Yes, but it is not recommended. If you have a requirement to do this you should really be using C++.
This is a quickie example of manipulating a string by getting it's pointer (char*)
string text = "Test";
unsafe
{
fixed (char* textPointer = text)
{
char* pointer = textPointer;
*pointer = Char.ToLower(*pointer);
*++pointer = Char.ToUpper(*pointer);
*++pointer = Char.ToUpper(*pointer);
*++pointer = Char.ToUpper(*pointer);
}
}

On top of everything else that's been said, using managed code, C#, VB.NET, or any other language that targets the .NET Framework, an item can be moved in memory by the Garbage Collector at any time. So, even though you got the pointer to item, you really cannot use the pointer because the item might not be there anymore. The pointer you have will NOT get updated to reflect the new location in memory.
However, there is a way aroudn that. It's called "pinning". The GC can be told to pin an object in memory so it can't be moved. Read up on it here[^]. Be careful. When you pin an object, you are also responsible for removing the pin when you're done with it.

So what is net60 and how does this relate to c#? Have you asked the vendor, they will probably know.

the .sis extension implies you're doing something with Symbian based mobile phones, which means you're likely to really be in the wrong forum!

First, if you don't want a share exposwed by the other machine, you'll have to use the administrative drive shares (if those haven't been removed!). That would mean you have to use the UNC path to teh machine in the form of \\machineName\C$\someFolder\someOtherFolder\filename.ext. The problem is that your code has to be running under account that is recognized by both your machine and the target machine NAD IS AN ADMIN LEVEL ACCOUNT ON THE TARGET MACHINE.

|
|
|

\\machineName\C$\someFolder\someOtherFolder\filename.ext.
if i will use this then other systems guest service creats problem
is there any API or method to accessfiles on other sytem by providing administrator username and password
for example
Access(mashinename+filesPath, adminUserName, adminPassword)
??
|
|
|
|
|
Yep. Take a look at this[^].

i can not use domain name system
i want to do it in workgroup enviornment
????
|
|
|
|
|
That's the only method you have. The "domain" would be the name of the target workstation since the admin account your use must be on that workstation. That's IF the workstation is not part of a domain.

You mean you want to make an MSI package? (by compiling your project you will get an .exe file if that is your projects output type)
Add a Setup Project to your solution in VS (File >> New >> Project >> Other Project Types >> Setup And Deployment >> Setup Project).

Hello,
First of all , i would like to thank the whole commmunity for sharing so much knowledge and i can say that i learned programming from here.
I'm a developper with a middle level working essentially in gestion programming with databases and sites.
I'm really interested in developping now a new type of program for my Windows Mobile Device, a "secured" voip application.
So first of all i gathered all the ressources about the subject , but i still block on the complexity of the workflow and don't know where to start from.
To expose it clearly here are all i found on voip & securing the media stream :
> PJSIP - Open Source SIP Stack
>Sipek Wrapper of Pjsip for Windows Mobile(Not updated anymore)
>The libZRTP library used by Zphone to encrypt media stream
My problem here is that all these libraries are first not compiled in .dll and i could not use them easily, and second there were written either in C or C++, and i'm not expert in converting all of them to dynamic dll. Of course i'm willing to develop in C# since i do not really care of performance issue, if i could make a simple call with a maximum of 2 participants (i'm aiming eventually at 4) in conference i will already considered it as a success.
If anyone could point me to the right direction or want to be part of my aventure, he'll be welcome !
You can contact me by mail or by PM on this site.
Thank you for reading me.
