I have an MDI application and serializing it as text. The problem is, when I open the saved files, there are "Entry Root" word and other
kind of texts. What should I do to save as pure text?

What does the Serialize() method currently look like?

Hi, I'm using C++ to create an extended sotred procedure that calls a manged DLL that calls a web services
When I come to translating the stream of parameters passed from SQL into variables I get an access violation error.
can anyone see why (I am not a C/C++ programmer, so I'm sorta out on a wing here)
srv_paraminfo(srvproc, 3, &bType, &uMaxLen, &uLen, NULL, &bNull);
BYTE* Data = new BYTE[uLen];
memset(Data, '\0', uLen);
srv_paraminfo(srvproc, 3, &bType, &uMaxLen, &uLen, Data, &bNull);
char * temp;
temp = (char*)Data;
_bstr_t DateTendered;
DateTendered=_bstr_t::_bstr_t(temp); <- this line causes error
any help would be great

I don't know too much about _bstr_t, but maybe it has something to do with the copy constructor. Try changing this:
_bstr_t DateTendered;
DateTendered=_bstr_t::_bstr_t(temp);
to this:
_bstr_t DateTendered(temp);
I don't know if it will help or not, just a possibility, the rest of the stuff looks ok to me, but it is only 6:45 and I'm half awake

Okay, I'm having this problem and don't want to have to do too much in order to get it to work properly. I have a wizard set up using CPropertySheet. There is a property page that is shown that begins processing information and displaying its progress on the shown CPropertyPage, but when the user presses cancel I want the overrided CPropertyPage method OnCancel to be called so it can tell the CPropertySheet parent to switch to the appropriate error page (lets say when its processing and the user presses cancel, I want it to kill the thread processing the data (got it to do that), and switch pages automatically telling the user that the processing wasn't completed because it was canceled). I know that when I click the "Cancel" button on the sheet that it fires the OnCancel method, but even if I prevent the following statement from executing, it still closes the window:
CPropertyPage::OnCancel();
How do I stop the sheet window from closing when I press Cancel and do what I tell it in my overrided OnCancel method?

Is it possible to let a user draw his own button at runtime? I mean to say,that the button size be varied with its position also at runtime.
Actually,my project work needs to make a toolbar analogous to "Micrsoft Paint"'s toolbar in which there will be button tool which a user can use to make a button in his workplace.It will be more suitable if the button is circular rather than rectangular as seen normally in VC++ .
|

Yes, it is possible. If you want to draw your own type of button that's circular that's possible too. Don't expect code here though, that's pretty much beyond the scope of a forum thread, just read up on owner draw buttons for the circular button question. For resizing the button, you will need to just code some way for the user to resize it, put it in some custom view or something and handle the mouse events, you can call MoveWindow() to resize the button.

In Win32 is there an easy way to query the top n windows on the screen by Z-Order and get their handles?

Have you tried using EnumWindows()? I can't remember off the top of my head whether or not it goes by Z Order, but I think it may.

Try Combination of FindWindow and FindWindowEx.
here is small piece of code,please Check Is it suit your requirements.
BOOL NMPEnumWindows(CStringArray *arWindowsName,CPtrArray *arhWnd)
{
<font color=#008000>
HWND hWnd,hWnd1=NULL;
CString Str;
char lpString[201];
<font color=#008000>
hWnd=::GetDesktopWindow();
<font color=#008000>
do
{
hWnd1=::FindWindowEx(hWnd,hWnd1,NULL,NULL);
<font color=#008000>
::GetWindowText(hWnd1,lpString,200);
Str.Format("%s",lpString);
<font color=#008000>
</font>
If((::IsWindowVisible(hWnd1)==TRUE)&&(Str!=""))
{
arhWnd->Add((HWND)hWnd1);
arWindowsName->Add(Str);
}
}while(hWnd1!=NULL);
return TRUE;
}

I am writting a C++ application.
There is a long running processing in the application. While it is doing something, if I move any "windows" on top of the application. the applicaiton become "blank" -- no message shows on UI. How can I refresh the UI of application?
|

You need to put your "something" in a separate thread so that the main thread can still process paint messages.

"a long running processing" refer to in a while loop. the interation can be from 0 to 10K. I found whenever the application is inside that code section and if I move another windows on top of the application, then the UI is wiped out.
|
|

|
|
You can try something like this....
for (int i=0; i

I have a program that brings up two dialog windows, I would like them to overlap and appear in a tab like manner much like an index, so when you would click on the tab for the window to appear. My question is how to accomplish this. Thanx in advance, and forgive this if it seems elementary.

Why not just use a real tabbed dialog rather than a faux one?

Hey. I finally figured out a way to put a checkbox on top of a button. In the toolbox, select Owner Draw to be true. But now if I create a variable associated with the button (later on in the application i have to hide the button) it causes the program to crash.
Any of you know the proper way to prevent buttons with Owner Draw set to true to prevent from crashing.
thanks,
-akbar

I found a way around it
GetDlgItem(BTN_NAME)->ShowWindow(0);
but I still need a skinnable button that I can lay the checkbox control ontop of it :/

Hi - I'm looking for a good description or sample code for how to get data from a USB device (say a still image camera) into a visual c++ app. I've seen hints about using TWAIN, or using plain old file io, but not enough detail anywhere to Make It So. Plenty about driver development, but nothing about app-level. Any links or suggestions appreciated.
- Thanks, Barney
