Hi:
I am trying to invoke a base class method, but I find I can only walk down 1 level of inheritance. Is there a way to go down more levels with some more explicit way of specifying which level I am interested?
eg.
public class a
{
protected virtual void Method1()
{
...
}
}
public class b: a
{
protected override void Method1()
{
...
}
}
public class c: b
{
protected override void Method1()
{
...
}
}
public class d: c
{
protected override void Method1()
{
...
}
protected void SomeMethod()
{
....
-- here I want to invoke Method1() of class b
base.Method1(); // this would invoke c.Method1()
}
}
Regards, smurfy

That is correct. You call the imediate base, which calls the next base and so on. Skipping a class is not recommended and probably suggests that your design isn't quite right.

I have a dll that is written in c++ and I want to send a char *. Pointer of array of chars.
So, I need a equivalent of:

some_function(path);
for C# application.

Hello
Send it as StringBuilder .
Regards
|
|
|
|
|
Can you provide some code sample for this?
I've tried, but no luck.
|
|
|
|
|
Hello
StringBuilder path = new StringBuilder();
some_function(path);
Regards
|
|
|
|

Iam sorry, but I haven't managed to solved this.
When I do as you said, I get an errors:
C:\Backup\Development\Current Projects\BlackBox\frmMainForm.cs(980): The best overloaded method match for 'bb.bbox_table_open(char*)' has some invalid arguments
Pointing at: bb.bbox_table_open(s);
And
C:\Backup\Development\Current Projects\BlackBox\frmMainForm.cs(980): Argument '1': cannot convert from 'System.Text.StringBuilder' to 'char*'
Pointing at: s in functions parameter. (s is StringBuilder s = new StringBuilder())

how do you import the unmanaged code in your C#?
Regards
|
|
|
|
|
Through DllImport.
[DllImport("bb.dll", CharSet=CharSet.Auto)]
[return: MarshalAs(UnmanagedType.SysUInt)]
unsafe public static extern uint bbox_table_open(char *archive_path);
|
|
|
|
|
Hello
Why do you declare it as unsafe? I belive your declaration should be this
[DllImport("bb.dll", CharSet=CharSet.Auto)]
[return: MarshalAs(UnmanagedType.SysUInt)]
public static extern uint bbox_table_open(StringBuilder archive_path);
Try it! Otherwise you'd have to make an unsafe bloock in your code and create tha char* inside it.
Regards

Now is good. Now it compiles and function now work.
Unsafe was becouse in prototype function (parameter) was char *, but now it makes sense.
Thank you.

Hi. Does anyone know how to access the Windows system color by code? (The one set in the control panel)
[edit: ...Ok. I think it's SystemColors.AppWorkspace; But the MSDN was very, very ambiguous in their description. Sorry for wasting anyone's time]

The SystemColors class ?
-----------------------------------------
|
|
|
|

Sorry that my question was kind of non-descript. I'm trying to get access to the background color of an MDI parent. In the MSDN documentation for MDI, it states "be aware that the edge of the MDI parent form will pick up the system color (set in the Windows System control panel), rather than the back color you set using the Control.BackColor property." I want to know where Visual Studio gets access to this color and how I pick it.

Hi,
I have a process that batch prints reports to the default printer on a client
machine.
However some reports are longer than others so it would be useful to know
when the printing of each reports is complete (at least in the eyes of the driver/spooler...)
Is there a way using C# where I can check the state of the current job therefore
delaying the printing of the next item?
It would also help with delaying printing when the printer has run out of paper etc...
Thanks in advance.

I have the need to output text to a file in which when its printed on a pre-printed form, the values in the outputted text file will match up with the boxes on the form. Like an automated typewriter of sorts. I'm doing this so far with the System.IO namespace. The issue i'm having is the space between carrage returns. I'm using a char[] and creating 5000 ' ' char in it and ever 80 chars i'm putting a '\n' char. Then using that to insert at a specific point in that char[] so when it prints its on the specified line and distance from L to R. But on a carrage return, there is a default gap, that gap is throwing off some of the lines. Does anyone know how to correct this, or have a better way of achieving this?
Think of it as a Doctor form that is preprinted blank... and I need to access data from a database and write it to a text file in such a way that when the text file is printed on this preprinted template... the outcome is matched up like you did it on a type writer. Make sense?
Thanks in Advance,
Scott
