You could send the message to the mainframe. That should do it for you.

GetLongPathName prob under XP

Hi there,
I've got a program where I read the registry to get the path of an application - on XP.
Once I get that path as it is a dos formatted path I called the GetLongPathName(A) function to convert it to its long name value and I got the following error from GetLastError function:
"prescribed file doesn't exist"

In fact the folder exist but apparently XP doesn't recognize it's DOS name as a valid Windows name (?).
I scanned the "App Paths" registry and noticed that most recent application did have their path with long name form instead of the old fashioned DOS one.

So I am really confused my code is working fine on W98 but not on XP. How could I bypass the GetLongPathName function is there any substitute to convert a valid DOS name to its long name counterpart ?
Thanks,

Yarp

I use GetFullPathName() for this. Give it a try. From memory it doesn't check the disk and therefore doesn't complain if the file doesn't exist.

You might also want to look at AfxFullPath(). If you still have a problem let me know.

Thank you for your reply.

I Couldn't get GetFullPathName work properly too.

In fact I have a dual boot PC (a W2K boot and a XP one) and the application path I'm looking for was installed under XP on c:\program files (c: is the W2K drive). XP itself is located on d:.
So I get the following DOS name from the registry c:\progr~2\Poser\ and I would like the function to return c:\program files\Poser\.

I tried to type c:\progr~2 under DOS and Windows failed to go to the proper folder, but if I type d:\progr~1 it works fine. So I think this is a Windows bug. XP is unable to translate the DOS name from the other drive - because it is the W2K one ? The mistery remains.

Well, few people have dual boots like mine. If it works on another machine I'll just give up.

Refreshing a dialog

This is probably a stupid question but is there any way to refresh a dialog so that all of the data and stuff that is in the dialog is destroyed and then recreated? Any help appreciated.

Hi all,
When I use IDiskQuotaUser->SetQuotaLimit() and ->SetQuotaThreadshold()there are always pop up an error dialog: like this:
//////////////////////////
Dubug Error
Program:**
Modlue:
File:i386\chkesp.c
Line 42
The value of ESP was not properly saved across a function call. This is usually a result of calling a function declared with one calling convention with a function pointer declared with a different calling convention.

Why?????????????????????????????????????

And How to resove this problem?

I tried to use static dll to build the project but failed for LNK2005 error.
also can not resolve the problem.

Thanks for help.

chkesp errors usually have their origins in passing around malicious pointers and/or wrong parameter sizes and counts. In this case it could be the LONGLONG value that's used in those calls. Happened to me once. OMG | :OMG:

T2W

ns19-Sep-02 9:29

19-Sep-02 9:29

In code that I have, theres a T2W. MSDN and the web are not helpful.

 char* strFile = new char[strFile0.GetLength() +1];

strcpy(strFile, strFile0);

_bstr_t b_strFile = T2W(strFile);

What exactly does T2W do?

Thanks,
ns

Re: T2W

Joaquín M López Muñoz19-Sep-02 9:40

T2W converts from TCHAR strings to Unicode strings. Next obvious question is, what are TCHARs? Well, TCHAR is a macro resolving either to char or wchar_t (Unicode character), depending on whether your app is being build in ANSI or Unicode mode. If in Unicode mode, T2W converts from Unicode to Unicode, i.e, it does nothing, but this apparent futility have some sense if you consider that this way the same source code can compile fine in either mode.
In your particular case, your source string is ANSI (char *), which has the following implications:

This will only work in ANSI mode (in Unimode, T2W will accept only Unimode strings).
Taking into account the former, you could have used A2W (ANSI to Unicode) instead

So, I'd label this as a small flaw in the code. You'de be better off using TCHAR * as the type of strFile if pursuing Unicode compatibility.

Re: T2W

ns19-Sep-02 9:59

19-Sep-02 9:59

I dont know how relevant this is, but this all started because I had to pass a CString (coming from GetWindowText) or char* into a VB com dll which had a parameter of type String. T2W fixes that. Should I replace it with A2W. I'm asking because I dont know about setting the mode in VC. I didnt even know I had a choice! Where in the IDE do I set the mode? Also whats the purpose of these two different modes - is it like one runs on Unix and one on windows or something? From your post the default mode my app is being built in must be ANSI. So can you please let me know where the mode setting is (I looked in some obvious places), and why a mode is chosen. Does A2W mean it will work in both modes?

Thanks,
ns

Re: T2W

Well, writing code that compiles in both modes is a tedious task (specially when you didn't planned for it before) and IMHO it is not worth the effort if you don't really need it (which seems your case). If you renounce to compile in Unicode mode, then A2W and T2W are the same, but at least with A2W you are making it splicit that the code is intended for ANSI mode only.
To build your app in Unicode mode, go the project settings and define preprocessor macros UNICODE and _UNICODE. Although you might be able to succesfully build your project please be aware that Windows 9x OSs are not Unicode compliant, so the app won't just run (in Windows NT/2k/XP it should).
The difference between ANSI and Unicode modes is that the OS APIs you call are different in either mode, accepting char * or wchar_t * strings (for APIs not dealing with text, as for instance GetMessage there's no difference). Unicode is intended for apps in exotic languages, having often more characters than a single char can accommodate.

Apart from this, I think you can simplify your code a little:

USES_CONVERSION;
LPCOLESTR lpcostr=A2COLE((LPCSTR)fileString);
//call the VB DLL using lpcostr

Dbl Click in control - DateTimePicker

Hi.

I want to recognize a double click (right mouse button) in a DateTimePicker control, but don't know how to or aware of scenarios that might cause a problem with this.

What I have is grid of edit-able controls (CEdit, CDateTimePicker, CComboBox) and for a Date Time Picker, I want a double-click to capture the current time.

This is to help data entry by the user.

Any help/suggestions?

Thanks.

OnInitDialog question

ns19-Sep-02 9:02

19-Sep-02 9:02

I have a CDialog derived class I want to use in two places, which differe in functionality. If I set a flag from the spawning

view class (which does a DoModal()), is it allowed to set a flag that will make OnInitDialog behave differently?

BOOL abc = TRUE;

myDlg.SetFlag(  abc) //which sets a member of the CDialog class.

myDlg.DoModal();

and in the CDialog class, :

::OnInitDialog()
{
if (m_flag)
    {

        dosomething;
     }
else
    {
      dosomethingelse;
    }

Is this allowed? I cant really write two different OnInitDialogs, right? So in order to reuse it I am thinking of my flag idea.
Suggestions?

Thanks,
ns

Yes, you've got it right. Personally, I would make an enumeration variable in the dialog class and use that as the flag. That way, you can switch() on the flag and support future enhancements when you want more than two different behaviors. Just as soon as you've written all the code for two modes you'll find that you now want to have three Smile | :)

The additional effort involved is very little.

<code>
class CMyDlg : public CDialog
{
public:
    typedef enum
    {
        Mode1,
        Mode2,
        Mode3
    } MyDlgModes;
 
private:
    MyDlgModes m_Mode;
 
public:
    SetDlgMode( MyDlgModes Mode )
    {
        m_Mode = Mode;
    }
};
 
BOOL CMyDlg::OnInitDialog()
{
   switch( m_Mode )
   {
   case Mode1:
       ... do stuff
   case Mode2:
       ... etc
   
   }
}
 
MyFunc()
{
    CMyDlg dlg;
    dlg.SetDlgMode( CMyDlg::MyDlgModes::Mode1 );
    dlg.DoModal();    
}

Once again, a million thanks for your patiently detailed resolution. It helps tremendously! I thought I'd have to define the enum globally (can this even be done? like an extern enum)so using the enum declared in CMyDlg is pretty tricky! Appreciate your responses very much indeed!
