    - Struct pointer to unmanaged code - exceptions generated I'm now working in manage code. Using Status lStatus = (Status)Marshal.PtrToStructure(pData, typeofStatus)); and out IntPtr But it is still not working. I still have a stackOverflow Exception... I know that it is not the unmanaged function who isn't working because it works perfectly well on my C test program. The last thing that I see that might cause trouble is the strcuture passed as a parameter pMsgInfo which is described as follow in C# : Code Snippet [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)] public struct MSG_INFO { [MarshalAs(UnmanagedType.U4)] public UInt32 comID; [MarshalAs(UnmanagedType.U2)] public UInt16 msgType; public IntPtr pCallerRef; [MarshalAs(UnmanagedType.U4)] public UInt32 sessionId; [MarshalAs(UnmanagedType.U4)] public UInt32 srcIpAddress; [MarshalAs(UnmanagedType.I4)] public int resultCode; [MarshalAs(UnmanagedType.I4)] public int noOfResponses; [MarshalAs(UnmanagedType.U2)] public UInt16 UserStatus; [MarshalAs(UnmanagedType.U4)] public UInt32 ResponseTimeout; [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 15)] public string DestURI; [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 15)] public string SrcURI; } Here is the components of the struct in C : Code Snippet UINT32 ComID UINT16 MsgType void *pCallerRef UINT32 SessionId UINT32 SrcIpAddress int ResultCode int Responses UINT16 UserStatus UINT32 ResponseTimeout char Destination[15] char Src[15] I've tried to pass an IntPtr instead of a ref MSG_INFO, but it doesn't work the way I want telling me about the blittable thing, but I can't really change my manage to have blittable data... Code Snippet IntPtr pTest = Marshal.AllocHGlobal(Marshal.SizeOf(typeof(AppsIPTCom.MSG_INFO))); Marshal.StructureToPtr(typeof(AppsIPTCom.MSG_INFO), pTest, false); Here's the reste of my code which is now managed, if you "see" something that might cause a stack overflow, please advise me if not I'll try another way or contact the entreprise of has done this code. Thank you Code Snippet static extern int MDComAPI_getMsg( [In, Out, MarshalAs(UnmanagedType.SysUInt)] IntPtr queue, [In, Out, MarshalAs(UnmanagedType.Struct)] ref MSG_INFO pMsgInfo, out IntPtr ppData, //instead of char** ppData, [In, Out, MarshalAs(UnmanagedType.U4)] ref UInt32 pDataLength, int timeOut); Code Snippet static public int GetMsg(IntPtr queue, ref MSG_INFO pMsgInfo, out IntPtr ppData, ref UInt32 pDataLength, int timeOut) { int Ret = MDComAPI_getMsg(queue, ref pMsgInfo, out ppData, ref pDataLength, timeOut); return Ret; } Code Snippet while (true) { UInt32 bufLength = Convert.ToUInt32(100); try { IntPtr pData = Marshal.AllocHGlobal(100); // Look until the message queue (recQueue) is empty while (AppsIPTCom.GetMsg(recQueue, ref msgInfo, out pData/*pRecBuf*/, ref bufLength, 0) == 1) { if ( msgInfo.msgType == DATA ) { if (bufLength == Marshal.SizeOf(typeof(Status))) { // A message has been received... Status lStatus = (Status)Marshal.PtrToStructure(pData, typeofStatus)); // CALL THE RICHTEXTBOXSTATUS FROM AN INVOKE FUNCTION MessageBox.Show("State: " + lStatus->State); // } //} Marshal.FreeHGlobal(pData); } catch (Exception e_) { MessageBox.Show(e_.Message, STR_ERROR_TITLE, MessageBoxButtons.OK, MessageBoxIcon.Error); return; } Thread.Sleep(500); } Tag: Visual C# General Creating .EXE?

    - Cursor Class I'm a big fan of RAII as well; but .NET doesn't have deterministic destruction like C++. You've got the Dispose idiom in .NET; but you have to explicitly use it. Forcing a C++ concept into another language that doesn't have the same semantics isn't generally a good idea. If you don't wrap the MyCursor allocation in "using" (or call "Dispose") the MyCursor class is basically useless. "Dispose" isn't intuitive that it should do anything other than free resources Code Block . MyCursor doesn't free resources, it restores state. For example: MyCursor myCursor = new MyCursor(Cursors.WaitCursor) // do something myCursor.Dispose(); (try/finally ignored for brevity) You can't expect someone reading this code to know that Dispose restores the visible cursor. For that matter, it's not obvious that "MyCursor(Cursors.WaitCursor)" sets the visible cursor. Yes, it works; yes, it offers a certain amount of reliability when used with "using"; but I think you could do the same thing with the same performance and be a lot more readable/maintainable..

    - WH_MOUSE_LL in a Windows Service Those are native Windows API calls. The .NET framework version of a message loop is Application.Run() or Form.ShowDialog(). You are in little explored territory here, services and message loops are a poor match. Note that Vista has completely removed the ability for a service to interact with the desktop. Have you considered using a regular app that you start at user login You already know how to keep the form hidden... Tag: Visual C# General Creating .EXE? Visual C#

    - Programmly close screensaver. I agree with you that an application should not mess with stuff outside it's domain but in this case the clients are "my own" computers and the clients wish to have it this way. As a matter of fact I found a very simple way to solve the problem by just change the mouse position. // Oscar Code Block Point p = Cursor .Position; p.X += 50; Cursor .Position = p; p.X -= 50; Cursor .Position = p; Tag: Visual C# General Creating .EXE?

    - Debugging feature... I was debugging a program just a second ago and there was this section at the bottom that showed the values of every single variable in the program at the point at which my program threw an exception. I detatched it from the bottom to look at it side-by-side with the code, and next time I debugged, it wasn't there, and I don't know what it's called or how to get it back...

    - Clearing large arrays from memory Sure, that seems reasonable - I can appreciate that good resource-handling strategies can sometimes appear counter-intuitive. Although a further question occurs to me - could the situation arise where the GC has a large amount of memory waiting to be freed in G0 because the current demands are low, while other processes that aren't subject to GC (i.e. not .NET) are struggling to allocate memory and being slowed as a result In other words is the GC aware of immediate memory demands of other processes, or does the physical/virtual memory mechanism of the OS tend to smooth out the effects in such a situation Thanks.

    - Using SerialPort with USB and removing USB cable while port is open Hi, I am having the problems you have been talking about, but am also seeing problems with CPU usage and memory leaking. If I am running a task manager, and run my program below, when i remove the USB port at the MessageBox (don't hit the 'OK' button)the CPU usage goes to near 100% and stays there and memory usage is in a continual ramp up. Left it running until it hit 500MB at which my 512Mb machine was running quite poorly. When I close the message box, I get the error dialog similar to what you are seeing. I have tried 2 different vendors USB-Serial adapters - with different drivers and the problem as epected exists with both. private static void USB_RemovedError() { System.IO.Ports. SerialPort sp = new System.IO.Ports. SerialPort ( "COM7" ); try { sp.Open(); sp.Write( "Hello cruel removed USB port world!" ); } catch ( UnauthorizedAccessException uae) { MessageBox .Show( "UnauthorizedAccess: " + uae.Message); } catch (System. Exception eee) { MessageBox .Show( "Exception: " + eee.Message); } MessageBox .Show( " Now Remove the USB cable at the PC side." ); } Tag: Visual C# General Creating .EXE? Visual C#

    - Combination console/form application I have an existing console application that I want to extend with an optional GUI front end. I would like for this to all exist in a single executable rather than writing two separate versions (a console app and a windows app). If the user runs the executable normally, I want the application to run in a command window. If the user runs the executable with a specific parameter, say: program.exe -visual I want the program to run at the command line, but open a windows form where it spits out various output (different output than that going to stdout, so I'm not looking for a redirect solution). My first instinct was to have the console application start up the GUI and then update a textbox via a delegate function. Of course, for the GUI to update itself, and for the console app to continue its work, the GUI would need to be in its own thread. What is the best way of going about this Should the console app spawn a thread which then calls Application.Run(...) What then is the best way for the console app to send data over for the GUI to display I'm open to all suggestions. Thanks. Tag: Visual C# General Creating .EXE? Visual C#

Stupid question time. I'm totally new to C# and .NET and I just want to create a .EXE file that does the following. First, there won't be any user interaction. I just need for the executable to FTP a file, parse it, and send an email based on what it finds. I'll also want to schedule the file to be executed with the atrun command. I can figure out how to perform each of those functions but how does one create such a file in VisualStudio Do I just create a Visual C# Windows Application project, and will that generate the .EXE file

Thanks very much.

Re: Visual C# General Creating .EXE?

Mark Dawson

Hi,

in visual studio you can create 2 main kind of applications Windows Applications or Console Application. Sounds like you need a minimal UI, if at all so you can create a Console Application. That will generate an EXE and will display if you want a window like a command prompt. All you need to do in Visual Studio after you create the project is compile the project and it will generate an EXE for you.

Mark.
