the text. (which you see very hard-coded in the code)
But I always get errors, no matter what i try ..
Can somebody help?
Allready thanks!

What errors do you get?

That doesn't really matter i think (i tried different things).
I just need a way to form a variabel with a part (button) and the content of a variabel (i), which makes button1, button2, button3, ..
The errors are like "The name 'buttoni' does not exist in the current context" but that seems pretty obvious I think ..

Have you tried something like:
int n = x; //x being your number of buttons
Button [] buttons = new Button[n];
//remember to create every button individually.
//so far it's just an array for holding buttons, but no individual buttons.
string [] buttonStrings = new string[n]; //or use your tabel
for(int i = 0; i < n; i++)
{
buttons[i] = new Button();
buttons[i].Text = buttonString[i];
}

Hmm, that's not exactly what I'm looking for.
This is a sample:
<br />
int totaal = this.aanbodTableAdapter.CountFrisdranken().Value;<br />
for (int i = 0; i < totaal; i++)<br />
{<br />
button[i].Text = aanbodTableAdapter.GetFrisdranken().FindByid(i).ToString();<br />
}<br />
button[i] gives errors, also buttoni, button{i} etc.
Somebody?

button[i] is the right way to access an element of a button array. WHAT ERROR DO YOU GET!!! Copy/paste it out of the IDE.

I don't really understand what you mean ..
I haven't got an array, only seperate buttons which are created in the design-mode with names like button1, button2, etc.
|

If you know the names of the buttons then all you have to do is write a switch (or if/else) block and set the Text property of the button you wish (inside the loop).

Yeah, that would be the most obvious, but ..
If I have 50 buttons which have to get a name, it's quiet a job to write the code, and it's also a lot of useless code, because it would be much nicer/easier/etc. with just a loop.
+ the fact that you don't know how much buttons must be named ..
