error C2039: 'SetWindowTextA' : is not a member of 'ATL::CStringT<BaseType,StringTrai

[Steph86]

I think pretty much all the errors you got come from a typo from my side. You need to put a coma rather than a semicolon int the initialisation list, before "m_pDialog"

I put the coma in and now i have 2 errors:

error C2614: 'MySdk2Client' : illegal member initialization: 'm_pDialog' is not a base or member
error C2512: 'MySdk2Client' : no appropriate default constructor available

Hi erik, thanks for your input, would it be possible for you to show me how to do your method 2 with the code i have posted above.

I am really new to programming and it is a lot easier if i see it implemented into my code and then I am able to understand what is going on.

Thanks again for all your help
Regards
Steph

In my message with the typo, there was a first piece of code. It is the declaration of m_pDialog that you need to add to your class. Then it will know about it.

I did put that in, thats why I showed you the header file:

Here it is again have i put it in the correct place:

Header file:

#pragma once
#include "afxwin.h"


// CConnectDlg dialog

class CConnectDlg : public CDialog
{
	DECLARE_DYNAMIC(CConnectDlg)

public:
	CConnectDlg(CWnd* pParent = NULL);// standard constructor
	virtual ~CConnectDlg();
	CConnectDlg* m_pDialog;

// Dialog Data
	enum { IDD = IDD_CONNECT };

protected:
	virtual void DoDataExchange(CDataExchange* pDX);    // DDX/DDV support

	DECLARE_MESSAGE_MAP()
public:
	
	
	CString m_NOFTR;
	CString m_NOFR;
	DWORD m_Eipaddress;
	DWORD m_Cipaddress;
	afx_msg void OnBnClickedOk();
	CStatic m_Status;
};

Hi erik, thanks for your input, would it be possible for you to show me how to do your method 2 with the code i have posted above.

It looks like you know about it, you are doing it with CStatic with your m_Status. Just do the exact same, except with CEdit, to do an edit box. Remove the CString, it is best to only do one type of exchange at a time (although you CAN to both if you want). Just do a m_MyControl.GetWindowText(sString), to fill in the string when you want to read it.

Hi Erik, I have already tried what you suggested but it does not work, I just tried it again to make sure and the same thing happens.

I created a new control cedit called m_Number, and put the code as follows:

void MySdk2Client::SdkDataHasArrived(sFrameOfData* data)
{
	WriteFrame(data);

	// Stop accepting frames of data once we reach the number set by the user on the command line
	if (++m_frameCount == m_maxFrames)
	{
		m_acceptData = false;
	}

	if (m_frameCount % 10 == 0)
	{
	
		

		m_Number.SetWindowText("%d\r", m_frameCount);

}

But i get the following errors just like before, this is what Elrond is trying to help me overcome.

error C2065: 'm_Number' : undeclared identifier
error C2228: left of '.GetWindowTextA' must have class/struct/union

The reason i think its happening is because the m_Number is in:

void CConnectDlg::OnBnClickedOk()

and its trying to read it in:

void MySdk2Client::SdkDataHasArrived(sFrameOfData* data)

[ZuK]

You have put the declaration

CConnectDlg* m_pDialog;

into the wrong class.
It's MySdk2Client that needs to know about the dialog to be able to update the dialogs's data.

1. Did you put the "CEdit m_Number;" into your class declaration?
2. Did you add "DDX_Control(pDX, IDC_NUMBER, m_Number);" into the exchange?

Once you do that, there is no reason for them not to exist.

Also, make sure they are in the same class as ZuK suggests.

Thanks Zuk, I just put that in like this:

class MySdk2Client : public ISdkDataListener
{
	
public:
	CConnectDlg* m_pDialog;
	
	// Constructor
	MySdk2Client(CConnectDlg* pDialog) : m_acceptData(false) , m_pDialog(pDialog)
	{
		for (int i = 0; i < DATA_TYPE_COUNT; i++) 
		{
			m_dataFiles[i] = NULL;
		}
	}

	// Destructor, must close the data files
	~MySdk2Client() 
	{
		for (int i = 0; i < DATA_TYPE_COUNT; i++)
		{
			if (m_dataFiles[i]) fclose(m_dataFiles[i]);
		}
	}

	// Required method to implement the ISdkDataListener interface.
	// Once we register ourselves with an EvartSdk2Interface object,
	// this method will be called whenever a frame of data arrives from
	// EVaRT.
	virtual void SdkDataHasArrived(sFrameOfData* data);

	// Required method to implement the ISdkDataListener interface.
	// This should return true if frames of data are currently being
	// accepted, and false if you do not want to receive frames of data.
	virtual bool AcceptingSdkData() const { return m_acceptData; } 

	// Connect to the EVaRT SDK2 running on "serverIP" using the NIC in
	// our client machine with IP address "clientIP"; maxFrames is the number
	// of frames to write to the data file before exiting.
	bool Connect(const char* serverIP, const char* clientIP, int maxFrames);

	// Have we received all the frames required
	bool IsFinished() const		{ return m_frameCount >= m_maxFrames; }
	
	// Unregister ourselves from the EvartSdk2Interface object
	void Disconnect()
	{
		m_sdk.SetDataListener(NULL);
		m_sdk.Uninitialize();
	}

	// Create a file for the given data type
	bool CreateDataFile(int dataType, const char* filename)
	{
		bool rc = false;

		if (dataType >= 0 && dataType < DATA_TYPE_COUNT)
		{
			m_dataFiles[dataType] = fopen(filename, "w");
			rc = (m_dataFiles[dataType] != NULL);
		}

		return rc;
	}

private:
	
	bool m_acceptData;
	int m_frameCount;
	int m_maxFrames;
	FILE* m_dataFiles[DATA_TYPE_COUNT];
	EvartSdk2Interface m_sdk;

	void WriteFileHeader(int dataType, sBodyDefs* bodyDefs);
	void WriteFrame(sFrameOfData* data);

	void WriteIdentifiedHeader(FILE* fp, sBodyDefs* bodyDefs);
	void WriteUnidentifiedHeader(FILE* fp, sBodyDefs* bodyDefs);
	void WriteSegmentHeader(FILE* fp, sBodyDefs* bodyDefs);
	void WriteDofHeader(FILE* fp, sBodyDefs* bodyDefs);
	void WriteAnalogHeader(FILE* fp, sBodyDefs* bodyDefs);
	void WriteForceHeader(FILE* fp, sBodyDefs* bodyDefs);

	void WriteIdentifiedFrame(FILE* fp, sFrameOfData* data);
	void WriteUnidentifiedFrame(FILE* fp, sFrameOfData* data);
	void WriteSegmentFrame(FILE* fp, sFrameOfData* data);
	void WriteDofFrame(FILE* fp, sFrameOfData* data);
	void WriteAnalogFrame(FILE* fp, sFrameOfData* data);
	void WriteForceFrame(FILE* fp, sFrameOfData* data);
};

now i only have one error left:

error C2512: 'MySdk2Client' : no appropriate default constructor available

[ZuK]

now i only have one error left

Looks like MySdk2Client needs to have a default constructor. If that is so the you will have to add a SetDialog() member

something like

class MySdk2Client : public ISdkDataListener
{
	
public:
	CConnectDlg* m_pDialog;
	
	// Constructor
	MySdk2Client(CConnectDlg* pDialog = 0) : m_acceptData(false) , m_pDialog(pDialog)
	{
		for (int i = 0; i < DATA_TYPE_COUNT; i++) 
		{
			m_dataFiles[i] = NULL;
		}
	}
        void SetDialog( CConnectDlg* pDialog ) { m_pDialog = pDialog; } 

and add a call to SetDialog() after construction of the MySdk2Client.

Hi zuk, I done exactly as you said:

class MySdk2Client : public ISdkDataListener
{
	
public:
	CConnectDlg* m_pDialog;
	
	// Constructor
	MySdk2Client(CConnectDlg* pDialog = 0) : m_acceptData(false) , m_pDialog(pDialog)
	{
		for (int i = 0; i < DATA_TYPE_COUNT; i++) 
		{
			m_dataFiles[i] = NULL;
		}
	}
void SetDialog( CConnectDlg* pDialog ) { m_pDialog = pDialog; }
	
// Destructor, must close the data files
	~MySdk2Client() 
	{
		for (int i = 0; i < DATA_TYPE_COUNT; i++)
		{
			if (m_dataFiles[i]) fclose(m_dataFiles[i]);
		}
	}

and when i compile i still get the same errors:
error C2065: 'm_NOFR' : undeclared identifier
error C2228: left of '.SetWindowTextA' must have class/struct/union

It still can't find m_NOFR in:

void MySdk2Client::SdkDataHasArrived(sFrameOfData* data)
{
	WriteFrame(data);

	// Stop accepting frames of data once we reach the number set by the user on the command line
	if (++m_frameCount == m_maxFrames)
	{
		m_acceptData = false;
	}

	if (m_frameCount % 10 == 0)
	{
	
		m_NOFR.SetWindowText("%d\r", m_frameCount);

	}
}

[ZuK]

m_NOFR is not a member of MySdk2Client.
It would have to be

m_pDialog->m_NOFR.SetWindowText("%d\r", m_frameCount);

Guess this way you will get rid of the compile errors. Now you will have to struggle with runtime errors.

Steph86, in my opinion you would be further ahead by putting this project aside for a day or two and spend the time working on an MFC tutorial.

Probably the best tutorial to start out with is the 'Scribble' tutorial.

It walks you through the steps to build a simple drawing app, but more importantly explains the MFC hows and whys along the way.

Based on your repeated questions covering the basics, working through the tutorial would give you the foundation necessary to get on with your real program.

Read the instructions for getting the scribble sample files:

Visual Studio 2008
http://msdn.microsoft.com/en-us/library/f35t8fts.aspx

Visual Studio 6.0
http://msdn.microsoft.com/en-us/libr...27(VS.60).aspx

Working through this tutorial is truly worth it.

Thanks for your time zuk,

now i get a different error:
