In that case look for a slightly older version of the same file under :-

hi
i have wrote a function in vc++ not to allow any special characters in flex grid except alphabets &"_".
but if the shift key is pressed and the other keys are pressed it is allowing the special characters.(foe eg '@','#','$')
can u please suggest what is wrong with this code and clear my doubt.
yours friendly

BOOL CCharacterEdit::PreTranslateMessage(MSG* pMsg)
{
// TODO: Add your specialized code here and/or call the base class
if(pMsg->hwnd != NULL && pMsg->message == WM_KEYDOWN)
{
WORD ch =0;
ch = LOWORD(pMsg->wParam);
EnableEditOptions(this,pMsg);
if( !(GetStyle() & ES_NUMBER))
{
CString sEdText;
GetWindowText(sEdText);
if ( ( ( ch >= 48 ) && ( ch <= 57 ) ) ||
( ( ch >= 65 ) && ( ch <= 90 ) ) || // ascii code To allow only alphabets & '_'
( ( ch >= 97 ) && ( ch <= 122) ) ||
( ch == 45 )
);
else if( (ch >= VK_LEFT && ch <= VK_DOWN) || (ch == VK_BACK || ch == VK_DELETE|| ch==VK_TAB))
return FALSE; // allow arrow keys and backspace.
else
{
pMsg->wParam = MAKEWPARAM(0,HIWORD(pMsg->wParam));//make the char value as 0
TRACE("\n After changing char = %d ",pMsg->wParam);
}
}
}
return GetParent()->PreTranslateMessage(pMsg);
}

How can I get info about printer paper tray alignment under W2k, XP ? It was possible to do it (Win98, 95, ME) using DeviceCapabilities with DC_BINADJUST parameter, but this one is now not supported. I need to know it when printing on custom-size paper to set starting offset.
Thanks

Hi,
I have a tree control and I am handling in place edit by overriding the methods OnBeginLabelEdit() and OnEndLabelEdit(). Before editing, I am storing the current name in a member variable "m_strPrevName". While editing, when I press Esc key, I am setting the previous name as shown below.
CMyTreeCtrl::OnEndLabelEdit(NMHDR* NMHDR, LRESULT* Result)
{
if (pTVDispInfo->item.pszText == NULL)
{
// yes. User pressed Esc key. Set the previous name
SetItemText(childItem, m_strPrevName);
*Result = 1;
}
}
The SetItemText() method is returning true, but the treeitem is not updated and it is NULL. How can I set the previous name??

In this case, you have probably set the text for the wrong item ... check if the handle (childItem in your code) is really the good one. Be careful to the difference between Item index and handle.

Hello,
First of all, I want to sorry about my terrible English.
Next, please show me the way to get the information of the printer.
Ex: When the user print his/her document (or anything else), my program catches this event and determining the total of printed pages for calculating cost.
If applicable, please give me the VC++ source code.
Thank you very much.

What kind of info do you want? Some information is harder to get then others.

I only want the total of printed pages.
Ex: My program will start automatically every time Windows loads. During the Windows session, when user print his/her documents, my program will show the total of printed pages and the total cost of them.
Here is an output example:
Print time: 12:22:00
Document: letter.doc
Cost per page: 5
Total page(s): 3
Total cost: 15

ok, I'm working in win32 here, no MFC, when trying to create a listview control in a class I get the following err:
First-chance exception in pool.exe (COMCTL32.DLL): 0xC0000005: Access Violation.
Now, this err is on Win98 with IE 5.01
the code works fine on WinXP with IE6
it errs right on CreateWindowEx().
I tried just starting a new win32 app and cutting n pasting the code to create the listview n it works fine on that Win98. So my question is what could be the problem, is it the class?
|
|
|
|
|
|
I do call InitCommonControlsEx already, thats why it works when I try it outside of the class and why I don't get why it'd be causing that err.
|
|
|
|

does anyone code on Win98 anymore?
after hours trying to pinpoint the problem I found this: if I set the handle of the parent in CreateWindowEx() to that of a window created in a class it fails, setting the handle of a global parent works ok, so is this a known problem on 98?
CreateWindowEx(....., CWinA::hWnd,...) fails
CreateWindowEx(....., ghWnd,...) is ok
and yes, CwinA::hWnd is a static public member of the class, so I'm at a loss as to the problem, I'm looking for any ideas here ppl

How did you find out that it was SetClipboardViewer() ? The function returns NULL when it fails, but usually does not crash the app, unless you are doing something related to it just after. So I´m wondering ... Could you post a code sample about how you use it ?

It seems that when I add to a TreeControl (Win32 SDK not MFC) the pszString item I add is not the same was what I put in (eg. Put in text and get back a large string of hi-ascii).
I insert into the tree thusly:
<br />
TVINSERTSTRUCT tvs;<br />
TVITEM tvi;<br />
HTREEITEM last;<br />
<br />
tvs.hInsertAfter = TVI_LAST;<br />
tvi.mask = TVIF_TEXT;<br />
<br />
tvi.pszText = "Test Item #1";<br />
tvs.hParent = TVI_ROOT;<br />
tvs.item = tvi;<br />
last = TreeView_InsertItem(GetDlgItem(MainWindow,IDC_TREE),&tvs);<br />
To retrieve I handle the WM_NOTIFY message when the event is TVN_SELCHANGED.
<br />
case WM_NOTIFY: <br />
node = (LPNMTREEVIEW)lParam;<br />
if(node->hdr.code == TVN_SELCHANGED) {<br />
MessageBox(MainWindow,(char *)node->itemNew.pszText,"Selection CHANGED!",0);<br />
}<br />
break;<br />
In the debugger node->itemNew.pszText is high ascii garbage and no where near the "Test #1" item I put in. The book I have and the docs I've found so far all use the TreeControl by comparing the selected item to a list of the items added which is no good for me because I'm trying to build up the entire path from each selected tree item (like a file path). This occurs with multiple items in the tree control as well.
Any suggestions or ideas on where I have gone wrong would be greatly appricated.

Rule #1 of the list/tree control structs is: always init them to zero. You'd be surprised how much havoc is wrought if you don't do that.
TVINSERTSTRUCT tvs = {0};
TVITEM tvi = {0};

That must be because you are simply not looking at the good item. I do not know enough about non MFC app to be of a great help, but try to see if the lines
node = (LPNMTREEVIEW)lParam;
if(node->hdr.code == TVN_SELCHANGED) {
MessageBox(MainWindow,(char *)node->itemNew.pszText,"Selection CHANGED!",0);
}
really refers to the correct item.

I would suggest that where you have gone wrong is to assume the pszText member of itemNew is valid, it isnt. See the MSDN Library topic for TVN_SELCHANGED.
Try it like this:
if(node->hdr.code == TVN_SELCHANGED) {
node->itemNew.mask |= TVIF_TEXT;
TreeView_GetItem(GetDlgItem(MainWindow,IDC_TREE),&node->itemNew);
MessageBox(MainWindow,(char *)node->itemNew.pszText,"Selection CHANGED!",0);
}
|
|

Ok. That seem to do it and according to the help file I ended up with:
<br />
HWND ctrl = GetDlgItem(MainWindow,IDC_TREE);<br />
char buffer[1024];<br />
memset(buffer,0,1024);<br />
if(ctrl == NULL)<br />
MessageBox(MainWindow,"GET TREE","Selection CHANGED!",0);<br />
node->itemNew.mask |= TVIF_TEXT;<br />
node->itemNew.pszText = buffer;<br />
node->itemNew.cchTextMax = 1024;<br />
if(TreeView_GetItem(ctrl,&node->itemNew))<br />
MessageBox(MainWindow,(char *)node->itemNew.pszText,"Selection CHANGED!",0);<br />
This works fine but it seems from the Help files regarding TVITEM suggest than I can only "tell" if an item has a child. Is there a way to use the control itself to follow the lineage of the selected item? For arguments sake let's just say i'm trying to implement a file browser (not the case but the same idea). If I choose a file I need to build up the entire path based on the selection back to through the parents to the root. Do I have to "already know" the structure of the tree already? Having two copies (one in the tree control itself and the other in my program) of the same tree in memory seems to be a waste and terribly inefficient which is why I'm trying to just use the data in the treecontrol instead of building a tree data structure in memory which is replicated to the treecontrol.
Man that's wierdly stated hopefully I'm making some sort of sense here.

Sean,
Either way is messy, keeping a copy of the structure in memory or using the control.
Look to continuously call TreeView_GetParent() until it returns NULL. If you use a loop you will need to insert the parent item's text at the beginning of the buffer each time. If you use a recursive function call then you can build the string by appending each item's text on the way back out of the recursive function.
|

That's exactly what I'm looking for and using GetParent doesn't sound as messy as a tree comparisson unless of course the control itself doesn't handle it well.
I'd have to do a recursive match either way so I'll let the control do most of the work.
Thanks a million none the less.
