you asked before, and got several answers which seemed to be good starting points. I personally defended you from some of those who despaired at your original post. we should be helpful to those trying to learn, I felt.
but you didn't reply to those answers and have just posted essentially the same question again.
So - did you not bother to read those answers? did you not understand them?
If you don't even TRY to help yourself, you're going to find it pretty hard to get help from anyone - and I think you have already outstayed your welcome on CP

Hay,
I looking for open source code in c language which schedule/deschdule a functions that will run in a new threads, so for example I can schedule the function to run every 30 minutes in new tread.
I want to use this source in my program as an infrastructure service.
I prefer using a source which will compiled on Linux and Windows platforms.
Please, any help - link

You mean code to create a thread?
just use
DownlinkThread = CreateThread(
NULL, // default security attributes
0, // use default stack size
Func, // thread function
0, // argument to thread function
0, // use default creation flags
&MsgThreadId); // thread identifier
The thread function is
WORD WINAPI Func( LPVOID lpParam )
{
while(1)
{
Sleep(30 * 60 * 1000);
}
return(0);
}
Substitute CreateThread with pthread_create and Sleep with uSleep for the Linux version

I know how to di it, I looking for more complicated thread events infrastructure which I can schedule to promise order and timing of events.
What aboute to schdule event to run (every 30 seconds, or to kill all created threads in one time.
I looking for the source of it as part of sharing code via the internet, and also learn new ideas.
BTW I found till now the "cheap thread" - a library of portable C routines to implement cooperative multitasking with prioritized scheduling, but they actully not using thread creation.
Any other links?

I created an MFC application and added Printing and Print Preview capability to a CMyFormView derived from CFormView. The problem I have is
that the "Prev Page" and "Zoom Out" buttons on the Print Preview toolbar are
always disabled. The "Two Pages" button and "Next Page" are enabled and work
correctly.
For the Prev Page button, I set CPrintInfo::SetMaxPage() and CPrintInfo::SetMinPage(). However, this doesnt work to enable the Prev Page button. In debug mode, I could see that CPrintInfo::m_nCurPage value was corrent within OnPrint() method when the program is in print preview. Anybody knows how to enable Prev Page button in Print Preview dialog?
Thanks

I have to have a list of choices in a text menu for a console app in C. The text menu is to be populated from strings read from an INI file.
Anyone ever done anything like this?
For example:
[Model-A]
1="XYZ, Location = ABC"
2="GHI, Location = DEF"
I want to read the section then populate some strings based on the number of keys read. The string then is parsed using the string delimiter.
Appreciate the help.

Well, if you're doing any of this in C++, CodeProject has quite a few good examples[^] to get you started. Otherwise, I'm sure someone[^] has come up with a solution

I do have an IniFile Class but the majority of code is ANSI C. I have an INI file that is read and choice are presented to the user with a static text menu. If the INI file changes (grows) then I have to rev. code. I would rather rev. the INI file.

Choice 'C' but not using C# which the link in choice 'B' is based upon.

Google the GetPrivateProfileString API to help read from an INI file. Once you have the values you can create the menu using regular STDOUT and STDIN routines such as printf, scanf, getchar, gets et al.

I want to put a Login form at the beginning of my project with using VC++ MFC along with validations.I have created a table using MS-ACCESS giving Username and Password as column headers.Now I want to connect the MS-ACCESS table contents with this VC++ MFC form.So if I enter the name and password in the edit boxes which are in the Login form,it should check that particular data whatever is typed in the edit boxes with the records in the MS-ACCESS say in login.mdb and pop a messagebox if it is incorrect,else the user must be allowed to enter the next form.S how to do that.The same thing I have done in Visual Basic as follows,but now I want the equivalent code in VC++ MFC,can anyone pls tell me...?
Private Sub cmdOk_Click()
Dim cnt As Integer
adLogin.Recordset.MoveFirst
cnt = 1
If txtLogin = "" Or txtPassword = "" Then
MsgBox "Invalid UserName or Password"
Exit Sub
End If
While Not adLogin.Recordset.EOF
If adLogin.Recordset(0) = txtLogin.Text And adLogin.Recordset(1) = txtPassword.Text Then
Unload Me
'mainForm.Show
frmOption.Show
Exit Sub
Else
adLogin.Recordset.MoveNext
cnt = cnt + 1
End If
Wend
If cnt >= adLogin.Recordset.RecordCount Then
txtLogin.Text = ""
txtPassword.Text = ""
MsgBox "Wrong User Name or Password"
txtLogin.SetFocus
End If
End Sub

hello,
i want to start and stop other process (win32 vc++ application without gui) in a mfc dialog application. please tell me how to do that ?
for stopping, i read that TerminateProcess() can be used but it should be used in extreme circumstances. The state of global data maintained by dynamic-link libraries (DLLs) may be compromised if TerminateProcess is used. so is it safe to use it ??

Hello,
rahuljin wrote: want to start and stop other process (win32 vc++ application without gui)
What kind of an application are you developing?
You can use ShellExecute[^] to create a process. Or if you want more options and possibly control over the spawned process, there is CreateProcess[^]
No, you shouldn't be using TerminateProcess(), but again if you say what kind of application are you writing (and if you have written the spawned process as well), a better alternative might be suggested to you.

mfc application creates some text files which are used by other win32 c++ program. if i try to access the files through mfc application while win32 c++ program running, it causes the crash of the mfc application (beacuse i dont used any 'if' for file open and i cant).
i used the createprocess() and it is working great.

I don't understand this. If you could explain me better, and tell me what exactly are you trying to achieve, I may be able to help you.

i created the win32 c++ application long back when i dont have any idea of mfc. it is working fine.
with mfc, i create a gui which accept the some content and save them in text files. these text files are then used by the win32 application. win32 application runs at startup of windows and it takes the information from the files and starts using it (it is socket application so it will not read the file again until it receives some information for the ip which is saved in the text file).
so i want to restart the win32 application when closing mfc application so that win32 application can use the updated text files.
actually i want to use TerminateProcess() and then start it with CreateProcess() function. but i read that TerminateProcess() can create problem with DLL structure.

please tell me how to use TerminateProcess() function. if there is an alternative for this function, please suggest.

might want to look at ExitProcess() also

Hello All;
