I would suggest you check into Code Access Security[^] (part of the .NET Framework Developer's Guide). Using the .NET Framework 1.1 snap-in for the Microsoft Management Console, you can evaluate what permissions apply to a particular assembly under the "Runtime Security Policy" and then selecting "Evaluate Assembly". Within the security policy section you are able to make many other changes as well as adjusting the security zone and increasing the level of trust for a particular assembly. This should get you started.

Hello.
I have a web C# project with a form with 3 buttons and 3
placeholders, each placeholder contains a Web User Control,
when I click over button 1 it shows the data of WUC1, when
I click over button 2 it shows the data of WUC2 and when I
click over button 3 it shows the data of WUC3. My solution
was to make initially invisible the 3 placeholders and when
a button is clicked then I made visible the corresponding
placeholder, as the following code from button 1 shows:
this.PlaceHolder1.Visible = true;
this.PlaceHolder2.Visible = false;
this.PlaceHolder3.Visible = false;
This works well, but I think it's not too eficient to have
loaded the 3 WUCs, so I'm trying to make a dynamic load of
each WUC depending the button clicked, example of button 1:
private void btn1_Click(object sender,
System.EventArgs e){
this.PlaceHolder1.Controls.Clear();
this.PlaceHolder2.Controls.Clear();
this.PlaceHolder3.Controls.Clear();
this.PlaceHolder1.Controls.Add(LoadControl("WUC1.ascx"));
//Only load the WUC1
}
This code load well the WUCs, show the data, but it can't
execute the events of the WUCs, because in each WUC I have
buttons that perform some operations and this events don't
execute, i put a breakpoint and show that the page_load of
the page that contains the WUCs, I think it's a problem of
dynamic load of controls, any idea would be appreciated.
Thanks a lot.

Hi all,
After I loaded a dll component(c#)and use it in the program,
how can I destroy it(remove it from memory) in C# ?
Thanks

You will need to load the assembly into another AppDomain[^] and then use the static method AppDomain.Unload to remove it when you are done.

I have this code in a C# class library
[Conditional("DBC_CHECK_ALL")]<br />
public static void Assert(bool assertion)<br />
{<br />
ExceptionAssert(assertion);<br />
TraceAssert(assertion);<br />
}<br />
<br />
[Conditional("DBC_USE_EXCEPTIONS")]<br />
static void ExceptionAssert(bool assertion)<br />
{<br />
if (!assertion) throw new AssertionException("Assertion failed.");<br />
}<br />
<br />
[Conditional("DBC_USE_ASSERTIONS")]<br />
static void TraceAssert(bool assertion)<br />
{<br />
Trace.Assert(assertion, "Assertion failed.");<br />
}
which is attempting to implement Anding of attributes as per this topic
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/csref/html/vclrfconditional.asp[^]
However, when I define either or both of DBC_USE_EXCEPTIONS or DBC_USE_ASSERTIONS in a Console app. that uses the library neither ExceptionAssert nor TraceAssert gets called.
Note: when all this is done within a single console app. it works OK.

In .NET Compact Framework, System.Threading.Monitor.Wait(Object obj) and
System.Threading.Monitor.Pulse(Object obj) are not available. Does anyone know to use these functions or replace by other functions in .NET Compact Framework? Really Thanks a lot!!!!!

Hi everybody,
now for something completely different 
I just read an article on pathfinding here on CP(http://www.codeproject.com/csharp/CSharpPathfind.asp) but it did not really get me started as I am too dumb to convert this to 3D
MY PROBLEM:
I have to write a program which checks if there is a path through a threedimensional cube, which consists of smaller cubes (scubes)
The cube dimensions are fixed (20x20x20 scubes) and each scube may be filled or void.
The is one variable, p, which determines the probability of a scube being filled (p) or being a void (1-p). This does not change as we iterate through the scubes on startup.
I have this cube ready to go and should now determine if there is a path from the top side to the bottom side.
Movement Rule: No Diagonal Moves, only along the three axis.
I smell recursion here, but I can't figure out how to do this 
If I had some Lego(tm) here, I might have BUILT a cube and found a solution, but right now all I have is one sheet of paper and a pencil.
Can anyone get me back on track?
Cheers
Sid

So, what's the qustion? And, no, we're not going to write the code for you. If you're having a problem with the logic or some code issue, we can help with that. But don't expect anyone to write the whole thing for you.

Hi! I’m working on a simple Windows.Forms database project. It would be nice for me to work with DataGrid (set properties & behavior of its elements) mostly via designer. Before setting DataSource & DataMember of the DataGrid I need to fill relative dataset with data. For that purpose I call myDataAdapter.Fill method.
The question is: Where can I paste myDataAdapter.Fill method to get filled DataGrid in the designer?
I’ve tried to put fill method in InitializeComponent, but designer recreates this section every time I change any property with it. Putting fill method somewhere in myForm constructor takes no effect on the designer. So maybe there is an attribute saying [no recreate] to mark constant section of designer region?
Thanks!

I might be wrong but I'm practically sure u can't make a DataGrid's databinding "active" in design time.
|
|
|
|
|
As long as the dataset exists and the datagrid's datasource property is set, filling the dataset in the c.tor has always worked for me... maybe paste some code (including your initializecomponent method) and it would be easier to see your problemo.

So, there is no special attribute for designer region. That’s ok. Maybe I've pasted fill method to the wrong constructor.
Let’s simplify my question, so there is no need to paste a lot of code.
Now I have a form & a button. There is my form constructor.
public Form1()<br />
{<br />
InitializeComponent();<br />
this.button1.BackColor = Color.Red;
}<br />
Initialize component is fully generated by designer and not takes a point of interest for us.
Please help me. In which class constructor I've to paste "this.button1.BackColor = Color.Red" to have colored button in the designer?

As far as I know, you cant create any method that the designer will run when creating a new instance of the control/component. It only does that with InitializeComponent() and it must be hardcoded because the method doesnt have any Atribute to tell the designer to run it in design time.
The only way u might be able to achieve what I think you want is creating some Browsable Get/Set property and putting the DataSet binding code in the setter. Then create a new form inheriting from the one u just created and go back to the designer and change the derived form's property. That should run whatever code you want.
Haven't tested it, but it should work. I dont know what the use in doing this is unless u want to get a better idea in design time how ur DataGridStyle is looking when displaying data but  ...if thats the case, once it looks good just copy all generated code to ur original form and ur set.

How can I allow the Form to only do paint and move, resize, maximize and minimize events? I have the code for paint below.
private const int WM_NCPAINT = 0x0085;
private const int WM_PAINT = 0x000F;
private const int WM_ERASEBKGND = 0x0014;
private const int WM_PRINTCLIENT = 0x0318;
[SecurityPermission(SecurityAction.LinkDemand, UnmanagedCode=true)]
protected override void WndProc(ref Message m)
{
if (this.Buzy)
{
if (!((m.Msg == WM_PAINT) || (m.Msg == WM_NCPAINT) || (m.Msg == WM_ERASEBKGND) || (m.Msg == WM_PRINTCLIENT)))
{
return;
}
base.WndProc(ref m);
}

try this:
private bool allowPaint = false;
protected override void OnPaint(PaintEventArgs e)
{
if(this.allowPaint)
{
base.OnPaint (e);
}
this.allowPaint = false;
}
protected override void OnResize(EventArgs e)
{
this.allowPaint = true;
base.OnResize (e);
}
protected override void OnMove(EventArgs e)
{
this.allowPaint = true;
base.OnMove (e);
}

Hi
I had an resorce in my Assembly (Bitmap) and need to get resource ID of one, for pass to an function.How i can do this??
Please help!!!
|
|
|
|

There's no resources IDs like with native images - they have the name that you gave them when you compiled your assembly.
To get a list of the names, use Assembly.GetManifestResourceNames. To actually get the stream, use Assembly.GetManifestResourceStream.

I am trying to convert project originally written in SDK to .NET and came accross a problem that SetPixel function is not available anymore in .NET's GDI+. The function in original code was used to paint a grid (or I should better say a dot matrix) in a sort of a vector editor.
The SetPixel function is available in Bitmap class, but that won't help me, I guess.
Of course to draw a line just 1 pixel long does not work,
thus I would like to ask for any suggestion how to realise this in .NET

Probably easiest to just create a Bitmap, draw to it using SetPixel, then render it to the window (or whatever you have) using GDI+
