 Hi All,
Seasons Greetings!!
Im Mirza Faizan, currently a trainee at ELECTRONICS AND RADAR DEVELOPMENT ESTABLISHMENT, DRDO, Bangalore. In my academic project, I have to develop a Device driver Hardware Acceptance Test for a communication card for Control and Display Unit of a RADAR. I have seen your project on www.codeproject.com, and immediatelt realized that you can be my help!! plz plz plz...
My problem is that I am developing GUI for the driver in VC++. And I am having trouble with the following thing:
1) I have to develop a GUI in which POST is done for 24V, 5V, 3.3V, 2.5V.
*If the check is successful, then the button should become GREEN and the caption on the button should be 'OK'.
*If the check is failed, then the button should become RED and the caption on the button should be 'FAILED'. And when the user click on button, a dialog box should appear telling him what to do next.
2) Please also do tell me how to declare variable (not attached with the controls, but extra variable where I should store values of voltages which are checked.
3) Please tell me how to add C,C++ code in the GUI developed in VC++. I mean, Im developing GUI in VC++ and writing device driver in C, C++
Please help me with this. I'll be highly obliged with this kind act of yours.
Regards

Hi All,
I have created many application on VC++ 4my company for there Networking department that allows me to view a remote desktop on my LAN using Socket client and server application (WinSock 1.1) . Here what i do is i install the server on the remote machine then i captures the desktop using SDK fn(),s and then passes it byte by byte using send() and recv() fn's.
I even hide my server application from task manager so that it is not visible and i make it start up thru registery so the admin has installed it on all the computers. they passes the ip adderss and justs connect it using client application
Now My Question is
Can there be some way on LAN where i can access remote desk top without installing the server program???
Could the Answer be accessing some Remote Procedural Call (RPC's)
Which topic or fn,s do i need to study??
I read that there r softwares which allows the Admin on LAN to moniter a computer without installing the server program.. They r some stand alone programs
Which topic or fn,s do i need to study??
Thnx in advance

you shd look for some image library that give you handle or display the jpg.
-->if you looking in COM/ATL
-->look for interface IPicture
---->if you looking in RAW MFC/API
--->look for CxImage In CP,best Graphics Library present in Town

hello,
im looking for retreiving a pointer to a function from its name stored in a string...
thx for help.
|
|
|
|
|
hi
well so for i got ur question the function name is itself a pointer to the address space of ur program
Suppose i want to make a pointer to a ftn that return UINT and take UINT as single argument
then prototype will be like this
UINT (*p2ftn)(UINT);
p2ftn=function;
p2ftn(23);
|
|
|
|
|
i allrdy know that. and thats not what i want to do.
ex:
void myFuncNameString (void)
{
foobar();
}
void main (void)
{
char* var = "myFuncNameString";
// Here I want to call myFuncNameString only knowing the string....

The only way I know of, is to get the pointer to a function exported in a dll.
The C/C++ compiler takes the name of your function and translates it to an adress, no meta information is preserved when the application is compiled.
That's why we got file specifications like dll and elf, they describe a format that allows for exporting function tables.
If it's a feature you really need, then you could use a Hashtable to store pointers to your functions mapped by their name.

hmmm...
u mean using some code like this:
typedef DWORD (*FCT_PTR)( bool pText);
struct MyStruct
{
char * name;
FCT_PTR funct;
};
const MyStruct funcHashT[] =
{
{ "foo", foo },
{ "bar", bar },
}
void foo (bool pText) { //blehbleh }
void bar (bool pText) { //blehbleh }
...
I think its ok for pure c functions, but my prob is that i need to make a new object only knowing his name (or his constructor name). same problem as above except that foo and bar are classes...
|

|
|
|

Template are out from my current knowledge  but ill take a look at them asap.
But, do u think can do the following using the post i paste before:
new funcHashT[i].funct (true);
????

The word you're looking for, I suppose, is Reflection. This is not possible in C++ for the same reasons as I mentioned before.
But you can of course work around the limitations, to do so requires a solid knowledge of the language and tools.
If you know, and understand, COM, you will realize that the interface IDispatch is invented for just that reason. Again, if you really need the feature, you could either use COM and IDispatch, or you could copy the technique.
What it all comes down to though, is that you're probably better of using C# for your project.

I find a workaround:
typedef void (*FCT_PTR)( bool pText);
struct MyStruct
{
char * name;
FCT_PTR funct;
};
void wrapper_foo (bool pText) { new foo(pText); }
const MyStruct funcHashT[] =
{
{ "foo", wrapper_foo }
}
class foo
{
public:
foo(bool pBool)
{
// Code
}
}
I tested this code in a very simple c++ project and it works fine.

hi,
I want to do Insert ,delete actions in a SQL Server Database using C++/MFC.

Try reading about CRecordset, if you want to use MFC, along with CDatabase.
Alternatively, you can use ATL helper classes and use OLEDB, in which case CDataSource, CSession and CCommand/CAccessor stuff is what you want.

an activex control is about to embeded in IE,if the activeX control access the oracle ,but demands the client don't want setup oracle's client ,how to realize it ?please tell me som .thanks a lot!

ahh can you rephrase this question?
You're saying you have an activex control which is embedded in IE
and that the control needs access to Oracle
the user doesnt want the activex control to talk to oracle and you want to know how to tell the active x control not to use oracle?
is this correct?
