There's more than one way to skin a cat. Are you supposed to use C streams (e.g., FILE*), STL streams (e.g., ifstream), MFC (e.g., CFile), or what?

consider
char *buff[] = { "sec1",
"sec2",
"sec3",
"sec4",
"sec5"
};
I want to pass this to the client side from my COM server
Server side code
VARIANT msg ; <br />
char **buff ; <br />
buff = new char*[5];<br />
for(int i=0;i<5;i++){<br />
buff[i] = new char[32];<br />
memset(buff[i],0,32);<br />
char str[5];<br />
sprintf(str,"Sec%d",i);<br />
strcpy(buff[i],str);<br />
}<br />
SAFEARRAY sArray ;<br />
sArray.cDims=2 ; <br />
sArray.fFeatures=FADF_AUTO ;<br />
sArray.cbElements=1;<br />
sArray.cLocks=0;<br />
sArray.rgsabound[0].cElements=5;<br />
sArray.rgsabound[0].lLbound = 0;<br />
<br />
sArray.rgsabound[1].cElements=32;<br />
sArray.rgsabound[1].lLbound = 0;<br />
sArray.pvData=(void *)(buff);<br />
msg.parray=&sArray ;<br />
msg.vt=VT_ARRAY | VT_UI1;<br />
_bstr_t t("Dummy");<br />
dummy->Fire_ProjectEepromMsgEvent(t,msg);<br />
for(i=0;i<5;i++){<br />
delete [] buff[i];<br />
buff[i]=0;<br />
}<br />
delete [] buff ;
On the client side the handler has the following signature
static _ATL_FUNC_INFO MsgInfo = { CC_STDCALL, VT_EMPTY,2,{VT_BSTR,VT_VARIANT }<br />
<br />
HRESULT CClient::HandleMsgEvent(BSTR Name,VARIANT data )<br />
{<br />
SAFEARRAY *sa ;<br />
sa = data.parray;<br />
<br />
}
For some reason I am unable to get this value in the client .
Please help

the _CRTDbg macros can be used to view the contents of the heap.. in context of the current process... that is the heap used by our program... what if i want to view the contents of the heap of another executing process?

Hello everyone, plz help me with the following problems:
The environment is Windows.
I want to let my program stand behind an executing program in the hook chain, so my idea is like this:
-force that program, say A, to stop.
-start my program .
-start A again.
With that approach I need to solve the following sub problems:
1. How to stop an executing program ? I guess I have to create fake messages to send to the program, but I still don't know the specifics.
2. How to start the program again ? I guess I can keep the location of the exe file when I stopped it, then use that to launch it again.
Is there any better approach to do that ? or if you know the answers to the questions 1 or 2, plz let me know, I need help badly, thanks.

Is there a way to copy a MFC Dialog from one project to another in Visual Studio7.1? I am trying to bring in two Dialogs from another project, cutting and pasting does not do it...
|
|
|
|
|
i use vc 6:
in target project, open rc file of source project, then copy the dialog - hope it works in vc 7.
includeh10
|
|
|
|
|
Unfortunately, that does not work
|
|
|
|
|
did you close source project?
you do not need to open source project - copying is done only by target project - from rc file to target
includeh10
|
|
|
|
|
Close both the source and destination projects, then in a VS instance with no open project, open both the projects' *.rc files. You can then cut and paste correctly.

Hi,
I have this strange bug in my Visual Studio 6.0:
While editting, I cannot see the information regarding MFC objects. i.e. parameter info and complete word options don't work for Visual/MFC object (CString for example) and also I the member function data (return value and args) are not being displayed.
All of this works fine when refering to classes and objects which I wrote.
So to conclude it the problem is with displaying information of built-in classes.
I tried to reinstall Visual Studio and MSDN, but the problem was not solved, and this thing didn't happened to me with the same application and the same installation of VS and MSDN on other computer ... can it be something to do with my computer or the programs which are installed on it?
please help me out here.
thanks,
yaron.

Try this: Close VC, delete your project's .ncb file, and reopen the workspace. Deleting the .ncb file often fixes many IntelliSense problems.

i.e.
if user selects a directory and/or file (or multiple selections) in Windows explorer, i need to know these user selections when user clicks a button in my app - knowing selection by a click (WM_message), not monitor Exploere.
thanks

I'm a bit confused. What does Windows Explorer have to do with your app's response to a button-click?
Are you simply wanting to know what selection has been made within Windows Explorer? I'm not for sure, but I think that IPropertyNotifySink might be needed for this.

maybe my english is not good enough to ...
they are 2 things: just think about the app needs to know user selections by a button-click ---- button-click is not the same as monitoring all Explorer (use less CPU time?).
cheers

i simply checked IPropertyNotifySink - the function received notifications of changes (or monitor changes from my app's view), it is not my need.

If you want to query Windows Explorer yourself rather than have it notify you, you could use something like:
HWND hWnd = FindWindow("ExploreWClass", NULL);
if (NULL != hWnd)
hWnd = FindWindowEx(hWnd, NULL, "SHELLDLL_DefView", NULL);
if (NULL != hWnd)
hWnd = FindWindowEx(hWnd, NULL, "SysListView32", NULL);
if (NULL != hWnd)
{
CListView *p = (CListView *) CListView::FromHandle(hWnd);
if (NULL != p)
{
CListCtrl &c = p->GetListCtrl();
if ((GetWindowLong(c.GetSafeHwnd(), GWL_STYLE) & LVS_REPORT) == LVS_REPORT)
{
for (int x = 0, nItem = -1; x < c.GetSelectedCount(); x++)
{
nItem = c.GetNextItem(nItem, LVNI_SELECTED);
if (-1 != nItem)
TRACE("Item = %d\n", nItem);
}
}
}
}
