Try getting more RAM. At 512 MB, the emulator never crashed on my laptop (Win 2K). Also, you can try reinstalling the 2002 SDK. If everything fails (a very decent probability), consider buying a real device. I did that...

Thanks! I've got a real device. I just thought that it would be quicker to emulate than to develop on the "real thing". Programs created and downloaded to the PocketPC i've got works just fine Smile | :)

Again, thank you!

Dear Friends,

Does anybody know how to set break point on a shared
memory location using Embedded VC++ 4.0 debugger.

I have a dll[C language] that allocates and uses shared
memory. I want to set break point on some memory locations
of allocated shared memory.

When set memory break point in debugger currently it is
not functioning. Execution stops there and i can not
proceed further except closing Debugger.

Thanks in advance,

How to get Window Rect coordinates wrt to its parent window rect coordinates.

Dear Friends,

Does anybody know how to get child Window Rect coordinates wrt to parent window Rect coordinates. [Something similar to GetRectInContainer()]. I want in SDK rather than in MFC.

Thanks in advance,
subramjobmail.

Re: How to get Window Rect coordinates wrt to its parent window rect coordinates.

Do you mean you want the position of your client window inside the parent window?

RECT rtClient;
// Get the position of the client in screen coordinates
GetWindowRect(hClientWnd, &rtClient);
// Converts the screen coordinates to client coordinates
ScreenToClient(hClientWnd, (LPPOINT) &rtClient.left);
ScreenToClient(hClientWnd, (LPPOINT) &rtClient.right);

You understanding is correct but the code block which you have given
will give only wrt to screen point.

But i want wrt to parent window RECT of hClientWnd. It should proper
values (-ve values) if scrolled [partially visible]

Something like how GetRectInContainer() gives in OCX wrt to IE

Something like this?

HWND hWndParent = ... // Handle to the parent window
HWND hWndChild  = ... // Handle to the child window

ASSERT(hWndParent);
ASSERT(hWndChild);

RECT rt;
::GetWindowRect(hWndChild, &rt);
::MapWindowPoints(HWND_DESKTOP, hWndParent, (LPPOINT) &rt, 2);

Vectors in windows CE

Okay, I finally found enough time to try coding for these pocket pc devices. But I'm a "lazy" coder and I want to do things the easy way. Meaning that I use all the ready standard components found. So of course I want to user vectors to hold data, but what - I can't find them WTF | :WTF:

.

So there are no vectors in CE, or am I wrong here (I hope so). So the question is, what is the thing to use, when you would normally use vectors?

You can use STLport in CE. Check these links:

There are also some container classes inside the MFC (also in the CE version).
Just take a look at the following classes: CArray, CList, CTypedPtrArray, ...

I hope this will help you!

Thank you. These classes are just what I was looking for... Well they aren't vectors, but they're close enough Wink | ;)

STLPort also looked interesting, so thanks for the links concerning that too...

Odd behaviour inserting into Sql CE

freshthinking4-Sep-03 22:25

4-Sep-03 22:25

I have a relation called Correspondence of the following format:

corrId int identity(1, 1) primary key
type varchar(50)
cwith varchar(50)
isInternal smallint(2)
rowguid uniqueidentifier

the rowguid attribute was added by sql server when setting
up merge replication.

On the CE application I am trying to insert a row into the table and then pull the corrId back out using @@IDENTITY. Strangely when I try and insert I get the following error:

HR: 800040E2F
Native: 25016
Message: A duplicate value cannot be inserted into a
unique index [,,,,,]
Source: Microsoft SQL Server 2000 Windows CE Edition
Parameter 1: 0
Parameter 2: 0
Parameter 3: 0
Parameter 4:
Parameter 5:
Parameter 6:

I could understand the error if the corrId wasn't being incremented by 1 each time (& it didn't have the uniqueidentifier attribute). The question is what am I missing that's causing the problem?

Thanks in advance.

Docs say:

"Ensure that a replication publication is configured to manage identity columns for a table(s) in the publication."

Is your publication correctly configured? By the way, what layer are you using to access the DB: ADO oe OLE DB?

João Paulo

If you mean did i let it use "Mark identity columns with the NOT FOR Replication" thing, i let enterprised manager sort it out. I have no problem inserting into other tables that have identity attributes, which is why i am finding this very odd behaviour.

I am using OLE DB. I haven't use Sql CE before and based my code on an example from the MSDN site, which used OLE DB. ACctually in the connection string for the SqlCeConnection object when i stated a 'Provider' initially it gave errors saying invalid token or something along those lines, so i removed it and specified the 'Data Source' only, and it works. I'm not entirely sure what it uses in that case. However def OLE DB for the replication.

Coudln't work out what was causing it, so I changed the format of the table to remove the identity attreibute, all working now. thanks.
