this was my origional idea, but i don't understand how i can trap both the ctrl and the g at the same time. in OnChar, the variable nChar is only one value, correct? unless i'm mistake, how can i look for 2 keys at the same time?

You can't, unless they are keys like Ctrl, Shift, and Alt, which can be pressed simultaneously.
In your character-detection code:
if (Ctrl+g was pressed)
set flag = T
else
{
if (d was pressed)
{
if (flag equals T)
}
else
set flag = F
}Make sense?

I am having touble developing a MFC project to switch images on tool bar buttons. First I can not get the following code to display predefined bitmap images in the toolbar.
The desired result of this code is, of course, to produce the desired images on the tool bar and then have the images switch as the tool bar button is toggled... the toggling code will be implimented in an OnUpdateUI handler which is another part of this project.
The updating code will look something like this...
void CMainFrame::OnUpdateSwitch_134(CCmdUI* pCmdUI)
{
m_bSwitch134 = !m_bSwitch134;
if( m_bSwitch134)
SwitchToolBar.OnChangeButton( IDB_ON, 1, RGB(0,0,0));
else
SwitchToolBar.OnChangeButton( IDB_OFF, 1, RGB(0,0,0));
}
This code compiles fine but the tool bar is blank...
Would appreciate any comments or help.
Thanks...
Ozzy
CToolBarCtrl SwitchToolBar;
CImageList* m_ptrImageList;
CImageList SwitchImageList;
int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
TBBUTTON tb;
if (CFrameWnd::OnCreate(lpCreateStruct) == -1)
return -1;
// create CToolBarCtrl toolbar
SwitchToolBar.Create(WS_CHILD|WS_VISIBLE|WS_BORDER|TBSTYLE_FLAT,
CRect(0,0,0,0), this, IDR_TOOLBAR1);
// create ImageList from IDB_SWITCH_IMAGES
SwitchImageList.Create( IDB_SWITCH_IMAGES, 20, 1, RGB(192,0,192));
// get image list pointer
m_ptrImageList = SwitchToolBar.GetImageList();
// set image list for SwitchToolBar
SwitchToolBar.SetImageList( m_ptrImageList );
// assign elements in TBBUTTON structure
tb.iBitmap = 0;
tb.iString = NULL;
tb.fsState = TBSTATE_ENABLED;
tb.fsStyle = TBSTYLE_BUTTON;
tb.idCommand = 0;
// add buttons to list
SwitchToolBar.AddButtons(1, &tb );
return 0;
}

After insert the JpegLib project into my own project, when compiling it there is one error：
\jpeglib\jmorecfg.h(238) : error C2371: 'boolean' : redefinition; different basic types
\vc98\include\rpcndr.h(173) : see declaration of 'boolean'
in jmorecfg.h, it is defined as bellow：
#ifndef HAVE_BOOLEAN
typedef int boolean;
#endif
while in VC rpcndr.h there is another define:
typedef unsigned char boolean;
if I delete two include file, this problem doesn't appear：
#include <afxdisp.h> // MFC Automation classes
#include <afxdtctl.h>// MFC support for Internet Explorer 4 CommonControls
but these two include files is useful for me ,so I can't delete them
if I don't delete these two include files and add
#define HAVE_BOOLEAN
before
#include "jpglib.h"
the redefinition error doesn't appear also, but the Jpeg image can't display correctly, so I need help。

I remember having this problem with the INT32 defintion. I just deleted the entire redefinition in the jpeg library source code and it worked fine.

Ok here is the image so you can see the problems related to the questions:
Image
1- I use this to draw the Check in the menu
DrawFrameControl(lpdis->hDC,&rcCheck,DFC_MENU,DFCS_MENUCHECK | DFCS_TRANSPARENT);
But as you can see I can't have the background color the same as the side bar.
2 - The Submenu Arrow is always drawn, is there a way to prevent windows from drawing it and I would use the same function as the check mark for that too.
3 - The menu Window has a sort of border which match's windows colors, Is there a way that I could paint this border another color to make the menu look like a flat one.
Using Win32 API, no MFC ATL or WTL.
Using Visual Studio .NET 2003, Windows XP SP1
If you need more code or other stuff to help, just say so.
Thank You for any replies

Hi all..
I'm having quite an annoying problem. Every time I use DeleteAllItems() on a tree view in my application, all items I try to add to that tree view afterwards don't show up!
I've made a little MFC example displaying the problem:
http://www.blacksmith-studios.dk/tree_testing.rar
Please read the Readme.txt file before checking out the actual program 
I really hope you guys have some qualified answers, since I cannot understand why this ain't working properly!
Huge thanks in advance!

Grr, yet another simple problem has me floundering at the CP god's feet. I have some radio buttons, and a combobox. If the radio buttons are not checked, the combobox is greyed out. I'm using the line
GetDlgItem( IDC_CAL_TRANSDUCER )->EnableWindow(m_bitControls[bool_cal_xducer]);
to do this. My problem lies with re-enabling it. I have my OnBnClicked() thingamajobber, but i have no idea what to put in there to re-enable it. I've tried a ton of different functions, but they either completely hide the combobox or just don't do anything.
any help?

Instead of GetDlgItem, use a control-variable. Classwizard can make that for you if you tell it to make your variable of type CComboBox (or whatever your control is).
As for enabling:
m_ComboBoxCtrl.EnableWindow(true);
does not work?

yeah i'm using a control variable, i just wrote it like that so it would be a little more clear what i was trying to do

or use ON_UPDATE_COMMAND_UI to get the CCmdUI* pCmdUI.
You could call
pCmdUI->Enable(true) to enable it.
This is applicable to all UI component which response to CCmdUI

I would like to have a "MDI" application that displays a bunch of reports in separate windows within a main frame. I would like to define each report using a dialog resource. This is what I have tried:
1. Create a dialog resource for each report and use classwizard to generate a class for each. The dialogs have the WS_CHILD style.
2. Create a menu resource which will allow selection of each report.
3. Have cwinnapp::initinstance create a CFrameWnd and add the menu to it.
4. When the user selects one of the reports from the menu then display the associated report dialog modelessly with the main cframewnd as the parent.
This sort of works. The problem is that the modeless dialog never gets the focus (even when I click on it). Is there a way to fix this or is there a better way to do this?
|

What are you using to create the dialog? are you using
m_your_dialog.Create();
m_your_dialog.ShowWindow(SW_SHOW);
This is how i create my modaless diags, and it brings them into focus automatically.

I have tried that, no luck.
My current code is:
if(rpt_cpu_category == NULL) {
rpt_cpu_category = new dlg_rpt_cpu_category;
rpt_cpu_category->Create("RPT_CPU_CATEGORY",this);
}
rpt_cpu_category->BringWindowToTop();
rpt_cpu_category->SetActiveWindow();
rpt_cpu_category->UpdateWindow();
"RPT_CPU_CATEGORY" is the name of the dialog resource.
The last 3 lines are redundant as they seem to have no effect, they were just my latest effort to try and get the dlg to take the focus. I have also tried using setfocus() (no luck).

A string literal is certainly NOT suitable to select a dialog resource.
[later correction]
A string literal is indeed suitable as a dialog resource.
[/later correction]
Why do you need to give it a dialog resource in the first place? What did you do to the perfectly working class the class wizard made for you?
You should have one class for every dialog resource you designed, and the connection between resource and class is internal to that class (look for IDD in the dialog-class if you are interested).
