Marking a row in a CListCtrl

After having used CListCtrl::FindItem() to find the index of an item I want to mark the row with that index how do I do that?

I also committed the crime of posting a programming question in the Lounge.

To select item number i in list control use:
m_list_ctrl.SetItemState(i, LVIS_SELECTED, LVIS_SELECTED);
To ensure that item number i is visible, use:
m_list_ctrl.EnsureVisible(i, FALSE);
If you want full row selection in list control:
m_list_ctrl.SetExtendedStyle ( LVS_EX_FULLROWSELECT );

Mark?
If you by "mark" mean "select" then use the SetCurSel(index) method

The PeekAndPump function you're referring to is probably part of some example. There's no API or MFC function with this name.

Name of this function suggests that there's a loop inside which checks for messages with PeekMessage - hence the 'peek' part. If there's any message, it's dispatched to appropriate window; this is the reason for 'pump'. The peek'n'pump solution is needed because there's some activity going on and progress bar shows the progress of operation.

Thread and serial port

I am new to programming. I have been given the task of making an application that recieves commands via the serial port. and then displays a notification that the commands were recieved. I have been told that I need to use a thread to do this. I'm not sure where the thread goes, I.E does it go in the source file or the header file? Or do I declare it in the header file and then put the functionality in the OnInitialDialog function?
Thank you for any help.

Mavrock,
I have done something similar but nowhere near doing an article yet.
Basically:
1. Create a dialogue box
2. Insert the Mircosoft communications ActiveX component into it.
3. Create a variable name for the ActiveX component. This then creates a class for the MSCOMM component (prompt displayed).
4. Set the RThreshold property to 1. This causes an OnCommEvent for every character received.
5. In the OnCommEvent() procedure, event 2 is for soemthing received.

If you want a small sample project let me have your email address and I'll forward it.
I have used this on Win98 and NT4 with no problems.

Anyway, when you insert records in a DB, you should not rely on the insertion order to retreive the data later.

It's obvious that if you see the records in diferent order, is by a Index cause.....

How can I make a property of a COM to be the default property, say in Field object, it has get_Item(VARIANT *pval). I want in VB client, it can be accesses as MyObj.Field = "hello" instead of MyObj.Field.Item = "hello".

Give it an id of DISPID_VALUE (that's 0) in the IDL :

[propget, helpstring("property Item"), id(DISPID_VALUE)] HRESULT Item([out, retval] BSTR *pVal);
[propput, helpstring("property Item"), id(DISPID_VALUE)] HRESULT Item([in] BSTR newVal);

DLL Fundamentals :: MFC

Hi.

I am learning DLL creation and implemention from Programming Applications for Microsoft Windows by Jeffrey Richter. Richter demonstrations are straightforward and appear simple. However, I cannot implement a working at all using Visual C++ .NET.

I tried using the DLL Wizard and hardcoding a .cpp and .h file. Neither method worked. I would like to create a simple dll with functions I can use in any C++ programs I work on including MFC. In fact, all my Windows program are MFC. Here is an example of the code.

-----
// myDLL.h

#ifndef myDLL
#define myDLL extern "C" __declspec(dllimport)
#endif

class myDLL MyClass
{
MyClass();
void FunctionOne();
int FunctionTwo();
~MyClass();
-----

-----
// myDLL.cpp

#define myDLL extern "C" __declspect(dllexport)
#include "stdafx.h"
#include "myDLL.h"

MyClass::MyClass()
{
}
...
-----

The code above uses the exact sample algorithm Richter presents in his book. It is does not work. I would like a good solid working example of creating a dll that works in both MFC and non-MFC Windows programs.

Thanks,
Kuphryn

Try this:

1. open a new 'MFC AppWizzard (dll)', choose project name. >>> NEXT
2. Choose 'MFC Extension DLL (using shared MFC DLL)'. >>> FINISH
3. Add to project your classes ('*.h' + '*.cpp').
4. Add AFX_CLASS_EXT macro before your class name definition:

class AFX_EXT_CLASS CYourClass
{
public: 
void Method1();
//...............
//...............
};

5. After compiling a Release version, Pick out of the 'Release' folder
2 files: 'YourDLL.dll' + 'YourDLL.lib'.
6. In the project you wish to use'em, paste in its dir both of'em, and add
to the project 'YourDLL.lib' + 'YourClass.h' (with AFX_EXT_CLASS)
7. Compile and pray... Cool | :cool:

8. Please reply if this works well.
9. Succsess....

Okay. Thanks.

I will try your solution. I do have a question too. I thought when you create a DLL, the compiler produces just one simple DLL file in the release version. How come you mentioned a .lib and .h file?
