add a member variable for that edit box e.g. "m_deEditBox" using the class wizard and set the category as a control and the variable type should change to be automaticaly CEdit.
Wherever you want to receive focus use the SetFocus() and that should do the trick
e.g. :
m_deEditBox.SetFocus();
Only make sure m_deEditBox is visible within the class you are using!

Calling SetFocus to set the focus to a control on a dialog box is wrong! See here[^] for details.

First, Thanks for the correction.
Second, sorry this is long but here goes;
When i tested SetFocus(), i placed it in two buttons as:
void CSetfocusDlg::OnBfirst() //first button
{
// TODO: Add your control notification handler code here
m_deOne.SetFocus();
}
void CSetfocusDlg::OnBsecond() //second button
{
// TODO: Add your control notification handler code here
m_deTwo.SetFocus();
}
and it worked just fine.
But if i am getting it right, if there is a button in a dialog, SetFocus() is reserved for the default push button, right?
This means that even if i put m_editControl.SetFocus() in OnInitDialog(), i would still not get the desired effect of setting the cursor to the Edit control(what i understand from the site you directed me and practically i have tried, so i was very wrong indeed).
Ofcourse it makes sense to use the WM_NEXTDLGCTL but i cant get the message in the class wizard. Then how do i code the handler? Please help!

Oops sorry, using SetFocus() won't work. But i am learning. Thanks for understanding.

I'm somewhat confused about this api. My local copy of MSDN aswell as the online version state that this api requires win2k and upwards. But many code samples I have found, including several here on CP, state that it can be used on win98.
What's the deal?
|
|
|
|
|
In my MSDN (Visual studio 2005) it is as
Requires: Windows XP, Windows 2000 Professional, Windows NT Workstation, Windows Me, Windows 98, or Windows 95.

Thanks for confirming that. I wonder why they changed the documentation? I don't suppose you could copy and paste the paramaters, just in case it has changed. Though I doubt it very much.

Just for confirmation...
Platform SDK: Device I/O
DeviceIoControl
The DeviceIoControl function sends a control code directly to a specified device driver, causing the corresponding device to perform the corresponding operation.
BOOL DeviceIoControl(
HANDLE hDevice,
DWORD dwIoControlCode,
LPVOID lpInBuffer,
DWORD nInBufferSize,
LPVOID lpOutBuffer,
DWORD nOutBufferSize,
LPDWORD lpBytesReturned,
LPOVERLAPPED lpOverlapped
);
Descriptions goes........
Requirements
Client Requires Windows XP, Windows 2000 Professional, Windows NT Workstation, Windows Me, Windows 98, or Windows 95.
Server Requires Windows Server 2003, Windows 2000 Server, or Windows NT Server.
Header Declared in Winbase.h; include Windows.h.
Library Link to Kernel32.lib.
DLL Requires Kernel32.dll.
Hope now OK...

Exactly as my copy states, with the exception of win95 through winME. Strange eh...

I have added new classes to my project and
I do not have a browse data to show me the classes hirearchy.
The project setting has "Generate browse info" checked.
Rebuilding all does not help.
Is there a way to rebuild the browse data manually?
Thanks for your help.

Alok, thanks a million for your help.
Scary, talking about "major surgery" here.
Somehow all my intermediate directories went out of my “ working folder”.
I am used to .clw to get out of synch, but this was different.
Thanks again

Hi all,
I am developing a snippet for extraction of msg propeties, I am using
outlook 2003. Now my problem is the current mapi_utils does not
extract the PR_HTML body which I need to show the embedded files in
the body and the right format of the body as well.
What I exactly need is the HTML format of the .msg file.
The current mapi_utils are only applicable upto outlook 2000.
Please help me
Thank you,

I wrote a program that calculates a multivariable linear regression. Everything works. He can calculates the parameters (4 times) and writes them in a text file.
The problem is that when he arrives at the end of the calculate function (onbtnClicked) there comes a popup with next message:
Unhandled exception at 0x006329c2 in RegressionTool.exe: 0xC0000005: Access violation reading location 0xfeeefee8.
Visual studio opens the file dbgheap.c and goes to line 1595.
When I remove some lines, especially the inverse line, he doesnt give the message anymore.

If you look at the call stack, you should be able to work your way back to the
offending line in your code. Somewhere, a pointer is getting messed up.

Alright I found the place. It is in the destructor of my Matrix class. But it only happens wen inverting. I don't seem to be able to find why.

There are many things that can cause an access violation; saying “I’m getting an access violation, please help,” is like going to a doctor and simply saying, “I don’t feel well.” At a bare minimum you should provide the following:
- The callstack to the faulting code.
- The source code around the faulting code.
One clue I can see from your description is the address “0xfeeefee8”; it’s nearly 0xfeeefeee. See here[^] for details. It looks like you might have a dangling pointer!

Alright, don't laugh.
I usually use Visual C++ 6.0 for just about anything but my latest project is using Visual C++ 7.1 and I'm trying real dialogs (property pages) for the first time in this environment and I'll be darned if this collosal piece of %@&* does not set up my DDX_Text statements for my edit controls when I add a variable for both the value and the control, or even just the value without a control variable.
I'm using the "Add Variable" thingy when I right click on the control in the dialog editor and adding a variable for both the value and the control.
What am I doing wrong or do I need to hand code those as well?
// This is what I'm used to in Visual C++ 6.0
void CSomePropPage::DoDataExchange(CDataExchange* pDX)
{
CPropertyPage::DoDataExchange(pDX);
DDX_Text(pDX, IDC_SOME_SYMBOL, m_nSomeInteger);
DDX_Control(pDX, IDC_SOME_SYMBOL, m_editSomeControl);
}
// This is what I'm getting in Visual C++ 7.1
void CSomePropPage::DoDataExchange(CDataExchange* pDX)
{
CPropertyPage::DoDataExchange(pDX);
DDX_Control(pDX, IDC_SOME_SYMBOL, m_editSomeControl);
}
|
|
|
|
|
Well, I'm finding these DDX/DDV routines are still fairly weak. Numeric does not allow negative sign etc...
I think some custom routines are needed.
Any ideas or insight still welcome.

Where can I go to get an index for error numbers? I run this code and get 102 errors Many of them: error C2784
Salestaxrate = .10;
Discountrate = .10;
int pizzaCost, popCost, chickCost, discount, salestax, subtotal, dueAmt, totAmt;
totAmt = pizzaCost + popCost + chickCost;
discAmt = (pizzaCost + popCost) * discountrate;
subtotal = totAmt - discAmt;
taxAmt = subtotal * salestaxrate;
dueAmt = subtotal + taxAmt;
cout << "Please enter the customer name.\n" name;
cin >>name;
cout << "Enter the pizza cost.\n" pizzaCost;
cin >>pizzaCost;
cout << "Enter the pop cost.\n" popCost;
cin >>popCost;
cout << "Enter the chicken wing cost.\n" chickCost;
cin >>chickCost;
cout >> "Total for food".\n; totAmt;
cout >> " Less discount on pizza and pop.\n" discAmt;
cout >> " Plus tax .\n" taxAmt;
cout >> "Total Due.\n" dueAmt;
return 0;
}

you have some errors:
1) "Salestaxrate = .10;
Discountrate = .10;"
this variable have not type
2) in C++ values "Testvalue" and value "testvalue" are different;
3) operation '.' is't concatenate as it is in PHP
4) you must define value befor you use it
5) '\n' means beark line as '
' in html and it is purt of the string
you cant write: "test string".\n you must write "test string\n"
6) use MSDN it will help you
P.S.
find good book for beginers
