but i want put condition :don't read the spaces that in begin of lines
this problem appear with me now when i end my project

You cannot put a condition like that but remove space after reading a line. Look at trim left spaces in this[^] article.

thank you
functions in this articals was useful but when i try do the function ,apperar error on compile time say: #include "strutil.h" No such file or directory

hello
i used the function in that link and include the file (strutil)
but there is error as:
clear' : is not a member of 'basic_string<char,struct std::char_traits<char>,class std::allocator<char> >'
what can i do ?

What is Ordinal1028 and how to fix this problem

Possibly it is the ordinal number of the exported function inside the DLL.

Plesae guide me generally how we resolve ordinal problems.

Hi, this app is in C++ using Visual Studio 6.0, without MFC.
Basically I need to get the main menu of my application as an HMENU; this is the menu that has "File," "About," etc. The menu has a resource ID: IDC_MAINMENU.
GetDlgItem doesn't seem to work. GetSystemMenu is the wrong menu. Is there a way I can get the primary menu of my application by using a resource ID? If not, is there another way to do it?
Thanks!

Yay, that was easy. Thanks!

Like this:
m_menu=GetMenu();
m_menu=m_Menu->GetSubmenu(0);

Hi all,
This is a question of the form, "why do I type this" instead of "what do I type."
I'm importing some functions from local.dll. I've got a bunch of examples for doing this, and so I start writing these:
typedef int (*My_Function_Name_t)(int, int, char*, int);
typedef bool(*My_Next_Fxn_Name_t)(char**);
...
and then creating function pointers:
My_Function_Name_t My_Function_Name;
My_Next_Fxn_Name_t My_Next_Fxn_Name;
and then setting these to the functions in the dll:
My_Function_Name = (My_Function_Name_t)::GetProcAddress(localdll,"My_Function_Name");
...
Is this the only way to do this? Is there a better or newer way? I'd like to stick to C/C++ (not C# or .NET)

This is the explicit loading of the dll. It means that you first load the dll 'manually' using LoadLibrary and then retrieve the function pointers you want to call. This gives you some flexibility because you are able to manage the errors (if the dll is not present, LoadLibrary returns NULL, same with functions that don't exist,...).
There's another way which is the implicit loading: you let the compiler 'do the work' for you by including a header file and by linking to a static library both supplied with dll. The static lib contains information about how to load the dll (but not the dll code in itself). This is in general easier but it gives you less flexibility: if the dll is missing when you start your program, a windows error is shown and the program exits (and you can't do anything for it).
I suggest this article[^] if you want to see more in details how to do it.

As a test run for a much larger and more ambitious program, I have a small application where a user can generate a boolean algebra query from comboboxes of possible values and boolean operators.
Now lets assume that the user has created a syntactically correct expression (we've checked it with some other code), and that all the variables in the expression are valid and can be evaluated. Let's also assume for now that the output of the program window is now a CString which contains the expression with C++ valid boolean operators.
For example, lets say that we have CString expression which contains:
((X && Y) || Z)
Now I want to be able to process that expression and get a result. If I had a line such as:
bool result = ((X && Y) || Z);
I would have my result. Keep in mind that I need to keep this generic so that the user could input as simple or complex a query as needed.
My only thought is to do some awkward string processing to recursively move from any detected parenthesized section, and then have a switch statement or something to perform operations of AND, OR, NOT, etc on a pair of variables, and keep calling this for each found variable, moving outward from inner nested parentheses.
Is there a better way? Again, assuming that the input is "clean", if I somehow could just convert a CString into a code statement, it would process correctly...
Thanks,
Bill

Are you wanting to create this string based on the contents of the comboboxes?

Essentially, yes.
I have comboboxes with the necessary characters in plain text, but need to create the actual query. I can assemble it all into a CString which reads "((X && Y) || Z)" but I need to be able to get bool result = ((X && Y) || Z); out of that.

Actually it's really not that hard to write an evaluation function for this. Use a stack to push all tokens from left to right. Using the following rules using the above example ((X && Y) || Z)
1. If token is a variable, push its value, else push the token.
2. After each push, check if the top of the stack can be evaluated.
3. After each evaluation, check if the stack can be evaluated further.
4. When no more tokens, the result is in the stack.
When checking if the top can be evaluated:
1. Check for unary operators in stack top - 1
else
2. Check for binary operators in stack top - 1
else
3. Check for parentheses in stack top - 2 and top
(You may also want to check the surrounding values to make sure they are what they are supposed to be, unless you know you have a correct statement syntax)
Example
push (
push (
push X => TRUE
push AND
push Y => FALSE
push )
push OR
push Z => TRUE
push )
There are no more tokens and the result is in the stack. If the stack size is larger than 1, there is an error.
I bet this was not the answer you were hoping for.

Thank you for the response; I've thought about that approach a bit, and was able to implement it functionally in my project!

Is it possible to use the VC++ 2008 compiler with Visual Studio 2005, so that you benefit from the smaller code produced by the VC++ 2008 compiler, but yet keep compatibility with Win98 (ie. still use VC++ 2005 runtime libraries) ?
|
|
|
|
|
as long as you don't call specific APIs which Win98 weren't providing yet, yes, you can...
