This i know is gonna be simple but it is foxing me.
I have a dialog based application. On the main form it minimizes and maximises correctly, if i open a pop-up dialog from the main dialog then minimize the pop-up box it minimizes to the corner of the desktop not the taskbar, leaving the parent window showing (disabled) on the desktop.
I have tried <popupdialog>->SetParent(this) before calling DoModal but this creates an exception. Has anybody any ideas what i am doing wrong.
Thanks
Matt

You should pass 'this' into the dialog when you create it, thus making your main dialog the parent.

Let's say that I've developed a COM-inprocess STA server.
QUESTION 1:
A c++ client can specify STA client thread by:
CoInitialize(NULL, COINIT_APARTMENTTHREADED);
How can you do this from an ASP application? For instance, you cant specify client threading model with CreateObject:
<% Set Session("ad") = Server.CreateObject("MSWC.AdRotator")%>
This will store the com server in session scope. But threading model?
QUESTION 2:
I am writing a backend server component that generate a SQL "statement" based based on input ASP. What's the best threading model for this situation? Note that this component is NOT responsible for database access. It simply get input from ASP and pass back a string to ASP
Thanks

You can't. The thread model will follow that of the server component.

Try not to do this. I don't know for this specific component, but storing an STA component on the Session or Application objects will impact your server performance and scalability very soon. The ASP engine has only one STA thread for creating and executing components. This means it will create a bottleneck for your pages and can hang your entire server.

Thanks, reading up on MSDN. They suggest Both or Apartment. And recommended NoEntry and Free.
So, look like MTA-Both-inprocess server will be the solution.

Thanks, that's very helpful. Didnt see this in any doc yet...

Hello,
i have an MDIChildWnd with StatusBar and Sizegripper.
I now want to change this resizable window into a non-resiable one, and vice versa. I removed WS_THICKFRAME from frame window. The window size is now fixed but the Statusbar don't get updated and the sizegipper is still shown. I tried a lot (e.g. invalidate, setwindowpos with SWP_FRAMECHANGE) to get it repainted correctly but it only works if i call the function twice (from menu or button).
Has anyone an idea how to change this dynamically.
Any help would be great

Hi all, I've been sent messages about my question, I did everything they told me but there's still something I'm doing wrong.I'll tell you with details...: I'm doing a Win32 program. My program is Dialog based and i've put some controls on it. The problem is that i've put a notified picture control and I can't change the mouse pointer, everytime is moving over that control, from Arrow to Hand???....HEEELLLPPP!!!

Did you try subclassing the window like I told you. That should definitely work. Also try chaning the cursor to a cross for example IDC_CROSS. The hand does not work with all windows version. VC 6.0 doesn't even recognize IDC_HAND when I try to compile it so I had to download a cursor from the internet that looks like a hand and load it in as a resource. If you are still stuck you can e-mail me your code, I'll put in the necessary code, comment it, and mail it back to you.

i sent you an email but i forgot to tell you that i didn't subclass it... Oopsss Sorry!!!

Hi!
I have created a simple SDI application with with a CommandBand on top of my application window.
I have created the CommandBand like in the tutorial Using Windows CE CommandBands in an MFC based Application
by Bruce Hearder.
The problem is that when I am opening a dialog, like the "Open File..." dialog and invoke some of the SIP elements, like the Keyboard Input and press ENTER to close the dialog, after the dialog has closed, the CommandBand will be not visible! It looks like the view does resized to the whole area and the CommandBand will be moved outside the screen. It is only when I am opening a dialog and invoke a SIP element and close the dialog (during the dialog is closing the SIP Keyboard is visible).
How can I fix that? Please help!

I have written an application that sticks to a target application, I've done this by writing a dll that implements a windows hook (so it gets put into the target app's process space), then i've subclassed the windows proc. In my new windows proc i send the winodows move messages to my application.
Anyway all this works fine on windows XP, 2000, NT but i'm having problems on windows 98.
The move messages get passed fine, but when i minimize the application, it crashes. If I rerun the application it all works fine, I can't really put my finger on what the problem could be ?
Has anyone else out there had any experiance in this field ?

He's probably aware that there is a connection between CP and CG, being that Chris escaped CG to start CP.

Chris and others helped out @ CodeGuru, which was started by Zafir. CodeGuru was eventually sold, causing it (imho) to decline into a poorly maintained state. Chris saw the opportunity to do a (much) better job and did it. Some of us who helped out @ CG continued to do the same @ CP.

I was seeking the gethotspot api few months ago and never found it. it should be in the CURSORINFO struct but it isn't.
If someone know a way to get this hot spot i'm very interested in too. I need it to remove a define in my code.

Hi,
I want to create an application which gives a certain amt of the system disk space for global sharing. Is there any mechanism for that? How can I do that? Also other client machines should be able to store their files, if required, to this shared storage space and retrieve it later.
How can I restrict the shared space to a fixed amt?
Kindly help.
Regards,

I would like to create a class much like a CListCtrl for file selection on a Pocket PC. I don't like the file dialog that's ready-to-use.
BUT, I'd like it to have a simple interface. So my thought was that I could use protected inheritance to derive a class (CFileListCtrl) from CListCtrl, so users of my custom control wouldn't be able to mess with any CListCtrl methods that could "mess up" my custom control.
Does this seem like a reasonable approach? Do any of you know if I have to do anything other than set up my custom methods (which will then use the methods of CListCtrl), and registering the custom control class as per one of the tutorials on this site on custom controls?
I'd appreciate any input. Thanks.

Hey fellas,
Right now I am pretty much stuck at a point  I am modifying a device driver and well I don't really have much prior experience doing such stuff. For debugging reasons I need to write some data to a disk file. For this purpose I am using the following code :-
NTSTATUS Status;
LARGE_INTEGER ByteOffset;
IO_STATUS_BLOCK IoStatusBlock;
OBJECT_ATTRIBUTES InitializedAttributes;
UNICODE_STRING ustr;
HANDLE handle;
WCHAR fname[] = L"\\??\\D:\\Output.txt";
RtlInitUnicodeString(&ustr,fname);
InitializeObjectAttributes(&InitializedAttributes,&ustr,0, 0, NULL);
Status = ZwCreateFile(
&handle,GENERIC_WRITE|SYNCHRONIZE,
&InitializedAttributes,
&IoStatusBlock,
0,FILE_ATTRIBUTE_NORMAL,
0, FILE_OVERWRITE_IF, FILE_NON_DIRECTORY_FILE|
FILE_WRITE_THROUGH|
FILE_SYNCHRONOUS_IO_ALERT,
NULL,0);
ByteOffset.QuadPart = 0;
ZwWriteFile(handle,NULL,NULL,NULL,&IoStatusBlock,
data,512,NULL,NULL);
ZwClose(handle);
My problem is that the file is not getting created at all! Can anyone tell me what I doing wrong here?
