Ya I created a handle to the open key and all of that is fine (closed the handle appropriately etc). Its just with the strcpy that I'm having the problems with.
As well, either by passing via reference or returning LPSTR value, I am still receiving the same unhandled exception error. It still crashes when my program is loaded.

I just did a test using your code(with some modifications in bold) except without the reference and it works fine.:
void somefunc()
{
char cBuffer[400];
retrieveLogFileLocation(cBuffer);
}
bool retrieveLogFileLocation(LPSTR value)
{
char lszValue[255];
HKEY hKey = HKEY_LOCAL_MACHINE;
LONG returnStatus;
DWORD dwType = REG_SZ;
DWORD dwSize =255;
bool success = true;
RegQueryValueEx(hKey, "InstallationPath", NULL, &dwType, (LPBYTE)&lszValue, &dwSize);
strcpy(value, lszValue);
return true;
} I set hKey just for testing purposes. It could be a problem with your key.

While it's true that the registry key must be opened prior to use, it's certainly not being modified.

What is the size of the variable that value refers to?
capricious_001 wrote: char[255] lszValue;
What's this?

What does RegQueryValueEx() return?
capricious_001 wrote: strcpy(value, lszValue);
Use strncpy() instead.

How could I show a CString use notepad.exe without saving the string into a txt file?

See
<br />
::ShellExecute(NULL,_T("open"),_T("notepad.exe"),NULL,NULL,SW_SHOWNORMAL);<br />
Sleep(150);<br />
<br />
HWND hNoteWnd=::FindWindow(_T("Notepad"),NULL);<br />
LPCTSTR MY;<br />
MY=_T("Check");<br />
<br />
CWnd* hEditWnd=FindWindowEx(hNoteWnd,NULL,_T("Edit"),NULL);<br />
::SendMessage(hEditWnd->m_hWnd,WM_SETTEXT,0,(LPARAM)MY);<br />
<br />

Use ShellExecuteEx() and these two statements can be avoided.

Hi guys
I get following error when running my program.
Run-Time Check Failure #2 - Stack around the variable 'Temp' was corrupted.
where 'Temp' is a pointer to a class.
Does anyone know what the source of this run time error is ?
regards
Mahdi

Maybe you have some strings (or arrays) around the Temp variable, and you assigned too long values to that strings?

Initialize Temp variable with NULL.. are you using Temp variable without being intialise.. this is common error arises in Visual Studio .net 2003 and above

Can you show your code that has error

how can we apply socket program to send data from parent dialog to child dialog;
sree.
|
|
|
|
|
And why would one do this?
It's easy to pass data from parent dialog to child dialog using GetParent()......
etc.
However you will have to create a socket in your parent dialog, send data on it and then keep on listening to the port that you are binding the socket to, in your child dialog(in your case).
Somethings seem HARD to do, until we know how to do them.

Just create the pointer of the Parent dialog into child dialog and before modeling the child dialog just assign the parent dialog pointer and now you can get the access to parent dialog;'s data from its child dialog.

You can use GetParent() to get the pointer to the parent class in the child dialog and then do whatever you want with those variables.
ex:
CTestDlg* wnd=(CTestDlg*)GetParent ();
wnd->m_edit .SetWindowText ("Anshuman");
where CTestDlg is the parent class and in OnInitDialog of the class associated with the child dialog I have written the above two lines of code. From the second dialog I am setting the text to the edit(m_edit is the control variable) window on the first ie parent dialog

here we r sending the data from child to parent.but what our intension from parent to child .because we must send points from parent.
sree.

I showed you how you can access variables, controls etc from the child dialog that are in the parent dialog. In the same manner you can access functions from the parent dialog in the child dialog. It was not about how you return values from child to parent but it showed how you can do it other way round.
Suppost you are having a function in your parent dialog
CPoint ReturnPoints()
{
return xpoint; //xpoint is a variable in your code of CPoint type
}
You can use this function as
CPoint valueOfPoint=wnd->ReturnPoints();

Here m_pParentDlg is declared as Pointer of the Parent dialog into child dialog.
CChildDlg dlg;<br />
dlg.m_pParentDlg=this;<br />
dlg.DoModel();
use the variables of the Parent dialog into Child Dialog as m_pParentDlg->points
Set the points variable before modeling the Child Dialog
Hope now you understand what i want to suggest..

 I think it is more easy...
wat type of points u need to send???
call the function of child created by u.
here am sending name to child from parent.
I have a function SetName( CString strName ) in child for it.
objChild.SetName( "Sree" );
Keep the name in a varible in Child class and use it.
yours faithfully
