Managed C# Compiler question - C# Discussion Boards

13-Mar-03 8:05

Has anyone succeeded in spawning a modeless dialog that stays on top of the main form, but that does not just stay on top of every window in the shell? That is, behaviour identical to Find/Replace dialogs in VS and Office.

In C++ this is routine, but in .Net I have failed when:

1) Setting dialog's TopLevel to false, and making dialog a child of main form. This only allows rendering the dialog within the client area of the main form, of course, since it is treated as a non-form child control.

2) Using Win32 API SetParent() and SetWindowPos() directly. The dialog freezes and paints garbage. CLR does not recognise Windows' way of setting parent-child relationships, I suspect, and proper message handling requires the dialog to be in the parent's collection.

I am investigating some wild hacks, but would appreciate it if anyone has insights on this.

TIA

Not sure if it's the right way, but the following works for me: Set the dialog's ShowInTaskBar property false, and after creating the dialog (in some method of the main form) call MainForm.AddOwnedForm(DialogForm).

Going from memory, the docs for AddOwnedForm say that is what it does so I would say that is The Right Way™ Smile | :)

Thank you Chris, that's exactly what the doctor ordered Smile | :)

It's a pleasure to have contributors such as yourself on CP.

Incredible that I overlooked that in the docs; probably scanned the protected methods too quickly, and got lost in keyword searches!

Cheers

I am trying to get an assembly compiled using the managed compiler and get the resulting class library strong named.

First I tried an explicite path to the file in the assembly. No go. Cry | :((

Now: the assembly info states that the strong name key must be relative to the project location....so I created the location in the assembly file as ..\..\keyfilename.snk and tried to have it find it.

I first tried just locating the strong name key file within the source files and then in the bin file and in both cases the key file is reported as not found by the compiler.

So next I added the path to my source in the /lib: switch for the compiler. This still ended with file not found. Cry | :((

Has

anyone

gotten a strong named compilation using the managed compiler and how did you get it to find the snk file ??? Confused | :confused:

I am at wits end. Eek! | :eek:

Thanks,

MJ

Is it that simple a problem?

Robert,

I was shothanding here.

if ..\.. was actually entered into the assemblyinfo file, it would fail with a compile error and never attempt to compile the dll since \. is an invalid control character.

Just put every thing in the same directory and change the assembly.cs file to point to the current directory. Smile | :)

lippie,

I had put the snKey file, and source files in one directory, and set
[assembly:AssemblyKeyFile("")] to the same directory name.

RESULT: key file could not be found

I had put the snKey file and source files in one directory and set
[assembly:AssemblyKeyFile("..\\..\\keyfile.snk")]

RESULT: key file could not be found

I had put the snKey file in the build directory and set the
[assembly:AssemblyKeyFile("..\\..\\\\keyfile.snk")]

RESULT: key file could not be found

I had put the snKey file in the build directory and directly pointed at
the build directory

RESULT: key file could not be found

I added a compile parameter /lib:"my souce library path"

RESULT: key file could not be found

I am about to put a shotgun in the mouth of the compiler and let it try and find it's brains after I pull the trigger !!!!!

I suspect that the little tidbit in AssemblyInfo where it goes after
%Project Directory%\obj\<configuration> that I am either
a) not getting %Project Directory% set
or b) I am still missing a directive to the compiler (which still goes back to a).

Sending commands between Windows applications?

19-Mar-03 10:29

I finally got the managed compiler to create a strong named assembly.

What I had to do was as follows:

1) I did a File.Copy to move the SN Key from the selected directory to the
source directory. This was my choice but not necessary.
2) Instead of setting [AssemblyKeyName...]
I had to set [AssemblyKeyFile... and specified the fully qualified path.
[AssemblyKeyFile="D:\myApp\mySource\keyF.snk"]
3) Compile to your hearts content!!!! WOOHOO!

I want my program to be able to find a specified window, activate it, and send it keyboard commands. Kind of like a macro program. How would I code this?

Have a look at the WSH sendkeys functionality.

Not the only way though... Smile | :)

How to create global variables in C#?

My application requires global variables in it(the variable that can be accessed from objects of any class in application).
How to implement such a feature ? Smile | :)

Thanks in advance Smile | :)

Create a class with static variables maybe... I dont think global variables are possible in C#.

Try something like this:

<br />
namespace MyGlobals<br />
{<br />
    sealed public class DaysOfTheWeek<br />
    {<br />
        public static int nSunday = 0;	<br />
        public static int nMonday = 1;<br />
        public static int nTuesday = 2;<br />
        public static int nWednesday = 3;<br />
        public static int nThursday = 4;<br />
        public static int nFriday = 5;<br />
        public static int nSaturday = 6;    			<br />
    }<br />
}<br />

You can reference these variables by name (nMonday, nFriday, etc.) in your other files after adding the following line:

<br />
using MyGlobals.DaysOfTheWeek;<br />

You could create an abstract super class that defines the variables that need to be global, then derive all of your classes from that one class.

Alternatively, If you don't need to update the value of the variable, then you could define it in a .config file, and then read the config file from the classes that need to access the variable. If you need to change it or share it between application types (web, windows, windows services, etc.), then define an XML document somewhere on your system and then read from and update it in the classes where you use it.

I'm sure there is probably a better way to do it, but this is my 2c.

Well said. And there are no global functions either, only statics, which preserve the purity of the OO paradigm. Wink | ;)
