eh, u see, i've already been there, a FEW times lol. Booo @ M$ they used to give it for download for free now u have to freckin order it. I cliked order once and it said 0$ so i thought hey this might not be so bad afterall, but then i got to checkout and turns out i would need to pay 25$ for shipping costs since i'm in Belgium.
So i ran a search for an alternative (read 'illegal') download location of the Win98 DDK. And i found one! like the third search result or something lead me to a non-MS page and it had a download link on it directly to the MS server where u could STILL download the Win98 DDK!!! I mean.. how freaky is that, they take it off and make u order a CD with the new DDK but they just leave the file there, handy..
Anyways, so i downloaded it, and when i installed it said it was for Driver development with Win98 and Win2000 (and NT4). But if its compatible with Win2000, isn't it compatible with XP too?? or is there a difference between XP and 2000 i'm missing...

WTF | :WTF:

Thanks!

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.

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]

Error on OLECHAR FAR*

Small Rat27-Jul-03 5:49

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.

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.

stick this at the top of the cpp file
#include <atlconv.h>

DISPID dispid;
DISPPARAMS dispParams;
char* tmpstr =_T("updateList");
USES_CONVERSION;

hresult = lpList->GetIDsOfNames(IID_NULL, &szMember,1,LOCALE_USER_DEFAULT, &dispid); //IHTMLSelectElement

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

How to lock an edit box?

Aidman27-Jul-03 5:26

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 Smile | :)

if you want to do this easily, you'll probably want to use CRichEditCtrl with the read only property enabled instead of CEdit

peterchen27-Jul-03 8:32

You can do that to an Edit, too...

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.

peterchen27-Jul-03 9:45

27-Jul-03 9:45

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
