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,
C++/MFC; Visual Studio 6.0

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

UNLEASH THE TOKENIZER!!!
Aye, Captain!

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().

why on earth do you want to do such a thing ?

i still don't understand why he would want to close stdandard stream for this...
|
|
|
|

you right,
lame and oggenc are during stream encoding using stdin
and i dont know how to let them know that no more data is comming.

What are those programs expecting as a "termination" character?

i dont know, this programs doesn't say
it is maybe simple and obvious but i have no idea how to use it for stream
processing.
...and data are raw PCM data (wav audio) and there is probably no
chance to say "this character" means end.

i really don't understand how code finds correct VTable(not function)
I read here : http://www.parashift.com/c++-faq-lite/virtual-functions.html#faq-20.4
ıt says:"The idea is to change each Der object's v-pointer so it points at its class's v-table. (This is not a second v-pointer; it's the same v-pointer that was defined in the base class, Base; remember, the compiler does not repeat step #2 in class Der"
I confused here.
How many are vtables created?
amount of base+derived class.One VTABLE for each.But all of them has one VPTR.IS this right?
So if there is a VTABLE for each class but one VPTR; How can code find the correct function?
I know calling virtual func. means calling an offset.But this offset is in the class's VTABLE.But first it must find one more offset that indicate correct class?
Am i wrong?
For example i have one base class and one virtual funct. and three derived class in a dll.Here when i call to 3. derived class virtual function from base class pointer from my exe.Here first it must find 3. VTABLE and and first offset.Right?
But here we have only one VPTR so haw can it find 3. VTABLE and then offset of the function?
I am looking for your answers
Thanks.
