• Visual C++ C# and C++/CLI sharing objects

  Hi guys, I really need some help on this as i'm going slowly insane. What I have is a windows service written in C++/CLI exposing an object with TCP remoting. The remoted object loads a bunch of other objects from a database into a List<> and keeps them in memory for the lifetime of the service. I have another project which is a C# Winforms application which accesses the service using TCP remoting and wants to get access to an object in the list. However, when my C# project gets the object it seems to get a copy of it rather than a reference to it. All the parameters look the same but if I attempt to update it, the C++/CLI "copy" of it doesn't change. I have an event in the object which fires when a property of ...Show All

• .NET Development DataTable Stripping time from DateTime

  Hi all, I have a problem that I can't figure out again and need some help. I import data into a DataTable and I need a tool to remove the time (ie set all to midnight) from the dates in the DataTable to help with grouping after it has been populated. Inside a loop I do this DateTime dtmBuffer = DateTime .Parse(dtbDataGrid.Rows[intLoopY].ItemArray[intLoopX].ToString()); and then I set the DataTable to just the date part dtbDataGrid.Rows[intLoopY].ItemArray[intLoopX] = dtmBuffer.Date; but the new value doesn't seem to be put into the DataTable - the time portion remains at whatever it was before! Can anyone help with any ideas Justine Hi Ilya, Thanks very much for your help - please understand that I was ...Show All

• Visual C# Detect registry changes?

  Is there a way to detect registry changes, using a FileSystemWatcher or other Say a DWORD value changes. How can I show an alert that a registry change occured Thanks, You have to use WMI Events to accomplish that.

• Windows Forms How to Create a Download Update Form?

  Hello, I want to know how to use the System.Net.WebClient in my application. Here is the part of the code: System.Net.WebClient client = new System.Net.WebClient(); client.DownloadFile("http://updates.com/index.xml","c:\\update.xml"); That would download the file "index.xml" and save it in the local computer in drive C under a new name "update.xml".

• Microsoft ISV Community Center Forums passing data in multiple rows in a recordset

  I have a recordset that consit of 5 rows 6 columns. each column has a name. i would like to retrieve the second row in the recordset. I can read the first row, but I am lost as to read the second row in the recordset... help!! hi, there are a couple of Move methods that let you navigate the rows of a recordset, MoveFirst, MoveNext, MovePrevious, MoveLast and just Move. You need to be wary though as moving back and forward through a recordset using these methods will depend what kind of cursor the recordset was opened with, for example you can't call MoveFirst or MovePrevious if your recordset is using a forward only cursor. ...Show All

• .NET Development FTP Error: Index (zero based) must be greater than or equal to zero and less than the size of the argument list.

  Hi, I am using a FTP client in my application. This FTP client is a freeware for .NET version1.1. It works fine for all files except two files. But these two files are required to FTP to a mainframe machine. I am able to FTP these two files in command prompt but getting error if I am trying to FTP through my c# application. These two files are giving two different errors mentioned below: 1. Index (zero based) must be greater than or equal to zero and less than the size of the argument list. 2.

• Visual Basic In the registery?

  I have written a program that requires a password to be created when it is first run, this is then encrypted and stored on the computer C:/Test.txt . the next time the program is run you enter your password, which is encrypted and compared against the encrypted password on file, and if they match you can use the program. I don't think storing the encrypted password as C:/Test.txt is a good thing, so where is the best place to hide it away, and how is it done Any help, advice or interesting articles will be welcome. Thanks NuyN, But to get the file I just use If File.Exists(Passtxt) Then Passtest = True btnPassCreate.Text = "Enter Password" if it doesn't exist then you create a ...Show All

• Visual C# Run application from WindowsService

  I have a windows service that needs to start a windows application at a certain time, but when it runs the application, I can't see it, but I can see it in the taskmanager. Any ideas why could be because its running under your account but in a seperate session. You could see what happens if you try to tell it to interact with the desktop (again from the same place you changed the user account to use) however I would advise against this as its bad practice. you should instead create a winform app that sits in the background which does this instead :-) ...Show All
