I don't work with MFC. Is there a way to do it in C within the native API?
|
|

Well, since MFC is just a wrapper around the API, i'd say yes, in my oppinion what you need is an owner drawn menu, i think this[^] should help.

Hi,
In Internet Explorer, when I click on a link and go back to the previous site I am exactly at the same position of the document where I left. Even the link I clicked is still marked by a thin border.
I have an application where I keep track on the history on my own. Now I need exactly the same behaviour.
I think i need to save the "state" (scrollposition and "marked" link) in my history array and restore it afterwards when I load the old site again.
Does anybody know how to achieve this?
If this is hopeless it would also be enough to just save to current (scroll-)position. However, the loaded documents are complex with different divs which have overflow:auto, overflow:hidden etc. So I can't just get_body, query IHTMLTextContainer and afterwards get_scrollTop etc. because those would be the scroll stuff from the document itself...
Thank you for any hints!

As with most things, break the problem down into smaller parts.
Can you make a DLL?
Are you thinking of MFC? In which case, export a CMyWnd class, and do RegisterWindowClass (*) in the constructor.
If it's win32, take a leaf out of InitCommonControls, and export a function from your dll that registers the windows classes.
The first two parts have good articles here on CP.
You also need to work out what the problem you are solving is - that will have a big effect on your solution.

(*) from memory. Look up appropriate function!

Ys I can create the DLL but I want to know how we can add the custom class for the Button which is drived from CButton in the DLL, so that I can use that dll in my sdi application to create the button.
Thanks,

OK, so you can make a DLL.... Check.
And this is in MFC... Check.
So, there's only a few simple things to do:
1/ Make a header somewhere that both the dll code, and the later exe code can read. (I have a workspace include directory, normally).
Near the top, have code like this:
#ifdef IAINDLL
#define IAINEXPORT __declspec(dllexport)
#else
#define IAINEXPORT __declspec(dllimport)
#endif
When you write your CButton inheriting class, start like this:
class IAINEXPORT CIainButton : public CButton
{
};
In your project settings, make sure to add the following symbol to the defines: IAINDLL. That way, when code in the DLL sees the header file, it says "oh, this will be exported!", and when code elsewhere sees the header file, it says "aha, I will link to these class functions".
If you don't know how to write a custom CButton class, then Button Controls[^] is full of examples for you to follow.
Good luck,
Iain.

Hi,
I want to write an addin for visual studio, that will display a tooltip showing a certain datamember, when I hover the mouse over a MyClass object f.ex. Is this at all possible? I don't know how to get the information about what the mouse is hovering over. I need some links to reference docs. Thanks!

_Worksheet objSheet;
Range objRange;
-----------some code here----------------
objRange = objSheet.GetRange(COleVariant(A1),COleVariant(K4));
//at the following line I got the memory leak memory of my programme get increase
ret = objRange.GetValue2();
How to solve that problem

How do you know there is a leak? What are the types of the variables?

_Worksheet objSheet;
Range objRange;
-----------some code here----------------
// code to obtained the excel sheet pointer
objRange = objSheet.GetRange(COleVariant(A1),COleVariant(K4));
//at the following line I got the memory leak memory of my programme get increase
ret = objRange.GetValue2();
As I call the ret = objRange.GetValue2(); memory occupied by exe getting increased.
I see in task manager -> process . I have a timer of 1 second which poll data every secong form the excel file . if I do not start timer then there is no memory increase in excel file .

Hello everybody,
I created a service which runs nicely on my local machine.
If I like to test an existence of a file, which is located on a network-folder (net use g: \\...)
then the function _access returns me -1 (not exists).
If I call exactly the same function with the same filename in a standard application (not as a service)
then all works fine.
Is it an access-security problem, or do I use simply the wrong function to test the existence of a file?
(I don't wanted to use a fopen,fclose)
Big thanks for any ideas

what account is your service running under - default localsystem ?
if so, you'll need to change that so that the account you run under has network access (localsystem by default does not have network access, this includes shares iirc).. create a dedicated account for your service, give it the correct access, its better than localsystem
(if you google around a bit you should find more pointers on the same)
'g'

If your service runs under the local system/local service account, it has no rights to access network resources.
Try the network service user or create a new user and assign the login to this service.

Big thanks for your replies.
That seems logic, but it doesn't work ... it's seriously a configuration problem.
I'll make a workaround
Thanks you two

Try to see what GetLastError returns immediately after the call to __access, it might tell you something. There's a tool in Visual Studio that will give you the error text for each error id.
There is sufficient light for those who desire to see, and there is sufficient darkness for those of a contrary disposition.

Hello
I want to make a timer in maze.The timer should countdown to reach 0 and if the player doesn't reach to end he/she lose the game.
I want to denote that if player reach to end timer should stopped working.
How can I do it?
Thanks anyone help me.

I hope that you have the code for your "maze".
What kind of application is it? Assuming your main thread has a message pump, you could run a timer on a separate thread, and have it post a message to the main thread after the time is over. There may be other messages to be processed in the queue, but then again, Windows isn't an RTOS...

Create a secondary thread with a CTimer and a countdown counter; I don't think this is much difficult.
At each "pulse" (either compare delay or Sleep), send a message to the main application thread to display the time left and when the countdown is finished, send a message to the main application to display "You FAIL".
Max.
Watched code never compiles.

Why bother with a secondary thread if you're going to use window messages to inform the main thread? A vanilla timer set using SetTimer[^] is quite capable of achieving the same result more efficiently.

Sir, Here is your timer hasani2007. Its in 'dirty c code', clean it up.
set the variable count_down_time_in_secs in seconds for desired count down time.
The Code is self explanatory.
1 minute = 60 secs
5 minutes = 60x5 secs
30 minutes =60x30 secs
1 hour = 60x60 secs
#include <stdio.h>
#include <time.h>
int main ()
{
unsigned int x_hours=0;
unsigned int x_minutes=0;
unsigned int x_seconds=0;
unsigned int x_milliseconds=0;
unsigned int totaltime=0,count_down_time_in_secs=0,time_left=0;
clock_t x_startTime,x_countTime;
count_down_time_in_secs=10;
x_startTime=clock();
time_left=count_down_time_in_secs-x_seconds;
while (time_left>0)
{
x_countTime=clock();
x_milliseconds=x_countTime-x_startTime;
x_seconds=(x_milliseconds/(CLOCKS_PER_SEC))-(x_minutes*60);
x_minutes=(x_milliseconds/(CLOCKS_PER_SEC))/60;
x_hours=x_minutes/60;
time_left=count_down_time_in_secs-x_seconds;
printf( "\nYou have %d seconds left ( %d ) count down timer by TopCoder
",time_left,count_down_time_in_secs);
}
printf( "\n\n\nTime's out\n\n\n");
return 0;
}
.

A busy loop is perhaps not the best way to go about things.
