While this does work, it would be much simpler with just:
strcpy(szString, YourString);

Just to be complete:
I think
char* szString = new char[YourString.GetLength()+1];
doesn't need the +1; (a "\0" is already in the CString)

It does need it, cos the GetLength return the length of the string without the terminating \0

hello,
I've some strange problems while debugging, I've one solution with 4 project,2 are exe files, the other 2 are dll.
My problem is I can't see the value of variables while debugging outside the main file.
for example
<br />
case WM_INITDIALOG:<br />
<br />
SetWindowPos(hWnd, NULL, wi.rcWindow.left, wi.rcWindow.bottom, 300, 250, NULL);<br />
ShowWindow(hWnd,SW_NORMAL);<br />
if(hParser == NULL)<br />
{<br />
MessageBox(hwndMain,"LoadLibrary failed on parser.dll", "Error", MB_ICONERROR|MB_OK);<br />
break;<br />
}<br />
if(!AnalizeMMC(hWnd,NULL))<br />
{<br />
MessageBox(hwndMain,"Unable to process multi-media content file", "Error", MB_ICONERROR|MB_OK);<br />
break;<br />
}<br />
when I step into AnalizeMMC, that's defined into another .cpp file
<br />
bool AnalizeMMC(HWND hWndMMC,tag *ind)<br />
{<br />
char temp[30]={0};<br />
WIN32_FIND_DATA *wfd = new WIN32_FIND_DATA();<br />
HANDLE hFirstFile=INVALID_HANDLE_VALUE;<br />
HWND hList=NULL;<br />
FILE *fd=NULL;<br />
char test[50]={0};<br />
hList=GetDlgItem(hWndMMC,IDC_LIST1);<br />
hFirstFile=FindFirstFile("*.mmc",wfd);<br />
if (hFirstFile == INVALID_HANDLE_VALUE) return false;<br />
.....<br />
I can't see the value of temp,wfd,hFirstFile and so on...
I receive
wfd CXX0017: Error: symbol "wfd" not found
.......why this happens???, how to fix it?????
the same happens if I refer to content of another project.
Thanks
Paolo

Have you tried just debugging the DLL in question?
That is set the DLL to active project / startup project then when prompted for the executable choise the appropriate executable that uses the DLL.

Change

I have placed a webcontrol on CFormView in a SDI application.I have assigned it a member variable m_webbrowser.
Also i have got a dilogbox derived from Cdialog in my application.
I need to access this m_webbrowser from my dialogbox.
Please let me know how to do it
|
|
|
|
|
When the dialog object is instantiated, pass it a pointer to the m_webbrowser variable.

Since I've included a MFC-based dialog in the DLL I am developping, icons that were displayed in a toolbar have disappeared. These icons are managed with Windows API :
tbab.hInst = MaDLL::hInstance ;
tbab.nID = IDB_ICONE_OBM ; // icon id in ressources
val = SendMessage (hwndToolbar, TB_ADDBITMAP, 1, (LPARAM)&tbab) ;
This code worked fine until I have included my dialog box and MFC lib
|
|
|
|
|
It could be that your IDB_ICONE_OBM is conflicting with other resource ID in resource.h. Remove the duplication if there is.
(You can also use the ResOrg , a small utility written by one of the CPians to resolve the ID conflict.)

Hi,
currently I’m migrating a VB program to VC++ 6.0. Some functions in the VB program are called by the function Keys (F2-F12). This function should be in the new program too. My problem is, that I don’t know how to do this. in VB its just the "OnKeykDown". Is there an easy possibility to route the messages from the control which has the focus to the Dialog???
Thx
btw: Sorry for bad english
|
|
|
|

Are you using the MFC ? If yes, go to the resources tab and there you have the accelerator resource. For each key you want to be used, create a new unique message id (if required) and then add the accelerator with it's associated Id.
Then with ClassWizzard, add a function for each message ID.
Hope this helps

This doesn't work if you have a Dialog App, but it works in SDI with FormView. So I do it so.
Thanks 4 help

In the dialog's constructor, you'll need to call LoadAccelerators(). Then you'll need to override the PreTranslateMessage() method like:
BOOL CMyDlg::PreTranslateMessage( LPMSG pMsg )
{
if (NULL != m_hAccelTable)
{
if (::TranslateAccelerator(m_hWnd, m_hAccelTable, pMsg))
return(TRUE);
}
return CDialog::PreTranslateMessage(pMsg);
}

Thats it! Now it works even in a Dialog. Thanks!

Hi I am controlling an electrical circuit using the computer through the computer ports. I am trying to capture a fast changing analog signal using sampling. So I am just enquiring about the maximum frequency that we could set the timer to using the following function:
SetTimer(1, 2000, 0);
I actually want the timer to interrupt every ten micro seconds (10uS). Is it possible with this type of timers. If not, can anyone guide me to a timer that is capable of doing so.
Thanx in advance
|

Timers are set in milliseconds and therefore do not have the resolution you require.
I suggest that you use another thread to do this work. You could then use the high-resolution performance counters QueryPerformanceCounter() and QueryPerformanceFrequency() to monitor the time.

Are these actually counters or are they functions that retrieve the frequeny and index of a counter?
Check out this link plz.

I was suggesting that you uses the performance counter functions in order to write your own high-resolution timer.

I created a simple user control in C# which has a button in it.
//DemoControl.cs
namespace DemoControl
{
public class UserControl1 : System.Windows.Forms.UserControl
{
private System.Windows.Forms.Button button1;
///
/// Required designer variable.
///
private System.ComponentModel.Container components = null;
public UserControl1()
{
// This call is required by the Windows.Forms Form Designer.
InitializeComponent();
// TODO: Add any initialization after the InitComponent call
}
///
/// Clean up any resources being used.
///
protected override void Dispose( bool disposing )
{
if( disposing )
{
if( components != null )
components.Dispose();
}
base.Dispose( disposing );
}
#region Component Designer generated code
///
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
///
private void InitializeComponent()
{
this.button1 = new System.Windows.Forms.Button();
this.SuspendLayout();
//
// button1
//
this.button1.Location = new System.Drawing.Point(16, 16);
this.button1.Name = "button1";
this.button1.Size = new System.Drawing.Size(88, 32);
this.button1.TabIndex = 0;
this.button1.Text = "button1";
this.button1.Click += new System.EventHandler(this.button1_Click);
//
// UserControl1
//
this.Controls.Add(this.button1);
this.Name = "UserControl1";
this.Size = new System.Drawing.Size(608, 248);
this.MouseMove += new System.Windows.Forms.MouseEventHandler(this.UserControl1_MouseMove);
this.ResumeLayout(false);
}
#endregion
}
}
The i created an MFC ActiveX control to host the C# control
//HostCtrol.cpp
int CMfcHostCtrl::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (COleControl::OnCreate(lpCreateStruct) == -1)
return -1;
AfxEnableControlContainer();
DemoControl::UserControl1* pcal = new DemoControl::UserControl1();
CComPtr<iunknown> spunkControl;
spunkControl.Attach((IUnknown*)System::Runtime::InteropServices::Marshal::GetIUnknownForObject(pcal).ToPointer());
CRect rectPlaceHolder;
GetClientRect( &rectPlaceHolder );
m_ctrl.Create(spunkControl, WS_VISIBLE | WS_TABSTOP, rectPlaceHolder, this, 0);
return 0;
}
where m_ctrl is CWinFormsControlWnd class which i downloaded from the MSDN Magazine at http://msdn.microsoft.com/msdnmag/issues/03/03/WindowsForms/default.aspx
It works great, but the hosting application stuck when i press the button.
Does anyone knwos whats wrong?
Amir.

I have been trying to make a library to convert VB code to C++. Incase you feel you need something like this please visit http://ezbasic.sf.net/
I will try and post an article about the library on CodeProject if I get enough people who are interested in the project.
Regards,
Vivek Jishtu

Eeeeeeeeeeeek.... 
Err, what are the advantages of doing this ????? 
|
|
|
|

Well quite a few months of effort has gone into the project. And to get something like this as a comment is not the best way of starting things.
