>>Do I still need to close the file first?
Looks like it, unfortunately. Even ReOpenFile won't let you change the sharing mode without
closing the handle first. At least that's what I gathered from the SDK.
I'd say closing and reopening is the only way to go ... I may be wrong

Need to know if I can directly access elements in an STL array based on the Iterator ..
As for eg
List contains { 1,2,3,4,5,6,7,8 }
if List::Iterator iter = List.begin()
Now to access nth element can the routine be like
int GetElementAt( int index)
{
// range check
iter = List.begin();
iter+=index;
return *iter ;
}

A std::list isn't an "array" and list iterators don't support random access. Vector and deque iterators support the += operator.

try
std::advance(iter, index);
Might work

will
for(int i=0;i<index;i++,iter++) ;
this="" should="" work="" as="" the="" ++="" operator="" is="" supported="" for="" iterator="" ?=""

yes the ++ operator should be supported for the iterator
I sugest you look at the doco

Hi fellows. I created an app that have 2 menus. The code for these menus are below:
<br />
hMenu1 = CreateMenu();<br />
hMenu2 = CreateMenu();<br />
hSubMenu1 = CreateMenu();<br />
hSubMenu2 = CreateMenu();<br />
unsigned int uiParams[5];<br />
unsigned int uiNums[5];<br />
unsigned int uiSize = 5;<br />
char cNames[][256] = {"&Menu", "&Estudo Anatômico", "M&odelo com Transparência", "", "&Sair"};<br />
uiParams[0] = MF_STRING|MF_POPUP;<br />
uiParams[1] = uiParams[2] = uiParams[4] = MF_STRING;<br />
uiParams[3] = MF_SEPARATOR;<br />
uiNums[0] = 0; uiNums[1] = 1; uiNums[2] = 2; uiNums[3] = 3; uiNums[4] = 4;<br />
MenuCreator(hMenu1, hSubMenu1, uiParams, uiNums, cNames, uiSize);<br />
SetMenu(hwnd, hMenu1);<br />
DrawMenuBar(hwnd);<br />
char cNames2[][256] = {"&Controles", "&Habilitar/Desabilitar Controles"};<br />
uiParams[0] = MF_STRING|MF_POPUP; uiParams[1] = MF_STRING;<br />
uiNums[0] = 5; uiNums[1] = 6;<br />
uiSize = 2;<br />
MenuCreator(hMenu2, hSubMenu2, uiParams, uiNums, cNames2, uiSize);<br />
SetMenu(hwnd, hMenu2);<br />
I have a function that create menus dynamically. Here it is:
<br />
void MenuCreator(HMENU hParentMenu, HMENU hChildMenu, unsigned int uiBehaviors[], unsigned int uiIDItems[], char cNameItems[][256], unsigned int uiSize)<br />
{<br />
if(hParentMenu == NULL || (hParentMenu == NULL && hChildMenu != NULL))<br />
{<br />
MessageBox(NULL, "Menu pai não pode ser nulo", "Erro", MB_OK|MB_ICONERROR);<br />
return;<br />
}<br />
if(hParentMenu != NULL && hChildMenu != NULL)<br />
{<br />
for(int i = 1 ; i < uiSize ; i++)AppendMenu(hChildMenu, uiBehaviors[i], uiIDItems[i], cNameItems[i]);<br />
AppendMenu(hParentMenu, uiBehaviors[0], (unsigned int)hChildMenu, cNameItems[0]);<br />
return;<br />
}<br />
if(hParentMenu != NULL && hChildMenu == NULL)<br />
{<br />
for(int i = 0 ; i < uiSize ; i++)<br />
{<br />
AppendMenu(hChildMenu, uiBehaviors[i], uiIDItems[i], cNameItems[i]);<br />
}<br />
return;<br />
}<br />
}<br />
when I insert the first menu, works fine. When I insert the other, the first menu isn't there, just the second. What I want to do is to have 2 or more menus at the same time, like File|Edit|View.
What's going on? Thanks
|
|
|
|
|
Problem solved, I was create 2 main menus. So, when I insert the other main menu it was overlapping the other. I deleted the other main menu and add the items in only 1 main menu
|
|
|
|
|
The application must call the "DrawMenuBar" function whenever a menu changes, whether or not the menu is in a displayed window.

Hi I have a CSV (Comma Separated Value) file that I need to read in and put data into structures. I am going to be using MFC to have a gui to select a file and read it. I'm more interested in getting to open a csv file and parsing the data. Each like in the csv file will have around 10 items or so....
I just would like to know the syntax of how to go about doing this...
Any help would be greatly apperciated....
Thanks,

Read the file line by line.
Then, on each line, unleash a tokenizer: The boost one[^]comes to mind.

UNLEASH THE TOKENIZER!!!

Hmm - so my intended joke did not come through. 
I always thought "unleash" has a meaning along the lines of "let loose onto", "expose someone to it".
Instead, it seems to be sailor-slag for "untie a rope"

No No... the joke DID come through. I actually sprayed coffee on my moniter when I read it haha.
I liked it! I just took it even further.

For each line read from the file, you can use AfxExtractSubString().
