Hi. Has anyone tried to build up an Visual C++ application that sends messages using WAP's Push Access Protocol? I have. But I don't know how to do this. What tools can I use (for Proxy Gateway, for Phone Simulator) for my computer to become a stand-alone Push Initiator + Proxy Gateway + WAP Phone Simulator for my application to test on? Examples of code would be considered very usefull.
Thank you

I have some code here that I have been playing with to implement a elevator's computer. I have everything kind of mapped out in my head how it's going to work but am having a problem with converting a char to an int. I would like to send the char c to the thread "move( )" and use it as an int. So bacically, How do I convert a char to an int using only djgpp compiler and multi-c operating system.
Here is what I am working with.
void move(char c)
{
}
void getFloor(void)
{
DWORD32 timeout;
short c;
for(;;)
{
BYTE8 floor;
SetCursorPosition(8,10);
while(!ScanCodeRdy())
MtCYield();
floor=GetScanCode();
if ( !(floor & 0x80) )
{
c=ScanCode2Ascii(floor);
PutString(" Floor ");
PutChar(c);
}
}
}

For PocketPC 2002...
I'm using João's wizard dialog stuff and have some really weird stuff happening.
I'm doing this for several property pages:
CMyWizard::CMySheet()
{
}
CMyWizard::OnInitDialog()
{
CBaseSheet::OnInitDialog();
}
CMyWizard::InitWizard()
{
m_pgPtr1 = new CPg1(this);
m_pgPtr1->m_psp.dwFlags |= PSP_PREMATURE;
AddPage(m_pgPtr1);
m_pgPtr1->setData();
}
-----------------------------
CPg1::CPg1()
{
}
CPg1::OnInitDlg()
{
CBasePage::OnInitDialog();
}
CPg1::setData(CDataPtr* dataPtr)
{
m_ctrlCheckBox1.SetCheck(dataPtr->GetSetting());
}
and I'm calling it like this:
CMyWizard dlg;
dlg.InitWizard();
dlg.DoModal();
The program crashes when it tries to set the checkbox in the property page. The weirdness is that this works sometimes, and other times it doesn't.
Can anyone provide me with some insight?

My guess:
When you call InitWizard none of the windows have been created (they will be created on DoModal), so it is likely that m_ctrlCheckBox1.SetCheck may fail.
By the way: does setData have a default argument?

That's what I was thinking.
no - setdata doesn't have any defaalt parameters.
I hate property sheets... The should have a way to initialize pages when it's safe/okay to do so.

As an aside, how does this work:

m_pgPtr1->setData();

CPg1::setData(CDataPtr* dataPtr){ m_ctrlCheckBox1.SetCheck(dataPtr->GetSetting());}
Shouldn't the call to setData have a parameter? that could be your problem if the pointer is garbage. Unless you copied over your code incompletely, in which case, just ignore me.

Hello all,
I'am using CCeSocket overwriting OnReceive() function to develop an application that connects with a server using TCP.
Now, I need to connect to another server which uses UDP connections. I would like not to do many changes in my code. Is there any way of using CCeSocket for UPD connections? and, otherwise, Is there any similar class?
Thaks in advance

All I'm trying to do here is calculate the clock time of the computer with a couple C functions. The author of the book tells me "kind of" how to do it but still kind of vague.
I am getting a number, but it doesn't seem to be close to the clock speed of the computer(which is 133mhz, yeah yeah, I know it's slow but it boots my embedded apps okay)instead I'm getting a number like 231851640624.......about 20 digits long.
Can somebody tell me what I'm doing wrong with my code? Thanks.
#include "libepc.h"
int main(void)
{
ClearScreen(0x07) ;
SetCursorPosition(10,20);
DWORD32 timeout;
long long speed;
speed=CPU_Clock_Cycles();
PutUnsigned(speed,10,0);
timeout = Now_Plus(1);
while(Now_Plus(0) < timeout)
{
speed=CPU_Clock_Cycles();
}
PutUnsigned(speed,10,0);
return 0 ;
}

Hi experts,
I need to open the .cdb with sort order in API call, but I found that the .cdb converted from .mdb has no sort order, how can I define it in the Access .mdb and would it be lost after the convertion to .cdb?
thanks a lot.
|
|
|
|
|
Did you ty creating an index on the table with the required sort order?
Regards,
João Paulo

Thanks for your reply.
You're right!
The code is fine if I created the DB insided the PPC with
the sort order, but it fail when I created the database
from Access (officeXP version), and converted to .cdb
while copying it to the device.
The database has only 3 columns in it:
BookID(char 8), Content (char 90), Notes (char 255)
Actually I've defined BookID as the unique key index, so
how can I define the sort order for it?
Even if I type "BookID ASC" in the property page of the
Access' db, I get the same result.
Is it the ActiveSync's bug that lost the sort order? or
where else I shuld define the sort order?
If no solution for it, could you suggess any web-site teaching how to install and use SQL CE? expecially how to pack the whole thing including the SQL CE and install together for my client's PPC2002?
Please help!

I usually have no such problems, but I'm using either ADOCE or OLE DB. How are you accessing the database?
Regards,
João Paulo
|
|

|

well, I'm using API in eVC:
g_hDB = CeOpenDatabaseEx (&g_guidDB, &g_oidDB, _T("book"),
0, /* <- default sort order*/ 0, NULL);
I must use "0" for the sort-order since it get an open error if I specify any other value.
please advices, thanks.

The native db API is not really my speciality.  But if you want to take a look at ADOCE, check this:
A set of ADOCE classes[^]

Well, I feel pretty stupid. I've been trying for a week to get evc3 installed, and it just isn't working. Nobody here at works remembers what we had to do to get it instaled either.
I tried installing from just the evc3 CDs, and even after picking ARM and x86 emulation as the desired platorms, not only do I not get the x86 platforms, but I also don't get PocketPC 2002 (just PocketPC).
I've also tried starting from the CE3 Platform Builder "stack-o-discs", but with the same result. What the hell am I doing wrong?

I have two applications that I am working on. I want to be able to perform some routines in one application based on information from another app.
How can I or how do I go about sending messages between the two applications? Is it possible since I already know what the window class name is to obtain a handle to that window and then just post a message directly to it?
Thanks,
-Eric

Yes, you can do that. I suggest you use registered messages for that. Use the RegisterWindowMessage function to do that.
