Hi,
I am an experienced programmer in Linux, but new to Windows.
I want to develop windows XP driver for a PCI based device.
Also, I want to write a device capability Demonstration application.
I am free to select Visual Studio 6.0 to Visual Studio 2008.
1. Is it a good decision to do the Demo Application development in VC++ Dot-Net, and Driver Development in Non-Dot net environment?
2.Which version of Visual studio is suitable for me, considering the future usefulness of the technical knowledge I am acquiring.
3.Please suggest some good books for Windows XP Driver Development.
Thank You very Much
Jacob

IMHO yes.

The latest one.

Hi Guys,
Do we have any unicode equivalent to this _chdrive function?
I made my application unicode supporting one. previously it was working fine but now it is not working and application is crashing.
Previously it was having the value of 28 but now the value is 35. Why is it so?
code snippet:
----------------------
_chdrive(theApp.m_Dir[0]-'A'+1);
-------------------------------------------------
can anyone shed some light on this issue?
Thanks,
Rakesh.

_chdrive is completely independent of UNICODE, since it accepts an integer as argument (and not a string).
Rakesh5 wrote: Previously it was having the value of 28 but now the value is 35.
Which value are you talking about ? The return value of _chdrive ? That's impossible since it returns either 0 or 1.
Please clarify your question...

Hi,thanks for the reply...
int a = theApp.m_Dir[0]-'A'+1 ;
Can you please tell me what is the logic behind using 'A' + 1 ;
Can you help me??
Thanks,
Rakesh.

 You wrote the code but you don't understand what you wrote ??
Anyway, you are taking the first letter of the m_Dir string (which is probably a drive letter) and substracting the value of 'A'. This is because the letter 'A' has a specific ASCII code (which is not 1) but the A drive should be 1. Then you are incrementing the drive number by 1.

actually i did not write the code..my seniors have written.. am trying to learn what they have used ..
anyway thanks alot for your help...

So use the debugger to see what the value of a is.

This sounds like a very good question for Google.

Hi,
I would like to know if there are any ways to programmatically detect or monitor the file or folder being copied either by copy command(like on command prompt-- copy a b) or by using drag/drop(ctrl+c and ctr+v).
It would be helpful if you could give some pointers( preferably some APIs in vc++)
thanks and regards

You would probably need a File System Filter Driver for this.
Not a very easy task.
Look at the FileSpy sample in the Windows Driver Kit (WDK).

Thanks for the quick reply.I will look at FileSpy.....

I want to build an application with publish/subscribe model for UDP communication for a real time simulation system. I'm new to this communication model and need to know much about the publish/subscribe model. We are using the Client/Server model for the communication. Where can I get some details about this model and what is the middleware I should be using.
Thanks

I bet Google has lots of information.

GetOpenFileName() is Win32 API function which accepts a pointer to a OPENFILENAME structure. In this structure, you have to set up a member lStructSize to sizeof(OPENFILENAME) for Windows XP and above. But for Windows98 it must be OPENFILENAME_SIZE_VERSION_400. When I use an if statement to do it, compiler gives fatal error and stops :
OPENFILENAME ofn;
if(win98()==FALSE)
ofn.lStructSize = sizeof(OPENFILENAME);
else
ofn.lStructSize = OPENFILENAME_SIZE_VERSION_400;
Ofcourse I can make seperate functions for opening files in win98 etc. But what is a better way to do this.
Thank you

What is the error that you get?

This is what Pelles C Compiler displays :
Building MAIN.obj.
C:\Code\Hasher\MAIN.C(34): fatal error: Internal error: get_rule().
*** Error code: 1 ***
Done.
|
|
|
|
|
From the code that you pasted, I'm not able to figure out what the problem is.
The if condition looks perfect.
Is that on line 34 of main.c?
|
|
|
|
|
Yes. Its line # 34 in main.c
When I remove if statement and just set lStructSize to one of the values, the code compiles perfectly.
|
|
|
|
|
It seems that there is nothing unusual.
Give it a try by changing the name of the function "win98". It might confuse the compiler?

What does the win98() function do?

I am trying to sort a list using the insertion sort algo, but my application crashes. I think those pointers lost track by using the remove function. Is there a better way to sort except using the sort() (list.sort() function). It does not work too well with it since I am sorting by Departure Time of the object in the list.
Here is the code i wrote:
//Insertion sort to sort runs by departure time in the Res_RunList
int numruns = Res_RunList.size(); //the size of the list
ListOfRuns::iterator Tempitr1; //create itr poniters to navigate thru the list
ListOfRuns::iterator Tempitr2;
ListOfRuns::iterator Tempitr3;
ListOfRuns::iterator Tempitr4;
ListOfRuns::iterator Tempitr5;
ListOfRuns::iterator Tempitr6;
std::list <RDLRun*> TempList;
ListOfRuns::iterator Tempitr7;
Tempitr1 = Res_RunList.begin(); //points to the 1st element
Tempitr2 = Res_RunList.begin();
Tempitr6 = Res_RunList.begin();
for(int low = 1; low < numruns; ++low)
{
++Tempitr2; //points to low position
RDLRun *TempRun = (*Tempitr2); // store the data from low position in TempRun
int u = low -1;
Tempitr3 = Tempitr2;
Tempitr4 = Tempitr3--; //ponits to u position
//compare the time windows
while(u >=0 && ( (*Tempitr4)->GetDepartureTime() > TempRun->GetDepartureTime() ) )
{
Tempitr5 = Tempitr4;
Res_RunList.insert(Tempitr5++, (*Tempitr4));
Res_RunList.remove((*Tempitr5++));//to prevent duplicate
--u;
--Tempitr3;
}//end while loop
if(u > 0 || TempRun->GetDepartureTime() > (*Tempitr1)->GetDepartureTime())
{ Res_RunList.insert(Tempitr4++, TempRun);
Res_RunList.remove((*Tempitr4++));
}
else{
Res_RunList.insert(Tempitr6++, (*Tempitr1));
Res_RunList.remove((*Tempitr6++)); Res_RunList.insert(Tempitr1, TempRun);
}
}//end for loop
Thanks.

I don't see you using sort in your code.
Also, any insertion or deletion in the list renders the iterators invalid.
This can give you unexpected results.
