I am confused! what is your primary aim in this task?

I'll try it graphically:
|---------------------------- - -
| Tab 1 | Tab 2 | Tab 3 |
|---------------------------- - -
|
| static text: dynamic text
|
| |-----------| |-----------|
| | . . . . . . .| | . . . . . . |
| | dialog2 | | dialog2 |
The static text and the dynamic text are there everytime, that's why they are in dialog1. Depending on the settings below these texts there can be one to three columns which are identical except they have different values. So I try to dynamically add this dialog as often as it is needed.
Was this comprehensible enough?
|
|
|
|
|
in this case i would create all controls of the dialog2 in dialog1 with different IDs and use showwinow() to show the needed controls.
Is that too easy?

Well, that's how I would have done it normally as well but I thought there must be an easier way. I'm aware that in the time it took me searching for another solution I could have done all the writing as well but it would be easier to administrate the way I imagined it because I could easily add all the controls which are needed at once.
Mh, but it looks like I must go the normal way.
Thank you very much for your help.

They are far easier to use than a tabbed control.

Do these "invisible child dialogs" have the style "Visible" set to "True" in dialog editor?

Hi Code-o-mat,
I tried each possible combination for the visibility of the two dialogs, but no success.
|
|
|
|

Are you sure your child dialog got created (did for example its OnInitDialog run)? Did you try explicitly calling ShowWindow(SW_SHOW) on it after it was created? How did you embed it into your other child dialog? Is it maybe a drawing problem, try setting "Clip children" to TRUE on the dialog that contains the other child that seems invisible.

The OnInitDialog was called properly.
CReportStack softwareStack;
softwareStack.Create(IDD_REPORT_STACK, this);
softwareStack.SetGroupTitle(_T("Software Stack"));
CRect rectChild;
softwareStack.GetWindowRect(&rectChild);
softwareStack.MoveWindow(12,66,
rectChild.right-rectChild.left,rectChild.bottom-rectChild.top);
softwareStack.ShowWindow(SW_SHOW);
This is the code where I create the dialog. Clip children also didn't have any effect.

Did you check what is the last error using CeGetLastError What is the error when you use CeGetLastError?
You need to google first, if you have "It's urgent please" mentioned in your question.

When i m using CeRapiGetError() than its return "The Device is not Ready."
and when i m using CeGetLastError() than its return "The Operation was completed successfully"

Hi all,
I am getting a value from a Edit box using this code
CString str1;
GetDlgItemText(IDC_LEFT,str1);
I want to convert this value to an integer, i know i can use atoi function to convert it but my problem is when the value in str is equivalent to 4312576705 atoi returns a value 2147483647.
i tried to convert it using long function but the result remains same.
now what should i do??
Can anybody help me in this.
Thanks in advance

Why trying for just atoi?
integer( -2147483648 to +2147483647) can adjust a limit of at a max.
so use _int64( -9223372036854775808 to +9223372036854775808 )
__int64 nData = _atoi64( const char* );
Величие не Бога может быть недооценена.

Hi All,
Can anybody tell me how to retreive hard disk interface type without using WMI classes in MFC.WMI classes is not working with all PCs.
Thanks

Hi Abinash,
The MFC classes[^] are a very small subset of the Microsoft Windows API. The answer to your question is that MFC does not have any methods of determining a drive volume bus type.
But you can use the IOCTL_STORAGE_QUERY_PROPERTY[^] control code to obtain the STORAGE_BUS_TYPE[^]. Here is an example:
#include <winioctl.h>
#define IOCTL_STORAGE_QUERY_PROPERTY CTL_CODE(IOCTL_STORAGE_BASE, 0x0500, METHOD_BUFFERED, FILE_ANY_ACCESS)
STORAGE_BUS_TYPE GetDriveBusType(DWORD dwDrive)
{
STORAGE_BUS_TYPE sbt = BusTypeUnknown;
HANDLE hDrive;
TCHAR szDrive[MAX_PATH];
_stprintf(szDrive,_T("\\\\.\\PhysicalDrive%d"), dwDrive);
hDrive = CreateFile(szDrive,GENERIC_READ | GENERIC_WRITE,FILE_SHARE_DELETE | FILE_SHARE_READ | FILE_SHARE_WRITE,NULL, OPEN_EXISTING, 0, NULL);
if(INVALID_HANDLE_VALUE != hDrive)
{
DWORD dwSizeBytes;
STORAGE_PROPERTY_QUERY q;
ZeroMemory(&q,sizeof(STORAGE_PROPERTY_QUERY));
PBYTE pBuf = (PBYTE)HeapAlloc(GetProcessHeap(),HEAP_ZERO_MEMORY,sizeof(STORAGE_DESCRIPTOR_HEADER));
if(NULL != pBuf)
{
if(TRUE == DeviceIoControl(hDrive,IOCTL_STORAGE_QUERY_PROPERTY,&q,sizeof(STORAGE_PROPERTY_QUERY),pBuf,sizeof(STORAGE_DESCRIPTOR_HEADER),&dwSizeBytes, NULL))
{
STORAGE_DESCRIPTOR_HEADER *pHeader = (STORAGE_DESCRIPTOR_HEADER *)pBuf;
dwSizeBytes = pHeader->Size;
pBuf = (PBYTE)HeapReAlloc(GetProcessHeap(),HEAP_ZERO_MEMORY,pBuf,dwSizeBytes);
if(NULL != pBuf)
{
if(TRUE == DeviceIoControl(hDrive,IOCTL_STORAGE_QUERY_PROPERTY,&q,sizeof(STORAGE_PROPERTY_QUERY),pBuf,dwSizeBytes,&dwSizeBytes, NULL))
{
STORAGE_DEVICE_DESCRIPTOR * pDesc = (STORAGE_DEVICE_DESCRIPTOR *)pBuf;
sbt = pDesc->BusType;
}
}
}
HeapFree(GetProcessHeap(), 0, (LPVOID)pBuf);
}
}
return sbt;
}
Best Wishes,

Could you post the error/problem that you are getting/facing while trying to establish the connection?

The following is the error message I am receiving:
Error number: 80040e4d Login failed for user 'mcertini'.
Error
Code = 80040e4d
Code meaning = I
Source = Microsoft OLE DB Provider for SQL Server

This error message is self-explanatory. Check whether your DSN is setup correctly. Any incorrect DSN(UserID/Pwd) will lead to this error.In addition Pl check if you have right level of access to the database.

Hi everybody,
I have a class called STSource ("ST" is my system prefix) and it represent a program source. i have too, more two classes called STCobol and STHtml. STSource need to execute a function that separate informations using a very specific way that have a same name inside STCobol and STHtml. I don´t like to use conditions sintaxes to check file extension and to decide which object will be instanciated (For me oCobol ou oHtml). How can i instanciated a pointer or something to this.
I need
STSource oSource
if cobol
oLanguage = STCobol
else
if HTML
oLanguage = STHtml
oLanguage.DoSomething()
and not
STSource oSource
if cobol
STCobol oCobol
else
if HTML
STHtml oHtml
if cobol
oCobol.DoSomething()
else
if HTML
oHtml.DoSomething()
Thanks for read my questions
Sorry by poor english, i´m Brazilian
|
|
|
|
|
Have STCobol and STHtml be derived classes from a base class with exactly one pure virtual function named "DoSomething()". Then you can declare oLanguage as type "baseclass" and oLanguage.DoSomething() or (oLanguage->DoSomething() depending on the declaration) will invoke the proper function.
|
|
|
|
|
Humm
If i understood the code will be like this
class STSource
{
public:
virtual void DoSomething()=0; //pure virtual Function Definition
};
class STCobol:public STSource
{
public:
void DoSomething()
{
cout<<"Hi...";
}
};
class STHtml:public STSource
{
public:
void DoSomething()
{
cout<<"Bye...";
}
};
class AnyClass1:
{
STSource* pArray[2];
STCobol oCobol;
STHtml oHtml;
pArray[0]=&oCobol;
pArray[1]=&oHtml;
if cobol
pAarray[0]->DoSomething();
else
if html
pArray[1]->DoSomething();
}
class AnyClass2:
{
STSource* pSource;
if cobol {
STCobol oCobol;
pSource=&oCobol;
}
else
if html {
STHtml oHtml;
pSource=&oHtml;
}
}
pLanguage->DoSomething();
One more question: When i instanciated a STCobol or STHtml, STSource wiil be instanciated automactly
are the above things correct or am i keeping crazy ?
|
|
|
|
|
as i see have done it fine. 
You can do things better like:
if cobol
pAarray[0]->DoSomething();
else
if html
pArray[1]->DoSomething();
}
if the STSource has a function GetClassType() with enums. Or -> CObject and IsKindOf()
