Question

Need some help with ComboBox and Column

Asked by: tsp2002

Hello,
Zoppo I have a new question regarding the combobox with column.
--------------------------------------------------------------------------------
How can I send a CString with SetDlgItemText to a Editbox in my Dialog.
in my virtual function SelectCurrentItem()' at my new class?

I always get an error that my program don´t know the resource ID.

500 points.
Best regards,
Thomas

Hi tsp2002,
 
ok, to derive your own class it's simply enough to do something like this:
 
Create two new files:
1. MyMultiColumnComboBox.h
> #pragma once
>
> class CMyMultiColumnComboBox : public CMultiColumnComboBox
> {
> public:
>  virtual void SelectCurrentItem();
> };
 
2. MyMultiColumnComboBox.cpp
> #include "stdafx.h"
> #include "MultiColumnComboBox.h"
>
> void CMyMultiColumnComboBox::SelectCurrentItem()
> {
>  int nIndex = GetCurrentItem();
>
> CString strText;
> CListCtrl* pList = GetListCtrl();
>
> if ( NULL != pList && nIndex >= 0 )
> {
>  strText.Format( "%s, %s, %s", pList->GetItemText( nIndex, 0 ), pList->GetItemText( nIndex, 1 ), pList->GetItemText( nIndex, 2 ) );
> }
>
> GetEdit()->SetWindowText( strText );
>
> // this is copied from original source
> if (nIndex >= 0)
>  if (CWnd* pParent = GetParent())
>   pParent->SendMessage(m_nSelChange, (WPARAM)GetDlgCtrlID(), (LPARAM)m_hWnd);
> }
 
Then where you now use CMultiColumnComboBox replace
> #include "MultiColumnComboBox.h"
with
> #include "MultiColumnComboBox.h"
 
and
> CMultiColumnComboBox m_wndCombo; // or whatever name you use
with
> CMyMultiColumnComboBox m_wndCombo;
 
This should do the job ...
 
Hope that helps,
 
ZOPPO

Hi tsp2002,

could you post the 'SelectCurrentItem' as you use it now?

I guess the ID you pass to SetDlgItemText doesn't exist? Is it the edit box of the multi-column combo box or any other edit box in the dialog?

ZOPPO

by: tsp2002Posted on 2009-10-26 at 07:01:07ID: 25662273

The ID exist....it is a Editbox of my Dialog

SetDlgItemText(IDC_EDIT_ADRESSE_RECHNUNG_ID, "just a try"); will not find this ID

this is the header of the new class from MultiColumnComboBox

class CMulti_Column_ComboBox_NEU :
	public CMultiColumnComboBox
{
public:
	CMulti_Column_ComboBox_NEU(void);

Select all Open in new window

by: ZoppoPosted on 2009-10-26 at 07:05:43ID: 25662316

Hi,

this cannot work since the edit box is part of the dialog, not of the CMulti_Column_ComboBox_NEU from where you call it.

You can try this instead:

> GetParent()->SetDlgItemText(IDC_EDIT_ADRESSE_RECHNUNG_ID, "just a try");

Hope that helps,

ZOPPO

by: tsp2002Posted on 2009-10-26 at 07:10:04ID: 25662366

will not work... same result

by: tsp2002Posted on 2009-10-26 at 07:12:04ID: 25662387

does the header have something to do with that....even I enclose the header....same result

#include "Geschaeftsadressen.h" ....that is the class of the dialog where the ComboBox is and the Editbox

by: ZoppoPosted on 2009-10-26 at 07:33:45ID: 25662604

Hm - just tested it and in my case it works ok.

Do you still get error that the resource ID wasn't found? Or is it that just the text doesn't appear?

In the first case I can imagine two reasons why this doesn't work for you:
1. The edit box with ID 'IDC_EDIT_ADRESSE_RECHNUNG_ID' is not a control in the multi-column combo box's parent window
2. The 'SelectCurrentItem' is called before the dialog is finally created.

If 1. is not the case (you have to know if it's wrong) I'd suggest to replace your call to 'SetDlgItemTest' with this code:

> CWnd* pParent = GetParent();
> if ( NULL != pParent )
> {
> CWnd* pEdit = pParent->GetDlgItem( IDC_EDIT_ADRESSE_RECHNUNG_ID );
> if ( NULL != pEdit )
> {
> pEdit->SetItemText( "Just a try!" );
> }
> }

BTW: It shouldn't matter if you include the dialog's class header since this functionality simply acts on the control's windows, so only the control ID has to be known at this place ...

ZOPPO

by: tsp2002Posted on 2009-10-26 at 07:46:14ID: 25662732

sorry...but still the same

Do you still get error that the resource ID wasn't found? Or is it that just the text doesn't appear?.....the resource ID is not found

also I got a new error

'SetItemText': Is no Element of 'CWnd'

2. The 'SelectCurrentItem' is called before the dialog is finally created.
No....the dialog with my Editbox is there

by: ZoppoPosted on 2009-10-26 at 07:58:07ID: 25662871

Sorry, it's 'SetWindowText', not 'SetItemText' ...

Do you use something like a child dialog as parent for either the combo box or the edit control?

Can you check if the edit control and the combo box have the same parent window (the dialog) and the resource ID of the edit box really is IDC_EDIT_ADRESSE_RECHNUNG_ID? You can check both with 'Spy++' which is part of Visual Studio ...

ZOPPO

by: tsp2002Posted on 2009-10-26 at 08:00:00ID: 25662895

here are my new class with header and the start of my Dialogclass where the combobox and editbox are located.

....will work tomorrow again....I am on the run.....talk tommorrow.....thank you

Select all Open in new window

.......Can you check if the edit control and the combo box have the same parent window (the dialog) and the resource ID of the edit box really is IDC_EDIT_ADRESSE_RECHNUNG_ID? You can check both with 'Spy++' which is part of Visual Studio ...

Good Morning Zoppo,

I don´t know where to find and how to use the Spy++? Please advise.

My Visual Studio is 2003 Version 7.1.6030 Net Framework 1.1

by: ZoppoPosted on 2009-10-27 at 03:00:51ID: 25670600

Hi,

unfortunateley I can't exactly say where Spy++ is in VS 2003 - in VS 2005 and VS 2008 you can find it in the start menu 'Microsoft Visual Studio 2008->Visual Studio Tools'.

To find out the thing I asked you should comment out the code which makes problems so you can open the dialog without error, then in Spy++ you can use 'Search->Find Window' to get information about the both controls, i.e. see if they have the same parent and see the value of the 'Control-ID' of the edit control so you can compare it with the value defined for 'IDC_EDIT_ADRESSE_RECHNUNG_ID' in resource.h.

ZOPPO

by: tsp2002Posted on 2009-10-27 at 03:34:06ID: 25670773

resource.h.

#define IDC_EDIT_ADRESSE_RECHNUNG_ID 1332

please look at my hardcopies.....but I don´t know what to look for?????

ok, so far so good - easiest to find this out is to do following:

- start you application and open the dialog in question
- start Spy++ and select 'Search -> Find Window' (as shown in your second screenshot)
- Take the small cross hair at the right side of 'Suchtool:' with the mouse and drop it above the edit control 'IDC_EDIT_ADRESSE_RECHNUNG_ID'
- Now in the main window of Spy++ an entry containing info about that edit control should be selected - right click it and select 'Properties', then you should be able to see the 'Control ID' of the edit control in the up coming properties window's first tab.
- Next do the same (Search -> Find Window) and select the combo box in question - check that it has the same parent node as the edit control has.

ZOPPO

by: tsp2002Posted on 2009-10-27 at 05:54:05ID: 25671804

That's ok, they must not have the same since they are two differen controls.

At least we now see the edit control has the correct ID (since 1332 == 0x534). Now you need to check whether these two controls have the same parent (which should be the dialog) - you can check it in the tab 'Fenster'.

ZOPPO

by: tsp2002Posted on 2009-10-27 at 06:17:58ID: 25672036

if we stuck here.....can I not call a function in Geschaeftsadressen.cpp

to add the CString that I will set to IDC_EDIT_ADRESSE_RECHNUNG_ID

void CMulti_Column_ComboBox_NEU::SelectCurrentItem(void)
{
int nIndex = GetCurrentItem();
CString strText;
CListCtrl* pList = GetListCtrl();
//------------------------------------------------------------------
if(NULL !=pList && nIndex >=0)
{

strText.Format("%s, %s, %s, %s", pList->GetItemText(nIndex,1),
pList->GetItemText(nIndex,2),
pList->GetItemText(nIndex,3),
pList->GetItemText(nIndex,6));

}
//------------------------------------------------------------------
GetEdit()->SetWindowText(strText);

CGeschaeftsadressen::Get_Adresse_ID_Rechnung(strText);

}

CGeschaeftsadressen::Get_Adresse_ID_Rechnung(strText);
================================================

but that will not work....I also got an error when I enclose Geschaeftsadressen.h

ok, still strange - IMO it should work - we now verified the edit control has the correct ID and is a sibling control of the combo box, so this code should in general work:

> void CMulti_Column_ComboBox_NEU::SelectCurrentItem(void)
> {
>
> ... // other stuff
>
> CWnd* pParent = GetParent();
> ASSERT( NULL != pParent );
> if ( NULL != pParent )
> {
> CWnd* pEdit = pParent->GetDlgItem( IDC_EDIT_ADRESSE_RECHNUNG_ID );
> ASSERT( NULL != pEdit );
> if ( NULL != pEdit )
> {
> pEdit->SetWindowText( "Just a try!" );
> }
> }

>> can I not call a function in Geschaeftsadressen.cpp
That's just what we try here - with 'GetParent' you should get a pointer to the parent dialog (which should be a 'CGeschaeftsadressen' instance). With 'GetDlgItem' we try to achieve a pointer to a CWnd representating the edit control with the ID 'IDC_EDIT_ADRESSE_RECHNUNG_ID'. Then the 'SetWindowText' should set the edit control's text.

IMO this is quite strait forward - I did such thing hundreds of times without problems - but it's hard to say what's going wrong within your code without seeing it completely and without the possibility to debug it ...

Regards,

ZOPPO

by: tsp2002Posted on 2009-10-27 at 07:00:21ID: 25672482

did you tried the same....I mean perhaps this strange thing comes from the customID, Subclass and multicolumncombobox class?

if not....is there any other way .... when the user changes/takes a choice of the MultiComboBox... that I got a notice in Geschaeftsadressen.cpp...thanks

by: ZoppoPosted on 2009-10-27 at 07:13:56ID: 25672622

I did exactly the same - I have a multi column combo box with three columns and a edit control within a dialog.

Attached you can see the 'SelectCurrentItem' I use - it works like a charm. IMO anything about the multi column combo box (ID, subclass a.s.o.) shouldn't matter, as long as the correct 'SelectCurrentItem' is called it should be possible from there to set the edit control's text.

ZOPPO

void CMyMultiColumnComboBox::SelectCurrentItem()
{
	int nIndex = GetCurrentItem();
 
	CString strText;
	CListCtrl* pList = GetListCtrl();
 
	if ( NULL != pList && nIndex >= 0 )
	{
		strText.Format( "%s, %s, %s", pList->GetItemText( nIndex, 0 ), pList->GetItemText( nIndex, 1 ), pList->GetItemText( nIndex, 2 ) );
	}
 
	GetEdit()->SetWindowText( strText );
 
	GetParent()->SetDlgItemText( IDC_EDIT_TEST, "Just a try!!!" );
 
	//Notify the parent that one item was changed
	if (nIndex >= 0)
		if (CWnd* pParent = GetParent())
			pParent->SendMessage(m_nSelChange, (WPARAM)GetDlgCtrlID(), (LPARAM)m_hWnd);
}

or does that have something to do with it.....this is the way I call CGeschaeftsadressen Dialog from CMainFrame??? I am fishing....

by: ZoppoPosted on 2009-10-27 at 07:29:00ID: 25672779

I don't think this should affect what happens within the dialog - just for testing you could change implementation to use the dialog as a modal one, i.e. add these lines at the beginning of that function:

> CGeschaeftsadressen dlg;
> dlg.DoModal();
> return;

I don't think this makes a difference, but who knows - after testing you can delete these lines again.

BTW: Could you please post again the current version of the 'SelectCurrentItem' you use?

ok, what happens if you uncomment the second part which start with 'CWnd* pParent = GetParent();'? Do you see an ASSERTION?

by: tsp2002Posted on 2009-10-27 at 07:51:31ID: 25673022

CWnd* pParent = GetParent();
ASSERT( NULL != pParent );

you mean this alone? no stop or error

Do you see an ASSERTION?Sorry don´t know what that means

by: ZoppoPosted on 2009-10-27 at 08:04:54ID: 25673198

I meant if you use the complete attached code.

With assertion I meant if a dialog pops up looking like the attached bitmap - this will only happen if your application is built using the DEBUG configuration ...

...
 CWnd* pParent = GetParent();
 ASSERT( NULL != pParent );
 if ( NULL != pParent )
 {
  CWnd* pEdit = pParent->GetDlgItem( IDC_EDIT_ADRESSE_RECHNUNG_ID );
  ASSERT( NULL != pEdit );
  if ( NULL != pEdit )
  {
   pEdit->SetWindowText( "Just a try!" );
  }
 }

I changed my project to debug modus.....

When I put here a breakpoint
SelectCurrentItem(void)
GetEdit()->SetWindowText(strText); <--------------- it stops

but it will not stop
CWnd* pParent = GetParent();
ASSERT( NULL != pParent );..... see bitmap breakpoint with ?

When I start the debug ..... I got the error with the ID.....when I then press continue.....

the program runs.....but no effect of the GetParent code

proberties of Object...can not change to debug

by: ZoppoPosted on 2009-10-28 at 02:48:48ID: 25681311

So you mean your project doesn't compile in DEBUG configuration? That's not good ... I guess that the breakpoints aren't hit because the build failed so the previously built EXE is executed which has no relation to the changed code - you should try to resolve the compile errors in DEBUG configuration ...

Well, since I find it's quite difficult to solve this problem without a chance to test it I want to ask you if you either could attach your project here within a ZIP file (if it's not too large or too secret) or if you could try to make a small new test project with just one dialog, one multi colum combo box (which should use your current CMulti_Column_ComboBox_NEU class) and an edit box. If you get setting the text working maybe you can find the difference yourself, if you have the same problems in that test project you could attach it here so I could try to find the problem here ...

Hello Zoppo,

thanks for your offer. The thing is that today is my last day before my vacation.

I am going on vacation tomorrow for 2 1/2 weeks.

I give you the points....even if we didn´t find a solution. I try to send you a text object....but I don´t know if I have enough time....because of my last day before vacation and I am in my office....had have some work to do.

If not....I will ask the question in mid. Nov. again.

Best regards,

Thomas

by: ZoppoPosted on 2009-10-28 at 04:14:39ID: 25681898

Well, I don't have a problem if we just keep this question open - no need to give me points before it's solved.

IMO it's even better to keep this question open since without a solution it shouldn't be moved to the PAQ.

I wish you a nice vacation ...

best regards,

ZOPPO

by: tsp2002Posted on 2009-10-28 at 05:22:18ID: 25682396

okay...great....I forgot that I have a sample of the program just on Dialog.....

I just added a Editbox.....same result as my main program....can not find ID

I just tried to add my zip....but this site will not allow my files

The extension of one or more files in the archive is not in the list of allowed extensions: ComboBox_with_Column.cpp

by: tsp2002Posted on 2009-10-28 at 06:04:45ID: 25682742

Hello Zoppo,

I am back from my nice vacation.

I post all my steps (step by step) for you. If you do the same you should not be able to send the example text to the Editbox. Is there a mistake in my steps?

Please let me know. Thank you.

Hi again,

seems you enjoyed your vacancy ...

Well, I'm a little bit off-topic, but as far as I can see this are the same steps I did - and for me it works.

Just to clearify: This sample does compile well but no text appears in the edit box, right?

Are you now able to build that application as a DEBUG build? If so you should debug through the CComboBoxNEU::SelectCurrentItem.

ok, this means the project doesn't compile, the reason is 'error C2065: 'IDC_EDIT1': nichtdeklarierter Bezeichner'

IMO the problem is that 'resource.h' isn't included in ComboBoxNEU.cpp - just add this line
> #include "resource.h"
somewhere below the line
> #include "stdafx.h"
(somehow like in the attached code)

I hope this helps,

ZOPPO

#include "stdafx.h"
#indlude "resource.h"
#include "ComboBoxNEU.h"
