Yes, it is the desktop SQL engine. Since it is quite a bit faster it might well help.

how do you create an extra item on your right click menu when you right click on a file? Can this be done in VC??

Using shell extensions is the most common way, but there is a very less complicated way using the registry, which allows to add commands to the "right click menu" without writing a COM component; just adding a registry key.
Here is a example:
We want to add a new option in the context menu of ".exe" files, well, we open regedit and go to the key "HKEY_CLASSES_ROOT\exefile" (or ".XXX" for other extension). Here, it must be a key called "shell" (if it doesn´t exist, we should create it). Under this key we add the name for the new option in the menu, for example "Scan". Now into the "Scan" key, it should be created a new key called "command", whose default value should be the name of the command to execute when clicking our command, for example "c:\scanner.exe %1" ("%1" is replaced by the file clicked in the explorer)
This allows not adding icons or other extended features.

This question is part logic and part functionality...
I'm not familiar with the combo box control, but want/need to use it.
I have several items in my combo box control (drop down list) and other controls in my dialog that depend upon what is currently selected.
I want my other controls to change when the user "really changes" an item in the drop down list. For example, upon leaving the drop down list, if the selection has changed from what it previously was, then change my other controls. If the user has scrolled through the list, but has left the selected item the same, then don't change my other controls.
In short, I need to know how to react to CComboBox upon exit.
Thanks,
Johnny

You need to handle the CBN_SELCHANGE notification message from the combobox. You must check, if the selected item is the same as before yourself.

use the class wizard and add a handler for the CB_SELCHANGE message

This would suggest handling CBN_KILLFOCUS. However, its usually CBN_SELENDOK - sent when user selects something from dropdown list.
Are you using MFC?

Group,
thanks for quick reply. Yes, I'm using MFC and VC++6.0.
Here is my problem... when I get in my CComboBox control (drop down list), I can use the up/down arrows or cursor to move in my list.
However, I don't want the reaction by other buttons to happen until the CComboBox "no longer has focus AND the selection is different than when entered."
I have tried the following:
void CForceProtectDlg::OnSelEndOkCallSign()
{
//if (m_CallSignIndex != m_comboCallSign.GetCurSel())
// Reset(); // Reset other controls
}
void CForceProtectDlg::OnSetFocusCallSign()
{ // Get the index before changes happen
m_CallSignIndex = m_comboCallSign.GetCurSel();
}
void CForceProtectDlg::OnKillFocusCallSign()
{
if (m_CallSignIndex != m_comboCallSign.GetCurSel())
Reset();
}
None of these have given me the action I want. Stumped...

Does anyone know how to auto increment the build and version info in VC6? Admittedly, I'm a little lazy when it comes to this sort of thing.
Thanks for any help.

No. VS.NET ships with MFC 7.0.

MFC is here to stay! The .NET Frameworks relies on the whole C#, managed C++, language. MFC relies on C/C++. C# is weak! If you want to learn C#, you might as well learn VB. I would learn VB before learning C#.

MFC is supported in VS.NET.
I thing the principal question is Win32 "unmanaged" software development (API,MFC,ATL,... You name it) versus .NET development.
.NET seems to bring more productivity, I like the component oriented approach and C#. It has some drawbacks - performance (VM, Garbage collector), it ties You to Microsoft more than before. And it's new, not proven and commonly spread. With current projects we can't use it with our customers - problems with sysadmins, older HW and SW.
.NET is pushed from Microsoft with great force, so it seems that we are going to program for it, like it or not. But the unmanaged programing is not yet overcomed and will continue to have it's use.

Where can I find details on the differences between defining variables/functions public, protected and private in a class (or maybe someone can explain?).
John
|
|
|
|
|
Private: Only your class may access the variables/functions, your can't access then from outside the class
Public: Functions/variables can be accessed from both inside and outside the class
Protected: Functions/variables can only be accessed by the class and any classes derived from that one
Correct me if I'm wrong

BUT, that would require me getting out of my chair to go get the book, and I would have to talk (*shudder*) to a fellow employee to get the book.
ROFLMAO
Yeah, dumb-ish question, I kind of knew the answer...but I guess I was hoping for something enlightening...
BTW its great how fast questions get answered here!
