If you've designed it properly, my suggestion would be to simply click the Cancel button and then open the dialog up again. All of the initial (default) values will be present at that point and you will not have had to resort to some "reset" button.

How do i maintain the focus in a edit box? For example i was typing half-way in the edit box, however an event occur and the focus got changed. How do i set the focus to remain in the edit box.
This is wat i tried to do when the event occurs
<br />
if(m_alarmOn==false)<br />
{ <br />
m_alarmOn= true;<br />
<br />
CWnd* prev = this->SetFocus();<br />
prev->SetFocus();<br />
<br />
CreateThread(0,NULL,CSecurityDlg::playSound,this,0,0);<br />
}<br />
<br />
The above code reside in a OnBtnClick function. So when alarm is on, the button will be auto click....and the alarm sound goes off....
But in the process of these, i might be typing in a editbox. So i will lose the focus...How do i get it to stay?

Tks. I resolved it using pic control and defining a WM_action message instead. Thought this would be neater.

How do i include a header files directory of another library to my project's include file path.
|
|
|
|
|
Open the project settings.
Go to the C++ tab.
Use the combobox to go to the Preprocessor entry.
Under 'additional include folder' enter a relative or absolute path.
I prefer to use relative paths from the DSW file, since I might end up with a different drive letter or arrange items into different levels. Less work if things are relocated relatively to each other than a hard coded path to some specific drive in some specific rooted folder hierarchy.

Hi,
Do anyone know will DDE(dynamic data exchange) still be supported
in window longhorn ?
Thank

Hi all,
While i use
CreateProcess(
LPCWSTR pszImageName,
LPCWSTR pszCmdLine,
LPSECURITY_ATTRIBUTES psaProcess,
LPSECURITY_ATTRIBUTES psaThread,
BOOL fInheritHandles,
DWORD fdwCreate,
LPVOID pvEnvironment,
LPWSTR pszCurDir,
LPSTARTUPINFOW psiStartInfo,
LPPROCESS_INFORMATION pProcInfo
);
I want to pass a structure as second parameter(pszCmdLine) in this function. But somehow child process can't correctly get the structure! Should i do anything like "cast" or.. before i pass it? thanks for any advice!

How do you plan to pass the data of the structure ? You can't just pass a pointer to the second process because the pointer is only valid in the context of the original process.
I think you need to pass the value of each member of the structure as a text string to the second process and it must parse the values and "re-assemble" the data structure.

gosh - it didn't occur to me that he could be trying to pass a pointer

I don't know - I try to assume literal interpretations of questions. I could easily be wrong. 
I guess another option for him is WM_COPYDATA.
|
|
|
|
|
I also assumed they wanted to pass data or a pointer to some data.
|
|
|
|
|
The command line parameter is a string. Because it's a wide string, each character is two bytes. You should pass the parts of the struct as a comma seperated string and rebuild it in the process.

Generate a new GUID.
Make a memory mapped file (MMF) using this GUID as its name.
Pass this name as a command line argument to the new process.
Open the MMF from the second process and read your data from the MMF.

in jscript:
var shell = new ActiveXObject("WScript.Shell");
var fso = new ActiveXObject("Scripting.FileSystemObject");
Is there a way for MFC to do this and how?
Tnx in advance....

Hello my fellow programmers,
I am in the process of writing some front end software that takes to an engine management unit that will program it and perform data acquisition in real time.
I have written software for this before using the MFC Doc View Framework and I have had considerable success with this. However this new project is for a newer unit and will most probably have a life span for the next 5 years. The target operating systems for this will be Win98 SE through to XP.
My question is Should I be writing this in MFC or should I consider using managed C++ and the new .NET Framework. Any inputs/questions would be greatly appreciated.
Best Regards
Danny Nowlan

MFC. Simply because I don't think the .NET framework in C++ will give you anything that justifies having the ship the framework.

Christian,
I must admit that is a very valid point. Some of the machines we will ship too are very underspeced Win98 machines and I don't think they would take too kindly to the .NET framework. MFC I know very well and I know it works. Thank you for your consuel.

LOL - when I last used WTL it was really interesting, due to lack of support and docs. Do Microsoft officially support it now ? Is it being developed still ?

It is open source now[^] and still developed by original Microsoft guys.
I have seen quite a number of job ads mentioning WTL, so I wouldn't count it out.
My programming blahblahblah blog. If you ever find anything useful here, please let me know to remove it.
