I get the date from my CMonthCalCtrl like this:
CTime CurrentCDate;
CString CurrentSelectedDate;
//Get the currentselected date
KalenderControl2.GetCurSel(CurrentCDate);
CurrentSelectedDate.Format(_T("%02d / %02d / %02d"),CurrentCDate.GetDay(),CurrentCDate.GetMonth(),CurrentCDate.GetYear());
//Put it in a box
SetDlgItemText(IDC_CURRDATE2,CurrentSelectedDate);
This gives me a f***ed up date, days +13 (in win 2000) and days +8, months +3 in win95/98. I need help on this please, what am I doing wrong that the output is wrong?
Thanks in advance,
Tom Cornille

Hi,
how can i get the active view (or the active document) from a non-modal dialog?
I have tried
CFrameWnd *pFrame=GetParentFrame();
CDocument *pDoc=pFrame->GetActiveDocument();
and
CView *pView=pFrame->GetActiveView();
but both, GetActiveDocument() and GetActiveView() return NULL although there was a document (and therefore a few, too) created.
I'm working with MDI docs/views.
Thanks for your help!
Chris.

Instead of
CFrameWnd* pFrame = GetParentFrame();
try
CFrameWnd* pFrame = (CFrameWnd*) AfxGetMainWnd();
|
|
|
|
|
I just tried that, but i still get NULL for pFrame->GetActiveView() and GetActiveDocument()!??!
|
|
|

From MSDN:
[CFrameWnd::GetActiveView]
"This function returns NULL when called for an MDI main frame window (CMDIFrameWnd). In an MDI application, the MDI main frame window does not have a view associated with it. Instead, each individual child window (CMDIChildWnd) has one or more associated views. The active view in an MDI application can be obtained by first finding the active MDI child window and then finding the active view for that child window."
There is also an example of code.
Cheers,
Paolo.

Hello All,
After I do a FindItem on a CListCtrl, It returns an int. How do I use this int to scroll and hightlight the row to make is visible to the user?
There is a Scroll method but it take a CSize, Do I have to convert the int to CSize?
Thanks,
Tony

Call CListCtrl::EnsureVisible() to scroll a row into view.

Hi,
I would like to communicate with the serial port in my app. I think the best way is to create a worker thread accessing the serial port and filling in a CString object (something like a buffer) with the incoming characters. It must also be possible to send chars to the connected hw.
I was looking for a class implementing serial port accesses and I got PJNaughter's one. It seems to be quite well implemented but I cannot figure out how to use it in such a working thread. Is it possible to trap messages? How can I now when I have to read on the serial port? Must it be a forever loop or can it be implemented within the Windows Messages Routing?
Please help me.

Hi,
I don't know exactly how the class looks like but you must have some function to notify you when an event occured.
Should be somenthing like "WaitForEvent" with some parameters (event mask and timeout).
You must wait until an event like CHAR_RECEIVED occures or timeout expires .. Something like that.
General flow is something like this:
Without handshake :
- if you don't locate this kind of function to do the job for you try this :
read the port with timeout and if char received is TIMEOU_CHAR or something like this -> you didn't receive something and try again, when first valid char occures you start to construct your message. Use this on thread and be carefully with your time out values.You should have some predifined types for TIMEOUT_CHAR.
To send is much more easier, just send it.
with handshake :
- RTS/CTS, DTR/DTS or XON/XOFF you should read the protocols first and you should find functions to acces this signals from comm port.
But the genereal flow is the same. This signals helps you to know when you can send something via serial port (if device is occupied and cannot receive will raise the CTS signal ..... ).
i hope it's helpfull for you.

How can I open an existing WAB file and create a new WAB file?

I realize that this isn't exactly on subject, but I didn't see a database forum. SQL Server 2000 is supposed to have something called Federated Databases which is supposed to spread a database out over several machines, sort of like drive striping. The number of machines is supposed to be variable on setup, and reconfigurable later. Oracle has something similar called Distributed Access, but it is supposed to work differently. Does anyone have any information about a comparison between the two and which is better for what type of operations?? Thanks for your time.

Hi, I am in a problem:
An application works just fine, but:
As soon as I extract my resources into a resource-only DLL only the dialogs with standard-controls continue to load. (Therefore it is clear, that at least the app finds its resource-DLL.)
Every dialog containing CUSTOM CONTROLS fail to load:
In CDialog::DoModal() the call to CreateDlgIndirect() returns FALSE, as a result the creation is simply stopped.
I tried this with several examples from this site, the behaviour is the same...
I assume that somehow the app must get to know there are custom controls in the DLL, but how?
Any hints??
Greetings, Martin

Did you call AfxSetResourceHandle() to tell the framework you are using an external resource dll?
If not, load the dll with LoadLibrary() and then pass the handle to AfxSetResourceHandle() in your InitInstance override.
If you are already doing it, I don't know what's the problem.
Cheers,
Paolo.

Hello Paolo,
thank you for your time.
I got this code from MSDN, which should do the job:
m_hInstDLL = ::LoadLibrary("ExtRes.dll");
if ( !m_hInstDLL )
{
return FALSE; // failed to load the localized resources
}
else
{
AfxSetResourceHandle(m_hInstDLL); // get resources from the DLL
}
As I wrote, it works with simple elements, it only fails with custom controls and ActiveX-controls.
Must I tell the DLL that it has to use these? Or the App, that the DLL uses it? HOW???
Martin

Hi Martin,
I'm sorry, but I can't tell you more. I never tried to use a resource DLL.
I also saw your previous message "difference of custom controls from NT to 9x". I replied just to be sure you was using the 'recommended' method.
When I have some time, I will do an experiment.
As for now, maybe you will have better luck with more experienced programmers. I hope 
Cheers,
Paolo.

Only a few questions:
What do you mean with "custom controls"?
I suppose you have a static control (or some other standard control) in your dialog resource that gets subclassed later in the code, so why is that dialog different from the others?
And if you create a custom control at run-time, then you should have no problems at all, right?
How are the custom controls implemented in the code?
I have no other ideas...
Paolo

The AfxSetResourceHandle() only sets the resources for the current module.
If the custom controls and Active-X are in another DLL, then you need to create your resource DLL as an MFC Extension DLL, then it will get added to the CDynLinkLibrary list of DLL that will be searched for additional resources.
If you visually trace through the code that loads dialog resource templates, or even the CString LoadString member function, you will see examples of this internal CDynLinkLibrary list in use.

CustomControl
is that icon on the tool bar of the dialog editor with the
human head on it. <g> no pun intended.
Martine I usually get this kind of promlem when I forget to Register my custom window class.
But I don't know why it does not work on win 98. is it diffrent

Hi there, thank you very much for your help!
You've led me to the right path.
The LoadLibrary etc. is alright, the problem was the external resource DLL in conjunction with a custom control.
I have to register the window class of the control with the WNDCLASS-structure.
One element of this is the hInst, which most of the controls (Grid, BitmapViewer etc.) fill with AfxGetInstanceHandle(), which is okay in most cases.
But: here I needed AfxGetResourceHandle(), as I have to register the control with the resource DLL!!!
I still don't know why it worked with NT, but...
Greetings, Martin ))))

Hi,
looking for CodeWright forum.........can any1 help?
tnx
Yaron

Hi Yaron,
At first glance, strange to see something about CodeWright here on this site. But this proves still a lot of people ar using this powerful and extremely adaptable editor.
In the past, I've asked the guys at StarBase (formerly known as Premia Corporation), if there was somewhere a CodeWright forum. But unfortunately, so far, it doesn't seems to exist, at least not under their 'wings'. I could have used such a forum myself also very well in the past, but I always had to find the solution myself (which is highly interesting, but sometimes also heavily time consuming...  ).
Anyhow, can you more specific tell us what you're looking for? Perhaps other people, who are heavily using CodeWright, can help you.
Regards,
Geert
