Hi ,
i have a Dialog box which has a combobox and which on clicking a button retrieves the index of the selected item and stores in a integer variable, now how do I access this variable from another dialog box?..
for example:
void CMyprogDlg::OnOK()
{
int com = m_com1.GetCurSel();
}
How do I access the integer variable 'com'from another dialog box? It would be great if someone sends some example source codes.
Thanks,
Deepak Samuel

You can't. It's a local variable.
You have to expose the value in the dialog class, globally or send the value via a message to another thread/window.
Since you are setting it with OnOK, the traditional way would be to create a member in CMyprogDlg. The function that created the dialog would then read the value if the dialog returned successfully. It would then either store it its own data member or locally, if the new dialog would be created right away.

'set vdo = srvobj.getobject("IIsFtpVirtualDir", "mydir")

I defined 2 Document Templates in my MDI App......
But I dont know how to call MDIChildWnd of CLogin (or MDIChildWnd of CChangePassword)
I mean:
When user select menu "Login" (ID_LOGIN) => Show Login MDIChildWindow
When user select menu "Change Password" (ID_CHANGE_PASSWORD) => Show Password MDIChildWindow
Could you help me ?
And ...... Login Window, ChangePassword Window have only one instance in my MDI app .......... so that I think I don't need use
Document Template. Is that right ?
Important: my MDI Child Windows must be dialog-base window(I will design controls in these dialogs by Dialog Editor)
please help me .......and a little sample code if possible (I have read MSDN but dont find what I need)
Thank a lot!![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

hi,
When I compile the following code:
DISPID dispid;
DISPPARAMS dispParams;
OLECHAR FAR* szMember =_T("updateList");
...
hresult = lpList->GetIDsOfNames(IID_NULL, &szMember,1,LOCALE_USER_DEFAULT, &dispid); //IHTMLSelectElement *lpList=NULL; lpList is initialized before
I always get this error:
error C2440: 'initializing' : cannot convert from 'char [11]' to 'unsigned short *'
Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
I can't get any answer from Microsoft, please help solve the problem!!!
Thx.
Alan

This is just an offhand guess
stick this at the top of the cpp file
#include <atlconv.h>
Here is the conversion
DISPID dispid;
DISPPARAMS dispParams;
char* tmpstr =_T("updateList");
USES_CONVERSION;
LPOLESTR szMember = A2OLE(tmpstr);
hresult = lpList->GetIDsOfNames(IID_NULL, &szMember,1,LOCALE_USER_DEFAULT, &dispid); //IHTMLSelectElement
|

It doesn't work, I got the same error.
Do u know other way to solve it?
Thanks

"OLECHAR FAR* szMember =_T("updateList");"
how could you have possibly got the same error, the line above was the line that caused the error, and in the code I posted, that whole line is gone. OLECHAR FAR* wasn't even the right datatype for the param.
Maybe your object file is old, try rebuild all.
Here is the conversion again.

To declare a wide char constant, use L"updateList" ( _T("foo") evaluates to L"foo" in unicode, and "foo" in MBCS/ANSI builds)

Hi, all
I was wondering how to lock (not disable) an edit box during runtime, so the content (the text) in the control can still be selected but not modified/edited. I am using regular Windows API (no MFC) and I also want to be able to unlock the edit box.
Thanks in advance

if you want to do this easily, you'll probably want to use CRichEditCtrl with the read only property enabled instead of CEdit
|
|
|
|
|
|
doesn't setting read only on an Edit gray the box by default? If so, and I can remember it doing that, you'd have to subclass and override.
That's why I suggested the rich edit instead.
|
|
|
|
|
yes it does - (I thought that would be ok with the asker)
However, there's a message you can override in the dialog to proivde a different background brush.

Either use the ES_READONLY style when you create it, or the EM_SETREADONLY message (CEdit::SetReadOnly if you use MFC) at any time after creatign the control

As others have mentioned, you use the EM_SETREADONLY message. However, this will cause the edit box to be grayed out. You can still select the text, copy it, etc..
If you want the control to look like a normal edit control, but be read-only, then you need to catch WM_CONTROLCOLOR and look for the controls window handle and return a brush that's the same as the users color preferences.
I'd advise against that, though. It confuses users when a control looks editable, but really isn't.

I'm not new to programming but new to progress bars and I would like to know how to use it (using the default class for it) not some other class. I would appreciate it if anyone replied

Do you use MFC oder plain API? I case of MFC:
Drag a progress bar from the controls toolsbot to your dialog to place it there. Next, create a variable for the CProgressCtrl e.g. using the Class Wizard.
If your variable is named e.g. "m_ctlProgress", you need to set some attributes, you can do this in OnInitDialog():
m_ctlProgress.SetRange(0, 100)
m_ctlProgress.SetRange(1, 255)
you can then set the postion of the blue bar with
m_ctlProgress.SetPos(128);
see MSDN for more information.

Can anyone tell me how to save from a dialog not a SDI or MDI but Dialog.
You know like putting a variable into it or several into a specified external file and opening it. Need Details since I'm kinda new to saving/serializing

//Serialize Save Int
CFileException e;
CFile theFile;
if (!(theFile.Open(filename, CFile::modeWrite | CFile::modeCreate, &e))) { TRACE("can not open file for writing"); return; }
CArchive ar(&theFile, CArchive::store);
int p = 1
ar << p;
//Serialize Load Int
CFileException e;
CFile theFile;
if (!(theFile.Open(filename, CFile::modeRead, &e))) { TRACE("can not open file for reading"); return; }
CArchive ar(&theFile, CArchive::load);
int num;
ar >> num;
Repeat this for everything/datatypes you want to serialize. Can't remember whether you have to close the file after or if MFC takes care of that for you when you serialize, so I left it off.

The destructor of CFile closes it for you! If you create the CFile object on the heap, you have to close it manually.

Is hyperthreading anything to get excited about.
XP is meant to support it, so I was wondering if in future apps that I make that are CPU intensive should I consider an architecture that can be modified to use it?
If so, I guess I'm on another learning curve.

AFAIK, from an application's point of view, a HT CPU looks the same as two non-HT CPUs. So you can just use your existing multi-threaded programming talents.
