Hi
Can someone explain PeekAndPump() function and why should we use it with a ProgressBar??
Is there a standard definition for this function???

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.

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.

Dear Elaine,
Thank you for the direction. If you don't mind I would really like to see your sample project. You can send it to me at stonematthies@hotmail.com.
thanks. Mavrock

Hi there,
I just wanted to add new records to end of record list like this:
Gen
Brus Lee
Arnold
Hadi 
and etc.
I wrote it:
m_rs.AddNew();
m_rs.SetFieldValue("NAME", "Gen");
m_rs.SetFieldValue("NAME", "Brus Lee");
m_rs.SetFieldValue("NAME", "Arnold");
m_rs.SetFieldValue("NAME", "Hadi");
m_rs.Update();
But when i run this code, the result is strange ...
the result is it:
Hadi
Arnold
Brus Lee
Gen
vice versa ???
But why ?
What's my wrong ?
Help me please !

I don't know what happens but I didn't recive all the message. I saw your question here but I didn't recibe this question...
I make a question for you.
You tried with the following?
m_rs.AddNew();
m_rs.SetFieldValue("NAME", "Gen");
m_rs.Update();
m_rs.AddNew();
m_rs.SetFieldValue("NAME", "Brus Lee");
m_rs.Update();
m_rs.AddNew();
m_rs.SetFieldValue("NAME", "Arnold");
m_rs.Update();
m_rs.AddNew();
m_rs.SetFieldValue("NAME", "Hadi");
m_rs.Update();
Best Regards

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

I suspected That...
I Don't want to start an international conflict, is for that you will live...
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);

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...
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?
Kuphryn

Okay. Thanks.
CheckAbdoul posted a link at MSDN Newsgroups.
http://www.flipcode.com/tutorials/tut_dll01.shtml
That tutorial helped me.
The tutorial he gives helps me considerably. I am confused at the point where the compiler produces a .dll, .lib, and .h file.
For implicit implementation, you have to including the .h file in the source code and import the .lib file. I do not quite understand that process. I believe the compiler only produce a .dll file and you import that file in your source code only. However, I learn that is true for explicit implementation.
Well, explicit implementation is quicker because you do not have to search for the .h and .lib as well as .dll file. Nonetheless, both implicit and explicit implementations are essential.

Okay. I just cannot get the compiler to compile the dll without errors.
I have uploaded the entire dll project to my website. Please check it out and see if you can determine the error. I use the exact same technique Jeffrey Richter shows in his book. However, the compiler saying a .pch file cannot be found. Second, I do not understand why Visual C++ includes the stdafx.h file in all projects.

Please post if you find an unconditional working solution.
Thanks,

Okay. I finally fixed the problem with help from Dean Harding of GameDev.
One more questions.
Here is one working DLL declaration.
-----
#if defined(FIRSTDLL_DLL)
# define FIRSTDLL extern "C" __declspec(dllexport)
#else
# define FIRSTDLL extern "C" __declspec(dllimport)
#endif
-----
I am able to compiler the DLL using this code too.
-----
// FirstDLL.h
#ifndef FIRSTDLL_H
#define FIRSTDLL_H
#define IMPORT __declspec(dllimport)
#define EXPORT __declspec(dllexport)
#ifdef __cplusplus
extern "C"
{
#endif
class EXPORT myClass
{
...
};
#ifdef __cplusplus
}
#endif
#endif
-----
Is there an advantage one declaration has over the other?
Thanks,
Kuphryn

Hello,
I have a dialog bar that contains the following SliderCtrl message handler:
OnCustomdrawSliderProg(NMHDR* pNMHDR, LRESULT* pResult)
Inside this handler, I call another function to update a 2nd dialog bar's windows. However, when this occurs, the slider control is randomly (time) redrawn on the 2nd dialogbar's client area at random places. I assume I'm mixing device contexts somehow.
Functionally I want my 2nd dialog bar to have a 'live' response to a user adjusting the CSliderCtrl on the 1st dialog bar. Has anyone a solution for a clean way to do this? I've tried to handle the lose-focus SliderCtrl message (works without odd slider drawing), but then if the user uses the arrow keys, the 2nd dialog bar is not updated.
Thanks!

Handle WM_HSCROLL - this message is sent whenever thumb is moved using mouse/keyboard. When user releases the mouse, you'll get WM_HSCROLL with TB_ENDTRACK code. You'll also get TB_ENDTRACK after each keypress changing thumb position.
