Hi!
I need free grid control with grouping function.
Thanks for any help.

look in the most popular section, Chris's article

i think that you dont understand what i need, i know about this grid but you can not group by field like most of commercial functions have.
I need grid with internal grouping

Problem with templates<> and classes
I have this kind of class (first of all - I use VC++.NET)
class XMLParser
{
struct Scene
{
LinkedList< SceneObject > objectList;
}
struct SceneObject
{
}
LinkedList< Scene > sceneList;
XMLParser
~XMLParser();
//
static void StartElementHandler(void * data,
const char * element,
const char ** attribute);
static void EndElementHandler( void *data,
const char *el );
}
I'm using the expat library for XML parsing. This class should parse an .xml file and create a list of scenes.
XMLParser constructor initializes the expat XML parser and the StartElementHandler and EndElementHandler are callbacks that handle the parsing needed by expat.
The problem is the templated LinkeList class. I want to "new LinkedList< Scene >()". I can't do it inside the class decalration and I can't do it outside of the class declaration. In the first case I get a compiler error (obviously) and in the second one a linker error.
If I do:
XMLMovieParser::sceneList = new LinkedList< Scene >();
I get C2512 no appropriate default constructor available
and C2955 use of class template requires template list
If I do inside the constructor:
sceneList = new LinkedList< Scene >();
I get an unresolved external symbol errors: LNK2001 and LNK2019
etc.
the full class is too long to post

This surely is not the whole answer to the question, but
sceneList = new LinkedList< Scene >(); is trying to assign a LinkedList< Scene > pointer to a LinkedList< Scene > object.
Check the definition for LinkedList. If you've got some references around, the compiler won't be able to generate a default constructor, maybe this is the problem.

LinkedList< Scene > sceneList;
this should be of course a pointer
LinkedList< Scene > *sceneList;

I have a rich-edit where I only want to support *one* font (Tahoma 10pt. etc.) set up at time of constructing of the edit. This works fine when writing in it.
But how do I force my text into this specific font and look when pasted in - from some other size and font?
Think it's something about monitoring the clipboard format but I'm not sure?

Handle OnPaste(), and add the text yourself (so do not do the call to the base class)
~RaGE();
|
|
|
|
|
Where is OnPaste() a member?
Not in CWnd nor in CRichEdit - last one have a Paste() only?
As far as I can see in CWnd I have:
ChangeClipboardChain(...)
SetClipboardViewer(...)
OpenClipboard(...)
GetClipboardOwner(...)
GetOpenClipboardWindow(...)
GetClipboardViewer(...)
and in CRichEdit:
Copy(...)
Cut(...)
Paste(...)
PasteSpecial(...)
CanPaste(...)
I'm a little puzzled here - I can understand what you are thinking, but...
(working with MFC 6.0 not .net)

I've got a problem with painting.
I'm currently using the dev-IL image library to load and paint images. If I use the main dialog's HWND to paint on, the image is visible rightaway. But, I created a static and if I use it's HWND, it will only paint the image after a to front of the dialog (with CTRL-TAB). Although I've included a Validate after the paint.
How can I tell the static to update/repaint/validate?
I've already tested some things I found here, but doesn't work.
tnx.
using: [VISUAL STUDIO 6.0 sp5] [WIN98/2]

You should not Validate() it, but Invalidate() it.
~RaGE();

Hi,
As I want to get two strings from a txt with the following format:
Hello
Welcome
I used :
FILE *stream;
fgets(tmp, 100, stream);
fgets(temp, 100, stream);
to get the first and second strings. I know that by using the fgets, I will also get the newline character which happened in the first string.
Is there any other methods, so that I can get the actual string (without newline character)?
Thx

I create a tri-splitter view with a CIndexView(with TVS_EDITLABELS style) in each pane, but when I click the mouse over the editbox, there is an illegal operation. the code is as following: (VC6, Debug configuration),Thanks very much!
int CTriSplitView::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CView::OnCreate(lpCreateStruct) == -1)
return -1;
// Create the splitter wnd.
m_wndSplitter.CreateStatic(this, 1, 2);
// add the third splitter pane - which is a nested splitter with 2 rows
if (!m_wndSplitter2.CreateStatic(&m_wndSplitter, // our parent window is the first splitter
2, 1, // the new splitter is 2 rows, 1 column
WS_CHILD | WS_VISIBLE | WS_BORDER, // style, WS_BORDER is needed
m_wndSplitter.IdFromRowCol(0, 1))) // new splitter is in the first row, 3rd column of first splitter
{
TRACE0("Failed to create nested splitter\n");
return -1;
}
CCreateContext *pContext = (CCreateContext*)lpCreateStruct->lpCreateParams;
if (!m_wndSplitter.CreateView(0, 0, RUNTIME_CLASS(CTreeView), CSize(150, 0), pContext))
{
TRACE0("Failed to create COutlookTreeView\n");
return FALSE;
}
if (!m_wndSplitter2.CreateView(0, 0, RUNTIME_CLASS(CTreeView), CSize(0, 450), pContext))
{
TRACE0("Failed to create COutlookTreeView\n");
return FALSE;
}
if (!m_wndSplitter2.CreateView(1, 0, RUNTIME_CLASS(CTreeView), CSize(0, 0), pContext))
{
TRACE0("Failed to create COutlookTreeView\n");
return FALSE;
}
DWORD dwTreeStyle = WS_VISIBLE | TVS_EDITLABELS;
dwTreeStyle |= TVS_HASBUTTONS | TVS_HASLINES | TVS_LINESATROOT;
CTreeView* pView = (CTreeView*)m_wndSplitter.GetPane(0, 0);
pView->ModifyStyle(0, dwTreeStyle);
for(int i = 0; i < 10; i++)
{
CString str;
str.Format("%d", i);
pView->GetTreeCtrl().InsertItem(str);
}
return 0;
}
P.S. If above codes are placed in CMainFrame::OnCreateClient, It does work with no problem

sorry, there is an error:
I create a tri-splitter view with a CTreeView(with TVS_EDITLABELS style) in each pane,

 Anybody... I have a multiple program that access the same database file. I am using access database file and CRecordset class to implement my program. However, the different program is trying to access the database sometimes at the same time. It always give me an error that the current database file has been locked or currently in use by the user/Admin. Please.. if anybody knows my problem.. I would appreciate it very much !!!
rgrds,

Is the database a single-user one? What mode are you opening the database and/or record set in? Is the database configured to open as shared or exclusive by default?

Hi David,
This is the message i encountered:
"Could not update;currently locked by user 'admin' on machine 'P1-MAR' "
Here is my code....
CTestSummary pTestSummary(NULL); // CTestSummary is derived from CRecordset class
pTestSummary.m_strFilter = "HANDLER_NAME = \'" + current_handler_name + "\'"; // select only target handler
if(pTestSummary.Open(CRecordset::dynaset,NULL)!=0)
{
pTestSummary.Edit(); // open for editing
pTestSummary.m_graph_half1 = half1; //saved the first 240 characters
pTestSummary.m_graph_half2 = half2; // saved the next 240 characters
pTestSummary.m_graph_date_time_stamp = string_default; //saved the current date time stamp
pTestSummary.Update();
}
I have several program that simultaneously edit thesame database file. I have read some documents from CRecordset class
that there will be some problem if Update() function is executed from each program , if just in case they occur at thesame time.
Is there's a way I could get some error trapping when accessing database file so that I could just bypass the Update() function if I
encountered this error. As for now, the default message box by window always show if one of this Update() failed.
Here is the construction of CTestSummary class... I use class wizard to create it..
// TestSummary.cpp : implementation file
//
#include "stdafx.h"
#include "clisock.h"
#include "TestSummary.h"
#ifdef _DEBUG
#define new DEBUG_NEW

#endif
/////////////////////////////////////////////////////////////////////////////

m_graph_half2 = _T("");

}

RFX_Text(pFX, _T("[graph_date_time_stamp]"), m_graph_date_time_stamp);
//}}AFX_FIELD_MAP
}

I would appreciate if you could help me on this...

CRecordset::Update() throws a CDBException if it encounters a problem.

Hey, is it possible to access DLL-function as an extra procress. I need this, because some function within an User-dll are not save. Me goal is to load a DLL in an seperate process in order to prevent a crash from the main application.

Why not just use structured exception handlers instead?
Using this approach a hard exception such as an access violation will be caught by the __catch block and can be handled by your app in any way that's appropriate.
There's plenty on MSDN on this subject. Also check out John Robbin's "Bugslayer" series in MSJ/MSDN Magazine.

I can use excetions in my own code, but when I use foreign DLL function I have no chance to prevent e.g. divsion by zero ...

If you're using C++ exceptions that's certainly true - they won't catch "hard" exceptions such as access violations.
However, a Structured Exception Handler will. Simply wrap the calls into the DLL inside an SEH __try block.
