I just installed the VS .NET 2005 Professional and the accompanied MSDN library in FULL. I am using them for a VC++ project and am having trouble with the local Help functionality: F1 help is broken. That is, if I position the cursor over a keyword (for example OnEraseBkgnd) and hit F1, it always displays the topic-not-found page.
Any suggestions appreciated.

Check your Help settings: Tools->Options, Environment->Help->Online
Try setting it to "Try local first, then online" and see if that works.

I have tried that. The real issue is that sometimes the F1 help works, sometimes not. Any idea?

using the following, the XML is saved as a single line in the file, and when loaded in either notepad
or VC6, it shows on one line :
MSXML2::IXMLDOMDocument2Ptr pXMLDoc;
pXMLDoc->save( path );
Is there a way to have some line-feed/carriage return so that the text XML is "well formatted" or at least better formatted so that it can be viewed in notepad ?
Thanks.

The only thing like that I know of is the preserveWhiteSpace property of the DOMDocument object. But I don't think that has any effect if you create a new file from scratch, only if you load and modify an existing file.

Hello folks,
I trying to instatiate a activex control, print template from Internet Explorer. The argv[1] parameter it's a path string to a HTML file(like these: c:\MyTemplate.htm). But it seems the type of vTemplatePath don't match and an exception is launched:
Error on line 474 atlbase.h
Expression: p!=0
I'm sorry to post this question here, but I'm a noob in C++. I'm a web programer(PHP, javascript, action script II), and I need very much of this.
Someone can help me to solve this?
Thanks a lot!

What was the particular string being passed? Formatting, spaces, backslashes can all affect it.

Hi,
I've got a problm with the datagrid. I've changed the datasource of my datagrid to a dataview in order to control this new row that is created when switching between readonly true to false. I am controlling the readonly toggle via a button on the same form. This works fine if I don't touch the datagrid prior to switching the readonly status. However once I have selected a cell in the datagrid and then change the status, it seems like the entire datagrid freezes and I can't do anything.
Any suggestions?
Thanks
David

I need some help in writing an OPC server. The ideea is that i don't really need to write an OPC server but rather something wich acts as an OPC server. There is an application (that's already running) which is an opc client and i need to add some new data to it. My ideea is to write my own OPC server(simulation ) wich connects to a database at one end and provides the access to the data that the existing application needs at the other end.
I know that what i need is not really an opc server and i have already read the few articles that were posted here (which were of great help in getting closer to my solution) but i really need a few advices on were to go to from here.
Thanks.

hi eusto
i am also working on the OPC server/client application though without database.
you can download the OPC client and server code from (the one from Metadynamics is good one)
http://www.opcconnect.com/source.php[^]
But in the client side code provided he used ATL object which i am not able to figure it out...if u find it ...plz help

Well..for the server part there is only LightOpc which...well..only provides russian language support and i spent the last day trying to figure things out. I'll get back to you on the client side problem when i get around to it

No...you can donwload the sample code for both server and client (either in VC++ or VB) from Metadynamics website ..check the link posted above for the toolkits.

Okay so I created a dialog box with a List Control in it. I am trying to
get the index of the current item selected in order to retrieve the text and
use it in a map. I found examples here but for some reason I am not getting
an index number back. All I get is 0.
Heres the code:
<br />
std::map<std::string, int>mpCalibrations;<br />
<br />
********<br />
<br />
for(i=0;i<=74;i++){<br />
LvItem.iItem=i;<br />
LvItem.iSubItem=1;<br />
sprintf(Temp,"%d",mpCalibrations[calibrate_list[i]]);<br />
LvItem.pszText=Temp;<br />
SendMessage(hList,LVM_SETITEM,0,(LPARAM)&LvItem); <br />
<br />
<br />
case WM_NOTIFY:{<br />
switch(LOWORD(wParam)){<br />
case IDC_LIST2:{<br />
int iSlected=0;<br />
int lResult=0;<br />
if(((LPNMHDR)lParam)->code == NM_CLICK){<br />
iSlected=SendMessage(hList,LVM_GETNEXTITEM,-1,LVNI_FOCUSED);<br />
Please help..
TY

How about:
int nItem = SendMessage(hList, LVM_GETNEXTITEM, -1, LVNI_SELECTED);
assert(nItem >= 0);
LVITEM lvi = {0};
char szTemp[128];
lvi.mask = LVIF_TEXT;
lvi.pszText = szTemp;
lvi.cchTextMax = sizeof(szTemp);
SendMessage(hList, LVM_GETITEMTEXT, nItem, (LPARAM) &lvi);

Well, I still got a 0 back for nItem. I cannot see what the problem is.
Any other ideas???
|
|
|
|
|
At the time this code is executed, is there a selected item in the control?

In debug mode(.NET), the value remains 0. Furthermore, I initialized the
value to 5 and it is being SET to 0. The final app, will allow you to select
an item and via the map, display the corresponding value in an EditBox for
modifying. I added this code to confirm that I'm getting 0 no matter what
I select.
The map is filled w/ random numbers for now.
<br />
if(((LPNMHDR)lParam)->code == NM_CLICK){<br />
int nItem = SendMessage(hList, <br />
LVM_GETNEXTITEM, <br />
-1, <br />
LVNI_SELECTED);<br />
SendMessage(hList, <br />
LVM_GETITEMTEXT, <br />
nItem, <br />
(LPARAM) &lvi);:confused:<br />
itoa(nItem,buffer,4);<br />
SetWindowText(hwndEdit,buffer);<br />
}

When you click a button to execute this code snippet, the list control will lose focus, and perhaps deselect any items that had been selected. Does the control have the LVS_SHOWSELALWAYS style?
What does this return:
int nCount = SendMessage(hList, LVM_GETSELECTEDCOUNT, 0, 0); Remember that items in the control are 0-based.

Getting back 0 from LVM_GETNEXTITEM is a valid return, not an error return; -1 is an error return (or "not items found"). Getting back 0 indicates that the first (zero-ith) item in the control is selected.
Calling SendMessage again with the same parameters will return zero again because you are still specifying -1 for the "start" of the search.
Peace!

A bit more code:
<br />
case WM_INITDIALOG:{<br />
HWND hList=GetDlgItem(hwnd,IDC_LIST2);<br />
SendMessage(hList,<br />
LVM_SETEXTENDEDLISTVIEWSTYLE,<br />
0,<br />
LVS_EX_FULLROWSELECT | LVS_SHOWSELALWAYS); <br />
Well David, I tried this snippet and a big fat 0. I initialized it to 500.
<br />
nCount = SendMessage(hList, LVM_GETSELECTEDCOUNT, 0, 0);<br />
itoa(nCount,buffer,10);<br />
SetWindowText(hwndEdit,buffer);<br />
James, my understanding is the above "SendMessage" will return the index
of the item selected. I'm selecting in the middle of my 75 item list.
Shouldn't it return a value the same as "GETCURSEL" does for a listbox???
This was so easy with a regular ListBox.(ughhhh)
I'm probably gonna be beating my head against the wall once the solution is
discovered. Something simple I'm sure...
