EnumServiceStatus would be best thing.
you can also use CreateToolhelp32Snapshot as an alternative

You should be able to use the SERVICE_CONTROL_INTERROGATE control code.

Problem with string table

I have a problem when add a string into string table with ID bigger than 61446.
For example: in resource.h:
#define IDS_STRING_TEST 61446
When I build WIN32 Dynamic Link Library (VC++ 6.0), I get the following error:
C:\Program Files\Microsoft Visual Studio\VC98\MFC\INCLUDE/afxres.rc (120): error RC2151 : cannot reuse string constants, 61446(0xF006) - "Test" already defined. Cannot add 61446(0xF006) - "an unnamed file".
But when I build a Dialog-Based Application, it's ok
Could any one tell me why?
Thank in advance.

You would have a problem if you define it not bigger than 61446, but equal to 61146 or anything else that is already in use. Even 61147 or 61145 should work! So use the values that are not already being used.

61446 = 0xF006 and this is defined as AFX_IDS_UNNAMED_FILE with the description "an unnamed file" in the file AFXRES.RC

Getting the Combo Box selected item using Win32 API.

Suresh H16-Jan-07 19:36

Re: Getting the Combo Box selected item using Win32 API.

16-Jan-07 19:36

Hello All,

I am adding values 0,1,2 to a combo box in Initdialog

switch(Message)<br />
{<br />
case WM_INITDIALOG:<br />
{<br />
HWND hwndCombo = GetDlgItem(hwnd, IDC_CB);<br />
SendMessage(hwndCombo , CB_ADDSTRING,0, (LPARAM) "0");<br />
SendMessage(hwndCombo , CB_ADDSTRING,0, (LPARAM) "1");<br />
SendMessage(hwndCombo , CB_ADDSTRING,0, (LPARAM) "2");<br />
}

in other function I want to use the value of the combo box, (user selected item) for that I am using below code

int F;<br />
HWND HCBF = GetDlgItem(hwnd, IDC_CB);<br />
SendMessage(HCBF , CB_GETITEMDATA,(WPARAM)F, 0);

This code has no error but I am getting some junk value and i am not geting the values 0,1,2
Can u please tell me what is the error in the above code ???

Thanking you,

Suresh HC.

Here , you have not initialized F.
Passing junk values as index. Pass index you want there.

CB_GETITEMDATA is not right message to send in this case, too.
You need to use CB_GETLBTEXT.

Hi Prasad,

Actually I want to extract the value of the Combo Box (user selected value)
In combo box we have values from 0,1,2,3 ---- so on when user selects some value fro list any number , I want to extract that number and I want to use that number in the program.
Can u please tell me what I have to do ??

Re: Getting the Combo Box selected item using Win32 API.

You must use of CB_GETCURSEL for get index to currently selected item instead use of 0

Re: Getting the Combo Box selected item using Win32 API.

This code should suffice,

int nIndx =::SendMessage(hCombo,CB_GETCURSEL,0,0);
TCHAR buff[100];
::SendMessage(h,CB_GETLBTEXT,(WPARAM)nIndx,(LPARAM)buff);
//buff will contain text returned

And also one other thing if he wants to use CB_GETCURSEL(return values) for works on his programs(not for combobox)its not good idea because it returns -1,0,1,...but if he has values like 100,200,300 on his combobox... return values of CB_GETCURSEL not helpfuls Wink | ;)

Thanks Prasad Code is working.

Thanks for taking some time for me and helping me.

In yr code 1st line was enough for me

int nIndx =::SendMessage(hCombo,CB_GETCURSEL,0,0);

since in the combo box I have values from 0,1,2,3,4,5 and so on …
so as I get the Index number value will be the same as the CB content.
I did not know about the CB index. Thank you very much. Smile | :)

Seems very strange logic.
But, use CB_GETLBTEXT message, as it will not be the case always.
