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"));
}

it works,
but i really cannot see what is the difference between your method and mine~
Can explain a little bit~?
Thanks

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.  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  ?

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

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

Microsoft SOAP Toolkit 3.0 isn't suitable for such task

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.

after I compile my programme, my programme got a lot of error and most of the error are almost the same. And I not understand the error can somebody tell me...
myExceptionTester.obj : error LNK2005: _main already defined in myClient.obj
myExceptionTester.obj : error LNK2005: "class myLog winLog" (?winLog@@3VmyLog@@A) already defined in myClient.obj
myHostInfoTester.obj : error LNK2005: _main already defined in myClient.obj
myHostInfoTester.obj : error LNK2005: "class myLog winLog" (?winLog@@3VmyLog@@A) already defined in myClient.obj
myLogTester.obj : error LNK2005: _main already defined in myClient.obj

The libraries you are linking (myExceptionTester, myHostInfoTester + myLogTester) probably already have a 'main' function. Check your libraries and remove the 'main' functions. You don't need these anyway, since these are libraries, which are used in other applications.

what is unresolved external symbol "public: __thiscall...
|
|
|
|
|
what do you think it is ?
unresolved external symbol means that the linker was looking for an external symbol (defined outside the .c/.cpp file) but could not find it...
you are missing some lib files...

I was wondering if anyone knows how the string returned in the OPENFILENAME-lpstrFile is returned? is it ASCII? UNICODE?
|
|
|
|
|
I think it's ASCII. That's what a lpstr is, isn't it ? Did you think to run it and see ?

Hi!
Can someone help me convert the following VB code to VC++?
---------------------------------------------------------------------
Const LOAD_FIRST = 2
Const LOAD_NEXT = 3
Dim ret As Long
Dim obj As String
Dim func As String
Dim sw As Long
sw = LOAD_FIRST
obj = “main”
Do
ret = pd.sym_get_ func func_name(obj, _func, sw)
If ret = 0 Then
Exit Do
Else
MsgBox func
sw = LOAD_NEXT
End If
Loop
---------------------------------------------------------------------
Thanks a lot! 
Please help..
