Why not? It's in the PROCESS_INFORMATION structure that ShellExecute() populates.

Thank you very much

I did the same but bit differently. I used CreateProcess() and in that there is last parameter as [out] parameter which is PROCESS_INFORMATION structure and I use that to close application.

thankx once again

I'm glad you figured it out because my suggestion was wrong. I meant to say CreateProcess() not ShellExecute().

You can get some of the properties using GetSystemMetrics().

SM_CMOUSEBUTTONS will get you the number of buttons.
SM_MOUSEWHEELPRESENT will tell you if it has a wheel.
SM_SWAPBUTTON will tell you if they swapped their buttons (left handed).

the BITMAPINFOHEADER struct at the beginning of the BMP has DPI members. set them with the values you want.

Problem with list control

I am declaring a list and add in contents into it~
But i am always unpredictably facing the display problem~
For example, i am reading information from a database entry by entry, but what is displayed in the list control is totally out of order, and correspondance is wrong. what is worse, some of the colums are blank though i can see the entries are correctly inserted into the list(i have traced this using break point).

The code i used is as below:

(m_bList is the list control declared)

int index;<br />
for(index = 0; index < total; index++)<br />
{<br />
LV_ITEM lvi;<br />
lvi.mask = LVIF_TEXT;<br />
<br />
lvi.iItem = index;<br />
lvi.iSubItem = 0;<br />
lvi.pszText = (LPSTR)(LPCSTR)sbatchid;<br />
lvi.lParam = 1;<br />
m_bList.InsertItem(&lvi);	<br />
<br />
lvi.iSubItem = 1;<br />
lvi.pszText = (LPSTR)(LPCSTR)page;m_bList.SetItem(&lvi);<br />
		<br />
CString modi = time.Format("%Y/%m/%d/%H:%M");<br />
<br />
lvi.iSubItem = 2;<br />
lvi.pszText = (LPSTR)(LPCSTR)modi;<br />
m_bList.SetItem(&lvi);<br />
}

First thought (without reading your code) have you disabled the "Sorted" option of the list control ?

Second thought, after reading the code :

It is a safe thing to zero the LVITEM struct (you wrote LV_ITEM, but it is in fact LVITEM) before using it.

LVITEM lvi;
ZeroMemory(&lvi,sizeof(lvi));

It is also not a bad idea to check for the result of the InsertItem and SetItem functions before going on.

Last thing to do is maybe to prevent updating the control before it is entirely full, or use virtual list if you are dealing with database entries (search on Code Project for virtual lists).

But the code seems OK to my point of view. You should really check that the Sort ComboBox in the Properties of the control is set on "None" (in the VC++ Dialog Editor). Or programatically unset the LVS_SORTASCENDING and LVS_SORTDESCENDING window styles of the control.

Thanks for your reply first~
I have checked the sort combobox, unfortunately it is set to none.

For the result of insertitem, it is always returning 0 which seems to be fine~
and the setitem function is returning 1 for successful.

And how should i use zeromemory function, since it seems to be deleting the LVITEM and all the items are failed to be displayed in the list~

For initialisation of your lvi variable. Use it just once, after the variable definition:

LVITEM lvi;
ZeroMemory(&lvi,sizeof(lvi));

Now you can use lvi safely.

How about:

for (int index = 0; index < total; index++)
{
    int item = m_bList.InsertItem(index, 0, sbatchid);
    m_bList.SetItemText(item, 1, page);
    m_bList.SetItemText(item, 2, time.Format("%Y/%m/%d/%H:%M"));
}

Can explain a little bit~?

I think the difference is that David uses the index returned by InsertItem to access the associated subitems, whereas you use the loop index, which is then not necessarily equal to the inserted Item index. D'Oh! | :doh:

Meaning if loop index is 3, and inserted Item gets index 2, you will then modify subitem of Item with index 3 instead of 2. Is this clear Unsure | :~

Yes, use the w* classes. In your case std::wcout.

Creation DIME-envelope in C++

I need implement creation DIME-envelope in C++. And, conversely, I must restore source attachments from this DIME-envelope. I don't need implement sending or receiving data, only creation/parsing DIME-envelope.

What tools can I use for this? I think that this problem is typical and must be typical solution too. Can you help me, please?

May be Microsoft SOAP Toolkit 3.0 is suitable for this? And I found gSOAP Toolkit http://prdownloads.sourceforge.net/gsoap2, but I think that it
is very complicated and cumbersome for my simple task.

Thanks very mach

You can make an entry in the Software/Microsoft/Windows/CurrentVersion/Run registry or just create a shortcut to your program in the startup folder.
