first of all, tank you for paying attention to this problem and then, what do you mean plug the c++ function into java class ?

Areff 18-Oct-12 3:14am View

no, but i hope to someone could give a concise explain about the whole algorithm of this C++ function.

i think it will fill the data area (i have not access to source code of ReadData function)

Areff 22-Feb-12 3:34am View

ReadData modifies it , and actually ReadData is responsible for reading data from a device and i havenot access to it's code , i just use it and it is working as well as expected in c++ app , it works in P/Invoke but in end of execution and in it's marshaling state error happend.
i changed the code as this code :

[UnmanagedFunctionPointer(CallingConvention.StdCall)]
public delegate int ReadData (ref StringBuilder data);

IntPtr readAddrs = NativeSupport.GetProcAddress(dll, "ReadData");
ReadData read = (MS_Read)Marshal.GetDelegateForFunctionPointer(readAddrs, typeof(ReadData));

StringBuilder d = new StringBuilder(200);
read(ref d);
/"Attempted to read or write protected memory. This is often an //indication that other memory is corrupt."

but error occurred again. using both ref and out ends with same result (the error).

you absolutely right , the problem is clear to me now because i found that the infrastructure of network doesn't works fine , and my approach to loading the DLL using GetProcAddress, LoadLibrary is OK, and i tested your solution the using of P/Invoke will works fine too. tanks for your help.

I have not problem in compression or other things related to fetching the images , my question is about performance of fetching speed of sql server against file system, which one is more faster ?

I think this must happen in network levels, and a service must be used for this problem,

Please experts
help about this ...

i have not access to the client app's code and cannot change it, then i can not use WCF , i want to an app or service that i could put it between client app and the reciver app, ofcourse the 3rd party app or service must be in client machine to encrypt data(message) before getting out of machine (to network).

i mean it, that app's authentication works fine and when some user logs in , he/she can view the authenticated pages .

i solved my problem by removing membership & profile tags from web.config.

I asked from my host , they said that if your site has not annonymous access it can not be accessible. and your site has annonymous access.

Areff 28-Oct-10 17:16pm View

No, everythings is ok with forms authentication , my problem is that when i trying to see the default.aspx , where it is excepted to view by all with site url , i prospect to view default.aspx when it is specified to be a default document in web.config, but url redirect to login.aspx insted of default.aspx .
