I have a little application called updater.exe. This updater gets called by the other application called someapp.exe. Updater receives three arguments
1. calling application (full path of someapp.exe)
2. location of the installer file
3. installing destination folder
So when someapp.exe calls updater.exe it immediately exits (it will get overwritten). Because this exiting process isn't instant, updater should check if it's still "alive". How can I do this? Can I get some handle from 1st argument and check if application is still running?
Best regards,
Rostfrei

You could use a kernel object, as describes by Christian Graus here[^].

Have the calling process pass a HANDLE to itself to the callee. Make sure this HANDLE is inheritable and then when you call CreateProcess to create the callee ensure the bInheritHandles argument is set to TRUE. The callee can then call WaitForSingleObject passing in this HANDLE to wait until the caller has exited.

I have a char* that holds a numeric value of for example: 172,500 and I want to multiply this by another number and write the contents back to a new char*. Could someone give some example code on how to easily achieve this?
|
|
|
|
|
You can use atoi and itoa functions to achieve this.
atoi - converts string to int.
itoa - converts int to string.

Actually is there a comma (,) ?

There is a (,) in the string.
What I think I will do is write a class that can cater for all eventualities, as there is also a possibility of the number being in scientific notation, just to make matters worse!

You can do it simple... first filter out the comma.
If you are using the CString, use str.Remove(',') so that the comma will be filtered. Then you can convert it to integer using atol, atoi, etc., or _ttol, _ttoi, etc.

You want to make an installer. There's many ways to do this, commercial packages and freeware.
I use "Advanced Installer" -- they have a freeware version... http://advancedinstaller.com/feats-list.html#free[^]

Hi,
Is there any SDK of winzip through that I would be able to create zip file, or is there a way I can create zip file programmatically that can be opened by winzip and winrar utilities.

HBRUSH b = CreateSolidBrush(255);
SetLastError(0) ;
if( DeleteObject(( HGDIOBJ)b) )
{
printf( "brush deleted\n" ) ;
}
DWORD dw = GetLastError() ;
printf( "%d" , dw ) ;
----------------------------------
the above code returned..
brush deleted
0
when i debuggin this app gdi object count is incremented by one from 4 to 5(on windows taskmanager) when calling CreateSolidBrush, the deleteobject function return success but the gdi object count is still at 5.

I had faced the same issue regarding the brush and pen objects. But I failed to get a solution.
See my post in CP[^]

If you have the GDI object selected into a DC at the time of the DeleteObject(), the object will not be deleted. You must first use SelectObject() to restore the original object, before using DeleteObject().
|

But this issue is not due to that. Even if we just create a brush and delete it very next, this issue exists.

hi
since when Apply is clicked in a property sheet, its OnAplly() calls updateData() for the active page and initializes an ELLPROP structure with the settings, then sends a message to the main window containing the structures address.The main Window forwads the massage to the view (so far so good),the view copies the property values to its own data members (comes the problem) -suppopse i have many property sheets,each one will have an OnApply() that will fill the ELLPROP Structure with its own values, the mainframe will handle OnApply Once like this
LRESULT CMainFrame::OnAplly(WPARAM wParam,LPARAM lParam)
{
m_wndView.SendMessage(WM_USER_APPLY,wParam,lParam);
return 0;
}
then the view also will handle it once
..view::OnAplly(WPARAM wParam,LPARAM lParam)
{
ELLPROP* pep = (ELLPROP*)lParam;
// my question what do i do here (if am supposed to do it only here) if i have multiple property sheets
//  lemmi give an example i may think of using proprty sheets insead of very many dialog boxes to write a simple school management program.
so one property sheet be for registration (first page studets reg, 2nd page staff reg,3rd page, members reg ..), another property sheet will be for finance (1st page setting the fees charges,2nd page payment of fees, 3rd page payment os salaries and wages to workers, 4th page payment of bills ..)
know i want each to update a database using ADO so each property page will have to open an appropriate recordset and do that(i havent tried the database part and know whether it will bring problems too),what i have tried is to have all the input values sent to the view so that i can display them in the client area and i dont know how the view's member variables will copy all these values that are coming from different property sheets and each sending an ELLPROP structure..(should i have some kind of control to know that this structure is from the finance sheet so just copy the finance deatils and leave the registration details- and if so how do i control that)
.......
.....
}
am new to MFC (4 mths know) so please if you can give me more deatils i'll rilly appreciate,thanks.

This is a flaw in your design: The document should hold the connection to the database, and the views (a property sheet is a view) access the property sheet.
This holds true even if your application does not use MFC Doc/View.
This paradigma is called model/view/controller and is independent of the toolkit used. You just might have to code more yourself.

Are you sending the styles too through the network? I think you r sending plain text message only through the network to the other client. If so you must send the styles too, in some format along with the message text and then use this style at the other end's to display it.

hai Ktm Techman,
Yes, Ur correct...I am sending the plain text only, But How to send the font styles also.How can I send Font styles ? Whether any API is there....or If you know any examples code pls send it to me.....
