What is the maximum size of a combo box. How many entries can i have in a combo box?

toxcct2-May-07 0:56

looking at the index types, i'd say the maximum an int can store...

why are you worry about ?

Can i add a thousand strings into a combo box? Is there a limit to the data that can be stored in the combo box?

toxcct2-May-07 2:27

even if you're on a 16 bits environment, an int can store (2^16)/2 == 32768...
so, think of what you can store on a 64 bits system... Poke tongue | ;-P

but hey !! you didn't answered my questions ! Suspicious | :suss:

I have a database for face recognition and speaker recognition. So i wanted to know the maximum number of people i can have in the database if i display all the names in the combo box

I added 65535 string into the combo box and it works fine.. Thank you

toxcct2-May-07 2:38

2-May-07 2:38

hey, hear me well. i didn't say the size limit was 65536 either !

but is it that good to put all that strings in a only combobox ? wouldn't it be better to use a CListCtrl for instance ?

Just who is going to have enough patience to scroll through that sea of names?

I agreee toxcct CListBox is better than CComboBox for your program of course if you want to show data to user .

A cast is not appropriate in your context?

I am using ShellExecute command to open a batch file but I have to capture the display when the batch file is open. Is this possible in VC++.

ShellExecute(m_hWnd,"open","Yamini.bat",NULL,NULL,SW_SHOWNORMAL);

After executing this command I have to capture the display in the screen so that I can use it later in my code

you mean, using the image, of the text output ?

what exactly are you trying to do here ?

can't you just put a pause at the end of the .bat, and manually select the text to copy if that's what you're after ?
