Hello.
Does MS Access support BatchUpdates?
I have a project in which im using following code but it gives me an error when there is
more than 2 records in the recordset which have been changed

IDispatch error # 3156 :Number of rows with pending changes exceeds the limit.

<br />
//////////<br />
		_variant_t	v(m_pProject->m_ptrConnection.GetInterfacePtr());<br />
		<br />
		//	Open recordset<br />
		m_pRstBugs->CursorType = adOpenKeyset;<br />
      		m_pRstBugs->LockType = adLockBatchOptimistic;<br />
		m_pRstBugs->Open((LPCTSTR)ProjectName, v,<br />
			adOpenKeyset,adLockBatchOptimistic,adCmdTableDirect);<br />
		<br />
		if (m_pRstBugs->Supports(adIndex) && m_pRstBugs->Supports(adSeek))<br />
		{<br />
			// im making an index<br />
			m_pRstBugs->Index = DBtags::m_sProjectIndexName;<br />
		}<br />
		// ...<br />
		<br />
		<br />
		// here is the problem: Error -> "Number of rows with pending changes exceeds the limit."<br />
		m_pRstBugs->MoveFirst();<br />
		while(!m_pRstBugs->adoEOF)<br />
		{<br />
			_variant_t	x("test");<br />
			m_pRstBugs->Fields->Item["description"]->Value = x;<br />
			m_pRstBugs->MoveNext();<br />
		}<br />
		m_pRstBugs->UpdateBatch(adAffectAll);<br />
		//	end test<br />
		<br />

I'm not sure how many changes are supported, but I think(!) the Jet Database Engine only supports 1. You might want to check out the "Maximum Pending Rows" property of your RecordSet object before making any changes.

The article for the property is on MSDN at

Does anybody know how I would enumerate LAN connections and disconnect them. I know you can do this with the RAS API for dial-up connections but I am not sure if it works with LAN connection

Thanks

CStdioFile and Seek-Method

tabor2514-Apr-03 3:09

Hello,

i am using a CStdioFile object to read in a text-file. On some positions within the file i have to seek. I do it like this:

CString line;
CStdioFile file;
...

/* Read a few lines */
while (condition) {
file.ReadString(line)
/* do something with line */
}

/* Save current start-position for new line */
DWORD pos = file.GetPosition();

/* Read a few lines */
while (condition) {
file.ReadString(line)
/* do something with line */
}

/* Go back to saved position */
file.Seek(pos,CFile::begin);

Positioning the file-pointer by using the seek-method works only correct, if every line has a 0A 0D at the end. Now i have to parse a file that only has 0A at the end and the seek-method fails. It sets the file-pointer to the middle of a line and not to the beginning of the expected line. Please help!

Best regards

Do you know whether ReadString() appends or overwrite previous data in a CString object?

Hello Kuphryn,

ReadString() overwrites the previous data in the Cstring object.

How do you move a window without showing it?

Abin14-Apr-03 3:04

Hi, I have a whindow which is currently minimized, now for some particular reason I must set it to be a foreground window for a short moment, but I do not want the user to see it. So the best way to do so, I guess, is to restore the window then immediately move it off screen(e.g., call "::MoveWindow" and give it a CRect(-999, -999, 100, 100), or something like that).

Now the problem is that, since calling "::MoveWindow" while the window is minimized has NOT effect, I must first restore the window by calling "ShowWindow(hwnd, SW_RESTORE)", at that time, before it gets moved off screen, the window displays on screen for one second or two, and that will annoy my user.

So, is there anyway I can move a previously minimized window off screen without letting it show on the visible screen area at all? Thanks.

And the following :

Hide -> Restore -> Move -> Show ? Cn you hide it while it is minimized ?

~RaGE();

won't work

Abin14-Apr-03 13:36

Since SW_RESTORE will display the window regardless of its previous state.

Hi !

I have programmed a visual c++ add-in, which runs fine on all our visual c++'s but one, which throws the error : add-in cannot be registered because DllRegisterServer() fails. Add-in will not be loaded again. (Merely translated from German Blush | :O

).

There is no memory error, registry can be accessed, so any idea of what could be the problem ?

Platform is WinNT 4.0 SP 5.0, Visual C++ 6.0.

Can anyone recommend a good package of charting components? I've downloaded a demo of GigaSoft ProEssentials and that's the sort of thing I'm looking for. I don't know what else is out there and I'd like to know how it compares with other packages. I'm more interested in scientific applications, including plotting in real time as data is collected, than simple pie charts, etc. Thanks for your help.

It works ...

but you have to change the autosize-function ... the actual autosize calculates a height for only one line of text !!!

Look at http://www.codeproject.com/miscctrl/gridctrl.asp ...

Search for multi-line, word-wrap etc.

LoadImage is the SDK command you want.

hBmp = (HBITMAP)::LoadImage (NULL, "c:\test.bmp", IMAGE_BITMAP, 0,0, LR_LOADFROMFILE);
