I'v deefined my own font for CTreeView, but have one problem. Not all words displays in tree branches. I mean, when I enter text in tree branche "Some text", in CTreeView it displays as "Some t".
So, I want to determine size in chars for tree branche to display all words completely.
Thanks in advance, bilas.

make sure you've defined a TVINSERTSTRUCT struct like here..

TVINSERTSTRUCT tvis = { 0 };<br />
<br />
tvis.item.mask = TVIF_TEXT | TVIF_CHILDREN;<br />
tvis.item.cChildren = 1;<br />
tvis.item.pszText = "name";<br />
tvis.item.cchTextMax = lstrlen(tvis.item.pszText);<br />

Yeah, you are rigt. But I need to set cchTextMax every time, when branche is renamed. I'll try again. Anyway, thanks a lot, bilas.

I've not tried it, but I would suspect Automation would be what you want. You might also look to see if PowerPoint has an ActiveX control.

Hitting allmenu items of an launched application

Vaibhav Sanghavi7-Feb-05 23:03

Hi All,

I have launched an application programmatically. I want to browse and hit all menu items of that application programmatically. How do I do that?

I have pointer to the mainframe window of that launched application. So from that I can get CMenu pointer to its menu using CWnd::GetMenu() fuction.

So now I have CMenu* which points to the menu of launched application. I am using CMenu::GetDefaultItem() to get the identifier and then hitting the menu using SendMessage but nothing is hapening. Any idea? Here is the code..

m_pMenu = m_pMainFrame->GetMenu(); // m_pMenu is of CMenu* type
UINT uItem = m_pMenu->GetDefaultItem(GMDI_GOINTOPOPUPS);
WPARAM wParam = MAKEWPARAM(0,uItem);
int iRet = m_pMainWnd->SendMessage(WM_COMMAND,wParam,NULL);

Do you see anything wrong in above code?

The other approach I adopted was as per below which just iterates though all menu items just to check that if I am able to access all menu items or not..

m_pMenu = m_pMainFrame->GetMenu();
UINT uItem = m_pMenu->GetMenuItemCount();
CString str;
for(int iPos=0; iPos < uItem; iPos++)
{
m_pMenu->GetMenuString(iPos,str,MF_BYCOMMAND);
}

Unfortunately this approach is not at all accurate. For instance If I launch Notepad.exe for then It gives me uItem = 4. But when I browse to get the menu string of each of them. It gives me blank as a string for Ipos= 0, gives Save when ipos=1, Save As for iPos= 2 and &Find for iPos = 3; This is an unexpected result because Save and Save As is part of File menu but Find is in the Edit menu.

Any clue?

Hi Thanks but the function IsNetworkAlive() works only for TCP/IP connection, but my machine can be on IPX/SPX isn't there any generic function call which could tell me if my machine is on any type of LAN.

Thanks n Regards.

Have a look at CWnd::EnableTooltips[^]

There is an example there. A little bit of work is necessary in order to show the appropriate list item data.

Hi,

I have written a C code of an encryption algorithm. How do I measure the number of cycles of my implementation? Hope to get some feedbacks/suggestion from the forum members, or can email the feedbacks to my email address watija@yahoo.com.

just put a Counter(an unsigned int or long or anthing like that) in your Cycling Function( Big Grin | :-D

) i.e. encryption algorithm.

and every time the Encryption Algorithm make a cycle, increment the Counter by one, and when your cycling function end, you will get number of cycles in the Counter

if you want to count the CPU cycles, you must set up a highperformance timer.
check out the articles on timers here on CP.

if you want to know CPU cycles (ex. "it takes X cycles to do one round"), you'll have to analyze a machine-language implementation of your algorithm.
