hi,
i want to know how i can let my network card send raw data(without TCP/IP and that stuff). and of course how to receive it.(OSI layer 3)
and of course... is it possible(because windows already uses the network card)

Hi all,
Anybody knows how to get the highlighted string from window application? For example, getting the highlighted string from IE or MS Word. I do not have any idea of implement it.
Cheers,
Tony
Enjoy Coding.

What kind of window? In a generic window you are limited to GetWindowText only.

:-OThank you for your answer. I am going to do the following works:
1) Highlighted a string in an MS Word document/ MS IE.
2) Press a Hotkey from keyborad to activate my application, and use the highlighted string in step#1 as the input parameter.
Does it possible to be done by VC++?
Cheers,
Tony

It is possible, but you have to use MS Word(MS Office) COM model.
You should use something like (check the dependencies):
#import "VBE6EXT.OLB"
#import "MSO9.DLL"
#import "MSWORD9.OLB"
After that the whole set of MS Word objects is exposed to your program

Hello
I got a little routine for checking a date field.
Now i want to automatically set the focus to that field by using f.e:
(where EF_DATUMINDIENST is the name of the text field)
(GetDlgItem(EF_DATUMINDIENST))->SetFocus();
but my idea was of making a function with as param. the name of that text field.
now i set for example a
CString fieldname = "EF_DATUMINDIENST"
and i call the routine here:
DoChecksAndSetFocusAt(fieldname);
but in the routine "DoChecksAndSetFocusAt"
i can't set focus on that control becz it believes it is a CString text
fieldname = result;
UpdateData(FALSE);
This of course doesn't work .. but i have no idea of how to make it work 
So i want to access the text field correctly.
Can anyone help me?
Thanks
Jens

make it : DoChecksAndSetFocusAt(UINT id) and just pass the control ID.
in C/C++, there's no way to go from a string to a variable name at run time.
-c
When history comes, it always takes you by surprise.

ok thanks, that worked great!

Ok
I've created a win32 dll project via VS. In this dll I'm creating dialog boxes and windows be be used by several diffent apps.
Here's an example of my creation of the dialogs:
hTemp =CreateDialog(hInstance,
MAKEINTRESOURCE(IDD_USER_STR_INPUT_DLG),
hWnd,
IuxUserStringInputProc);
if (hTemp == NULL)
error = GetLastError();
But it ALWAYS comes back null and the get last error returns an 1814 error, which is: ERROR_RESOURCE_NAME_NOT_FOUND and MSDN tells me: "The specified resource type can't be found in the image file"
What the heck does that mean? It kinda makes sense what it is telling me in that the resource I'm trying to create isn't there in the dll, but it's in the project and it shows up in my build options, so what gives
any help in the matter is GREATLY appreciated.
Thanks

See MSDN description for CreateDialog, pay attention to the hInstance argument

Doh!
Makes perfect sense now. LOL. thanks!

Ok digging deeper on this problem.
hInstance
Identifies an instance of the module whose executable file contains the dialog box template
since I am calling the CreateDialog within a function in a dll and passing the Hinstance from the application in, it's not the correct Hinstance.
how do I correct this? do I need to create an imaginary window in the dll before calling the CreateDialog and use the Hinstance from that???
This has me a little confused.
Any suggestions? Thanks!

hInstanse is the one that comes in DLLMain. Since it is almost first function that is called when DLL is loaded, you can save the value of it in some local variable, at that time.
|
|
|
|
|
I think you can use
(HINSTANCE)GetModuleHandle( _T("Your DLL File Name Here.dll") );
instead of the hInstance of the application  . Or, you can just use the saved hInstance value from DLLMain like AlexO suggested.

That's exactly what I ended up doing. I try to avoid globals if at all possible. That shared global memory in a windows app can bite ya.

Ok,
I've been at coding for a few years now, and I'm just now using the "new" operator. LOL. Now I have a question:
LPCTSTR lpUserStringInput = (LPCTSTR) new LPCTSTR (MAX_STRING_INPUT);
why isn't this valid? I get this error:
:\src\libdialog\libdialog.cpp(71) : error C2440: '=' : cannot convert from 'const int' to 'const char *'
Conversion from integral type to pointer type requires reinterpret_cast, C-style cast or function-style cast
So what am I doing wrong? And when I want to delete it I just want to do this:
if (lpUserStringInput != NULL)
delete lpUserStringInput;
right? I know how new/delete work with classes, but on individual variables I dunno. Thanks!

Many problems where. First, why use a LPCTSTR? That is a pointer to a constant string. Thus you are allocating a buffer you don't intend to modify?
Second, why are you casting the results of a new? 999 times out of 1000, it means you aren't allocating the right thing. new is specifically designed to not require the need to cast.
Third, "new LPCTSTR" will allocate one or more pointers to constant strings. Not strings themselves.
Last thing, if you want to allocate a string of length MAX_STRING_INPUT, then do this
LPTSTR lpUserStringInput = new TCHAR [MAX_STRING_INPUT];
Also, if you wish to delete an array, you MUST use delete [] and not just delete.

I'm going to patent thought. I have yet to see any prior art.

Thank you. Clears up alot of things for me
one more thing, when calling delete on an array do I need to loop through the array or does:
delete[] lpUserStringInput;
handle that?
Thanks a lot!!!

I'm all set guys. thanks alot!
I learn something new every day from this place Woo Hoo! Maybe one of these days I'll be a decent programmer becuase of all of you.
Thank you.

what you wrote roughly translates to
char* p = new char*;
you have to decide what ever you meant to do
char** p = new char*;
or
char* p = new char[25];
P.S. If I may, I would strongly recommend "C Programming Language (2nd Edition)"

Thanks AlexO
your recommendation is noted. Looking now for it.
Once again thank you.

Hi !!
As I was compiling my C++ project, Visual Studio (6.0) crashed and now, when I open my workspace, I get a message telling me the it cannot access the ClassView information file.....
I cannot see my classes anymore !!!
Does anyone know how I could recover the classview ???
Thank you for your help !

Thanks but I don't have any .clw files in my project folder......
Any other idea ??
Jerome

Have you got the project open in another copy of visual studio?
Sounds stupid and obvious, but I often find myself cursing at a broken classview, only to realise that I'd absent mindedly started visual studio twice (and the first copy has exclusive control over the classview stuff)
A reboot in situations like this can also be a magic fix (assuming you haven't tried that already) - sometimes software just goes mad

Help me! I'm turning into a grapefruit!
