Good day, please help.
I have this program I'm busy writing and I have no clue how to do this: when a user starts a program, I want to "intercept" and "pause" the program while its loading and prompt the user to "ALLOW" or "KILL" the program. If anybody has used Kaspersky's Internet Security, it is implemented in there - an alert pops up prompting the user to allow the program to finish executing or cancel it.
Please help, charles

I posted a tip on using subsequent forms from the app class. Have the first form be the spalsh panel (or whatever you want to call it), and code accordingly. The splash panel would spawn a thread that performed the startup code, and if startup completed before the user pressed the cancel button, the first form would close and the 2nd form would be displayed.
Here's my tip:

I have an app for a headless Win CE device written in C# using VS2005. Can anyone tell me how to reboot the device from within my code please?

Application.Restart or start a new instance of your program and use Application.Exit to end the current instance. Or run a different program that detects if an instance of your main program is running (perhaps by looking through the names of all the currently running processes), start that up, end your current program, at which point it will start a new instance, after which that extra program will close itself.

Thanks, but I need to re-boot CE, not just restart my application.

Can any one tell me, How to configure and use Enterprise Library security application block in .NET windows application?
Any example will be more helpful.
|
|
|
|
|
| I suggest you read the Enterprise Library documentation, the process is too involved and too implementation specific (i.e. we don't know what you want to acheieve with the library) for you to get an full answer here. If you have a specific problem setting up the blocks then post it here. Dalek Dave: There are many words that some find offensive, Homosexuality, Alcoholism, Religion, Visual Basic, Manchester United, Butter.
Pete o'Hanlon: If it wasn't insulting tools, I'd say you were dumber than a bag of spanners.

Thanks for reply,
i read Enterprise library there are some example to implement security block in web application also, there are so many example at different sites to implement Security application block in web Application, but if we want to
achieve the same thing in windows application using enterprise library, then
How can we?

How to create dynamic objects in C# in Runtime.
For example, I will list no of drives present in a System if it is 6 drives i have to create 6 Different objects can any one help me regarding this...
string []drives=GetLogicalDrives();
for(int i=0;i
|
|

This is basic stuff, you should read a C# book as you will get a much more detailed explanation than we can put here (and probably easier to follow):
In your example:
string[] drives = GetLogicalDrives(); Returns an array of strings, each containing a name (lets say) of a drive.
Use a foreach loop, rather than a for loop - you don't need to know how many drives there are.
foreach (string drive in drives)
{
DriveInfo di = new DriveInfo(drive);
... do something with the drive.
}DriveInfo is a class which I invented to return info about a drive given its name. Each time you deal with a different drive from the drives array, you create a new instance of DriveInfo to handle it, with the new keyword.

Yes, yes, I know! 
Just using it as a sensible name for a class the OP might want to implement to go with the "drives" array they already had.
I dunno, .NET has taken too many of the good names already, why can't they have used DICFMSTOMYLH instead, and left all the good ones to us? They used to in the early days!

hi,
i have a char array in which i m getting path of current module.i want to convert it into string before loading it.hw can i do that?
|
|
|
|
|
Just use the constructor of string which accepts char array - here[^].
Example:
char [] charArr = {'A','B','C','D'};
string strFromCharArr = new string (charArr);
Regards

char[] charArray = new char[22];
string str = new string(charArray);
