• edle Sending Message to a known IP

  I am asking how to send message to a known IP.

I want to send a string text and picture You'll have to be much more specific... what kind of message do you want to send Via what sort of protocol Use a Socket cla ...Show All

• Raymundo Chapa94595 Release bin doesn't run outside VS2005

  Hi, I have a pretty big project C# under VS2005. I work on it from 2 years, and from 1 year on VS2005. Since middle f this month, the release binary is not working anymore outside VS2005. I can still run my project from VS2005 in both Debug and Release mode.

• prashanthkumarhv hashtable.values.CopyTo() function

  Hi Guys, I am trying to convert the values in my hashtable to an array. I am using the hashtable.values.CopyTo() function but it always breaks, it doesn't seem to matter if I change my array type. The data in the hashtable is a [,] and i would prefer to keep it that way, however I know that I may have to change it to a double[ ] (conincendentaly I have done that) but I still get a error on the lines it doesnt fit. Can someone please help. I have pasted my code below. double []meanR = new double [7]; theMeanReturn = mean.getMeanCcyReturns(TheReturns); // theMeanReturn returned as a [,] double [] TheMeanReaturn = new double []; //parse theMeanReturns to a [ ] for ( int p = 0; p < theMeanReturn.Lengt ...Show All

• chare Missing DWMAPI.dll causes problem with COM interop in c#

  I have recently installed IE7, and am now experiencing a problem with COM interop in one of my c# projects. It seems that there is a dependency on a dll called DWMAPI.dll from the COM dll. I have read a bunch of posts about similar problems, and it seems this dll comes with Vista, but is missing on XP machines. For some reason, installing IE7 makes it become a dependency for things like .NET interop. The only solution I have been able to find in the forums and posts is to uninstall IE7. Microsoft has not yet posted anything that I could find in regards to this issue. Does anyone know something I don't Any help is greatly appreciated. Thanks, Dan This thread suggests that the real problem is wit ...Show All

• Dipendra Calling Win32 API from Assembly Language

  How do I call a win32 API function from assembly language Basically I need to call functions from kernel32.dll from assembly language. Win32 APIs are just stdcall C functions , so this is a specific instance of a more general question: how to call a C-function form another DLL w/ stdcall calling convention from assembly. In general, The easiest way to answer "how do i do X" in assembly is to do X in C and then look at the generated assembly from the C compiler under a debugger (in Visual Studio, you can right click and do "Show Disassembly". The exact syntax will depend on your assembler. SachinPatole Please bear in mind that I am very biased, having written a suite of free tools to write ...Show All

• Antonio Neeves HttpWebrequest Post

  Hello Im trying to upload a file to a https address using the getRequestStream method of the httpWebRequest class. The code appears to work fine and no exceptions are thrown, but the file does not appear to have uploaded to the server. The stream is working as it should. The server requires authentification via a public key, which i have and is installed. I have used the CreateFromCertFile method of the X509Certificate to add the certificate to the WebRequests client certificates. I belive this method extracts the public key from the certificate If I try and call the GetResponse method, an exception is thrown - The remote server returned an error : (401) Unauthorized.

• eric02 SQLCommand insert not working for dataset with more than one row.

  I am trying to insert data into 2 tables, Order and Order_Item, in a transaction. Everything works fine if I only have 1 row in my objCartDT datatable. If I have only one row, the 2 tables are updated as expected. But if I have more than one row in the objCartDT datatable, something fails, and I can't figure out what (but I suspect it has to do with the params in conjunction with "cmdNewOrder_Items.ExecuteNonQuery();" and the looping I'm trying to do. Maybe not. I will paste the function that is called on button click (to submit the order).
