changing read-only CEdit background color

Is there a way i can change the background color or a read-only CEdit ???
i can't use any classes for a modified Edit control because the edit is already too much embedded in my app i'm not gonna change everything again.
It's a read-only edit so the background is gray by default but i want to make it white.

Mike Dunn's C++ FAQ explains how to do it for static controls here. For edit boxes it's the same but handling WM_CTLCOLOREDIT instead of WM_CTLCOLORSTATIC (if you do it the MFC way, though, it's exactly the same for both types of controls).

If the parent dialog gets the WM_CTLCOLOR message for the edit (OnCtlColor) you should be able to identify the control and modify the background brush returned and call SetBkColor and SetTextColor on the dc passed in.

I think there's another way to do it but can't recall right now - check the July 96 MSDN C++ QA for more on this.

oops...I mean the July 96 MSJ - but the article should be on the MSDN lib.

Subject: Stored procedure ADO

Hi,

I working with Stored Procedure with a SQL Database.

I use a procedure for writing to the database 2 paramaters (a STRING and a INTEGER).

My procedure working with the STRING but not when I writing a INTEGER. It is probably in my code at pParam1.
If anyone can help me for this is great.

My code :

_ConnectionPtr pConn("ADODB.Connection");
_ParameterPtr pParam2,pParam1;

CString strFileName = "JK010104";
int iBetacart = 1;
pConn->Open("provider=sqloledb.1;database=ARCHIVES_TVI;server=100.100.100.100;uid=Me;pwd=xxx;network=dbmssocn","","",adConnectUnspecified);
_CommandPtr pCmd("ADODB.Command");
pCmd->ActiveConnection = pConn;
//Cmd->CommandText = "StartFileNum";
pCmd->CommandText = "ResetFileNum";
// pCmd->CommandText = "EndSuccesFileNum";

pCmd->CommandTimeout = 20;
pCmd->CommandType = adCmdStoredProc;
// _RecordsetPtr pRst("ADODB.Recordset");
// pRst = pCmd->Execute(NULL, NULL, adCmdStoredProc);

pParam2 = pCmd->CreateParameter ( _bstr_t ("File_Name"), adVarChar,
adParamInput, strFileName.GetLength (), (_bstr_t) strFileName);

pCmd->Parameters->Append ( pParam2);

Param1 = pCmd->CreateParameter ( _bstr_t ("AutomatNr"), adInteger,
adParamInput, sizeof (int), _variant_t ( long (iBetacart)));

pCmd->Parameters->Append ( pParam1);

_RecordsetPtr pRecordset;
pRecordset.CreateInstance(__uuidof(Recordset));
pRecordset = pCmd->Execute(NULL, NULL, adCmdStoredProc);

CTime, strftime, Format, %z/%Z

I am experiencing a problem with time formatting that I'm hoping someone else has encountered and perhaps has some advice.

In a nutshell, with either CTime::Format() or strftime(), the timezone specifier does not work properly -- both %z and %Z return the full name of the time zone. (%z should represent the abbreviated name, e.g. CST and %Z should represent the full name, e.g. Central Standard Time).

In the following example, both would return the exact same string (well, OK, there would be a slight time difference):

CTime time(CTime::GetCurrentTime());
CString cstrDateA = time.Format("%a, %d %b %Y %H:%M:%S %z");
CString cstrDateB = time.Format("%a, %d %b %Y %H:%M:%S %Z");

My development setup:
Windows 2000
Visual Studio 6.0 Enterprise Edition (with latest service pack)

"If ye love wealth better than liberty, the tranquility of servitude better than the animating contest of freedom, go home from us in peace. We ask not your counsels or your arms. Crouch down and lick the hands which feed you. May your chains set lightly upon you, and may posterity forget that ye were our countrymen."

Hello!

If you look at the source, D:\Program\Microsoft Visual Studio\VC98\CRT\SRC\STRFTIME.C, in the function _expandtime then you will see that case('z') and case('Z') is treated the same!

So the doc is wrong ...

For an another perculiar thing try this:

CTime time(CTime::GetCurrentTime());
CString cstrDateA = time.Format("%a, %d %b %Y %H:%M:%S %z");
COleDateTime ttime(COleDateTime::GetCurrentTime());
CString cstrDateB = ttime.Format("%a, %d %b %Y %H:%M:%S %z");

Strange or ??

WebBrowser-Control: FileDownload-Event

7-Jan-02 5:46

Hello everybody!

I've got the following problem: my app uses a WebBrowser-Control, but I don't receive the FileDownload-Event, which would allow to suppress the Download-Dialog.

I'm using the following code:

// Declaration of the Eventsink Map
BEGIN_EVENTSINK_MAP(CMainWnd, CFrameWnd)
  ON_EVENT(CMainWnd, IDC_WEBBROWSER, 270 /* FileDownload */, OnFileDownload, VTS_PBOOL)
END_EVENTSINK_MAP()
//
// ...
//
// Implementation of the Event Handler Function
void CMainWnd::OnFileDownload(BOOL FAR* Cancel) 
{
  AfxMessageBox("Why is this message never displayed?");
}

Has anybody got an idea why this doesn't work? Thanks in advance for an evetual answer!

UNICODE file I/O

7-Jan-02 5:15

Can anyone help me with how to write and read Unicode strings to and from file? I am using wifstream and wofstream and wstring. I can't find any reference material at all about how to do this. Can anyone help or point me at an example or other online resource?

Many thanks

Embed objects with custom icons in a CRichEditCtrl

7-Jan-02 3:45

Hi,

I'm writing an MFC-application based on CRichEditDoc/View, where I need to embed files in the document (displayed as icons). Everything works just fine, except for one thing: I can't figure out how to embed an object with a custom icon (or rather, a MetaFilePict = Icon + Label), all I get is the ugly default (such as a Package icon for non-OLE objects).

I know how to properly create the custom metafilepict (it's been tested independently), but when I use COleClientItem's SetIconicMetafile() to assign it to the object, it doesn't work. This is _after_ I've called SetDrawAspect(DVASPECT_ICON), which default COleClientItem implementation resets the icon, but _before_ the view's InsertItem() method. What else do I need to do?

If anyone could give me some hints on what I need to do, I'd really appreciate it! Smile | :)

How can I add my own button to the title list, or what it is called in English.
A good example is ICQ: The window is a child but the ICQ window has a minimize button too!
So, how to add a button in my window that only has a close button (the 'X' button)!!!!??????????????

When yo make the call to start the CRectTracker object tracking, make a call to ClipCursor(Rect) to limit the area the mouse can move in. Once complete call ClipCursor(NULL)

Hi Im not sure exactly what you want. You have your m_rect now do you mean that you want the resize bar inside the rect or that you only want to be able to move the rect to shrink (not enlarge).

If it is the first case use

m_tracker = new CRectTracker(rect,CRectTracker::resizeInside );

Here is how I used it to initilise my CRectTracker to move objects in my dialogs (warning untested code)

CDC* pDC = GetDC();
if (m_tracker)
{
	delete m_tracker;
	m_tracker = NULL;
}
LPRECT rect = new RECT;
CWnd* wnd = (CWnd*)(GetDlgItem(IDC_EDIT1));

wnd->GetWindowRect(rect) ;
ScreenToClient(rect) ;
 
m_tracker = new CRectTracker(rect,CRectTracker::dottedLine  | CRectTracker::resizeOutside | CRectTracker::hatchedBorder );
m_tracker->Draw(pDC);
delete rect;
rect = NULL;

You move the control inside all dialogue, and it is necessary for me to move the control only in what or parts of the dialogue limited m_rect.
All the same thank, for attention to my problem. If there will be ideas I with pleasure shall listen them!

Ive seen posts on the web saying that there are programs that can get the C/C++ code from an exe. Is this actually possible? It must be because what goes one way must be able to go back again.
If this is true could it mean the end of 'payed for' software?

.NET or not .NET? MFC is the question......

Yes, these programs do exist. However, the quality isn't very good.

I have taken software and created an ASM file before and then figured out how the software worked. In some cases it was to make sure my software acted as people expected (i.e. SendKeys from a C++ program). In other cases it was to get a full understanding of how a routine worked (i.e. VariantChangeTypeEx: when we were switching to it from a C based variant systems.)

Now...

The legality of a lot of this is VERY VERY VERY questionable.

Decompilation

As far as these things being the end of 'paid for' software, not in a million years. If fact, this desire for the end of 'paid for' software is actually very counter productive to the software industry. The quickest way to kill innovation is to make it all free.

Hi

I was wondering if anyone out their know of a sevice pack fixing bugs in Microsoft's eMbedded Visual Tools 3.0. I had to reformat my drive to get it out the registry the last time I installed it. Now I need to use it rather desparately but am feeling a bit off about reinstalling it. Did anyone else have problems with debugging in this environment? Much appreciated Hmmm | :|

I use it on W2K Pro to debug applications (and drivers) on iPac.
The debugger stinks.
Let me rephrase that:
The EVC debugger really stinks!!!
The debugger is SLOW and locks up all the time, then I have to kill EVC.EXE and reset my iPac.
I am desperate for an update, but to my knowledge there is none.
Why o why are there 5 service packs for Visual C++ but none for this CRAP!

Been using for months with no problems. Debugger works GREAT!!! (hehehe, see previous reply.)

However, I noticed a few things.

1. Don't use the emulator.
2. Get an ethernet card for your CE device. Otherwise the debugger is SLOW AS A DOG!!!!

1. the emulator when used for debugging applications works fine...
2. who do you think writes the drivers for the CE ethernet cards? I really have problems when writing this driver for a PCMCIA ethernet, a wireless LAN or a bluetooth card... I have to debug over USB (with the cradle).
Do you know a good kernel debugger for WinCE 3.0 iPac devices? I do not want to use the Platform builder and generate my own CE platform, since I need access to the already existing iPac platform.
