One suggestion which I find is needed when moving between Win98 and NT4 is to do rebuild all the files - go to the Build menu, then Rebuld all.
This is because the precompiled headrs are differnt between Win98 and NT 4.
Good luck

Hey !
Thanks for your answer, but I rebuild the source for more than one times on the new platform. And I didn't use precompiled headers, allways I compiled the complete project.
Any other ideas ?

Hi.
I have a problem with my SingleDocTemplate applicaation.
When I quit, I have the following message in the debug window:
Warning: destroying CSingleDocTemplate with live document.
This causes a memory leak with my document.
I tried to solve it for 3 days, but can't make it work.
Please help me.

BoundsChecker is reporting the following code as a memory leak:
void foo()
{
_bstr_t bstrA;
_bstr_t bstrB;
bstrA = "Fred";
bstrB = "Wilma";
bstrB = bstrA.copy(); // this causes the leak
// this fixes the leak - bstrB = bstrA
}
At first I thought it was a leak, then I decided it wasn't, now I can't decide! Is it, or isn't it

Yes, that will leak. "copy" will create a copy and then the assignment will create another copy since it can not assume that the original is free for ownership.
bstrB = bstrA;
bstrB .Attach (bstrA .copy ());
bstrB = bstrA .copy (false);
These should all work just fine. But I don't do a lot of _bstr_t work.

You can see how to do this in MSDN topic CWinApp::GetPrinterDeviceDefaults.

Hi,
In a dialog based application, I have three resizable windows.
The first one is used for a 2D curve and it can be resized in both of x-axis and y-axis directions. The second window (image container) only can be resized at x-axis and the third window only can be resized in y-axis direction. This looks like follows:
********************
* * *
* curve (1) *(3) *
* * *
* * *
********************
* image (2) *
* *
********************
Also I can change the size of the bmp image by using StretchBlt
function.
Now, I hope that the length of the image (not the length of the second window) should follows the length of the first window in the case of resizable of whole window.
How should i do this? How can i get the length of the first window?
Thanks in advance!

sorry, the window changed when post above message.
It looks like:

111111111111133333
111111111111133333

It has to do with COM and Automation. It is basically just a wrapper for any possible type of data you can transmit through Automation. I think it was designed like that to work with Visual Basic  better...

I want to make a serial port communication program. I define a STRUCT variable
struct _COMM_PACK
{
char sID[PACK_ID_LEN];
BYTE cCmdCode;
UINT nVerifySum;
int nDataLen;
BYTE cData[MAX_DATA_LEN];
}aSendPack;
and want to send 'aSendPack'in the Mscomm control-comm like:
comm.SetOutput(aSendPack);
but the SetOutput need a VARIANT variable
how can I do that?
thanx!

Could anyone tell me, where does windows store its default checkbox and radio images?
I've found some odd resources in ctl3d32.dll (these seem to be pre-win32), some in ctl32v2.dll (this even is not a valid PE ) and some in mfc42.dll. But 1st) i cant believe that non-mfc progs use this library, and 2nd) it hardly can believe that win produce grayed copies of these (for pressed-and-holding-buttons) on the fly.
The main purpose of this quest is creation of owner-drawn button, but I dont want to follow Davide Pizzolato's footsteps and include images as resources in built project like he did in his CxShadeButton.

Here is my code :-
void CReportView::OnInitialUpdate()
{
Navigate2(_T("about:blank"),NULL,NULL);
IHTMLDocument2 *pDoc=(IHTMLDocument2 *)GetHtmlDocument();
if(!pDoc)
{
return;
}
HRESULT hr;
SAFEARRAY* psa = SafeArrayCreateVector(VT_VARIANT, 0, 1);
VARIANT *param;
MessageBox("L");
BSTR bsData = m_html.AllocSysString();
hr = SafeArrayAccessData(psa, (LPVOID*)¶m);
param->vt = VT_BSTR;
param->bstrVal = bsData;
hr = pDoc->write(psa);
hr = pDoc->close();
SysFreeString(bsData);
SafeArrayDestroy(psa);
}
You can see the MessageBox call there. If the MessageBox is there, it works right and shows the html rendering of the source contained in m_html which is a CString. If I remove the MessageBox, the html comes rightly for about 0.005 seconds [approximate guess] and then it becomes blank

Okay, this is a sorta make-shift work-around
void CReportView::OnInitialUpdate()
{
CHtmlView::OnInitialUpdate();
Navigate2(_T("about:blank"),NULL,NULL);
}
That's all
Now I have my own
void CReportView::RenderView()
{
...
...
}
This has sorta solved the issue. I call RenderView when I want to change the contents

Hai,

When this happens, close VC and delete project files *.aps, *.ncb, *.opt. Open project again - it should work properly.

Don't need to close the project and do those stuff, all you need to do are the following:
1, Use "file view" to open the header file of that "disappeared" class.
2, Intentionally produce at least one error in that header file, for example, type a few dummy characters somewhere. Build your project, and of course you'll get some compiler errors, good!
3, Clean the error(Remove those dummy characters you typed), rebuild your project again.
That's it. Now go to "class view" and you'll see that class appears again.
