how would you import this dll into your c# project?
old c style exports in the dll.
<br />
DBRESULT WINAPI dbLoginDataBase ( LPSTR lpDataBase, LPSTR lpDictionary, LPSTR lpUsername, LPSTR lpPassword )<br />
DBRESULT WINAPI dbReadSingleRecord ( LPSTR ViewName, LPSTR DataBuffer, LPWORD lpDataBufLen,<br />
LPSTR ParamBuffer, WORD ParamBufLen, RECPOS RecPos,<br />
BOOL Lock, LPDBOID lpDboID )<br />
<br />
typedef void * LPDBOID;<br />
<br />
any ideas? anyone?
Thanks!

my problem is to get the void * in there. and when to use ref and out.
i just can't figure this out on my own. call me newbie if you want. i just don't get it.

If you're unsure how to marshal a LPVOID, you could start with IntPtr ...
The Marshal class also has methods to alloc and free unmanaged memory that can come in handy in this situation.

I would use the ref and pass in a IntPtr. I think that would work, but I guess you won't know until you try.

Hi,
you can watch how this P/Invoke site[^] calls a lot
of Win32 functions; you can compare their C arguments with yours and do the same
in your code. (Make sure to check a couple of similar cases, there may be some mistakes !)
In general, if C needs an address pass a value type by reference ("ref"), or a
reference type as is (e.g. a const char* arg in C is a string in C#).
If C needs an address of an address (not often) pass a reference to a reference type.
If native code needs to write to a string argument, pass it a StringBuilder with sufficient
Capacity.
etc etc etc

Hi, I'm developing a MediaCenter Type of Application. There seem to be two options for playing Audio/Video using Media Control Interface (MCI) and DirectX. As I'm new to C# can you tell me which one should I choose and their respective benefits. My primary concern is that whatever I choose should put minimum load on the system. I'm open to other suggestions as well.
Thanks...
P.S: I havent particularly liked the approach required to use MCI.

Erhm, i'd recommend DirectX. For now you can use it for just playing tracks, no problem, you can also use MCI instead. But if you'd like to expand the possibilities of your app, you'll be stuck to the MCI limitations.

Hi,
I have seen from the PetShop .NET project that they have the following method for creating salt:
private string GenerateSalt()
{
byte[] buffer = new byte[SALT_SIZE_IN_BYTES];
(new RNGCryptoServiceProvider()).GetBytes(buffer);
return Convert.ToBase64String(buffer);
}
SALT_SIZE_IN_BYTES = 16. Is this the best way to do it? Is this how the default membership provider does it?
Regards
ma se
|
|
|
|
|
That's about how I do it. Don't generate a salt size too big otherwise you'll end up with a Base64 string the length of a aircraft carrier. I find that 10 to 20 bytes is sufficient.
I just got done explaining this to someone else, here[^].

I having a weird problem with remoting and I think it is due to Symantec's firewall that we have installed on all our computers as part of IT's standard setup. In my application I have a remote object that the server publishes using RemotingConfiguration.RegisterWellKnownServiceType. The server then also gets a copy of the object itself using Activator.GetObject. This works fine if I'm connected to our corporate network. However, when I'm disconnected it doesn't work. I get a message that the "No connection could be made because the target machine actively refused it". The weird part is that once in a while, it actually does work!
I checked out our Symantec firewall (which I can't change settings on) and watched it as I tried to connect and I notice that the number of blocked inbound connections does increase when I attempt to start my server (but the number of allowed connections also increases). When I'm connected to the network, I don't get any increase in the number of blocked connections. Digging deeper, Symantec has a category called "Blocked unmanaged TCP/UDP inbounds" which increases when I try and start my server while off-line.
Does anybody know what it means by "unmanaged" in this context? It seems like the server registering the well known service type is accepted but the attempt to connect to that well know service is not. Is there a way to convince this POS firewall that it should allow my connection?
I'm totally screwed if I can't find a way around this

Have you figured this one out?

Actually, I just did. It seems that if I set rejectRemoteRequests when I create the TcpChannel on the server the firewall doesn't block it anymore. So I think the solution is to check when creating the server to see if I'm online and if not set rejectRemoteRequests and assume that the client has to be on the same computer (which it does, because we're offline anyway).
The only problem I see with this is if the computer was not connected when the server starts, but is then connected later (or vis-versa) but I don't think that's something I'm going to worry about.
It still mystifying as to why the firewall blocks activity on a port when not connected to the network, but has no problem with it when you are connected (and it could actually be a malicious attack).

That is really odd

I want to declare the object of a class at run time. For example if string str="schedule" then declare the object of Schedule class and pass this string to its construction.
Is there any way to do that? Please tell me the solution..

This can be done using reflection. Plenty of good article online, just google C# reflection

I did google on this. The only thing I got is that you can get the type and member info of a class. I couldn't find any way to declar the object of a class at run time.
If you know the code, please write it.

You can use either Activator.CreateInstance() or Assembly.CreateInstance()
