It is possible to avoid that a program executes from our own application?
An example:
I'm running my app and I don't want to let notepad.exe to execute.
Is this possible?
Thanks in advance.

Just out of curiosity, why?

just don't call it !
why would it open otherwise ?

Can you explain why you dont want?
|

The question is that 2 programs are really time consuming exigents.
The point is don't let the user execute both at the same time.
Then , if one is running don't let run the other and viceversa.

hi all,
i m using spamassassin to filter my mails as spam or not, but i m unable to execute spamassassin.exe,it works fine when i call that exe from DOS(command prompt)with same commandline argument, here is the code i m using,
C++
HINSTANCE hins =::ShellExecute(NULL,"open","F:/sa/spamassassin.exe","<F:/spam.txt> F:/spamT.txt",NULL,SW_HIDE); in this situation exe invoke and then disappear without executing as i seen tha through task manager, when i call above line of code behind a button then process increases in task manager and then it decreases, without full execution.
here is the command which i paste on DOS and works fine,
any idea.
C:\Documents and Settings\tasleemarif>F:/sa/spamassassin.exe <F:/spam.txt> F:/spamT.txt"
i have also tried that using C++ spawn functions as well but did not work too. any idea r any person can guide me how had worked on spamassisn.
Regards.

The code you've shown seems fine. Temporarily change SW_HIDE to SW_SHOW. Does that produce any windows?

system(cmd);<br />

What does this do:
ShellExecute(NULL, _T("open"), _T("c:\\windows\\system32\\notepad.exe"), _T("c:\\boot.ini"), NULL, SW_SHOW);

Ok, so what happens if you change the third and fourth arguments?

Hi,
I'm facing an annoying problem while using a list control.
In my project,I have a list control which I need to update every 250msec(the list of items is
a dynamic list).
In order to update the list control, I delete all of the items in the list control and insert the new items to the list.
As a result,the list control is blinking.
I'm using the following peace of code
m_list.SetRedraw(FALSE);
m_list.deleteAllItems();
for(int nIndex = 0 ; nIndex < ItemsList.GetSize() ; nIndex++)
{
m_list.InsertItem(nIndex , _T(""));
m_list.SetItem(nIndex , 0 , ItemsList.RemoveHead().GetName());
m_list.SetItem(nIndex , 0 , ItemsList.RemoveHead().GetIP());
}
m_list.SetRedraw(TRUE);
I tried to pdause LockWindowUpdate() and UnlockWindowUpdate() instead of SetRedraw()
but the items continue to blink.
Is there a better way to update the list without blinking???
HELP!!!!!
With bes regards,
Eli

Hello,
Maybe you need to create a method that compares and changes only what needs to change.
This soluction will gibe you problems if the number of items incrise.
populating ListCtrls and ListBoxes are expensive, and will be very slow if the number of item incrise.
|

As Max mentioned, populating list view controls is expensive.
Even more so the way you are adding items - 3 updates for each item.
If you use a "virtual list-view" (one that has the LVS_OWNERDATA style) then you can store each
item's info in a collection of some kind and do all your processing in the background.
The only time the list view has to change is when items are added or removed (so the total number
of items in the control is always the same as the number of items in the collection).
After each update of the contents, just a repaint of the control would be necessary.

Hi Mark,

In order to do so,I need to search if the current items in the collection exists in the list ctrl,and this is not something that we want to do(we don't
want that the list control will have to know what kind of items it "holds"...).
Anyway,Thanks for your reply,
With best regards,
Eli

I'm not sure you understood what I meant.
In a virtual list control, you store everything about the items somewhere else. The control
keeps index and state information only. When the control needs to draw it sends a notification
requesting the text for each item and subitem. From the looks of your sample code, you already
have that information in a list container, so there's no reason to store it in the control as well
(like you are doing now).

Hi all,
I'm using the "CIniFile Class for C++ - A robust cross platform INI file class" wrote by Todd Davis and it's working and all but for some or other reason I keep getting garbage in the ini file. For example:
ç[TEST]
ÿMyKey=MyValue
Can anyone help ??
Thanks

Doubtful, since you've not provided anything useful.

Right ... So write the following lines of code:
CIniFile IniFile;
IniFile.Create("test.ini");
IniFile.SetValue("MyKey","MyValue","MySection",FileName);
And when I open the ini file I have garbage in the file. I haven't edited the .cpp and .h files provided by the article.
Useful enough ??

Have you made any other changes (besides here) to the CIniFile class?
Have you stepped into the SetValue() method?

No I haven't made any changes, the only 'thing' that differs is my IDE. I'm trying to use it in C++ Builder 2006. But I can't see anything wrong with that (besides that Builder suck). Yes I have stepped into SetValues, but I'm struggling to debug ... not use to Borland debugging environment.
Oh well, I'm sure I'll figure it out ...
Thanks David

have you tried compiling in both UNICODE and non-UNICODE to see if that matters ?

I would like to create an application which is basically a transparent window, or something similar, which has "objects" on it, which are images which can be dragged around the screen, and clicked on, and double clicked on etc... However, I am not sure how to implement this..
I usually work in pure C/C++ however if there are some C++ classes which allow for this i would be willing to try them out..
Thanks for your help!
