hi,
if i have an application, using windows explorer style(consist of left pane and right pane), i want to create a button in the toolbar that delete a selected/highlighted item in either left pane or right pane(can't delete both at the same time).. can this be done? or should i just use 2 buttons instead(one button for deleting items in leftpane and another one for deleting items in right pane).. thx in advance!

You only need one button (think about the copy/cut/paste button in windows explorer, they may be used in both left and right panes).
I do not know much about MDI (since I've developped only few such app till now), but with GetActiveView, you should be able to grab the view whith the item currently selected when hitting your remove button.

Is there a way to create a wizard like the installation wizard that you see for commercial programs?
|
|
|
|
|
Yep. Throw an eye on the CPropertySheet and CPropertyPage classes, these can be customized to appear like a wizard.

Thanks a lot a should do that

use CPropertySheetEx and CPropertyPageEx
that will help you to create office 97 type wizard..perfect look !!!

This is the code that I use in order to backup the little documents used by my programs into a 3 1/2 floppy.
It's placed in a separate thread in order to avoid the hanging effect that produces a long operation and it works perfect while the floppy disk is in the drive.
The problems appear when somebody takes out the floppy disk while the copy operation is taking place.
Here's the code that I use (if you want you can take a look at it in order to see what I can have missed)
ireturn = CopyFile(csFullPathSource, csFullPathDestination, FALSE);
if (ireturn == 0)
{
iErrors++;
csAuxiliar += " : registrado error en éste proceso";
bTrobatError = true;
}
dwFileSize = GetFileSize(hLog,NULL);
SetFilePointer (hLog, dwFileSize, NULL, FILE_BEGIN);
WriteFile(hLog,
csLog,
strlen(csLog),
&dwNBWritten,
NULL);
CloseHandle(hLog);
csLog.ReleaseBuffer(0);
Thank you in advance.

If you get an exception when the user removes the floppy, just intercept it in a try{} catch{} routine.

I'm not sure what you're trying to say. Does CopyFile return an error code when the disk is removed whilst it's being written to, or are you saying that no error is recieved?
One problem may be that you don't seem to have any error checking on the part that writes the log file to disk (as this will obviously fail if there is no disk in the drive)

What´s the definition of hLog´? i´m trying to test it...;)
|
|
|
|
|
HANDLE hLog = NULL;
DWORD dwFileSize = 0;
DWORD dwNBWritten = 0;
DWORD dwErrorCopia = 0
Here you have it...
Thank you for your interest...

Hi!!
I have written an application which uses a pointer variable being imported from a dll. The problem is that while debugging there is no problem but when I try to execute the application from command line, it gives invalid memory access error when the imported variable from the dll is accessed. Can any body tell me why this is happening?
Thanks in advance

Hi,
I am trying to use the static library which is having 4 to 5 functions.In
project settings-link tab i gave the library name and i included the header
files also.In spite of that it is giving this linker error.
What to do next.pl help
IPAddr.obj : error LNK2001: unresolved external symbol "struct value_pair *
__cdecl get_data(char * *,int)" (?get_data@@YAPAUvalue_pair@@PAPADH@Z)
|
|

|

Try to add the following declaration:
extern struct value_pair * __cdecl get_data(char * *,int);

I'm sorry, but this isn't a perl forum.
As for your linker error: the linker clearly states it can't find a definition of the (C++ linkage) function. Just a guess, but the lib is a C lib, and the header file declaring this function is missing the needed extern "C" declaration?
#ifdef __cplusplus
extern "C" {
#endif
...
#ifdef __cplusplus
} /* extern "C" */
#endif

I am playing around the Rectanle object.First I am playing horizontally then vertically.How to increase the speed of Emf files play? I am sending small piece of code.
for(j=1;j<=i;j++)
{
SetRect( &rect1,a,c,a+ezpn_frame_edge,c+ezpn_frame_edge);
// Draw the picture.
pDC->SetStretchBltMode(COLORONCOLOR );
pDC->PlayMetaFile(hemf,&rect1);
SetRect( &rect1,a,d,a+ezpn_frame_edge,d+ezpn_frame_edge);
// Draw the picture.
pDC->SetStretchBltMode(COLORONCOLOR );
pDC->PlayMetaFile(hemf,&rect1);
a+=(ezpn_frame_edge);
a+=ezpn_frame_space;
a-=1;

Hi, everyone!
I am reading a simple class (less than 3K) that encapsulates
WIN32 thread API, I have attached the source codes
as the attachment of the post.
Such are my questions:
1. in function _Entry, what is the function of
the statement? I have known the usage of TLS but
do not know why the class use TLS here.
--------
TlsSetValue(sThreadStorageIndex, theThread)
--------
in function GetCurrent, what is the function of
the statement?
--------
TlsGetValue(sThreadStorageIndex)
--------
2. How to use this class? Can you give me a sample?
Thanks in advance,
George

Hi !
1. I have a MFC dialog based app, and I'd like to add a context menu to the RichEditCtrl I use in it. How do I achieve this ?
2. i'd like to know how to rename a CPropertypage before adding it to the CPropertysheet. I have a dialog that I'd like to reuse three time as is but for its name, which i would like to change. 'tried
CPropertypage ppage;
ppage.SetWindowText("New Caption")
which of course crashed, since the dialog has no handle until it is added to the propertysheet. Any idea ?
Thanks

1) I would derivate a new class CMyRichEditCtrl from CRichEditCtrl, adding these functionnalities
void CMyRichEditCtrl::OnRButtonDown(UINT nFlags, CPoint point) <br />
{<br />
CPoint local = point;<br />
ClientToScreen(&point);<br />
GetParent()->SendMessage(WM_CONTEXTMENU, (WPARAM) GetParent()->GetSafeHwnd(), <br />
MAKELPARAM(point.x, point.y));<br />
CRichEditCtrl::OnRButtonDown(nFlags, local);<br />
}<br />
<br />
LRESULT CMyRichEditCtrl::DefWindowProc(UINT message, WPARAM wParam, LPARAM lParam) <br />
{<br />
<br />
if(message == WM_CONTEXTMENU){<br />
GetParent()->SendMessage(WM_CONTEXTMENU, wParam, lParam);<br />
return(0);<br />
}<br />
else<br />
return CRichEditCtrl::DefWindowProc(message, wParam, lParam);<br />
}
The dialog class then implements the answer to the "Context Menu" message (m_RichEdit is an instance of CMyRichEditCtrl):
void CMyDialog::OnContextMenu(CWnd* pWnd, CPoint point) <br />
{<br />
if (point.x == -1 && point.y == -1){<br />
CRect rect;<br />
m_RichEdit.GetClientRect(rect);<br />
m_RichEdit.ClientToScreen(rect);<br />
point = rect.TopLeft();<br />
point.Offset(5, 5);<br />
}else{<br />
CRect codeWindowRect;<br />
<br />
m_RichEdit.GetWindowRect(&codeWindowRect);<br />
if(!codeWindowRect.PtInRect(point))<br />
return;<br />
}<br />
<br />
<br />
CMenu menu;<br />
VERIFY(menu.LoadMenu(IDR_CONTEXT_MENU));<br />
<br />
CMenu *pPopup = menu.GetSubMenu(SUB_CCODE);<br />
ASSERT(pPopup);<br />
<br />
long lStart, lEnd;<br />
m_RichEdit.GetSel(lStart, lEnd);<br />
pPopup->EnableMenuItem(IDC_COPY, <br />
MF_BYCOMMAND | ((lStart != lEnd) ? MF_ENABLED : MF_DISABLED | MF_GRAYED));<br />
pPopup->EnableMenuItem(IDC_CUT, <br />
MF_BYCOMMAND | ((lStart != lEnd) ? MF_ENABLED : MF_DISABLED | MF_GRAYED));<br />
pPopup->EnableMenuItem(IDC_PASTE, <br />
MF_BYCOMMAND | ((m_RichEdit.CanPaste()) ? MF_ENABLED : MF_DISABLED | MF_GRAYED));<br />
pPopup->EnableMenuItem(IDC_CLEAR, <br />
MF_BYCOMMAND | ((lStart != lEnd) ? MF_ENABLED : MF_DISABLED | MF_GRAYED));<br />
pPopup->EnableMenuItem(IDC_UNDO, <br />
MF_BYCOMMAND | ((m_RichEdit.CanUndo()) ? MF_ENABLED : MF_DISABLED | MF_GRAYED));<br />
<br />
pPopup->TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON, point.x, point.y, this);<br />
}
The dialog class implements also the code for the different menu items.
2) A variation could be to do the "SetWindowText" in the CPropertyPage::OnInitDialog, where the Property Page has a valid HWND.

1) Merci beaucoup . I've also found an article on CP about that inbetween, however your solution seems more precise.
2) That's what I thought. I've also tried it (forgot to mention it), like this :
In Dialog
CPropertypage shdlg;
shdlg.m_NewTitle="Hello World"; In CPropertypage::OnInitDialog
SetWindowText(m_NewTitle);
This does not throw an exception, but does not change the title neither.

we are developing an e-mail client in school, and I wonder how to authentificate to the mail-server, if sending an mail from home. My teacher said, I have to do a pop3 before I send the mail, but that didn't work (I didn't exactly understood what he means...)
..and now I'm here and asking some real IT-gurus...
thanks

I assume you're recieving email from the server using pop3, and sending it using smtp?
Basically, some smtp servers will only allow you to send an email if they recognise that you're a valid user. However, smtp doesn't have any kind of login system, so instead you must first connect and login to their pop3 server, then the smtp server will allow you to send mails
